Problems solved by technology

However, if there are N possible resource allocations for the first user, after allocating resources to the first user, the number of possible resource allocations for the second user will decrease accordingly, and the number of resource allocations for the third user will be less, so if subsequent users still use N b Bit to represent, there will be a lot of redundancy, which will bring some useless signaling burden

Embodiment

[0109]In order to illustrate the method of the invention, an example of the method of the invention is given below. In the given embodiment, the system bandwidth is 2.5 MHz, and there are 150 sub-carriers available for data transmission. According to the current discussion in LTE, if 25 subcarriers are used as a resource allocation basic unit (Resource Unit, RU), then 6 resource units are available for a 2.5 MHz system bandwidth.

[0110] Here, firstly, the distributed (Distributed) resource allocation in uplink SC-FDMA is taken as an example, and an embodiment of the present invention is given. For a system bandwidth of 2.5 MHz, the distributed resource units (RU) available for uplink are shown in FIG. 8 . Each RU includes 25 subcarriers, and the minimum interval between subcarriers in one RU is 6.

[0111] It is assumed here that D(d, k) is a distributed channel resource that can be allocated, where d is the minimum interval between subcarriers in the channel resource, and...

Abstract

The related composite resource allocation method comprises: UE and BS obtains the relation between resource allocation composite logic indication sequence and user allocated channel resource combination; UE obtains the user number contained in current transmitted resource allocation control signaling; BS sends control signaling including all allocated UE mark and logic indication sequence indicating resource allocation combination to UE; UE receives the control signaling, determines the resource combination for UE and serial number of other UE in this group UE ID number, and recognizes the allocated resource from BS. This invention reduces signaling loading and physical resource waste.

Description

technical field [0001] The invention relates to a mobile wireless communication system, in particular to a method for indicating channel resource allocation in an OFDM system or a single-carrier FDMA system. Background technique [0002] Now, the third generation partnership project (referred to as 3GPP) standardization organization has begun to carry out long-term evolution (LTE) of its existing system specifications. According to the current discussion about LTE, Orthogonal Frequency Division Multiplexing (OFDM) technology will be used as the downlink physical layer transmission technology in LTE, and single carrier frequency division multiple access (SC-FDMA for short) will be used as the uplink physical layer transmission technology in LTE. Layer transfer technology. [0003] OFDM technology is essentially a multi-carrier modulation communication technology. Its basic principle is to decompose a high-rate data stream into several low-rate data streams and transmit them ...
