Method and apparatus for transmitting and receving downlink control channel
First Claim
1. A method of receiving a downlink control channel at a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, first information related to a resource element group (REG) bundle size, and second information related to an interleaver size for interleaving REG bundles; and
receiving, based on the first information related to the REG bundle size and the second information related to the interleaver size, the downlink control channel over a control resource set (CORESET) that comprises a plurality of REGs that are bundled into one or more REG bundles according to the REG bundle size,wherein the one or more REG bundles are interleaved within the CORESET according to the interleaver size,wherein a duration of the CORESET is configured to be 1, 2, or 3 Orthogonal Frequency Division Multiplexed (OFDM) symbols,wherein the REG bundle size is related to the duration of the CORESET,wherein the second information related to the interleaver size relates to one of a number of rows or a number of columns of an interleaving matrix, andwherein the other of the number of rows or the number of columns of the interleaving matrix is determined based on (i) the one of the number of rows or the number of columns of the interleaving matrix and (ii) a number of REG bundles included in the CORESET.

Abstract
A method of receiving a downlink control channel at a user equipment (UE) in a wireless communication system is disclosed. The method includes receiving information on a resource element group (REG) bundle size and information on a size of a matrix for interleaving a plurality of REGs configuring at least one control channel element (CCE) through a higher layer, determining the matrix for interleaving the plurality of REGs based on the information on the size of the matrix and the information on the REG bundle size, interleaving the plurality of REGs bundled into one or more REG bundles according to the REG bundle size using the matrix, and receiving the downlink control channel based on the plurality of interleaved REGs.

10. A user equipment (UE) configured to receive a downlink control channel in a wireless communication system, the UE comprising:
-
a radio frequency (RF) module; at least one processor; and at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising; receiving, through the RF module and from a base station, (i) first information related to a resource element group (REG) bundle size, and (ii) second information related to an interleaver size for interleaving REG bundles; and receiving, through the RF module and based on the first information related to the REG bundle size and the second information related to the interleaver size, the downlink control channel over a control resource set (CORESET) that comprises a plurality of REGs that are bundled into one or more REG bundles according to the REG bundle size, wherein the one or more REG bundles are interleaved within the CORESET according to the interleaver size, wherein a duration of the CORESET is configured to be 1, 2, or 3 Orthogonal Frequency Division Multiplexed (OFDM) symbols, wherein the REG bundle size is related to the duration of the CORESET, wherein the second information related to the interleaver size relates to one of a number of rows or a number of columns of an interleaving matrix, and wherein the other of the number of rows or the number of columns of the interleaving matrix is determined based on (i) the one of the number of rows or the number of columns of the interleaving matrix and (ii) a number of REG bundles included in the CORESET. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
