Abstract: A method for operating a first distributed unit (DU) includes participating in a link layer context transfer with a second DU, establishing a user data path for a mobile device, the user data path connecting the mobile device with a centralized unit (CU) including a radio control protocol entity communicating with the mobile device, and storing first user data for the mobile device received from the CU and second user data for the mobile device received from the second DU. The method includes establishing a connection with the mobile device, sending the first user data and the second user data to the mobile device, and adapting the link layer context to operate in the first DU for exchanging data between the CU and the mobile device, wherein adapting the link layer context includes associating an uppermost protocol layer of the first DU with a lowest protocol layer of the CU.

Abstract: Embodiments are provided herein for enabling buffer status reporting for Multi-stream aggregation (MSA) in wireless networks. In an embodiment, a user equipment (UE) receives from a network, a configuration regarding one of enabling and disabling cross-node buffer status reporting. The UE further receives a first uplink grant from a first network node, and obtains a buffer status intended for a second network node. Upon enabling cross-node buffer status reporting according to the configuration, the UE transmits, in the first uplink grant to the first network node, the buffer status intended for the second network node. The first network node receives, from the UE, the buffer status intended for the second network node, and determines whether to forward the buffer status to the second network node according to the configuration regarding buffer status forwarding previously received at the first network node.

Abstract: A single hybrid automatic repeat request (HARQ) entity can be associated with multiple serving units to achieve lower complexity user-side signal processing during multi-point communication. Additionally, configuring a single HARQ entity to establish HARQ operations with multiple serving units may achieve lower latency communication when users are engaging in multi-point communications, such as coordinated multi-point transmission/reception (CoMP). HARQ entity associations and/or reconfigurations can be achieved through radio resource control (RRC) signaling.

Abstract translation: 单个混合自动重传请求（HARQ）实体可以与多个服务单元相关联，以在多点通信期间实现较低复杂度的用户侧信号处理。 另外，当用户参与诸如协调的多点发送/接收（CoMP）等多点通信时，配置单个HARQ实体来建立具有多个服务单元的HARQ操作可以实现较低等待时间的通信。 可以通过无线电资源控制（RRC）信令来实现HARQ实体关联和/或重新配置。
