AI Technical Summary

Technical Problem

In non-terrestrial networks, the difference in operating altitude between network equipment and terrestrial network equipment leads to increased resource consumption and reduced system capacity and throughput when covering a wide area and serving multiple terminal devices.

Method used

By performing OCC extension on the Physical Uplink Shared Channel (PUSCH) within K first time units, conflicts with the Physical Random Access Channel (PRACH) or the Sounding Reference Signal (SRS) are avoided, ensuring the orthogonality of PUSCH data. The OCC sequence is then used for code division multiplexing or extension to optimize resource utilization.

Benefits of technology

It improves the success rate of the network side in correctly receiving uplink data, enhances system capacity and performance, and avoids the negative impact of resource conflicts on data transmission.

Abstract

Provided in the embodiments of the present application are a communication method and an application apparatus, which can be applied to the field of satellite communications, such as NTNs. The method comprises: when one or more PUSCHs to be sent on K first time units collide with one or more PRACHs or SRSs to be sent on one or more second time units, sending uplink data on a PUSCH of each of the K first time units, wherein the uplink data is data obtained by multiplying data carried on the PUSCH by an OCC element corresponding to the first time unit in an OCC sequence. By using the embodiments of the present application, how to transmit data carried on a PUSCH when colliding with others can be indicated, thereby reducing the impact on the orthogonality between transmissions of the data carried on the PUSCH, and facilitating correct reception of the data by a network side.
