Abstract: Disclosed are a beam switching method and apparatus, relating to the technical field of wireless communications, and used for reducing beam switching time and reducing the signaling overhead of switching. The method comprises: determining a beam that needs to be switched, and obtaining the beam identifier of a switched beam and physical random access channel (PRACH) resource indication information; and after the switching of the beam is completed, transmitting, to a network device on the time frequency resource of the switched beam indicated by the PRACH resource indication information, a PRACH signal used for indicating that the switching of the beam is completed. By means of the beam switching method, a beam switching process does not need to transmit an RRC signaling to the network device, and does not need to wait to establish an RRC connection with the network device, thereby being capable of reducing the beam switching time and simultaneously reducing the signaling overhead of switching.

Abstract: Disclosed in embodiments of the present application are a resource allocation method, a device, and a medium. The method comprises: a terminal device determines N NPRACH transmission resources corresponding to a sending period of an ephemeris-bearing SIB bearing according to said sending period as well as configuration information for an NPRACH transmission resource indicated in an SIB2, where N is a natural number greater than zero; the terminal device randomly selects one NPRACH transmission resource from among the N NPRACH transmission resources; and the terminal device performs random access on a network device by means of the selected NPRACH transmission resource. By means of the present method, a terminal can randomly select one transmission resource to perform random access from among a plurality of available transmission resources, causing randomly delayed sending when the terminal performs random access, allowing for dispersion among different transmission resources, the probability of a collision is lowered, and the problem of random access failure caused by a transmission resource sending collision due to terminals initiating random access on a same transmission resource is effectively prevented.

Abstract: A method and apparatus for transmitting downlink control information. In the present invention, transmitted downlink control information at least comprises one or more of the following information fields: a first information field used for indicating the frequency domain resources occupied by the data resources scheduled by the DCI, a second information field used for indicating the time frequency resources occupied by the data resources scheduled by the DCI, and a third information field used for indicating the scheduled N users. As the resource size occupied by the transmission resources in the frequency domain and/or in the time domain is indicated by means of the downlink control information, transmission of downlink control information can be implemented in flexible resource allocation scenarios having variable transmission time intervals.
