ABSTRACT:
Techniques for reliable transmission of higher priority data within a frame are disclosed. In one aspect, an inner code is applied to one or more partial segments of a transmitted data frame in addition to any outer code applied to the entire frame. In another aspect, inner coded segments of a received frame are decoded when decoding of the outer code indicates one or more errors within the frame. The inner coded segment is retained when the inner decoding decodes without error. Various other aspects are also disclosed. These aspects have the benefits of reducing the number of retransmissions of higher priority data, as well as reducing delay for time-sensitive segments of the frame. The result is more efficient use of bandwidth, more responsiveness to higher priority segments, such as signaling traffic, and capacity, power, and other efficiencies associated therewith.
