Claim of US Patent No. 10,397,918

1. A resource allocation method, comprising:when a physical uplink control channel (PUCCH) format 2x resource needs to be allocated to a user equipment (UE), obtaining a multiplexing degree value of a format 2x resource block (RB) in a current cell to which the UE belongs, selecting a format 2x RB with a lowest multiplexing degree value in the current cell, and when multiple format 2x RBs in the current cell have the lowest multiplexing degree value, selecting one of the multiple format 2x RBs, wherein the multiplexing degree value of the format 2x RB identifies a quantity of used resource indexes on the format 2x RB, wherein the PUCCH format 2x includes a format 2, a format 2a and a format 2b; and
allocating, to the UE, a PUCCH format 2x resource on the selected format 2x RB with the lowest multiplexing degree value, by:
determining whether an available PUCCH format 2x resource exists on an occupied resource index on the selected format 2x RB with the lowest multiplexing degree value; and
when the available PUCCH format 2x resource exists on the occupied resource index on the selected format 2x RB with the lowest multiplexing degree value, allocating a PUCCH format 2x resource on the occupied resource index; and
when no available PUCCH format 2x resource exists on the occupied resource index on the selected format 2x RB with the lowest multiplexing degree value, allocating a PUCCH format 2x resource on an unoccupied resource index on the selected format 2x RB with the lowest multiplexing degree value, by determining a next unoccupied target resource index according to a predetermined distance interval between resource indexes on the selected format 2x RB with the lowest multiplexing degree value, and allocating a PUCCH format 2x resource on the target resource index.
