Samsung patents method to reduce signal interference in 5G networks

Samsung has been granted a patent for a technique in distributed MIMO systems that manages how base stations handle different types of user traffic. The system identifies which devices are using joint transmission and adjusts signal strength offsets to minimize interference between them and other users.

Why it mattersThis improves the efficiency of wireless networks by better managing signal overlap, which could lead to more stable connections for users in dense areas.

In the filing’s own words

Methods and apparatuses for a joint transmission in a distributed MIMO in wireless communication systems. The methods of BS comprise: identifying a type of UEs comprising a JT UE and a non-joint traffic non-JT UE; receiving, from the JT UE, feedback information for determining an SINR offset; identifying RBs for a C-JT, the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource; determining whether to transmit the non-JT traffic on the RBs; determining the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs; and performing an interference mitigation operation between JT UEs and non-JT UEs.

What exactly they claim (claim 1)

1. A base station (BS) in a wireless communication system, the BS comprising: a processor configured to identify a type of user equipments (UEs) comprising a joint traffic (JT) UE and a non-joint traffic (non-JT) UE; and a transceiver operably coupled to the processor, the transceiver configured to receive, from the JT UE, feedback information for determining a signal-to-interference noise ratio (SINR) offset, wherein the processor is further configured to: identify resource blocks (RBs) for a coherent joint transmission (C-JT), the RBs being designated for non-JT traffic and comprising at least one of a time domain resource or a frequency domain resource, determine whether to transmit the non-JT traffic on the RBs, determine the SINR offset for the non-JT UE based on a determination whether to transmit the non-JT traffic on the RBs, and perform an interference mitigation operation between JT UEs and non-JT UEs.
