Embodiments described herein relate generally to delaying the transmission of a plurality of data packets. A device may enter a packet-delay mode based on an absence of detected user activity and an idle state of a radio. In the packet-delay mode, the device may queue data packets in a buffer so that transmission of those data packets is delayed. The buffered data packets may be released and transmitted upon the occurrence of a predetermined event, such as detection of user activity, exceedance of a buffer threshold, or expiration of a countdown timer. Other embodiments may be described and claimed.

Embodiments of user equipment (UE) and methods for application-agnostic discontinuous reception (DRX) triggering are generally described herein. In some embodiments, a UE is configured to monitor buffer status history and traffic activity history, and trigger DRX mode activation based on the buffer status and the traffic activity history. In some embodiments, the UE may determine a probability, based on the buffer status history and the traffic activity history, that a level of traffic activity that cannot be handled during DRX mode would occur. In these embodiments, the UE may trigger DRX mode activation when the probability is below a threshold.

In typical UEs, scanning for WiFi access points (APs) can consume a significant amount of power. This scanning occurs when the UE is connected through the cellular network, but does not occur when the UE is connected to a WiFi network. As a result, offloading a UE from a cellular network to a WiFi network can allow the UE to conserve power. An issue with existing cellular networks is that the UE cannot inform a cellular network that the UE is running low on power, and therefore cannot direct the cellular network to offload the UE for power conservation reasons. A technique discussed herein allows the UE to indicate its power saving needs to the cellular network. In response, the cellular network can lower (or raise) a particular threshold, so that the UE now exceeds (or no longer exceeds) the threshold, and initiates offloading.

Embodiments of user equipment (UE) and methods for quality-of-experience (QoE) based discontinuous reception (DRX) in 3GPP LTE-A networks are generally described herein. In some embodiments, a UE is configured to select one of a plurality of DRX parameter sets based on current application requirements and send an indication to an enhanced Node B (eNB) to indicate the selected DRX parameter set. The UE may enter DRX mode in accordance with the selected DRX parameter set. Each DRX parameter set may include an on-duration time, a DRX cycle length, and a DRX inactivity timer. In some embodiments, each DRX parameter set may be associated with a DRX parameter set index, and the UE may indicate one of the DRX parameter set indices to the eNB to select an initial DRX parameter set or to request switching to a different DRX parameter set in response to changing application requirements.

Generally, this disclosure provides apparatus and methods for improved signaling of User Equipment (UE) assistance information in a wireless network. The UE device may include a processing circuit configured to generate an assistance information message including a power preference indicator (PPI) and mobility state information (MSI), the PPI and the MSI associated with the UE; a signal generation module configured to generate a Medium Access Control (MAC) layer Control Element (CE) signal, the MAC CE signal including the assistance information message; and a transmitter circuit configured to transmit the MAC CE signal to an evolved Node B (eNB) of a wireless network associated with the UE, the MAC CE signal transmitted on an uplink shared channel (UL-SCH). The assistance information message may also be generated as a Radio Resource Control (RRC) message and transmitted on an uplink dedicated control channel (UL-DCCH).

Embodiments of methods for optimizing power savings in a wireless device by maintaining sleep in sub-frames of an extended Listen Window, in an I.E.E.E. 802.16m communication system. In one embodiment, the Listen Window is extended into the Sleep Window, wherein at least one sub-frame remains designated for sleep. The power savings may be used when HARQ retransmissions are scheduled or for VoIP transmissions and so forth.

Embodiments of a mobile station and method for dynamically changing a sleep cycle are generally described herein. The mobile station is configured to dynamically switch a sleep cycle without deactivating a current power savings class (PSC). In some embodiments, the mobile station may generate a dynamic sleep-cycle switching message to request a change in the sleep cycle of the mobile station when changes in downlink traffic are detected. The dynamic sleep-cycle switching message may indicate either one of a plurality of predefined sleep cycles or may indicate parameters defining a new sleep cycle. This may allow the sleep cycle of the currently active PSC to be changed without deactivation.
摘要:
Technology is discussed for allowing a wireless mobile device, such as a User Equipment (UE), to coordinate with a Radio Access Network, such as an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN), to tear down a power intensive messaging connection, such as a Radio Resource Control (RRC) connection, to met needs of both the UE and the E-UTRAN. The UE can initiate the tear down process based on information at the UE about the potential need of the UE for the RRC connection and/or the state of the UE's battery charge. The E-UTRAN can then determine whether to grant the request based on the potential overhead involved. The determination can be important to the E-UTRAN because of the large overhead associated with frequent disconnection and re-establishment of the RRC connection. Upon receipt of an affirmative response, the UE can tear down the RRC connection to save battery power.

Embodiments described herein relate generally to a reliable delivery of a paging message in a wireless network environment. To prevent the unacceptable delay of delivery of a paging message to a UE, the number of paging opportunities that are to occur during a paging cycle may be increased. The UE may access a lookup table that indicates the paging opportunities for the paging cycle. The paging opportunities may correspond to subframes of the paging frame that include a paging message. The UE may then detect the paging message in a respective subframe of the paging frame that corresponds with a paging opportunity. Other embodiments may be described and claimed.
