Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of master information blocks (MIBs) on a narrowband physical broadcast channel (NPBCH). The UE may determine an NPBCH signal power based at least in part on the plurality of MIBs. The UE may estimate a narrowband reference signal received power (NRSRP) parameter based at least in part on the NPBCH signal power. In some aspects, a base station may determine whether to enable or disable NPBCH-based estimates of an NRSRP parameter for a UE. The base station may transmit, to the UE, an indication of whether NPBCH-based estimates of the NRSRP parameter are enabled or disabled for the UE based at least in part on the determination. Numerous other aspects are provided.

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 wake-up signal periodicity and perform discontinuous monitoring for a plurality of wake-up signals based at least in part on the wake-up signal periodicity. In some cases, the UE may perform a radio resource management (RRM) measurement according to an RRM measurement periodicity that corresponds to the wake-up signal periodicity. In such cases, the UE may monitor for paging messages to receive paging information, or updates to system information, during one or more wake-up signal occasions that correspond to the RRM measurement periodicity. For instance, paging information may be received while the UE is performing RRM measurements, where paging message may be monitored for based on the wake-up signal periodicity.

Abstract: Methods, apparatuses, and computer-readable medium for SRS are provided. An example UE may receive an SRS configuration and a downlink transmission scheduling an uplink transmission, the uplink transmission being scheduled on a CC, the SRS configuration comprising one or more additional SRS symbols relative to a first set of SRS symbols associated with an aperiodic trigger Type 1 or a periodic trigger Type 0, the one or more additional SRS symbols being scheduled on a destination CC at least one of the one or more additional SRS symbols overlapping at least partially with the uplink transmission. The example UE may drop or delay transmission of at least a part of an SRS in the one or more additional SRS symbols on the destination CC or at least a part of the uplink transmission on the source CC.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: A low complexity user equipment (UE) may be in communication with another UE (e.g., with a premium UE or more capable UE) via a device-to-device communication link (e.g., via sidelink), and the low complexity UE may leverage the device-to-device link to improve (e.g., simplify, expedite, etc.) random access procedures performed by the low complexity UE. For example, a low complexity UE may request contention free random access (CFRA) resources via the device-to-device link with another UE. Another device (e.g., another UE in device-to-device communication with the low complexity UE) may receive the request from the low complexity UE and forward the request to the network (e.g., to a base station). The network may then configure CFRA resources for the low complexity UE. Upon receiving the CFRA configuration, the low complexity UE may perform a random access procedure (e.g., a CFRA procedure) with the network (e.g., with the base station) accordingly.

Abstract: Aspects include systems, methods, devices, and non-transitory processor readable storage mediums for managing a broadcast signal of an apparatus for wireless communication. Various aspects may enable an apparatus to send a message using either omnidirectional transmissions or beamformed transmission based on whether the altitude of the apparatus meets an altitude threshold. In some implementations and aspects, the processor of the apparatus may determine a type of the message and may select the altitude threshold based on the determined message type. In some implementations and aspects, the processor of the apparatus may send the message using beamformed transmissions in response to determining that the message is intended for reception by a certain type of second apparatus.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may apply a scaling factor to a transport block of a first size, where the scaling factor may increase the transport block from the first size to a second size. The base station may interleave a set of parts of the transport block of the second size across a set of transmission time intervals (TTIs) in accordance with a transport block allocation pattern, where the set of TTIs may be contiguous or separated from each other by one or more intervening intervals. The base station may transmit, to a user equipment, an indication of the transport block allocation pattern applied to the transport block of the second size, and may transmit the set of parts of the transport block of the second size across the set of TTIs in accordance with the transport block allocation pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method generally includes receiving a configuration message for narrowband internet of things (NB-IoT) communication, the configuration message indicating one or more parameters for uplink transmission using a modulation and coding scheme (MCS) associated with a modulation order of at least four, generating the uplink transmission, and sending the uplink transmission in accordance with the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of resources for one or more synchronization signal blocks (SSBs) associated with one or more pseudo-random sequences. The one or more pseudo-random sequences and the set of resources may be indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier, and a key. In some examples, the UE may monitor a set of resources within a control resource set for a downlink control channel, where the set of resources for the downlink control channel is based on an output of the PRF. The UE communicate with a network entity via a cell associated with the cell identifier based on the monitoring.
