COMMON SEARCH SPACE FOR MACHINE TYPE COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17075627 titled 'COMMON SEARCH SPACE FOR MACHINE TYPE COMMUNICATIONS
Simplified Explanation
The patent application is about search space configuration in wireless communication systems, specifically for devices with limited communication resources like machine type communication (MTC) devices and enhanced MTC (eMTC) devices.
- The method involves receiving a physical random access channel (PRACH) signal from a user equipment (UE) on a narrowband region within a wider system bandwidth.
- In response to the PRACH signal, a random access response (RAR) signal is transmitted in a first search space in a different narrowband region in at least one subframe.
Potential Applications
This technology can be applied in various wireless communication systems, especially those utilizing devices with limited communication resources like MTC and eMTC devices. Some potential applications include:
- Internet of Things (IoT) networks

Original Abstract Submitted
Certain aspects of the present disclosure generally relate to wireless communications and more specifically to search space configuration in systems utilizing devices with limited communications resources, such as machine type communication (MTC) devices and enhanced MTC (eMTC) devices. An example method generally includes receiving a physical random access channel (PRACH) signal from a first user equipment (UE) on a first narrowband region within a wider system bandwidth and transmitting, in response to the PRACH signal, a random access response (RAR) signal in a first search space in a second narrowband region in at least a first subframe.
