Claim of US Patent No. 11,032,836

1. A method for Bandwidth Part, BWP, allocation, comprising:determining BWP difference information corresponding to different parameter sets of a first node to which a BWP needs to be allocated and a second node to which a BWP has been allocated according to a first mapping relationship between different parameter sets and BWP difference information, wherein the BWP allocation needs to be performed for the first node in a time unit corresponding to the second node;
judging whether an allocation condition is satisfied according to the determined BWP difference information and a reliability requirement of a service corresponding to the BWP that needs to be allocated to the first node; and
allocating a BWP to the first node in the time unit corresponding to the second node when the allocation condition is satisfied, wherein the allocation condition comprises some or all of following allocation conditions:
a first allocation condition: a difference value between the BWP that needs to be allocated to the first node and the BWP that has been allocated to the second node is less than a maximum difference value, a reliability level of the service corresponding to the BWP that needs to be allocated to the first node is lower than a threshold, and there are resources matching with the BWP that needs to be allocated to the first node in resources that can be allocated in the time unit corresponding to the second node;
a second allocation condition: the difference value between the BWP that needs to be allocated to the first node and the BWP that has been allocated to the second node is not less than the maximum difference value, the reliability level of the service corresponding to the BWP that needs to be allocated to the first node is not lower than the threshold, and there are resources matching with the BWP that needs to be allocated to the first node and resources corresponding to guard interval information, in resources that can be allocated in the time unit corresponding to the second node;
wherein the maximum difference value is a maximum difference value corresponding to coding configuration information of the first node in the BWP difference information; and the resources corresponding to the guard interval information are resources corresponding to the coding configuration information of the first node in guard interval information corresponding to the different parameters sets of the first node and the second node.
