Abstract: Techniques for intra- and inter-operator coordination on a shared communication medium are disclosed. A central coordination server may send an operating mode information message to coordinate operation of different points on the communication medium. An access point may receive such an operating mode information message and adjust one or more communication parameters. An access point may determine a level of timing synchronization with neighboring access points and send a synchronization advertisement message to an access terminal. An access terminal may receive a synchronization advertisement message and perform one or more measurements of the neighboring access points.

Abstract: Techniques for broadcast channel management on a shared communication medium are disclosed. An access terminal may be configured to identify a subframe number associated with a given subframe based not only on a subframe number indicator but also a reference boundary. Conversely, an access point may be configured to set a subframe number indicator for a given subframe based not only on its subframe number but also a reference boundary.

Abstract: Techniques for random access channel signaling on a shared communication medium are disclosed. A broadcast message including information associated with a Physical Random Access Channel (PRACH) may be transmitted and received on one or more subframes in a portion configured for downlink signaling. The broadcast message may comprise a contention type indicator, a timing advance indicator, or a combination thereof. The contention type indicator may indicate whether contention is in effect for transmission on the PRACH. The timing advance indicator may indicate whether an uplink transmission offset is in effect for transmission on the PRACH. Signaling over the PRACH may be transmitted and received on one or more subframes in a portion configured for uplink signaling.

Abstract: Techniques for control channel signaling on a shared communication medium are disclosed. An access point or an access terminal may communicate over a communication medium in accordance with a Time Division Duplex (TDD) frame structure defining a set of subframes that each span a plurality of time-domain symbol periods. The access point may transmit and the access terminal may receive control information via a short Physical Uplink Control Channel (sPUCCH) on one or more of the subframes in a portion of the subframe configured for uplink signaling. The sPUCCH may comprise one or more pilot symbols and one or more payload symbols that collectively occupy a subset of less than all of the symbol periods in each of the one or more subframes.

Abstract: Techniques for indicating and determining a subframe timing of an access point on a shared communication medium are disclosed. A method of transmitting a discovery reference signal (DRS) may include establishing a transmission timing for transmission of the DRS relative to a system timing of an access point, determining whether to transmit the DRS during a particular SF based on the selected DRS transmission window, and transmitting the DRS to at least one access terminal during the particular SF in response to a determination to transmit the DRS.
