Method and apparatus for control and data information resource mapping in wireless cellular communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a radio resource control (RRC) message configuring a first rate matching pattern and a second rate matching pattern, wherein the first rate matching pattern corresponds to first frequency resource information and first time resource information, and wherein the second rate matching pattern corresponds to second frequency resource information and second time resource information;
• transmitting, to the terminal, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH), the DCI including 2-bit information associated with rate matching;
• and
• transmitting, to the terminal, downlink data on the PDSCH based on the DCI,
• wherein a first bit of the 2-bit information corresponds to the first rate matching pattern and a second bit of the 2-bit information corresponds to the second rate matching pattern,
• wherein the first bit of the 2-bit information indicates whether the first rate matching pattern is not available for the PDSCH and the second bit of the 2-bit information indicates whether the second rate matching pattern is not available for the PDSCH,
• wherein in case that the 2-bit information indicates the first rate matching pattern and the second rate matching pattern are not available for the PDSCH, a union of resources not available for the PDSCH is formed by the first rate matching pattern and the second rate matching pattern, based on the 2-bit information, and the downlink data is not mapped on the union of resources, and
• wherein the first frequency resource information and the first time resource information for the first rate matching pattern or the second frequency resource information and the second time resource information for the second rate matching pattern is determined based on frequency resource information and time resource information associated with a physical downlink control channel (PDCCH) resource respectively.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• at least one processor coupled with the transceiver and configured to:
• receive, from a base station, a radio resource control (RRC) message configuring a first rate matching pattern and a second rate matching pattern, wherein the first rate matching pattern corresponds to first frequency resource information and first time resource information, and wherein the second rate matching pattern corresponds to second frequency resource information and second time resource information,
• receive, from the base station, downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH), the DCI including 2-bit information associated with rate matching, and
• receive, from the base station, downlink data on the PDSCH based on the DCI, wherein a first bit of the 2-bit information corresponds to the first rate matching pattern and a second bit of the 2-bit information corresponds to the second rate matching pattern,
• wherein the first bit of the 2-bit information indicates whether a the first rate matching pattern is not available for the PDSCH and the second bit of the 2-bit information indicates whether the second rate matching pattern is not available for the PDSCH,
• wherein in case that the 2-bit information indicates the first rate matching pattern and the second rate matching pattern are not available for the PDSCH, a union of resources not available for the PDSCH is formed by the first rate matching pattern and the second rate matching pattern, based on the 2-bit information, and the downlink data is not mapped on the union of resources, and
• wherein the first frequency resource information and the first time resource information for the first rate matching pattern or the second frequency resource information and the second time resource information for the second rate matching pattern is determined based on frequency resource information and time resource information associated with a physical downlink control channel (PDCCH) resource respectively.
