Description

Information configuration method and equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for configuring information.

Background

Currently, the Multiple Access methods adopted in the 4G LTE (Long Term Evolution) system and the current version of the 5G NR (new radio) standard are all orthogonal Multiple Access, for example, SC-FDMA (Single-carrier Frequency-Division Multiple Access) or OFDMA (orthogonal Frequency Division Multiple Access) is adopted in the uplink in 5G, and OFDMA (orthogonal Frequency Division Multiple Access) is adopted in the downlink. When data transmission is performed by using ofdma, a certain frequency offset (hereinafter referred to as frequency offset) exists between carrier frequencies of a base station and a terminal due to different clock sources used by the base station and the terminal and instability of the clock source itself. Frequency offset between the base station and the terminal may cause symbol phase deflection and inter-subcarrier interference in the frequency domain, thereby affecting system performance.

In practical application, the receiving end estimates the frequency offset and compensates the frequency offset when receiving data subsequently, thereby reducing or avoiding the influence of the frequency offset on the system performance.

With the continuous evolution of the 4G technology and the development of the 5G technology, the non-orthogonal multiple access is widely concerned, then when uplink data transmission is performed in a non-orthogonal multiple access transmission mode, signals of multiple users are superposed on the same time-frequency resource, and due to different clock sources and instability of the clock sources, frequency offset values among the multiple users are different.

In summary, in the case of non-orthogonal multiple access transmission, there is a frequency offset between multiple users.

Disclosure of Invention

The invention provides an information configuration method and equipment, which are used for solving the problem that frequency offset exists among multiple terminals in non-orthogonal transmission in the prior art.

In a first aspect, an embodiment of the present invention provides an information configuration method, including:

and the network side equipment sends the sending signal frequency offset information used for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal.

According to the method, the network side equipment sends the sending signal frequency offset information used for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal, and the terminal receives the sending frequency offset information used for adjusting the frequency offset during the non-orthogonal transmission of the terminal and sent by the network side equipment, so that the sending signal frequency offset information of a plurality of terminals for sending data is the same, and further the influence of multi-user frequency offset on the performance of the non-orthogonal transmission can be reduced.

In a possible implementation manner, the frequency offset information of the transmission signal is a frequency offset value of the transmission signal, and may also be named as 'frequency offset information' or 'frequency offset compensation information of the transmission signal', and the like, and is mainly used for representing the frequency offset value of the transmission signal of the terminal, or the frequency offset compensation value used by the terminal to adjust the frequency offset of the terminal.

The network side equipment sends sending signal frequency offset information used for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal, and the method comprises the following steps:

and the network side equipment sends the frequency offset information of the sending signal to a terminal through an RRC (Radio Resource Control) signaling.

In the method, when the sending signal frequency offset information is the sending signal frequency offset value, the network side device sends the sending signal frequency offset value information to the terminal through the RRC signaling. Because the network side equipment configures the parameters for transmission in advance through the RRC signaling, the terminal for data transmission can receive the frequency offset information when receiving the transmission parameters by adding the frequency offset information in the RRC signaling, thereby saving transmission resources.

In a possible implementation manner, the frequency offset information of the transmission signal is an updated frequency offset value of the transmission signal, and may also be named as 'frequency offset information' or 'frequency offset compensation information of the transmission signal', and the like, and is mainly used for representing the frequency offset value of the transmission signal of the terminal, or the frequency offset compensation value used by the terminal to adjust the frequency offset of the terminal.

The network side equipment sends sending signal frequency offset information used for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal, and the sending signal frequency offset information comprises the following steps:

the network side device sends the sending signal frequency offset information to the terminal through an RRC signaling or a MAC CE (Medium Access Control protocol Control element) signaling.

In the method, when the frequency offset information of the transmission signal is the frequency offset value of the transmission signal update, the network side equipment transmits the frequency offset information of the transmission signal to the terminal through RRC signaling or MAC CE signaling. Because the base station configures parameters for transmission in advance through the RRC signaling, the terminal for data transmission can receive the frequency offset information when receiving the transmission parameters by adding the frequency offset information in the RRC signaling, thereby saving transmission resources; due to the slow variability of the frequency offset over time, the frequency offset information may be transmitted by the MAC CE.

