Method and device for transmitting uplink control channel

Abstract

The embodiment of the invention provides a method for transmitting an uplink control channel. The method comprises the following steps that: a base station configures a transmission mode of the uplink control channel of user equipment (UE) through a high-level signaling; and the base station receives the uplink control channel transmitted by the UE through transmit diversity or the uplink control channel transmitted by the UE through a single-antenna port according to the transmission mode. The embodiment of the invention also provides equipment for implementing the transmission of the uplink control channel. In the technical scheme provided by the embodiment of the invention, the base station flexibly configures different modes for the UE with a plurality of transmission antennae to transmit the uplink control channel according to the operation state of the system, so that the requirements of the system on reliability and efficiency are improved, and the system performance is effectively improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a transmission method and device for an uplink control channel. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of LTE (Long Term Evolution, long-term evolution) system as a 3G system. The goal is to develop 3GPP wireless access technology towards Evolution for high data rate, low latency and optimized packet data applications. The multi-antenna technology of the physical layer has become one of the key technologies of the current mobile communication system. The multi-antenna technology has many advantages, such as using the multiplexing gain of multiple antennas to expand the throughput of the system, and using the diversity gain of multiple antennas to improve system performance. , using ...
