Abstract: A system and a method are disclosed for beam pairing. In some embodiments, the method includes: accessing, by a first User Equipment (UE), configuration data indicating a slot structure including a plurality of resources for transmissions in different directions; and based on the configuration data, transmitting, by the first UE, in a single slot, a first transmission portion using a first resource of the plurality of resources with a first beam direction and a second transmission portion using a second resource of the plurality of resources with a second beam direction, different from the first beam direction.

Abstract: A system and a method are disclosed for network energy saving. In one embodiment the method includes: receiving, by a User Equipment (UE), a Channel State Information reference signal (CSI-RS) transmitted through a first plurality of antenna ports; generating, by the UE, a first channel property indicator for a first subset of the first plurality of antenna ports, based on the CSI-RS; and generating, by the UE, a second channel property indicator for a second subset of the first plurality of antenna ports, based on the CSI-RS, wherein the second subset is different from the first subset.

Abstract: An apparatus and a method are disclosed for SL communication over an unlicensed band by utilizing a frequency interlaced design. A method performed by a UT includes determining whether the UE is operating in a localized mode or an interlaced mode for SL communication, and in response to determining that the LE is operating in the interlaced mode, decoding first stage SCI of a PSCCH based on an interlaced mapping scheme, decoding second stage SCI of a PSSCH based on the decoded first stage SCI, and decoding the PSSCH based on the decoded first and second stage SCI.

Abstract: A device may perform a transmission that may occupy at least a portion of a first slot and perform a listen-before-talk (LBT) sensing operation, wherein the LBT sensing operation may occupy at least a portion of an LBT gap, and at least a portion of the LBT gap may occupy at least a portion of a second slot. A device may perform a transmission that may occupy at least a portion of a first slot, transmit an indication of a resource for an LBT sensing operation, perform an LBT sensing operation for the transmission that may occupy at least a portion of a second slot, and transmit, based on the LBT sensing operation, a reservation signal that may occupy at least a portion of the second slot. A device select a resource for a transmission using a sidelink channel, and select a resource for an LBT sensing operation.

Abstract: A system and a method in a wireless communication network are disclosed to reduce a power consumption of a Multicast and Broadcast Services (MBS) device. The device includes an interface to the wireless communication network that receives wireless communications from the wireless communication network, and a controller. The controller controls the interface to receive unicast communications in a bandwidth part (BWP) of the wireless communication network and to receive MBS communications in a common frequency resource (CFR) of the wireless communications. The controller further controls the interface by selectively receiving MBS communications in the CFR to reduce a frequency bandwidth of the interface, or a combination thereof, to reduce a power consumption of the device.
