Abstract: Methods, systems, and devices for wireless communication are described. One method may include receiving, at user equipment (UE), a control resource set configuration message from a base station; identifying an overlap between a first control resource set and a second control resource set of a wireless channel; identifying a priority level of the first control resource set and a priority level of the second control resource set based on the control resource set configuration message; and monitoring the first control resource set based on the identified overlap, the priority level of the first control resource set, and the priority level of the second control resource set.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently monitoring for wake-up signaling from one or more transmission and reception points (TRPs), the wake-up signaling indicating the presence of data or control information in an on-duration state of a discontinuous reception (DRX) cycle. In particular, select TRPs may be used to transmit wake-up signaling to a user equipment (UE), and the UE may be configured to monitor for wake-up signaling from the select TRPs. Once the UE receives wake-up signaling prior to an on-duration state of a DRX cycle from any of the select TRPs, the UE may then determine the TRPs scheduled to transmit data or control information in the on-duration state (e.g., based on the WUS or based on further control signaling), and the UE may receive the data or control information from the TRPs in the on-duration state.

Abstract: Physical random access channel (PRACH) configuration on new radio unlicensed (NR-U) networks is disclosed. A UE may perform PRACH transmission either with a transmission opportunity (TXOP) or outside of a TXOP. The UE monitors for a control signal, such as a preamble or common control signal, identifying a TXOP. The UE may obtain an autonomous random access configuration for communications outside of the current TXOP that identifies a random access slot includes a plurality of random access occasions. If the UE fails to detect the control signal, it transmits an autonomous random access signal in a random access occasion corresponding to a beam direction of its location in relation to the base station. Otherwise, upon detection of the control signal and receipt of a trigger signal, the UE may transmit a random access request within the TXOP.

Abstract: Random access channel access and validity procedures are disclosed. In one aspect, the medium access control (MAC) indications multiple random access occasions (ROs) to user equipments (UEs) for random access transmissions. In such aspect, random access failure would only be declared if listen before talk (LBT) procedures for the random access transmission fail on all of the ROs indicated by the MAC layer. Similarly, in additional aspects, a UE will not apply a backoff value for any LBT failures for random access attempts that occur within an LBT time window. In further aspects, a UE may determine the validity of ROs that overlap with a discovery reference signal measurement timing configuration (DMTC) window. In such aspects, the UE may not use overlapping ROs or may determine a portion of the DMTC window that is not used for base station transmissions and declare the overlapping ROs with the unused portion valid.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for encoding uplink data for transmission based on control information included in a first uplink grant corresponding to a first set of uplink resources, receiving a second uplink grant associated with a second set of uplink resources, wherein the second uplink grant is associated with the encoded uplink data for transmission, determining a starting time (e.g., a first delay or a second delay) for the second set of uplink resources based at least in part on a timing of the encoding with respect to the second uplink grant, and transmitting uplink data during the second set of uplink resources based on the determined starting time.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network may schedule a user equipment (UE) for multiple transmission/reception point (TRP) communication. The network may transmit a single downlink control information (DCI) message to the UE to dynamically configure multiple transmission configuration indicator (TCI) states for the multiple TRPs. In a first example, the DCI message may include a bit field indicating a set of antenna ports and the multi-TRP scheme for transmission. In a second example, the DCI message may include a separate field indicating the multi-TRP scheme (e.g., based on UE capabilities). In a third example, the DCI may indicate redundancy versions (RVs) for different TRPs in an RV field or across multiple fields. In a fourth example, the DCI may include an indication of a precoding resource block group (PRG) size that may be interpreted differently based on the indicated multi-TRP scheme.

Abstract: Wireless communications systems and methods related to multiplexing uplink control channel signals from different users are provided. A first wireless communication device obtains an uplink control channel multiplex configuration indicating a first frequency spreading sequence and at least one of a second frequency spreading sequence or a first spatial direction. The first wireless communication device communicates, with a second wireless communication device, a first uplink control channel signal including a first reference signal and a first uplink control information signal in a frequency spectrum based on the uplink control channel multiplex configuration. The first reference signal is based on the first frequency spreading sequence and the first uplink control information signal is based on at least one of the second frequency spreading sequence or the first spatial direction.

Abstract: A method, apparatus, and computer-readable medium that enable and disable autonomous downlink transmission (ADT) capability at a user equipment (UE) or a gNB are disclosed. The ADT capability is enabled when a triggering event occurs. The ADT capability is realized in part via initiating a listen before talk (LBT) procedure of a first LBT type to obtain an uplink (UL) transmission opportunity (TxOP) after determining that the UE does not have any UL data to transmit, transmitting uplink control information (UCI) with a limited amount of data to request for a resource grant of the TxOP for pending DL data; and receiving the pending DL data, wherein resources for receiving the pending DL data is dynamically configured via the UCI or semi-statically configured through a radio resource control (RRC) protocol message.
