Abstract

The present invention provides a method for indicating wireless channel resource allocation, indicating a starting position and an ending position of m group(s) distributed to a terminal, and indicating a first RBG and a last RBG for a group containing at least two RBGs; when the group contains one RBG and is not the last one, indicating the RBG contained by the group and a previous RBG of a firstRBG contained by a next group; when the group only contain one RBG and is the last one, indicating the RBG and a virtual RBG; or when the group only contain one RBG and is not the first one, indicating a following RBG of the last RBG contained by a previous group, and the RBG contained by the group; when the group only contain one RBG and is the first one, indicating a virtual RBG and the RBG contained by the group. The invention also provides a corresponding decoding method, a base station and a terminal for the wireless channel resource allocation. According to the invention, no matter whatis a number m of the groups, it is nothing remains but to add one virtual RBG only, such that signalling spending is minimum.

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] The LTE (Long Term Evolution, Long Term Evolution) system adopts a centralized scheduling method of the base station to control the transmission of the Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) of the user terminal (User Equipment, UE). [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 UEs are orthogonal in the frequency domain. The base station indicates the radio channel resources allocated for the PUSCH of a certain UE through an uplink scheduling grant signaling (Uplink Scheduling Grant, UL grant for short). [0004] Uplink channel resource allocation in the LTE system tak...
