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： The present invention relates to methods, a communication network node and a user equipment for detecting collision of physical cell identities in a communication network system comprising radio base stations each serving at least one cell through which user equipments are moving. Reference signals comprising reference symbols corresponding to a physical cell identity are sent from said radio base stations to said user equipments over a radio interface. Transmission gaps of reference symbols are inserted in the reference signal in order to perform a physical cell identity collision test. The user equipments are arranged to detect if any other radio base station is sending reference symbols corresponding to the same physical cell identity during the transmission gaps. Thereby a physical cell identity collision is detected. The reference symbol transmission gaps are fractionally distributed within said reference signal such that at least some of said reference symbols are unaffected by said reference symbol transmission gaps.

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： Control of uplink transmit power for a first mobile station operating with scheduled uplink data transmissions. A change in uplink scheduled status for the first mobile station is detected (301). Filtering of uplink interference measurements for the first mobile station is adapted (302) to account for the detected change in uplink scheduled status for the first mobile station. Alternatively a change in uplink scheduled status for a second mobile station is detected and a current filtering state for filtering of uplink interference measurements for the first mobile station is adjusted by applying an estimated expected change in interference associated with the detected change. A signal quality for uplink transmissions from the first mobile station is determined (303) based on measurements of received signal strength from the mobile station and the filtered uplink interference measurements. An uplink transmit power command is generated (304) for the first mobile station based on a comparison of the estimated signal quality to a signal quality target.

摘要： A received signal of interest is processed by determining timing of interference spikes in the received signal of interest. Receivers can determine when certain types of interference spikes are expected to occur, e.g., based on when different users are scheduled to transmit data during an overlapping portion of the same transmission time interval. The interference timing information is used by the receiver to soft scale signal values recovered from the received signal of interest that coincide with the interference spikes separately from remaining ones of the signal values. This way, fast changing interference power can be accurately tracked during periods of known interference spikes while also accurately tracking slower changing interference power during other periods.

摘要： The present invention relates to handover procedures in a cellular communications system (1). The cells (10-70) of the system (1) are divided into multiple handover-related classes based on their respective radio coverage characteristics. Each such cell class is then associated with a unique handover parameter or a unique set of parameters that are used in handover procedures involving the cells (10-70). The parameter values are adapted for the radio coverage characteristics of each cell class in order to generate a suitable handover region size of the cells (10-70). The handover parameters are used together with user equipment-assisted signal quality measurements for triggering the handover procedures.
