METHOD AND APPARATUS FOR CALIBRATION IN DISTRIBUTED MIMO NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18330316 titled 'METHOD AND APPARATUS FOR CALIBRATION IN DISTRIBUTED MIMO NETWORKS
Simplified Explanation
The abstract describes a method for calibration in distributed multiple input multiple output (MIMO) networks. The method involves determining phase offsets for transmission of reference signals (RS) between base stations (BS) and user equipment (UE), based on received UL RS and feedback from the UE. The phase offsets are used to optimize DL data transmission between the BS and UE.
- The method involves receiving UL RS from a UE and determining a phase offset for DL RS transmission to the UE.
- The phase offset is determined based on the UL RS received from the UE and a second UL RS associated with a different BS.
- The DL RS is transmitted with the determined phase offset.
- UE feedback associated with the DL RS and the second DL RS is received.
- Based on the received feedback and the determined phase offset, a second phase offset is determined for DL data transmission between the first BS and the second BS.
Potential applications of this technology:
- Wireless communication networks: The method can be applied in wireless communication networks using distributed MIMO systems to improve the calibration and optimization of DL data transmission between base stations and user equipment.
Problems solved by this technology:
- Calibration in distributed MIMO networks: The method solves the problem of calibrating phase offsets for DL RS transmission in distributed MIMO networks, ensuring optimal DL data transmission between base stations and user equipment.
Benefits of this technology:
- Improved DL data transmission: By optimizing the phase offsets for DL RS transmission, the method improves the quality and efficiency of DL data transmission between base stations and user equipment in distributed MIMO networks.
- Enhanced network performance: The calibration method helps in achieving better network performance by reducing interference and optimizing the transmission parameters in distributed MIMO systems.
Original Abstract Submitted
Calibration in distributed multiple input multiple output (MIMO) networks. A method performed by a first base station (BS) includes receiving a first uplink (UL) reference signal (RS) and determining, based on the first UL RS and a second UL RS, a first phase offset for transmission of a first downlink (DL) RS to a user equipment (UE). The second UL RS is associated with a second BS. The first phase offset of the first DL RS is relative to a second DL RS associated with the second BS. The method further includes transmitting the first DL RS with the first phase offset; receiving UE feedback associated with the first DL RS and the second DL RS; and determining, based on the first phase offset and the received feedback, for a DL data transmission to the UE, a second phase offset between transmissions of the first BS and the second BS.
