Problems solved by technology

[0014] However, for high-level UEs configured with multiple transmit antennas, there is no configuration method for uplink control channel transmission based on multiple transmission modes, which cannot fully utilize the advantages of UEs with multiple transmit antennas. Therefore, it is necessary to propose a corresponding According to the technical solution of the system, the base station flexibly configures the UE with multiple transmit antennas to use different modes to transmit the uplink control channel according to the operating status of the system

Embodiment Construction

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0036] For a UE configured with multiple transmitting antennas, the technical solution proposed by the present invention supports two types of uplink control channel transmission modes.

[0037] Mode 1, UE fixedly uses a single antenna port to transmit the uplink control channel, and sends the uplink control channel according to the single antenna port transmission mode introduced in the background technology.

[0038] In mode 2, the UE can use multiple antenna ports to transmit uplink control channels. At this time, according to the num...

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 ...
