    摘要: A code combining soft handoff method is disclosed. A mobile terminal measures a strength of respective pilot signals received from a plurality of base stations. If the strength of the received pilot signal is higher than a given value, a base station controller allocates a new code pattern to the corresponding base station to additionally receive a signal from the base station. If the strength of the received pilot signal is lower than the specified value, it drops a signal of the corresponding base station. The mobile terminal and the base station change the code pattern of one of the signals from the two base stations into a code pattern different from the code pattern of the other signal.

    摘要: A flexible data rate matching method in a 3GPP2 system is disclosed that supports flexible data rate repetition on a physical layer of synchronous cdma2000 in an interleaving process. The process includes repeating bits of a channel encoded bitstream with one of a plurality of repetition factors, for matching a length of a repeated bitstream to an interleaving depth, or alternatively, fixing an index of an offset bit, where bit repetition of the channel encoded bitstream is started therefrom, for making the repetition pattern of the channel encoded bitstream to be a desired bit repetition pattern, fixing a repetition factor according to an initial parameter defined by the index of a fixed offset bit, repeating a bit of relevant index, and updating the initial parameter according to the fixed repetition factor, and repeating a process of fixing the repetition factor of a next bit according to the updated initial parameter, repeating the next bit, and re-updating the updated initial parameter, for matching a length of the repeated bitstream to the interleaving depth.

    摘要: Disclosed in a mobile communication system, and more particularly a method of re-transmitting data through a reverse link in a packet data system using ARQ (automatic repeat request) and a packet transmitting method and apparatus by which transmission efficiency is enhanced. The present invention discloses a method for re-transmitting data through a reverse link in Packet Data communication system using automatic repeat request (ARQ) adjusting data retransmission energy to be reduced at a predetermined ratio of one receiving energy for an initial data transmission to other receiving energy for a data re-transmission. The present invention also discloses a hybrid automatic repeat request system for packet transmission in which separate traffic-to-pilot power ratios are assigned to sub-packets when transmitting the sub-packets formed from one packet.

    摘要: The present invention relates to Walsh Code Allocation (WCA) field in the Packet Data Control Channel. One of the embodiments of the WCA field is use of the WCA field as Last Walsh Code Index (LWCI) field in the message format of the PDCCH. The LWCI field indicates the corresponding last code index or the corresponding number of Walsh codes in a Walsh Code Index (WCI) Table/List/Set. In alternative embodiments, the WCA indicates a general set of Walsh codes or a specific set of Walsh codes in the WCI table. The WCA fields may or may not be used with one of power ranking and sequential decoding, but is preferable used. The WCA field has various advantages including but not limited to efficient use of system resources.
