A method for data transmission is provided for determining movement speed and/or location of a mobile communication device; selecting, based on the movement speed and/or the location of the mobile communication device a frequency hopping mode from a plurality of frequency hopping modes to be used for data transmission to or from the mobile communication device; and transmitting the data using the selected frequency hopping mode.
摘要:
Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, precoding (e.g., Tomlinson-Harashima preceding) can be applied to “shape” the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.

Methods and apparatus that enable a wireless femtocell to operate in its designated frequency so as to minimize interference between the wireless femtocell and neighboring base stations (and other femtocells or nomadic cells). In one exemplary embodiment, the femtocell cell comprises a UMTS (Universal Mobile Telecommunications System) femtocell which has the ability to scan the air interface in a manner similar to that associated with a UE in order to identify unallocated resources within the wireless network, and subsequently request access for the unallocated resources. Business methods useful in combination with the aforementioned methods and apparatus are also disclosed.

According to an embodiment, a communication terminal is described comprising two radio communication modules and a controller configured to, in response to the reception of a request for starting communication using the second radio communication module, perform at least one of requesting from a communication device to perform reception quality measurements of signals received from the first radio communication module if the first radio communication module is transmitting signals to the communication device; and performing reception quality measurements of signals received from the communication device by the first radio communication module if the first radio communication module is receiving signals from the communication device.
摘要:
To register a communications device (UE1) in a communications network (CN), one or more temporary communications addresses (NI1, NI2) are negotiated between the communications device (UE1) and at least one registration unit (AV1) of the communications network (CN), the temporary communications addresses being valid only for a predeterminable utilization period (ZT1, ZT2). The temporary communications address (NI2) concerned is registered by the registration unit (AV1) for this utilization period (ZT2).
