Embodiment Construction

[0026] The main idea of ​​the present invention is that grouping and resource allocation of CCEs with different aggregation degrees are carried out according to the maximum CCE aggregation degree, which ensures that the group numbers of the optional aggregation degrees in the L-CCE aggregation degree are unified, and realizes the simplification of the allocation method. The middle of the resource grid is set as a common search area; the resource space is divided into multiple subspaces according to the partition function, which reduces the size of the resource allocation space occupied by specific UE-specific control information, and the resource occupied by UE-specific control information is determined according to the first subspace , then the L-CCE group, and finally the CCE process, which reflects a resource allocation method from coarse-grained to fine-grained.

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the pr...

Abstract

The invention discloses a resource distribution method and system, and a blind detecting method, a base station and a user device. The resource distribution method comprises the following steps: the base station calculates the number of PDCCH concentration groups according to PDCCH occupiable CCE resources in a subframe, wherein the maximum PDCCH concentration class is used as the PDCCH concentration group; the base station sets at least one concentration class group in all the PDCCH concentration class groups as a common search region; by using a space division function according to UE information and common information, the base station determines the PDCCH concentration class group, in which the UE special search region is positioned; and the base station searches the position of the UE special search region in the determined PDCCH concentration group to perform PDCCH resource allocation. The method of the invention can be used to enhance the resource distribution efficiency of PDCCH.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method and system for a long-term evolution downlink control channel, a blind detection method, a base station, and user equipment. Background technique [0002] PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) is a very important downlink physical channel in LTE (Long Term Evolution, long-term evolution) system. This channel transmits downlink control information and can be used for UE (User Equipment, user equipment) The scheduling of PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) and the allocation of occupied resources can also be used to inform the UE of the modulation mode and resources of the related business data on PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) Occupancy status, etc., so as to realize correct reception and decoding of service data by the UE. The number...
