AI Technical Summary
Technical Problem
RedCap UE's limited capabilities lead to coverage loss. During repeated transmissions, the terminal channel state changes rapidly, and the existing 5G NR system's beam management cannot effectively match the dynamic channel, resulting in high latency and low transmission efficiency.
Method used
Dynamic beamforming is performed during repeated transmissions in the downlink channel. Different receive and transmit beams are indicated by beam configuration information to ensure that the beam matching the channel is used during the repeated transmission period.
Benefits of technology
It reduces latency and improves transmission efficiency, making it especially suitable for highly mobile terminals such as wearable devices.

Abstract
本公开是关于一种波束确定方法及装置、存储介质。波束确定方法应用于网络设备，包括：确定波束配置信息，其中，所述波束配置信息至少包括用于指示下行信道的N次重复传输中的至少一次重复传输对应的接收波束的参数，其中，N是自然数；通过与所述下行信道的N次重复传输中的至少一次重复传输对应的波束参数，确定发送所述N次重复传输中的至少一次重复传输对应的发送波束。即使在采用重复发送和重复接收以增强覆盖时，也能在下行信道的重复发送和重复接收的时间段内使用与信道匹配的发送波束和接收波束，由此降低时延，提高传输效率。
