Embodiment Construction

[0032] The scheduling assistance method provided by the present invention can be implemented on the MAC-HS module. Once a user is scheduled through HSDPA scheduling, it will be scheduled continuously for more than (N+1) times, ensuring that at least 1 uplink TPC command and 2 A downlink TPC command is sent to the opposite end in time, so the TD-SCDMA mobile communication system can operate normally under the condition of completely inheriting the existing power control mode. Among them, N is defined as the subframe number difference between sending HS-SCCH and receiving HS-SICH signal, which is determined by the time slot configuration of HS-SCCH and HS-SICH; K is defined as greater than 0 Any integer of , indicating the number of valid TPC commands.

[0033] Considering the timing relationship between HS-SCCH and HS-SICH channels, if a terminal is continuously scheduled (N+1+K) times, it can be guaranteed that at least K uplink TPC commands and (K+1) downlink TPC commands can...

Abstract

The invention relates to a scheduling method of high-speed downlink packet access power control which is used in a mobile communication system, which includes that: Step 1, allocate the continuous scheduling time T of a terminal with T more than N, wherein T is a natural number, and N is a sub-frame number differential between the shared control channel signal of the high-speed downlink shared channel and the shared indication channel signal of the high-speed downlink shared channel; Step 2, if the current sub-frame number S can be exactly divided by T, or no scheduling information of the terminal is buffered currently, the high-speed media access control module schedules the terminal in terms of the normal scheduling method; if the current sub-frame number S can not be exactly divided by T, or some scheduling information of the terminal is buffered currently, the high-speed media access control module directly schedules the terminal for continuously scheduling the terminal for N+1 times to realize the power control. The invention is easy to be implemented, and is able to make best use of the prior power control module to assist in resolving the scheduling problem of power control.

Description

technical field [0001] The invention relates to a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) mobile communication system, in particular to a scheduling assistance method and system for high-speed downlink packet access (HSDPA) power control in the TD-SCDMA mobile communication system. Background technique [0002] In a code division wireless mobile communication system, fast power control technology is generally used to increase the system capacity and avoid the influence of the near-far effect on the system performance. Conventional services include a pair of uplink channels and downlink channels that are continuously transmitted and received in time. Therefore, it is easy to use the received signal of one channel to quickly control the power of another channel. [0003] like figure 1 As shown, assuming that the uplink is in time slot 1 and the downlink is in time slot 6, if the terminal receives a downlink signal in subframe i, a downlink power con...
