Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) operating in an unlicensed radio frequency spectrum band may transmit autonomously (e.g., without a resource assignment) to a base station. For example, a base station may indicate a periodic resource allocation to the UE using radio resource control (RRC) messaging. The UE may then perform a listen-before talk (LBT) procedure and transmit physical uplink control channel (PUCCH) or other messages using the periodic resource allocation. Thus, the UE may transmit uplink messages without receiving an assignment of uplink resources from the base station. The UE may transmit identification and synchronization information in a scheduling request (SR) resource of the autonomous PUCCH. For example, the UE may indicate a start time and duration of an autonomous uplink transmit opportunity (TxOP) using resources designated for SR transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A base station within a wireless system may determine a measurement scheme or uplink mode and then transmit an indication of the scheme or uplink mode to an associated user equipment (UE). The base station may, for example, identify a set of hidden nodes for the UE and configure the UE for autonomous or grant-based uplink transmissions accordingly. The UE may identify a signal strength of neighboring nodes, which the UE may communicated to the base station for identification of hidden nodes. In some examples, the UE may be configured with an autonomous uplink, which may support unscheduled uplink communications, when a base station determines that operating in the autonomous uplink mode would provide a benefit for the UE—e.g., a benefit for UE operation in view of hidden nodes with which the UE may contend.

Abstract: Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

Abstract: Transmit power for an access point (106) is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals (102, 104) to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access point may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal (104) that is in active communication with another access point (108).

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support management of network-configured sensing bandwidths in a wireless communication system. In particular aspects, a network configures a sensing bandwidth, and the sensing bandwidth configuration is signaled to a contending node. The contending node (e.g., a UE or a base station) performs a medium sensing procedure (e.g., a listen-before-talk (LBT) procedure) using the signaled configuration of the sensing bandwidth. Aspects of this disclosure provide various techniques for signaling the configuration of the sensing bandwidth to the contending node.
