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. A user equipment (UE) may transmit a UE capability message to a base station, the UE capability message including an indication of a UE type, the UE type associated with at least one of a reduced bandwidth, or a reduced number of antennas, or a combination thereof, for the UE. The UE may monitor, based at least in part on a control resource set that is based at least in part on the UE type, a control channel for a downlink grant for downlink resources. The UE may receive, based at least in part on the monitoring, a grant identifying the downlink resources for communicating with the base station. The UE may communicate with the base station using the identified downlink resources.

Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

Abstract: Methods, systems, and devices for wireless communications are described. Transport blocks may be scheduled using a single downlink control information (DCI) message. A wireless device may identify mapping pattern for mapping the transport blocks and repetitions of the transport blocks to communication resources. Mapping the transport blocks, or determining a mapping of the transport blocks, to communication resources may include partitioning the communication resources into subunits, where each subunit includes resources spread across each subband of a frequency hopping pattern and at least one instance of each of the scheduled transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. that support preconfigured uplink resources (PUR) in wireless communications. A base station may communicate that support for PUR is available, and may allocate PUR resources to a user equipment (UE) based on requests from the UE. The UE may receive an indication that the base station supports PUR, such as via a system information block (SIB), determine to request PUR, and transmit a PUR request message to the base station. A PUR response from the base station may indicate a PUR allocation for the UE that may be used for uplink transmissions. Uplink transmissions that use PUR may be acknowledged by the base station based on a QOS associated with the uplink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a wakeup signal (WUS) from a network node, such as a base station, before listening for a paging message. The UE may assume a maximum duration (Wmax) for the WUS based on a dependency on variables associated with the base station and WUS. In some cases, the UE may determine not to monitor a WUS for the Wmax and may engage in an early termination based on the determination. That is, the UE may monitor the WUS for a time shorter than Wmax. The UE may assume the shorter time has a dependency on variables associated with the base station and WUS. The base station may indicate this dependency to the UE either implicitly or explicitly.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a configuration of a page monitoring periodicity, and a configuration of a wake-up signal from a network node, such as a base station. The UE may perform discontinuous monitoring for a plurality of wake-up signals based at least in part on a wake-up signal periodicity, and receive the wake-up signal on the wake-up signal periodicity. The UE may then monitor for paging messages to receive paging information, or updates to system information, during a page monitoring period according to the page monitoring periodicity, the wake-up signal periodicity, the received wake-up signal, or a combination thereof.
