  • 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.

  • Patent number: 9949209
    Abstract: Power management in a distributed communications system, such as a distributed antenna system (DAS), that includes determining user activity at remote units of the DAS. When user activity in one or more remote units falls below or above a specified threshold, power usage by the one or more remote units is reduced or increased accordingly. The power usage may reduced and/or increased by turning select remote units on or off, by increasing or reducing an operating voltage of one or more power amplifiers, and/or by turning select multiple-in, multiple-out (MIMO) front ends on or off. Power may be reduced such that wireless coverage within a specified area is maintained.

  • Patent number: 9942865
    Abstract: Disclosed are a method and a device for synchronously counting a multimedia broadcast multicast service (MBMS) service. Through technical solutions of embodiments of the present invention, synchronization time point information is carried in a message sent to a base station by an MBMS coordinating entity (MCE), so that the base station counts the MBMS service at the corresponding synchronization time point, collects the counting information and feeds back the counting information to the MCE. Whereby, the base station can count the MBMS service for each terminal device served by the base station at the same time point and collect and transmit the MBMS service counting information to the MCE, thereby ensuring synchronization of MBMS service counting time, ensuring synchronization of multicast control channel (MCCH) contents at the air interface, and solving the problem that synchronization of MBMS service counting time cannot be ensured in the prior art.
