摘要： The present disclosure relates to an uplink congestion control scheme. In one embodiment, an uplink congestion control method is provided, comprising steps of: determining whether or not a congestion status of a serving cell is changed based on a rise over thermal, RoT, measurement; sending to a set of user equipment, UEs, a signaling to indicate the change of the congestion status; and performing an uplink congestion control based on the RoT measurement and with enhanced transmission format combination, E-TFC, reselection by at least one UE from the set of UEs based at least on the signaling.

摘要： An RBS and a method performed by an RBS for scheduling uplink resources to at least one UEare provided. The RBS comprises at least two receiving antenna branches and the RBS is operable in aradiocommunication network.The method comprises receiving (110) transmissions from the at least one UE by means of the at least two receiving antenna branches; and determining (120) at least one parameter relating tosignal quality of the received transmissions. The method further comprises determining (130) a diversity gain of the at least two receiving antenna branches, wherein the diversity gain is determined based on the determined parameter(s); and scheduling (140) uplink transmissions for the at least one UE based on the determined diversity gain.

摘要： The embodiments herein relates to a method in a base station (101) for transmitting an UpLink Transmit Power Control, UL TPC, command to a user equipment (103) in a communications network (100). The base station (101) obtains a measurement of a distortion of a signal received from the user equipment (103). The signal is associated with a power to be controlled. The base station (101) determines that the signal is unreliable if the distortion measurement is above a threshold or determining (308) that the signal is reliable if the distortion measurement is below the threshold. The base station (101) transmits a first UL TPC command to the user equipment (103) when the signal is determined to be unreliable or transmits a second TPC command to the user equipment (103) when the signal is determined to be reliable.

摘要： A method for uplink channel estimation comprises providing (210) of a channel state model in a channel estimator. An uplink radio signal of a present time slot is obtained (220) in the channel estimator as well as a series of transmit power control commands (230) issued for controlling a transmit power of the uplink radio signal. A delay between the time a transmit power control command is issued and the time that the transmit power control command is applied is estimated (232) based on measurements of the particular received uplink radio signal. Channel states are adapted (234) based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated (240) in the channel estimator, by tracking the demodulated uplink radio signal with the channel state model. A channel estimator performing such method is also described.
