Random Access Response Method, Base Station and Terminal

A random access response method, the method comprising:

• determining a random access preamble to be sent in an enhanced manner;
• determining at least one of level information or resource information corresponding to the random access preamble, wherein the level information comprises at least one of a level, a level index, an enhancement level, an enhancement level index, a repetition level, a repetition level index, a repetition count, a resource level, a resource level index, a resource set level, a resource set level index, a resource set index, a time resource set index, a frequency resource set index, a preamble index, a preamble group index, or a channel quality characterization parameter, and the resource information comprises at least one of a time-frequency resource index, a resource index, a random access opportunity index, a physical random access channel (PRACH) mask index, a time resource startpoint index, a time resource index, a frequency resource index, or a first PRACH index of a first subframe in which a PRACH carrying the random access preamble is located, and wherein a quantity of values of the first PRACH index of the first subframe in which the PRACH carrying the random access preamble is located is a positive integer greater than 6;
• sending the random access preamble in the enhanced manner;
• and
• receiving a random access response (RAR) of the random access preamble according to the at least one of the level information or the resource information, wherein the RAR is carried by a physical downlink shared channel (PDSCH).

A base station, wherein the base station comprises a receiving unit, a determining unit, and a sending unit, wherein

• the receiving unit is configured to receive a random access preamble sent in an enhanced manner;
• the determining unit is configured to determine at least one of level information or resource information corresponding to the random access preamble that is sent in the enhanced manner and that is received by the receiving unit, wherein the level information comprises at least one of a level, a level index, an enhancement level, an enhancement level index, a repetition level, a repetition level index, a repetition count, a resource level, a resource level index, a resource set level, a resource set level index, a resource set index, a time resource set index, a frequency resource set index, a preamble index, a preamble group index, or a channel quality characterization parameter, and the resource information comprises at least one of a time-frequency resource index, a resource index, a random access opportunity index, a physical random access channel (PRACH) mask index, a time resource startpoint index, a time resource index, a frequency resource index, or a first PRACH index of a first subframe in which a PRACH carrying the random access preamble is located, and wherein a quantity of values of the first PRACH index of the first subframe in which the PRACH carrying the random access preamble is located is a positive integer greater than 6;
• and
• the sending unit is configured to send a random access response (RAR) of the random access preamble according to the at least one of the level information or the resource information determined by the determining unit, wherein the RAR is carried by a physical downlink shared channel (PDSCH).

A terminal UE, wherein the UE comprises a determining unit, a sending unit, and a receiving unit, wherein

• the determining unit is configured to determine a random access preamble to be sent in an enhanced manner, and determine at least one of level information or resource information corresponding to the random access preamble, wherein the level information comprises at least one of a level, a level index, an enhancement level, an enhancement level index, a repetition level, a repetition level index, a repetition count, a resource level, a resource level index, a resource set level, a resource set level index, a resource set index, a time resource set index, a frequency resource set index, a preamble index, a preamble group index, or a channel quality characterization parameter, and the resource information comprises at least one of a time-frequency resource index, a resource index, a random access opportunity index, a physical random access channel (PRACH) mask index, a time resource startpoint index, a time resource index, a frequency resource index, or a first PRACH index of a first subframe in which a PRACH carrying the random access preamble is located, and wherein a quantity of values of the first PRACH index of a first subframe in which the PRACH carrying the random access preamble is located is a positive integer greater than 6;
• the sending unit is configured to send, in the enhanced manner, the random access preamble determined by the determining unit;
• and
• the receiving unit is configured to receive a random access response (RAR) of the random access preamble according to the at least one of the level information or the resource information determined by the determining unit, wherein the RAR is carried by a physical downlink shared channel (PDSCH).
