Description

A method, device and system for realizing paging in a wireless communication system

technical field

The invention relates to the technical field of optical network communication, in particular to a method, device and system for realizing paging in a wireless communication system.

Background technique

In a wireless communication system, each user is connected to the network side through a wireless channel. For users in the wireless system, users can be divided into active state users and idle state users according to the user status. Active state users are users who are accessing the system or have already connected to the system and are conducting business. Idle state users are users who have not yet connected to the system. Users in the listening phase.

The communication service is divided into the calling user and the called user according to the initiator, and the called user initiates the wireless communication through paging. In order to save power, users in the idle state or some active states periodically monitor the paging channel, and identify which users are being paged by the system in the paging channel. After receiving the paging, such users can know that they are being called by the network side. So as to carry out corresponding processing.

Quick paging is a paging indication added to further save the power consumption of the terminal, because the network side does not always have paging at every moment, so it wakes up the user to listen to the paging channel at some moments when the user is not required to monitor the paging channel. Calls often cause ineffective power consumption for users. Therefore, a quick paging channel is added to indicate whether a user is paged at the next moment, and the user only monitors the paging channel after receiving the quick paging indication. The quick paging indication may be for one user, or for a group of users, or even for all users residing in a cell. The paging channel is generally a broadcast channel in a sector, and all users can receive or send.

Since users in a wireless communication system are often mobile, the network side generally does not need to know the exact location of the user. The network side divides the wireless network into several location areas according to the network load, that is, the paging area. When the user moves and the location changes, it will automatically Find out whether the location area has changed, and if there is a change, initiate a registration to the network side, and inform the network side of the user's location area. When the network side needs to send paging to the user, it only sends it in the location area (a group of cells) where the user is currently located. By changing the size of the location area, the user registration overhead caused by the change of the location area can be controlled.

If signals from different sectors are sent on the same subcarrier group in the same format, the signals can be combined naturally, thereby greatly improving the received signal-to-noise ratio. Among them, OFDM (Orthogonal Frequency Division Multiplexing) is widely used in mobile systems due to its good anti-multipath capability, and the OFDM system is very suitable for soft combining applications.

In quick paging, users often do not need to monitor the paging channel at every moment, so a paging cycle is set for each user in the wireless communication system, and the user wakes up to monitor the paging channel only in his own paging cycle. The network side randomly distributes the paging load by randomizing the time when the user wakes up.

The currently commonly used OFDM-based paging channel Qualcomm proposes a quick paging scheme in 802.20 as follows:

The paging mechanism of the 802.20 system is to send a paging message every two superframes, and send it on the pBCH1 (primarybroadcast channel 1) of the superframe Preamble (prefix) whose superframeindex (superframe sequence number) is an odd number. The structure of Preamble is shown in Figure 7.

The composition of each field and message block of pBCH1 is as follows: the most important blocks are QuickPageblock and QuickChannelInfo block, and the paging message is sent in QuickPage block.

Field Length(bits) LoadControl 2 DataCtrlOffset 4 ACKCtrlOffset 4 BlockType0 2 QuickPage block 0 or N _{QP_BLK} QuickChannelInfo block 0 or as specified by Overhead MessagesProtocol Block Type1 0 or 2 QuickPage block 0 or N _{QP_BLK} QuickChannelInfo block 0 or as specified by Overhead MessagesProtocol Block Type2 0 or 2 QuickPage block 0 or N _{QP_BLK} QuickChannelInfo block 0 or as specified by Overhead MessagesProtocol Block Type3 0 or 2 QuickPage block 0 or N _{QP_BLK} QuickChannelInfo block 0 or as specified by Overhead MessagesProtocol Reserved Variable

There are two ways to send paging: one-step paging and two-step paging. The paging method is determined by the 3bit NumPages field of the QuickPage block. If NumPages=0, it means that there is no paging message, and the paging content is filled with 0, so the QuickPage block will be ignored. If NumPages=1, it means that there is 1 paging message, and the message contains 32-bit UATI, as shown in Table 1 below. This type of paging is called one-step paging.

area Length (bit) value quick page number 3 1 User ID 32 Complete ATI content for one user reserved bytes undefined

For the case of more than 1 page, if 2<=NumPages<=8, it means 2-8 quick pages respectively, as shown in the following table 2 for the case of 2 pages. As the number of user groups to be paged increases, the number of quick pages will increase. When the total length remains the same, the number of bits that can be placed in quick pages for each group of users will decrease.

area Length (bit) value quick page number 3 2 User ID 16 ATI of a group of users with the same lower 16 bits User ID 16 ATI of a group of users with the same lower 16 bits reserved bytes undefined

If it is satisfied that the lower 4 bits of the RQuickPage (quick paging field) of the AT (terminal) match any RQuickPage field in the message, a QuickPageReceived (paging reception) indication is generated.

