摘要:
Disclosed herein are apparatus, methods and computer program products for transmitting signals in different frequency sub-bands used in a particular cell of a cellular wireless communications system in accordance with a power sequence and for selecting modulation schemes to be used in transmitting the signals in the different frequency sub-bands in dependence on signal transmission power allocated to the sub-bands in the power sequence. In the power sequence, signals to be transmitted in at least one sub-band are allocated a higher signal transmission power level than signals to be transmitted in other sub-bands used in the particular cell of the cellular wireless communication system. The differing signal transmission power levels allocated to the different sub-bands typically results in different SINR for signals transmitted at the higher signal transmission power levels and signal transmitted at the lower signal transmission power levels. In order to reduce the SINR difference between signals transmitted in the different sub-bands, modulation schemes are selected in dependence on the signal transmission power levels allocated to signals transmitted in the sub-bands.

A shared control channel structure includes at least one control channel to be allocated at least to a user for at least one of uplink and downlink directions in a network, which the at least one control channel is arranged as at least a part of a modular structure comprising of modular code blocks on at least two different sizes. One of such modular structures may be represented as a tree structure in particular, where each of the modular code blocks define one node of the tree, respectively.

The specification and drawings present a new method, system, apparatus and software product for implicit signaling and defining uplink allocations for an acknowledgment of downlink data using user downlink resource allocations, e.g., combined with user equipment detection of other user's allocations for data-non-associated signaling of hybrid automatic request process (HARQ) control information. Sequences of the downlink resource allocations are used to pre-define associated uplink control signaling resources.

An approach is provided for an efficient control signaling associated with an error control scheme. A determination is made whether data has been properly received according to an error control scheme. A first pilot sequence representing an acknowledgement is generated if the data is properly received. A second pilot sequence representing a negative acknowledgement is generated if the data is not properly received. A frame including either the first pilot sequence or the second pilot sequence is output.

In accordance with exemplary embodiments of the present invention a method, apparatuses and system are provided that may facilitate adaptiveness in channel quality reporting while limiting signaling overhead. The invention may include an adapter for setting the thresholds, boundaries or range of channel quality indices that are to be included in a report from a cell or user equipment terminal served by a network element, such as a Node B or an evolved Node B. The report provides an indication of the channel quality experienced by the cell or user equipment. The invention may also include determiner for selecting a number of channel quality indices to include in the report. The number of channel quality indices included may be based at least on the range selected by the network element, or may also be based on an observed scheduling history of the cell or user equipment terminal.

A method includes determining a value representative of an overall quality of a set of channels and transmitting during a reporting interval an indication of the determined value. The method also includes determining at least one additional value representative of a quality of a subset of the set of channels, and transmitting in at least one subsequent reporting interval an indication of the at least one additional value. Another method includes receiving during a reporting interval an indication of a value representative of an overall quality of a set of channels and receiving during at least one subsequent reporting interval an indication of at least one additional value representative of a quality of a subset of the set of channels. The method further includes, using the values, scheduling resources associated with the channels in the set, and transmitting an indication of the scheduled resources.

A wireless communication device adapted so that, in response to a repeat request indicating a communication signal, the device wirelessly retransmits the communication signal using a remapping of bits into at least partially different frequencies in the retransmission compared to the original transmission.
摘要:
The present invention is related to methods, apparatuses, systems and computer software for determining an amount of physical resources for downlink transmission, and allocating uplink physical resources for transmission of data-non-associated control signaling based at least on the amount of physical resources for downlink transmission. The amount of physical resources for downlink transmission comprises an amount of downlink control signaling. The present invention further relates to a framework for mapping the dedicated uplink control channels directly to single physical resource blocks. The framework is able to efficiently shift physical resources to and from the uplink control channel for ACK/NACK reports, in a data-non-associated control signaling scheme and on a per subframe basis. The present invention is also concerned with scheduler, for example an eNodeB scheduler, which uses its scheduling history and knowledge of user equipment capabilities to increase utilization of uplink resources.
