Abstract

The embodiment of the invention, which relates to the communication field, provides a method for uplink cooperation of a cell, and base stations. Therefore, a problem that an uplink rate of the UE is low because combined receiving of demodulation and decoding information can not be carried out due to long data interaction delay between base stations can be solved. The method comprises: a first base station determines whether first uplink data that are sent by UE and are forwarded by a second base station are received before first time; if not, the first base station carries out demodulation and decoding on second uplink data received from the UE; if a wrong demodulation and decoding result is obtained, the first base station enables an HARQ progress to be hanged, whether the first uplink data forwarded by the second base station are received between the first time and second time is determined, wherein the second time is later than the first time; if so, the first base station carries out combined demodulation and decoding on the first uplink data and the second uplink data and determines a demodulation and decoding result. According to the embodiment of the invention, the method is used for demodulation and decoding of UE uplink data by the base stations.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell uplink coordination method and a base station. Background technique [0002] Uplink Coordinated Multiple Points (CoMP) technology is to use multiple sectors in the base station or multiple base stations to jointly receive, demodulate and decode the uplink data of the user equipment (UserEquipment, UE), so as to improve the coverage of the edge UE Performance, the purpose of improving the UE uplink rate. For example, the serving cell of the UE belongs to base station 0, and the coordinated cells belong to base stations 1~K (K≥1), and base station 0 and base stations 1~K jointly receive, demodulate and decode the uplink data sent by the UE. In this mode, after base station 0 completes the MAC layer scheduling, it sends management information (for example, scheduling information for accessing UEs) to base stations 1~K, and then UE sends the same uplink data to...
