Description

 Method and terminal for combining transmission power control commands

 The present invention relates to a high speed downlink packet access (HSDPA) technology of a UMTS radio access network (UMTS radio access network, hereinafter referred to as UTRAN), in particular, a transmission power. The combination of the control command (Transmit power control, the following cylinder: TPC) and the terminal (User Equipment, the following cylinder: UE). Background technique

 The service characteristic of the wireless communication packet service is that the transmission of its data is bursty, that is, the packet data is intermittently transmitted. In a complete business process, the number of data interruptions can be very large. For example: In a web browsing service, usually, a download webpage with data transmission is alternated with a webpage webpage without data transmission. In addition, there are still some businesses that require long-term sporadic data transmission. In a service, if the data transmission is carried out, the same connection state is maintained, that is, when there is no data transmission, the same network resources are allocated according to the data transmission, which wastes network resources and limits the network resources. The number of users online at the same time.

Currently, the main factor limiting the number of simultaneous users is uplink interference. In order to reduce the uplink interference and increase the number of simultaneous users, the 3rd Generation Partnership Project (3GPP) RAN has established a permanent online work project with the goal of not being between the UE and the UTRAN. The inactive moment of data transmission enables the UE to maintain the connection state of the cell-dedicated channel (CELL_Dedicated Channel, CELL_DCH) for a long time, and consumes less resources of the air interface, and the service recovery time is less than 50 ms. In order to achieve this goal, in the version of the 3GPP version 7 (hereinafter referred to as: R7), when the UE and the UTRAN are inactive or the data transmission is inactive, the DPCCH uses discontinuous transmission (Discontinuous Transmission). DTX) mode. In addition, in order To enable the UE to save power, the UE may adopt a discontinuous reception (Discontinuous Reception, DRX) mode according to the parameters configured by the UTRAN, and the DTX and DRX modes between the UTRAN and the UE are called continuous packet connectivity (Continuous Packet Connectivity, below). The barrel is called: CPC) mode. The UE may set a Discontinuous Transmission-Discontinuous Reception_STATUS (DTX_DRX_STATUS) variable to identify whether it is in the reflected CPC mode. When the UE is in the CELL-DCH state; and the variable high speed downlink shared channel RECEPTION (hereinafter referred to as: HS_DSCH_RECEPTION) variable and Enhanced Dedicated Channel_TRANSMISSION (hereinafter referred to as: E_DCH_ TRANSMISSION) variable values are True; and no DCH transport channel is configured; and a discontinuous transmission and reception parameter variable (Discontinuous Transmission-Discontinuous Reception-PARAMS, below: DTX_DRX_PARAMS) is set for storing the parameter configuration related to the CPC mode; When the "DTX-DRX timing information" information element is configured to the parameter related to the CPC mode sent by the network side, the UE sets the value of DTX_DRX_STATUS to True, indicating that the UE is currently in the CPC mode, and DTX and DRX can be performed.

 When the value of DTX_DRX_STATUS is True, the uplink DPCCH and the Fractional-Dedicated Physical Control Channel (F-DPCH) may continue to transmit continuously in the delayable radio frame, after which the UE will discontinuously transmit. The value of the Discontinuous Transmission (Discontinuous Reception-mode, the following cylinder: DTX_DRX_mode) is set to 1, namely: DTX_DRX_mode=l. When DTX_DRX_mode =1 and the uplink discontinuous transmission is activated by the base station (hereinafter referred to as NodeB), the terminal sets the value of the uplink discontinuous transmission mode (UP Link_Discontinuous Transmission, mode) to 1, ie: UL_DTX_mode=l, Start uplink discontinuous transmission, otherwise UL_DTX_mode=0. Similarly, when DTX_DRX_mode=l and the downlink discontinuous reception is activated by the NodeB, DL_DRX_mode=l, the downlink discontinuous reception is started, otherwise DL_DRX_mode=0.

