Disclosed are techniques for wireless positioning. In an aspect, a reduced- capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.

The present invention relates to a method for alignment of a first node with at least one secondary node in a wireless communication network. The first node includes first node antenna beams with corresponding designated pointing angles.

This application provides communication methods for a terminal device and a network side device. In an example method, a terminal device establishes a primary communication link with a network side device. The terminal device detects one or more other terminal devices, determines, from the one or more other terminal devices, one or more terminal devices as one or more coordinated communication devices, and notifies the network side device of information indicating that a coordinated communication device is used for coordinated communication. The terminal device establishes a device-to-device (D2D)-based virtual multiple-input-multiple-output (MIMO) communication connection with the coordinated communication device, to form, between the terminal device and the network side device, a coordinated communication link relayed by the coordinated communication device. The terminal device performs parallel communication with the network side device based on the primary communication link and the coordinated communication link, or performs communication based on the coordinated communication link.
