Transmitting/receiving apparatus using a plurality of spreading codes
First Claim
1. A transmitting/receiving apparatus for performing transmission and reception of voice required of real time nature and data not required of real time nature by using a plurality of spreading codes, comprising:
- means for designating more spreading codes for transmission of the data than for transmission of the voice to a forward link from a base station to a mobile station; and
means for transmitting a control signal for a request for retransmission of the data by using a reverse link for voice from said mobile station to said base station.

Abstract
Transmitting/receiving apparatuses are installed in a base station and a mobile station, respectively, to perform mutual transmission and reception by using a plurality of spreading codes. The transmitting/receiving apparatus installed in the base station has a block for designating to the mobile station the kind and the number of spreading codes used in a reverse link from the mobile station to the base station through a forward link at the time that communication with the mobile station is started. The transmitting/receiving apparatus installed in the mobile station has a block for transmitting a signal to the base station by using spreading codes of the designated kind and number. The transmitting/receiving apparatus installed in the base station further has a block for detecting receiving quality values of the signal transmitted from the mobile station with respect to individual spreading codes used in the mobile station, a block for deciding whether or not the detected receiving quality values exceed a prescribed quality value, and a block for finally setting the kind and number of spreading codes to be used in the reverse link on the basis of the spreading codes for which the detected receiving quality values are determined to exceed the prescribed quality value.
