A method of identifying a space-time encoded signal in a wireless communication system having at least two different decoder types is disclosed. The method includes receiving at least one pilot signal from a transmitting end, wherein the pilot signal is represented by either Type 0 or Type 1, determining which of Type 0 or Type 1 is represented in the received pilot signal, and activating the space-time decoder for performing space-time decoding, if the pilot signal is Type 1.

A method of transmitting data by at least one access terminal (AT) in a wireless communication system is disclosed. More specifically, the method includes ceasing all transmissions by the at least one AT during a duration corresponding to a duration used by an access node (AN) to transmit a superframe preamble, wherein the superframe comprises a plurality of physical frames.
摘要:
A method of transmitting at least one sub-packet in a wireless communication system is disclosed. More specifically, the method includes transmitting at least one sub-packet based on combination of resources from multiple domains, wherein the combination of resources indicate whether to maintain or change the resource arrangement for subsequent transmission.

A method of providing a point-to-multipoint service in a mobile communication system and transmission controlling method thereof are disclosed, by which a better quality of a point-to-multipoint service can be provided in a manner of coping with time-variable channel situation variable adaptively. In a mobile communication system providing a point-to-multipoint service, the present invention includes the steps of receiving data for the point-to-multipoint service from a base station, measuring a reception quality for the received point-to-multipoint service data, and transmitting reception quality information for the point-to-multipoint service data to the base station.
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.
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 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.
