SUPPORT OF FREQUENCY OVERLAPPING CARRIERS Russian patent published in 2021 - IPC H04W16/14 

FIELD: wireless communication.

SUBSTANCE: invention relates to wireless communication and can be used to support frequency-overlapping carriers among the first radio access technology (RAT) and the second RAT, with the first RAT being New Radio (NR), and the second RAT being Long Term Evolution (LTE). The information of the second RAT is determined to be signaled to the wireless device of the first RAT. The second RAT information is configured to allow the wireless device of the first RAT to determine, at the resource element level, the resources reserved for transmissions of the second RAT, where the second RAT information also includes physical downlink shared channel bitmap templates for the second RAT, wherein the bitmap indicates radio resources to the wireless device to exclude NRs from the reserved resources. The second RAT is transmitted to the wireless device of the first RAT.

EFFECT: invention is aimed at improving efficiency in configuring reserved NR resources to support coexistence of coincident NR carriers with LTE.
