Transmitting method, receiving method, transmitter, and receiver

A transmitting method, adapted for a transmitter in an user equipment (UE) for a data transmission scheme using a contention-based radio access based on single-carrier frequency division multiplexing access with code division multiplexing, comprising:

• selecting one of a plurality of parameters and generating a resource pattern by executing a resource pattern generation process according to the selected parameters, wherein the resource pattern includes a physical index of a plurality of resource blocks and a spreading code index;
• and
• generating and transmitting an uplink transmitting signal according to the resource pattern with a plurality of transmitting data bits.

A receiver, adapted for a control node of a data transmission scheme using a contention-based radio access based on single-carrier frequency division multiplexing access with code division multiplexing, comprising:

• a communication unit, receiving a transmitting signal, and detecting a reference signal in the transmitting signal;
• a processing unit, coupled to the communication unit, deriving a resource pattern by executing a resource pattern recognition process according to the transmitting signal and the reference signal, wherein the resource pattern comprising a physical index of a plurality of resource blocks and a spreading code index,
• wherein the communication unit receives the resource pattern from the processing unit, the communication unit further receives the transmitting signal by a code division multiplexing physical uplink channel receiving process according to the resource pattern to transfer the transmitting signal into a plurality of transmitting data bits.

The receiving method of 21, wherein at the step of transferring the transmitting signal into the transmitting data bits, the receiving method comprising:

• transferring the transmitting signal into the transmitting data bits according to the resource pattern derived by resource pattern recognition process and a code division multiplexing scheme without any additional information.
