摘要： A power control applied to a radio network controller (40) when a user equipment (300) is in communication with a serving radio base station (10) and at least one other radio base station (20) involves the radio network controller (40) providing a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The radio network controller (40) generates an updated power quality target for a reference control channel based on the quality representation and transmits the updated power quality target to at least one of the serving radio base station (10) and the at least one other radio base station (20). Alternatively, the radio network controller (40) generates an updated power offset for the uplink control channel (12) relative a reference control channel based on the quality representation and transmits the updated power offset to the user equipment (300).

摘要： Method and controlling network node (140) for transmitting data to a user equipment (130) over a set of radio links (115,125), when a radio link (115,125) is added, or removed. The controlling network node (140) is configured to communicate data to the respective radio network node (110,120) over a respective backhaul link (118,128), of which at least one backhaul link (118) is connected over an Internet Protocol, IP, network (150). The method (500) comprises measuring (501) the time delay over the corresponding backhaul link (118,128) for each radio link (115,125), determining (502) time difference between them, calculating (503) a buffer time for each radio link (115,125), and buffering (507) data in a buffer (625) for the calculated period of time before forwarding the data to the radio network node (110,120), for transmission to the user equipment (130).

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： Random access coverage is assured while at the same time supporting high uplink data rates in a same service area served by a base station. A set of radio resources are shared by multiple mobile terminals for transmitting uplink to the base station including requests for access to service from the base station and transmissions for active connections with the base station. A first repeating time period and a second different repeating time period are defined. Uplink transmission grants are scheduled for active connections that permit use of a greater amount of the radio resources during the first repeating time period. Uplink transmission grants are also scheduled for active connections that permit use of a smaller amount of those resources during the second repeating time period. At least some random access requests to the base station are controlled to occur only during the second repeating time period.

摘要： A radio base station and a method therein for scheduling an uplink radio resource to a first user equipment in a wireless communication system which employs CDMA are provided. The method includes measuring an Interference Suppression (IS) gain for each user equipment in a set of user equipments currently being served by the radio base station. The method further includes determining a user constellation pertaining to information regarding the different user equipments in the set of user equipments and their respective bitrates, and updating a table of IS gains with the measured IS gain in bins corresponding to the determined user constellation. The method further includes predicting a load based on at least the updated table, and scheduling the uplink radio resource to the first user equipment at least partly based on the predicted load.