When the UE performs soft handover, a wireless link is established simultaneously with the NodeBs of multiple cells (Radio Link, the following cylinder is called: RL), all NodeBs that establish RL with the UE belong to the active set of the UE, and all the wireless links belonging to the same NodeB form a radio link set (hereinafter referred to as RLS). When the UE performs DTX during the soft handover, the following two situations occur: The first case:

 The value of DTX_DRX_STATUS is True, and DTX_DRX_mode=l. At this time, only the NodeB of the serving HS_DSCH cell of the UE can control the values of UL_DTX_mode and DL_DRX_mode through the Shared Control Channel for HS-DSCH (HS-SCCH) command of the HS-DSCH of the layer 1. The NodeB serving the HS_DSCH cell cannot know the control of the value of the UL_DTX_mode of the NodeB serving the HS_DSCH cell, so that it is impossible to know whether the UE is currently in the DTX mode, and the DPCCH transmission time cannot be known. At this time, the NodeB of the non-serving HS_DSCH cell defaults to UL_DTX_mode=l, that is, when the UE is currently in the DTX state, the DPCCH is detected in the DTX pattern, and the corresponding TPC is generated and transmitted to the UE through the downlink F-DPCH. The default UL_DTX_mode value for the NodeB of the non-serving HS_DSCH cell may not match the actual value of UL_DTX_mode.

 The second case:

 UL_DTX_mode=l, the discontinuous transmission of the uplink DPCCH is defined as: in one time slot, when any one of the following conditions is met, the UE performs uplink DPCCH transmission in the time slot:

 1 . A Hybrid Automatic RePeat Request ACK (hereinafter referred to as HARQ-ACK) is transmitted on a High Speed Dedicated Physical Control Channel (hereinafter referred to as HS-DPCCH);

 2. The channel quality indicator (Channel Quality Indicator, CQI) is transmitted on the HS-DPCCH.

 3, in the time slot, the uplink data is transmitted through an Enhanced Dedicated Channel (hereinafter referred to as: E-DCH);

4, the time slot belongs to a time slot defined by a transmission structure of a Dedicated Physical Control Channel (DPCCH); 5. The time slot has a preamble and a postamble transmission of the uplink DPCCH. Condition 1 and condition 2 are the case of transmitting the uplink HS-DPCCH, and the DPCCH needs to be transmitted. Since only the transmission time of the NodeB HS-DPCCH serving the HS_DSCH cell and the corresponding DPCCH, the NodeB of the non-serving HS_DSCH cell cannot be learned; Centralized all NodeBs can know the transmission of DPCCH under conditions 3, 4, and 5.

 In the first case and the conditions 1 and 2 of the second case, the NodeB that activates the centralized non-serving HS_DSCH cell cannot know the transmission time of the uplink DPCCH, and thus cannot correctly detect the uplink DPCCH, generate and send the TPC to the UE; In the second case, under conditions 3, 4, and 5, all NodeBs in the active set can learn the uplink DPCCH transmission, that is, the NodeB of the non-serving HS_DSCH cell is in the set uplink DPCCH DTX transmission pattern time slot, uplink E-DCH. The uplink DPCCH transmission time slot accompanying the transmission and the uplink and downlink time slots of the uplink DPCCH are transmitted, and the uplink DPCCH sent by the UE is detected, and the TPC is transmitted to the UE through the downlink F-DPCH in the corresponding time slot. In the uplink DPCCH transmission time slot that can be learned by the NodeB of the non-serving HS_DSCH cell, the UE combines the TPC commands carried in the downlink F-DPCH corresponding to the uplink DPCCH transmission time slot sent by all the RLSs in the active set, otherwise the UE only merges the service. The TPC command carried in the downlink F-DPCH corresponding to the uplink DPCCH transmission slot sent by the RLS of the HS_DSCH cell, while ignoring the TPC commands of other RLSs, does not participate in the merging of the corresponding TPCs sent by the NodeBs of the non-serving HS_DSCH cell.

 When the UE performs soft handover in the CPC mode, in the above two cases, the UE does not merge the TPC sent by the NodeB from the non-serving HS_DSCH cell at all, even if the NodeB in the non-serving HS_DSCH cell can learn the corresponding uplink DPCCH transmission slot. In the case where the TPC is generated and transmitted to the UE through the downlink F-DPCH, the TPC transmitted from the NodeB of the non-serving HS_DSCH cell is also not combined.
