Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.

Abstract: The disclosure relates to methods, devices, and systems for wireless communications. In some wireless communications systems, a base station may transmit a multicast message to a group of user equipment (UEs), and the UEs may provide feedback for the multicast message. In some implementations, the base station may configure the UEs to transmit feedback for multicast messages. In some example, the UEs may transmit group-negative acknowledgment (NACK) feedback information for multicast messages that are not successfully received at the UEs. In some other examples, each UE may be configured with UE-specific uplink control channel resources for transmitting hybrid automatic repeat request (HARQ) feedback for a multicast message. In some implementations, a UE may support feedback for both unicast and multicast messages. The semi-static codebook for unicast, multicast, or both may account for whether the UE is capable of concurrently receiving unicast and multicast messages in a slot.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station and at the UE of a group of UEs, control signaling indicating a link between a first search space set and a second search space set used for a multicast broadcast service, where a first downlink control channel for the group of UEs is transmitted in the first search space set and a second downlink control channel is transmitted in the second search space set, monitoring the first search space set for a first instance of control information in the first downlink control channel and the second search space set for a second instance of the control information in the second downlink control channel, and decoding the first instance or the second instance of the control information, or both, based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.

Abstract: The present disclosure relates to transmitting and receiving a group wake-up signal (WUS) in conjunction with an ungrouped WUS. A base station may group one or more UEs in a UE group, while other UEs may not be assigned to a UE group. The configuration of WUS resources and WUS sequences for grouped UEs and other UEs is a challenge. The base station may transmit, to one or more UEs in the UE group, a resource allocation of a group WUS resource within a set of WUS resources associated with a paging occasion that is assigned to the one or more UEs in the UE group. A UE, after receiving the resource allocation, may determine a location of the group WUS resource within the set of WUS resources. The UE may monitor for a group WUS at the determined location in the resource allocation of the group WUS resource.

Abstract: Methods, systems, and devices for wireless communications are described. A downlink shared channel scheduling delay and an acknowledgment feedback delay may be jointly encoded and sent to a user equipment (UE). For example, a downlink control information (DCI) field may jointly indicate the downlink shared channel scheduling delay and the acknowledgment feedback delay in a field of ‘X’ bits, where ‘X’ is configurable by a base station (e.g., via radio resource control (RRC) signaling). Subsequently, the UE may then determine the downlink shared channel scheduling delay and the acknowledgment feedback delay from the DCI by using respective equations based on a value from the jointly encoded indication or by using a table based on the value from the jointly encoded indication. Additionally, the downlink shared channel scheduling delay and the acknowledgment feedback delay may be expressed in terms of absolute subframes, invalid/valid subframes, or both.

Abstract: Methods, systems, and devices for wireless communications are described that support multiplexing multicast and unicast feedback. A base station may provision different subsets of resources from a set of resources for multicast feedback message transmission based on channel metric(s) of a user equipment (UE). The set of resources may include a plurality of subsets of resources, with each subset of resources being associated with a corresponding channel metric or range of channel metrics associated with each UE receiving the multicast transmission. A UE may determine that a feedback indication is to be provided in response to the multicast transmission, and select a subset of resources from the plurality of subsets of resources based on its own channel metric. The UE may multiplex the multicast feedback, an indication of the selected subset, and unicast feedback in a multiplexed feedback transmission to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include establishing a connection between the UE and a network node of a non-terrestrial network, identifying, based on a synchronization failure event and while the UE is in a connected mode in accordance with establishing the connection, that a location failure condition has occurred for the connection, and performing, at least in part in response to the location failure condition, one or more actions of a location failure recovery procedure to restore a synchronization associated with the connection.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may activate or release one or more semi-persistent scheduling (SPS) configurations for group-common downlink shared channels based on signaling from a base station. For example, the UE may receive downlink control information (DCI) from the base station that includes a feedback process field, where a value of the feedback process field indicates at least one of one or more SPS configurations is to be activated. In some examples, the base station may transmit the DCI in a group-common downlink control channel or in a UE-specific downlink control channel. Additionally, the base station may transmit a deactivation message to the UE to indicate for the UE to release one or more activated SPS configurations, where the deactivation message is transmitted in a group-common downlink control channel or a UE-specific downlink control channel.
