摘要： Embodiments herein relate to a method performed by a network node (110) in a wireless communications network (100) for handling Automatic Repeat reQuest, ARQ, feedback information from a wireless device (121) relating to downlink transmissions from the network node (110). The network node (110) obtains an indication of a downlink processing delay for the ARQ feedback information from the wireless device (121). Then, the network node (110) considers the ARQ feedback information relating to a downlink transmission from the wireless device (121) to be invalid when, according to the obtained indication of a downlink processing delay, the downlink transmission has not been processed by the wireless device (121). Embodiments of the network node (110) are also described.Furthermore, embodiments herein further relate to a wireless device (110) and method therein for enabling a network node (110) in a wireless communications network (100) to handle Automatic Repeat reQuest, ARQ, feedback information from the wireless device (121) relating to downlink transmissions from the network node (110).

摘要： Embodiments of the present disclosure generally relate to handling of connection setups. More particularly, they relate to a method performed in a UE (4) for requesting a connection set up with a network node (2). The UE (4) receives a signal comprising a set of classifying parameters and based on these parameters determines at least one class to which it belongs to. The UE (4) also receives a PRACH preamble scheme associated with said class to be used by the UE (4) during a connection setup request. The method further controls the timing of transmitting at least one request, signal for requesting a connection setup with the network node (2) according to the received PRACH preamble scheme. Embodiments herein also relate to a method performed in a network node (2), and to a network node (2) and to a UE (4).

摘要： A system and method of Random-Access Response, RAR, messaging when a base station employs narrow beamforming. Multiple RAR messages are successively transmitted from the base station to a User Equipment, UE, before any response to a RAR message is received from the UE. Thus, despite any calibration mismatch between Uplink, UL, and Downlink, DL, beams in the beamformed system, a RAR message is not only received by the UE, but is received over the most-suitable DL beam for that UE. Each RAR message may contain a message-specific scheduling-delay indicator in the UL grant carried in the RAR message to provide an adjustable time delay for the UE's uplink transmission scheduled by the UL grant. Multiple RAR transmissions can schedule a single UL transmission at a specific time instance or different UL transmissions at different time intervals. The UE may report to the base station the best DL RAR transmission detected by the UE.
摘要翻译：当基站采用窄波束成形时，随机接入响应（RAR）消息的系统和方法。在从UE接收到对RAR消息的任何响应之前，多个RAR消息从基站连续发送到用户设备UE。因此，尽管波束形成系统中的上行链路，UL和下行链路DL之间的校准不匹配，RAR消息不仅被UE接收，而且在该UE的最适合的DL波束上被接收。每个RAR消息可以在RAR消息中携带的UL授权中包含消息特定的调度延迟指示符，以为由UL授权调度的UE的上行链路传输提供可调整的时间延迟。多个RAR传输可以在特定时间或不同时间间隔的不同的UL传输中调度单个UL传输。 UE可以向基站报告由UE检测到的最佳DL RAR传输。

摘要： The present invention relates to assigning addresses to communication devices in a radio access network and notifying communication devices of scheduled uplink transmission time periods. Related methods, communication devices and control units are disclosed. A method of assigning an address to a communication device in a radio access network for use in notification of scheduled uplink transmission time periods for the communication device is provided. The method comprises assigning to the communication device an uplink state flag (USF) value. Furthermore, the method comprises assigning to the communication device an extended USF (eUSF) value. The address assigned to the communication device is a combination of the assigned USF value and the assigned eUSF value. By means of the eUSF value, the normal address range provided by the USF is extended, thereby facilitating use of more communication devices in the radio access network.

摘要： There is provided load sharing performed by a first processing unit device and a second processing unit device. The load sharing is achieved by the first processing unit device determining a distinct subset of user equipment, UE, from a set of UEs, where the UEs of the distinct subset of UEs are candidates for load sharing. Information identifying the UEs in the distinct subset and information of load of a first cell in which the distinct subset of UEs are served and information of load of a second cell being a candidate cell for serving the distinct subset of UEs is transmitted to the second processing unit device. Based on evaluating the information received from the first processing unit device the second processing unit device determines a load sharing action for use by the first processing unit device.
