    Abstract: A method includes sending, by a network device, first configuration information, and sending, by the network device, second configuration information. The first configuration information is useable to map a first reference signal to a first resource element set in a first time element. The first resource element set includes at least a first resource element. The second configuration information is useable to map a second reference signal to a second resource element set in a second time element. The second resource element set includes at least a second resource element. A frequency domain resource occupied by the first resource element overlaps a frequency domain resource occupied by the second resource element in response to the first time element and the second time element overlapping each other in a time domain.

    Abstract: This application proposes a reference signal transmission method and a device. The method includes: converting, by a sending device, a frequency domain reference signal from frequency domain to time domain, to generate a time domain reference signal, where the frequency domain reference signal includes a reference signal sequence mapped to a frequency domain resource group, the reference signal sequence is related to a Zadoff-Chu sequence and a length of the reference signal sequence, and a length value of the Zadoff-Chu sequence is greater than a quantity of minimum time-frequency resource units included in a maximum frequency domain resource that can be allocated; and sending, by the sending device, the time domain reference signal. According to the reference signal transmission method in this application, a performance requirement on a PAPR/RCM of a reference signal can be met, a quantity of blind reference signal detection times can be reduced, and system performance can be improved.

    Abstract: Technical solutions provided in this application may be applied to an extended reality XR service or another low-latency service. In a multi-hop scenario, after receiving a data packet sent by a previous-hop node and an encoding coefficient of the data packet relative to an original data packet, a forwarding node first determines a newest encoding coefficient based on the encoding coefficient received by the forwarding node from the previous-hop node and an encoding coefficient newly obtained by the forwarding node, and encodes, by using the newest encoding coefficient, the data packet received by the forwarding node from the previous-hop node. In this case, a data packet obtained through encoding is essentially a data packet obtained by the forwarding node by encoding the original data packet by using the newly obtained encoding coefficient. An encoding calculation amount can be further reduced while network recoding is implemented, thereby improving an encoding rate.

    Abstract: This application provides a data sending method and an apparatus. The method includes performing, by a node, soft modulation to generate a modulation symbol. The method also includes preprocessing, by the node, the modulation symbol to obtain to-be-sent data. The preprocessing includes one or more of layer mapping, antenna port mapping, precoding, or transform precoding. The method further includes mapping, by the node, the to-be-sent data to a physical resource, and sending the to-be-sent data by way of the physical resource.
