Abstract:
A method and transmitter for generating a multicarrier signal, to be transmitted to a receiver, are provided. The method comprises dividing symbols to be transmitted into protected symbols and non-protected symbols; precoding non-protected symbols in a first precoder; precoding protected symbols in a second precoder; creating a modified non-protected symbol vector, based on the precoded non-protected symbols and the precoded protected symbols; and modulating the modified non-protected symbol vector and the protected symbols, thereby generating the multicarrier signal. Also, a method and receiver are disclosed.
Abstract:
A method in a radio resource allocator of a radio access network is disclosed. The network comprises at least one first layer and at least one second layer, the first layer is higher than the second layer; and the method in a first radio resource allocator of the first layer comprises: decides if a second radio resource allocator of the second layer in an autonomous mode or in a controlled mode for at least one portion of available radio resources; when the second radio resource allocator in the autonomous mode, allocates the at least one portion of available radio resources to the second radio resource allocator; when the second radio resource allocator in the controlled mode, allocates the at least one portion of available resources to radio resource users of the radio resource users of the second radio resource allocator and/or radio resource allocators of a third lower layer.

Abstract:
The present invention relates to a Method for scheduling and/or muting radio resources in a wireless communication system, said wireless communication system comprising a plurality of network nodes and a plurality of user nodes; the method comprising the steps of: measuring, by at least one user node, received signal strength of radio signals transmitted from one or more network nodes so as to obtain received signal quality and/or interference associated with said one or more network nodes; arranging, by said user node, the received signal quality and/or interference associated with said one or more network nodes in an order or a ranking with respect to at least one radio signal criterion; signalling, by said user node, said order or ranking to at least one network node; and scheduling and/or muting radio resources based on said signalled order or ranking.

Abstract:
A method is provided for transmitting constellation symbols in a communication system. A set of orthogonal time-frequency mapping patterns (TFPs) is generated from a TFP. And a TFP from the set of orthogonal TFPs is selected for transmitting a block of constellation symbols.
Abstract:
A method of allocating communication resources for a communication between a transmitter and a receiver in a communication system, the communication resources being divided in time periods and frequency sub-bands. The transmitter receives a channel quality measurement sent by the receiver. The transmitter performs allocation of a first part of the communication resources to the receiver according to the channel quality measurement if allocation of the first part is selected, or allocation of a second part of the communication resources to the receiver if allocation of the first part is not selected. The transmitter informs the receiver of allocated communication resources, and the allocated communication resources being designated for frequency localized channels or for frequency distributed channels.
