CROSS LINK INTERFERENCE MITIGATION IN FULL-DUPLEX NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17887316 titled 'CROSS LINK INTERFERENCE MITIGATION IN FULL-DUPLEX NETWORKS

Simplified Explanation

Methods, systems, and devices for wireless communications are described in the patent application. The system supports cross link interference (CLI) mitigation in full-duplex operations.

  • First user equipment (UE) encodes and precodes a message in two portions using different modulation and coding schemes (MCS) and precoding matrices.
  • The first precoding matrix is based on the communication link between the first UE and a network entity.
  • The second precoding matrix is based on the communication link between the first UE and a second UE.
  • The first UE transmits the message portions using beams associated with the respective precoding matrices.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support cross link interference (CLI) mitigation in full-duplex operations. For example, a first user equipment (UE) may encode and precode a first portion of a message according to a first modulation and coding scheme (MCS) and a first precoding matrix and a second portion of the message according to a second MCS and a second precoding matrix. The first precoding matrix may be based on a first communication link between the first UE and a network entity and the second precoding matrix may be based on the first communication link and a second communication link between the first UE and a second UE. The first UE may transmit the first portion of the message and the second portion of the message via beams associated with respective precoding matrices.
