Abstract: Determination of the location and bearing of an asset having an RF-tag imbedded therein is accomplished through extended radio frequency triangulation. A beacon arrangement determines the direction of an RF tag from a specially designed beacon node. RF-tag localization is further improved by repeating this measurement from multiple spatially displaced beacon nodes.

From the phase shifts and the known arrangements of the antennas the angle at which the RF-tag is RF visible from the specific beacon node can be estimated. Determination of the signal phase shifts are part of the baseband processing hardware, the rest of the location determination procedure may be realized in software.

Abstract: The basic idea of the present invention is to not only design a frequency-selective precoder with respect to the channel properties but also to ensure that the time-domain spread is limited. Hence the energy of the time-domain impulse response of the frequency-selective precoder is concentrated. According to a first embodiment, the time-domain spread is limited by designing a precoder such that it allows smooth transitions in the frequency domain between the values of the precoder when the precoder provides a staircase function. The smooth transitions can either be achieved by lowpass filtering the frequency-domain representation, the staircase function, of the precoder or by designing the precoder such that the sharp jumps are replaced by slopes. According to a second embodiment, the time-domain spread is controlled. The control may be achieved by employing a time-domain parameterization to precisely control the introduced additional time-domain spread.

Abstract: Downlink (DL) subframes and DL hybrid automatic repeat request (HARQ) messages may be protected by time division multiplexing (TDM) partitioning. However, TDM partitioning may not be required for uplink (UL) subframes in general. For example, information carried over a physical uplink control channel (PUCCH), may be protected by frequency division multiplexing (FDM) partitioning. In fact, one UL subframe may correspond to eNBs of multiple power classes. Since TDM partitioning may be required for DL transmissions, one DL sub frame may not correspond to the eNBs of multiple power classes. For some embodiments, groups of subframes may be allocated to the different power classes. Therefore, subframes allocated to an eNB of a power class may observe reduced or no interference from eNBs of other power classes.

A transmitter 13 transmits data through the radio channel CH2 for broadcast communication in accordance with the adjusted timing TA of transmission.

Abstract: Systems and methodologies are described that facilitate efficient power control command management in a wireless communication environment.
