Embodiment 1

[0026] Embodiment 1 of the present invention provides a relay-based two-way communication method, such as figure 2 As shown, it is a schematic flowchart of the relay-based two-way communication method described in Embodiment 1 of the present invention, and the method may include the following steps:

[0027] Step 201: The base station acquires channel parameters between the terminal and the base station, between the terminal and the relay, and between the base station and the relay; wherein, the base station is a full-duplex base station, the terminal is a half-duplex terminal, and the The trunk is a half-duplex trunk.

[0028] That is to say, the technical solutions described in the embodiments of the present invention are applicable to a system composed of a full-duplex base station, a half-duplex relay, and a half-duplex terminal. In addition, it should be noted that since a relay can also be regarded as a special type of terminal, the technical solution described in this...

Embodiment 2

[0081] Based on the same inventive concept as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a full-duplex base station. For the specific implementation of the base station, refer to the relevant descriptions in Embodiment 1. Figure 6 As shown, it is a schematic structural diagram of the base station according to Embodiment 2 of the present invention, and the base station may include:

[0082] The acquiring unit 61 is configured to acquire channel parameters between the terminal and the base station, between the terminal and the relay, and between the base station and the relay; wherein, the terminal is a half-duplex terminal, and the relay is a half-duplex medium following;

[0083] The processing unit 62 may be configured to, according to the channel parameters acquired by the acquiring unit 61, select from various settings including direct transmission, relay bidirectional decoding and forwarding transmission, relay downlink d...

Abstract

The invention discloses a bidirectional communication method and device based on relay. According to the technical schemes, a full-duplex base station may, according to the channel parameters acquired between a half-duplex terminal and a full-duplex base station, between a half-duplex terminal and a half-duplex relay, and between a full-duplex base station and a half-duplex relay, select a communication mode from a plurality of configured sets of bidirectional communication modes including direct transmission, relay bidirectional decoding and forwarding transmission, relay downlink decoding and forwarding transmission, and relay uplink decoding and forwarding transmission, for bidirectional communications without the relay and the terminal supporting the full-duplex mode, therefore, reducing the implementation complexity of the relay and the terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a relay-based two-way communication method and equipment. Background technique [0002] At present, wireless relay technology has been widely adopted in standards such as 3GPP LTE-Advanced, IEEE 802.11j, and IEEE802.11m, so that relay nodes can be applied to various communication scenarios. [0003] For example, if figure 1 As shown, the relay can be applied to a full-duplex cell scenario. Specifically, in the relay-based full-duplex cell scenario, since the relay can implement bidirectional transmission of two data streams, a higher frequency utilization rate can be obtained. [0004] However, in this scenario, it is required that the base station (Base Station, BS), the relay station (Relay Station, RS), and the terminal (Mobile Station, MS) all have full-duplex capability, that is, the base station, the relay station, and the Relay-based two-way commu...
