Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to the method that terminal wireless resource distributes in a kind of TDD-CDMA system.
Background technology
At present, the development trend in mobile communication technology field is the fusion of TDMA (time division multiple access), CDMA (code division multiple access), FDMA (frequency division multiple access) technology, to maximize favourable factors and minimize unfavourable ones.FDMA is the multiple access technology that adopts frequency division, and Traffic Channel is given different users in different frequency allocations; TDMA is the multiple access technology that adopts the time-division, and Traffic Channel is distributed to different users in the different time periods; CDMA is the CDMA (Code Division Multiple Access) that adopts spread spectrum, and all users at one time, on the same frequency range, obtain Traffic Channel according to different spreading codes.That is to say, in the mobile communication system of using TDD (time division duplex) mode and CDMA technology, operable radio channel resource is decided by frequency, time slot and code channel three, on the frequency several slots is arranged, and on the time slot several code channels is arranged.
For example, existing TD-SCDMA (time slot-S-CDMA) system promptly is a system that integrates TDMA, CDMA, FDMA, and its multi-access mode is referring to Fig. 1:
System can be divided into different frequency range (FDMA) in frequency domain, can be divided into different time slot (TDMA) in the frequency domain bandwidth, and each business time-slot can be divided into 1～16 code channel (CDMA) by spreading code (SF=1,2,4,8,16) again.
Under the situation that the quantity of frequency and time slot is all determined, operable radio channel resource is by the spreading factor SF decision of the number of code channel and each code channel.For each code channel, spreading factor is big more, and it is long more then to transmit a required time that takies of bit, so transmission rate is low more; And spreading factor is more little, and transmission rate is high more.The spreading factor of the maximum of each code channel is 16, and minimum spreading factor is 1.In order to support identical air interface transmission rate, in a time slot, can use the bigger code channel of a plurality of spreading factors, also can use the less code channel of less spreading factor.For example, in a time slot, 16 spreading factors are that transmittability and 1 spreading factor of 16 code channel is that the transmittability of 1 code channel is identical, and are as broad as long in these two kinds of methods of salary distribution of network side, but these two kinds of methods of salary distribution are different to the requirement of terminal receiving ability.
The receiving ability of terminal depends on the disposal ability of the employed hardware of terminal.For terminal, SF=16 can be different on algorithm process with SF=1: for the time slot of SF=1, simple algorithm comparatively when terminal can adopt with respect to SF=16 when downlink data receiving, that is to say, though 16 spreading factors are 16 code channel with 1 spreading factor is that the air interface rate that can support of 1 code channel is identical, but with respect to the former, the latter is low to the requirement of terminal receiving ability.
In the prior art, network side can't learn that ability that terminal receives a plurality of time slots how.Usually, can support the time slot of SF=16, then for this terminal distribution Radio Resource the time, just always distribute the time slot of SF=16 if network side is always supposed terminal.When required downstream data rate acquired a certain degree, institute's distributed time slot number will surpass the receiving ability of terminal.At this moment, network side can think that terminal can not support the business of this speed by mistake, and in fact, if be the time slot of this terminal distribution SF=1, then terminal might be supported this speed.Particularly under the situation of multicarrier, the increasing the system that makes and can support downlink transfer speed faster of number of carriers, the treating capacity that terminal receives is also just bigger.At this moment, the difference of the time slot of SF=16 and SF=1 on algorithm complex is also just remarkable more to the influence of terminal receiving ability.If network side still comes distributing radio resource according to the time slot of SF=16, can make network side when carrying out RRM, can't carry out wireless resource allocation according to the actual conditions of terminal, the ability of terminal can't obtain best performance.

