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.

摘要： A hierarchical link scheduling system and method is provided. A central controller gathers network information, including global parameters and long term demands, and determines an initial schedule for link activation based on these variables. A scheduler receives the initial schedule and modifies the initial schedule based on local parameters, inter-schedule negotiation, or other short term or localized requests. The scheduler activates the links according to the modified schedule. Accordingly, the scheduler can be responsible for modifying the initial schedule provided by central controller with localized or short term requests or demands, and providing the necessary parameters to enable link activation between nodes according to the modified schedule.

摘要： Embodiments of the present disclosure are directed towards a communications system and uplink transmission method which may dynamically adapt to changing conditions of the backhaul network. A traffic engineering element (TEE) is disclosed which receives a request from at least one wireless device for uplink data transmission. The TEE then determines the backhaul conditions of the backhaul network and coordinates uplink data transmissions from at least one wireless device to one or more receivers dependent on the determined backhaul conditions.

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.
