1. A method for physical uplink control channel (PUCCH) transmission, applied to a terminal and comprising:
within a first preset period of time, transmitting a first PUCCH of at least one of a plurality of cells by using determined spatial relation information after transmitting a beam failure recovery request message to a network side, 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 the transmitting, by the terminal, the beam failure recovery request message to the network side comprises:
transmitting, by the terminal, the beam failure recovery request message to the network side 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 K symbols;
wherein the first preset condition comprises downlink control information DCI transmitted by the network side is received in a second preset cell in the plurality of cells.
