1. A method for beam recovery, applied to a terminal and comprising:
receiving resource(s) configured by a network side; and
reporting information associated with beam recovery by using the resource(s) configured by the network side;
wherein the resource(s) configured by the network side comprise one or more of the following:
a contention-based physical random access channel (PRACH) resource;
a contention-free PRACH resource;
a type-1 or type-2 configured grant physical uplink shared channel (PUSCH) resource;
a dynamically scheduled PUSCH resource;
a PUSCH resource dedicated to beam failure recovery;
a contention-based 2-step random access channel resource;
a contention-free 2-step random access channel resource;
a 2-step random access channel resource dedicated to beam failure recovery;
a physical uplink control channel (PUCCH) resource; or
a PUCCH resource dedicated to beam failure reporting;
wherein the receiving resource(s) configured by a network side comprises one or more of the following:
obtaining a PUSCH resource corresponding to a beam failure recovery procedure and/or a cell to which the PUSCH resource corresponding to the beam failure recovery procedure belongs, wherein the PUSCH resource and/or the cell is indicated by the network side when the network side is configuring the beam failure recovery procedure;
obtaining a contention-based 2-step random access channel resource configured by the network side in a broadcast manner;
obtaining a contention-free 2-step random access channel resource configured by the network side in a broadcast or UE-specific manner;
obtaining a PRACH resource corresponding to a beam failure recovery procedure and/or a cell to which the PRACH resource corresponding to the beam failure recovery procedure belongs, wherein the PRACH resource and/or the cell is indicated by the network side when the network side is configuring the beam failure recovery procedure; or
obtaining a PUCCH resource corresponding to a beam failure recovery procedure and/or a cell to which the PUCCH resource corresponding to the beam failure recovery procedure belongs, wherein the PUCCH resource and/or the cell is indicated by the network side when the network side is configuring the beam failure recovery procedure.
