Abstract: Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes receiving an indication from a base station (BS) that multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled in all physical uplink control channel (PUCCH) resources, generating a first CSI report regarding a first downlink (DL) channel from the BS, multiplexing a HARQ response to a transmission from the BS and the first CSI report in a PUCCH, and transmitting the PUCCH to the BS via one of the PUCCH resources.

Abstract: Methods, systems, and devices for wireless communications are described that provide for indication of channel state information (CSI) for multiple CSI codebooks associated with multiple different sets of antenna ports, where CSI parameters for one or more of the codebooks are reported as differential values relative to reported values of another of the codebooks. A user equipment (UE) may receive a CSI report configuration that includes a set of CSI resources and multiple codebooks for multiple different sets of antenna ports. The UE may identify a first set of CSI parameters associated with a first codebook, and may identify a second set of CSI parameters associated with a second codebook. The UE may transmit a CSI report that includes the first set of CSI parameters and a set of differential CSI parameters that indicate a difference between the first and second sets of CSI parameters.

Abstract: Aspects of the present disclosure provide techniques of allocating time resources (or slots) based on a flexible pattern that allows allocation of a set of non-continuous time slots resources in an integrated access and backhaul (IAB) system. In one example, the aggregation pattern may be indicated via a single downlink control information (DCI) message that carries explicit information regarding non-continuous time slot allocation. Features of the present disclosure may also include techniques to allow for early termination of transmission between the first node and the second node when the receiver (e.g., second node) successfully receives the data channel before the end of aggregated transmission. In such situation, the first node and the second node may cease transmission after reception of an acknowledgement (ACK) message that may allow the second node to utilize the subsequent time slots for communication with its own children on the next hop (e.g., third node).

Abstract: Techniques are described for wireless communication. One technique includes receiving a service via a component carrier, wherein the component carrier may be in an unlicensed radio frequency spectrum band. One or more signals transmitted on the component carrier may be measured to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band.

Abstract: An apparatus for wireless communication includes a transmitter configured to communicate with a base station based on a first uplink bandwidth part (BWP) that includes a first frequency subset and that further includes a second frequency subset. The apparatus further includes a receiver configured to receive, from the base station, one or more messages including a frequency hopping indicator that specifies whether a frequency hopping mode is enabled or disabled. The transmitter is further configured to transmit, to the base station, an uplink control channel transmission using both the first frequency subset and the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is enabled or using one of the first frequency subset or the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is disabled.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for indicating sidelink CSI information to a base station. A UE and a base station may determine a priority of a sidelink CSI report on an uplink channel in association with a priority of one or more of at least one uplink transmission or at least one other sidelink transmission. The sidelink CSI report may correspond to one or more sidelink transmissions between the UE and at least one other UE. The UE may transmit, and the base station may receive, via the uplink channel, the sidelink CSI report based on the priority of the sidelink CSI report on the uplink channel being determined in association with the priority of the one or more of the at least one uplink transmission or the at least one other SL transmission.

Abstract: Apparatus, methods, and computer-readable media for facilitating multiplexing of downlink grant-triggered aperiodic channel state information reports on an uplink control channel are disclosed herein. An example method for wireless communication at a UE includes receiving scheduling to provide multiple A-CSI reports while foregoing A-CSI multiplexing, the scheduling for up to two A-CSI reports in a same slot for the UE, and the multiple A-CSI reports being non-overlapping in time in the same slot. The example method also includes transmitting the multiple A-CSI reports to a base station in respective PUCCH in the same slot and while foregoing CSI multiplexing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.
