Abstract: Aspects described herein relate to managing blind decoding of a control channel search space. A number of blind decodes configured for a control channel search space can be determined based at least in part on one or more parameters broadcasted by a access point that transmits a control channel in the control channel search space. One or more reduction values can be determined for the number of blind decodes at the UE. A pattern for performing a subset of the number of blind decodes can be determined based at least in part on the one or more reduction values. Blind decoding can be performed for the control channel based on the pattern for performing the subset of the number of blind decodes to obtain control data transmitted in the control channel.

Abstract: Various aspects related to techniques for harmonization between common reference signal (CRS) and demodulation reference signal (DM-RS) based transmission modes (TMs) in unlicensed spectrum are described. In one aspect, a downlink/uplink (DL/UL) subframe configuration may be signaled for each subframe. Information provided by the DL/UL subframe configuration may indicate whether the respective downlink subframe is a single-frequency network (MBSFN) subframe (associated with DM-RS-based TM) or a non-MBSFN subframe (associated with CRS-based TM). In another aspect, periodic as well as aperiodic channel state information (CSI) reporting requests may be supported. In yet another aspect, discontinued reception (DRX) wake ups for unlicensed carriers may be explicitly or implicitly indicated to a user equipment (UE) via a carrier in a licensed spectrum.
Abstract translation: 描述与非许可频谱中的公共参考信号（CRS）和基于解调参考信号（DM-RS）的传输模式（TM）之间的协调技术相关的各个方面。 在一个方面，可以为每个子帧发信号通知下行链路/上行链路（DL / UL）子帧配置。 由DL / UL子帧配置提供的信息可以指示相应的下行链路子帧是单频网络（MBSFN）子帧（与基于DM-RS的TM相关联）还是非MBSFN子帧（与基于CRS的TM相关联） 。 在另一方面，可以支持周期性和非周期性信道状态信息（CSI）报告请求。 在另一方面，可以通过许可频谱中的运营商向用户设备（UE）明确地或隐含地指示用于未授权载体的中断接收（DRX）唤醒。

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An eNB transmits an indicator for a frame identifying a DL transmission period. The indicator may comprise a frame format indicator identifying only a plurality of downlink subframes scheduled for a contention-based carrier. The eNB may transmit a second indicator for an UL transmission period and may grant a UE at least one UL subframe for UL transmission. The UE monitors for an UL grant and for a D-CUBS at either the end of the DL subframes or after an UL assignment. The eNB may transmit a provisional grant UL assignment for UL transmission on an SCC and respond with a grant confirmation in response to an SR granting the UE resources for UL data transmission.

Abstract: In the application of TDD and eIMTA to LTE in the unlicensed spectrum, various alterations may be needed to compensate for interference from and the behavior of RATs operating in this range of frequencies. Various UE and base station methods are presented, including modified TDD configurations and UE behaviors to advance operations on unlicensed spectrum. A method, an apparatus, and a computer-readable medium for wireless communication are provided whereby configuration information is conveyed to a UE for communicating on a carrier in the unlicensed spectrum. The configuration information indicates a subframe allocation for at least one frame on the unlicensed carrier. Other aspects are directed to the detection of the transmission, communication of new and modified eIMTA configuration transmissions, and mechanism and behaviors which address unreceived configuration information.

Abstract: In an aspect, a user equipment (UE) may receive at least one discontinuous reception (DRX) configuration, wherein the at least one DRX configuration indicates at least a DRX on-time and a wake-up signal monitoring window for reception of a wake-up signal, wherein the wake-up signal is configured for use in determining whether the UE is to wake-up for sidelink positioning operations. The UE may transition from a sleep state to a wake-up state during the DRX on-time to conduct one or more sidelink positioning operations dependent on whether the wake-up signal is received during the wake-up signal monitoring window.

Abstract: Aspects presented herein may enable a UE to communicate with NTN base station(s) more efficiently to improve NTN positioning. In one aspect, a UE communicates with at least one TN base station via a first set of PFLs for a UE positioning session. The UE communicates with at least one NTN base station via a second set of PFLs for the UE positioning session, the second set of PFLs being different from the first set of PFLs. In another aspect, a UE measures a first RS that is transmitted from a base station via a wide beam, the wide beam having a coverage over an area. The UE measures at least one second RS that is transmitted from the base station via at least one narrow beam based on the first RS being successfully decoded, each of the at least one narrow beam covering a portion of the area.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to determine a location of a device using carrier phase positioning. A process includes transmitting, at the device to a network entity, a phase measurement capability of a device (e.g., a user equipment (UE)) for subcarrier set pairs of different resources received by the device. The different resources are associated with a reference signal. The process can include receiving, at the device, a phase measurement request from a network entity for configuring phase measurements of the subcarrier set pairs of the different resources. The process can include transmitting a phase measurement report to the network entity based on the phase measurement request, the phase measurement report including information associated with a measured phase difference of at least one subcarrier set pair associated with the different resources.
