Abstract: Systems and methodologies are described that facilitate mitigating effect of non-linear distortion from a power amplifier on a spectral mask margin. Power limit indications can be analyzed in scheduling mobile devices. Mobile devices with power limits can be scheduled on inner subbands. The power limits can be based at least in part on power amplifier headroom information. Other mobile devices can employ remaining portions of an allocated spectrum. Further, mobile devices can evaluate and establish a power amplifier backoff based upon the subband scheduling.

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 access terminal radio link monitoring on a shared communication medium are disclosed. In an aspect, an access terminal detects a missed reference signal event associated with a radio link established on the shared communication medium, wherein detecting the missed reference signal event comprises determining that the access terminal did not detect a reference signal for measuring a quality of the radio link transmitted during a reference signal configuration window, assigns an error metric to the missed reference signal event based on reference signal monitoring capabilities of the access terminal, and triggers a radio link failure based on the assigned error metric. In an aspect, the missed reference signal event may be a missed Discovery Reference Signaling (DRS) event, the error metric may be a Block Error Rate (BLER) weight, and the reference signal for measuring the quality of the radio link comprises a Cell-specific Reference Signal (CRS).

Abstract: Techniques for communication are disclosed. A method may include selecting from a subframe two or more resource elements for control signaling, wherein the subframe includes a plurality of symbol periods and each symbol period includes a plurality of resource elements, wherein the selected two or more resource elements are associated with a concurrent symbol period, and transmitting a resource allocation message to an access terminal, wherein the resource allocation message indicates that the selected two or more resource elements are allocated for control 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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an uplink grant that conveys an indication of a multi-transmission opportunity (TxOP) grant. The UE may transmit, during a first TxOP, a first uplink transmission in one or more subframes in accordance with the multi-TxOP grant. The UE may transmit, during a second TxOP, a second uplink transmission in one or more subframes in accordance with the multi-TxOP grant.
