Embodiment 1

[0114] The system bandwidth is 5MHz, 25RB. Divide 25RB into two clusters, RBG size is 2RB or 1RB, there are 13 RBGs in total, the 1st to 12th RBG each contain 2RB, the 13th RBG contains 1 RB, each cluster contains 1, 2 or 3 RBG. Such as Figure 9 shown. The constructed resource allocation table is shown in Table 3.

Abstract

The invention discloses a method for indicating wireless channel resource allocation, a base station, a decoding method and a terminal, which can indicate resource positions and save signaling and are used for solving the problem that how to guarantee channel resource indication and signaling overhead in discontinuous resource allocation. The method comprises that: the base station enumerates the number and positions of resource block groups (RBG) possibly contained by each cluster in advance according to the system bandwidth, cluster number and the sizes of the RBG, and identifies each kind of combination of number and positions with unique state flag information; the base station and the terminal agree on the RBG number and positions indicated by each piece of state flag information; and in the process that the base station allocates resources to the terminal, the base station forms a state flag information group by the state flag information corresponding to each cluster of resources and sends the state flag information group to the terminal after determining each cluster of resources to be allocated to the terminal, namely RBG number and positions in each cluster.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for indicating wireless channel resource allocation, a base station, a decoding method and a terminal. Background technique [0002] An LTE (Long Term Evolution, long term evolution) system adopts a centralized scheduling method of a base station to control the transmission of a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) of a user terminal (User Equipment, terminal). [0003] In the LTE system, the PUSCHs of multiple user terminals in a cell are frequency-division multiplexed to the uplink system bandwidth, that is, the PUSCHs of different terminals are orthogonal in the frequency domain. The base station indicates the radio channel resource allocated for the PUSCH of a certain terminal through an uplink scheduling grant signaling (Uplink Scheduling Grant, UL grant for short). [0004] Uplink channel resource allocation in the LTE ...
