1. A method performed by a first communication device, comprising:
determining, according to one or more property parameters of a service, whether to enable a channel acquisition function of the first communication device for the service, the channel acquisition function allowing the first communication device to acquire a channel for communications between the first communication device and a second communication device, the one or more property parameters of the service comprising at least one of:
a latency requirement of the service;
a quality of service related indicator specific to the service; and
a purpose of the service; and
performing traffic transmission for the service between the first communication device and the second communication device, based at least in part on the determination, performing the traffic transmission for the service between the first communication device and the second communication device comprising:
allowing the first communication device to acquire the channel for communications between the first communication device and the second communication device, in response to the determination of enabling the channel acquisition function of the first communication device for the service;
allowing the first communication device to transmit channel acquisition signaling in the channel acquired by the first communication device, the channel acquisition signaling comprising a copy of information content carried in subsequent transmission from the first communication device to the second communication device; and
transmitting the channel acquisition signaling in the channel acquired by the first communication device.
 
15. A method performed by a first communication device, the method comprising:
determining, according to one or more property parameters of a service, whether to enable a channel acquisition function of the first communication device for the service, the channel acquisition function allowing the first communication device to acquire a channel for communications between the first communication device and a second communication device, the one or more property parameters of the service comprising at least one of:
a latency requirement of the service;
a quality of service related indicator specific to the service; and
a purpose of the service; and
performing traffic transmission for the service between the first communication device and the second communication device, based at least in part on the determination, performing the traffic transmission for the service between the first communication device and the second communication device comprising:
allowing the first communication device to acquire the channel for communications between the first communication device and the second communication device, in response to the determination of enabling the channel acquisition function of the first communication device for the service; and
allowing the first communication device to transmit channel acquisition signaling in the channel acquired by the first communication device;
the channel acquisition signaling being pre-prepared and encoded to be transmitted in a packet data unit in at least one of a packet data unit, control signaling, random access signaling a reference signal and a paging method, and for the packet data unit carrying the channel acquisition signaling, an automatic repeat request process being applied based at least in part on another automatic repeat request process of subsequent transmission from the first communication device to the second communication device; and
transmitting the channel acquisition signaling in the channel acquired by the first communication device.
