Abstract
A method, applied to a UE, to mitigate interference for coexistence of OFDM-based radio access technologies, wherein the method includes receiving a dedicated RRC signal providing LTE CRS configuration information of neighboring LTE cells in one or more LTE carriers and providing the corresponding frequency location and bandwidth of the LTE carriers for an NR serving cell, wherein NR and LTE coexist in the same spectrum; determining the LTE CRS configuration and the corresponding frequency location of LTE CRS based on the received dedicated RRC signal; and performing LTE CRS interference suppression or cancellation in NR downlink (DL) transmission.
Claims11
A method, applied to a UE, to mitigate interference for coexistence of OFDM-based radio access technologies, comprising:
- receiving a dedicated radio resource control (RRC) signal providing Long Term Evolution (LTE) cell-specific reference signal (CRS) configuration information of neighboring LTE cells in one or more LTE carriers and providing corresponding frequency location and bandwidth of the LTE carriers for a New Radio (NR) serving cell, wherein NR and LTE coexist in the same spectrum;
- wherein the NR serving cell comprises a first base station, and the neighboring LTE cells comprises other base stations;
- wherein the first base station obtains the LTE CRS configuration from the other base stations;
- determining LTE CRS configuration and corresponding frequency location of LTE CRS based on the received dedicated RRC signal;
- and
- performing LTE CRS interference suppression or cancellation in NR downlink (DL) transmission.
