摘要： Provided are a method and apparatus for sending and receiving feedback information, and a storage medium. The method includes: receiving service data sent by a user equipment (UE); and sending downlink feedback indication (DFI) information corresponding to the service data to the UE. Where the DFI information includes a HARQ ACK/non-acknowledgement NACK indication, and the HARQ ACK/NACK indication is configured for indicating a decoding result of a transport block (TB) and/or a code block group (CBG) in the service data decoded by a base station.

摘要： Provided are an information processing method, apparatus and system. The method includes acquiring first information; and performing contention-based access and transmitting a sounding reference signal (SRS) according to the first information, where the first information includes at least one of the followings: a frame structure, a listen-before-talk (LBT) execution position, a SRS transmission position and dedicated indication signaling. The present disclosure solves a collision problem that occurs when a LBT detection position and a SRS transmission position are both on a last OFDM symbol of a subframe in the related art and achieves effects of improving a probability that a UE accesses a channel and increasing SRS transmission opportunities.

摘要： A spectrum resource allocation method and apparatus are provided. The method includes: determining a resource allocation pattern of nodes according to a preset parameter, wherein the preset parameter comprises at least one of: a starting position of a frequency domain or an offset of the frequency domain, an ending position of the frequency domain, a length of consecutively allocated resources or a size of consecutively allocated clusters, a number of clusters or a number of resource sets, a period T, a number of multiplexing nodes in frequency domain resources, or a number of allocatable resources in a system; and obtaining a corresponding resource allocation indicator value r by the resource allocation pattern determined by at least one of the preset parameters in a preset encoding mode. The resource allocation indicator value r is used for indicating resource position information allocated to a terminal UE.
