Abstract: A time division duplex (TDD) scheduling interval communicating transmissions in a first direction may include one or more regions for communicating in a second direction, where the first direction is a transmit direction and the second direction is a receive direction, or vice versa. A radio frame may include TDD scheduling intervals with such regions and/or TDD scheduling intervals without such regions for wireless communication, and these TDD scheduling intervals may further be configured in accordance with different frame structure configurations, such as different scheduling interval lengths, subcarrier spacings or symbol durations.
Abstract translation: 在第一方向上传送传输的时分双工（TDD）调度间隔可以包括用于在第二方向上进行通信的一个或多个区域，其中第一方向是发送方向，第二方向是接收方向，反之亦然。 无线电帧可以包括具有这样的区域和/或TDD调度间隔的TDD调度间隔，而没有用于无线通信的这样的区域，并且这些TDD调度间隔还可以根据不同的帧结构配置来配置，诸如不同的调度间隔长度，子载波间隔 或符号持续时间。

Abstract: A resource multiplexing method and apparatus are provided, to determine a set of available symbols in an NR IAB system. A first node determines a time domain position of a DU resource of a communications device, and determines a time domain position of an MT resource of the communications device based on the time domain position and a type of the DU resource and guard interval information. Alternatively, a first node determines a time domain position of an MT resource of a communications device, and determines a time domain position of a DU resource of the communications device based on the time domain position and a type of the MT resource and guard interval information.

Abstract: This application provides example resource configuration methods, example apparatuses, and example computer-readable storage medium. One example method includes obtaining, by a distributed unit (DU) side of a first node, a first resource configuration and at least one second resource configuration, where the first resource configuration indicates the DU side of the first node to communicate with at least one of a terminal device or a second node by using the first resource configuration, the second resource configuration indicates the DU side of the first node to communicate with the second node by using the second resource configuration, the first node is a relay node, and the second node is a child node of the first node. The DU side of the first node can then communicate with the at least one of the terminal device or the second node.

Abstract: This present disclosure discloses example random access resource configuration methods, mediums, and apparatuses. One example method includes receiving, by a first network device, configuration information of a first physical random access channel (PRACH) resource. Location adjustment information is received by the first network device, where the location adjustment information is used to indicate to adjust a location of at least a part of the first PRACH resource. A second PRACH resource is determined by the first network device based on the configuration information of the first PRACH resource and the location adjustment information. A random access request is sent by the first network device to a second network device on the second PRACH resource.

Abstract: Examples synchronization signal configuration methods and apparatus are described. One example method is applied to a relay network including a first node and a second node, and the first node is a parent node of the second node. The example method includes sending synchronization signal configuration information by the first node to the second node, where the synchronization signal configuration information is used to indicate M first synchronization signal time-frequency positions and N second synchronization signal time-frequency positions in a candidate synchronization signal time-frequency position set. The first synchronization signal time-frequency position is used by the second node to send a first synchronization signal, the second synchronization signal time-frequency position is used by the second node to receive or detect a second synchronization signal, the candidate synchronization signal time-frequency position set includes W synchronization signal time-frequency positions, and W≥(M+N).

Abstract: A method for wireless communications includes receiving signaling for indicating a time division duplexing (TDD) frame structure configuration from a base station. The TDD frame structure configuration corresponds to a time duration of 0.1 ms, 0.125 ms, 0.2 ms, 0.25 ms, 0.5 ms, or 1.0 ms, the TDD frame structure configuration including two switching points between downlink transmissions and uplink transmissions. The method further includes communicating downlink and uplink transmissions according to the TDD frame structure configuration. The TDD frame structure configuration may further include a guard period for separating the first downlink transmission and the first uplink transmission in the time domain.
