Abstract

Embodiments of techniques and systems for extended discontinuous reception (DRX) are described herein. In some embodiments, a user equipment (UE) configured for extended DRX may include receiver circuitry and paging circuitry. The receiver circuitry may be configured to receive a system frame number from an eNB and receive extension data from the eNB. The paging circuitry may be configured to determine an augmented system frame number based on the system frame number and the extension data, determine a paging frame number based on the extension data, and monitor for paging occasions when the augmented system frame number is equal to the paging frame number. Other embodiments may be described and/or claimed.
