    摘要： Systems and methods are disclosed for controlling cell selection between a high power base station and a neighboring low power base station in a cellular network. In one embodiment, a primary direction of traffic flow for a user equipment located within a transition zone between a high power base station cell of the high power base station and a low power base station cell of the low power base station is determined to be either an uplink direction or a downlink direction. Cell selection for the user equipment is then controlled based on the primary direction of traffic flow for the user equipment such that selection of the high power base station cell is favored if the primary direction of traffic flow is the downlink direction and selection of the low power base station cell is favored if the primary direction of traffic flow is the uplink direction.

    摘要： Methods of communicating with a selected user equipment terminal (UE) in a first cell served by a base station and a remote radio head include forming a list of non-targeted UEs including other UEs in the first cell and cell edge UEs in a neighboring cell that borders the first cell that are located near a border of the first cell and the neighboring cell, generating a list of candidate precoding matrices that can be used to communicate with the selected UE from the base station and/or from the remote radio head, generating a list of available precoding matrices by discarding from the list of candidate precoding matrices those precoding matrices that may cause interference to at least one non-targeted UE, selecting a precoding matrix from the list of available precoding matrices, and communicating with the selected UE using the selected precoding matrix.
