As an optional embodiment, in case that the DCI is used to activate downlink semi-static scheduling or uplink configuration grant for at least two terminals,

Further, the method further comprises:
and receiving or transmitting the physical shared channel on the determined physical resource position.
Example 1
The first parameter is that the network side configures a first time domain resource allocation offset value and/or a second frequency domain resource allocation offset value for the terminal.
And the terminal determines the physical resource allocation of the physical shared channel according to the time domain and/or frequency domain resource allocation indicated by the second information domain carried by the DCI and the first time domain resource allocation offset value and/or the second frequency domain resource allocation offset value. For example, the terminal determines physical resource allocation of a physical shared channel according to the time domain and/or frequency domain resource allocation indicated by the DCI plus the first time domain resource allocation offset value and/or the second frequency domain resource allocation offset value.
For example, the network side configures a time domain resource allocation offset value for the terminal to be 3 slots, and/or a frequency domain resource allocation offset value to be 2 PRBs, where the time domain resource allocation positions indicated by the second information field in the DCI are symbols 3 to 10 in a slot N, and the indicated frequency domain resource allocation positions are PRBs 0 to 5. The time domain resource allocation positions of the traffic channels determined by the terminal are symbols 3 to 10 of N +3 slots, and the frequency domain resources are allocated as PRB 2 to PRB 7.
Example two
And the terminal determines the offset value of the resource allocation according to the terminal index and the time domain/frequency domain resource offset value predefined by the network side or the protocol according to the time domain and/or frequency domain resource allocation indicated by the second information domain carried by the DCI, and finally determines the physical resource allocation of the service channel by combining the two parts.
The method comprises the following specific steps:
the first parameter is an index of the terminal and/or a first time domain resource allocation offset value and/or a second frequency domain resource allocation offset value.
And the terminal determines the physical resource allocation of the service channel according to the time domain and/or frequency domain resource allocation indicated by the second information domain carried by the DCI, the index of the terminal and/or the first time domain resource allocation offset value and/or the second frequency domain resource allocation offset value. Further, the terminal with the index of a specific value determines the physical resource position of the service channel only according to the second information field carried by the DCI.
Specifically, the terminal determines the time domain resource allocation offset value and/or the frequency domain resource allocation offset value of the terminal according to the index of the terminal and the first time domain resource allocation offset value and/or the second frequency domain resource allocation offset value, and determines the physical resource allocation of the service channel of the terminal according to the time domain and/or frequency domain resource allocation offset value indicated by the second information domain carried by the DCI.
For example, the network configures an index k for the terminal, and configures a first time domain resource allocation offset value to be 1 timeslot. And the time domain resource allocation positions indicated by the second information domain in the DCI are symbols 3 to 10 in a time slot N. The time domain resource allocation positions of the traffic channel determined by the terminal with the index of k are symbols 3 to 10 of the N + k slot.
For another example, the network configures an index k for the terminal, and configures a second frequency-domain resource allocation offset value to be 2 PRBs. And the frequency domain resource allocation positions indicated by the second information domain in the DCI are PRB 0 to PRB 5. The frequency domain resource allocation positions of the traffic channels determined by the terminal with index k are PRB (0+2 × k) to PRB (5+2 × k).
For another example, the network side configures an index k for the terminal, and the protocol predefines a first time domain resource allocation offset value of 1 timeslot. And the time domain resource allocation positions indicated by the second information domain in the DCI are symbols 3 to 10 in a time slot N. The time domain resource allocation positions of the traffic channel determined by the terminal with the index of k are symbols 3 to 10 of the N + k slot.
For another example, the network side configures an index k for the terminal, the index of the starting PRB allocated for the frequency domain resource indicated by the second information field in the DCI is s, and the length of the allocated PRB is l. The starting PRB index of the frequency domain resource allocation of the terminal with the protocol predefined index k is s + l × k, and the allocated PRB length is l.
As another optional embodiment, in case that the DCI is used to activate downlink semi-static scheduling or uplink configuration grant for at least two terminals,
the DCI carries a first information field, and the value of the first information field is a predefined numerical value. The predefined value is defined to indicate activation.
Wherein the method further comprises:
receiving related information of downlink semi-persistent scheduling or uplink configuration authorization configured for a terminal by network side equipment through a high-level signaling; for example, SPS periodicity and HARQ feedback resources are configured for the terminal;
and activating the relevant information of the downlink semi-static scheduling or activating the relevant information of the uplink configuration authorization according to the activation indication.
Further, the DCI carries a second information field, where the second information field is used to indicate allocation information of time domain resources and/or frequency domain resources.
Optionally, the method further comprises:
determining the resources of the physical shared channel according to the second information domain and the first parameter;
the first parameter is configured or predetermined by the network side device through a high-level signaling.
Wherein the first parameter comprises at least one of:
an index of the terminal;
a time domain resource allocation offset value;
a frequency domain resource allocation offset value.
As an optional embodiment, the determining the resource of the physical shared channel according to the second information field and the first parameter includes:
determining the physical resource position of the physical shared channel according to the physical resource position indicated by the second information domain and the physical resource offset value determined by the first parameter; the physical resources are time domain resources and/or frequency domain resources.
Further, the method further comprises:
and receiving or transmitting the physical shared channel on the determined physical resource position.
As a result, the network side device may also send a single DCI to respectively schedule and release the downlink SPS or uplink configuration grant of different terminals. The CRC of the DCI is scrambled by the RNTI of the single terminal.
In summary, in the embodiment of the present invention, the network side device performs resource scheduling for multiple terminals or SPS activation for multiple terminals or uplink configuration authorization activation for multiple terminals through one DCI, so as to effectively reduce signaling overhead of a control channel on the network side.
