Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] first, figure 1 An exemplary system implementing the method of the present invention is shown. exist figure 1 In , an exemplary system including one serving base station (SBS) and two non-serving base stations (NSBS) and one user equipment UE is shown. The system may be, for example, a network-based or cooperative MIMO system in which the number of non-serving base stations may be any number. The serving base station is responsible for receiving and storing user data from the core network and forwarding data and control signaling to related non-serving base stations. Another function of the serving base station is to transmit data to the user equipment synchronously with the non-serving base station. The non-serving base station receives data and control signaling from the serving base station to implement data transmission to the user equipment.

Abstract

The invention provides an HARQ retransmission control method executed by a system that a service base station and a plurality of non-service base station serve user equipment at the same time. In the invention, the service base station receives HARQ feedback results from the UE, carries out self-HARQ retransmission control according to the results, does corresponding actions to the non-service base station, and indicates the non-service base station to carry out corresponding HARQ retransmission control.

Description

technical field [0001] The present invention relates to a HARQ retransmission control method, more specifically, to a HARQ retransmission control method performed by a system in which a serving base station and multiple non-serving base stations serve a user equipment UE simultaneously. Background technique [0002] Various companies have proposed network MIMO or cooperative MIMO for future mobile communication systems. In general, based on these strategies, multiple base stations can be configured to serve the same UE, so that the UE can combine multiple transmissions from different base stations to improve transmission efficiency. [0003] During the radio link establishment process, the system selects a base station serving the user equipment. The user equipment performs data interaction with the core network through the base station, and the base station stores, processes and sends downlink data from the core network to the user equipment. At the same time, the base st...
