Abstract:
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.
Abstract:
An apparatus and method for initiating discontinuous reception (DRX) operation in a user equipment (UE) are disclosed herein. Applications running on the UE are monitored by the UE to identify one or more inactivity trigger events associated with the application(s). The UE includes an application-radio cross layer to process the application information, including the inactivity trigger event, for use by a radio layer. The radio layer of the UE determines initiation of the DRX operation in accordance with the application information, including the inactivity trigger event, provided by the application-radio cross layer and device characteristics information.
Abstract:
Embodiments of Evolved Node-B (eNBs), user equipment (UE) and methods for licensed shared access (LSA) handover are generally described herein. An eNB includes hardware processing circuitry to receive a command to release spectrum resources in a LSA band over which the eNB serves an LSA cell; to determine whether user equipment (UEs) served by the eNB are permitted to skip a random access process (RAP) to be handed over to a target cell operating on a band separate from the LSA band; and to transmit a message to a UE served by the eNB instructing the UE that the UE is to be handed over to the target cell, the message including one or more indicators based on the determination. Other apparatuses, systems and methods are also disclosed.
Abstract:
Embodiments for signaling quality of service (QoS) requirements and user equipment (UE) power preference in LTE-A networks are generally described herein. In some embodiments, a power preference indication (PPI) is received at an eNB from a UE to set a power saving preference for the UE. A communication session is established using radio resource control (RRC) messages between the UE and the eNB to identify a preference for QoS configuration for handling traffic provided to the UE by the eNB. The QoS for traffic provided by the eNB to the UE is managed by the eNB based on the identified preference for QoS configuration for handling traffic provided to the UE.
Abstract:
Briefly, in accordance with one or more embodiments, a fixed device performs a cell search to search for one or more cells on a network and determines a transmit power level to communicate with one of the cells of the network. The fixed device sets a frequency of updating the transmit power level for communication with a cell on the network, wherein the frequency of updating the transmit power level is reduced for the fixed device with respect to a mobile device.
Abstract:
Embodiments of an Evolved Node-B (eNB) to support Carrier Aggregation (CA) of a licensed frequency band and an unlicensed frequency band are disclosed herein. The eNB may transmit traffic packets on an unlicensed channel in the unlicensed frequency band to one or more User Equipments (UEs) assigned to the unlicensed channel. The eNB may receive, on the licensed frequency band, interference indicators for the unlicensed channel from at least a portion of the UEs assigned to the unlicensed channel. In addition, the eNB may transmit, on the licensed frequency band, a multicast vacate channel control message for the unlicensed channel. The message may be for reception at one or more of the UEs assigned to the unlicensed channel.
Abstract:
Embodiments of an Evolved Node-B (eNB) to support Mission-Critical Machine Type Communication (MC-MTC) User Equipments (UEs) are disclosed herein. During a transmission notification (TN) monitoring period, the eNB may monitor for TN signals from MC-MTC UEs. When a presence of TN signals is detected, the eNB may refrain from allocation of dedicated MC-MTC traffic resources to other UEs for transmission during a traffic period. In response to a detection of an absence of TN signals from the first group of MC-MTC UEs during the TN monitoring period, the eNB may allocate the dedicated MC-MTC traffic resources to the other UEs for transmission during the traffic period. Starting times of the traffic period and the TN monitoring period may be spaced apart by a predetermined time difference. In some embodiments, the predetermined time difference for MC-MTC UEs may be not greater than 10 milliseconds.

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).

Apparatuses and methods for carrier aggregation are generally described herein. An evolved NodeB (eNB) may transmit downlink control information (DCI) on a control channel portion for a primary cell (PCell) downlink (DL) subframe. The DCI can include an offset field indicating an offset, relative to a first secondary cell (SCell) subframe, to identify a second SCell subframe for which the DCI is providing control information. Other apparatuses and methods are also described.
