Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for performing L1-RSRP (Layer 1 Reference Signal Received Power) measurements and/or L1-SINR (Layer 1 Signal-to-Noise and Interference Ratio) measurements on a neighbor cell. For example, some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver configured to communicate with a serving cell and a neighbor cell and a processor communicatively coupled to the transceiver. The processor determines a measurement period for a Layer 1 (L1) measurement on the neighbor cell and receives, using the transceiver, a resource from the neighbor cell during the measurement period. The processor further performs the L1 measurement on the neighbor cell using the received resource from the neighbor cell.

Abstract: Some embodiments include an apparatus, method, and computer program product for simultaneous multiple secondary cell (SCell) fast activation in a wireless communications system. Some embodiments include a user equipment (UE) that can simultaneously activate multiple SCells. In some embodiments, after receiving an activation command, the UE can receive two or more temporary reference signals (T-RSs) which are user equipment (UE) specific reference signals. The UE can use the T-RSs for fine time/frequency (T/F) tracking and Automatic Gain Control (AGC) adjustment of corresponding SCells resulting in reduced SCell activation latency compared to utilizing a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) Block Measurement Timing Configuration (SMTC).

Abstract: Some embodiments include a system, method, and computer program product for radio resource management (RRM) scaling factor enhancement without measurement gaps (MGs) in an E-UTRA-New Radio (NR) Dual Connectivity (EN-DC) network. Some embodiments include a user equipment (UE) that receives from a Primary Node (PN), a first NR measurement object (MO) without MG associated with a frequency. The UE receives from a Secondary Node (SN), a second NR MO without MG associated with the same frequency. The UE allocates resources based on a Primary Secondary Component Carrier (PSCC) and determines a scaling factor for determining a total procedure period for obtaining measurements to satisfy the first and the second NR MO without MG. Some embodiments include combining counts of NR MO without MG at a same frequency. Some embodiments include coordination between the PN and the SN so that MOs without MG at a common frequency satisfy the merging rule.

Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

Abstract: A next generation evolved Node B (gNB) configured to provide an unlicensed bandwidth for communications with a user equipment (UE) performs a listen-before-talk procedure to determine an occupation state of busy or idle for the unlicensed bandwidth. When the occupation state is determined by the gNB to be idle, the gNB signals the UE, via a downlink control indicator (DCI), to conduct a channel access measurement (CAM) on the unlicensed bandwidth, the measurement comprising at least one of an energy detection measurement or a signal quality measurement. A measurement report is received from the UE comprising an indication of the occupation state of the unlicensed bandwidth as determined by the UE.
