Abstract: Disclosed are a method for positioning, a terminal, and a network-side device, which relate to the technical field of communications and are used to provide a means for positioning in a V2X scenario and simplify a positioning flow in the V2X scenario. In the embodiments of the present application, a first terminal determines position information of a second terminal relative to the first terminal according to received auxiliary positioning information. A means for positioning a peer device by the first terminal in the V2X scenario is provided. With this means, measuring the positions of the first terminal and the second terminal by relying on a plurality of base stations is avoided, thereby further simplifying the flow of positioning the second terminal by the first terminal in the V2X scenario; and the applicability thereof is relatively high.

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: The present application relates to the technical field of communications, and provides a transmission method and apparatus. The method comprises: a network side device determines a number of Demodulation Reference Signal (DMRS) port groups N occupied by downlink transmission data sent to a terminal, N being greater than or equal to 1; the network side device determines, according to the number of the DMRS port groups occupied by the downlink transmission data, a code word transmission mode corresponding to the downlink transmission data; and the network side device performs data processing on the downlink transmission data according to the code word transmission mode, and transmits the processed downlink transmission data by means of transmission points corresponding to the N DMRS port groups. By determining, by means of the number of DMRS port groups actually occupied by a data channel, whether to use single code word transmission or double code word transmission, a more flexible method for determining a code word transmission mode is implemented.
