OPERATION MODE INDICATION METHOD, APPARATUS, AND SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18155881 titled 'OPERATION MODE INDICATION METHOD, APPARATUS, AND SYSTEM
Simplified Explanation
The patent application describes a method and apparatus for indicating the operation mode of a terminal device with multiple antennas. This solves the problem of increased power consumption and resource waste when a terminal device operates in a multi-user multiple-input multiple-output (MU-MIMO) mode by default in a single-port transmission mode.
- The network device sends indication information to the terminal device to specify whether the multi-antenna operation mode should be single-user multiple-input multiple-output (SU-MIMO) or MU-MIMO.
- The terminal device uses the indication information to determine if a demodulation reference signal (DMRS) port number allocated to it is also allocated to another terminal device.
- Based on this determination, the terminal device adjusts its multi-antenna operation mode accordingly.
Potential Applications
- Wireless communication systems
- Mobile devices with multiple antennas
- Network infrastructure equipment
Problems Solved
- Increased power consumption in multi-user multiple-input multiple-output (MU-MIMO) mode
- Resource waste in single-port transmission mode
Benefits
- Reduced power consumption
- Efficient utilization of resources
- Improved overall performance of wireless communication systems
Original Abstract Submitted
A multi-antenna operation mode indication method and an apparatus resolve a problem that increased power consumption and a resource waste are caused because a terminal device still operates in a multi-user multiple-input multiple-output (MU-MIMO) mode by default in a single-port transmission mode. The method includes: a network device sends indication information to a terminal device, to indicate that a multi-antenna operation mode of the terminal device is single-user multiple-input multiple-output (SU-MIMO) or MU-MIMO. The terminal device determines, based on the indication information from the network device, whether a demodulation reference signal (DMRS) port number corresponding to the terminal device and a DMRS port number not corresponding to the terminal device are allocated to another terminal device, to adjust the multi-antenna operation mode.