In one possible implementation, the method further includes:

if the updating mode is a stepping updating mode, the network side equipment takes the adjustment step value as the sending signal updating frequency offset value;

and if the updating mode is an absolute value updating mode, the network side equipment takes the target frequency offset value required to be adjusted as the sending signal updating frequency offset value.

The method provides two updating modes, and the frequency offset value of the sending signal used for adjusting the frequency offset during the non-orthogonal transmission of the terminal can be updated through the two updating modes, so that the frequency offset value of the sending signal is more flexibly updated.

In one possible implementation, the method further includes:

the network side equipment informs the terminal of the updating mode through RRC signaling or MAC CE signaling; and/or

And the network side equipment informs the terminal to update the frequency offset value of the transmitted signal through RRC signaling or MAC CE signaling.

In the method, the network side equipment can inform the terminal of the updating mode through RRC signaling or MAC CE signaling and can also inform the terminal of updating the frequency offset value of the transmitted signal through the RRC signaling or MAC CE signaling, so that no frequency offset exists between the terminals needing data transmission, and the influence of multi-user frequency offset on the performance of non-orthogonal transmission is further reduced.

In a possible implementation manner, the RRC signaling is RRC signaling that the network side device configures a pre-scheduling resource scheduling mode for the terminal.

When the RRC signaling configures the RRC signaling of the pre-scheduling resource scheduling mode for the terminal for the network side equipment, the signaling is used for sending data, so that transmission resources can be saved.

In a possible implementation manner, the time-frequency resources for non-orthogonal transmission are scheduled by configuring a pre-grant.

In a second aspect, an embodiment of the present invention provides an information configuring method, where the method includes:

the terminal receives sending signal frequency offset information which is sent by network side equipment and used for adjusting the frequency offset during non-orthogonal transmission of the terminal;

and the terminal adjusts the frequency offset value of the transmitted signal according to the frequency offset information of the transmitted signal.

In the method, the terminal firstly receives the frequency offset information of the sending signal, which is sent by the network side equipment and used for adjusting the frequency offset during the non-orthogonal transmission of the terminal, and then adjusts the frequency offset value of the sending signal of the terminal according to the frequency offset information of the sending signal, so that the frequency offset information of a plurality of terminals needing data transmission is the same, namely, no frequency offset exists among the terminals, and the influence of multi-user frequency offset on the performance of the non-orthogonal transmission is further reduced.

The terminal adjusts the frequency offset value of the sending signal of the terminal according to the frequency offset information of the sending signal, and the method comprises the following steps:

and the terminal takes the frequency offset information of the sending signal received through the RRC signaling as a frequency offset value of the sending signal.

In the method, when the transmitted signal frequency offset information is the transmitted signal frequency offset value, the terminal takes the transmitted signal frequency offset information received through the RRC signaling as the transmitted signal frequency offset value. Because the base station configures parameters for transmission in advance through the RRC signaling, the frequency offset information can be added in the RRC signaling, and after the terminal receives the frequency offset information through the RRC signaling, the received frequency offset information is used as a sending signal frequency offset value, so that the sending signal frequency offset values of a plurality of terminals needing data transmission are the same, namely no frequency offset exists among the terminals, and the influence of multi-user frequency offset on the performance of non-orthogonal transmission is further reduced.

and the terminal updates the frequency offset value of the sending signal of the terminal according to the frequency offset information of the sending signal and the updating mode.

According to the method, when the frequency offset information of the sending signal is the sending signal updating frequency offset value, the terminal updates the frequency offset value of the sending signal of the terminal according to the frequency offset information of the sending signal and the updating mode, so that the frequency offset values of the sending signals of a plurality of terminals needing data transmission are the same, namely, no frequency offset exists among the terminals, and the influence of multi-user frequency offset on the performance of non-orthogonal transmission is further reduced.

