Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] figure 2 A flow chart of a method for CCE resource allocation in a communication system is shown according to one aspect of the present invention. Wherein, the communication system includes: k user equipments, for example, user equipment 11, user equipment 12, ... user equipment 1k; and a resource allocation device. The communication system includes but is not limited to: an LTE system and the like.

[0033] Specifically, in step S01, the resource allocation device determines a predetermined number of multiple user equipments to be allocated to which CCE resources need to be allocated based on the priority of each user equipment. For example, the priority of user equipment 11 is 1; the priority of user equipment 12 is 1.5; ... the priority of user equipment 1k is 1.8, thus, the resource allocation device is based on user equipment 11, user equipment...

Abstract

The invention provides a method and equipment for carrying out CCE (Control Channel Element) resource allocation in a communication system, wherein the equipment determines a preset quantity of user equipment to be allocated and in need of CCE resource allocation firstly on the basis of the priority of each user equipment; next, the equipment marks respective available CCE resources of each user equipment to be allocated on the basis of respective C-RNTI (Cell-Radio Network Temporary Identity) and polymerization grade of the user equipment to be allocated; then the equipment calculates the influence degree of available CCE resources of each user equipment to be allocated on the allocation of available CCE resources of other user equipment to be allocated on the basis of the respective available CCE resource, polymerization grade priority of all the user equipment to be allocated; and finally, the equipment allocates the CCE resources for all the user equipment to be allocated one by one on the basis of the influence degree and the priority. The method and the equipment disclosed by the invention have the advantage that the utilization ratio of the CCE resources and the scheduling ratio of user equipment can be increased.

Description

[0001] This application claims the national priority of the Chinese patent application with application number 201110024464.2 right. technical field [0002] The present invention relates to the communication field, in particular to a method and equipment for CCE resource allocation in a communication system. Background technique [0003] The control channel element (CCE) of the physical downlink control channel (PDCCH) is a resource used for uplink and downlink. When a user equipment (UE) is scheduled for downlink or uplink, the system must allocate CCE resources for it, and in this The data of the PDCCH is transmitted on the CCE resource. Once the CCE resource is occupied by a certain UE, other UEs cannot use it. [0004] At present, most systems use static uplink / downlink CCE resource allocation, and use a first-come-first-served (FCFS) algorithm to solve the problem of CCE conflicts. The most direct solution to the PDCCH dynamic allocation algorithm is to calculate ...
