Abstract
Embodiments of this disclosure provide a method for PUCCH transmission, a method for PUCCH reception, a terminal, and a network side device. The method for PUCCH transmission is applied to the terminal and includes: transmitting a first PUCCH of at least one cell by using determined spatial relation information after transmitting a beam failure recovery request message to a network side, where the at least one cell includes: a primary cell and at least one secondary cell, or at least one secondary cell.
Claims20
A method for physical uplink control channel (PUCCH) reception, comprising:
- within a first preset period of time, receiving, by a network-side device, a first PUCCH of at least one of a plurality of cells by using determined spatial relation information after receiving a beam failure recovery request message transmitted by a terminal, wherein the plurality of cells comprises:
- a primary cell and a plurality of secondary cells;
- wherein the primary cell is a Primary cell (PCell) of a master cell group (MCG) or a Primary secondary cell (PSCell) of a secondary cell group (SCG);
- wherein each secondary cell is a secondary cell (Scell) other than the PSCell;
- wherein receiving the beam failure recovery request message transmitted by the terminal comprises:
- receiving, by the network-side device, the beam failure recovery request message from the terminal by using a media access control control element (MAC CE);
- wherein the determined spatial relation information is derived based on a preset reference signal in a first preset cell;
- wherein the preset reference signal is a channel state information reference signal (CSI-RS) or a synchronization signal block (SSB), and the first preset cell is a secondary cell with a beam failure in the plurality of cells;
- wherein the first preset period of time starts from:
- when first preset duration elapses after a first preset condition is satisfied, and the first preset duration is F symbols;
- wherein the first preset condition comprises that downlink control information (DCI) transmitted by the network side is received in a second preset cell in the plurality of cells.

- wherein receiving the beam failure recovery request message transmitted by the terminal comprises:
- receiving the beam failure recovery request message from the terminal by using a media access control control element (MAC CE);
- wherein the determined spatial relation information is derived based on a preset reference signal in a first preset cell;
- wherein the preset reference signal is a channel state information reference signal (CSI-RS) or a synchronization signal block (SSB), and the first preset cell is a secondary cell with a beam failure in the plurality of cells;
- wherein the first preset period of time starts from:
- when first preset duration elapses after a first preset condition is satisfied, and the first preset duration is F symbols;
- wherein the first preset condition comprises that downlink control information (DCI) transmitted by the network side is received in a second preset cell in the plurality of cells.
