Abstract

An embodiment of the present disclosure provides a method performed at a UE for data transmission. The method includes: detecting a scheduling assignment(SA) for other UEs within a sensing window which includes a plurality of time units(TUs); selecting, based on the detected SA, a set of resources for data transmission; determining, before transmitting data on a resource in the selected set of resources, whether the resource is occupied; and transmitting the data on the resource in the selected set of resources if it is determined that the resource is not occupied. An embodiment of the present disclosure also provides a corresponding UE.

Dependent claims

A method for data transmission, comprising:

detecting a scheduling assignment (SA) for other UEs within a sensing window which includes a plurality of time units (TUs);
selecting, based on the detected SA, a set of resources for data transmission;
determining, if the UE does not perform data transmission on one of the selected set of resources, whether a resource subsequent to the one resource in the selected set of resources is occupied based on the detected SA, a received power and a received energy on the resource only in a case where a number of consecutive resources, among the selected set of resources, on which the UE does not perform data transmission exceeds a predetermined threshold NR2, before transmitting data on a resource in the selected set of resources;
and
transmitting the data on the resource in the selected set of resources if it is determined hat the resource is not occupied.

2 more elements

A user equipment (UE), comprising:

a detection unit configured to detect a scheduling assignment (SA) for other UEs within a sensing window which includes a plurality of time units (TUs);
a selection unit configured to select, based on the detected SA, a set of resources for data transmission;
a determination unit configured to determine, if the UE does not perform data transmission on one of the selected set of resources, whether a resource subsequent to the one resource in the selected set of resources is occupied based on the detected SA, a received power and a received energy on the resource only in a case where a number of consecutive resources, among the selected set of resources, on which the UE does not perform data transmission exceeds a predetermined threshold NR2, before transmitting data on a resource in the selected set of resources;
and
a transceiver configured to transmit the data on the resource in the selected set of resources if the determination unit determines that the resource is not occupied.
