System, Apparatus and Methods for Hybrid Functional Splits Design with Support for Advanced Features in Cellular Networks
A method and computer readable media are described for providing hybrid functional splits for a system. In one example embodiment a method includes defining, for a system having a Radio Unit (RU) and a Distributed Unit (DU) a Centralized Unit (CU) and an interface protocol between the RU to the DU and to the CU, a plurality of split options for balancing computer power and spectral efficiency, the plurality of split options including a split option 6 in which users are served by a single cell; and a split option 7.x in which users are served by multi-cell joint processing.
1 . A method for providing hybrid functional splits for a system, the method comprising:
defining, for a system having a Radio Unit (RU) and a Distributed Unit (DU) a Centralized Unit (CU) and an interface protocol between the RU to the DU and to the CU, a plurality of split options for balancing computer power and spectral efficiency, the plurality of split options including
a split option 6 in which users are served by a single cell and
a split option 7.x in which users are served by multi-cell joint processing; and
running, by at least one of the DU or CU, at least one cellular protocol stack software (SW).
2 . The method of claim 1 further comprising aggregating, by the RU, Radio Frequency (RF) capability and compute platform.
3 . The method of claim 1 wherein running at least one cellular protocol stack SW includes providing interfacing capabilities to one or more RUs distributed in space or co-located.
4 . The method of claim 1 wherein running at least one cellular protocol stack SW includes providing a scheduling mechanism to decide when to apply single or joint processing of the data.
5 . The method of claim 1 further comprising running PHY-manager management logic exercising split option 6 or 7.x based on the required processing capabilities.
6 . The method of claim 1 further comprising distributing, by the PHY manager, single PHY processing data and control data to the RU, and wherein the RU exercises split option 6 functionality.
7 . The method of claim 6 further comprising a rest of the data path packets required for joint processing exercise split option 7.x.
8 . The method of claim 7 further comprising processing a rest of the upper PHY in the DU or CU.
9 . A non-transitory computer-readable medium containing instructions for providing hybrid functional splits for a system which, when executed, cause the system to perform steps comprising:
defining, for a system having a Radio Unit (RU) and a Distributed Unit (DU) a Centralized Unit (CU) and an interface protocol between the RU to the DU and to the CU, a plurality of split options for balancing computer power and spectral efficiency, the plurality of split options including
a split option 6 in which users are served by a single cell and
a split option 7.x in which users are served by multi-cell joint processing; and
running, by at least one of the DU or CU, at least one cellular protocol stack software (SW).
10 . The computer-readable medium of claim 9 further comprising instructions for aggregating, by the RU, Radio Frequency (RF) capability and compute platform.
11 . The computer-readable medium of claim 9 wherein the instructions for running at least one cellular protocol stack SW include instructions for providing interfacing capabilities to one or more RUs distributed in space or co-located.
12 . The computer-readable medium of claim 9 wherein the instructions for running at least one cellular protocol stack SW includes instructions for providing a scheduling mechanism to decide when to apply single or joint processing of the data.
13 . The computer-readable medium of claim 9 further comprising instructions for running PHY-manager management logic exercising split option 6 or 7.x based on the required processing capabilities.
14 . The computer-readable medium of claim 9 further comprising instructions for distributing, by the PHY manager, single PHY processing data and control data to the RU, and wherein the RU exercises split option 6 functionality.
15 . The computer-readable medium of claim 14 further comprising instructions for a rest of the data path packets required for joint processing exercise split option 7.x.
16 . The computer-readable medium of claim 15 further comprising instructions for processing a rest of the upper PHY in the DU or CU.
