摘要

A method for wireless transmission of data packets in code division multiple access communication system and communication system with transmitter-receiver of a transmitting station on mobile site in a code division multiple access communication system where one of the channels with code division multiple access is used on time division basis to transmit data packets from many transmitters to a receiver characterised by a fact, that a request is sent from a transmitting station (Msy) to appropriate receiving station (BS) of a communication system, this request indicates a target address a packet or packets of data are to be directed to. This station is assigned a unique virtual connection identifier (VCIy), switches a transmitting station (Msy) to a (PRCH) channel with code division multiple access for transmitting data packets a downstream link on a code division multiple access channel (PRCH) is monitored, until a base station (BS) broadcasts that it will be free and in the next frame free access to a code division multiple access channel (PRCH) will be permitted, a power of a transmitting station (Msy) is increased during the next frame until a given power is attained, a data packet or packets and a virtual connection identifier (VCIy) are transmitted through an upstream link of a code division multiple access channel (PRCH) for transmission of data packets to a base station (BS) and a data packet or packets are redirected again to a target address with an access to code division multiple access channel (PRCH) for transmission of data packets is controlled by a multiple access protocol based on carrier detection and collision detection.
