    Abstract: Aspects of the present disclosure provide using pilot sequences that are better suited to hardware capabilities of a receiver, in particular the capabilities of an analog to digital converter (ADC). When the pilot sequence changes, in amplitude or phase, the received pilot symbols may be quantized to different quantization regions. By utilizing a particular pilot sequence, it may be possible to extract additional information from the pilot sequence being quantized over multiple quantization regions instead of only a single quantization region. Therefore, by careful selection of the pilot sequence taking into consideration capabilities of the receiver, it may be possible to obtain more accurate channel estimations.

    Abstract: Embodiments of the present invention provide a systematic solution to virtual random access (VRA) that dynamically and adaptively forms various metrics. The present invention facilitates dynamic data pipelining between the network-side and the UE-sides without the need to use the same cell-association concept as current wireless networks and provides soft associations between dynamic groups of UEs and TPs based on various UE, TP, and network related metrics. To provide efficient collaborative grouping and association among TPs and UEs, the present invention features a soft TP-UE association map based on several factors, such as individual UE metrics, TP metrics, effects of neighboring or nearby UEs (e.g., interference), and historical network knowledge.

    Abstract translation: 本发明的实施例提供了动态地和自适应地形成各种度量的虚拟随机访问（VRA）的系统解决方案。 本发明有助于网络侧和UE侧之间的动态数据流水线化，而不需要使用与当前无线网络相同的小区关联概念，并且基于各种UE，TP和TP提供动态组的UE和TP之间的软关联， 和网络相关的指标。 为了在TP和UE之间提供有效的协作分组和关联，本发明基于诸如个体UE度量，TP度量，邻近UE或附近UE的影响（例如干扰）等几个因素的特征在于软TP-UE关联映射，以及 历史网络知识。

    Abstract: This application provides a channel measurement method and apparatus. The method includes: A terminal device obtains a first reference signal set and a second reference signal set, where the first reference signal set includes N first reference signals, the second reference signal set includes M second reference signals, and M and N are positive integers greater than or equal to 1. The terminal device may further perform channel measurement based on the first reference signal set to obtain first channel information, where a first dimension of the first channel information is less than a quantity of transmit antennas of a first device. The terminal device may further obtain second channel information based on the second reference signal set and the first channel information, where a first dimension of the second channel information is less than the quantity of transmit antennas of the first device.

    Abstract: Aspects of the present disclosure provide methods and devices that facilitate two-way redirection via a reconfigurable intelligent surface (RIS) when beam correspondence does not hold. A first embodiment includes using a wide-beam redirection via RIS in which the RIS is configured to redirect the beam incident on the RIS in either direction such that the redirected beam can encompass the deviation of the redirected direction and still reach the destination. A second embodiment includes partitioning the RIS, or using multiple different RISs, where each part, or different RIS, is configured for each direction of communication. A third embodiment includes using time division-duplexing (TDD) such that the RIS is configured to transmit in one direction at a time.
