[0019] It can be seen that the transmission method of terminal wireless access capability information is complex and inefficient, and the same capability parameter or category is repeatedly transmitted.
Especially when initially applying for access, it is necessary to select the necessary terminal wireless access capability information parameters or categories and put them into the "radio resource control connection establishment request" signaling. Errors and omissions often occur, resulting in frequent changes to the protocol description and instability.

Embodiment Construction
[0038] A method of using control signaling to transmit terminal wireless access capability information in random access, wherein the terminal uses the first control signaling on the uplink resource of the shared data channel assigned by the access network to carry all complete terminal wireless access capabilities. In the way of capability information, the wireless access capability information of the terminal is transmitted to the access network.
[0039] Below in conjunction with accompanying drawing 3 the method of the present invention is described further:
[0040] Step 110, the terminal sends an access preamble to the access network on a physical random access channel, requesting access;
[0041] Step 120, the access network responds to the terminal with time adjustment information for uplink transmission timing;
[0042] Step 130, the access network responds to the terminal with uplink resource information for transmitting uplink data or control signaling on the assign...

The utility model discloses a method that transmits the information of terminal wireless access capacity through control signaling in random access, which is characterized in that the time is adjusted according to the direction of the access network after the terminal is accessed in layer 1; the terminal transmits forward data or control signaling according to the forward resources of shared data channel designated by the access network, and passes the information of terminal wireless access capacity to the access network in the control signaling sent to the access network.
Description
technical field [0001] The present invention relates to a design method of a random access process in a wireless communication system, in particular to a design method for transmission of terminal wireless access capability information in the random access process. Background technique [0002] The terminal wireless access capability information describes the specific capability of the terminal to access the wireless communication system and the specific capability of using the wireless resources of the wireless communication system. Different terminals may have different terminal wireless access capabilities, and the access network selects a suitable wireless access method and configuration of wireless resources for the terminal according to the limitation of the terminal wireless access capabilities. [0003] The terminal wireless access capability information may be represented by a specific parameter set representing the terminal wireless access capability, or may be rep...
