Abstract: Methods, systems, and devices are described for a clear channel assessment (CCA) procedure in a long term evolution (LTE) controlled Wi-Fi (LTE-CW) system. A user equipment (UE) may receive a resource grant that identifies a plurality of channels of a shared frequency spectrum subband available for uplink communications. The UE may identify a primary channel associated with a neighboring Wi-Fi basic subscriber set (BSS) and determine whether the primary channel is within the plurality of channels. The UE may select a channel of the plurality of channels based on the determining. The UE may perform a signal detect CCA procedure on the selected channel.

Abstract: Methods, systems, and devices for wireless communication are described. A first device in a synchronous network performs a first clear channel assessment (CCA) procedure on a channel; identifies the channel as being available based at least in part on the first CCA procedure; and transmits a packet on the channel immediately following the completion of the first CCA procedure. A second device performs a CCA procedure on the channel using the same count-down duration if the first and second devices are associated with the same first operator. If the first and second devices are associated with different operators, the second device performs a second CCA procedure on the channel having a different count-down duration than the count-down duration of the first CCA procedure.

Abstract: Methods, systems, devices, and apparatuses are described for a listen-before-talk (LBT) mechanism. A wireless node, e.g., a base station, may determine that a channel is available based on completing a clear channel assessment (CCA) procedure. The wireless node may be associated with a first operator. The wireless node may transmit a first message on the channel in a subframe based on the CCA procedure. The first message may include a header portion that precedes a data portion. The first message may be time aligned with a second message transmitted from a second wireless node that is associated with the first operator.

Abstract: Methods, systems, and devices are described for wireless communication. A transmitter may receive feedback that a station failed to decode a packet sent over a first channel, and the transmitter may determine to re-send the packet or to send parity bits over the first channel or over a second channel to assist in decoding the failed packet. The first channel may be in an unlicensed radio frequency spectrum, and the second channel may be in a licensed radio frequency spectrum and may have a higher reliability level compared to the first channel. The transmitter may determine a first channel degradation level, which may be based on a signal-to-noise ratio received from the station, and may determine an amount of parity bits to send based on the degradation. The transmitter may determine the reliability level of each channel, which may be based on a channel quality indicator.

Abstract: Methods, systems, and devices are described for adapting access timing parameters when using DSRC spectrum. A multi-mode device may adapt at least one access timing parameter while operating within the DSRC spectrum. The at least one access timing parameter may be adapted to provide priority to transmissions of DSRC devices using the DSRC spectrum. The multi-mode device may increase a duration of a short inter-frame spacing (SIFS) to be at least equal to a duration of a SIFS used by a DSRC device.

Abstract: A system and method are disclosed that may provide an accurate estimate of the angle of arrival (AoA) of a wireless signal received by a device. The received wireless signal may include a plurality of signal components associated with a number of different arrival paths.
