Moreover, the method includes receiving scheduling pattern indicating subframes and corresponding HARQ processes reserved for the LTE operation or derived DRX parameters from the base station based on the indication. | 2016-02-04 |
20160037547 | SYSTEMS, METHODS, AND DEVICES FOR DISTRIBUTED SCHEDULING FOR DEVICE-TO-DEVICE INTERFERENCE MITIGATION - Systems, methods, and devices for device-to-device (D2D) distributed scheduling are disclosed herein. User equipment (UE) is configured to measure a received power level for a reference signal received from a target UE and measure received power levels for reference signals received from one or more non-target UEs. The UE is configured to generate a resource usage map for the target UE and the one or more non-target UEs. The UE is configured to determine a priority, with respect to the target UE, for each resource element group based on the resource usage map and an anticipated signal-to-interference ratio (SIR). The UE is configured to transmit data to the target UE during one or more resource element groups with the highest priorities for the target UE. | 2016-02-04 |
20160037548 | MEASUREMENT METHOD, BASE STATION, AND USER EQUIPMENT - In a measurement method, a base station, and a user equipment, the measurement method includes: sending, by a base station, signaling to a user equipment, where the signaling carries node indication information, where the node indication information is used to indicate nodes corresponding to channel state information measurement sets configured by the base station for the user equipment. In this way, the user equipment can learn, according to the node indication information, the nodes corresponding to the channel state information measurement sets configured by the base station for the user equipment; then, the user equipment can measure the nodes corresponding to the channel state information measurement sets on the channel state information measurement sets configured by the base station for the user equipment and provide feedback, so that the base station can schedule the user equipment according to a measurement result of the user equipment. | 2016-02-04 |
20160037549 | METHOD FOR TRANSMITTING AND RECEIVING SIGNAL USING DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SAME - Disclosed is a method by which a representative terminal of a specific cluster performs scheduling for device-to-device (D2D) communication in a wireless communication system. Particularly, the method comprises the steps of: receiving a first signal from a terminal of a neighboring cluster; and comparing a priority given to the neighboring cluster with a priority given to the specific cluster in a specific resource among a plurality of resources so as to perform D2D communication scheduling on a component terminal of the specific cluster, wherein the first signal includes information on the neighboring cluster. | 2016-02-04 |
20160037550 | RADIO ACCESS NETWORKS - An example communication system in a cellular network comprises: a processing system comprising a controller and remote units, with the remote units being configured to communicate with the controller and to communicate with mobile devices within a communication cell of the cellular network. At least part of the processing system is configured to perform operations comprising: estimating signal strength experienced by all or some of the mobile devices; identifying, based at least on the signal strength, one or more of the mobile devices that can be scheduled for communication with one or more of the remote units in the communication cell on a same airlink resource; and scheduling the communication. | 2016-02-04 |
20160037551 | DOWNLINK TRANSMISSION SCHEDULING FOR USER EQUIPMENTS ENABLING DEVICE-TO-DEVICE COMMUNICATIONS - This disclosure generally relates to downlink transmission scheduling for D2D UE based on subframe pattern. In one embodiment, the D2D UE may provide the BS with information on a pattern of the D2D reception subframes that indicates the usage of at least some of the D2D reception subframes. From the pattern, the BS may determine one or more D2D reception subframes in which the UE wants to monitor the D2D reception and/or the cellular reception. Then the BS may avoid scheduling the downlink transmission in the subframes in which the UE monitors the D2D reception. In the other D2D reception subframes, the downlink transmission can be scheduled. In this way, the UE can properly switch between the D2D reception and cellular reception, without any conflicts or downlink resource waste. | 2016-02-04 |
20160037552 | METHOD AND APPARATUS TO ADAPT THE NUMBER OF HARQ PROCESSES IN A DISTRIBUTED NETWORK TOPOLOGY - A system includes a downlink transmitter unit, a downlink scheduler unit, and an uplink receiver unit. At least one of the units is located at a physically separate location from others of the units, and the at least one of the units communicates with the others of the units over a backhaul. A controller that allocates a number of hybrid automatic repeat request (HARQ) processes according to any communication delays caused by the backhaul. | 2016-02-04 |
20160037553 | LOW LATENCY WLAN MEDIUM ACCESS - A method and apparatus for managing access to a wireless medium by one or more stations (STAs) in a wireless network. A device determines a first transmit opportunity for a first STA of the one or more STAs in the wireless network. The device enables the first STA to access the wireless medium for a duration of the first transmit opportunity by broadcasting a first grant message to the one or more STAs in the wireless network. The first grant message indicates allocation of the first transmit opportunity to the first STA. The device may selectively adjust the duration of the first transmit opportunity based at least in part on one or more properties of the wireless network. | 2016-02-04 |
