摘要： Techniques are described for adapting receiver settings used by a mobile terminal operating in a heterogeneous network comprising macro cells and pico cells with overlapping coverage areas. A first set of subframes is allocated to the pico cells for downlink transmissions to a mobile terminal in a link imbalance zone. The mobile terminal acquires information about the subframe allocation and uses the subframe allocation information to select the signals used for adapting receiver settings used when operating in the link imbalance zone.

摘要： The present invention relates to a method and apparatus for multi-stream wireless communication between a transmitter node and a receiver node. The method comprises applying an open-loop multi-stream transmission technique during an initial part of a transmission burst. In another step of the method, detailed channel state information is received (54). The detailed channel state information indicates transmission pre-coding to be used during the transmission burst when applying a closed-loop multi-stream transmission technique. The method further includes switching (55) from the open-loop multi-stream transmission technique to the closed-loop multi-stream transmission technique during the transmission burst, in response to receiving the detailed channel state information. The method is applicable to both uplink and downlink transmission bursts.

摘要： More than one set of sounding signal configuration parameters are determined for the same mobile terminal. The mobile terminal uses the sets of configuration parameters to generate different sounding reference signals which can be used for different purposes such as estimating timing and channel quality. In one embodiment, a method of configuring uplink sounding transmissions by mobile terminals in a wireless communication network is characterized by determining different sets of configuration parameters for sounding signal transmissions for a given mobile terminal (200). The different sets of configuration parameters are transmitted to the mobile terminal, allowing the mobile terminal to generate different sounding signals for different uses by the wireless communication network (202).

摘要： A method of controlling access in a telecommunication network in which a communication medium, such as a set of frequencies, time slots, or codes, is shared among a plurality of mobile units. Transmissions from the mobile units utilize different access modes, such as a direct access mode and a scheduled access mode. Additionally, the transmissions are divided into different communication types, each having an associated priority. A mode access control unit determines for each priority, which access mode to utilize for the associated communication type. Mobile units having data to transmit access the shared communication medium utilizing the access mode determined for the priority of the communication type to which the data belongs.

摘要： A communication device has a first transceiver that operates in a first communication system in the presence of a second transceiver that operates in a second communication system that is unrelated to the first communication system. A scheduler of packets for transmission by the first transceiver uses information about when the second communication system will be transmitting a signal that will interfere with reception by the first transceiver, and schedules data for which re-transmission is not essential in those time slots in which an implicit NACK is expected due to the second transceiver's operation.

摘要： Control channel information is formulated for transmission in orthogonal frequency division multiplexing (OFDM) systems. In an example embodiment, a method entails formulating control channel information for a transmitting device operating in an OFDM system in which a control channel spans n OFDM symbols, with n being an integer. The method includes acts of allocating, creating, and mapping. Control channel data is allocated to at least one set of resource element groups. At least one order for the set of resource element groups is created in accordance with one or more permutation mechanisms that involve at least one interleaving sequence having a low cross-correlation property. The set of resource element groups is mapped to resource elements of the n OFDM symbols of the control channel responsive to the order that is created using the permutation mechanism(s). The permutation mechanisms may include interleaving sequence(s) and/or cyclic shift(s).
