1. A computer-implemented method comprising:
- establishing, at an evolved node B (eNB) configured to support a serving cell for user equipment and arranged to operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards to include LTE-Advanced (LTE-A), a first time division duplex (TDD) configuration associated with communications to the user equipment;
receiving TDD configuration information for one or more other serving cells indicating at least one of the one or more other serving cells has established a second TDD configuration associated with communications to the user equipment that is different from the first TDD configuration;
defining one or more discontinuous reception (DRX) timers associated with temporarily powering on or off receiver circuitry at the user equipment based on the first and second TDD configurations, the one or more DRX timers comprising a drx-InactivityTimer; and
defining a first definition for the drx-InactivityTimer based on the first TDD configuration and a second definition for the drx-InactivityTimer based on the second TDD configuration.

Abstract
Examples are disclosed for timers associated with powering receiver circuitry at a wireless device or user equipment. The examples include separately defining one or more timers based on different time division duplex (TDD) configurations. The different TDD configurations may be used for communications between user equipment and serving cells supported by one or more base stations such as evolved node Bs (eNBs) in a Long Term Evolution (LTE) wireless network. The defined timers may be used by the user equipment to selectively power receiver circuitry. Other examples are described and claimed.

15. An apparatus comprising:
-
a processor circuit for a an evolved node B (eNB) arranged to support a first serving cell for user equipment and arranged to operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards to include LTE-Advanced (LTE-A); a configuration component arranged for execution by the processor circuit to establish a first time division duplex (TDD) configuration for communicatively coupling to the user equipment via the first serving cell; a receive component arranged for execution by the processor circuit to receive TDD configuration information for a second serving cell that indicates the second serving cell has established a second TDD configuration for communicatively coupling to the user equipment that is different than the first TDD configuration; and a timer component arranged for execution by the processor circuit to define one or more discontinuous reception (DRX) timers associated with temporarily powering on or off receiver circuitry at the user equipment based on the first and second TDD configurations, the timer component arranged to define separate sets of DRX timers to include a first set of DRX timers based on the first TDD configuration and a second set of DRX timers based on the second TDD configuration. - View Dependent Claims (16, 18, 19, 20, 21)

17. The apparatus of 15, the first set of DRX timers and the second set of DRX timers to separately include an onDurationTimer, a drx-RetransmissionTimer and a drx-InactivityTimer, definitions for the DRX timers defined by the timer component for the first set of DRX timers being different than definitions for the DRX timers defined by the timer component for the second set of DRX timers.

22. At least one machine readable medium comprising a plurality of instructions that in response to being executed on a system for user equipment configured to operate in compliance with one or more or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards to include LTE-Advanced (LTE-A) causes the system to:
-
receive a first set of discontinuous reception (DRX) timers associated with powering receiver circuitry arranged to receive data from a first serving cell using a first time division duplex (TDD) configuration; receive a second set of DRX timers associated with powering receiver circuitry arranged to receive data from a second serving cell using a second TDD configuration; responsive to receiving data from the first serving cell, selectively powering on or off the receiver circuitry based on the first set of DRX timers; and responsive to receiving data from the second serving cell, selectively powering on or off the receiver circuitry based on the second set of DRX timers. - View Dependent Claims (23, 24, 25, 26)
