RRM MEASUREMENT AND REPORTING FOR LICENSE ASSISTED ACCESS

摘要

Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

主权项

1. A method of wireless communication, comprising:
receiving, at a user equipment (UE), a radio resource management (RRM) measurement configuration for one or more frequency channels of a shared frequency band, the RRM measurement configuration comprising at least one channel occupancy measurement parameter for the one or more frequency channels; determining at least one channel occupancy metric for the one or more frequency channels according to the at least one channel occupancy measurement parameter; and reporting, to a serving cell, the at least one channel occupancy metric.
