摘要： Provided are signal sending method and apparatus, and a computer storage medium. The method includes: sending a reference signal on an invalid subframe. The method further includes: in a guard band mode, if a downlink timeslot of a special subframe includes N downlink symbols, determining to send the reference signal on the N downlink symbols. The method further includes:
mapping and spreading a code word on a preset number of subframes or resource units for sending the mapped and spread code word. The method further includes: sending the reference signal on an orthogonal frequency division multiplexing (OFDM) symbol, where a resource element other than a resource element where the reference signal is located on the OFDM symbol is a muting resource element, and no data is mapped or sent on the muting resource element.-

摘要： Disclosed are a data transmission method and apparatus, a search space optimization method and apparatus and a storage medium. The data transmission method includes that a UE sends a random access preamble to a base station and receives a random access response sent by the base station, the UE sends a first request message to the base station, and the UE in a first state receives an uplink grant sent by the base station and sends uplink data to the base station by using the uplink grant, where the first state includes an idle state or an inactive state. The UE can transmit uplink data without entering a connected state so that power consumption of the UE is reduced.

摘要： Provided are a resource allocation method and device, and a storage medium. The method includes: configuring resources for transmission of a physical uplink shared channel of a terminal by means of an uplink resource allocation parameter; and transmitting the uplink resource allocation parameter to the terminal. By means of the method, the device and the storage medium of the present disclosure, a base station configures, through the uplink resource allocation parameter, resources for the transmission of the physical uplink shared channel of the terminal and transmits the uplink resource allocation parameter to the terminal, thus solving the problem in the related art the minimum resource allocation granularity in resource allocation for the PUSCH can only be one physical resource block, and reducing the resource allocation granularity.
