If a cell, represented by a macro eNB for example, is muting resources, those resources can be made available, under appropriate conditions, to user devices, such as UEs, engaging in device to device communication. Allocation of muted resources to D2D UEs can be based on meeting of conditions, such as that the D2D UEs be outside of a specified proximity to a cell, such as a small cell, using the resources, or that the D2D UEs transmit at less than a specified power. The UEs may take measurements to determine if the conditions are met and report the measurements to their base stations, which then determine whether to allocate the muted resources and configure the UEs with resource allocation information.

  • Patent number: 10159023
    Abstract: A method in a wireless communication network for assisting a user equipment to receive signals from a target access node. The wireless communication network comprises the target access node, the user equipment and a serving access node serving the user equipment. The serving access node sends information about time instances to the user equipment. The time instances are scheduled for sending signals from the target access node in a beam direction towards the user equipments. The time instances may be determined in the target access node based on its own position and a position of the user equipment and/or a beam direction of the serving access node. The time instances may also be determined in the serving access node based on its own position and a schedule of the target access node on beam directions versus transmission times. The user equipment receives signals from the target access node during the time instances indicated in the received information.

    Abstract: A communication quality determination/acquisition device and method for a wireless communication system. The determination device includes: a measuring module configured to perform downlink channel quality measurement based on a distribution of static and dynamic downlink subframes of a target cell, wherein the static downlink subframes are downlink subframes relative to the target cell and at least one neighboring cell, while the dynamic downlink subframes are downlink subframes relative to the target cell and are uplink subframes relative to the at least one neighboring cell; and a communication module configured to report a downlink channel quality measurement result. By performing measurement and reporting while considering downlink subframe configurations and the distribution of the static and dynamic downlink subframes of the target cell, the device and method can accurately measure the channel quality under dynamic TDD UL/DL configurations and report the same to a network side.

  • Patent number: 10148588
    Abstract: Implementations are provided herein for offering partitioned performance within a distributed file system and providing throttling at the granular level. A set of hardware and network resources available to process work items can be determined. A set of resource accounting tokens based on resource records generated when processing work items can be dynamically updated. A granular resource accounting aggregate for a customizable field of data can be selected for throttling, such as a unique user identifier, a unique group identifier, a unique client internet protocol address, a unique file, etc. A granular throttling level can then be established based on a granular throttling policy. In response to the resource accounting aggregate meeting the throttling level, the user, group, internet protocol address, etc. can be throttled at, at least one of, the cluster layer, the node layer or the protocol layer.

  • Patent number: 10135493
    Abstract: In a system for controlling a radio base station, an out-of-band emergency channel based on a power cable is established between a BBU and an RRU, so that even if a unique communications interface CPRI between the BBU and the RRU is abnormal, the BBU can still effectively control the RRU using the out-of-band emergency channel. In another system for controlling a radio base station, out-of-band emergency channels based on power cables are established among multiple RRUs, so that even if a unique communications interface CPRI between a BBU and a target RRU is abnormal, the BBU can still effectively control the target RRU using an out-of-band emergency channel between any RRU (a unique communications interface CPRI of the RRU is normal) and the target RRU. In the present disclosure, the BBU can effectively control the RRU.

  • Patent number: 10123317
    Abstract: A method is presented for receiving an Enhanced Physical Downlink Control Channel (EPDCCH) from a base station by a User Equipment (UE) in a wireless communication system. The UE receives the EPDCCH by monitoring EPDCCH candidates comprising one or more Enhanced Control Channel Elements (ECCEs), in a first time-frequency resources configured for the EPDCCH. Each of the one or more ECCEs comprises a plurality of Resource Element (RE) sets distributed in a second time-frequency resources within the first time-frequency resources. Indexes of the second time-frequency resources of including the plurality of RE sets are determined based on a specific value obtained by dividing a number of the first time-frequency resources by a number of the plurality of RE sets in the each of one or more ECCEs.

  • Patent number: 10116406
    Abstract: A method is described for reducing interferences in a wireless network, by: identifying cells which experience more interference than others; identifying a group of PRBs that their transmissions are subjected to more interference than other concurrent transmissions; identifying UEs associated with the group of PRBs, and determining whether the location of the UEs is at the cells' edges; selecting a pair of UEs where one member is located at a first cell's edge and the other is located either (i) at a second cell, not included within a neighbors' list of the first cell, or (ii) at the core or remote edge of a second cell. In case (i), the second cell is introduced to the first cell neighbors' list, and in case (ii) the other UE is falsely defined as a UE located at the near second cell's edge. Then, ICIC procedure is invoked for that pair of UEs.
