Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving signaling from a base station to activate a semi-persistent scheduling (SPS) configuration for transmission between the base station and the UE, and receiving a hybrid automatic repeat request (HARQ) timing for downlink transmissions based at least in part on the SPS configuration being activated. In another example, the method includes establishing a connection with a base station using a component carrier (CC), the CC having a plurality of bandwidth parts (BWPs), receiving signaling that indicates an SPS configuration or other types of pre-configured resources associated with at least a first BWP of the plurality of BWPs and transmitting or receiving using at least the first BWP according to the SPS configuration or other types of pre-configured resources associated with at least the first BWP.

Abstract: Processes, systems, and devices for wireless communications are described. A communication device may monitor a wakeup signal monitoring occasion in an inactive duration of a discontinuous reception (DRX) cycle. The communication device may transmit, in a first active duration of the DRX cycle, a channel state information (CSI) report on one or more resources based on monitoring the wakeup signal monitoring occasion. In some examples, the communication device may transmit an indication that the communication device requests reporting of the CSI report in the first active duration of the DRX cycle. The communication device may, in some examples, receive, in a second active duration of the DRX cycle, control information for the UE based on the CSI report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify, when using carrier aggregation and a plurality of component carrier groups, first traffic associated with a first service type and second traffic associated with a second service type for concurrent transmission. The user equipment may transmit, concurrently, the first traffic associated with the first service type using a first component carrier group of the plurality of component carrier groups, and the second traffic associated with the second service type using a second component carrier group of the plurality of component carrier groups. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may refrain from transmitting channel state information (CSI) if the CSI is configured to be transmitted during an inactive discontinuous reception (DRX) duration. The UE may determine that the CSI is configured to be transmitted during the inactive DRX duration based on determining that some or all of the configured time slot for transmitting the CSI occurs while the UE is operating in the inactive DRX duration. The UE may transmit feedback information, such as an acknowledgement (ACK), whether or not the UE drops the CSI.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, and a base station may receive, on a grant-free resource, in an ultra-reliable low-latency communications (URLLC) network, a layer 1 (L1) signal for identification of the user equipment. In some aspects, the base station may transmit, and the user equipment may monitor for and receive a reception indication as a response to the L1 signal in a reception period occurring after transmission of the L1 signal. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A periodic reception mode may be activated for a user equipment (UE), such as by receiving an activation signal. The UE may be configured with or otherwise determine a periodic schedule associated with the periodic reception mode. The base station may combine multiple packets of data and may transmit the combined data packet in accordance with the periodic schedule. The UE may identify a duration for an active state and a duration for an idle state based on the periodic schedule. The UE may monitor a control channel in accordance with a duration for the active state associated with the periodic reception mode and may sleep in accordance with a duration for the idle state associated with the periodic reception mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a device, such as a user equipment (UE), may report power headroom measurements. To support accurate and reliable power headroom reports (PHRs), the UE may receive a first downlink control information (DCI) transmission for a first cell and determine whether a second DCI transmission for a second cell is received. The UE may generate the PHR based on whether a second DCI transmission was received after the first DCI transmission and may transmit the PHR including power headroom values for both cells. The UE may determine whether to perform an actual or virtual power headroom calculation for the second cell based on when the second DCI was received. Additionally or alternatively, the UE may determine whether to drop resources scheduled by the first or second DCI and may transmit the PHR in the remaining resources.

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.
