Claim of US Patent No. 11,071,124


1. A method for receiving data, the method performed by a wireless apparatus and comprising:receiving, from a serving cell supporting new radio access technology (NR), information related to cell-specific reference signal (CRS) of a long term evolution (LTE) cell, which includes information related to a CRS antenna port for the CRS of the LTE cell and information related to a v-shift value for the CRS of the LTE cell, based on the wireless apparatus supporting the NR;
determining resource elements (REs) used for the CRS of the LTE cell based on the information related to the CRS of the LTE cell; and
receiving, from the serving cell supporting the NR, the data, which is related to the NR,
wherein the data is not mapped in the REs that are used for the CRS of the LTE cell,
wherein the data is received based on an assumption that the data is rate-matched in one or more REs except for the REs used for the CRS of the LTE cell, and
wherein the data is rate-matched in the one or more REs except for the REs used for the CRS of the LTE cell, based on that a subcarrier spacing for the data, which is related to the NR, is 15 kHz.
