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: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit sets of network coding encoded packets user equipments (UEs), and each set of network coding encoded packets may be associated with a redundancy overhead. The base station may dynamically identify the redundancy overhead for transmitting sets of network coding encoded packets to each UE based on a failure rate associated with a previous transmission of network coding encoded packets to that UE. For example, the base station may determine a failure rate associated with a transmission of a first set of network coding encoded packets and may identify a redundancy overhead associated with one or more second sets of network coding encoded packets based on the determined failure rate. In some cases, the base station may identify different redundancy overheads for transmissions of network coding encoded packets to different UEs.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may determine an energy pattern corresponding to a characteristic of the first wireless device. The energy pattern may include at least two sub-periods of different energy levels. The first wireless device may transmit the energy pattern on a channel (e.g., an unlicensed channel) prior to transmitting a first message on the channel to indicate the upcoming message to other devices. A second wireless device may monitor the channel during energy detection intervals and may detect the energy pattern. The second wireless device may determine the characteristic of the first wireless device based on detecting the energy pattern and may modify timing for transmission of a second message on the channel based on determining the characteristic. The first wireless device may transmit the first message on the channel based on transmitting the energy pattern.
