摘要： Apparatuses, methods, and systems are disclosed for determining channel statistics for clear channel assessments. One method includes determining, by an apparatus, channel statistics corresponding to a plurality of listen-before-talk channel access types, a plurality of channel access priorities, a plurality of frequency ranges, or some combination thereof. The channel statistics indicate whether clear channel assessments for transmission on a shared resource are successful. The method includes transmitting information corresponding to the channel statistics to a network device.

摘要： Apparatuses, methods, and systems are disclosed for determining uplink grants for multiple modes. One method (600) includes determining (602), over a first time period, a first mode uplink grant corresponding to a first mode. Determining the first mode uplink grant comprises receiving the first mode uplink grant. The method (600) includes determining (604) autonomously, over a second time period, a second mode uplink grant corresponding to a second mode. The second mode is different from the first mode. The method (600) includes using (606) the first mode uplink grant and the second mode uplink grant to transmit data based on an uplink grant availability corresponding to the first mode uplink grant and the second mode uplink grant.

摘要： Apparatuses, methods, and systems are disclosed for determining channel statistics for clear channel assessments. One method (900) includes determining (902), by an apparatus (102), channel statistics corresponding to a plurality of listen-before-talk channel access types, a plurality of channel access priorities, a plurality of frequency ranges, or some combination thereof. The channel statistics indicate whether clear channel assessments for transmission on a shared resource are successful. The method (900) includes transmitting (904) information corresponding to the channel statistics to a network device.

摘要： Apparatuses, methods, and systems are disclosed for sidelink communication using multiple protocol stacks. One method (800) includes assigning (802) a first protocol stack of a device to net-work communications. The method (800) includes assigning (804) a second protocol stack of the device to sidelink communications. The method (800) includes generating (806), at the second protocol stack, first information based on arrival of data in a sidelink logical channel. The method (800) includes transmitting (808) the first information from the second protocol stack to a network device via the first protocol stack.

摘要： Apparatuses, methods, and systems are disclosed for sidelink data packet acknowledgment. One method (700) includes receiving (702) an indicator in sidelink control information. The method (700) includes comparing (704) a current value of the indicator to a last known value of the indicator. The method (700) includes, in response to the current value not matching the last known value: flushing (706) a soft buffer; transferring a data packet corresponding to the indicator into the soft buffer; attempting to decode the data packet; in response to successfully decoding the data packet, performing an acknowledgment action; and, in response to unsuccessfully decoding the data packet, performing a non-acknowledgment action.

摘要： Method and apparatus for communication in an Integrated Access and Backhaul (IAB) system with buffer status report (BSR) are disclosed. The apparatus include a receiver that receives a BSR indicating that data is expected to be received; a processor that calculates a first type of buffer size based on the received BSR indicating that data is expected to be received and/or a second type of buffer size based on data presently stored in a buffer; and a transmitter that transmits a buffer status comprising the first type of buffer size and/or the second type of buffer size.

摘要： Apparatuses, methods, and systems are disclosed for integrated access and backhaul node configuration. One method includes receiving, at a first integrated access and backhaul node, a resource configuration corresponding to a second integrated access and backhaul node, wherein the resource configuration comprises information indicating soft resources. The method includes obtaining an activation parameter corresponding to the second integrated access and backhaul node, wherein the activation parameter comprises a first value, a second value, or a combination thereof. The method includes determining whether the activation parameter comprises the first value. The method includes transmitting an availability indication message corresponding to a subset of the soft resources in response to determining that the activation parameter comprises the first value.
