  • Patent number: 9888487
    Abstract: Embodiments of the claimed subject matter provide embodiments of methods for supporting dynamic sub frame reconfiguration in a time division duplex wireless communication system. One embodiment includes transmitting, from a first base station to a second base station, a message indicating that the first base station is configured for scheduling uplink transmissions from first user equipment in one or more subframes of a time division duplex frame. The message is transmitted when the second base station is configured for downlink transmission to second user equipment in the subframe(s).

  • Publication number: 20170181189
    Abstract: A method includes: determining, by an AP from all STAs associated with the AP, a concurrent STA joining a concurrent group, and generating concurrent group information of the concurrent group; and sending the concurrent group information to another AP in a system other than the AP, so that a BSS to which the another AP belongs determines, according to the concurrent group information, to join the concurrent group, to eventually form the concurrent group. All concurrent STAs that are associated with the AP and that join the concurrent group perform channel contention within a concurrent time by using an increased target CCA threshold, to increase a possibility that the concurrent STAs send data, so that a system throughput is improved.

  • Patent number: 9538543
    Abstract: Methods and apparatuses for indicating an interference distribution in frame between base stations are provided. The method comprises: in response to a mismatch between a first frame allocation used by a first base station and a second frame allocation used by a second base station, transmitting, from the first base station to the second base station, a message for indicating an interference distribution in frame, A new information element, i.e., UL ABS (uplink Almost Blank Subframe) is introduced to indicate the uplink ABS information of the interfering base station. A modified DL ABS with a flag is used to indicate the downlink ABS information of the interfering base station, wherein the flag is to indicate that the DL ABS is used to protect UL transmission in the recipient base station.

  • Publication number: 20160057666
    Abstract: The present invention aims to provide method, apparatuses and systems for providing UE with biasing adjustment parameters about cell range expansion in a heterogeneous network. Herein, a current eNB determines, based on attribute information of one or more user equipments to be handed over, biasing adjustment parameters about cell range expansion of the one or more user equipments corresponding to their target eNB, and sends the biasing adjustment parameters to the one or more user equipments; the one or more user equipments adjust, based on the biasing adjustment biasing adjustment parameters, its report trigger condition of measurement report on measurement report on the current eNB and the target eNB, and report, the measurement report on the current eNB and the target eNB to the current eNB when the report trigger condition is satisfied; the current eNB makes a handover decision for corresponding user equipment(s) based on the measurement report.

  • Patent number: 9107068
    Abstract: The herein described device and method facilitate inter-cell interference coordination (ICIC) in a relay-assistant cellular network by: determining, with respect to a sector, whether the sector is relay overloaded or neighboring sectors of the sector are relay overloaded according to load information of the neighboring sectors of the sector; enabling the sector to borrow relay resources released by the neighboring sectors of the sector if the sector is relay overloaded with respect to the neighboring sectors of the sector; and releasing relay resources allocated to the sector according to load information of the neighboring sectors of the sector if the neighboring sectors are relay overloaded with respect to the sector.

  • Patent number: 9078255
    Abstract: The present application describes embodiments of methods and apparatuses for controlling communications within a first cell that is overlapped by a second cell. One embodiment of the method includes receiving a signal at the second cell indicating a number of devices selected to communicate with the first cell and identifying a set of subframes during which communications are permitted to take place within the first cell based on the number of devices selected to communicate with the first cell. This embodiment of the method also includes delivering an indication of the set of subframes to the first cell.

  • Publication number: 20150098368
    Abstract: The invention provides a method and apparatus for invoking a response of a current TDD subframe configuration. First, the first base station sends to the second base station a first message for invoking a response of a current TDD subframe configuration of the second base station. Second, the second base station receives the first message from the first base station and then sends to the first base station a second message in response to the first message, the second message including the current TDD subframe configuration of the second base station. Third, the first base station receives the second message from the second base station and acquires the current TDD subframe configuration of the second base station from the second message.

  • Publication number: 20150003272
    Abstract: Embodiments of the claimed subject matter provide a method and apparatus for transmitting an uplink overload indicator in a wireless communication system that operates according to time division duplexing. One embodiment of the method includes transmitting, from a first base station to a second base station, a message indicating that the first base station detected interference in at least one subframe of a time division duplex (TDD) frame allocated for reception of uplink signals at the first base station. A portion of the interference is generated by downlink transmissions from the second base station in the subframe of the TDD frame.
