    摘要： The present invention relates to a method for downlink common pilot configuration for a base station serving a first set of User Equipments UEs and a second set of UEs, wherein the first set of UEs consists of 4-branch MIMO capable UEs and the second set of UEs consists of 4-branch MIMO mode incapable UEs, The method comprises the steps of determining (S410) information related to the UEs served by the Base Station BS; and configuring (S420) transmission of at least one common pilot from the BS to the served UEs based on the determined UE related information.In an example 4-branch MIMO system, at most 4 common pilots are configurable to be transmitted, and the at least one common pilot is two common pilots newly introduced into a legacy system. The present invention also relates to a base station configured for performing the method for downlink common pilot configuration and a computer readable storage medium. (Figure 4b)

    摘要： Network node (110), and method (300) in a network node (110), for load control in a cell (130) in a wireless communication system (100). The method (300) comprises starting an interference cancellation process, for reducing interference between uplink signals, estimating an interference cancellation gain, relative to an interference reduced received uplink signal power resulting from the interference cancellation process, wherein the interference cancellation gain is estimated after the start of the interference cancellation process but before the interference cancellation process is completed. In addition, the method (300) comprises controlling the traffic load of the cell (130), by considering the estimated interference cancellation gain.

    摘要： The present disclosure provides an uplink intra-frequency load balancing method. The uplink intra-frequency load balancing can be performed by adjusting a beam direction of a User Equipment UE. For each of UEs, the method comprises steps of: determining a cell load level of each cell based on an uplink load measurement received from base stations of a plurality of cells; determining a beam-forming capability of the UE based on a beam-forming gain of the UE; and calculating a cell balancing parameter for each of the plurality of cells, according to a common pilot channel CPICH quality report measured by the UE, the cell load levels of the plurality of cells and the beam-forming capability of the UE, so as to determine a beam-forming control cell towards which the beam direction of the UE is directed, the beam-forming control cell being a cell which has an optimal cell balancing parameter among the plurality of cells. The present disclosure further provides, for a UE which supports a CLBF mode but is not in the CLBF mode, a method for selectively activating the CLBF mode so as to enhance the effect of load balancing. The present further provides an uplink intra-frequency load balancing apparatus.

    摘要： Embodiments herein relate to a method in a radio base station (12) for estimating a noise floor in a cell (15) of a radio communications network. The radio base station (12) is comprised in the radio communications network and serves the cell (15) in the radio communications network. The radio base station (12) determines a time interval in which time interval the noise floor in the cell (15) is to be estimated. The radio base station further reduces a first interference during the determined time interval in the cell (15) and then measures a second interference in the cell (15) at a time in the time interval in the cell 15. The radio base station then estimates the noise floor using the measured second interference.
