Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.

Abstract: Methods, systems, and devices for wireless communications at a first user equipment (UE) are described. A first UE may receive one or more control signaling messages including first scheduling parameters for a common codeword associated with downlink data for the first UE and with downlink data for a second UE and one or more second scheduling parameters for a private codeword associated with additional downlink data for the first UE. The first UE may receive a physical downlink shared channel message including the common codeword mapped to one or more first layers of the physical downlink shared channel message and the private codeword mapped to one or more second layers of the physical downlink shared channel message. Additionally or alternatively, the first UE may receive a first physical downlink shared channel message including the common codeword and a second physical downlink shared channel message including the private codeword.

Abstract: Methods, systems, and devices for wireless communications are described. To communicate using non-restricted radio capabilities, a user equipment (UE) may transmit a UE capability message to a network (e.g., via a base station) that indicates a set of radio capabilities that the UE may use to communicate. The network may identify subscription information for the UE and may determine one or more restricted radio capabilities of the set of radio capabilities based on the subscription information for the UE. The network may transmit a message to the UE that includes a radio capability modification indication indicating the one or more restricted radio capabilities and a UE radio capability identifier corresponding to the subset of radio capabilities of the set of radio capabilities that are not restricted. The UE may receive the message, identify the restricted radio capabilities, and communicate with the network using the subset of non-restricted radio capabilities.

Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Abstract: Aspects for enhanced logical channel prioritization mapping procedures and restrictions are disclosed. In one aspect, a method of wireless communication includes transmitting, by a network entity, a logical channel prioritization (LCP) restriction configuration for a logical channel indicating a set of Sounding Reference Signal (SRS) configurations associated with the logical channel; determining, by the network entity, data of the logical channel of a particular UE is to be scheduled; transmitting, by the network entity, an uplink grant indicating an uplink grant instance for the particular UE, wherein the uplink grant instance indicates an SRS configuration of the set of SRS configurations; and receiving, by the network entity, a transmission corresponding to the uplink grant instance and including the data of the logical channel. Additional aspects are described.

Abstract: In some implementations, a method of wireless communication includes obtaining, at a user equipment (UE), an allocation of frequency resources for a group common demodulation reference signal (GC-DMRS) associated with a plurality of UEs that include the UE. The method also includes receiving, at the UE from a base station, a frequency domain resource allocation (FDRA) for a physical downlink shared channel (PDSCH) scheduled for transmission to the UE. The method includes receiving, from the base station, the GC-DMRS and the PDSCH. The method also includes generating a channel estimate based on the GC-DMRS and the allocation of frequency resources to the GC-DMRS. The method further includes demodulating the PDSCH based on the channel estimate. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may establish connectivity between the wireless device and a user equipment (UE) via a first communication path, and between the wireless device and the UE via a second communication path that includes a relay device. The wireless device may transmit, via the first communication path, a first message in a first format to the UE, including first data, and transmit, via the second communication path to the relay device, a second message in a second format and including the first data, the second format indicating that the relay device is to relay the first data to the UE. The relay device may receive, via a first portion of the second communication path, the first message and may transmit, to the UE via a second portion of the second path, a second message including the first data.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.