In a possible implementation manner, the updating, by the terminal, the frequency offset value of the transmission signal according to the update frequency offset value of the transmission signal and the update mode includes:

if the updating mode is a stepping updating mode, the terminal adds the updating frequency offset value of the sending signal to the frequency offset value of the current sending signal;

and if the updating mode is an absolute value updating mode, the terminal takes the updated frequency offset value of the sending signal as the frequency offset value of the sending signal.

The method provides two modes for updating the frequency offset value of the signal sent by the terminal, and adds the updated frequency offset value of the signal sent at present to the frequency offset value of the signal sent at present and uses the updated frequency offset value of the signal sent as the frequency offset value of the signal sent by the terminal, thereby enabling the update of the frequency offset value of the signal sent by the terminal to be more flexible.

In one possible implementation, the method further includes:

and the terminal receives the updating mode through RRC signaling or MAC CE signaling.

In the method, the terminal receives the updating mode through RRC signaling or MAC CE signaling, thereby saving transmission resources.

In a possible implementation manner, before the terminal adjusts the frequency offset value of the transmission signal according to the frequency offset information of the transmission signal, the method further includes:

and the terminal determines that the network side equipment notifies to update the frequency offset value of the transmitted signal through RRC signaling or MAC CE signaling.

In the method, after the terminal notifies the network side equipment of updating the frequency offset value of the transmitted signal through RRC signaling or MAC CE signaling, the terminal adjusts the frequency offset value of the transmitted signal according to the frequency offset information of the transmitted signal, so that the adjusted frequency offset values of the transmitted signals of a plurality of terminals needing data transmission are the same, namely, no frequency offset exists among the terminals, and the influence of multi-user frequency offset on the performance of non-orthogonal transmission is further reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Currently, Non-Orthogonal multiple access (NOMA) technology is receiving wide attention, and the 5G NR standard is also performing a relevant discussion on a transmission scheme combining the NOMA technology.

Under a non-orthogonal transmission mode, a plurality of user signals can be superposed on the same time-frequency resource, and due to the fact that a clock source used by each user may be different and the clock source itself is unstable, carrier frequencies of a plurality of users may be different, namely, frequency offset exists among the users, and a base station cannot perform frequency offset estimation according to the carrier frequencies of the users, so that the carrier frequencies of the users need to be adjusted, so that the frequency offset does not exist among the users, and therefore, a network side device performs estimation according to the adjusted frequency offset, performs frequency offset compensation during subsequent data receiving, and further reduces the performance influence of the non-orthogonal transmission caused by the frequency offset of the users.

The application scenario described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not form a limitation on the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In view of the above scenario, a system structure diagram for information configuration provided by the present application is specifically shown in fig. 1, where the system includes:

the network side device 10 is configured to send, to the terminal, transmission signal frequency offset information used for adjusting frequency offset during non-orthogonal transmission of the terminal.

The terminal 20 is configured to receive transmission signal frequency offset information, which is sent by the network side device and used for adjusting the frequency during terminal non-orthogonal transmission; and adjusting the frequency offset value of the sending signal according to the frequency offset information of the sending signal.

In the embodiment of the invention, firstly, the network side equipment sends the sending signal frequency offset information for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal, after the terminal receives the sending signal frequency offset information, the sending signal frequency offset value of the terminal is adjusted according to the sending signal frequency offset information, and as the terminal adjusts the sending signal frequency offset value according to the received sending signal frequency offset information, the frequency offset information of a plurality of terminals needing data transmission is the same in a non-orthogonal transmission mode, namely, no frequency offset exists among the terminals, thereby reducing the influence of multi-user frequency offset on the performance of the non-orthogonal transmission.

The terminal in the embodiment of the invention is a device with a wireless communication function, can be deployed on land and comprises an indoor or outdoor terminal, a handheld terminal or a vehicle-mounted terminal; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal may be a mobile phone (mobile phone), a tablet computer (pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.; but also UEs (users), Mobile Stations (MSs), and terminal equipment (terminal devices) in various forms.

The network side device is a device for providing a wireless communication function for the terminal, and includes but is not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B or home node B, HNB), a BaseBand Unit (BBU), a transmission point (TRP), a Transmission Point (TP), a mobile switching center (msc), and the like.

