ASPECTS OF NEW RADIO PDCCH DESIGN - A simplified explanation of the abstract
This abstract first appeared for US patent application 17937661 titled 'ASPECTS OF NEW RADIO PDCCH DESIGN
Simplified Explanation
The present disclosure discusses the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. This includes various aspects such as multiple PDCCH search spaces, control resource block (CRB), irregular grants, and fast control channel signaling for grant-free uplink (UL).
- Multiple PDCCH search spaces can be defined for different scheduling entities, including common and/or user equipment (UE)-centric search spaces.
- Control resource blocks (CRBs) can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs).
- Irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots.
- Signaling can be used to indicate the portion of the resource pool available for grant-free UL to a UE configured for grant-free UL.
Potential Applications
- 5G new radio (NR) applications
- Wireless communication systems
- Mobile networks
Problems Solved
- Efficient implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications
- Optimization of resource allocation for grant-free uplink (UL)
- Improved scheduling and control mechanisms in wireless communication systems
Benefits
- Enhanced performance and efficiency in 5G new radio (NR) applications
- Improved resource allocation and utilization
- Faster and more reliable control channel signaling for grant-free uplink (UL)
Original Abstract Submitted
The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.
