Abstract: Embodiments of the present disclosure relate to beam reporting. In an aspect, a first terminal device determines usability of at least one of a plurality of beams associated with at least one reference signal transmitted by a second terminal device based on measured signal level and/or quality; carries out beam-wise comparison among the at least one of the plurality of the beams determined usable, wherein the beam-wise comparison is based on the measured signal level and/or quality for identifying at least one beam having most suitable signal level and/or quality for signal transmission, and transmits, to the second terminal device, an indication indicating at least one of the following: the at least one beam having the most suitable signal level and/or quality; or the at least one of the plurality of beams being usable. The embodiments of the present disclosure can cause fast beam reporting.

Abstract: Embodiments of the present disclosure relate to a method, device, apparatus and computer readable medium for sidelink transmission. According to embodiments of the present disclosure, a first device determines a target transmission start position from a set of candidate transmission starting positions in a sidelink slot based on an access level of a sidelink transmission to be performed. The first device performs a LBT before the target transmission starting position. If the LBT is successful, the first device performs the sidelink transmission from the target transmission starting position. In this way, it enables the use on Mode 2 in shared/unlicensed spectrum, while addressing the issues of un-sensed (not detected) SPS transmissions due to LBT failure as well as making mode 2 more robust towards LBT failures due to other coexisting systems.

Abstract: Systems, methods, apparatuses, and computer program products for handling NR slot aggregation in radio SL co-channel coexistence. A method may include determining that one or more slots of a first radio access technology overlaps a subframe of a second radio access technology. The method may also include detecting whether the second radio access technology is using the subframe of the second radio access technology. The method may further include determining by an outcome of at least one evaluated condition whether to transmit in the one or more overlapping slots or refrain to transmit in the one or more overlapping slots. The method may further include performing transmission with a same transmit power in all the slots that overlap the subframe of the second radio access technology.
