Abstract
A method and device for transmitting an uplink signal are provided. The method includes: determining, by a terminal device, a target downlink resource for transmitting a target downlink signal among a plurality of downlink resources; determining, by the terminal device, target uplink pre-coding information according to the target downlink resource and a predetermined corresponding relationship, wherein the predetermined corresponding relationship is a corresponding relationship between downlink resources and uplink pre-coding information; and transmitting, by the terminal device, an uplink signal according to the target uplink pre-coding information.
Claims17
A method for transmitting an uplink signal, comprising:
- determining, by a terminal device, a target downlink resource for transmitting a target downlink signal among a plurality of downlink resources;
- determining, by the terminal device, target uplink pre-coding information according to the target downlink resource and a preset corresponding relationship, wherein the preset corresponding relationship is a corresponding relationship between downlink resources and uplink pre-coding information;
- and
- transmitting, by the terminal device, an uplink signal according to the target uplink pre-coding information;
- wherein the target uplink pre-coding information is used for indicating a target uplink wideband pre-coding matrix;
- or, the target uplink pre-coding information is used for indicating a target uplink beam;
- or, the target uplink pre-coding information is used for indicating a target uplink sounding signal, and the target uplink sounding signal is used for the terminal device to determine a target uplink wideband pre-coding matrix or a target uplink beam.
A terminal device, comprising a processor and a transceiver, wherein,
- the processor is used for determining a target downlink resource for transmitting a target downlink signal among a plurality of downlink resources;
- wherein the processor is further used for determining target uplink pre-coding information according to the target downlink resource and a preset corresponding relationship, wherein the preset corresponding relationship is a corresponding relationship between downlink resources and uplink pre-coding information;
- and
- the transceiver is used for transmitting an uplink signal according to the target uplink pre-coding informatiom;
- wherein the target uplink pre-coding information is used for indicating a target uplink wideband pre-coding matrix;
- or, the target uplink pre-coding information is used for indicating a target uplink beam;
- or, the target uplink pre-coding information is used for indicating a target uplink sounding signal, and the target uplink sounding signal is used for the terminal device to determine a target uplink wideband pre-coding matrix or a target uplink beam.
A network device, comprising a processor and a transceiver, wherein,
- the transceiver is used for sending a target downlink signal to a terminal device on a target downlink resource among a plurality of downlink resources;
- and
- the transceiver is further used for receiving an uplink signal sent by the terminal device according to target uplink pre-coding information, wherein the target uplink pre-coding information is determined by the terminal device according to the target downlink resource and a preset corresponding relationship, and the preset corresponding relationship is a corresponding relationship between downlink resources and uplink pre-coding information;
- wherein the target uplink pre-coding information is used for indicating an uplink wideband pre-coding matrix;
- or, the target uplink pre-coding information is used for indicating a target uplink beam;
- or, the target uplink pre-coding information is used for indicating a target uplink sounding signal, and the target uplink sounding signal is used for the terminal device to determine a target uplink wideband pre-coding matrix or a target uplink beam.
