Claim Text:
1. A channel estimation method for estimating a data channel of a data resource element of a physical resource block (PRB) in a time-frequency domain, comprising: utilizing a detection circuit to perform a first PRB bundling detection in a first direction of the time-frequency domain to detect if at least one neighboring PRB is allowed to be bundled with the PRB, and accordingly generating a first PRB bundling detection result; determining a PRB processing range according to at least the first PRB bundling detection result, wherein the PRB processing range comprises a plurality of PRBs, and at least the PRB is included in the PRB processing range; and when the first PRB bundling detection result indicates that the at least one neighboring PRB is allowed to be bundled with the PRB, the at least one neighboring PRB is included in the PRB processing range, and when the first PRB bundling detection result indicates that the at least one neighboring PRB is not allowed to be bundled with the PRB, the at least one neighboring PRB is not included in the PRB processing range; obtaining a plurality of pilot channels for pilot resource elements in the PRB processing range; and estimating the data channel of the data resource element according to the pilot channels; wherein the first PRB bundling detection to detect if the at least one neighboring PRB is allowed to be bundled with the PRB comprises: obtaining PRB bundling reference information from the detection circuit; and comparing the PRB and the at least one neighboring PRB with the PRB bundling reference information, to determine whether the at least one neighboring PRB is bundled with the PRB.
