Abstract: The disclosure provides for a method of interference detection using adaptive energy detection in unlicensed spectrum. The method can include a first modem operating according to a first radio access technology (RAT) receiving a message from a network entity operating according to the first RAT. The first modem sends a detected energy level value to a second modem that is using a second RAT, where the detected energy level value is based at least on the measured energy level of the received message. The second modem adjusts an energy detection threshold based on the detected energy level value received from the first modem. In an aspect, the first modem receives messages from a plurality of network entities operating according to the first RAT, where the detected energy level value is determined based on measured energy levels of the plurality of received messages.

Abstract: Techniques are provided for decoupling uplink and downlink operations. According to certain aspects, a wireless node (e.g., a low power node) may receive, from a base station of a first cell, signaling indicating a random access channel (RACH) configuration for a wireless device. The wireless node may then detect the wireless node performing a RACH detection (based on the RACH configuration) and report the RACH detection and desired UL configuration to the base station of the first cell. The base station of the first cell may then select the wireless node for serving the wireless device for UL operations (e.g., based on the reported RACH detection-and similar reports from other wireless nodes detecting the same RACH procedure).

Abstract: The present disclosure presents a method and an apparatus for transmitting discovery signaling from a base station. For example, the method may include encoding a wireless fidelity (Wi-Fi) beacon at the base station for transmission and transmitting the encoded Wi-Fi beacon from the base station to one or more neighboring wireless nodes. The Wi-Fi beacon is generated by a Wi-Fi access point (AP) co-located at the base station which is a long term evolution (LTE) or LTE advanced in unlicensed spectrum base station. As such, other wireless nodes can discover the LTE or LTE advanced in unlicensed spectrum base station.

Abstract: Certain aspects of the present disclosure provide techniques for controlling transmission power in shared radio frequency spectrum (SRFS). According to techniques, devices (e.g., BSs, UEs, etc.) transmitting in SRFS band may win contention to the SRFS band for at least a portion of a radio frame period. For example, the radio frame period may include a plurality of subframe periods. The devices may also transmit a first signal at a first transmit power during a first subframe period of the radio frame period and transmit a second signal at a second transmit power during a second subframe period of the radio frame period. For example, the first transmit power and second transmit power may be controlled based, at least in part, on a power level determined for the radio frame period.

Abstract: According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.

Abstract: The present disclosure provides methods and apparatuses for multi-carrier transmissions over adjacent channels that reduce self-jamming due to asymmetric interference. In an aspect, a large bandwidth load-base equipment (LBE) carrier may be provided such that CCA is performed jointly over the entire bandwidth. In another aspect, additional CCA timeslots may be used to synchronize the two carriers. In a further aspect, an extended CCA may be performed on a primary unlicensed carrier while a simple CCA may be performed on a secondary unlicensed carrier. In yet another aspect, LBE may be deployed on some carriers while frame-base equipment (FBE) may be deployed on other carriers.

Abstract: Aspects described herein relate to scheduling data for transmission over a plurality of component carriers. A base station can determine to increase bandwidth utilization over at least one component carrier of a plurality of component carriers assigned to a plurality of user equipments (UE). The base station can assign a plurality of resource blocks over the at least one component carrier to one or more fictitious UE identifiers and transmit data signals over the plurality of resource blocks to increase bandwidth utilization over the at least one component carrier. One or more network nodes may determine the one or more fictitious UE identifiers and may determine related resource assignment for canceling interference from data transmitted for the fictitious UE identifiers, performing channel estimation, etc.
