Problems solved by technology

[0005] The inventor found in the process of researching the prior art that since the PUSCH is shared by all active UEs under the base station, when multiple UEs simultaneously use the same idle resource in the PUSCH at a certain moment, a resource conflict will occur. In turn, the data sent by multiple UEs interfere with each other, resulting in data transmission failure

Abstract

The invention discloses a data transmission method which comprises the following steps receiving group allocation information transmitted by a base station, wherein, the group allocation information carries group identification of a user group and positional information of user equipment in the user group; detecting a physical downlink control channel according to the group identification so as to acquire idle resource group information in a physical uplink share channel (PUSCH); acquiring idle resource information corresponding to the positional information of the user equipment in the user group from the idle resource group information; transmitting data to the base station by using the acquired idle resource. The method provided in the invention enables the probability of resource conflict occurring when the user equipment transmits data by using the PUSCH to be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a data transmission method, user equipment and a base station. Background technique [0002] The enhanced Long Term Evolution Advanced (LTE-A) system uses carrier aggregation (Carrier Aggregation, CA) technology to expand the system bandwidth. Carrier aggregation mainly aggregates multiple component carriers (Component Carrier, CC) into a high bandwidth Carrier at 20MHz, thus supporting high-speed data transmission. [0003] Compared with the user equipment (User Equipment, UE) working on a single carrier, the UE working under the carrier aggregation needs to feed back more messages to the base station, and the messages that the UE needs to feed back to the base station include scheduling requests (Scheduling Request, SR ), channel quality indicator (Channel Quality Indicator, CQI), acknowledgment (Acknowledge, ACK) and non-acknowledgment (Non-Acknowledge,...
