Method of transmission of a data frame from a first station to a second station, and a CDMA telecommunications network

摘要

A method is provided of transmission of a data frame from a first station to a second station, in a code division multiple access (CDMA) telecommunications network. The network operates according to a hierarchical series of protocol processes including a physical layer process under the control of a radio link control (RLC) process. An indication of when a data frame is passed to the physical layer process for transmission to the second station is sent to the RLC process in the first station. Upon receipt of the indication the RLC process, a timer is started to time a predetermined period before again passing the data frame to the physical layer process for retransmission to the second station unless an acknowledgement of receipt from the second station is received.
