Abstract
A wireless device may use power ramping for transmissions of message preambles and/or transport blocks. A first ramped transmission power may be used to transmit a preamble of a message, and a second ramped transmission power may be used to transmit a transport block of the message. Channel access procedures may be used to determine clear channel or busy channel for transmissions.
Claims30
A method comprising:
- performing, by a wireless device, a first channel access procedure for transmission of a first preamble of a message;
- performing a second channel access procedure for transmission of a first transport block of the message;
- transmitting, based on the first channel access procedure indicating a clear channel and the second channel access procedure indicating a busy channel, a portion of the message comprising the first preamble;
- based on an expiration of a time duration for reception of the message:
- transmitting, using a first ramped transmission power, a second preamble;
- and
- transmitting, using a second ramped transmission power, the first transport block.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause configure the wireless device to:
- perform a first channel access procedure for transmission of a first preamble of a message;
- perform a second channel access procedure for transmission of a first transport block of the message;
- transmit, based on the first channel access procedure indicating a clear channel and the second channel access procedure indicating a busy channel, a portion of the message comprising the first preamble;
- based on an expiration of a time duration for reception of the message:
- transmit, using a first ramped transmission power, a second preamble;
- and
- transmit, using a second ramped transmission power, the first transport block.
A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
- perform a first channel access procedure for transmission of a first preamble of a message;
- perform a second channel access procedure for transmission of a first transport block of the message;
- transmit, based on the first channel access procedure indicating a clear channel and the second channel access procedure indicating a busy channel, a portion of the message comprising the first preamble;
- based on an expiration of a time duration for reception of the message:
- transmit, using a first ramped transmission power, a second preamble;
- and
- transmit, using a second ramped transmission power, the first transport block.
