    摘要: A method of providing delay information in a multi-antenna transmission system is provided. A time delay value is selected from a set of time delay values. A mobile station is informed of information related to the selected time delay value. The same data is transmitted from a first antenna and from a second antenna. The data is transmitted from the second antenna after the data is transmitted from the first antenna according to the selected time delay value. The time delay value is selected based on a deterministic method or a random method.

    摘要: A method of configuring a sub-slot having a layer-modulated multi-user packet (MUP) is disclosed. More specifically, the method comprises modulating symbols associated with a first layer by using non-layered modulation scheme, and modulating symbols associated with a second layer and a third layer using a different layered-modulation scheme. Here, the symbols associated with the second layer and the third layer are multiplexed by any one of an orthogonal frequency division multiplexing, a code division multiplexing, a multi-carrier code division multiplexing, or a time division multiplexing.

    摘要: A method for receiving data at different frequencies includes receiving a first transmission packet including data at a first carrier frequency, and receiving a second transmission packet comprising data at a second carrier frequency. The method further includes maintaining communication with transmission entities which transmit the first and second transmission packets, and identifying reception quality of the first and second transmission packets. In addition, a method for retransmitting subpackets includes transmitting a first subpacket of a packet transmission from at least two transmitting entities. Upon receiving a non-acknowledgement NACK generated responsive to the first subpacket, the method further includes alternating transmission of subsequent subpackets from different transmitting entities. Upon receiving an acknowledgement ACK generated responsive to any subpackets of the packet transmission, the method further includes transmitting a first subpacket of a new packet transmission.

    摘要: A method and apparatus for randomizing access probes from co-located mobile terminals in order to reduce collisions is provided. By each mobile terminal or group of mobile terminals computing a random delay between a minimum delay value and a maximum delay value and using the random delay to delay the starting time of access probes, collisions between access probes from different mobile terminals may be reduced.
