摘要： In MU-MIMO scenarios, a target mobile terminal can be exposed to data streams intended for other mobile terminals. If the target mobile terminal is capable of interference cancellation, then a serving base station can provide the target mobile terminal with interference information so that the target mobile terminal can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal or are allocated for common listening. The serving base station exchanges configuration information with neighboring base stations over inter-BS links. The inter-BS links use resources that are different from the radio resources used between the base stations and the mobile terminals.

摘要： A base station includes an emulation controller (20) configured to receive signals indicating that another base station in an active mode managing a cell, having a predetermined cell identity and coverage area, will go into an idle mode and no longer manage the cell, and to determine terminal activity in the cell. A baseband processing unit (18) is connected to the emulation controller (20) and configured to emulate the active mode of the other base station by taking over management of the cell, in at least part of its coverage area, using the same cell identity.

摘要： Error protection based on a nonlinear code set may be used in a multiple input multiple output (MIMO) radio communications system. A decoder decodes received MIMO data streams and generates an automatic repeat request (ARQ) message for data units received for the MIMO data streams for each transmission time interval. An encoder codes the ARQ message using a code word from a nonlinear code set. At the data transmitter, which transmits one or more data units in transmission time intervals from two or more MIMO data streams, the ARQ message associated with the transmitted data units is decoded using a code word from the nonlinear code set.

摘要： A base station transmits signals on a frequency (f1) in an active transmission interval (TI) having a starting time and being part of a transmission cycle (TC) including other active transmission intervals for other frequencies (f0, f1, f2, f3) appearing in a predetermined discontinuous transmission scheme that specifies the relationship (Δ1, A2, A3) between the starting times of the active transmission intervals of the frequencies of the set. The mobile station scans the set of frequencies during a scanning cycle (SC) corresponding to the transmission cycle (TC) and determines the frequencies at which the base stations transmit. The start of each scanning is made at a point in time that is specified for the corresponding frequency by the discontinuous transmission scheme and the scanning of one frequency involves ending scanning of this frequency at the end of a time range (TR) of pre-determined length if no signal is detected within this time range.

摘要： An extended cell search procedure enables more inclusive measurement reports by mobile terminals operating in a heterogeneous network. The mobile terminal may be configured to conduct an extended cell search to enable better detection of signals transmitted from weaker cells. For mobile terminal with extended cell search capabilities, the network sends an extended cell search message to the mobile terminal when there is a need for an extended cell search. In response to the extended cell search message, the mobile terminal uses an extended cell search procedure rather than the normal cell search procedure (as specified in Rel-8 of the LTE standard) when performing cell searches.

摘要： Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.
