    Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A wireless device, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio and configured to cause the wireless device to: determine a gap period is to be applied between a first uplink transmission to a cellular base station via a first transmission reception point (TRP) and a second uplink transmission to the cellular base station via a second TRP; and perform the first and second uplink transmissions consecutively with the gap period applied between them.

    Abstract: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.

    Abstract: A user equipment (UE) may perform configured to perform layer 1 (L1) measurements and layer 3 (L3) measurements. The UE receives a first configuration for layer 1 (L1) measurements of a resource set comprising a plurality of reference signals (RS) and a second configuration for layer 3 (L3) measurements, the first configuration including periodic measurement occasions and a reporting periodicity for transmitting measurement reports comprising the L1 measurements, determines the L3 measurements collide with at least one of the plurality of RSs for the L1 measurements, wherein the colliding causes a determination of the L1 measurements to be muted for the at least one RS during at least one of the measurement occasions and alters at least a first measurement report so that the L1 measurements that collide with the L3 measurements are not reported in at least one reporting periodicity.

    Abstract: A user equipment (UE) receives TCI state configurations for a plurality of signals, wherein a first state configuration comprises a first port for a first signal being quasi-co-located (QCL) to a second port of a second signal and a second state configuration comprises the second port of the second signal being QCL to a third port of a third signal and determines a TCI chain comprising the first, second and third signals so that channel measurements for each one of the first, second and third signals are applied to channel measurements for each other one of the first, second and third signals, wherein at least one of the first, second or third signals is an uplink (UL) signal.

    Abstract: A user equipment (UE) is configured to monitor synchronization signal blocks (SSB) transmitted by a base station of a network. The UE receives a configuration comprising a first indication of a quasi-co-location (QCL) relationship between synchronization signal block (SSB) positions and a second indication of a location of one or more sets of target SSBs, wherein SSBs in each of one or more sets of target SSBs are quasi-co-located, determines a number of SSB occasions corresponding to each set of the one or more sets of target SSBs to be transmitted by the base station and determines a monitoring scheme for the one or more sets of target SSBs based on, at least, the configuration and the number of SSB occasions corresponding to each set of target SSBs.
