Signal forwarding method and device

By implementing a processing mechanism for indicating that the index value of DCI 2_8 is out of range in the relay device, the relay device can not forward signals on the resource at the first time, or use a pre-configured access link beam forwarding signal, solving the problem of signal forwarding failure and improving communication efficiency.

AI Technical Summary

Technical Problem

In R18, when the relay device receives the index value of the non-periodic forwarding resource indicated by DCI 2_8 is not within the range that the relay device can recognize, an effective processing mechanism is lacking, resulting in signal forwarding failure.

Method used

When the relay device receives the first information, if the index value indicated by the first beam field is not within the first range or the index value indicated by the first time field is not within the second range, the relay device may not forward the signal on the first time resource, or use a preconfigured first access link beam forwarding signal.

Benefits of technology

It effectively solves the situation where the relay device cannot handle the DCI 2_8 indicating that the index value exceeds the range, ensures the normal progress of signal forwarding, and improves the processing capability and communication efficiency of the relay device.

Abstract

The invention provides a signal forwarding method and device, which can solve the problem of how to process by relay equipment when an index value indicated by network equipment is not in an index value range which can be identified by the relay equipment. The method comprises: a relay device receiving first information from a network device, a first beam field in the first information indicating a first index value, and a first time field associated with the first beam field indicating a second index value; if the first index value is not within the first range and the second index value is within the second range, the signal is not forwarded on the first time resource or the signal is forwarded on the first time resource by using a first access link beam, and the first access link beam is determined according to the first index value; or, if the second index value is not within the second range and the first index value is within the first range, ignoring the first time field and the first beam field or using a second access link beam to forward the signal on a second time resource, the second time resource being determined according to the second index value.
