Abstract: This application provides a data transmission method and apparatus, to determine a TCI-state used for data transmission and correctly receive downlink data, thereby improving data transmission efficiency. The method includes: receiving downlink control information (DCI); and
if an offset between the DCI and a corresponding physical downlink shared channel (PDSCH) is less than a preset threshold, at least one transmission configuration indicator (TCI) states configured for a serving cell of scheduled PDSCH comprises quasi-co-location (QCL-TypeD) information, and at least one TCI codepoint indicates two TCI states, receiving the corresponding PDSCH by using two default TCI-states corresponding to a smallest codepoint among TCI codepoints indicating two different TCI-states.-

Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for handover processing. The method includes: receiving a handover request sent by a UE for handover to a micro base station; and sending instruction information to the UE according to a preset rule and the handover request, so as to instruct the UE to send start information, where the start information is used to instruct the micro base station to start an interference coordination mode used to enable the micro base station to mute preset time-frequency resources and corresponding to the start information. This prevents formation of a victim UE and greatly mitigates impacts caused by a coverage hole.
Abstract translation: 本发明的实施例提供了一种用于切换处理的方法，装置和系统。 该方法包括：接收由UE发送的用于切换到微基站的切换请求; 并根据预设规则和切换请求向UE发送指令信息，以指示UE发送开始信息，其中开始信息用于指示微基站开始干扰协调模式，以使能 微基站静音预设时频资源，并对应起始信息。 这样可以防止受害者UE的形成，并大大减轻覆盖孔造成的影响。

Abstract: A demodulation reference signal (DMRS) indicating method, a DMRS receiving method, and an apparatus are described. A transmit end determines, from a plurality of groups of demodulation reference signal DMRS configuration information, DMRS configuration information corresponding to a current DMRS transmission scheme. The transmit end obtains DMRS indication information based on the DMRS configuration information, where each group of DMRS configuration information includes a plurality of pieces of DMRSs configuration information. The transmit end sends the DMRS indication information. The described method and the apparatus are implemented to match a plurality of New Radio (NR) scenarios. The described operations can satisfy a requirement for transmitting more layers of data and reduce indication overheads.
