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 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.

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.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for cell DTX (Discontinuous Transmission) scheduling. A Base Station (BS) determines an operational schedule for the BS including at least one ON period and at least one OFF period, wherein the BS provides a reduced level of service during the at least one OFF period relative to the at least one ON period. The BS transmits the determined operational schedule. A User Equipment (UE) receives the BS's operational schedule and determines, based on the BS's operational schedule and its own operational schedule also including ON and OFF periods, whether to perform at least one service associated with the BS.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment may receive an indication of a pre-paging signal configuration for reception of a pre-paging signal associated with a first cell. The UE may monitor for the pre-paging signal from the first cell in response to one or more conditions being satisfied, the one or more conditions based at least in part on the pre-paging signal configuration. In some examples, the UE may receive, based on the monitoring, the pre-paging signal from the first cell, and the UE may output an alert message associated with receiving the pre-paging signal, the alert message indicating for the UE to be relocated to improve coverage.

Abstract: Aspects for enabling Multiple-Input-Multiple-Output (MIMO) communications using a plurality of transmitters across at least two supported frequency bands are disclosed. The apparatus may be a user equipment (UE) that includes, for each UE-supported frequency band, a plurality of transmitters capable when configured of coherently transmitting the received information over the frequency band with information to be transmitted to a base station. The apparatus can identify MIMO coherence capability information for the supported frequency bands on a per-band and a per-band combination basis. The apparatus may determine a proposed transmission configuration based on the MIMO capability information and may report, to the base station, the proposed transmission configuration.
