摘要： Systems and methods for identifying Passive Intermodulation (PIM) products are disclosed. Some embodiments use RAN Performance Measurement (PM) counters, of actual DL Traffic Load to correlate with UL noise and interference counters. By using counters, the DL traffic is correlated to the increase in noise and interference in order to determine which DL carrier combinations are causing degradation to which UL carriers. In this way, aggressor-victim grouping can be identified through normal downlink traffic load with uplink interference to identify passive intermodulation products. This can be done for all aggressor-victim groups within a radio base station site or cluster of sites. Also, some embodiments enable estimating the maximum PIM interference created by the aggressor carriers. This helps operators to quantify the impact of PIM and can enable them to take counter measures. These embodiments are Radio Access Technology (RAT) agnostic and operator agnostic for the aggressors within a site.

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： In a method and a device for setting the Transport Format Combination size step in a scheduler of a cellular radio system to be used by a user equipment transmitting data to a radio base station of the cellular radio system, the Transport Format Combination size step is set as a function of a number of pre-defined cell and/or user conditions. This will increase the user bit rate at low load. Specifically, the time to reach a high bitrate in low load situations is reduced. This leads to enhanced user experience for bursty services such as World Wide Web (WWW) services.

摘要： A method for implementing power loop control at a RBS controlled by an RNC includes receiving an SIR target at the RBS which is determined by the RNC for a mobile station in communication with the RBS. In a first mode, one or more transmit power control commands are generated at the RBS for issuance to the mobile station based on the SIR target received from the RNC. In a second mode, one or more transmit power control commands are generated at the RBS for issuance to the mobile station based on an SIR target determined by the RBS for the mobile station instead of the SIR target received from the RNC. Also in the second mode, artificial mobile station connection quality information is reported from the RBS to the RNC so that the SIR target determined by the RNC is adjusted in accordance with the SIR target determined by the RBS.

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： In a cellular radio system the power control status of a mobile station is used in the base stations to generate power control commands. Hereby a radio base station can select a power control method that is optimal for the situation at hand. This is obtained by communicating power control status to base stations or deriving power control status in a radio base station. The radio base station is adapted to select power control method based on the power control status. Thus, a base station can select the most suitable power control improvement method, even during soft handover, thereby making make use of the advantages of different types of power control improvement methods.

摘要： It is presented a method for selecting an output stream for bits of a bit set. The method comprises the steps of: obtaining indicators of how much transmission power is allowed to be used; calculating a maximum number of bits that can be provided to each one of the two output streams; determining which one of the two output streams is to be a primary output stream and which one of the two output streams is to be the secondary output stream. The primary output stream is then filled first and any surplus is provided to the secondary output stream. A corresponding user equipment, computer program and computer program product are also presented.
