  • Patent number: 9894535
    Abstract: A wireless device accesses a shared spectrum equitably in a self-organizing manner by determining success indices and adjusting courtesy parameters. The wireless device transmits wireless transmissions in a frame subframe structure over a shared spectrum, each of the subframes bounded by subframe boundaries at predetermined time intervals. The success index represents a measure of success in transmitting wireless transmissions in the shared spectrum. The wireless device performs a clear channel assessment to determine whether the shared spectrum is available at the end of the clear channel assessment time interval. The wireless device determines a gap interval between the end of the clear channel assessment time interval and the next subframe boundary and transmits the success index during the gap interval.

  • Patent number: 9668265
    Abstract: Techniques for mitigating interference in a wireless communication network are described. A terminal may desire to communicate with a weaker serving base station and may observe high interference from a strong interfering base station. The two base stations may be asynchronous and have different frame timing. In an aspect, high interference may be mitigated by having the interfering base station reserve downlink and/or uplink resources. The interfering base station may transmit at a low power level or not at all on the reserved downlink resources to reduce interference to the terminal. Terminals served by the interfering base station may transmit at a low power level or not at all on the reserved uplink resources to reduce interference at the serving base station. The terminal may then be able to communicate with the serving base station.

  • Patent number: 8958809
    Abstract: A radio access network, such as an LTE E-RAN, employs a hierarchical architecture and includes a services node that provides connectivity between the radio nodes in the RAN and a core network. The RAN employs a hybrid coordinated scheduling scheme in which independent schedulers are running on the services node and the radio nodes. In this way the services node can allocate scheduling resources for some of the UEs in the RAN while the radio nodes can allocate scheduling resources for the remaining UEs in their respective serving cells. In some cases a prioritization approach is used in which the radio nodes do not schedule any radio resources that have already been scheduled by the services node.

  • Patent number: 8954085
    Abstract: A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.

  • Patent number: 8948124
    Abstract: The capacity of a cellular wireless system is increased by operation of base stations or base station sectors arranged to re-use radio resource elements that are used by neighboring base stations or base station sectors, in conjunction with operation of relay stations, which are similarly arranged to re-use radio resource elements used by neighboring relay stations, and where the radio resource elements re-used by the relay stations are different to those used by the base stations. The relay stations provide coverage, particularly in the areas at the boundaries between the areas of coverage of base stations that suffer from interference between signals transmitted from the respective base stations. In addition, the relay stations generally increase the average available carrier to interference ratio compared with a system in which base stations alone are deployed.

  • Patent number: 8948769
    Abstract: A method and an arrangement in a radio network node for adapting transmission power of resource elements for demodulation reference signals, referred to as “reference elements” are provided. The radio network node is configured for multiple-input multiple-output transmission, referred to as “MIMO transmission”, to a user equipment. The MIMO transmission comprises at least three layers. Two consecutive subcarriers of a resource block carry at least three reference elements. A first subcarrier of the resource block carries data elements. The radio network node adapts transmission power of said at least three reference elements such that an average transmission power, over said two consecutive subcarriers, of said at least three reference elements is equal to a transmission power, for the first subcarrier, of the data elements for said at least three layers. The radio network node uses the adapted transmission power to transmit, to the user equipment, said at least three reference elements.

    Abstract: Apparatus and methods are disclosed for mitigating interference to radio base stations. A first base station provides a served cell that at least partially overlaps a served cell of a second base station. The first and second base stations are part of a telecommunications system. The method includes identifying at least one carrier that is preferable for the second base station to utilize for communications with at least one UE to avoid interference. The method further includes communicating an instruction message from the first base station to the second base station that instructs the second base station to use the at least one carrier for communications.

  • Patent number: 8942713
    Abstract: Methods, systems and apparatus for dispersing a group of user equipment (UEs) concentrated on a single channel is disclosed. After receiving a disperse command the UEs select a channel, and then select a cell. The channel selection may be performed using a random or pseudorandom function. The cell selection may be performed prior to camping on the cell. Prior to camping the UEs may test the acceptability of a candidate cell and/or may perform a cell reselection. The result of the dispersion is that the UEs are distributed amongst many channels (a, b, c, and d), where reference are found in FIGS. 1A and 1B.

  • Patent number: 8929905
    Abstract: A method and apparatus for requesting and allocating bandwidth in a broadband wireless communication system. The method and apparatus includes a combination of techniques that allow a plurality of CPEs to communicate their bandwidth request messages to respective base stations. One technique includes a “polling” method whereby a base station polls CPEs individually or in groups and allocates bandwidth specifically for the purpose of allowing the CPEs to respond with bandwidth requests. The polling of the CPEs by the base station may be in response to a CPE setting a “poll-me bit” or, alternatively, it may be periodic. Another technique comprises “piggybacking” bandwidth requests on bandwidth already allocated to a CPE. Currently active CPEs request bandwidth using unused portions of uplink bandwidth that is already allocated to the CPE. The CPE is responsible for distributing the allocated uplink bandwidth in a manner that accommodates the services provided by the CPE.

  • Patent number: 8923906
    Abstract: A method, a user terminal and a network side equipment for improving network resource occupation are disclosed. A dormancy timer is set for the user terminal and a time threshold of the dormancy timer is adjusted dynamically by monitoring a resource occupation rate of the communication system, where time threshold of the dormancy timer is inversely proportional to the resource occupation rate. In this way, relatively longer time threshold of the dormancy timer may be set when a system occupation rate is low, so as to improve user experience; and relatively shorter time threshold of the dormancy timer may be set when the system occupation rate is high, so as to provide a higher capacity and provide services for more user terminals.
