Abstract: Methods and apparatus for wireless communication are described. A method may include receiving at a user equipment (UE) a number of allocated interlaces for an uplink transmission over a shared spectrum, each of which may include a plurality of non-contiguous resource blocks (RB) of the shared spectrum. In some cases, the number of allocated interlaces is unsupported by joint interlace precoding hardware of the UE and the allocated interlaces may be partitioned into subsets of interlaces which may be a size supported by the joint interlace precoding hardware. Reference signals may be generated for the RBs of the allocated interlaces according to a reference signal sequence based on an ordering of the RBs for the allocated interlaces within the shared spectrum.

Abstract: Uplink control channel management is disclosed for LTE/LTE-A communication systems with unlicensed spectrum in which two or more physical resource blocks (PRBs) are allocated for uplink control channel transmission. The uplink control information (UCI) payload may be determined based on clear channel assessment (CCA) information associated with carriers scheduled for transmission of the UCI data. With the UCI payload determined, two or more uplink control channel messages may be generated according to at least one control channel format, wherein uplink control channel messages include the UCI payload. These generated uplink control channel messages may then be transmitted over the allocated PRBs.

Abstract: Methods, systems, and devices for wireless communications are described. To support communications across a wideband, a base station and user equipment (UE) may communicate across the wideband using a set of sub-bands that span the carrier bandwidth (e.g., the wideband). In some cases, the UE may transmit, to the base station, an indication of a capability of the UE to communicate a wideband communication with the base station via the set of sub-band based communications with the base station. The UE may receive, from the base station (and, in some cases based on the capability of the UE), a configuration for communicating with the base station in the carrier bandwidth using the set of sub-bands. Then, the UE may communicate with the base station in the carrier bandwidth using one or more of the set of sub-bands in accordance with the configuration.

Abstract: Aspects presented herein may enable a network entity to configure a group of UEs to simultaneously transmit reference signals and to simultaneously transmit gradient vectors to the network entity, such that the network entity may receive the gradient vectors from the group of UEs as an aggregated gradient vector over the air. In one aspect, a base transmits, to a group of UEs, a configuration that configures the group of UEs to simultaneously transmit one or more group-common reference signals and to simultaneously transmit one or more gradient vectors associated with a federated learning procedure. The network entity receives, from the group of UEs, the one or more group-common reference signals and the one or more gradient vectors based on the configuration via multiple channels. The network entity calculates an average gradient vector based on the one or more group-common reference signals and the one or more gradient vectors.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

Abstract: In an aspect, a UE receives first positioning assistance data (AD). The UE transmits an indication to a network component (e.g., BS, core network component, LMF, etc.) that the UE has received the first positioning AD. The network component determines second positioning AD that is based at least in part upon the first positioning AD. The network component transmits the second positioning AD to the UE.

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, a first radio resource control (RRC) configuration message that is associated with a first subband and that indicates a first set of transmission configuration indicator (TCI) states for use on the first subband. The UE may further receive, from the base station, a second RRC configuration message that is associated with a second subband included in the wideband channel and that indicates a second set of TCI states for use on the second subband. As an alternative, the UE may receive, from the base station, an RRC configuration message that includes at least a first list of first TCI states associated with a first subband and a second list of second TCI states associated with a second subband. Numerous other aspects are described.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may determine an energy detection threshold of a reference bandwidth, the energy detection threshold being based on at least one of a transmit power or a power class. The apparatus may also measure an interference level of at least one signal. Additionally, the apparatus may adjust the energy detection threshold of the reference bandwidth based on a sensing bandwidth. The apparatus may also determine whether a transmission medium is available based on at least one of the adjusted energy detection threshold or the measured interference level of the at least one signal.
