Abstract: Embodiments of user equipment (UE) and method for discontinuous reception (DRX) mode in wireless communication are generally described herein. In some of these embodiments, the UE may operate to determine a value for a DRX parameter based at least in part on information associated with an application running on the UE. The UE may send a message to an enhanced node-B (eNB). The message may include at least one of the value for the DRX parameter and the information associated with the application. The eNB may determine values for DRX parameters that the UE may use in DRX mode.

Abstract: Described herein is a technique for aggregating background traffic packets by the background users instead of performing a random access procedure to request an uplink resource for each new packet. Since the same physical random access channel (PRACH) resources are used for random access procedures by multiple UEs, collisions can occur. The PRACH is expected to operate with very low collision rates, but if the number of users increases, the collision rate increases as well as the error rate. The disclosed technique reduces the collision rate by reducing the number of random access procedures used to transmit background traffic.

Abstract: Embodiments of the present disclosure describe systems and methods for operation of an evolved node B to provide multiple coverage enhancement levels. Various embodiments may include an operational mode configured to provide a first coverage enhancement level associated with user equipments (UEs) that have established communication with the eNB. These embodiments may also include a discovery mode configured to operate at a second coverage enhancement level to discover UEs configured for a higher coverage enhancement level. Other embodiments may be described and/or claimed.

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: Embodiments disclosed herein relate to devices and methods that provide adaptive CRE-based offset parameters that take into account the speed of a UE and that take into account the DL/UL traffic balance being experienced by the UE. For example, if the speed of a UE is greater than the predefined speed, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Similarly, if the balance of downlink/uplink traffic being experienced by a UE is mainly downlink traffic, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Consequently, the embodiments disclosed herein reduce the handover failure associated with CRE particularly for high speed UEs while also being able to increase downlink system capacity if the balance of the downlink and uplink traffic experienced by the UE is mostly downlink traffic.

Abstract: In embodiments, apparatuses, methods, and storage media may be described for monitoring channel quality of a radio link between a secondary evolved NodeB (SeNB) and a user equipment (UE) in a wireless communication network configured for dual connectivity. In embodiments, the UE may generate one or more indications of a channel quality of the SeNB-UE radio link and forward the indication to the SeNB. Based on the indication, the UE may receive a radio resource control (RRC) message from a master eNB (MeNB) related to the SeNB-UE radio link. Other embodiments may be claimed.

Abstract: Embodiments of a system and method to identify and differentiate background traffic are generally described herein. In some embodiments, a transceiver is arranged to wirelessly transmit and receive packets over a communications network and a processor, coupled to the transceiver, is arranged to provide an indication identifying packets associated with background traffic. The indication identifying packets associated with background traffic includes a bit in a header of a packet, wherein the bit is set in a first state to indicate the packet is associated with background traffic and the bit is set in a second state to indicate the packet is associated with active traffic, or an identification of a port number and a protocol type associated with background traffic. The processor is further arranged to provide an indication for differentiating background traffic.

Abstract: 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.

Abstract: 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.

Abstract: Techniques are described that can be used to determine a transmitter power level of a mobile station at cell edge. To determine transmitter power level, the technique considers at least a balance of power transmitted by mobile stations near cell edge and power transmitted by mobile stations closer to cell center, target mean received power by the base station from mobile stations near center cell, target mean power transmitted from cell edge mobile stations, signal-to-interference-power ratio between signals transmitted from base stations of different cells to the mobile station at cell edge, and channel gain.

Abstract: Embodiments of an OFDMA cellular network and method for mitigating interference are generally described herein. In some embodiments, the scheduler assigns a common group ID to mobile stations based on interference levels of a common interference source and allocates bandwidth within a selected zone of an OFDMA uplink subframe to the mobile stations assigned the common group ID for uplink communications within the uplink subframe. In some joint-scheduling embodiments, a neighbor base station that is identified as the common interference source may refrain from assigning bandwidth within the selected zone to at least some of its associated mobile stations that have identified the serving base station as an interference source.

Abstract: Methods and apparatuses enable sending a fast access request in a preamble of a random access request. The fast access request provides for an uplink assignment having bandwidth sufficient to allow the transmission of data with a scheduling request. The fast access request can indicate, for example, a traffic class of a message to be sent. Based on traffic class information, up to a certain additional amount of bandwidth can be allocated for a scheduling procedure for the requesting user device.