It should be noted that, in the embodiment of the present invention, the time-frequency resource of non-orthogonal transmission is scheduled by configuring a pre-grant.

In an implementation, the information about the frequency offset of the transmission signal may be a value of the frequency offset of the transmission signal, or may be an updated value of the frequency offset of the transmission signal. If the frequency offset information of the sending signal is the frequency offset value of the sending signal, the terminal takes the received frequency offset value of the sending signal as the frequency offset value of the sending signal of the terminal; if the frequency offset information of the sending signal is the updating frequency offset value of the sending signal, the terminal updates the frequency offset value of the sending signal of the terminal according to the received updating frequency offset value of the sending signal.

That is, the terminal adjusts the frequency offset value of the transmission signal, and may directly use the received frequency offset information of the transmission signal as the frequency offset value of the transmission signal of the terminal, or update the current frequency offset value of the transmission signal of the terminal according to the received frequency offset value of the transmission signal.

The following describes that the transmission signal frequency offset information is a transmission signal frequency offset value and a transmission signal update frequency offset value, respectively.

When the transmission signal frequency offset information is a transmission signal frequency offset value, the network side device may first determine a transmission signal frequency offset value used for adjusting frequency offset during non-orthogonal transmission of the terminal, and then transmit the transmission signal frequency offset value to the terminal through an RRC signaling.

It should be noted that, a pre-scheduling transmission method (transmission with configured grant) is introduced in the 5G NR standard, and the base station configures related parameters for transmission in advance through RRC signaling. The user performs data transmission on the pre-scheduled time-frequency resource by adopting a pre-configured transmission parameter in a direct mode or a mode triggered by an L1 signal without sending a Scheduling Request (SR) and waiting for a dynamic Scheduling signaling, thereby reducing data transmission delay and control signaling overhead required by dynamic Scheduling. Therefore, the network side equipment can increase the sending signal frequency offset value in the RRC signaling of the network side equipment configuring the pre-scheduling resource scheduling mode for the terminal, thereby saving transmission resources.

That is to say, the RRC signaling in the embodiment of the present invention may be RRC signaling in which the network side device configures a pre-scheduling resource scheduling mode for the terminal.

In order to facilitate understanding, a frequency offset value of a transmission signal is added to RRC signaling in which a network side device configures a pre-scheduling resource scheduling mode for a terminal, which is described below by way of example.

For example, the RRC signaling configured for pre-scheduling in TS38.311 is configured as ConfiguredGrantConfig, in which a non-orthogonal carrier offset (non-orthogonal carrier offset) field is added, and the contents of the field are as follows:

in the nomacarrioffset field, carrieroffset indicates a transmission signal frequency offset value, and maxnrofoffset sets indicates a maximum frequency offset value of a transmission signal.

Wherein, the determination of the transmission signal frequency offset value indicated by carrieroffset can be calculated by the network side equipment according to the historical data of the terminal; the maximum frequency offset value of the maxnrofffseturnits indication transmission signal may be preset, or may be calculated by the network side device according to the historical data of the terminal.

It should be noted that the frequency offset value of the transmission signal indicated by carrieroffset cannot be greater than the maximum frequency offset value of the transmission signal indicated by maxnrofffseturnis, and if the frequency offset value of the transmission signal indicated by carrieroffset is greater than the maximum frequency offset value of the transmission signal indicated by maxnrofffseturnis, the network side device needs to recalculate the transmission signal frequency offset value or the maximum frequency offset value of the transmission signal.

The unit of the frequency offset value of the transmitted signal is the frequency offset granularity (KHZ), which may be a value preset in the standard.

After the terminal takes the frequency offset value of the transmission signal sent by the network side equipment through the RRC signaling as the frequency offset value of the transmission signal of the terminal, the frequency offset values of the transmission signals of the plurality of terminals in the non-orthogonal transmission mode are all the frequency offset values of the transmission signal sent by the network side, so that the frequency offset values of the transmission signals of the plurality of terminals are the same, namely no frequency offset exists among the plurality of terminals, and the influence of the multi-user frequency offset on the performance of the non-orthogonal transmission is reduced.

