US 12,713,272 B2 · Method and device used for relay wireless communication

Abstract

The present application provides a method and device for sidelink wireless communications. A first node receives a first signaling via an air interface; as a response to receiving the first signaling, transmits a first radio signal, the first radio signal comprises a second signaling; receives a second data unit set via an air interface; herein, the second signaling indicates that a first data unit set is not received, and both the first data unit set and the second data unit set are transmitted through a first radio bearer; the second signaling is used to determine the second data unit set; a transmitter of the first signaling is non-co-located with a receiver of the first radio signal; the first data unit set comprises at least one data unit; the second data unit set comprises the first data unit set. The present application can effectively reduce data retransmission.

Dependent claims

A user equipment (UE) for wireless communications, the UE comprising:

a transceiver;
and
a processor, wherein the transceiver and the processor are configured to:
determine, based on first and second reference data volumes, a buffer size for a first logical channel set,
determine that a difference value between the buffer size for the first logical channel set and a first reference buffer size exceeds a first threshold,
generate a first Buffer Status Report (BSR), wherein the first reference buffer size is associated with a second BSR, and wherein the second BSR is a latest BSR reported for the first logical channel set or the second BSR is a latest BSR triggered for the first logical channel set,
transmit a first radio signal carrying the first BSR,
receive a first data unit set through a first channel set,
transmit a second data unit set through a second channel set, wherein any bit in the second data unit set belongs to the first data unit set, and any data unit in the second data unit set is mapped into a logical channel in the first logical channel set.
