  • Patent number: 8149684
    Abstract: The code space associated with the communication system is divided into at least two subspaces where each subspace is assigned to a different mode of operation. In one mode, such as a voice mode, each user is given full time access to a portion of the subspace associated with that mode of operation. In a second mode, such as a data mode, each user uses the entire subspace associated with that mode on a time shared basis.

  • Patent number: 8144651
    Abstract: When a radio resource allocation channel transmitted from a radio base station (eNB) at a discontinuous reception timing satisfies a specific condition, a mobile station (UE) is configured not to start a continuous reception of a signal transmitted from the radio base station (eNB), but to continue the discontinuous reception of a signal transmitted from the radio base station (eNB), even though the mobile station (UE) is performing the discontinuous reception of a signal transmitted from the radio base station (eNB).

  • Patent number: 8102834
    Abstract: A method for reporting and managing wireless resources in TDM system comprises the step of reporting the wireless resources comprises a RNC obtaining the resource capacity information of each of the carrier frequency in a cell covered by a base station through the resource audit response message or the resource state indicating message or the resource obstruct message. The RNC can obtain the information of the carrier frequency. According to the method, resource capacity information of each of the carrier frequency in the RNC is in consistency of that of the base station. Thus, the rationality of the carrier frequency and the resource capacity information of the carrier frequency distributed to the service by the RNC can be assured. The success rate of the establishment for a radio link is improved accordingly as to avoid the fact that the radio link establishes on the carrier frequency that is not supported by the base station.

  • Patent number: 8089924
    Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

  • Patent number: 8085704
    Abstract: The present invention relates to methods and apparatuses as well as a measurement report signal for reporting measurements on ranging signals (RS1-RS4) received by a mobile station from satellites (SV1-SV4) or calculating a position based on such measurements, wherein each of said ranging signal comprises a stream (201) of data bits (202) spread by a spreading code (203). After synchronizing (501) to data bit edges in the stream of data bits on a ranging signal, a position in time modulo the data bit length for said stream of data bits with respect to a selected point in time is measured (502). The measured position in time could be used by the apparatus performing the measurements on the received ranging signals for calculating (504) the position of the mobile station. Alternatively the apparatus could transmit (503) a wireless signal including data representing said measured position in time, allowing the mobile station position to be determined in another apparatus (101).
