Abstract: Techniques for channel selection and related operations in a shared spectrum environment are disclosed. In one example, a channel selector or the like may be used to select one of a number of available channels as an operating channel based on a comparison of cost functions for each of the available channels, with the cost functions being based on separate utility and penalty metrics. In another example, a channel scanner or the like may be used to trigger a channel scan in response to a channel quality metric indicating poor service for a threshold number or proportion of access terminals. In another example, an operating mode controller may be used to trigger a Time Division Multiplexing (TDM) mode on an operating channel in response to a utilization metric being above a threshold. The TDM mode may cycle operation between activated and deactivated periods in accordance with a TDM communication pattern.

Abstract: Systems and methods for Discontinuous Reception (DRX)-aware Carrier Sense Adaptive Transmission (CSAT) communication in shared spectrum are disclosed. An access point, for example, may receive signals via a medium in accordance with a first RAT, and identify utilization of the medium associated with the first RAT based on the received signals. Based on the identified utilization of the medium, operation of a second RAT may be cycled between activated and deactivated periods of transmission over the medium in accordance with a Time Division Multiplexing (TDM) communication pattern. A Medium Access Control (MAC) Control Element (CE) may be transmitted to an access terminal associated with the second RAT to activate or deactivate the access terminal in accordance with the TDM communication pattern. The timing of the MAC CE transmission may be based on the TDM communication pattern and a DRX pattern associated with the access terminal.

Abstract: To enable coexistence in unlicensed bands or other shared spectrum, operators that deploy cellular coverage in unlicensed bands can broadcast and receive over-the-air (OTA) signaling messages that carry coexistence information such that the operators can adjust one or more parameters used to provide the cellular coverage in the unlicensed bands and thereby enable inter-operator coexistence. For example, the operators may coordinate the particular OTA signaling configuration used to carry the coexistence information and thereby enable each operator to learn information that the other operator(s) are using and thereby reduce interference on time, frequency, and/or spatial resources that may be shared among the operators providing the cellular coverage in the unlicensed bands. Furthermore, a user equipment (UE) that receives and decodes the OTA signaling messages exchanged among the operators may adjust one or more measurement parameters and/or operating parameters according to the coexistence information carried in the OTA signaling messages.

Abstract: The disclosure relates to reducing Wi-Fi interference from small cells that provide cellular coverage in unlicensed bands. In particular, in response to determining that a small cell is substantially unloaded (e.g., has traffic below a threshold), the small cell may be switched to a reduced interference configuration. For example, the small cell may be switched to a low downlink configuration to reduce interference in a time domain and/or a low bandwidth configuration to reduce interference in a frequency domain. Alternatively (or additionally), the small cell and/or any other small cells that have traffic below the threshold may switch to the same frequency and/or channel number to concentrate all possible interference on the same frequency and/or channel number. Further still, the configuration may be switched in a power domain, where a transmit power associated with the small cell may be adapted based on cellular measurements in combination with Wi-Fi measurements.

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.
