Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for signaling cross-division duplex configurations. One of the methods includes identifying, by a first device and for a first link with a second device, a switch in a first bandwidth part to a second bandwidth part for the first link, the first link associated with a second link having a third bandwidth part; determining, by the first device, whether a bandwidth band between the second bandwidth part and the third bandwidth part satisfies a threshold guard band; and selectively determining to maintain the third bandwidth part for the second link or to switch the third bandwidth part to a fourth bandwidth part for the second link using a result of the determination whether the bandwidth band between the second bandwidth part and the third bandwidth part satisfies the threshold guard band.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A user equipment (UE) may receive, from a base station, information indicating that a coverage enhancement mode is supported. The UE may determine whether to enter the coverage enhancement mode based on a downlink signal synchronization block (DL SSB). In response to determining to enter the coverage enhancement mode, the UE may transmit a reserved preamble to the base station to initiate random access for the coverage enhancement mode.

Abstract: Systems and methods provide user equipment (UE) coordinated channel state information (CSI) measurement and reporting. One or both of a first UE and a second UE may perform CSI measurement, but only the first UE sends a CSI report to a base station.

Abstract: This disclosure relates to techniques for configuring physical uplink shared channel transmissions with improved reliability in a wireless communication system. A cellular base station may establish a wireless link with a wireless device. The cellular base station may provide uplink data transmission configuration information to the wireless device. The uplink data transmission configuration information may configure an uplink data transmission to multiple transmission-reception-points. The cellular base station may receive at least a portion of the uplink data transmission.

Abstract: An approach for wireless communications to support reduced capability New Radio (NR) with larger available control resource sets (CORESET) bandwidths. Examples include a frequency-hopping CORESET with a predefined hopping pattern configured by higher layers, such as RRC signaling or MAC Control Element (CE) on a per CORESET per UE or purely per UE basis. Frequency hopping patterns for CORESET transmissions include the use of PRBs for CORESETs that are mirrored with respect to the central frequency of active bandwidth part (BWP), and the use of a random parameter to step through the frequency pattern. The sub-band location of the physical downlink shared channel that is scheduled by the physical downlink control channel may be indicated using the DCI format, or may be based on a last slot for PDCCH transmission.

Abstract: A user equipment (UE) reports radio access capabilities to a network. The UE receives a request from a network for radio access capabilities of the UE, determining one or more radio access capabilities related to physical downlink control channel (PDCCH) blind decoding by the UE, generates a message that includes the one or more radio access capabilities of the UE and transmits the message to the network.
