Abstract: Systems, methods, and apparatuses for detecting interference caused by a wireless local area network (WLAN) and a wireless wide area network (WWAN) node operating in an unlicensed or shared spectrum is disclosed. In accordance with the present disclosure, a base station may generate a null tone pattern for one or more subframes transmitted to the UE. The null tone pattern may include one or more null tones mapped to consecutive symbols in each resource block to detect interference. Accordingly, a UE may monitor a wireless channel from a base station for a null tone transmission. The UE may detect a null tone pattern by decoding a known physical layer channel to identify the null tone pattern. In some aspects, the UE may generate channel estimates, decode allocated resources, determine timing of future transmissions and/or establish communication with the base station based on the identified null tone pattern.

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: Sidelink based positioning of a user equipment (UE) using multiple sidelink UEs as anchor nodes is based on the synchronization status of available sidelink UEs. The synchronization reference of each available sidelink UE may be determined, for example, and sidelink UEs are selected for sidelink positioning based on their synchronization references. For example, sidelink UEs that have a common synchronization source and/or have higher synchronization priority level may be selected for sidelink positioning over other sidelink UEs. Additionally, the positioning method used for the sidelink positioning session may be selected based on the synchronization quality of each of the sidelink UEs. If each sidelink UE has a synchronization quality within a range, a time synchronization sensitive positioning method may be selected, but if one or more sidelink UEs have a synchronization quality outside the range, a positioning method that is less time synchronization sensitive may be selected.

Abstract: In some implementations, a first user equipment (UE) may send a first message comprising a quality of service (QoS) profile to a second UE. The QoS profile may include a response time requirement for providing positioning information within the positioning session. The first UE may receive a second message from the second UE, the second message comprising an indication of whether the second UE can meet the response time requirement. The first UE may determine resource pool parameters for the positioning session. The resource pool parameters may be based at least in part on the indication of whether the second UE can meet the response time requirement. The first UE may send a third message comprising the resource pool parameters to the second UE.

Abstract: Aspects presented herein may enable a UE to store multiple sets of UE processing capabilities at one or more entities, and to activate one of the stored sets based on the UE's current processing availabilities to improve positioning latency. In one aspect, a UE transmits, to at least one of a second UE, a base station, or a network entity, a plurality of capability sets associated with UE positioning processing, the plurality of capability sets including at least a first capability set corresponding to a first level of the UE positioning processing and a second capability set corresponding to a second level of the UE positioning processing, the first level being different from the second level. The UE transmits, to the at least one of the second UE, the base station, or the network entity, an indication to activate one of the plurality of capability sets for UE positioning.
