Abstract: Techniques for supplementary sidelink resource configuration in full duplex mode may include a first user equipment (UE) transmitting to a base station an interference report indicating sidelink communication interference. The base station may select a resource pool according to the interference report, where the resource pool includes supplementary sidelink subchannels reserved for receiving sidelink communications and conditionally reserved for transmitting sidelink communications based on the interference report. The base station may transmit, to the first UE or a second UE causing the sidelink communication interference, configuration information indicating the resource pool. Based on the configuration information, the first UE and/or the second UE may perform sidelink communications (with each other or with other UEs) using the supplementary sidelink sub channels.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station via the transceiver, an indication to apply an amplitude drooping based at least in part on an uplink band being adjacent to a downlink band in a full-duplex operation. The UE may transmit, to the base station via the transceiver, an uplink transmission in the uplink band based at least in part on the amplitude drooping. Numerous other aspects are described.

Abstract: In an aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group for a preamble is associated with a downlink receive capability of the UE. In another aspect, a UE and BS perform a RACH procedure whereby a preamble sequence group is associated with a group-specific RA-RNTI that is used to scramble an associated DCI communication. In another aspect, UEs performing a RACH procedure with a BS via different sets of ROs may monitor the same GC-DCI scrambled with a common RA-RNTI. In another aspect, a UE and BS perform a 2-Step RACH procedure whereby a Msg-A payload includes information indicative of a downlink receive capability level associated with the UE.

Abstract: Aspects of the present disclosure include methods and devices for informing a base station of autonomously selected SL resources to allow the base station to adjust the DL transmission to mitigate the degradation of the reception of a DL transmission due to self-interference that overlaps with a SL transmission. A device may be configured to select resources for a SL transmission and to transmit, in an UL transmission to a base station, an indication of the resources selected for the SL transmission. A base station may be configured to receive, in an UL transmission, an indication of resources selected for a SL transmission from a UE, and to transmit, based on the indication of the resources selected for the SL transmission, at least one DL transmission that overlaps in time with the SL transmission.

Abstract: The apparatus may be a UE configured to communicate, in a FD mode, with at least one base station via an unlicensed spectrum; determine to cancel at least one UL transmission corresponding to one or more UL resources, the one or more UL resources corresponding to a LBT procedure; and cancel, based on the determination, the at least one UL transmission corresponding to the one or more UL resources. The apparatus may be a base station configured to communicate, in a FD mode, with one or more UEs via an unlicensed spectrum; determine that a LBT procedure associated with DL scheduling will occur via a set of UL resources; and transmit, to the one or more UEs based on the determination, an indication of a cancelation of one or more UL transmissions during the set of UL resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a user equipment (UE) receives, from a base station (BS), an indication of a first set of resource blocks (RBs) to receive a first downlink (DL) transmission in a time interval, the UE receives, from the BS, an indication of a dynamically allocated second set of RBs to receive a second DL transmission from the BS in the time interval, and the UE alters one or more parameters of a receiver, based on the second set of RBs, when receiving the second DL transmission on the second set of RBs. Altering the one or more parameters may include switching a phase-locked loop (PLL) of the receiver to a center frequency determined based on the second set of RBs.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: A base station may apply a nonlinear precoding to data for MU-MIMO transmission to a set of paired UEs to generate a first set of precoder symbols, and apply a linear precoding to the first set of precoder symbols to generate a second set of precoder symbols using a linear precoding matrix. The base station may normalize the second set of precoder symbols, and scale the second set of precoder symbols, before transmission of the data, using a scaling factor based on one or more of modulation symbols or a channel matrix. The base station may apply the linear precoding to DMRS associated with the data. The base station may transmit the second set of precoder symbols based on the second set of precoder symbols and the DMRS to the set of paired UEs.

Abstract: Aspects relate to mechanisms for wireless communication devices to report sub-band (SB) channel state information (SB-CSI). A UE receives a physical downlink shared channel (PDSCH) transmission from a base station. The UE transmits either an acknowledgement (ACK) transmission or a negative acknowledgement (NACK) transmission to the base station in response to a reception of the PDSCH transmission. The UE determines whether to transmit a sub-band (SB) channel state information (SB-CSI) report to the base station based on whether the ACK transmission is transmitted to the base station or whether the NACK transmission is transmitted to the base station.