RQuickPage is generated by SessionSeed (session seed) and a set of algorithms, and each AT has its own unique RQuickPage. Paging messages are sent on superframes with an odd superframe index. If there are zero pages in the QuickPage block, all users listening to the page ignore this message. If there is only one paging in the QuickPage block, the user who monitors the paging will compare the ATI field in the paging message with the UATI (user identification code) stored in the public data (public data) of the Address Management Protocol (address management protocol) in the AT ) match, if matched, then generate a ControlChannelMAC.PageReceived indication (control channel MAC paging received indication) primitive, and transfer to the Access State (access state) of Idle State Protocol (idle state protocol), and start random access process. If there is more than one paging in the QuickPage block, after all ATs read the complete UATI from the corresponding resources of the corresponding F-DCH, they will compare the complete UATI fields in the paging message with those of the Address Management Protocol in the AT The UATI stored in the public data matches. If it matches, a ForwardTrafficChannelMAC.PageReceived indication (forward traffic channel MAC paging reception indication) primitive is generated and transferred to the Access State of the Idle State Protocol, and random access is started process.

The above scheme can greatly reduce the number of users who wake up invalidly. The paging message in pBCH1 is broadcast for users in the same sector, and soft combining cannot be performed between different sectors, so the performance cannot be improved.

Aiming at the problems in the above-mentioned prior art 1, the prior art 2 proposes that the paging channel in the same paging area adopts the same format and occupies the same channel for broadcasting, so that the paging channel between the cells can be soft combined to improve the performance of the paging channel. For the specific implementation process, refer to the Chinese patent application No. 200610071235.5 and the patent application titled "A Paging Method in a Wireless Communication System".

Prior Art 2 The paging channels in the same paging area adopt the same format and occupy the same channel broadcasting method, so that the paging channels between the cells can be combined softly, but the diversity gain and paging performance are not obtained. cannot be further improved.

Detailed ways

The core idea of the present invention is to provide a method, device and system for realizing paging in a wireless communication system, in which at least two subgroups jointly transmit paging to the terminal in the form of space-time/space-frequency transmit diversity, and further obtain transmit diversity gain , to increase paging channel performance.

Embodiment one:

The present invention provides a method for realizing paging in a wireless communication system. The operation flow of an embodiment of the method is shown in Figure 1, and the specific operations are as follows:

Step 1: dividing a paging area into at least two groups, dividing the group into at least two subgroups, and broadcasting information about the divided groups and subgroups;

The wireless communication system divides the paging area into several groups according to hardware implementation conditions and/or actual site distribution, and each group is composed of several sectors or cells, and the sectors in a group can be jointly scheduled, and at the same time Neighbors, the signals of other sectors in the same group seen within the coverage of any one sector are stronger, the system ensures that all sectors are in a certain group, and in order to enable soft combining, a paging group Groups of sectors require time and frequency synchronization.

Each group after the above division is divided into at least two paging subgroups, and each sector will be in a certain paging subgroup. Each paging subgroup may include different sectors in the same cell, or may include different sectors in multiple cells. A method for dividing paging subgroups according to an embodiment is shown in FIG. 2 , and paging group A is divided into two paging subgroups P0 and P1.

The system broadcasts the information of the group A and subgroups P0 and P1, including: group/subgroup identifier, sectors included in the subgroup, general scrambling code information, and so on. Simultaneously broadcast pilot transmission patterns, orthogonal sequence assignments, etc. for subgroups P0 and P1.

The channel resource information occupied by paging, such as time-frequency resource location, scrambling code, encoding and modulation mode, etc., can be broadcast or agreed upon in advance.

Step 2: The subgroup jointly sends paging information to the user terminal using space-time or space-frequency codes;

When it is necessary to perform paging in the paging group A, the paging subgroups P0 and P1 can use space-time or space-frequency transmission diversity to perform joint paging for the terminals.

