Abstract: A system and method of instant messaging is disclosed and includes transmitting an indication from a wireless device to an instant messaging server that instant messaging is enabled at the wireless device. Further, a plurality of communication signals between the wireless device and a plurality of base stations are monitored. After determining that the wireless device has one remaining communication signal with one base station, the one remaining communication signal is monitored. Moreover, a time history of signal strength data for the one remaining communication signal is recorded and a slope of the signal strength data is determined. Based on the slope of the signal strength data, it can be determined whether an imminent loss of signal is about to occur at the wireless device.

Abstract: Pilot and data transmission schemes for multi-antenna communication systems utilizing multi-carrier modulation are provided. Subband multiplexing is used to avoid interference resulting from transmitting multiple signals simultaneously from multiple antennas. M usable subbands are initially arranged to form multiple groups of subbands, with each group including a different subset of the usable subbands. Each of T transmit antennas is then assigned one or possibly more subband groups for pilot transmission and typically one subband group for data transmission. Pilot and data may then be transmitted from each antenna on the subbands assigned to that antenna for pilot and data transmission. For each transmit antenna, the transmit power for each assigned subband may be scaled higher such that all of the total transmit power available for the antenna is used for transmission. Pilot and/or data may be transmitted simultaneously from all T antennas on all usable subbands without causing mutual interference.

Abstract: Aspects describe service discovery of wireless MDDI client-capable devices though interaction with an underlying bearer protocol. Service discovery can be performed when the underlying layer supports multicasting, when the underlying layer is wiMedia UWB MAC and/or UDP/IP.
