Abstract
Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold. The UE performs congestion control based on the energy-based CBR by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR.
Claims30
A method of wireless communication by a user equipment (UE), comprising:
- determining an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold;
- and
- performing congestion control based on the energy-based CBR and a channel resource utilization limit for the UE by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR, the channel resource utilization limit being a function of a CBR limit.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold;
- and
- perform congestion control based on the energy-based CBR and a channel resource utilization limit for the UE by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR, the channel resource utilization limit being a function of a CBR limit.
A user equipment (UE) for wireless communication, comprising:
- means for determining an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold;
- and
- means for performing congestion control based on the energy-based CBR and a channel resource utilization limit for the UE by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR, the channel resource utilization limit being a function of a CBR limit.
A non-transitory computer-readable medium storing computer executable code, comprising code to:
- determine an energy-based channel busy ratio (CBR) based on a number of probes on a set of radio resources having respective energy levels greater than an energy threshold;
- and
- perform congestion control based on the energy-based CBR and a channel resource utilization limit for the UE by adjusting at least one transmission parameter of one or more transmission parameters or transmission power of the UE based on the energy-based CBR, the channel resource utilization limit being a function of a CBR limit.
