Abstract: Methods, systems, and devices for wireless communications are described in which one or more semi-persistent scheduling (SPS) configurations may provide periodic resources for communications between a base station and a user equipment (UE). One or more of the SPS configurations may also provide alternative resources that may be used for the communications in the event that a communication on the periodic or dynamically scheduled resources is cancelled. In the event that the base station transmits a cancellation indicator that cancels one or more of the communications, it may be determined whether to use the alternative resources for the associated communication. The determination to sue the alternative resources may be based on a time duration of the cancellation, a frequency portion of the cancelled resources, or combinations thereof.

Abstract: Certain aspects of the present disclosure provide techniques for providing direct current locations of bandwidth parts (BWPs) in a BWP hopping pattern. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the UE may receive, from a base station (BS), a request for uplink direct current location information of the UE, wherein the UE is configured to transmit to the BS on an uplink according to a frequency hopping pattern for hopping between a plurality of uplink bandwidth parts corresponding to different frequency bandwidths. In some examples, the UE may transmit, to the BS, at least one uplink direct current location applicable to the plurality of uplink bandwidth parts. In some examples, the UE may transmit, to the BS, on the uplink according to the frequency hopping pattern.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to determine whether to request coverage enhancement for a random access procedure based on a condition of a channel between the UE and a base station failing to satisfy a threshold. The UE may transmit a request for coverage enhancement for a second random access message (e.g., a random access Message 4 (Msg4)) using a first random access message (e.g., a random access Message 3 (Msg3)). The base station may determine whether to perform the coverage enhancement in response to receiving the first random access message and may transmit the second random access message accordingly. Implementing aspects of the present disclosure may enable coverage enhancement for random access procedures in wireless communications systems.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration of a set of synchronization signal blocks (SSBs) to be transmitted by a first base station or a second base station. In some cases, the UE may be served by the first base station and the UE may receive, from the first base station or the second base station, a message indicating that a transmission of at least one SSB of the set of SSBs is canceled and indicating resources for a signal (e.g., a reference signal, alternative SSB transmission) to be transmitted by the first base station or the second base station as an alternative to the canceled at least one SSB. The UE may receive, based on the received message from the first base station or the second base station, the signal using the indicated resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive at least one control message including an indication that frequency hopping for downlink control information (DCI) is activated for physical downlink shared channel (PDSCH). The UE may determine a frequency hopping configuration (e.g., a frequency hopping pattern) for the DCI, which may be applied for PDSCH occasions, for a group of PDSCH occasions, or until changed by another indication from the network. The UE may also receive a downlink reference according to the frequency hopping configuration. For example, if intra-occasion frequency hopping is activated, demodulation reference signals (DMRS) may be received in each hop of the DCI within a PDSCH occasion, and if inter-occasion frequency hopping is activated, DMRS may be received once per PDSCH occasion.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: Methods, systems, and devices for wireless communications are described to support transmission of a resource modification information request from a user equipment (UE) to a base station, where the resource modification request may request an increased density of uplink transmission occasions. For example, the resource modification request may request an increase from a first density of uplink transmission occasions configured for the UE. The resource modification request may include a request for a decreased periodicity of uplink transmission occasions, an increased number of groups of repetitions for uplink transmission occasions, an increased number of resource blocks for uplink transmission occasions, or an increased modulation coding scheme for uplink transmission occasions. The base station may receive the resource modification request and may transmit a message to the UE, which may indicate a modified or new uplink grant configuration for uplink transmission occasions having a higher density (e.g., a second density).

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit a number of channel state information (CSI) reports for a CSI reporting procedure as part of a beam management procedure. The UE may transmit a first number of CSI reports of the CSI reporting procedure to the base station using a first set of transmission parameters associated with a first reliability level. The base station may transmit a control message to the UE indicating a second set of transmission parameters associated with a second reliability level and the UE may transmit a second number of CSI reports of the CSI reporting procedure to the base station using the second set of transmission parameters.

Abstract: Aspects of the disclosure relate to techniques for paging operations in a wireless communication network that uses frequency hopping between bandwidth parts (BWPs). A paging indicator message, carried in a paging indicator search space of a given BWP, indicates to a mobile device monitoring the paging indicator search space that a paging message may arrive at the device's next paging occasion. A mobile device using frequency hopping may locate, and hop to, an anchor BWP with a paging indicator search space according to a paging indication periodicity. When it receives a paging indicator message, the device may locate, and hop to, a paging BWP and monitor a paging search space for a paging message. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described to support using one of multiple types of synchronization signal blocks (SSBs) to perform one or more management procedures. A base station may configure and transmit one or more SSBs of second type that are smaller than SSBs of a first type. For instance, SSBs of a second type may include a first subset of signals and may exclude a second subset of the signals that are included in an SSB of the first type. An SSB of the second type may be transmitted in an active bandwidth region used for communications between a user equipment (UE) and the base station. The UE may receive an SSB of the second type in an active bandwidth region, may perform one or more measurements using the SSB of the second type, and may perform one or more management procedures.
