    摘要: In one embodiment, the method of configuring a common search space (CSS) for at least one user equipment (UE) in a wireless communication system with at least a first type of physical downlink control channel includes broadcasting at least one parameter of a common search space (CSS), none of the parameters being the number of orthogonal frequency-division multiplex (OFDM) symbols. In one embodiment, a method of configuring a default user equipment-specific search space (USS) for a user equipment (UE) in a wireless communication system with at least a first type of physical downlink control channel includes broadcasting at least one parameter of the default USS, none of the parameters being based on an identifier of the UE. The broadcasting may occur before UE-specific signaling. In one embodiment, a method of configuring or reconfiguring the USS may include transmitting at least one parameter of the USS with UE-specific signaling.

    摘要: One embodiment of the method includes defining, at the user equipment, a range for the maximum output power. The range includes a maximum value and a minimum value. The minimum value is based on a maximum power signalled by a base station, a power class of the user equipment, a maximum power reduction permitted, an additional maximum power reduction permitted, a reduction term dependent on transmission bandwidth, and a power management term. The method further includes setting, at the user equipment, the maximum output power within the defined range.

    摘要: The present invention provides a method for mitigating outages in wireless communication systems using feedback for control channels formed by aggregating groups of resource blocks or resource elements, the method. One embodiment of the method includes generating control channel feedback at user equipment. The control channel feedback is generated using one or more measurements performed on signals received at the user equipment over a downlink control channel at a current aggregation level. The method also includes transmitting the control channel feedback over an uplink channel and using this information for the optimal implementation of Cell range expansion by the network.

    摘要: The present invention provides a method for uplink control channel allocation for a relay backhaul link. Embodiments of the method include allocating resource blocks in a subframe for a backhaul downlink control channel between an access node and a relay station. The resource blocks are allocated from a first portion of the subframe that is different than a second portion of the subframe allocated to a downlink control channel between the relay station and at least one access terminal. Embodiments of the method also include transmitting control information from the access node in the resource blocks.

    摘要: A method of configuring user equipment in a wireless communication network to operate to receive a dynamically changing coordinated multipoint transmission from one or more transmission point in said network, a computer program product and network control node operable to perform that method. The method comprises: determining, for the user equipment, a set of two or more transmission points from which the user equipment may receive a transmission and allocating them to a coordinated multipoint transmission measurement set associated with the user equipment; allocating a set of modes of operation of the transmission points in the coordinated multipoint transmission measurement set for communication with the user equipment; associating a codepoint to each mode in the allocated set of modes of operation of the set of transmission points to form a codebook; and informing the user equipment of the codebook. Aspects and embodiments described recognise that without significantly increasing the number of bits required in a downlink control information message, dynamic switching among some preselected or preconfigured coordinated multipoint transmission schemes can be efficiently supported within a network. The configuration of code points interpreted by user equipment may be set on a user equipment by user equipment basis and can be preconfigured by RRC signalling semi-statically.
