Abstract
The present disclosure relates generally to wireless devices (e.g., Internet of Things (IoT) devices) and, more particularly, to improving the capacity of a logical channel such as the Random Access Channel (RACH) to cater to wireless traffic (e.g., IoT traffic). In one embodiment, a wireless device, when deciding to attempt a system access in accordance with the present disclosure, would first select a Training Sequence Code (TSC) based on the device's coverage class and then transmit one or more access request bursts (each including the selected TSC) on a logical channel to a wireless access node.
Claims20
A wireless device comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the wireless device is operable to:
- select a Training Sequence Code (TSC) based on a coverage class of the wireless device;
- and,
- transmit one or more access request bursts on a logical channel, wherein each of the one or more access request bursts includes the selected TSC.
A method implemented in a wireless device, the method comprising:
- selecting a Training Sequence Code (TSC) based on a coverage class of the wireless device;
- and,
- transmitting one or more access request bursts on a logical channel, wherein each of the one or more access request bursts includes the selected TSC.
A wireless access node configured to interface with a wireless device, the wireless access node comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the wireless access node is operable to:
- receive one or more access request bursts on a logical channel from the wireless device, wherein each of the one or more access request bursts includes a Training Sequence Code (TSC) associated with a coverage class of the wireless device.
A method in a wireless access node configured to interface with a wireless device, the method comprising:
- receiving one or more access request bursts on a logical channel from the wireless device, wherein each of the one or more access request bursts includes a Training Sequence Code (TSC) associated with a coverage class of the wireless device.
