摘要： A method (100) in a network node serving a User Equipment (UE) capable of network assisted interference cancellation is disclosed. The method involves a signaling (104) of an indication to the UE indicating whether the UE should enable or disable (108) the network assisted interference cancellation, or whether the UE should autonomously choose (110) to enable or disable the network assisted interference cancellation. The enabling or disabling is done for at least one of demodulating the downlink channel or computing the channel state information. The method further involves a receiving (106) of information from the UE about whether the network assisted interference cancellation has been used by the UE for at least one of demodulating the downlink channel and computing the channel state information. A related method in a UE is also disclosed, together with the network node and the UE as such.

摘要： A method, User Equipment, UE, (700), and first base station (800) serving a first cell (140) for performing an access request by the UE tor operatively connecting the UE to a second cell (110). The UE (700) obtains radio quality parameters indicating quality of radio reception between the UE and the first and second cells. Based on the obtained radio quality parameters, it is determined whether the UE is in a link imbalance zone (148) where the UE has an option to be connected to both the first cell (140) and the second cell (110). If so, the UE sends access request information, to the first base station (800) and indicates availability of the UE to be redirected to the second cell. The first base station (800) may redirect the UE to the second cell (110) when a load of the first cell ( 140) meets pre-defined load criteria.

摘要： In one embodiment, a method in a network node is provided. The network node is configured to use a first power level for transmitting data in subframes of a first type, and to use a second power level for transmitting data in subframes of a second type. The method comprises signaling (520) first and second information to a network entity. From the first information, a power offset for subframes of the first type is derivable. The first power offset represents a relation between a power level for transmitting reference signals and the first power level. From the second information, a power offset for subframes of the second type is derivable. The second power offset represents a relation between the power level for transmitting reference signals, and the second power level.

摘要： Example embodiments presented herein are directed towards a base station (401), and corresponding method, for scheduling a downlink broadcast transmission using PDSCH. The base station (401) is also configured to provide an OFDM PDSCH to a wireless terminal (505A) which monitors ePDCCH for receiving downlink control data. Thus, by applying such a symbol, a wireless terminal (505A) which monitors ePDCCH and a wireless terminal (505B) which monitors PDCCH may receive the same downlink broadcast transmission on PDSCH. Example embodiments are also directed towards a wireless terminal (606A) for receiving such downlink broadcast transmissions.

摘要： Inter-cell interference coordination across layers of a communication network can be implemented by configuring a cell to transmit one or more downlink transmission resources having variably reduced transmission activity. A transmitting node, such as a macro cell, can transmit transmission resources, such as resource elements, resource blocks, subframes, and frames, having reduced transmission activity at varying predictable times according to a selected cell activity pattern. A receiving node, such as a user equipment, can decide to make received signal measurements according to the cell activity pattern.

摘要： Transmitter(s) (34), radio base station nodes (38) comprising transmitter(s), and methods of operating transmitter(s)/radio base station(s) involve handling discontinuous transmission indication bits, particularly when transmitting using a 16 QAM signal point constellation having an I-branch and a Q-branch (for a quadruple of bits comprising two I-branch bits, i1 and i2, and two Q-branch bits q1 and q2). The transmitter(s) (34) and the radio base station nodes (28) comprised thereof are operated to perform a Multimedia Broadcast Multicast Service over Single Frequency Network (MBSFN) transmission wherein the MBSFN transmission comprises mapping data to a Secondary Common Control Physical Channel (S-CCPCH). For the Secondary Common Control Physical Channel (S-CCPCH) the methods include operating a 16 Quadrature Amplitude Modulation (QAM) transmitter (34) according to a predetermined strategy. The predetermined strategy is configured whereby one or more discontinuous transmission indication bits input to the transmitter (34) result in unambiguous determination of output values from an Inphase (I) output and a Quadrature (Q) output.
