    Abstract: A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) and a primary secondary cell (PSCell) of a wireless network, wherein a primary component carrier (PCC) of the PCell and a primary secondary component carrier (PSCC) of the PSCell are both in frequency range 1 (FR1). The UE receives a PCC measurement object (MO) configuration, a PSCC MO configuration, and an inter-frequency MO with no measurement gap configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an inter-frequency MO with no measurement gap CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap to determine a scaled measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap.

    Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig indicates up to L CSI reference signal (CSI-RS) ports for selection by the UE out of P CSI-RS ports configured for measuring and reporting CSI. The UE determines selected CSI-RS ports out of the P CSI-RS ports. The selected CSI-RS ports include the L CSI-RS ports or less. The UE generates a port selection matrix W1 corresponding to the selected CSI-RS ports. The UE also generates an indication of the port selection matrix W1 to the base station. The CSI-ReportConfig may further configure the UE to select a subset of frequency basis. The UE determines a selected subset of frequency basis and generates a frequency basis selection matrix Wf corresponding to the selected subset of frequency basis.

    Abstract: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.

    Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, during a random access procedure, a user equipment (UE) may receive a grant of resources for an uplink (UL) data transmission in a random access response (RAR) message. The UE may identify a scheduled slot for the UL data transmission based on a received slot of the RAR message and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified using the various techniques described herein.

    Abstract: Apparatus and methods are provided for port selection codebook configuration. A user equipment (UE) may decode a channel state information (CSI) report configuration (CSI-ReportConfig) from a base station. The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI. For the frequency basis selection matrix Wf, the UE determines up to Mv frequency basis out of N frequency basis. For the combinational coefficient matrix W2, the UE determines up to L*Mv entries per layer. The UE reports one or more of the port selection matrix W1, the combinational coefficient matrix W2, and the frequency basis selection matrix Wf to the base station.
