Claim of US Patent No. 11,071,134


1. A feedback information receiving method, comprising:determining an uplink subframe for receiving feedback information corresponding to downlink data;
determining a physical uplink control channel (PUCCH) resource;
sending scheduling information for scheduling the downlink data, on a downlink control channel to user equipment, wherein the downlink control channel is in a downlink subframe that belongs to a preconfigured downlink subframe set, and the preconfigured downlink subframe set is a set of downlink subframes that are associated with the uplink subframe and that are of all carriers configured for the user equipment by a base station;
receiving on the PUCCH resource in the uplink subframe, encoded feedback information from the user equipment;
wherein the scheduling information comprises PUCCH resource indication information and a downlink assignment index (DAI) accumulation indication, and
the PUCCH resource indication information indicates the PUCCH resource, and a value of the DAI accumulation indication indicates an accumulative counting in a scheduled downlink subframe subset according to an order that is first in ascending order of a carrier index and then in ascending order of a subframe index, and the scheduled downlink subframe subset belongs to the preconfigured downlink subframe set.
