Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

Abstract: In a wireless communication system, user equipment (UE) has autonomy provided by one or more set of rules to handle processing during a measurement gap. UE can ignore or use only a portion of the whole measurement gap if not needed. Thereby, an urgent need for remaining tuned to source carrier frequency can be supported, such as utilizing Random Access Channel (RACH) procedure. UE can also choose to tune to a target carrier frequency supporting timely handovers. Depending on the type of processing required (download shared channel (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.

Abstract: Aspects of the disclosure relate to dual connectivity reporting. In one example, a dual connectivity communication is established, which includes a communication with a master node according to a first radio access technology (RAT), and a communication with a secondary node according to a second RAT. A change in measurement capability is then detected, and subsequently reported to the master node and/or secondary node. In another example, a scheduling entity establishes a first or second communication of a dual connectivity communication with a scheduled entity. The first communication is established according to a first RAT when operating as a master node, and the second communication is established according to a second RAT when operating as a secondary node. An indication is then received from the scheduled entity of a change in measurement capability, and the first and/or second communications are reconfigured in response to the change in measurement capability.

Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) capability indication that indicates one or more constraints associated with a supported modulation order. In some cases, the UE capability indication may indicate that the UE supports a particular modulation order, but has a capacity constraint such that an associated data rate is limited to a data rate associated with a lower modulation order. In some cases, one or more frequency bands may be mapped to a UE constraint.

The method further includes establishing a connection with the second base station.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a secondary component carrier (CC) for a user equipment (UE) which is not aligned on a valid channel raster entry. The location of the secondary CC may be indicated based on a reference location relative to another frequency or another CC. The reference location of the secondary CC may be the center of the new CC, an edge of the secondary CC, the position of a subcarrier within the secondary CC, or the position of a resource. In some examples, the reference location of the secondary CC may be indicated relative a currently used CC, an arbitrary channel entry, or an absolute frequency location. In some examples, the relative location may be provided in resource blocks or subcarriers and the subcarrier spacing (SCS). The base station may indicate the width of the secondary CC to the UE.

Abstract: The present disclosure provides a mechanism that may allow a UE to determine whether PBCH repetition is enabled in the target cell without performing a hypothesis test. For example, the apparatus may receive a handover message from a serving cell. In an aspect, the handover message may be associated with a handover procedure to a target cell. In addition, the apparatus may determine whether to perform a hypothesis test to determine if a PBCH repetition is enabled in the target cell based on the handover message. In one example, the apparatus may determine not to perform the hypothesis test when the handover message includes information that indicates if the PBCH repetition is enabled in the target cell. In another example, the apparatus may determine to perform the hypothesis test when the handover message does not include information that indicates if the PBCH repetition is enabled in the target cell.

The method includes receiving, at the user equipment from the base station, a message including at least one configuration parameter applicable to the plurality of secondary cells. The method further includes configuring the user equipment for the plurality of secondary cells based on the at least one configuration parameter.

Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station. In some aspects, the mobile device may scramble the information associated with signals and transmit the information associated with signals to the base station prior to establishing a security context for a connection between the mobile device and the base station.

The method includes transmitting a measurement report for the one or more secondary cells. The method includes receiving secondary cell activation information for the user equipment from the target base station prior to completion of connection of the user equipment to the target base station, wherein the secondary cell activation information indicates the one or more secondary cells. The method includes activating the one or more secondary cells at the user equipment after completion of connection to the target base station.

Abstract: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: The present disclosure provides user equipment power consumption and secondary cell (SCell) activation latency reductions in wireless communication systems. For example, a UE may determine that a secondary cell activation condition has been satisfied. The UE may further transition to a secondary cell activated state based on determining that the secondary cell activation condition has been satisfied, the secondary cell activate state corresponding to a dormant SCell state. The UE may operate at least in the dormant SCell state.

Abstract: Methods, systems, devices, and apparatuses are described for wireless communications in which a wireless device may identify a small cell (e.g., SCell) and establish an independent connection with the small cell based at least in part on selection parameters received from a macro cell (e.g., PCell). The selection parameters may include power and/or quality parameters, as wells as a set of candidate cells from which to make the selection. The macro and small cells may be in communication with each other but need not be associated with the same base station (i.e., are not collocated). Once the small cell connection is established, the device may communicate with both cells concurrently. Available uplink data and/or downlink data may trigger the need for the device to connect with the small cell. For example, the small cell connection may be used to communicate uplink/downlink data associated with certain quality-of-service (QoS) and/or bearer identifier.

Abstract: Systems and methodologies are described that facilitate notifying and detecting modification of system information in a wireless communication system. A mobile device may detect an inability to receive a paging message transmitted by a base station during a first time period, receive at least one system information block (SIB) transmitted by the base station during a second time period, and determine whether to receive one or more additional SIBs transmitted by the base station in the second time period based on information obtained from the at least one SIB received. The mobile device may detect an inability to receive a paging message upon entering a cell from being out of service or upon initial device starting up. The mobile device may determine whether to receive one or more additional SIBs by comparing a value tag of the at least one SIB received to a previously stored value tag.

Abstract: Aspects of the present disclosure provide techniques that may be used wireless network communication devices to support devices operating with extended discontinuous reception (eDRX). An exemplary method, performed by a BS, generally includes determining at least one paging hyper-frame for paging a user equipment (UE) based on an identification (ID) of the UE, the paging hyper-frame determined from a set of periodically occurring hyper-frames that each span a number of radio frames, receiving a request to page the UE, and transmitting a paging signal to the UE in at least one subframe within a radio frame of the paging hyper-frame.

Abstract: Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.
