Abstract: An apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: determine a first allocation comprising at least one of: a first time-domain allocation comprising at least one symbol within a slot associated with a first reference signal transmission, or a first frequency-domain allocation comprising at least one subcarrier within a physical resource block associated with the first reference signal transmission, or a first code-domain allocation comprising a sequence associated with the first reference signal transmission, or a first space-domain allocation comprising a beam associated with the first reference signal transmission; and determine a physical sidelink feedback channel transmission resource for a physical sidelink feedback channel transmission in response to the first reference signal transmission at least based on the determined first allocation.

Abstract: Embodiments of the present disclosure relate to sidelink positioning session establishment. In an aspect, a terminal device obtains session information associated with a first sidelink positioning session, and determines, based on the session information, difference information between the first sidelink positioning session and a second sidelink positioning session in which the terminal device is a target device. The terminal device transmits a positioning request for determining at least one anchor device to perform the second sidelink positioning session, wherein the positioning request comprises the difference information. The terminal device performs the second sidelink positioning session with the at least one anchor device. The embodiments of the present disclosure can immediately activate the target device in an efficient manner with reduced signaling overhead and latency.

Abstract: The disclosure relates to an apparatus comprising: means for determining (1100), by a sidelink manager, a first resource allocation used by a first module for performing sidelink communications via a first radio access technology; means for determining (1102), by the sidelink manager, a second resource allocation used by a second module for performing sidelink communications via a second radio access technology; means for determining (1104), by the sidelink manager, a resource allocation conflict based on the first resource allocation and the second resource allocation; means for converting (1106), by the sidelink manager, the first resource allocation into a converted first resource allocation compatible with the second radio access technology or the second resource allocation into a converted second resource allocation compatible with the first radio access technology; and means for sending (1108), by the sidelink manager, the converted first resource allocation to the second module or the converted second resource allocation to the first module.

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.

Abstract: An apparatus including at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: determine a transmit beam or a time-domain resource associated with a sidelink transmission; and determine at least one physical sidelink feedback channel transmission symbol within a slot for a physical sidelink feedback channel transmission in response to the sidelink transmission at least based on the determined transmit beam or time-domain resource.
