Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive a first downlink control message indicating a set of parameters for a scheduling request for the UE. The UE may then receive on a receive beam a second downlink control message, which may be a layer 1 signal, and determine uplink resources for the scheduling request and a transmission configuration indicator state for the scheduling request. The UE may transmit, to the base station, the scheduling request using the uplink resources.

Abstract: This disclosure provides systems, methods, and apparatuses for jointly activating or releasing a plurality of semi-persistent scheduling (SPS) configurations using a single downlink control information (DCI) message. In some implementations, a user equipment (UE) receiving the DCI message can determine, for each SPS configuration, a number of time slots between an end of the received DCI message and a beginning of one or more downlink (DL) data frames based on a first value contained in the DCI message. The UE can also determine, for each SPS configuration, a number of time slots between an end of the DL data frames and an instance in time at which the UE is to transmit a hybrid automatic repeat request acknowledgement (HARQ-ACK) based on a second value contained in the DCI message. In some instances, the single DCI message can also jointly activate or release a plurality of configured grant (CG) configurations.

Abstract: Sub-resource pools for transmission of new radio (NR) sidelink (NR SL) over unlicensed bands is disclosed. A user equipment (UE) capable for sidelink communications may receive a sidelink configuration message from a serving base station that includes identification of a plurality of channel access types associated with a plurality of sub-resource pools for autonomous sidelink access of a shared communication channel. The UE may obtain information for a sidelink transmission over a transmission resource pool allocated for the autonomous sidelink access and determine the plurality of sub-resource pools from available resources within the transmission resource pool according to a channel access type of each resource, wherein each sub-resource pool includes a subset of resources associated with a corresponding channel access type. The UE may then select a sub-resource pool for sidelink transmission and transmit the information on a transmission resource selected from the sub-resource pool.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first downlink control information (DCI) communication for scheduling a first physical downlink shared channel (PDSCH). The first PDSCH may be associated with at least a first transmit receive point (TRP). The UE may receive a second DCI communication for scheduling a second PDSCH. The second PDSCH may be associated with a second TRP and at least one of the first TRP or a third TRP. The UE may receive downlink communications based at least in part on the first DCI communication and the second DCI communication. Numerous other aspects are provided.

Abstract: Design of robust radio link monitoring framework for unlicensed spectrum is disclosed. The network may configured two different types of radio link monitoring (RLM) reference signal (RS) resources: default resources, which are transmitted throughout a connection, and additional resources, which may be transmitted only when there has been failure of transmission or reception of the default resources. Various criteria may be used by the network to trigger scheduling transmission of the additional RLM-RS. Moreover, different criteria may prompt a user equipment (UE) to begin monitoring the additional RLM-RS resources, including autonomous and network-initiated criteria.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine that a triggering event associated with a user equipment (UE) has occurred. The UE may receive, based at least in part on an occurrence of a triggering event associated with the UE, a trigger signal that identifies resources to be used for transmission of an aperiodic tracking reference signal (TRS). The UE may receive the aperiodic TRS based at least in part on the trigger signal and the identified resources. The UE may perform at least one of a tracking function, or a synchronization function, or an alignment function, or a combination thereof, in response to the occurrence of the triggering event and based at least in part on the aperiodic TRS.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive, in an active duration of a multicast discontinuous reception (DRX) cycle, downlink control information indicating resources of a downlink data channel for a multicast message for a plurality of UE. The UE may monitor the indicated resources for the multicast message, as well as transmit, based on the monitoring the indicated resources, a feedback message corresponding to the multicast message. The UE may initiate a multicast feedback timer based on the monitoring the indicated resources for the multicast message, the multicast feedback timer indicating a time for monitoring for a retransmission of the multicast message. The multicast feedback timer may be different than a unicast feedback timer associated with unicast messages for the UE. In some examples, the UE may initiate a multicast retransmission timer following the multicast feedback timer. The multicast retransmission timer may be different than a unicast retransmission timer associated with the unicast messages.

Abstract: This disclosure provides systems, methods, and apparatuses for random access channel (RACH) occasions that overlap each other in time and frequency. In one aspect, the RACH occasions may use different preamble sequence sets. A base station may signal configuration information indicating the preamble sequence sets for the RACH occasions and information indicating a time-frequency resource allocation of the RACH occasions. A UE may perform a random access procedure in accordance with the configuration information.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication system may utilize a listen before talk (LBT) procedure prior to transmission. A base station may perform an enhanced clear channel assessment (eCCA) on one channel and a single clear channel assessment (CCA) on another channel. The base station may then send a grant for a user equipment (UE) to transmit on both channels. The UE may receive the grant, and perform a single CCA on the first channel and an eCCA on the second channel. The UE may then transmit uplink information on both the first channel and the second channel. That is, the base station may send an opportunistic grant for transmitting on the second channel even though it may not have passed eCCA at the base station. The UE may then use the channel if it passes an eCCA.
