    摘要： The present application provides a method executed by user equipment (UE), comprising: receiving radio resource control (RRC) signaling, the RRC signaling comprising configuration information used for configuring, for the UE, a data radio bearer (DRB) supporting packet duplication; establishing a corresponding DRB according to the configuration information; and calculating transmittable data of a packet data convergence protocol (PDCP) entity for a logical channel corresponding to the established DRB. The present application also provides corresponding UE, a base station, and a corresponding method executed by a base station.

    摘要： The present disclosure provides a method performed by a Packet Data Convergence Protocol (PDCP) entity and the PDCP entity. The method comprises: mapping one or more PDCP Protocol Data Units (PDUs) received out-of-order from a lower layer entity of the PDCP entity to one or more PDCP Service Data Units (SDUs) and storing the PDCP SDUs in a reordering buffer; determining whether sequence numbers of one or more missing PDCP SDUs are smaller than the smaller one of the two maximum sequence numbers among PDCP SDUs received by the PDCP entity from two lower layer entities, respectively; and delivering one or more PDCP SDUs having sequence numbers smaller than the sequence numbers of the missing PDCP SDUs and one or more PDCP SDUs having sequence numbers larger than and consecutive with the sequence numbers of the missing PDCP SDUs, as stored in the reordering buffer, to a higher layer entity of the PDCP entity when the sequence numbers of the missing PDCP SDUs are smaller than the smaller of the maximum sequence numbers.

    摘要： The present application provides a method for establishing/reconfiguring a data hearer, comprising: receiving a request message for data bearer establishment/reconfiguration, wherein the request message comprises a data bearer identity used to identify a data bearer and a bearer type indication cell used to indicate a type of a to-be-established/reconfigured data bearer; and establishing/reconfiguring a corresponding data hearer according to the request message. The present application further provides user equipment and a base station for establishing/reconfiguring a data bearer.

    摘要： The present disclosure provides a mechanism allowing a PDCP transmitting entity to move a transmitting window even after a packet loss over an Xn interface. According to an embodiment, a timer is provided in the PDCP transmitting entity and is started when it is determined that a packet loss may occur. The transmitting window can be moved when the timer expires, regardless of whether a PDCP PDU corresponding to a lower limit of the transmitting window has been acknowledged to be successfully transmitted or not. According to a further embodiment, a PDCP receiving entity maintains a receiving window and a t-Reordering timer is used to assist the PDCP transmitting entity to move the transmitting window. In this way, even if a packet loss occurs over the Xn interface, the transmitting window can be moved to continue transmitting subsequent PDCP PDUs.

    摘要翻译： 本公开提供了允许PDCP发送实体即使在Xn接口上的分组丢失之后也移动发送窗口的机制。 根据实施例，在PDCP发送实体中提供定时器，并且当确定可能发生分组丢失时启动定时器。 当定时器到期时，可以移动发送窗口，而不管与发送窗口的下限对应的PDCP PDU是否已被确认成功发送。 根据另一实施例，PDCP接收实体维护接收窗口，并且使用t重排序定时器来辅助PDCP发送实体移动发送窗口。 以这种方式，即使在Xn接口上发生分组丢失，也可以移动发送窗口来继续发送后续的PDCP PDU。

    摘要： Provided in the present disclosure are user equipment and a method thereof, and a base station and a method thereof. A method performed by user equipment includes: receiving, from a base station, a medium access control control element (MAC CE) used to indicate an activation configuration of packet data convergence protocol (PDCP) duplication of a data radio bearer (DRB) and/or an associated radio link control (RLC) entity; and performing the activation configuration of the PDCP duplication and/or the associated RLC entity based on the MAC CE. Thus, the communication efficiency and reliability of a wireless communication system can be improved.
