Abstract
Methods and apparatuses for random access transmission. A method implemented in a terminal device in a wireless communication system. According to the method, a random access request including a training sequence is generated. The training sequence is configured at least partially based on a requirement of a coverage gain for a predetermined coverage class five (CC5) of the terminal device. The random access request is transmitted to a network device on a random access channel.

A method implemented in a terminal device in a wireless communication system, comprising:
- generating a random access request including a training sequence, wherein the training sequence is configured at least partially based on a requirement of a coverage gain for a predetermined coverage class five (CC5) of the terminal device, and wherein the training sequence is configured as 1 1 1 0 1 1 1 0 1 1 0 0 0 1 1 1 0 0 0 0 0 1 0 0 1 1 1 1 0 1 0 0 1 0 0 1 1 1 0 0 1 0 0 0 1 1 0 1 1 0 1 0 0 1 1 1 0 0 0 1 1 1 1 0 1 0 1 0 1 0 1 1 0 1 1 0 0 1 0 1 1 1 0 0 0 1 1 1 0 1 1 1 1 1 1 1 1 0 1 0 1 1 0 1 0 1 1 1 0 1 0 0 0 0 0 1 1 0 1 1 0 1 1 1 1 1 0 1 1 1 1 0 0 1 1 1 0 0 1 0;
- and
- transmitting, to a network device, the random access request on a random access channel.
A method implemented in a network device in a wireless communication system, comprising:
- receiving a random access request from a terminal device on a random access channel;
- and
- detecting a training sequence in the random access request, wherein the training sequence is configured at least partially based on a requirement of a coverage gain for a predetermined coverage class five (CC5) of the terminal device, and wherein the training sequence is configured as 1 1 1 0 1 1 1 0 1 1 0 0 0 1 1 1 0 0 0 0 0 1 0 0 1 1 1 1 0 1 0 0 1 0 0 1 1 1 0 0 1 0 0 0 1 1 0 1 1 0 1 0 0 1 1 1 0 0 0 1 1 1 1 0 1 0 1 0 1 0 1 1 0 1 1 0 0 1 0 1 1 1 0 0 0 1 1 1 0 1 1 1 1 1 1 1 1 0 1 0 1 1 0 1 0 1 1 1 0 1 0 0 0 0 0 1 1 0 1 1 0 1 1 1 1 1 0 1 1 1 1 0 0 1 1 1 0 0 1 0.
An apparatus at a terminal device in a wireless communication system, comprising:
- a processor;
- and
- a memory coupled to the processor and storing instructions thereon, the instructions, when executed by the processor, cause the apparatus to:
- generate a random access request including a training sequence, wherein the training sequence is configured at least partially based on a requirement of a coverage gain for a predetermined coverage class five (CC5) of the terminal device, and wherein the training sequence is configured as 1 1 1 0 1 1 1 0 1 1 0 0 0 1 1 1 0 0 0 0 0 1 0 0 1 1 1 1 0 1 0 0 1 0 0 1 1 1 0 0 1 0 0 0 1 1 0 1 1 0 1 0 0 1 1 1 0 0 0 1 1 1 1 0 1 0 1 0 1 0 1 1 0 1 1 0 0 1 0 1 1 1 0 0 0 1 1 1 0 1 1 1 1 1 1 1 1 0 1 0 1 1 0 1 0 1 1 1 0 1 0 0 0 0 0 1 1 0 1 1 0 1 1 1 1 1 0 1 1 1 1 0 0 1 1 1 0 0 1 0;
- and
- transmit, to a network device, the random access request on a random access channel.