Embodiment
Core of the present invention is in the TDD CDMA mobile communication systems, report a message that comprises the time slot combination of sets by terminal to network side, this message has comprised that SF that terminal can be supported simultaneously is that 1 timeslot number and SF are the various combined situation of 16 timeslot number, has reflected the receiving ability of terminal.Network side comes to be the only Radio Resource of terminal distribution by the process of screening one by one according to this information, makes terminal capability obtain best performance.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 2, Fig. 2 shows the realization flow of the inventive method, may further comprise the steps:
Step 201: network side sends the message of its receiving ability of inquiry to terminal.
Prepare before terminal sends downlink service data, to send the message of an inquiry terminal receiving ability at network side.According to application need, can use the message in the existing protocol, also can set specific messages.
Step 202: terminal sends to network side by upstream message with its time slot disposal ability information that can support.Described time slot disposal ability information comprises at least: the various time slot combinations that terminal can be supported.
In this time slot combination of sets, indicate time slot type and number that terminal can be supported simultaneously, wherein, the time slot type is meant the dissimilar of spreading factor that this time slot adopts, can be 1,2,4,8,16.
Such as, this terminal can be supported the time slot of 20 SF=8 and the time slot of 9 SF=1 simultaneously, also can support the time slot of 26 SF=16 simultaneously, also can support the multiple time slot compound modes such as time slot of time slot and 10 SF=1 of the time slot of 5 SF=16,5 SF=2 simultaneously.According to actual needs, and consider the complexity of realization, can set set form and represent various compound mode, so that network side can correctly be discerned.
For the ease of identification, the filtration of network side to these different time-gap compound modes, to select Radio Resource according to the current resource situation of network near the transmission rate of terminal needs, can be to the combination of various time slots the complexity during to allocation of radio resources sorts according to network side so that network side filters each combination successively according to this order.Certainly, also can sort terminal and network side agreement sortord according to other modes.When network side is received the combination of these time slots, can be easily to every filtration the wherein.
Terminal can send to network side with its time slot disposal ability information that can support by existing user capability informational message; Also can its time slot disposal ability information that can support be sent to network side by proprietary message.To be described in detail later this.
Step 203: network side is the required Radio Resource of terminal distribution according to the time slot disposal ability information of receiving.
After network side is received the upstream message that comprises its time slot disposal ability information that can support of terminal transmission, therefrom take out the various time slot combinations that terminal can be supported, successively each time slot combination is filtered then, select the time slot combination of satisfying descending transmission rate requirement according to the current resource situation of network, and be combined as the required Radio Resource of this terminal distribution according to the time slot of selecting.
According to network resource situation at that time, in the various time slot combinations of terminal to report, might just in time not meet the combination that required descending transfer rate requires, at this moment, network side can provide Radio Resource near the transfer rate of terminal needs according to alternative Radio Resource at that time.Like this, can be very not big to the influence of terminal processing capacity, and can satisfy the downlink transfer rate requirement.
Step 204: it is this terminal use's service data transmission that network side uses assigned radio resource.
The front is mentioned, and terminal can send to network side with its time slot disposal ability information that can support by existing user capability informational message; Also can its time slot disposal ability information that can support be sent to network side, below this is elaborated by proprietary message.
In the prior art, network side is being prepared when terminal sends downlink service data, at first can send the message of an inquiry terminal receiving ability earlier, terminal is after receiving this message, can respond the user capability informational message to network side, in this message, comprise the communication capacity information that some terminals can be supported.

Wherein, the maxCombination variable is meant the number of possible maximum combinations.
In addition, can also be by setting proprietary message, the time slot disposal ability information that terminal can be supported sends to network side.
Such as, set user's time slot disposal ability message, in this message, comprise the time slot disposal ability information that this terminal can be supported, when network side is prepared before terminal sends downlink service data, send inquiry terminal to terminal and support time slot disposal ability message; After terminal receives that the inquiry terminal of network side transmission is supported time slot disposal ability message, respond user's time slot disposal ability message, the time slot disposal ability that terminal can be supported is informed network side to network side.
The time slot disposal ability information field that terminal in this message can be supported also can adopt expression mode same as described above.
