Problems solved by technology

[0005] In the above method of resource allocation indication, the signaling sent by the base station to the user terminal is composed of bits, and the length of the signaling is the sum of the number of bits corresponding to each user terminal. Since the resource information occupied by each user terminal uses the same The number of bits represents the number of bits, so the length of the signaling sent by the base station to the user terminal should be the product of the number of user terminals and the numbe

Embodiment Construction

[0026]Now, the resource allocation indication method and device provided by the present invention will be described in detail with reference to the embodiments and related drawings.

[0027] Taking the downlink direction of signaling sent by the base station to the user as an example, the first embodiment of the resource allocation indication method of the present invention is described.

[0028] As shown in FIG. 4 , in step S401 , the base station sequentially constructs resource information occupied by all centralized user terminals into bitmaps with different numbers of bits. In this step, the base station needs to construct the resource information occupied by all centralized user terminals into a bitmap. Before constructing the bitmap, the base station needs to sort the centralized user terminals, and then according to the resource information occupied by the centralized user terminals Construct a bitmap, the number of bits in the bitmap can vary.

[0029] If the entire ...

Abstract

The invention provides a resource distribution indication method of communication system that comprises: base station constructs the resource information occupied by integrated user terminal to bit graph with different number of bit; said base station forms indication command with all bit graph and resource information occupied by distributed user terminal, and sends said command in sharing mode to all user terminals, or, all user terminals compose command with all bit graph or resource information occupied by user terminal and send it to the base station; all user terminals or said base station demodulate the shared command or said composed command, and demodulate data to corresponding resource based on relative indication information. The invention also provides a resource distribution indicating device of communication system.

Description

technical field [0001] The present invention relates to the communication technology, in particular to the resource allocation indication technology of the communication system. Background technique [0002] In the downlink signaling and data transmission of the physical layer of the 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution) system, a subframe includes 7 consecutive OFDM (Orthogonal Frequency Division Multiplexing (orthogonal frequency division multiplexing) symbols, each symbol includes M data subcarriers, and the value of M can be determined by the bandwidth. In the 3GPP LTE system, a subframe can be regarded as a time-frequency plane, and 7×M modulation symbols can be transmitted in this time-frequency plane. In downlink signaling and data transmission, the base station may transmit data of multiple user terminals at the same time. In this case, resource allocation must be performed among different user terminals. In the cu...
