Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an amount of time between uplink allocations that is needed for performing frequency retuning during operation at a subcarrier spacing (SCS). The UE may perform frequency retuning in association with hopping from a first set of frequency resources, associated with transmitting a first uplink transmission, to a second set of frequency resources, associated with transmitting a second uplink transmission, during operation at the SCS, wherein the frequency retuning is performed during a set of consecutive unallocated resources determined based at least in part on the amount of time between uplink allocations that is needed for performing frequency retuning. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive sounding reference signal (SRS) resource set configuration information that indicates an aperiodic SRS resource set, an aperiodic downlink reference signal resource associated with the aperiodic SRS resource set, and a slot offset associated with the aperiodic downlink reference signal resource. The UE may receive downlink control information indicating that the aperiodic SRS resource set is triggered and determine a quasi co-location assumption for the aperiodic downlink reference signal resource based on the slot offset associated with the aperiodic downlink reference signal resource. The UE may measure the aperiodic downlink reference signal resource in a slot indicated by the slot offset based on the quasi co-location assumption.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of sounding reference signals (SRSs) based at least in part on a mapping configuration, the mapping configuration being associated with mapping the set of SRSs to a set of channel state information reference signals (CSI-RSs) received by the UE, and the set of CSI-RSs being received based at least in part on a set of reception settings, each associated with a respective CSI-RS of the set of CSI-RSs; determine, based at least in part on the set of reception settings, a set of transmission settings, each corresponding to a respective SRS of the set of SRSs; and transmit the set of SRSs based at least in part on the set of transmission settings. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication (PEI) indicating whether at least one UE in a UE group or a UE sub-group including the UE is to be paged in a paging occasion. In some aspects, a sequence on which the PEI is based is a physical downlink control channel (PDCCH)-based sequence. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a sequence configuration configured on the UE. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a distributed resource block allocation associated with the sequence. The UE may selectively process a paging PDCCH associated with the paging occasion based at least in part on the PEI. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (LIE) may select uplink communication resources to be used to transmit enhanced uplink control information (UCI) to a base station based at least in part on a size of a hybrid automatic repeat request (HARQ) codebook and an enhancement number, and transmit the enhanced UCI using the selected uplink communication resources, the enhanced UCI comprising a set of feedback bits and a set of enhancement bits, the set of feedback bits comprising at least one negative acknowledgement (NACK) bit, and wherein the set of enhancement hits indicate information associated with the at least one NACK bit. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiver may receive, from a transmitter, an indication of a signature of a reconfigurable intelligent surface (RIS). The receiver may receive a signal that is transmitted by the transmitter and redirected by the RIS. The receiver may receive, from the RIS, a sequence associated with the signature of the RIS indicating that the signal is transmitted using a link associated with the RIS. Numerous other aspects are described.

Abstract: A first user equipment (UE) that does not support cross-slot scheduling (CSS) and a second UE that supports the CSS may share a paging occasion (PO), and a base station that supports CSS may configure a set of variable K0 greater than zero to the second UE. The base station may page both the first UE and the second UE in the shared PO by transmitting a first paging message for the first UE in the shared PO with K=0, and transmitting a second paging message for the second UE transmitted in the subsequent PO. The first UE may receive a paging scheduling physical downlink control channel (PDCCH) with K0=0 in the shared PO and monitor consecutive POs subsequent to the shared PO to receive the paging message. The base station may also assign separate sets of POs to the CSS-capable UE and the CSS-incapable UE.

Abstract: A method, a computer-readable medium, and an apparatus are disclosed. The apparatus may be a UE. The apparatus may transmit, to a base station, an indication of a UE capability for PDCCH monitoring. The apparatus may configure, based on the UE capability for PDCCH monitoring, first MOs of a USS set to align with second MOs of a CSS set. The apparatus may monitor, based on the configuration, for a plurality of PDCCHs during PDCCH MOs. The PDCCH MOs may correspond to the first MOs or the second MOs. The first MOs of the USS set may be adjusted dynamically to be in same slots as the second MOs of the CSS set or to be within a predefined range of the second MOs of the CSS set.
