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: In an access network, a base station may aggregate data packets for a user equipment (UE) into transport blocks and configure a control channel to allow the UE to sleep between control channel monitoring occasions to save power. Such data aggregation, however, may be subject to changes in traffic load and/or link quality that may result in a too low data rate or too frequent monitoring. A base station that receives data to transmit to the UE and aggregates the data according to configured control configuration parameters of the UE may determine that a link quality or a traffic load for the UE has changed. The base station may reconfigure the control channel configuration parameters of the UE based on at least one of the link quality or the traffic load in order to obtain a data rate that satisfy the traffic load for the UE.

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: Aspects of the present disclosure relate to prioritized random access procedures in wireless systems. An exemplary method generally includes receiving, from a user equipment, a random access request including information identifying a type of a random access event being invoked, identifying one or more parameters associated with a backoff interval to be observed at the user equipment based, at least in part, on a priority associated with the type of the random access event, and transmitting, to the user equipment, a random access response including the identified one or more parameters.

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: Aspects of the present disclosure implement techniques for enhancing the LCP procedures that enables UEs to share resources more efficiently among different services and applications when the UE is configured with multiple numerologies. Particularly, each logical channel may be configured with a pair of total PBR and BSD by the network entity. For a logical channel mapped to multiple numerologies, network entity may configure a pair of prioritized bit rate (PBR) and bucket size duration (BSR) for each of its numerologies, with the constraint that the sum of the PBRs and BSDs allocated for the individual numerologies may equal its total PBR and BSR.

Abstract: A leader-follower protocol is provided for wireless communication in a BAN. A connection is established between a leader of the BAN and at least one follower in the BAN. The follower refrains from transmitting until a transmission is received from the leader. The transmission from the leader triggers a transmission opportunity at the follower for a window of time. Once the follower receives a transmission from the leader, the follower may then transmit a second transmission to the leader within the window of time. The transmission from the leader that triggers the transmission opportunity for the follower may be a data transmission, a poll transmission, an ACK a sleep mode message, etc. After transmitting a transmission to the a follower, the leader refrains from transmitting for the window of time in order to accommodate the transmission opportunity for the at least one follower.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reliable transmission of system information (SI). In some cases, a UE may send an indication to request SI in an on-demand manner. For example, a method for wireless communications by a UE may include determining system information (SI) desired by the UE is not currently being broadcast. The method for further include sending, in response to the determination, a first indication to request the SI, and sending a second indication to confirm reception of the requested SI or to indicate the UE has not received the requested SI after a time period.

Abstract: A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.

Abstract: A method of operation of an electronic device includes receiving a discovery message from an access point using a wakeup receiver of the electronic device. The method further includes activating a modem of the electronic device in response to receiving the discovery message. Operation of the wakeup receiver is associated with a first power consumption that is less than a second power consumption associated with operation of the modem. The method further includes performing an association process with the access point using the modem after activating the modem.
