Abstract: Certain aspects of the present disclosure relate to techniques selecting a core network. As described herein, a user equipment (UE) may receive an indication of services provided by a first core network (CN). The UE may take action to reselect from the first CN to a second CN to access a set of services not provided by the first core network. When a UE desires services not available on a currently-connected CN, the UE may transmit an establishment request message requesting the services desired.

Abstract: Techniques are described herein to communicate policy information and policy information requests between user equipments (UEs) and a core network using control plane signaling. In some examples, non-access stratum (NAS) messages may be used to communicate policy information requests from a UE to the core network. Similarly, NAS messages may be used to communicate up-to-date policy information from the core network to the UE. In some examples, the core network may include number of functions to manage the communication of policy information with the UE. In some examples where the UE is roaming away from its home network, the core network may engage in additional signaling to pass policy information to the UE.

Abstract: Aspects described herein relate to reporting user equipment (UE) activity period statistics. Statistics for a UE regarding a time the UE is in a connected mode or idle mode during one or more activity periods can be determined. From the statistics for the UE, it can also be determined whether the time the UE is in the connected mode in the one or more activity periods is less than a threshold. At least a portion of the statistics for the UE can be provided to an access network node where the time the UE is in the connected mode in a corresponding portion of the one or more activity periods is less than the threshold.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may operate in an extended connected discontinuous reception (eDRX) mode to increase energy efficiency and extend battery life. Control signaling may be used to initiate or support the extended sleep cycles associated with eDRX operation. In some cases, a system frame number (SFN) extension may be implemented to record frame cycles and differentiate SFNs that occur in a first frame cycle from SFNs that occur in a second frame cycle. Control techniques to support eDRX operation and maintain network synchronicity and compatibility may also be employed. In some examples, a wireless system may broadcast extended or dedicated system information updates to an eDRX capable device or devices. In some cases, devices may adjust the rate at which radio link monitoring (RLM) measurements are taken to timely determine radio link failures (RLFs) in conjunction with eDRX operation.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for prioritizing incompatible network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes sending a request to connect to a set of network slices, wherein the request comprises at least one priority associated with at least one network slice in the set of network slices, and receiving signaling indicating a set of allowed network slices in response to the request.

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. Another exemplary method, performed by a UE, generally includes determining at least one paging hyper-frame for monitoring for a paging signal from a base station (BS) 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, and monitoring for the paging signal in at least one subframe within a radio frame of the paging hyper-frame.

Abstract: Techniques are described for configuring wireless service for a user equipment (UE) in a wireless communications network in which the UE may be served over one or more of multiple available cells. Wireless service for the UE may be configured based on parameters associated with each of the multiple cells, such as, for example, a primary/secondary cell designation of a cell, whether the cell operates using a licensed or an unlicensed radio frequency spectrum band, a radio access technology associated with a cell, and/or an operating frequency band of a cell. Based on the parameters for each cell, one or more cell configurations for serving the UE may be provided. The cell configurations may identify, for example, a set of rules that control how much and/or what type of traffic is sent on different cells.

Abstract: Aspects described herein relate to obtaining provisioned credentials for wireless network services. It can be determined that credentials have not been configured for accessing a network. In this case, a provisioning server supported by the network for obtaining credentials is selected, and a request to establish a connection with the network is transmitted. The transmitted request can indicate the provisioning server.

Abstract: Methods, systems, and devices are described for facilitating Machine Type Communication in a wireless communications system. Link budget-limited MTC devices, may be supported. An MTC physical broadcast channel may be utilized for the Machine Type Communication. The MTC physical broadcast channel may be transmitted over one or more subframes different from a regular physical broadcast channel. The payload for the MTC physical broadcast channel may be reduced. The MTC physical broadcast channel may also be utilized to indicate the presence of paging and/or to indicate a change in system information. Some embodiments utilize one or more MTC-specific system information blocks. The MTC-specific system information blocks may combine and/or simplify multiple system information blocks. The location of the MTC system information blocks may be predetermined or information about their location may be transmitted over the MTC physical broadcast channel. An enhanced paging channel may be used to indicate system information updates.
