RESOURCE POOL CONFIGURATION METHOD, RESOURCE SELECTION METHOD AND APPARATUS AND COMMUNICATION SYSTEM

摘要

Provided in the embodiment of the present invention are a resource pool configuration method, a resource selection method and apparatus and a communication system. The resource pool configuration method comprises: a first communication apparatus configuring resource pools for a second communication apparatus, wherein within the period and bandwidth of one of the resource pools, resource units do not occupy all physical resource blocks (PRB) in a time-frequency domain; and/or the lengths of cyclic prefixes (CP) used by the resource units being the same within one of the resource pools. Through the use of the method of this embodiment, excellent frequency-domain and time-domain diversities are offered to guarantee average performances in broadcast communications and discoveries on the basis of the feature that the resource units do not occupy all the physical resource blocks (PRB) in the time-frequency domain, and thus a small influence is exerted upon traffic scheduling of a cellular network and also the flexibility thereof is ensured as much as possible; and on the basis of the feature that the lengths of the CPs used by the resource units are the same within the resource pool, the inter-carrier interference and the inter-subchannel interference caused by the different lengths of the CPs used by transmission entities are minimized.
