Abstract
A method of performing machine-type communication (MTC) device access in a network of a wireless communication system is disclosed. The method comprises generating system information comprising a resource allocation dedicated to the MTC device access for a MTC device not capable of utilizing full system bandwidth of the network; and broadcasting the system information.
Claims14
A method of performing machine-type communication (MTC) device access in a communication network of a wireless communication system, the method comprising:
- the communication network generating a system information comprising a resource allocation dedicated to the MTC device access for a MTC device capable of a maximum bandwidth less than a cell bandwidth of the communication network, wherein the resource allocation comprises at least one random access preamble for the MTC device to transmit one of the at least one random access preamble or at least one resource location for the MTC device to transmit a random access preamble;
- the communication network broadcasting the system information;
- the communication network determining whether the random access preamble is sent according to the resource allocation from the MTC device;
- and
- the communication network transmitting a random access response (RAR) within the communication device capable bandwidth to the MTC device according to the determination, wherein the random access preamble is selected from the at least one random access preamble in the resource allocation or sent on a resource location in the resource allocation.
