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 20240205723 titled 'Handling High Data Rates in Protocol Stack when Using High Frequency Spectrum

The abstract of the patent application describes a protocol stack that can accommodate a mix of 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. 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 its support for 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.
• Alternatively, the protocol stack may have two RLC entities, one for high frequency carriers and another for lower frequency carriers.
• User equipment can transmit indications of its L2 buffer size to the network for configuration and control scheduling to prevent buffer overrun.
• The network can configure the UE based on a percentage of a maximum buffer size to ensure buffer occupancy does not exceed the specified percentage.

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.
