Abstract: Embodiments of the present invention disclose a PUSCH transmission method and apparatus. The method includes: sending, in a first subframe, downlink control signaling that instructs user equipment UE to transmit a physical uplink shared channel PUSCH, where the downlink control signaling carries downlink control information, and the downlink control information is used to indicate a subframe for transmitting the PUSCH, where the subframe for transmitting the PUSCH is any one of or any combination of N subframes, the N subframes include a special subframe, and N is an integer not less than 1; and receiving the PUSCH in the subframe indicated by the downlink control information. It can be seen that, in the embodiments of the present invention, a subframe in which a PUSCH is transmitted and that is indicated by downlink control information includes a special subframe; therefore, the special subframe can be scheduled to transmit the PUSCH.

Abstract: A network device and UEs are described, which support preemption of a transmission over a first link and provides to a first UE preemption information indicative of a first spatial filter that is to be preempted by the first UE for transmission over the first link. A second UE receives an indication from a network device to: perform a measurement of a reference signal on at least one second spatial filter, or transmit a reference signal on at least one second spatial filter; receive the reference signal from another UE and perform the measurement on the at least one second spatial filter, or transmit the reference signal to another UE on the at least one second spatial filter, according to the indication received from the network device; wherein the at least one second spatial filter is allocated by the UE for receiving over a second link.

Abstract: Example methods and apparatus for multihop transmission are described. One example method includes receiving a scheduling request by a network device from a User Equipment (UE) for a multihop transmission. The network device sends a first message to one or more UEs in response to the scheduling request, wherein the first message indicates one or more sidelink resources and/or sidelink resource allocation information for the one or more UEs to perform a multihop transmission.

Abstract: The present application relates to wireless communications suitable for smart manufacturing and industrial automation. In particular, the application proposes a wireless communication device (UE) and a network device (BS), in particular suitable for cyclic communication. The BS is configured to provide a first information defining a hopping sequence to a UE, and to provide a second information to the UE defining when the hopping sequence should be repeated, in particular periodically repeated. The UE is accordingly configured to receive the first information from the BS, and to receive the second information from the BS. The hopping sequence specifies at least two spatial resources and/or at least two radio resources, which the UE is configured to use for transmissions to and/or from the BS.

Abstract: A time domain resource indication method includes sending, by a first node, first time domain resource configuration information to at least one second node. The first time domain resource configuration information is used by the at least one second node to determine second time domain resource configuration information sent by the at least one second node to at least one third node. The first time domain resource configuration information indicates first time domain resources of a link between the first node and the at least one second node. The second time domain resource configuration information indicates second time domain resources of a link between the at least one second node and the at least one third node.
