  • Publication number: 20210314963
    Abstract: A method and an apparatus are provided for receiving resource allocation information by a user equipment (UE) in a wireless communication system. Channel state information (CSI) is transmitted to a first base station. The resource allocation information indicating resources for a first zone to the UE is received from the first base station, when the UE enters the first zone among a plurality of zones within a cell coverage of the first base station. Additional resource allocation information indicating additional resources for a second zone are received from a second base station, if it is estimated that the UE might enter the second zone among the plurality of zones based on a status of the second zone and a moving direction of the UE. The additional resources are received in response to a message, transmitted from the first base station, to the second base station, requesting the additional resources.

  • Patent number: 10524270
    Abstract: Examples implementations relate to contention-based resource allocation. In some examples, a method can include determining a station of stations associated with an access point having a contention window value or a resource value less than a total amount of resource units (RU) of a particular protocol data unit (PCU) of the access point, and allocating a RU of the RUs to the determined station based on a user parameter equal to a lesser of the resource value or a value of a RU limit of the determined station.

  • Patent number: 10257842
    Abstract: A method and an apparatus for providing zone based prediction. The method includes determining, by a base station, a plurality of zones by dividing a coverage area of a cell, receiving, by the base station, channel state information (CSI) from a user equipment (UE), identifying, by the base station, a first zone from the plurality of zones where the UE encounters an obstructed area based on the CSI at a time domain, and allocating, by the base station, at least one resource to the UE to compensate for signal losses if the UE enters the obstructed area.

  • Patent number: 9900838
    Abstract: A method and system for selecting an optimal DRX configuration for a User Equipment (UE) in a communication network is provided. An expression for expected maximum delay experienced by a packet arriving during the off-duration is derived for any packet arrival process (either known arrival process or unknown arrival process). Further, the method for computing the active duration in any DRX cycle with the expected delay to be less than a given threshold by considering all the timers in the communication network is provided. The DRX cycle configuration with minimum active duration is selected as optimal DRX configuration by the UE and UE informs the optimal DRX configuration to the network.
