Handling High Data Rates in Protocol Stack when Using High Frequency Spectrum - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240205724 titled 'Handling High Data Rates in Protocol Stack when Using High Frequency Spectrum
The patent application describes a protocol stack that can accommodate both high frequency carriers and lower frequency carriers by including a radio link control (RLC) entity that allows configuration of status reporting control parameters on a per carrier or per subcarrier spacing basis. Alternatively, the protocol stack may include two RLC entities, one for high frequency carriers and another for lower frequency carriers, distinguished based on a frequency threshold. Additionally, a user equipment may transmit an indication of its L2 buffer size to the network, which can then configure the UE and/or control scheduling to prevent buffer overrun. The UE may also indicate it can support a percentage of a maximum buffer size, with the network configuring the UE and/or control scheduling to ensure the buffer occupancy does not exceed the specified percentage.
- The protocol stack includes a radio link control (RLC) entity for configuring status reporting control parameters on a per carrier or per subcarrier spacing basis.
- Two RLC entities may be included in the protocol stack, one for high frequency carriers and another for lower frequency carriers, distinguished by a frequency threshold.
- User equipment can transmit an indication of its L2 buffer size to the network for configuration and control scheduling to prevent buffer overrun.
- User equipment may indicate it can support a percentage of a maximum buffer size, with the network configuring control scheduling to maintain buffer occupancy below the specified percentage.
Potential Applications: - Wireless communication systems - Mobile networks - Internet of Things (IoT) devices
Problems Solved: - Efficient management of high and low frequency carriers - Prevention of buffer overrun in user equipment - Optimal control scheduling for buffer occupancy
Benefits: - Improved performance in mixed carrier frequency environments - Enhanced network reliability - Efficient resource utilization
Commercial Applications: Title: "Advanced Protocol Stack for Mixed Carrier Frequency Environments" This technology can be utilized in telecommunications companies, IoT device manufacturers, and network infrastructure providers to enhance the efficiency and reliability of wireless communication systems.
Prior Art: Further research can be conducted in the field of radio link control entities in protocol stacks for wireless communication systems.
Frequently Updated Research: Stay updated on advancements in radio link control protocols and buffer management techniques in wireless networks.
Questions about the technology: 1. How does the protocol stack differentiate between high frequency and low frequency carriers for efficient management? 2. What are the implications of user equipment indicating its buffer size to the network for control scheduling and configuration?
Original Abstract Submitted
to accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (rlc) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. alternatively, a protocol stack may include two rlc entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (high frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) furthermore, a user equipment may transmit (to the network) an indication of its l2 buffer size. the network may configure the ue and/or control scheduling, to ensure the ue's l2 buffer does not overrun. alternatively, the ue may indicate that it can support a percentage of a maximum buffer size. the network may configure the ue and/or control scheduling so that the ue's buffer occupancy does not exceed the percentage.
