1. A method for determining beam information comprising:
determining, by user equipment based on configuration information of a target communication resource, first information of a source reference signal in a cell and/or bandwidth part (BWP) in which the target communication resource is located, wherein the source reference signal is associated with the target communication resource and is located in a different cell and/or BWP from the target communication resource; and
determining, by the user equipment, beam information of the target communication resource based on the first information;
wherein the first information comprises resource information of the source reference signal in the cell and/or BWP in which the target communication resource is located, and the configuration information comprises a resource quantity A and a resource start position B that are of the source reference signal; and the determining, based on configuration information of a target communication resource, first information of a source reference signal in a cell and/or bandwidth part (BWP) in which the target communication resource is located comprises:
if B is less than a resource start position Nstart of the cell and/or BWP in which the target communication resource is located, determining a resource start position C of the source reference signal in the cell and/or BWP in which the target communication resource is located to be equal to Nstart; otherwise, determining C to be equal to B; and
if A is greater than S+Nstart−C, determining a quantity D of resources of the source reference signal in the cell and/or BWP in which the target communication resource is located to be S+Nstart−C; otherwise, determining D to be equal to A, wherein S is a quantity of resources of the cell and/or BWP in which the target communication resource is located.
