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： A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.

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： A method by a user equipment is disclosed for decoding data from a network node in a telecommunications system. The method includes determining whether a discovery signal was received from the network node by detecting of another signal received from the network node, which may be a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS). Based on detecting that the another signal was received, the method includes determining whether a grant is present based on processing an Evolved Physical Downlink Control CHannel, ePDCCH. Based on determining that a grant is present, the method includes decoding a Physical Downlink Shared Channel, PDSCH, using the ePDCCH and the discovery signal.

摘要： The present disclosure relates to random access in wireless communication systems, and in particular to transmitting, receiving, and detecting preamble sequences. A method in a wireless device for transmitting a preamble sequence to a network node is disclosed. The method comprises configuring a number of preamble sequences into two or more preamble sets, wherein each preamble set is associated with at least one respective uplink transmission condition; determining a transmission condition of an uplink from the wireless device to the network node; and selecting one out of the two or more preamble sets based on the determined transmission condition to be a selected preamble set, and a preamble sequence from the selected preamble set to be a selected preamble sequence; as well as transmitting the selected preamble sequence on the uplink.

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： Techniques according to which HARQ feedback transmitted from a wireless device to a base station includes not only the ACK/NACK status for the corresponding hybrid automatic-repeat-request, HARQ, process, but also certain information that was provided by the network in the last received downlink assignment. An example method, as implemented in a wireless device operating in a wireless communication network, comprises receiving (610) from the wireless communication network, in a first transmission-time interval, a resource-assignment message indicating resources allocated for a data transmission to the wireless device. The example method further comprises transmitting (620) to the wireless communication network, in a second transmission-time interval, feedback information that includes an indication of whether the data transmission was correctly received by the wireless device and further includes one or more mirrored information fields copied from the resource-assignment message.
