    Abstract: A method for reducing overhead when transmitting an Internet Protocol (IP) packet begins by selecting a watermarking signature based on the IP address of the packet. The watermarking signature is applied to the packet and the IP address is removed from the packet. The packet is sent to a receiver, which looks up the IP address of the packet by using the watermarking signature. The watermarking signature can be a radio frequency watermarking signature or a digital watermarking signature. A similar method employing watermarking can be used to reduce medium access control header overhead.

    Abstract: A connection between a wireless transmit/receive unit (WTRU) and another node through a wireless network is established. The connection is used for communication. A user input is received. In response to the received user input, a communication through the connection is recoded while the WTRU still communicates the communication to a user of the WTRU. The recorded communication is retrieved and the recorded communication is communicated to the user at a later time.

    Abstract: A wireless network provides controlled wireless communications with multi-mode wireless WTRUs (33, 37). The wireless network has at least one base station (25) having a transceiver operating in an infrastructure communication mode withmulti mode WTRUs and a controller that transmits control signals via infrastructure communications with a WTRU that control peer-to-peer mode communications (40) of that WTRU with other WTRUs. A WTRU has transceiver components configured for selective operation in an infrastructure communication mode with a network base station and in a peer-to-peer communication mode with other WTRUs. The WTRU also has a transceiver controller configured to selectively control peer-to-peer mode communications with other WTRUs based on communication signals received in infrastructure communications with a network base station. Preferably, the transceiver controller is configured to control the transceiver components to switch between infrastructure communication mode and peer-to-peer communication mode based on(duality of Service criteria).

    Abstract: The present invention relates to hierarchical modulation (HM) and demodulation for global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) evolution. In one embodiment, HM symbols are generated by generating primary modulated symbols based on a first bit group, generating secondary modulated symbols based on a second bit group, and combining the primary modulated symbols and the secondary modulated symbols. In another embodiment, the HM symbols are demodulated. In yet another embodiment, a received GERAN signal is converted to baseband complex symbol values, which are processed to produce training symbols and data symbols that carry pilot symbols. Channel parameters of the radio channel are estimated based on the training symbols. An equalized signal is generated based on the estimated channel parameters and data symbol. Primary and secondary demodulated symbols are generated based on the equalized signal.