The space diversity technology is also called antenna diversity, which is realized by a plurality of antennas or antenna arrays arranged separately in space at the transmitting end/receiving end. A copy of the transmitted signal arrives at the receiver in the form of spatial redundancy. Since different antennas are used to transmit the same information, space diversity does not bring about any loss in bandwidth utilization. Among them, the Alamouti code is the first space-time block code that provides complete transmit diversity gain for a system with two transmit antennas. It is a simple two-way diversity transmission structure. The block diagram of the space-time block code encoder is shown in Figure 3 As shown, at a certain moment (or a certain frequency point), the symbols transmitted by the two antennas are respectively C1 and C2. And at the next moment or adjacent frequency points, the two antennas transmit another two symbols - C2 ^* and C1 ^* (where ^* represents complex conjugate), so as to obtain transmit diversity gain. In this way, if the Alamouti code is used to realize macro-diversity between two sectors, a greater gain can be obtained than simple sector soft combining.

In this embodiment, for the paging subgroups P0 and P1, a feasible transmission method using the Alamouti code for the space-time or space-frequency code is as follows: the transmission mechanism is as shown in Figure 4,

Sending information X in the P0 paging subgroup={..., S1, S2,...}, sending information X' in the P1 paging subgroup={...,-S2 ^* , S1 ^* ....}.

Such as using space-time transmission macro-diversity: for the terminal AT, at the same frequency point, the transmission signals of the P0 subgroup sector and the P1 subgroup sector at the time t are respectively S1, -S2 ^* ; the P0 subgroup at the time t+1 Sector and P1 subgroup sector transmission signals are S2, S1 ^* respectively.

Such as using air-frequency transmission macro-diversity: for the terminal AT, the signals sent at the frequency point f1, the P0 subgroup sector and the P1 subgroup sector are respectively S1, -S2 ^* at the same time; at the frequency point f2, the P0 subgroup The group sector and the P1 subgroup sector send signals S2, S1 ^* respectively.

In the above method, the subgroups jointly provide paging for the terminal, and for the cells in the same subgroup, the soft combining technology can still be used to page the terminal. In order to soft-combine all paging information from the same subgroup, all sectors or cells in the same paging subgroup send the same paging content to the terminals monitoring the paging in the same way. For example, the same paging message is broadcast using the same channel resource and the same scrambling code, and the paging information is directly energy combined; or, the same paging information is broadcast using different scrambling codes, and the maximum ratio combining is performed.

Step 3: According to the information in the system parameter message broadcast by the system, the AT decides which method to use for data reception and channel estimation to receive paging;

For ATs that cannot support space-time/space-frequency transmission diversity, such as some low-protocol version ATs that cannot handle space-time or space-frequency codes, the system can use time division or frequency division. Protocol version AT paging resources are staggered. For example, the paging group can use different frequency channel resource information to send paging to the terminal, for example, allocate frequency resource f1 to low-version AT, and allocate frequency resource f2 to high-version AT, and the occupied different frequency channel resource information is determined by The protocol agrees or the system broadcasts within the paging group. The low-protocol version AT receives pages from the paging group sent on frequency f1 and applies soft combining techniques to the page information. Since the paging information sent by the system uses different channel resources from the paging for high-version terminals, the low-version terminals will not be interfered by other high-version terminal paging, and because it uses soft combining technology, the paging performance remains the same. be greatly improved. However, for the higher version AT, the space-time code transmission method can still be used at the frequency f2, and the soft combining gain and the transmission diversity gain can be simultaneously obtained in the manner of the sub-paging group.

Or do time-division processing on the paging process, within a certain period of time, send the same paging message in the same paging group, so that the channels of each sector or cell can be received by soft combining; Combination and transmit diversity combined method for paging.

To accurately receive the data sent by the forward channel, the AT must accurately perform channel estimation on the forward transmission channels in the P0 and P1 paging subgroups respectively. Therefore, the AT needs to be able to accurately distinguish the pilots in different paging subgroups. For pilot design, the system can adopt the following rules:

1) The pilots in the P0 and P1 paging subgroups adopt different time-frequency transmission modes;

If transmitted at different times or at different frequencies, the positions of the pilot symbols do not overlap with each other in the time/frequency domain. For the specific pilot transmission mode, several pilot patterns can be pre-determined through the protocol, and then the system broadcasts a system parameter message, indicating how each paging subgroup uses the pilot transmission pattern.

2) The pilots of the P0 and P1 paging subgroups are sent at the same frequency at the same time (overlapping each other), but they are modulated with different orthogonal codes, such as different Walsh (Walsh codes) codes can be used to distinguish them. The orthogonal codes can be specified by protocol or broadcast and assigned to different paging subgroups.

