Abstract: Techniques and apparatus for determining a transport block (TB) configuration and hybrid automatic repeat request (HARQ) acknowledgment (ACK)/negative acknowledgment (NACK) configuration for full duplex (FD) UE(s) are described. One technique involves receiving channel state information (CSI) report(s) from a UE operating in FD mode. At least one of a TB configuration or feedback type for a communication slot is determined based on the CSI report(s). The communication slot can include half duplex (HD) symbol(s) and FD symbol(s). An indication of at least one of the TB configuration or the feedback type is signaled to the UE. Another technique involves receiving, from a base station (BS), downlink data transmission(s) across a slot(s). A type of duplexing mode associated with each of the slot(s) is determined. The downlink data transmission(s) are acknowledged, based at least in part on the type of duplexing mode associated with each of the slot(s).

Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration identifying a first set of frequency resources for transmitting a sounding reference signal, where the sounding reference signal may be used at least for downlink channel state information acquisition. The UE may receive an indication of an association between the configuration for the sounding reference signal and a second set of frequency resources and determine, based on the association, values for one or more sounding reference signal transmission parameters for the first set of frequency resources. The UE may transmit the sounding reference signal on the first set of frequency resources based on the determined one or more values.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to identify a first set of scheduled transmissions to be received using a first set of time-frequency resources, where reference signals of the first set of transmissions may be bundled according to a first reference signal bundling pattern. The UE may identify a second scheduled transmission to be received using a second set of time-frequency resources that overlaps with the first set of resources. The UE may determine a second reference signal bundling pattern for bundling the reference signals received in the first set of transmissions. For example, the UE may modify the first reference signal bundling pattern to determine the second reference signal bundling pattern. The UE may receive the second scheduled transmission and the first set of scheduled transmissions according to the second reference signal bundling pattern.

Abstract: Various aspects of the disclosure relate to use of a default communication configuration for cross carrier wireless communication. For example, a wireless communication device such as a user equipment (UE) may use a default communication configuration that includes quasi-colocation information (e.g., a default CORESET configuration) for communication on a secondary component carrier (SCC). The default communication configuration may be used, for example, in scenarios where a CORESET is not defined for the SCC and other configuration information is not available. For example, other configuration information might not be available due to a short time gap between a grant sent on a primary component carrier (PCC) and the communication on the SCC scheduled by the grant.

Abstract: A UE includes: a transceiver; a memory; and a processor configured to: receive first and second discontinuous reception configurations for first and second discontinuous reception groups; receive first and second positioning signal configurations for first and second positioning signals associated with the first and second discontinuous reception groups, respectively; measure the first positioning signal during a first active time of the first discontinuous reception group; and measure the second positioning signal during a fixed second active time or during a variable third active time, the fixed second active time having a fixed duration of the second discontinuous reception group and the variable third active time having a variable duration of the second discontinuous reception group.

Abstract: A user equipment (UE) is transmits capability signaling information to a base station. The capability signaling information may be associated with a capability of the UE to maintain coherence and bundle demodulation reference signals (DM-RS) when a transmission is interrupted. The base station may receive a transmission from the UE having dropped symbols, may determine if the capability signaling information indicates that the UE maintained coherence over the dropped signals, and may utilize bundled DM-RS to decode the transmission if the capability signaling information indicates that the UE maintained coherence.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide managing transmissions of sidelink positioning reference signals (PRS) with a timing advance offset (TA) from a sidelink node. In aspects, a sidelink node (e.g., a target user equipment (UE) or an assisting UE) may receive transmissions from a plurality of nodes (e.g., target UEs or assisting UEs). The sidelink node obtains at least one TA to be used by a transmitting node of the plurality of nodes for transmitting a sidelink PRS to the sidelink node (e.g., to advance the sidelink PRS transmission to the sidelink node with respect to the timing of the first transmission). The TA is an offset obtained by the sidelink node based on the receiving times of the transmissions from the plurality of nodes. The sidelink node may receive PRS transmissions from the plurality of nodes in a same symbol aligned within the same CP.
