Problems solved by technology

It can be seen that the capacity of the control channel becomes the bottleneck to increase the number of UEs that can actually be served in the cell under the distributed antenna configuration mode, which limits the improvement of cell performance.

Embodiment approach

[0098] The second implementation of the PHICH on the base station side: the base station performs spreading and scrambling on the PHICH, and maps the spread and scrambled PHICH to time-frequency resources corresponding to the cell ID and CSI-RS configuration identifier for transmission. In this embodiment, the base station first uses the prior art to perform spreading and scrambling processing on the signal sequence transmitted on the PHICH; then performs modulation, layer mapping and other processing on the signal sequence after spreading and scrambling. Afterwards, the base station performs resource mapping on the sequence after the above processing according to formula (13), so as to map each PHICH to the corresponding time-frequency resource (that is, the time-frequency corresponding to the cell ID and CSI-RS configuration identifier used when generating the PHICH resources) to launch on.

Abstract

The invention provides a control channel and reference signal transmitting and receiving method, a base station and a user device. The control channel transmitting method comprises the following steps: generating control channel contents corresponding to a cell identity and a configuration identity for the channel state information reference signal CSI-RS configured for the user device in the cell; and mapping the control channel contents to time frequency resources according to the cell identity and the CSI-RS configuration identity for transmission. According to the technical scheme of the invention, multiple control channels can be generated for one cell to improve the capacity of the control channels of the cell, thereby increasing the number of UE which can be really served in the cell and enhancing the service performance of the cell.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular, to a method for transmitting and receiving a control channel, a method for transmitting and receiving a reference signal, a base station, and user equipment. Background technique [0002] The distributed antenna technology allows the base station to be divided into two parts: a wireless baseband control (Radio Server; referred to as: RS) and a remote radio head (Remote Radio Head; referred to as: RRH). User Equipment (referred to as: UE) distance, reduce path loss, expand coverage, improve system performance and other advantages. In 3GPP's advanced long-term evolution (Long Term Evolution-Advanced; referred to as: LTE-A) Rel11 Coordinated Multiple Point Transmission and Reception (abbreviated as: CoMP) technology, the distributed antenna technology is used. Several low-power RRHs are configured in the coverage area of ​​the macro cell. These RRHs hav...
