Method and apparatus for sending and receiving random access response in a wireless communication system

An apparatus for wireless communication, comprising:

• at least one processor configured to transmit a random access (RA) preamble for random access, and to receive a random access response comprising a first part and a second part, the first part comprising a list of N RA preamble identifiers (IDs) for N RA preambles being responded to by the random access response, and the second part comprising N individual RA responses for the N RA preambles, where N is a value of one or greater.

An apparatus for wireless communication, comprising:

• means for transmitting a random access (RA) preamble for random access;
• and
• means for receiving a random access response comprising a first part and a second part, the first part comprising a list of N RA preamble identifiers (IDs) for N RA preambles being responded to by the random access response, and the second part comprising N individual RA responses for the N RA preambles, where N is a value of one or greater.

A computer program product, comprising:

• a computer-readable medium comprising:
• code for causing at least one computer to transmit a random access (RA) preamble for random access, and
• code for causing the at least one computer to receive a random access response comprising a first part and a second part, the first part comprising a list of N RA preamble identifiers (IDs) for N RA preambles being responded to by the random access response, and the second part comprising N individual RA responses for the N RA preambles, where N is a value of one or greater.

A method for wireless communication, comprising:

• receiving at least one random access (RA) preamble from at least one user equipment (UE) for random access;
• and
• transmitting a random access response comprising a first part and a second part, the first part comprising a list of N RA preamble identifiers (IDs) for N RA preambles being responded to by the random access response, and the second part comprising N individual RA responses for the N RA preambles, where N is a value of one or greater.
