1. A beam information determining method, performed by a terminal and comprising:
determining a candidate beam information pool of a first set, wherein the first set comprises at least one downlink channel and at least one uplink channel, or the first set comprises at least one channel and at least one reference signal; and the candidate beam information pool comprises at least one piece of candidate beam information; and
determining, based on the candidate beam information pool, beam information of at least one of a first channel or a first reference signal that are comprised in the first set; wherein
in a case that the candidate beam information pool comprises at least two pieces of candidate beam information, the determining, based on the candidate beam information pool, beam information of the at least one of the first channel or the first reference signal that are comprised in the first set comprises:
receiving first indication information for at least one of the first channel or the first reference signal that are comprised in the first set, the first indication information being used to indicate one piece of candidate beam information in the candidate beam information pool; and
determining the beam information of the at least one of the first channel or the first reference signal based on the first indication information;
wherein the method further comprises:
receiving second indication information for at least one of a third channel or a third reference signal that are comprised in the first set, the second indication information being used to indicate one piece of candidate beam information in the candidate beam information pool;
in a case that an application time of the candidate beam information indicated by the first indication information is a latest application time, determining the beam information of the at least one of the first channel or the first reference signal based on the candidate beam information indicated by the first indication information; and
in a case that the application time of the candidate beam information indicated by the second indication information is the latest application time, determining beam information of at least one of the third channel or the third reference signal based on the candidate beam information indicated by the second indication information.
