CONNECTED MODE EXTENDED DISCONTINUOUS RECEPTION

摘要

Methods, systems, and devices for wireless communication are described. Wireless devices may operate in an extended connected discontinuous reception (eDRX) mode to increase energy efficiency and extend battery life. Control signaling may be used to initiate or support the extended sleep cycles associated with eDRX operation. In some cases, a system frame number (SFN) extension may be implemented to record frame cycles and differentiate SFNs that occur in a first frame cycle from SFNs that occur in a second frame cycle. Control techniques to support eDRX operation and maintain network synchronicity and compatibility may also be employed. In some examples, a wireless system may broadcast extended or dedicated system information updates to an eDRX capable device or devices. In some cases, devices may adjust the rate at which radio link monitoring (RLM) measurements are taken to timely determine radio link failures (RLFs) in conjunction with eDRX operation.

主权项

1. A method of wireless communication, comprising:
entering a connected mode by establishing a radio resource control (RRC) connection with a base station; determining a connected mode extended discontinuous reception (DRX) configuration comprising a low power period that is longer than a full system frame number (SFN) cycle; deactivating at least one radio component while in the connected mode for the low power period based at least in part on the connected mode extended DRX configuration; and activating the at least one radio component after the low power period based at least in part on the connected mode extended DRX configuration.
