There is provided fine-grain and backward-compliant resource allocation, comprising allocating, to a control channel, one of a first plurality of bandwidths being standardized for a first radio access standard, and allocating, to a data channel, one of a second plurality of bandwidths being standardized for a second radio access standard, the second bandwidths plurality exceeding the first bandwidths plurality in terms of at least one of granularity and range. The thus disclosed resource allocation may exemplarily be applied on a downlink.

Fine-grain and backward-compliant resource allocation

A method and apparatus for controlling retransmissions in multipoint reception is disclosed. In the method it is determined that additional information is needed for decoding of at least one received information block. A procedure is selected for obtaining the additional information from a plurality of options to proceed based on information about predicted result of at least one of the options. In accordance with an aspect an indication of one of a positive acknowledgement of the information block, a negative acknowledgement of the information block and suspension of retransmission of the information block is generated and communicated on a retransmission control channel.

Controlling retransmissions

It is disclosed a method comprising accommodating, in frequency domain, a first bandwidth of a first carrier signal with respect to a second bandwidth of a second carrier signal such that the first bandwidth adjoins to or overlaps the second bandwidth, the first bandwidth being greater than the second bandwidth.

Transmission and reception of a wideband signal with narrowband interference

There is provided a method for configuring a communication channel between a base station and a user equipment within a cellular network system. The cellular network system includes at least one cooperation area. The base station is assigned to the at least one cooperation area, and the user equipment is served by the base station. The method includes applying, by the base station, a vertical sectorization and thereby creating the at least one cooperation area, determining, by the base station, the location of the user equipment in relation to the at least one cooperation area, and configuring, by the base station, the communication channel between the base station and the user equipment by using coordinated multipoint processing, if the determined location of the user equipment corresponds to a predetermined location.

Method and apparatuses for configuring a communication channel

There is provided fine-grain and backward-compliant resource allocation, including allocating, to a control channel, one of a first plurality of bandwidths being standardized for a first radio access standard, and allocating, to a data channel, one of a second plurality of bandwidths being standardized for a second radio access standard, the second bandwidths plurality exceeding the first bandwidths plurality in terms of at least one of granularity and range. The thus disclosed resource allocation may exemplarily be applied on a downlink.

It is disclosed a method including accommodating, in frequency domain, a first bandwidth of a first carrier signal with respect to a second bandwidth of a second carrier signal such that the first bandwidth adjoins to or overlaps the second bandwidth, the first bandwidth being greater than the second bandwidth. In a further aspect, prior to the transmission, the interference of the modulated second carrier signal is subtracted from each of the plurality of subcarrier signals of the first carrier signal.

An apparatus is provided, including an observing function configured to observe an indication about the coverage status of a user equipment; a deciding function configured to decide, based on the indication, to switch into a coverage extension mode; a providing function configured to provide a scaling number in dependence of the coverage extension mode; an allocating function configured to allocate, for data to be transmitted to a user equipment, a first modulation and coding scheme, a first modulation order, a first size of a transport block, and a first number of resource blocks per transport block according to an orthogonal frequency division multiplexing technology, a reducing function configured to reduce a first size per resource block, being the quotient of the first size of the transport block and the first number of resource blocks per transport block, based on the scaling number, thus obtaining a second size per resource block, being the quotient of a second size of the transport block and a second number of resource blocks per transport block; and a scheduling function configured to schedule, for the data, the second size of the transport block and the second number of resource blocks per transport block.

Enhanced physical downlink shared channel coverage

It is provided an apparatus, including observing means configured to observe a first parameter; deciding means configured to decide, based on the first parameter, whether or not an original search space of a downlink control channel of an orthogonal frequency division multiplex technology is to be redefined; and redefining means configured to redefine the original search space, thus obtaining a redefined search space.

Extension of physical downlink control channel coverage

A larger second bandwidth is fitted to a first transmission bandwidth by blanking PRBs at one or both edges of the larger second bandwidth. A first set of control channels is mapped to unblanked PRBs of the second bandwidth using a restricted set of physical cell identities that map only to the unblanked PRBs. A second control channel is punctured so that after it is interleaved and cyclically shifted the punctured CCEs fall on the blanked PRBs, and this second control channel is power compensated for the punctured CCEs. The first set and the second control channels are assigned in view of the puncturing and blanked PRBs, an IFFT for the larger second bandwidth is performed on a signal using zeros at the blanked PRBs, the signal is filtered to the first bandwidth and transmitted over a bandwidth not to exceed the first bandwidth.
