Abstract: This application provides a signal transmission method and apparatus, to help a terminal device determine a receive beam for a positioning reference signal. This can reduce overheads of performing receive beam sweeping by the terminal device, and save resources. The method includes: A terminal device receives a first positioning reference signal PRS resource set and a second PRS resource set that are sent by a network device, and learns that N first PRS resources in the first PRS resource set and N second PRS resources in the second PRS resource set satisfy a quasi-colocation QCL relationship.

Abstract: This application provides example signal transmission methods and example apparatuses. One example method includes receiving random access channel (RACH) configuration information of a neighboring cell from a location management device or a serving cell, where the RACH configuration information includes information about an RACH resource and a preamble. The preamble can then be sent to the neighboring cell by using the RACH resource. An uplink TA of the neighboring cell that is determined by the neighboring cell based on the preamble can then be received.

Abstract: This application discloses a random access method and a communication apparatus, to resolve a problem in an existing technology that UEs interfere with each other in a random access procedure. In this application, a network device separately configures a random access resource used for random access performed when a TA is invalid and a random access resource used for random access performed when the TA is valid, so that UE with the invalid TA and UE with the valid TA use different random access resources to perform random access, thereby reducing mutual interference between the UEs and improving data transmission efficiency. In addition, in this application, the network device separately configures random access resources used by UEs with different TA accuracy levels to perform random access, so that the UEs with different TA accuracy levels use different random access resources to perform random access.

Abstract: Embodiments of this application provide a data transmission method, a network device, and a terminal device. The method may include detecting, by a network device, a first signal in an uplink signal. The method may also include determining, by the network device, a signal structure of the uplink signal based on a result of detecting the first signal. Furthermore, the method may include receiving, by the network device, the uplink signal based on the signal structure, and/or responding to the uplink signal based on the signal structure. According to the data transmission method in the embodiments of this application, before receiving data, the network device can determine the signal structure, used by the terminal device, of the uplink signal, and then use a corresponding receiving method to avoid complexity and a reliability risk that are caused by completely blind detection performed by the network device.

Abstract: This application discloses a communication method and a communications apparatus. User equipment transmits uplink data by using a first transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is less than or equal to a first time interval; or transmits uplink data by using a second transmission parameter set when a time interval from a current moment to a latest moment at which uplink timing information is received is greater than the first time interval, where a transmission parameter included in the first transmission parameter set is different from that included in the second transmission parameter set. Different transmission parameter sets are used to transmit the uplink data at different time intervals based on the time interval from the current moment to the latest moment at which the uplink timing information is received.

Abstract: A method and an apparatus may be used for positioning a terminal device. Positioning measurement information for a terminal device is obtained by using a measurement apparatus on the terminal device side and/or an access node side, where the positioning measurement information is multipath positioning measurement information that is based on a single access node, and includes positioning measurement information of a main path and at least one reflection path that are based on the single access node, or positioning measurement information for at least two reflection paths. The measurement apparatus on the terminal device side and/or the access node side reports the positioning measurement information to a positioning function entity in a network, so that the positioning function entity can perform location estimation on the terminal device based on the positioning measurement information, to position the terminal device.
