Abstract
Systems, apparatuses, and methods are described for wireless communications. Random access procedures may include various steps, such as 4-steps or 2-steps. One or more indicators such as, for example, transmission power requirements, may be used to indicate which random access procedure to utilize.
Claims40
A method comprising:
- transmitting, by a wireless device and using a first transmission power, a first message comprising a first preamble and comprising a transport block;
- based on a determination that a calculated transmission power associated with transmission of a second message does not satisfy a transmission power threshold, using a second transmission power to transmit the second message, wherein the second message comprises a second preamble, and wherein the second transmission power was adjusted from the calculated transmission power to satisfy the transmission power threshold;
- and
- based on receiving a random access response to the second message, retransmitting the transport block.
1 more element
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- transmit, using a first transmission power, a first message comprising a first preamble and comprising a transport block;
- based on a determination that a calculated transmission power associated with transmission of a second message does not satisfy a transmission power threshold, use a second transmission power to transmit the second message, wherein the second message comprises a second preamble, and wherein the second transmission power was adjusted from the calculated transmission power to satisfy the transmission power threshold;
- and
- based on receiving a random access response to the second message, retransmit the transport block.

A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:
- transmit, using a first transmission power, a first message comprising a first preamble and comprising a transport block;
- based on a determination that a calculated transmission power associated with transmission of a second message does not satisfy a transmission power threshold, use a second transmission power to transmit the second message, wherein the second message comprises a second preamble, and wherein the second transmission power was adjusted from the calculated transmission power to satisfy the transmission power threshold;
- and
- based on receiving a random access response to the second message, retransmit the transport block.
1 more element
A system comprising:
- a base station;
- and
- a wireless device, wherein the wireless device is configured to:
- transmit, using a first transmission power, a first message comprising a first preamble and comprising a transport block;
- based on a determination that a calculated transmission power associated with transmission of a second message does not satisfy a transmission power threshold, use a second transmission power to transmit the second message, wherein the second message comprises a second preamble, and wherein the second transmission power was adjusted from the calculated transmission power to satisfy the transmission power threshold;
- and
- based on receiving a random access response to the second message, retransmit the transport block, and
- wherein the base station is configured to transmit the random access response.
