摘要

A plurality of resource pools and/or a plurality of transmission and/or reception points may be used in wireless communications. Different pathloss references may be used for different resource pools and/or different transmission and/or reception points. A wireless device may receive one or more messages indicating a plurality of power control parameter sets each associated with a respective resource pool and/or a respective transmission and/or reception point. The wireless device may control a transmission power based on a pathloss reference associated with a resource pool and/or a transmission and/or reception point.

說明書

A base station storing an RRC context for a wireless device or a last serving base station of the wireless device may be referred to as an anchor base station. An anchor base station may maintain an RRC context for the wireless device at least during a period of time that the wireless device stays in a RAN notification area of the anchor base station and/or during a period of time that the wireless device stays in an RRC inactive state (e.g., RRC inactive 604).

A base station (e.g., gNBs 160 in FIG. 1B or any other base station) may be split in two parts: a central unit (e.g., a base station central unit, such as a gNB CU) and one or more distributed units (e.g., a base station distributed unit, such as a gNB DU). A base station central unit (CU) may be coupled to one or more base station distributed units (DUs) using an F1 interface (e.g., an F1 interface defined in an NR configuration). The base station CU may comprise the RRC, the PDCP, and the SDAP layers. A base station distributed unit (DU) may comprise the RLC, the MAC, and the PHY layers.
