Abstract: A method and system for dynamic adjustment of downlink/uplink resource allocation ratio in a long-term evolution (LTE) time division duplex (TDD) system is disclosed. The method includes replacing at least one uplink subframe in a subframe pattern with at least one of a mute subframe and a mute uplink pilot timeslot (UpPTS), within a geographical guard area that isolates at least two areas having different TDD allocation patterns. The method further includes scheduling an uplink transmission from at least one mobile terminal such that the at least one of the mute subframe and the mute UpPTS are unused. A simple solution or a TDD configuration index substitution solution, or any combination thereof, may be used to control the uplink transmission involving a mute subframe or a mute UpPTS.

The terminal random access method for a cellular radio communications system includes steps of: transmitting random access preamble message by a terminal to a base station in a random access time slot in a radio frame; combining location information of the random access time slot in the radio frame and that in the frequency domain to generate a group identifier and sending a random access response message to the terminal after adding the group identifier and an individual identifier that corresponds to the random access preamble message to the random access response message by the base station; judging whether the random access response message that corresponds to the sent random access preamble message is received, by judging whether the group identifier and the individual identifier within the received random access response message are all expected values. This invention provides fast and accurate access to the cellular radio communications system for the terminal and allows simple and easy operations to set a group identifier in the same way regardless of whether or not the configuration of the random access time slot changes.
