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 method in a first radio network controller, RNC, (105, 405) for handling a reuse of a scrambling code in a cellular network (100) is provided. The first RNC (105, 405) defines a set of scrambling codes. Each scrambling code in the defined set is locally reused by at least two cells in the cellular network (100). The first RNC (105, 405) receives a measurement report from a user equipment (180). The measurement report is related to a scrambling code that is comprised in the defined set of scrambling codes. The first RNC (105, 405) determines that the reported scrambling code is comprised in the defined set of scrambling codes. The first RNC (105, 405) initiates, based on the determination, a process for identifying, among the at least two cells in which the reported scrambling code is locally reused, an originating cell from which the reported scrambling code originates.

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： Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal.

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.

摘要： A method for power control stabilization in the uplink of a cellular CDMA communication system applying a fast inner loop power control comprises determining (210) of a radio frame based RoT value for a cell. A radio frame based SINR is determined (212) for individual UEs in the cell. The RoT value is compared (214) with a first threshold. Each frame based SINRs is compared (218) with a second threshold. The fast inner loop power control for a UE is broken (220) in dependence of the comparisons. The breaking comprises commanding (222) of a first number of consecutive power down commands to UEs having the frame based SINR above the second threshold for a RoT value above the first threshold and toggling (224) of power control commands for the subset of UEs during a second number of radio frames for a RoT value above the first threshold.
