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 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.

A wireless communication device, method and system adapted so that, in response to a repeat request indicating a communication signal (because of an error in transmission of the communication signal), the communication signal is wirelessly retransmitted using a remapping of bits into at least partially different frequencies in the retransmission compared to the original transmission.
摘要:
A method, computer program product and electronic device are provided. The method includes the steps of: prioritizing data for each link into higher priority data and lower priority data for that link; and selectively transmitting a first signal on a first sub-band and a second signal on a second sub-band. The first sub-band is characterized as having better signal transmission characteristics than the second sub-band. The first signal comprises data from the higher priority data and the second signal comprises data from the lower priority data.

The specification and drawings present a new method, system, apparatus and software product for determining (e.g., calculating) a load measure by a network element (e.g., Node B or any other network element) for optimizing information traffic in communication networks (e.g., wireless communication systems). This load measure may represent the amount of available/excess traffic that a given network element may carry and is a relative measure, which would take into account the total amount of resources available in the system and the amount of resources that are free for carrying only “important” or “essential” traffic, using a weighed method described herein.

In a non-limiting aspect thereof, the exemplary embodiments of this invention provide a method including sending to a user equipment information including channel quality indicator (CQI) related parameters for dynamically controlling CQI reporting of the user equipment, where the CQI related parameters are specified for the user equipment in response to information input to a network node and where the specified CQI related parameters include a reporting accuracy mode adapted for an available signaling capacity, and receiving CQI reporting from the user equipment in accordance with the CQI related parameters.
摘要:
A method is provided for applying frequency domain multiplexing of unicast and multicast services on a single carrier, such that both services can operate at the same time, and may be received with the same RF front end and A/D converter. In order to reduce subcarrier interference between unicast and multicast tones a guardband is introduced between the unicast and multicast bands, where the guardband can be fixed or variable within a sub-frame. Also disclosed is a device and computer program product operable with the device.
摘要:
A method is described for transmitting data, particularly but not exclusively packet data, from a transmitting station to a receiving station via a wireless channel. The data is transmitted in transmission intervals or TTI slots. The method comprises estimating a utilisation factor representing usage of the transmission intervals, and scheduling the data for transmission to increase the utilisation factor. The effect is to reduce stochastic pattern interference for other users in a wireless communications network. A network node for implementing the above method is also disclosed.
摘要:
The present invention relates to a method and system for scheduling data packets in a base station device of an access network. An information indicating a retransmission status of a data packet is provided to the base station device, and a scheduling priority is allocated to the data packet based on the retransmission status information. Thereby, retransmission packets can be scheduled earlier and round trip times can be reduced, so as to decrease the risk of timeouts and stalling and to loosen buffer requirements.
