Problems solved by technology

[0024] The above-mentioned TPC sending and receiving mechanism has the following disadvantages: that is, in order to determine the relationship between the TPC and the controlled time slot and code combination transmission channel pair when sending and receiving, it must be realized after complex calculations , so it consumes more computing resources, resulting in lower processing efficiency when sending and receiving TPC

Embodiment Construction

[0061] In one embodiment, such as Figure 4 As shown, it is a schematic flow diagram of a method for transmitting a power control command by a terminal according to the present invention. At this time, the local end is a terminal, and the opposite end is a base station, which belongs to the downlink inner loop power control. The specific implementation steps are as follows:

[0062] In the first step, the total number N of time slot and code combination transmission channel pairs (ie downlink time slot and code combination transmission channel pair, DL time slot and CCTrCH pair) sent by the base station (NodeB) in a subframe DLslot , generating a length N DLslot ×N DLslot The lookup table Table1, and then go to the second step. The specific values ​​of the elements of the lookup table Table1 should be: the lookup table can be regarded as being composed of length N DLslot The sub-tables are cascaded, and the total number of sub-tables is N DLslot . Element 1 to element N o...

Abstract

The invention discloses a power control command transmitting and receiving method and the device thereof. The corresponding relation between a sequence number of a being transmitted or received power control command and a sequence number of a controlled time slot and code combined transmission channel pair can be obtained through a pre-generated search table of the sequence number of the time slot and code combined transmission channel pair or through an updating of the search table at the start time of each frame, so that to transmit the power control command in the time slot which carries the power control command, or to adjust the transmitting power level of the time slot and code combined transmission channel pair according to the obtained corresponding relation to realize the transmitting or receiving of the power control command. The realization of the method and device of the invention are simple and have little calculation, thus increase the processing efficiency of the transmitting or receiving of the power control command.

Description

technical field [0001] The invention relates to a method for sending / receiving a power control command in a TD-SCDMA system, and also relates to a device for sending / receiving a power control command in a TD-SCDMA system. Background technique [0002] TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) is the third generation mobile communication system (3G). Compared with the second generation mobile communication system (2G), the TD-SCDMA system can provide Higher business transmission rate provides users with richer services. [0003] like figure 1 Shown is a schematic diagram of the frame structure in the TD-SCDMA system, the chip rate of the TD-SCDMA system is 1.28Mcps, the length of each radio frame (Radio Frame) is 10ms, and is divided into two subframes (Subframes) with the same structure frame), the length of each subframe is 5ms. Wherein, each subframe includes 7 service time slots (TS0-TS6), and the last transmission of each service time slot is ...
