Unequal multipath protection of different frames within a superframe using different cyclic prefix lengths

摘要

Techniques for providing multipath protection of a portion of a frame classified as having a first importance level (e.g., critical) are provided. Different cyclic prefix lengths may be used, depending on whether a frame contains information deemed critical.

主权项

1. A method for protecting information transmitted in a wireless communication system, comprising:
identifying a first cyclic prefix length associated with header information classified with a first importance level; identifying a first data frame containing the header information classified with the first importance level; selecting the first cyclic prefix length for the first data frame based on a determination that the first data frame comprises the header information for at least the first data frame and a second data frame; applying a cyclic prefix of the first cyclic prefix length to each symbol of the first data frame; selecting a second cyclic prefix length for the second data frame based on a determination that the second data frame comprises information classified with a second importance level, the second importance level being less than the first importance level; and generating a superframe comprising at least the first data frame having a cyclic prefix of the first cyclic prefix length and the second data frame having a cyclic prefix of the second cyclic prefix length, wherein at least one step of the method is performed by a hardware component.
