Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication at a user equipment, including receiving on a physical downlink control channel (PDCCH) during a first PDCCH monitoring occasion a first downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH) for each of at least two component carriers, wherein the DCI includes a counter downlink assignment index (DAI) that indicates a number of scheduled PDSCHs up to a point that the first DCI was received and a total DAI indicating a number of scheduled PDSCHs across the at least two component carriers. The implementations further include transmitting a physical uplink control channel (PUCCH) including a position for hybrid automatic repeat request (HARQ)-Acknowledgement (ACK) bits corresponding to the PDSCH for each of the at least two component carriers. Also included is a corresponding a method, apparatus and computer-readable medium of wireless communication at a base station.

Abstract: Hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback enhancements are disclosed for new radio (NR) unlicensed (NR-U). In the downlink control channel, two sets of identifiers (IDs) may be explicitly or implicitly signaled. The two IDs identify a current set ID and an additional set ID. Where the two IDs match, then the ACK feedback transmitted in the current ACK message will reflect the current transmissions. Otherwise, where the two IDs are different, the additional set ID identifies any previous or different ACK information that should be transmitted for prior transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Some aspects more specifically relate to consistent listen-before-talk (LBT) failure recovery for sidelink communications. In some aspects, a medium access control (MAC) layer may transmit, and a physical (PHY) layer may receive, an indication to perform LBT sensing for one or more resource block sets associated with a consistent LBT failure. The indication to perform LBT sensing may be an indication to perform LBT sensing for sidelink communications without transmitting data. The PHY layer may transmit, and the MAC layer may receive, a result of the LBT sensing. In some aspects, the indication to perform the LBT sensing may be an indication to perform Type 1 LBT sensing or an indication to perform Type 2 LBT sensing, and/or may indicate a quantity of LBT sensing operations to be performed.

Abstract: Techniques related to communication device groups and relaying wireless signaling are disclosed. Some aspects of the disclosure relate to devices and methods for receiving an indication configured to indicate that a first device (e.g., a destination user equipment (UE)) is to monitor: at least one first radio link, and at least one second radio link, for at least one data flow. The first device may receive: a first portion of the at least one data flow including DL data over the at least one first radio link, and/or a second portion of the at least one data flow including relay data over the at least one second radio link. The device may transmit an indication corresponding to at least one of: the DL data or the relay data. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive radio link control (RLC) protocol data units (PDUs) within a receive window. Additionally, the UE may receive an uplink grant indicating a set of resources. Based on the set of resources, the UE may transmit a STATUS PDU including a single field that indicates a sequence number (SN) of a first PDU the UE received but unsuccessfully decoded within the receive window. Alternatively, the UE may transmit STATUS PDU segments based on which PDUs the UE receives and the quantity resources in the uplink grant. In some cases, the UE may transmit a STATUS PDU that includes a first field to indicate an SN of a first PDU the UE received but unsuccessfully decoded within the receive window, and one or more offset fields that indicate SNs of respective PDUs subsequent to the first PDU.

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.

Abstract: Certain aspects of the present disclosure provide techniques for selecting a public land mobile network (PLMN) based on route information. A method that may be performed by a wireless node includes camping on a first cellular network on a first frequency band of one or more first frequency bands associated with a first mobile country code (MCC) of a planned route of the wireless node; detecting a condition with the first cellular network after the camping on the first cellular network; and searching, after detecting the condition, for service on the one or more first frequency bands and one or more second frequency bands associated with a second MCC, wherein the one or more second frequency bands are selected based on the first MCC and the planned route.

Abstract: Methods, systems, and devices for wireless communications are described that provide for full-duplex communications at both a user equipment (UE) and a serving network entity in which the UE, the network entity, or both can dynamically change from full-duplex communications to half-duplex communications. A UE may be configured for full-duplex communications for a set of symbols, and may receive an indication to switch one or more symbols to a half-duplex configuration. The half-duplex configuration may correspond to an indicated half-duplex configuration in which both the network entity and UE operate in the half-duplex configuration, or may correspond to a full-duplex configuration of the network entity in which the UE operates in half-duplex and the network operates in the full-duplex configuration. Signaling that indicates one or more symbols to be switched to the half-duplex configuration may be provided in downlink control information, medium access control signaling, or both.

Abstract: Certain aspects of the present disclosure provide techniques for dynamic adjustment of adaptive reception diversity (ARD). An example method, performed at a user equipment (UE), generally includes receiving configuration information configuring the UE with first resources for receiving at least one downlink signal and second resources for transmitting at least one uplink signal, detecting a conflict between the first resources and the second resources, and dynamically adjusting an adaptive reception diversity (ARD) mode if one or more conditions are met after detecting the conflict.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by an apparatus. A method includes transmitting, to a user equipment (UE), an indication of a first frequency of a first signal and an indication of a second frequency of a backscattered signal corresponding to the first signal; transmitting the first signal; and receiving, from the UE, information encoded in the backscattered signal.
