1. A wireless communication method by a first wireless communication device, comprising:
transmitting, by the first wireless communication device to a second wireless communication device, a first message; and
after the first wireless communication device transmits the first message to the second wireless communication device and the first wireless communication device receives a second message relevant to the first message from the second wireless communication device, the first wireless communication device transmits a data transmission to the second wireless communication device,
wherein the second message is a pre-configured sequence or a pre-defined sequence,
wherein the second message is carried in a PUCCH format 0 or a PUCCH format 1,
wherein the second message comprises a clear to send (CTS) message, which is an acknowledgement of receiving a corresponding first massage,
wherein the CTS message indicates that the second wireless communication device has performed a successful channel access on one or more channels,
wherein the CTS message comprises a set of bits, where each bit corresponds to an outcome of channel access failure or success on a dedicated channel or a dedicated carrier,
wherein when the channel access is successful, the corresponding bit is set to a pre-defined value,
wherein a number of bits contained in the CTS message is indicated by a corresponding request to send (RTS) message,
wherein when the first wireless communication device controls the second wireless communication device to receive a first RTS on a first carrier or a first serving cell and a second RTS on a second carrier or a second serving cell, both the first RTS and the second RTS request a same CTS transmission,
wherein the first wireless communication device is configured to control the second wireless communication device to transmit a CTS message in the CTS, which contains an acknowledgement to the first RTS and the second RTS,
wherein the RTS message comprises an indication corresponding to a location of an acknowledgement bit in the CTS message,
wherein the first RTS indicates that the CTS contains 2 acknowledgement bits and an acknowledgement bit corresponding to the first RTS is located in a first bit,
wherein the second RTS indicates that the CTS contains 2 acknowledgement bits and an acknowledgement bit corresponding to the second RTS is located in a second bit.
 
5. A wireless communication method by a second wireless communication device, comprising:
receiving, by the second wireless communication device from a first wireless communication device, a first message; and
after the second wireless communication device receives the first message from the first wireless communication device and the second wireless communication device transmits a second message relevant to the first message to the first wireless communication device, the second wireless communication device receives a data transmission from the first wireless communication device,
wherein the second message is a pre-configured sequence or a pre-defined sequence,
wherein the second message is carried in a PUCCH format 0 or a PUCCH format 1, wherein the second message comprises a clear to send (CTS) message, which is an acknowledgement of receiving a corresponding first massage
wherein the CTS message indicates that the second wireless communication device has performed a successful channel access on one or more channels,
wherein the CTS message comprises a set of bits, where each bit corresponds to an outcome of channel access failure or success on a dedicated channel or a dedicated carrier,
wherein when the channel access is successful, the corresponding bit is set to a pre-defined value,
wherein a number of bits contained in the CTS message is indicated by a corresponding request to send (RTS) message,
wherein when the second wireless communication device receives a first RTS on a first carrier or a first serving cell and a second RTS on a second carrier or a second serving cell, both the first RTS and the second RTS request a same CTS transmission,
wherein the second wireless communication device is configured to transmits a CTS message in the CTS, which contains an acknowledgement to the first RTS and the second RTS,
wherein the RTS message comprises an indication corresponding to a location of an acknowledgement bit in the CTS message,
wherein the first RTS indicates that the CTS contains 2 acknowledgement bits and an acknowledgement bit corresponding to the first RTS is located in a first bit,
wherein the second RTS indicates that the CTS contains 2 acknowledgement bits and an acknowledgement bit corresponding to the second RTS is located in a second bit.
