Rate-matching a data transmission around resources
Apparatuses, methods, and systems are disclosed for rate-matching a data transmission around resources. One method includes: receiving a downlink control channel (“DCC”) transmission in a predetermined time period; determining a first DCC candidate (“DCCC”) based on the downlink control channel transmission; determining whether the first DCCC belongs to a plurality of DCCCs associated with the DCC transmission, wherein the plurality of DCCCs carry the same downlink control information (“DCI”); in response to determining that the first DCCC belongs to the plurality of DCCCs: determining a second DCCC; and determining the DCI by decoding the first and the second DCCCs; in response to determining that the first DCCC does not belong to the plurality of DCCCs: determining the DCI by decoding the first DCCC; and determining downlink resources corresponding to a data transmission; and rate-matching the data transmission.
