Contention-based co-existence on a shared communication medium
First Claim
Patent Images
1. A communication method, comprising:
- receiving information over a communication medium in accordance with a Time Division Duplexing (TDD) frame structure defining a series of frames and subframes;
determining a set of subframe resources within a subframe for carrying an acknowledgment channel over the communication medium, wherein the determined set of subframe resources occupies no more than a threshold fraction of the subframe and is spread in frequency over one or more interleaved blocks of OFDM tones; and
transmitting one or more acknowledgment messages associated with the received information over the acknowledgment channel via the determined set of subframe resources.

Abstract
Techniques for managing contention on a shared communication medium are disclosed. Various techniques are provided to facilitate aspects such as reference signaling, downlink medium access, uplink medium access, resource reuse, channel structures, acknowledgment schemes, fairness, acquisition, random access, paging, mobility, inter-operator mitigation, and so on for a frame structure implemented on the shared communication medium.
