摘要： A wireless communication method is described for managing packet data convergence protocol (PDCP) service data unit (SDU). The method can include receiving, at a first protocol layer of a first communication device, a first service data unit (SDU) and a second service data unit (SDU) for a source from a second protocol layer for transmission to a second communication device. The method can also include starting a first timer with a first initial value for the first SDU, and starting a second timer with a second initial value for the second SDU. The second initial value can be different from the first initial value in response to determining that the second SDU is to be routed differently from the first SDU to the second communication device.

摘要： Multiple wireless devices in a network perform full duplex communication in which the transmission path and receiving path are spatially separated to allow simultaneous transmission and receiving. The wireless devices can either be controlled using a centralized, or point, coordination function or a distributed coordination function. A full-duplex wireless device senses the medium during transmission by itself and selectively continues the transmission when a signal is sensed on the medium. A full-duplex wireless device measures signal being transmitted by its transmitter and estimates parameters that can be used to cancel the contribution of the locally transmitted signal to the locally received signal concurrently being received during the transmission. The transmit antenna and the receive antenna of a full-duplex wireless device can be configured to be spatially isolated from each other to minimize interference between the antenna functions.

摘要： A method and system for Quality of Service (QoS) during access negotiation are provided, which include that during media resource access negotiation, a calling side network element receives an INVITE 200 OK message from a called side terminal, detects that this call is under a SIP Forking scenario, only updates media resources negotiated by current session branch associated with the called side terminal, and does not process resource bearers negotiated by other session branches. A method and system for QoS bearer resource control during release is also provided, which include that during media resource release, a calling side network element receives a BYE message, and when detecting that this call is under an SIP Forking scenario, only releases media resources negotiated by current session branch, and does not process resource bearers negotiated by other session branches. By the disclosure, a resource bearer requirement of the SIP Forking scenario can be met.
摘要翻译：提供了一种在接入协商过程中服务质量（QoS）的方法和系统，其中包括在媒体资源接入协商期间，主叫侧网元从被叫侧终端接收到INVITE 200 OK消息，检测到该呼叫在 SIP分岔场景仅更新与被叫方终端相关联的当前会话分支协商的媒体资源，不处理其他会话分支协商的资源承载。还提供了一种在发布期间进行QoS承载资源控制的方法和系统，其中包括在媒体资源释放期间，主叫侧网元接收到BYE消息，并且当检测到该呼叫处于SIP分岔场景下时，只释放媒体资源由本会议部门协商，不处理其他会议分支机构协商的资源承载。通过该公开，可以满足SIP分支场景的资源承载要求。

摘要： A method and apparatus for performing a random access (RACH) procedure is disclosed. In one embodiment, a method performed by a wireless communication node, includes: performing a plurality of random access (RACH) procedures with a wireless communication device on a first frequency resource set and a second frequency resource set, wherein the plurality of RACH procedures each comprises: receiving a first message on a first frequency resource from the wireless communication device, wherein the first frequency resource is selected from the first frequency resource set; transmitting a second message on a second frequency resource to the wireless communication device within a pre-determined time window, wherein the second frequency resource is selected from the second frequency resource set; receiving a third message on the first frequency resource from the wireless communication device; and transmitting a fourth message on the second frequency resource to the wireless communication device.
