Title:
WIRELESS BASE SYSTEM AND TRANSMISSION TIMING CONTROL METHOD
Document Type and Number:
Japanese Patent JP3475166
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a wireless base system that can suppress deterioration in speech characteristics of users in path multiple connection and crosstalk among the users and to provide a transmission timing control method.
SOLUTION: In the case of a slot with low multiplicity, multiplicity for a new user is prepared by compacting transmission timings of already connected users. On the other hand, in the case of a slot with high multiplicity, multiplicity for the new user is not prepared by keeping transmission timing intervals of already connected users at maximum. As a result, the preparation slot for the new user can be provided while taking a transmission timing as wide as possible. Furthermore, keeping the transmission timing intervals of the already connected users at a maximum can prevent deterioration in the characteristics and moving the transmission timing of the new user during a control channel period can realize an optimum transmission timing interval at the setup of a speech channel. A DSP 14 executes the processing above.
