Referring to fig. 2, the method provided by the present application includes step 201 and step 202.

In step 201, the network device transmits a configuration of N sets of time domain resources and M beam indexes. Correspondingly, the relay device receives the configuration of the N groups of time domain resources and the M beam indexes. Specifically, the network device may configure the N sets of time domain resources and the M beam indexes through radio resource control (Radio Resource Control, RRC) signaling. One beam index may be used to represent one beam.

More specifically, each set of time domain resources may include: a starting time slot, a starting symbol, a duration, etc. of the time domain resource. Further, each set of time domain assets may also include periods of resources.

The indication information is used for indicating target beams and/or target time domain resources, the indexes of the target beams are selected from M beam indexes, the target time domain resources are selected from N groups of time domain resources, and the target time domain resources are time domain resources mapped by the target beams.

Specifically, the relay device may determine, according to the indication information, a target beam to be transmitted and a target time domain resource to which the target beam is mapped.

Step 203: the relay device transmits the target beam to the terminal device on the target time domain resource. Specifically, the relay device transmits the target beam over an access link (ACCESS LINK, a-link).

It should be noted that the serial numbers of the steps in the present embodiment do not represent a limitation on the execution sequence of the steps.

It will be appreciated that in a specific implementation, the communication method may be implemented in a software program running on a processor integrated within a chip or a chip module. The method may also be implemented by combining software with hardware, and the application is not limited.

In this embodiment, when associating the time domain resource with a beam, any one of the M beam indexes maps one or more time domain resources of the N sets of time domain resources. In other words, one beam index may correspond to one or more time domain resources, while one time domain resource corresponds to only one beam index.

In the embodiment of the invention, when the network equipment indicates the target beam and the target time domain resource through the indication information, the network equipment can directly indicate the associated beam and time domain resource; when the network device indicates the target beam or the target time domain resource through the indication information, the relay device can combine the preset mapping relation to realize association of the beam and the time domain resource, so that transmission of the target beam on the target time domain resource is realized, semi-continuous scheduling of the beam and the time domain resource is realized, signaling overhead is saved, and the flexibility of transmission can be improved.

The steps of the above communication method are described in detail below in connection with the different contents of the indication information.

Embodiment 1, the indication information indicates a target beam or a target time domain resource.

Referring to fig. 3, in step 301, a network device sends a configuration of N sets of time domain resources and M beam indexes to a relay device.

Specifically, the network device may configure N sets of time domain resources and M beam indexes through higher layer signaling, respectively. Specifically, the network device configures N sets of time domain resources and M beam indexes in two RRC signaling, respectively.

In one embodiment of step 302, the network device transmits a target beam to the relay device.

Accordingly, in step 303, the relay device determines the target time domain resource according to the target beam and the first mapping relation. The first mapping relationship is a mapping relationship between N groups of time domain resources and M beam indexes.

Specifically, the first mapping relationship may be preconfigured to the relay device by the network device, or may be specified in a communication standard, which is not limited by the present application.

In another embodiment of step 302, the network device sends the target time domain resource to the relay device. Accordingly, in step 303, the relay device determines a target beam according to the target time domain resource and the first mapping relation.

With continued reference to fig. 3, in step 304, the relay device transmits a target beam to the terminal device on a target time domain resource.

Referring also to fig. 4, the N sets of Time domain resources include Time domain resource (Time resource) 1, time domain resources 2, …, and Time domain resource N, respectively. Each time domain resource includes a start slot (start slot), a start symbol (start symbol), and a duration (duration) of the time domain resource. The M beam indexes include beam (beam) index 1, beam indexes 2, …, and beam index M, respectively.

In a specific implementation of step 302, the network device may send the target beam or the target time domain resource through high layer signaling, for example, through a media access Control (MEDIA ACCESS Control, MAC) Control Element (CE) to carry the target beam or the target time domain resource.

For example, M is equal to N, in the first mapping relationship, time domain resource 1 corresponds to beam index 1, time domain resource 2 corresponds to beam index 2, …, and time domain resource N corresponds to beam index N. The MAC CE indicates beam index 2. The relay device may determine the target time domain resource to be time domain resource 2, i.e., may transmit the beam indicated by beam index 2 on time domain resource 2.

For another example, M is less than N, and the beam indexes include beam index 1 and beam index 2, respectively; the time domain resources include time domain resources 1-5. In the first mapping relation, time domain resources 1,3 and 5 correspond to beam indexes 1; time domain resources 2,4 correspond to beam index 2. The MAC CE indicates beam index 2. The relay device may determine the time domain resource 2,4 as the target time domain resource, i.e. may transmit the beam indicated by the beam index 2 on the time domain resource 2, 4.

Embodiment 2, the indication information indicates an index of the target beam and information of the target time domain resource.

Referring to fig. 5, in step 501, the network device sends a configuration of N sets of time domain resources and M beam indexes to the relay device. The network device may configure the N sets of time domain resources and the M beam indexes through higher layer signaling, respectively. Specifically, the network device configures N sets of time domain resources and M beam indexes in two RRC signaling, respectively.

In step 502, the network device transmits the index of the target beam and information of the target time domain resource to the relay device.

In step 503, the relay device transmits a target beam to the terminal device on the target time domain resource.

In a specific implementation, the network device may select any one of the M beam indexes as the target beam, and select any one of the N sets of time domain resources as the target time domain resource. Referring also to fig. 4, the target beam is a beam indicated by a beam index 2, and the target time domain resource is a time domain resource 1. The relay device transmits the beam indicated by beam index 2 on time domain resource 1.

In this embodiment, the index of the target beam and the information indicating the target time domain resource are carried on different bits in the MAC CE.

Specifically, each field in the MAC CE is shown in table 1. Wherein a/D represents activation/deactivation, B2B1B0 is used to carry the index of the target beam for a total of 3 bits, and T3T2T1T0 is used to carry the information of the target time domain resource for a total of 4 bits.

Further, N groups of time domain resources are distributed in one or more time domain resource sets, time domain resources in the same time domain resource set have the same period, and time domain resources in different time domain resource sets have the same or different periods.

According to the embodiment of the invention, the associated target wave beam and the target time domain resource are dynamically indicated through the high-layer signaling, so that the number of the wave beam and the time domain resource is more, the combination mode is more flexible, and the flexibility of communication is improved.

Referring to fig. 6, in step 601, a network device sends a plurality of forwarding resource groups to a relay device. Each forwarding resource group includes a beam index and information for indicating a time domain resource corresponding to the beam index. Specifically, the network device carries multiple forwarding resource groups through RRC signaling.

In step 602, the network device sends an identification of a target forwarding resource group to the relay device. In this embodiment, the identifier of the target forwarding resource group is carried in the MAC CE.

In step 603, the relay device transmits the target beam to the terminal device on the target time domain resource.

Referring to fig. 7, the network device sends a forwarding resource group X1-Xn to the relay device, where the forwarding resource group X1-Xn is a combination of the beam index and the information of the corresponding time domain resource. For example, forwarding resource group X1 may be represented as { beam index 1, time domain resource 1}, forwarding resource group X2 may be represented as { beam index 2, time domain resource 2}, etc. The network device sends the identification X1 of the forwarding resource group to the relay device through the MAC CE. The relay device transmits the beam indicated by beam index 1 on time domain resource 1.

Further, the plurality of forwarding resource groups are distributed in one or more forwarding resource sets, time domain resources in the same forwarding resource set have the same period, and time domain resources in different forwarding resource sets have the same or different periods.
