Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes receiving, by the UE, a first transmission on a beam over a radio frequency spectrum during a first time interval. The first transmission includes an indication of a subsequent physical downlink control channel (PDCCH) transmission on the beam. The indication includes information about a PDCCH in a second time interval subsequent to the first time interval. The method also includes configuring a power saving state of the UE based at least in part on the indication. A method for wireless communication at a network access device includes transmitting the first transmission to at least one UE, and transmitting the PDCCH during the second time interval.

Abstract: Methods, systems, and devices for wireless communication are described. Various autonomous uplink control channel configurations may be used for unscheduled uplink transmissions. For example, a user equipment (UE) may initiate an unscheduled uplink transmission and may identify an autonomous uplink control channel configuration for the uplink transmission. The UE may transmit control information and data during an initial transmission time interval of a transmission opportunity according to the control channel configuration, where the control channel configuration control may include a number of different waveforms and payload configurations. For example, an autonomous uplink control channel configuration may include control information frequency division multiplexed or time division multiplexed with data and transmitted in one or more frequency interlaces. In some cases, the control channel configuration may include a symbol period for a clear-to-send signal, and one or more symbol periods used a guard period before the data transmission.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.

Abstract: Aspects described herein generally relate to communicating between a user equipment (UE) and a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell. An indicator can be transmitted from the cell and received by the UE to implement time division duplexing (TDD) on the uplink frequency band. Based at least in part on the indicator, communicating between the UE and the cell can include separating the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive configuration information identifying the UE as a relay node and indicating for the UE to schedule resources for other UEs. The UE may receive a single message from a network entity with the configuration information or multiple messages from the network entity with the configuration information. A remote UE may request scheduling information from the relay UE. A network entity, such as a base station, may provide one or more resources (e.g., time resources, frequency resources, or both) for the relay UE to schedule one or more remote UEs. The relay UE may send scheduling information to the one or more remote UEs based on receiving the resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a duration of a dormancy timer for switching from an active bandwidth part to a dormant bandwidth part configured for the UE; start or restart the dormancy timer based at least in part on a determination that a condition is satisfied; and switch to the dormant bandwidth part based at least in part on a determination that the dormancy timer has expired. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control signaling indicating a configuration for establishing a dual connectivity connection. The dual connectivity connection may include a wireless local area network (WLAN) link and a cellular network link. The UE may establish the WLAN link or the cellular network link as a primary link of the dual connectivity connection. The primary link may be reconfigurable between the WLAN link and the cellular network link. The dual connectivity connection may support a single radio resource control connection associated with the primary link between the UE and the network entity. The UE may communicate with the network entity using at least the primary link of the dual connectivity connection. The UE may support a single radio resource control state of the plurality of radio resource control states at a time.