When the AT receives, it uses the orthogonal code matching of the corresponding paging subgroup to decode the pilot signal of the corresponding paging subgroup, so as to perform channel estimation.

Another embodiment of the method of the present invention is that subgroups use space-time diversity technology to jointly send paging to the terminal, but the sending method is different, as follows:

Step 1: dividing a paging area into at least two groups, dividing the group into at least two subgroups, and broadcasting information about the divided groups and subgroups;

The difference from Example 1 here is:

1. The sectors between the two subgroups do not need strict time synchronization;

2. There is no need to broadcast the pilot transmission mode, orthogonal sequence assignment, etc. of the subgroups P0 and P1, and this embodiment does not need to carry out the orthogonal pilot design in Embodiment 1;

Step 2: The subgroups jointly send paging information to the user terminal by using cyclic shift diversity;

The cyclic shift diversity is a kind of space-time diversity, which is different from the diversity form of Alamouti code. For the paging subgroups P0 and P1, a possible transmission method using a cyclic shift code is as follows:

The content of the information sent in the P1 paging subgroup is the same as that in the P0 paging subgroup, except that there is a certain delay in time. For example, for a terminal AT, at the same frequency point, the P0 subgroup sector sends a signal S at time t; and the P1 subgroup sector sends a paging signal S at time t+1. This method does not need to go through complex coding, and can obtain the transmission time diversity gain on the basis of soft combining, and the performance of paging is further improved.

In this embodiment, because P0 and P1 send the same paging information, but there is a time shift, for the terminal, it is equivalent to adding a multipath, and the high-version and low-version terminals can coexist. Time diversity gains are obtained, and there is an improvement in performance especially for paging of non-frequency selective channels.

The above two embodiments are cases where one paging group is divided into two subgroups. In actual operation, the number of subgroups is not specified and is determined by network planning. For example, it can be divided into three paging subgroups, as shown in Figure 5 below:

Divide the paging group A into three subgroups P0, P1, and P2. When the user is at the boundary of P0, P1, or P2, the three subgroups jointly use space-time or space-frequency transmit diversity to send paging to the terminal, and the terminal The macro diversity gain can also be obtained in the same way.

The present invention provides a system for implementing paging in a wireless communication system. The structure of an embodiment of the system is shown in FIG. 6 , including a paging implementing device and a paging receiving device.

The device for implementing paging is set on the network side of the wireless communication system, including:

The paging area grouping module is used to divide the paging area into several groups according to hardware implementation conditions and/or actual site distribution, and divide the groups into at least two subgroups according to the system network planning.

Simultaneously store and broadcast relevant information of subgroups, including: pilot transmission mode, orthogonal sequence assignment, etc., and also store pilot transmission modes corresponding to each subgroup;

A diversity transmission management and control module, used to control each subgroup to send paging information to the user terminal in the form of space-time or space-frequency code transmission diversity;

The soft combined transmission control module is used to control all sectors or cells in the same paging subgroup to broadcast the same paging message to the receiving terminal using the same channel resource and the same scrambling code.

The paging receiving device is located on the user side, including:

Memory module: used to store system parameter information and data;

Combined receiving processing module: used to control the soft combined receiving processing of the paging messages of the same paging subgroup;

The diversity transmission management and control module is used to control each subgroup to send paging information to the user terminal in the form of space-time or space-frequency code diversity among different subgroups, so as to realize diversity gain. Use the soft combined transmission control module to control all sectors or cells in the same paging subgroup to use the same channel resources and the same scrambling code to broadcast the same paging message to the receiving terminal, so that the user can control each paging subgroup The paging information can be soft-combined respectively, and the paging receiving device decides which method to use for receiving and channel estimation according to the system parameter information in the memory module, uses the diversity receiving processing module to jointly receive and process the paging information, and utilizes the combined The receiving processing module performs soft combining receiving processing on the paging messages of the same paging subgroup.

In summary, the present invention further divides the sectors of the same paging group under the same paging area, so that the paging channels between the sectors can be combined softly and/or obtain macro-diversity gain, further improving the paging efficiency. Channel performance, especially for users at cell boundaries. The present invention also designs the pilot frequency of each paging subgroup in certain space-time/space-frequency transmission diversity modes, so that the terminal can accurately perform channel estimation on the forward channel of each paging subgroup.
