example 1

[0085] Figure 6 It is a schematic diagram of resource unit index coding and indication of 12 SLRUs according to the preferred example 1 of the embodiment of the present invention, as shown in Figure 6 As shown, the number of bits indicating the resource index (that is, the number of bits occupied by the resource indication information) is 11. Here, 11 bits are taken as an example for illustration, and the maximum resource allocation granularity supported by the base station is 4 consecutive logical resource units. The minimum resource allocation granularity is one continuous logical resource unit, but it is not limited thereto.

[0086] Suppose the index of 12 consecutive logical resource units is [SLRU 0 ,SLRU 1 ,SLRU 2 ,...,SLRU 11 ], divide 12 continuous logical resource units into M=3 resource allocation units (A 0 , A 1 with A 2 ), each allocation unit contains 4 consecutive logical resource units, such as Figure 6 as shown in a. Secondly, calculate 11-3=8>0, ...

Here, 11 bits are taken as an example for illustration, and the maximum resource allocation granularity and the minimum resource allocation granularity supported by the base station are 4 consecutive logical resource units, but are not limited to this .

[0099] Assume that the index of 64 consecutive logical resource units is [SLRU 0 ,SLRU 1 ,SLRU 2 ,...,SLRU 63 ], divide 64 continuous logical resource units into M=16 resource allocation units (A 0 , A 1 , A 2 ,...,A 15 ), each allocation unit contains 4 consecutive logical resource units. Secondly, calculate 11-16=-50 , A 1 ,...,A 9 ), group 2 also includes 10 resource allocation units (A 6 , A 7 ,...,A 15 ), and there is the same resource allocat...

Abstract

The invention discloses a resource distribution indicating method and a base station. The resource distribution indicating method comprises the following steps: the base station divides a logical resource unit into M resource distribution units; when M is more than P, the base station divides the M resource distribution units into K groups, wherein P is a bit number occupied by resource indicating information, and K is more than and equal to 1 or less than M; and the base station sends the resource indicating information to a terminal, wherein the resource indicating information indicates the group with the resource distribution units distributed for the terminal by the base station and/or the resource distribution units distributed for the terminal by the base station in the group. The invention has the advantages of lower complexity, easy realization and wider resource indicating range.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource allocation indication method and a base station. Background technique [0002] In a wireless communication system using base stations for scheduling control, the scheduling and allocation of all available system resources are performed by the base station, for example, the base station schedules and allocates resources for downlink transmission and resources for uplink transmission by terminals. [0003] During the transmission process, the base station needs to transmit resource allocation messages on the downlink channel. If an unreasonable resource allocation indication method is adopted, the downlink resources of the system will be wasted, thereby reducing the transmission efficiency of the entire system. In different communication systems, the base station may use different methods, different messages or signaling to perform resource indication, for example, in ...
