    摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.

    摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

    摘要： A method and apparatus for use in a wireless communication system to detect frequency division duplex (FDD) or time division duplex (TDD) after the radio timing and cell group ID have been determined from the S-SyS during a cell search, by correlating reference symbols (RSs) and detecting whether the RSs are on resource elements corresponding to FDD or TDD. By correlating the known RS, which is known after the cell ID is detected, to the assumed RS positions for FDD or TDD, the duplex form is detected.

    摘要： A method for automatic repeat request operation of a plurality of simultaneous automatic repeat request processes is disclosed. The method comprises receiving a transmission comprising at least one transport block; storing soft bits of the transport block in a buffer; and transmitting an automatic repeat request process signal, wherein the transmitting of the automatic repeat request process signal comprises one of: transmitting an acknowledgment signal if the transport block is determined to be properly received, transmitting a negative acknowledgement signal if the transport block is determined to contain an error, and transmitting a blocking indication signal if there is not room enough for the soft bits in the buffer. A transceiver arrangement and a computer program are also disclosed.

    摘要： The present invention relates to methods and apparatus for providing a more flexible configuration of sounding reference signal, SRS, transmission. This is achieved by dynamically triggering a mobile terminal to transmit SRS. Thus, embodiments of the invention include a method implemented by a base station in a communications network that semi-statically configures some uplink symbols for periodic SRS transmission and other uplink symbols for aperiodic SRS transmission. The method includes dynamically determining whether an uplink symbol that has been semi-statically configured for aperiodic SRS transmission is to be used by a given mobile terminal at a given time for SRS transmission. The method then further includes signaling a terminal-specific instruction that indicates said determination to the given mobile terminal.
