Abstract: Certain aspects of the present disclosure provide techniques for a random backoff procedure in a wireless communication network such as a new radio (NR) network. A method for wireless communications that can be performed by a user equipment (UE) is provided. The method includes sending a random access preamble to a base station (BS) during a random access procedure. The method includes receiving a random access response from the BS including a backoff indicator. The method includes determining whether to send a contention-free random access (CFRA) preamble to the BS during the backoff period based, at least in part, on a type of the random access procedure.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may identify a jitter pattern for a wakeup message. A station may listen using a wakeup radio for a wakeup message during wakeup listening periods according to the identified jitter pattern. A station may receive a preamble having a first bandwidth and a wakeup message having a second bandwidth. An AP may transmit an identifier key to a station, and the station may determine a rotating identifier associated with the AP based on the received identifier key. The station may receive a wakeup message from the AP, compare a sender identifier with the rotating identifier, and power on a second radio. A station may also receive a wakeup message that includes an indication of which station are to be activated.

Abstract: Aspects of the disclosure relate to communication of power headroom reports in wireless communication networks. A user equipment (UE) may measure a path loss based on a triggering path loss reference signal (PL-RS) and trigger generation of a power headroom report (PHR) based on the path loss. The UE may identify uplink resources for communication of the PHR to a base station and determine whether the uplink resources are quasi-co-located with the triggering PL-RS. When the uplink resources are quasi-co-located with the triggering PL-RS, the user equipment may transmit the PHR utilizing the uplink resources. Otherwise, the UE may generate the PHR such that it includes information identifying the triggering PL-RS.

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.
