In some aspects, bundling may involve sending information sent over multiple carriers (e.g., information sent from or to multiple cells) where the information sent over the carriers is combinable at a receiver. For example, a communication device may send the same set of information (e.g., transport blocks with the same content) via multiple carriers, send different redundancy versions of a set of information via different carriers, send information via different beams on different carriers, or send information using a combination of these techniques. The disclosure relates in some aspects to indicating whether bundling is applied across carriers. For example, downlink control information (DCI) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all or a subset of the scheduled carriers. ## Claims ### Claim 1 A method of communication for a wireless communication device, comprising: receiving downlink control information (DCI), wherein the DCI comprises a first indication that first information scheduled for transmission on a first carrier of a plurality of carriers is a duplication of or combinable with second information scheduled for transmission on a second carrier of the plurality of carriers; receiving the first information via the first carrier; receiving the second information via the second carrier; and combining the first information and the second information according to the first indication. ### Claim at position 2 2-15.
