20150043515 | RADIO COEXISTENCE IN WIRELESS NETWORKS - Technology for avoiding in-device coexistence (IDC) interference between multiple radio transceivers at a user equipment (UE). The UE may identify a subframe with substantially no IDC interference from one or more of the multiple radio transceivers at the UE. The UE may determine that the subframe with substantially no IDC interference occurs during an unscheduled period of a Discontinuous Reception (DRX) cycle for the UE. The UE may perform Radio Link Monitoring (RLM) during the subframe with substantially no IDC interference during the unscheduled period of the DRX cycle for the UE. | 02-12-2015 |
20150092641 | COMMUNICATION OF PREFERRED POWER CONSUMPTION CONFIGURATIONS - Technology for communicating power preference indication (PPI) message is described. A user equipment (UE) may receive PPI configuration information, from an evolved node B (eNB), wherein the PPI configuration information includes a predetermined threshold for a number of PPI messages that the UE can communicate to the eNB during a defined time window. The UE may communicate a plurality of PPI messages after sending a low power consumption configuration to the eNB during the defined time window, wherein the plurality of PPI messages each indicate a change in preferred power consumption configuration. The UE may detect that the plurality of PPI messages exceeds the predetermined threshold for the number of PPI messages that the UE can communicate to the eNB during the defined time window as defined in the PPI configuration information. The UE may initiate a threshold timer in response to the plurality of PPI messages exceeding the predetermined threshold to restrict additional PPI messages from being communicated to the eNB until expiration of the threshold timer. | 04-02-2015 |
20150146599 | COORDINATION TECHNIQUES FOR RADIO RESOURCE CONTROL STATE MANAGEMENT IN DUAL-CONNECTIVITY ARCHITECTURES - Coordination techniques for radio resource control state management in dual-connectivity architectures are described. In one embodiment, for example, a master evolved node B (MeNB) may comprise logic, at least a portion of which is in hardware, the logic to send an inactivity notification message to indicate an expiration of an RRC_Inactivity_Timer for a dually-connected user equipment (UE), receive a state decision message in response to the inactivity notification message, and determine whether to transition the dually-connected UE to an RRC_Idle state based on the state decision message. Other embodiments are described and claimed. | 05-28-2015 |
20150195796 | POWER HEADROOM REPORTING WITH DUAL CONNECTIVITY - Embodiments described herein relate generally to a communication between a user equipment (“UE”) and a plurality of evolved Node Bs (“eNBs”). A UE may be adapted to operate in a dual connected mode on respective wireless cells provided by first and second eNBs. The UE may be adapted to estimate respective power headroom (“PHR”) values associated with simultaneous operation on the first and second wireless cells. The UE may cause the first and second PHR estimates to be transmitted to both the first and second eNBs. The first and second eNBs may use these estimates to compute respective uplink transmission powers for the UE. Other embodiments may be described and/or claimed. | 07-09-2015 |
20150245349 | ENHANCEMENT TO THE BUFFER STATUS REPORT FOR COORDINATED UPLINK GRANT ALLOCATION IN DUAL CONNECTIVITY IN AN LTE NETWORK - Technology for efficiently splitting a bearer at the packet data convergence protocol (PDCP) layer for uplink (UL) data transfers in wireless networks where dual connectivity is available is disclosed. A user equipment (UE) can send buffer status reports (BSRs) to a master evolved node B (MeNB) and a secondary evolved node B (SeNB). The BSRs can be formatted such that the amount of data in a radio link control (RLC) buffer at the UE and the amount of data in a packet data convergence protocol (PDCP) buffer at the UE are contained in different fields. The BSRs can also contain redundancy indicator (RI) values specifying a redundancy level between the PDCP buffer amounts included in the BSRS. The MeNB and the SeNB may then coordinate, via an X2 interface, an amount of uplink (UL) resources to allocate to the UE. | 08-27-2015 |
20150264511 | EFFICIENT COORDINATION BETWEEN A 3GPP NODE AND MTC DEVICES FOR COVERAGE ENHANCEMENT MODE - Systems and methods provide coordination between a 3GPP node and user equipment (UE) for coverage enhancement modes (OEM). At predetermined reference times, the node enters OEM and broadcasts dynamic OEM scheduling information. A UE with OEM capability may attempt to connect to the node at the predetermined reference times and other times indicated in the dynamic OEM scheduling information. | 09-17-2015 |
20150264621 | SYSTEMS AND METHODS FOR JOINT HANDOVER OF USER EQUIPMENT AND SECONDARY CELL GROUP IN 3GPP LTE DUAL CONNECTIVITY - Systems and methods provide a joint handover process wherein a user equipment (UE) and at least one secondary node remain connected to each other and are handed over together from a first master node to a second master node. Thus, a re-establishment procedure with the at least one secondary node is avoided. | 09-17-2015 |
20150289251 | USE OF SCHEDULING REQUEST AND RANDOM ACCESS FOR LTE ADVANCED NETWORKS - Methods and apparatus for communicating in a wireless network include mechanisms to facilitate concurrent use of periodic scheduling requests and a random access procedure for a UE to request uplink resources from an eNB. | 10-08-2015 |
