    摘要: The signals from adjacent transmitters reinforce one another. As a result of this over-the-air combining, signal quality is improved in the network and especially at or near cell boundaries. The present invention provides a graduated single frequency network (GSFN) wherein transmitters in cells throughout a geographic area cooperate to broadcast data to user terminals throughout the geographic area, and adjacent transmitters transmit signals that substantially reinforce one another. When transmitting the data, transmitters in certain adjacent cells throughout the geographic area may employ slightly different transmit parameters to provide slightly different transmission signals. The transmission signals used to transmit the data may be varied in a graduated fashion throughout the geographic area, wherein even when there is a difference in the transmission signals of transmitters in adjacent cells, the transmission signals reinforce one another despite being different.

    摘要: The present invention is a method and system for supporting a beamforming antenna system in a multiple user mobile broadband communication network including a process for setting and adjusting the magnitude and phase of the signal to user equipment from each antenna. Namely, the present invention supports the communication of power signal values or levels to user equipment in a manner that keeps pace with the rapid variations of the power levels that occur in the dynamic scheduling of transmissions on the cell site. The present invention satisfies this need for an improved signal strength signaling to user equipment for the situation where multiple users are located on the cell site.

A first type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion of a transmission resource, transmitting broadcast traffic on at least one first antenna of a plurality of antennas in the first traffic portion using a first sub-channelization, transmitting multicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, in the first traffic portion using a second sub-channelization, and transmitting unicast traffic on at least one antenna of the plurality of antennas in the second traffic portion using a third sub-channelization. A second type of sub-channel arrangement involves defining a first traffic portion and a second traffic portion, wherein for a portion of the transmission resource, a portion of the first traffic portion overlaps with a portion of the second traffic portion. In the portion of the transmission resource in which a portion of the first traffic portion overlaps with a portion of the second traffic portion, the channel arrangement involves transmitting broadcast/multicast traffic on at least one first antenna of a plurality of antennas using a first sub-channelization and b) transmitting unicast traffic on at least one second antenna of the plurality of antennas, the at least one second antenna being distinct from the at least one first antenna, using a second sub-channelization. The first, second and third sub-channelizations may be based on either one of or a combination of FDM sub-channelization and TDM sub-channelization.

    摘要: Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.
