OVERLAPPING DOWNLINK CONTROL CHANNEL AND CELL-SPECIFIC REFERENCE SIGNAL BANDWIDTHS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18331582 titled 'OVERLAPPING DOWNLINK CONTROL CHANNEL AND CELL-SPECIFIC REFERENCE SIGNAL BANDWIDTHS
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The abstract explains the following:
- A user equipment (UE) receives a configuration for a physical downlink control channel (PDCCH) associated with a first radio access technology (RAT).
- The PDCCH configuration includes a set of time-frequency resources and one or more control channel elements (CCEs).
- The UE also receives a configuration for a cell-specific reference signal (CRS) associated with a second RAT.
- The CRS configuration includes a second set of time-frequency resources that overlap with at least one CCE.
- The UE further receives a demodulation reference signal (DMRS) within a third set of time-frequency resources of a PDCCH.
- The DMRS configuration is identified based on the PDCCH configuration and the CRS configuration.
- The third set of time-frequency resources is included within the CCEs of the first set of time-frequency resources but excludes the second set of time-frequency resources.
Potential applications of this technology:
- Wireless communication systems and networks
- Mobile devices and user equipment
- Radio access technologies and protocols
Problems solved by this technology:
- Efficient allocation and utilization of time-frequency resources in wireless communication systems
- Coexistence and compatibility of multiple radio access technologies
- Accurate demodulation and decoding of control signals
Benefits of this technology:
- Improved performance and reliability of wireless communication systems
- Enhanced capacity and throughput in multi-RAT environments
- Seamless integration and interoperability of different radio access technologies
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives a physical downlink control channel (PDCCH) configuration associated with a first radio access technology (RAT), the PDCCH configuration for a first set of time-frequency resources including one or more control channel elements (CCEs). The UE receives a cell-specific reference signal (CRS) configuration associated with a second RAT, the CRS configuration for a second set of time-frequency resources that overlaps with at least one CCE. The UE receives a demodulation reference signal (DMRS) within a third set of time-frequency resources of a PDCCH in accordance with a DMRS configuration that is identified for the third set of time-frequency resources based on the PDCCH configuration and the CRS configuration, the third set of time-frequency resources included within the one or more CCEs of the first set of time-frequency resources exclusive of the second set of time-frequency resources.
