摘要： A method implemented in a first communication node (110) for communicating with a second communication node (120) over an acknowledged connection (131), comprising: receiving a stream of code blocks from the second communication node, wherein each code block is associated with a check value enabling error detection and belongs to a predefined group of code blocks; detecting errors in received code blocks using respective associated check values; and transmitting to the second communication node an acknowledgement in respect of each of said predefined groups of code blocks, wherein a negative value of the acknowledgment signifies that an error was detected for at least one of the code blocks in the predefined group, wherein the acknowledgement for a predefined group of two or more code blocks is based on a combination of error detection results for a subset of the code blocks in the predefined group.

摘要： In one aspect, a wireless transmitter forms (1110) a first signal having a first integer number of symbol intervals in each of one or more time intervals of a predetermined length and forms (1120) a second signal having a second integer number of symbol intervals in each of the one or more time intervals of the predetermined length, the second integer number differing from the first integer number. The wireless transmitter simultaneously transmits(1130) the first and second signals in a frequency band, such that the first and second signals are frequency- domain multiplexed in the frequency band and such that a symbol interval starting time in the first signal is aligned with a corresponding symbol interval starting time in the second signal at least once per time interval.

摘要： For future wireless systems, it is desired to keep network implementation aspects, such as transmission point selection, precoder selection, etc, transparent to the terminal. This means that terminals are envisaged to be unaware of e.g. from which specific network node a transmission is made. This may be referred to as the transparency principle. The proposed solution comprises enabling a receiver to determine a type of antenna association that may be assumed in regard of two blocks of information, based on the result of the decoding of e.g. the first data block. The determination is done in a way such that the principle of transparency is not broken.
摘要翻译：对于未来的无线系统，期望将终端的透明点等传输点选择，预编码器选择等网络实现方面保持不变。这意味着终端被设想为不知道例如从哪个特定网络节点进行传输。这可以称为透明度原则。所提出的解决方案包括使得接收机能够基于例如解码的结果来确定关于两个信息块可以假设的天线关联的类型。第一个数据块。决心是以透明度原则不破坏的方式完成的。

摘要： Systems and methods for reducing signaling overhead between an Integrated Access and Backhaul (IAB) node and its parent node when switching between timing alignment cases are disclosed. In some embodiments, the method comprises sending one or more sets of desired numbers of guard symbols for two or more timing switching groups, respectively. The method further comprises receiving one or more sets of provided numbers of guard symbols for the two or more timing switching groups, respectively and determining available time resources for uplink transmission and/or downlink reception in two adjacent time units based on one of the one or more sets of provided numbers of guard symbols for one of the two or more timing switching groups that corresponds to timing alignment cases used in the two adjacent time units.

摘要： Systems and methods are disclosed herein for aligning transmission timing on different carrier frequencies in an Integrated Access and Backhaul (IAB) network. In one embodiment, a method performed by an IAB node for an IAB network comprises receiving, from an IAB parent node, information about a timing offset, T'D, wherein the timing offset, T'D, is equal to or a 5 function of a timing offset, TD, between a downlink timing of a first carrier at the IAB parent node and a downlink timing of a second carrier at the IAB parent node, the second carrier being different than the first carrier. The method further comprises deriving a downlink timing offset for the second carrier at the IAB node based on the information about the timing offset, T'D, and performing one or more downlink transmission at the IAB node on the second carrier based on 0 the derived downlink timing offset.

摘要： A method and apparatus are disclosed. A wireless device (WD) configured to communicate with a network node is provided. The WD comprises a radio interface and processing circuitry configured to: if a configured frequency hopping distance results in a resource allocation at two edges of a slot, apply a modified resource allocation that avoids resource allocation at two bandwidth part, BWP, edges. The modified resource allocation corresponds to a frequency hopping distance different from the configured frequency hopping distance. The radio interface and/orprocessing circuitry is further configured to transmit using the modified resource allocation.