For example, if represent with round parentheses: (timeslot number of supported SF ≠ 1, the timeslot number of supported SF=1), terminal can send such combination to network side so: { (25,0), (20,7), (10,20) }.
Terminal has sent 3 combinations to network side in this embodiment, wherein maximum supported timeslot number is 30 (the third combinations), but the time slot of 10 SF ≠ 1 and the time slot of 20 SF=1 are only supported in this combination, and can only support the time slot of 25 SF ≠ 1 in first kind of combination.
The present technique field personnel know, the big more least resource unit that can distribute of SF is just more little, be beneficial to flexible allocation so more concerning network side, and concerning terminal, SF is big more, and the complexity of algorithm is just big more comparatively speaking, and is just high more to the requirement of receiving ability.Therefore, in the present invention, can according to network side easily principle each element in the time slot combination of sets is sorted, be about to network side the combination of easy distribution come the front.
By last example as seen, putting in order of element is that capacity is in front little in the combination of sets, in the back capacious, and (25,0) but is the easy to handle situation of network side, because in this case, network side is free to make up scattered Radio Resource (SF=16 is minimum resource units) and uses for terminal.
By existing user capability informational message its time slot disposal ability information that can support is sent to network side, network side according to this information be this user's distributing radio resource flow process as shown in Figure 3, may further comprise the steps:
Step 301: network side sends the message of inquiry terminal receiving ability.
Step 302: terminal sends to network side by the user capability informational message with its time slot combination of sets that M element arranged that can support.
Step 303: variable K=0 is set, and this variable is represented the sequence number of each time slot combination in the time slot combination of sets that terminal supports.
Step 304: network side obtains the combination of K group time slot: M1=supports the number of time slots of SF=1; Mn=supports the number of time slots of SF ≠ 1.
Step 305: judge whether the combination of K group time slot satisfies the downloading rate of terminal needs.
If satisfy the downloading rate of terminal needs, then enter step 306: judge further whether present usable radio resources satisfies the requirement of Mn and M1 combination.
If satisfy the requirement of Mn and M1 combination, then enter step 307: the Radio Resource that satisfies Mn and M1 combination requirement for terminal distribution.
Otherwise, enter step 308:K=K+1, promptly from the time slot combination of sets, choose down the set of time-slot combination.
If the downloading rate of terminal needs is not satisfied in the combination of K group time slot, enter step 308:K=K+1 equally, promptly from the time slot combination of sets, choose down the set of time-slot combination.
Then, enter step 309: judge whether K equals M, that is to say whether each time slot combination in the time slot combination of sets is all filtered.
If also have optional time slot combination in the time slot combination of sets, then return step 304: choose down the set of time-slot combination and filter.
If do not had the combination of optional time slot in the time slot combination of sets, then entered step 310: provide Radio Resource near terminal needs downloading rate according to current alternative Radio Resource.
At present, for on further satisfying/the asymmetric demand of downstream data traffic, 3GPP (third generation partner program) has introduced HSDPA (high speed downlink packet access) technology in the R5 agreement, it has solved the contradiction between system's covering and the capacity well, promote power system capacity greatly, satisfied user's high speed business demand.The HSDPA technology can be used for carrying polytype business, different business QoS (service quality) difference, time delay also there is different requirements with throughput, for example professional requirement that usually time delay is had the comparison strictness of stream, and interactive class and background classes are relatively loose to the requirement of time delay.Usually, when multiple business and when depositing, stream is professional should to have higher dispatching priority.And, can use the multi-carrier transmission downlink data in order further to improve downlink transfer speed.In this case, utilize the present invention, make network side fully understand the descending receiving ability that terminal can be supported, thereby provide sufficient more information when carrying out RRM for network side, making network side can carry out efficient radio resource distributes, and then the operational efficiency of elevator system greatly, enhanced system is supported the ability of high-speed downloads.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
