Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a mode for mapping multicast broadcast quality of service (MB-QoS) flows to logical channel identifiers and group radio network temporary identifiers (G-RNTIs); identify an MB-QoS flow from a medium access control (MAC) transport block (TB) based at least in part on the indicated mode; and decode data included in the MB-QoS flow. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support techniques for wireless communications using preconfigured uplink resources. Generally, the described techniques provide for enhancement of communication features including frequency hopping, an uplink control channel, coverage enhancement, timing advance, uplink power control, reconfiguration, a downlink control channel, a downlink data channel, retransmissions, or subcarrier spacing for a UE in idle mode. The UE may receive an uplink resource configuration for uplink communications in idle mode, the uplink resource configuration comprising an indicator associated with allocated resources for the uplink communications in idle mode and a set of parameters. The UE may transmit, while in idle mode, a first uplink transmission associated with a transport block on the allocated resources and according to one or more of the parameters, and monitor for a response to the first uplink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement transmission repetitions for transport blocks (TBs) to improve reception reliability. However, to support low latency, TBs may be transmitted in any transmission time interval (TTI) within a subframe. The systems may implement process to handle these TB repetitions. In some cases, a device may receive, during a TTI of a subframe, control information including an indication of transmission repetitions of a TB for a plurality of TTIs, identify a quantity of transmission repetitions of the TB based on the control information, and monitor for the transmission repetitions of the TB.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain, via broadcast signaling or UE-specific signaling, an indication of an uplink communications configuration for one or more uplink wireless communications that span a set of one or more transmission time intervals (TTIs). The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a network node, a paging message indicating information for communication between the network node and the UE. In some examples, the UE may receive, from a network node, a downlink alert message indicating a paging message for subsequent transmission to the UE. The UE may identify a delay based on receiving the paging message or the downlink alert message, a measurement of a communication link satisfying a threshold, or any combination thereof. The UE may establish an uplink connection with the network node based at least in part on an expiration of the delay. The UE may communicate the information using the uplink connection.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

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: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Techniques and apparatuses described herein provide for an indication that a unified access control (UAC) parameter of a user equipment (UE) has changed. For example, a paging message or direct indication information may be provided to a UE indicating that a UAC parameter has changed. In such a case, the UE may not be expected to periodically check a scheduling information list of a system information block type 1 (SIB1). Thus, battery power of UEs may be conserved and signaling resources that would otherwise be used to periodically check the scheduling information list may be conserved.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may transmit, to a base station of a non-terrestrial network, a random access request message associated with a random access procedure using a transport block size (TBS) and a power control specified for the random access request message (e.g., a payload of the random access request message) for the random access procedure. The random access request message including a random access preamble and a random access payload carrying a buffer status report (BSR) or uplink data, or both. The UE may then monitor a response window based at least in part on transmitting the random access request message. The UE may receive, from the base station of the non-terrestrial network, a response message of the random access procedure during the response window.
