Abstract: Techniques are provided for adaptively changing a periodicity of measuring signal characteristics for a UE in a relatively high speed environment based on one or more signal characteristics being outside of a threshold. Periodicity of measuring signal characteristics may be made directly by changing an interval at which measurements are taken. In certain examples, periodicity of measuring signal characteristics may be made indirectly by changing the length of a discontinuous reception (DRX) cycle. Some techniques provide one or more radio link monitoring (RLM) parameters may be modified based on a determination that a UE is in a high speed environment or measured signal characteristics are outside of a threshold.

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 translation: 描述了用于无线通信的无线通信的方法，系统，设备和装置，其中无线设备可以至少部分地基于从宏小区接收的选择参数来识别小小区（例如，SCell）并建立与小小区的独立连接 （例如，PCell）。 选择参数可以包括功率和/或质量参数，如作为进行选择的候选单元的集合的孔。 宏小区和小小区可以彼此通信，但不需要与相同的基站相关联（即，不并置）。 一旦建立小单元连接，设备可以同时与两个单元进行通信。 可用的上行链路数据和/或下行链路数据可以触发设备与小小区连接的需要。 例如，小单元连接可以用于传送与某些服务质量（QoS）和/或承载标识符相关联的上行链路/下行链路数据。

Abstract: Certain aspects of the present disclosure provide techniques for signaling and scheduling to enable network configured small gaps in intra-band inter-frequency measurement. A method that may be performed by a user equipment (UE) includes receiving, from a serving cell operating on a first frequency, an indication that synchronization signal block (SSB) indexes of a target cell operating on a second frequency can be derived from timing of the serving cell; and deriving an SSB index of the target cell, based on the timing of the serving cell.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a calibration to improve the accuracy, reliability, or both of signal transmissions. The UE may determine timing for the calibration procedure based on a received identifier for the UE (e.g., a radio network temporary identifier (RNTI), such as a cell RNTI (C-RNTI)). For example, the UE may determine a calibration offset between a reference time and a calibration gap according to an equation using at least the identifier as input. During the calibration gap, the UE may transmit a calibration signal using one or more antenna ports and may calibrate (e.g., adjust power amplification for) the one or more antenna ports based on an estimated actual transmit power for the calibration signal (e.g., received by other antenna ports of the UE or received by another device).

Abstract: A configuration to enable a UE to switch beams of respective CCs based on certain factors (e.g., RTD or TCI states), and not switch the beams simultaneously. The apparatus receives, from a base station, a transmission including an indication to change at least one of a TCI state for multiple CCs, a spatial relation for the multiple CCs, or a PL RS for the multiple CCs. The apparatus switches beams in response to the transmission, where timing of the switching is based on a grouping of the multiple CCs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, and a base station may receive, a report that includes information related to a power headroom available to the UE at a current power level and information related to a duty cycle that the UE can sustain over a moving integration window based at least in part on a maximum permissible exposure limit. In some aspects, the base station may transmit, and the UE may receive, scheduling information based at least in part on the information related to the power headroom available to the UE at the current power level and the information related to the duty cycle that the UE can sustain over the moving integration window. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a channel raster associated with a plurality of resource blocks of a channel. The plurality of resource blocks may have an asymmetric relation with respect to the channel raster. The base station may configure, based at least in part on the asymmetric relation, a message to indicate a resource block offset metric that comprises an indication of the channel raster and location information associated with a first resource block of the plurality of resource blocks. The base station may transmit the message to convey the indication of the resource block offset metric.

Abstract: Systems, methods, apparatuses, and computer-readable storage media for communicating a base station signal, such as a data signal, a control signal, or both, from a base station to a user equipment (UE) during a measurement window. In some aspects, the UE signals its availability corresponding to a measurement window to a serving base station. In some aspects, the UE signals a guard period associated with the measurement window to the serving base station. In other aspects, the serving base station signals a guard period to the UE.
