Abstract
Embodiments of this application provide a wireless communications method and device, to improve communication performance in an aspect of PUCCH transmission. The method includes: determining resource or signal indication information; determining, according to the resource or signal indication information, an uplink or downlink signal quasi co-located with a to-be-transmitted physical uplink control channel PUCCH; and sending the to-be-transmitted PUCCH according to a quasi co-location relationship between the to-be-transmitted PUCCH and the uplink or downlink signal.
Claims15
A wireless communications method, comprising:
- obtaining, by a terminal device, resource or signal indication information, comprising:
- determining an obtaining manner of the resource or signal indication information according to a physical uplink control channel (PUCCH) format of a PUCCH, and obtaining the resource or signal indication information according to the determined obtaining manner;
- determining, by the terminal device according to the resource or signal indication information, an uplink or downlink signal quasi co-located with the PUCCH, and determining, by the terminal device according to the resource or signal indication information, a power adjustment value corresponding to a transmit power control (TPC) command for the PUCCH carried in downlink control information (DCI) that is used for scheduling a PDSCH corresponding to the PUCCH, the power adjustment value being an accumulated value, wherein the resource or signal indication information is used for determining a transmit beam of the PUCCH and is further used for determining a current closed-loop power control process, including determining a closed-loop power control process in which the power adjustment value corresponding to the TPC command is accumulated;
- and
- sending, by the terminal device, the PUCCH according to a quasi co-location relationship between the PUCCH and the uplink or downlink signal, comprising:
- when the signal quasi co-located with the PUCCH is an uplink signal, determining a transmit beam of the uplink signal as the transmit beam of the PUCCH, or when the signal quasi co-located with the PUCCH is a downlink signal, determining a receive beam of the downlink signal as the transmit beam of the PUCCH;
- and sending the PUCCH by using the determined transmit beam.
