Abstract: A method of wireless communications by a sidelink UE (user equipment) includes receiving a first signal as part of a discontinuous reception (DRX) wake-up procedure at the beginning of a sidelink discontinuous reception (DRX) ON duration. The method also includes transmitting a response to the first signal as part of a DRX wake-up procedure. The method further includes starting a timer after sending the response. The method still further includes entering a sleep state upon not receiving a physical sidelink control channel (PSCCH) or physical sidelink shared channel (PSSCH) before the timer expires.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless serving node may determine mobility history information associated with the wireless serving node, wherein the mobility history information is associated with a relative mobility between the wireless serving node and one or more reported cells; and transmit, to a child node of the wireless serving node, the mobility history information associated with the wireless serving node. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating symbol extension and windowing for beam switching are disclosed herein. An example method for wireless communication at transmitter includes performing a beam change for communicating with a wireless communication device. The example method also includes extending a transmission for an extended period of time based on the beam change. Additionally, the method includes applying a windowing function to the transmission during the extended period of time.

Abstract: A configuration to enable a UE to transmit an enhanced preamble to initiate a RACH procedure to improve coverage of PRACH without an excessive increase in usage of PRACH resources. The apparatus transmits, to a base station, a preamble to initiate a RACH procedure. The apparatus monitors for at least one RAR, from the base station, during a RAR window in response to the transmitted preamble. The apparatus transmits, to the base station, an enhanced preamble to initiate the RACH procedure if the at least one RAR is not received during the RAR window.

Abstract: Aspects presented herein may enable an IAB node to modify a resource allocation or change one or more parameters related to the resource allocation when the IAB node detects that the resource allocation overlaps with guard symbols or another resource allocation. In one aspect, an IAB node determines that a first channel allocation will be punctured based on an overlap of the first channel allocation with at least one of a guard symbol or a second channel allocation. The IAB node uses, for the first channel allocation or the second channel allocation, one or more of a modified parameter or a modified grant in response to determining that the first channel allocation will be punctured.

Abstract: This disclosure provides methods, devices and systems for handling a reception when another scheduled transmission is canceled. In an aspect, a user equipment (UE) may receive a message from a base station scheduling a first reception for the UE on first resources. The UE may receive a first indicator scheduling a first transmission from the UE on second resources that at least partially overlap with the first resources. The UE may receive a second indicator cancelling the first transmission in a region that partially or fully overlaps the second resources. The UE may determine whether to receive the first reception on the first resources. The UE may transmit an acknowledgment indicating a reception status of the first reception in response to determining to receive the first reception. The base station may determine whether the acknowledgment indicates a reception status of the first reception.

Abstract: An integrated access and backhaul (IAB) node may transition between use of a mobile termination (MT) function at the wireless device and use of a distributed unit (DU) function. The IAB node may schedule communication using the DU function of the wireless device based on whether one or more guard symbols are provided for an allocation from a parent node for the MT function.

Abstract: Aspects relate to implementing a non-dropping rule for mini-slot based repetition of downlink channel data or control. In one example, cancelled repetition may be identified, non-cancelled remaining repetitions may be received, and acknowledgment feedback based on reception results may be generated. In another example, a plurality of time domain resource allocation (TDRA) candidate occasions may be identified where each occasion occurs within a different respective one of a plurality of mini-slots, each mini-slot carrying a different respective one of a plurality of downlink channel repetitions. A TDRA table may be maintained. The TDRA table may include TDRA entries such as location information of the plurality of TDRA candidate occasions associated with the plurality of downlink channel repetitions. The TDRA table may be maintained when at least one of the plurality of downlink channel repetitions is not decoded. A wireless communication device may refrain from dropping non-decoded downlink channel repetitions.

Abstract: Aspects presented herein may enable a UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a first UE or a second UE transmits or receives a relay request of the first UE via sidelink, the first UE being in an RRC connected mode with a base station. The first UE or the second UE receives or transmits, via the sidelink, an indication of relay availability of a second UE in an RRC inactive mode in response to the relay request. The first UE and the second UE receive a configuration from the base station for relay of communication from the base station over the sidelink between the first UE and the second UE.
