Abstract: Certain aspects of the present disclosure provide techniques for multiplexing uplink control information (UCI) on physical uplink control channel (PUCCH) resources for non-ideal backhaul based multi-transmission/reception point non-coherent joint transmissions. An example method generally includes determining that a first set of physical uplink control channel (PUCCH) resources configured for reporting channel state information (CSI) overlaps with a second set of PUCCH resources indicated for reporting hybrid automatic repeat request (HARQ) feedback, wherein the first and second sets of PUCCH resources are associated with downlink demodulation reference signal (DMRS) port groups, generating CSI reports and HARQ feedback associated with at least one of the downlink DMRS port groups, and transmitting the CSI reports and the HARQ feedback, multiplexed using the second set of PUCCH resources.

Abstract: During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

The control signaling may comprising an indication of at least one of a set of resources of a sidelink channel available for sidelink communication with a second UE, an indication of a resource allocation mode type for the set of resources, and an indication that the first UE is one of a transmitter or receiver for the set of resources of the sidelink channel. The first UE may receive, from the base station, a sidelink preemption indication indicating that at least a first resource from the set of resources is preempted. The first UE may then communicate a sidelink transmission over the sidelink channel with the second UE based on the sidelink preemption indication and the control signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a set of resources to be used for reception of a synchronization signal block (SSB) overlaps at least one of a set of resources to be used for a first uplink transmission or a set of resources to be used for a second uplink transmission. The set of resources to be used for the first uplink transmission may overlap the set of resources to be used for the second uplink transmission. The first uplink transmission and the second uplink transmission may have a same priority index value. The UE may resolve an overlap between the first uplink transmission and the second uplink transmission and then resolve an overlap associated with the reception of the SSB. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a network entity to indicate one or more wake-up radio (WUR) configurations to a user equipment (UE), which may communicate a desired WUR configuration with the network entity. The UE may indicate a request for the desired WUR configuration, may multiplex the request with another signal associated with the UE, or both. Additionally, or alternatively, the network entity may indicate a single WUR configuration to the UE, which may be determined according to desired configurations, a class of WUR, or both associated with a group of UEs including the UE. Such techniques may support a reduced overall power expenditure of the UE by improving WUR operation.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) with concurrent sidelink and network link connections to operate the sidelink connection in accordance with a configured behavior associated with a bandwidth part (BWP) operation mode on the network link. The UE behavior may include, for example, no impact on sidelink activity when the network link is in a dormant or network energy saving (NES) mode, discontinuation of sidelink operation when the BWP is configured with a dormant or NES operation mode, or sidelink operation only in an identified sidelink mode when the BWP is configured with a dormant or NES operation mode. The sidelink operation mode based on NES mode of a network link BWP may be signaled to the UE on a per-BWP basis, or based on configuration and separate indication when a BWP is enabled.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: Handling of asynchronous multi-carrier is discussed. In new radio (NR) fifth generation (5G) networks, the potential for provision of multi-carrier operations (e.g., carrier aggregation (CA), dual connectivity (DC), etc.) that include asynchronous component carriers (CCs) has been proposed. However, because of the asynchronous relationship network entities, such as base stations and user equipments (UEs) will manage the asynchronous CCs by obtaining timing offset information, either through derivation or direct signaling, and determining a subframe correspondence based on the timing offset relative to a reference CC. By determining the subframe correspondence to the reference CC, the base stations and UEs can accurately map communications over the asynchronous CCs to the appropriate subframes across CCs.

The UE then transmits the uplink message in accordance with the CBG scheduling configuration, where the set of CBGs are mapped to one of the first or second codeword in accordance with the first mapping configuration, or where the set of CBGs are mapped to the first and second codewords in accordance with the second mapping configuration.

Abstract: Method and apparatus for restrictions on sidelink transmission parameters for UEs. The apparatus receives a configuration of sidelink transmission parameters based on at least one of a height of the UE, a UE service range, or an area of a UE location. The apparatus communicates based on the sidelink transmission parameters and at least one of the height of the UE, the UE service range, or the area of the UE location. The sidelink transmission parameters comprise a height based condition based on a height threshold. The sidelink transmission parameters indicate for the UE to transmit sidelink transmissions using a first restriction to transmit a transport block when the UE height is greater than or equal to the height threshold and to transmit sidelink transmissions using a second message and a second restriction to transmit the transport block when the UE height is below the height threshold.