The above is an explanation of the transmission signal frequency offset information being a transmission signal frequency offset value, and the following is an explanation of the transmission signal frequency offset information being a transmission signal update frequency offset value.

When the frequency offset information of the transmission signal is a frequency offset value of the transmission signal update, after the network side equipment determines the frequency offset value of the transmission signal update used for adjusting the frequency offset during non-orthogonal transmission of the terminal, the frequency offset value of the transmission signal update is transmitted to the terminal through RRC signaling or MAC CE signaling, and the terminal receives the frequency offset value of the transmission signal update through the RRC signaling or MAC CE signaling.

It should be noted that, by sending and receiving the sending signal through the RRC signaling to update the frequency offset value, the transmission resource can be saved; in addition, the TS38.321 may update the frequency offset value by transmitting and receiving a transmission signal by the MAC CE.

In implementation, if the network side device sends the sending signal update frequency offset value to the terminal through RRC signaling, in order to save transmission resources, the sending signal update frequency offset value may be placed in RRC signaling in which the network side device configures a pre-scheduling resource scheduling mode for the terminal, or may be placed in a separate RRC signaling.

For convenience of understanding, the following description will be given by exemplifying that the transmission signal update frequency offset value is placed in RRC signaling in which the network side device configures a pre-scheduling resource scheduling mode for the terminal.

For example, the RRC signaling configured in the TS38.311 for pre-scheduling is configured as ConfiguredGrantConfig, in which a noma erroffset field is added, and the field contents are as follows:

wherein, the offset update indicates that the sending signal updates the frequency offset value. As can be seen from the above field contents, the added nomacarrioffset field has a transmission signal update frequency offset value in addition to the transmission signal frequency offset value.

It should be noted that the range of the updated frequency offset value of the transmission signal is the same as the range of the frequency offset value of the transmission signal, and the updated frequency offset value cannot be larger than the maximum frequency offset value of the maxnrofffseturnits indication transmission signal.

When the frequency offset value of the transmission signal of the terminal needs to be updated, the network side device may notify the terminal to update the frequency offset value of the transmission signal through an RRC signaling, or may notify the terminal to update the frequency offset value of the transmission signal through an MAC CE signaling.

It should be noted that the network side device may periodically notify the terminal of updating the transmission signal frequency offset value of the terminal, or may notify the terminal of updating the transmission signal frequency offset value of the terminal when the network side device determines that the transmission signal frequency offset value of the terminal needs to be updated.

Because the network side device can send the sending signal updating frequency offset value to the terminal through the RRC signaling, and can also inform the terminal to update the sending signal frequency offset value through the RRC signaling, the sending signal updating frequency offset value can be arranged in the RRC signaling together with the sending signal frequency offset value, and the sending signal updating frequency offset value can also be arranged in the RRC signaling when the network side device informs the terminal to update the sending signal frequency offset value through the RRC signaling, namely, the terminal is informed to update the sending signal frequency offset value and send the sending signal updating frequency offset value through the same RRC signaling; the RRC signaling for informing the terminal to update the transmitted signal frequency offset value may be a single signaling.

Because the network side equipment can send the sending signal updating frequency offset value to the terminal through the MAC CE signaling and can also inform the terminal of updating the sending signal frequency offset value through the MAC CE signaling, the network side equipment can send the sending signal updating frequency offset value to the terminal through the MAC CE signaling and can inform the terminal of updating the sending signal frequency offset value through the same MAC CE signaling when the terminal is informed of updating the sending signal frequency offset value through the MAC CE signaling, namely, the terminal is informed of updating the sending signal frequency offset value and sending the sending signal updating frequency offset value to be sent in the same MAC CE signaling at the same time; the informing terminal to update the sending signal frequency offset value and sending the sending signal update frequency offset value can be in different MAC CE signaling, and different MAE CE signaling can be sent at the same time or not.

After the terminal receives the update frequency offset value of the transmission signal sent by the network side equipment and notifies the terminal to update the frequency offset value of the transmission signal, the terminal needs to update the mode when updating the frequency offset value of the transmission signal.

In the embodiment of the present invention, there are two update modes, a step update mode and an absolute value update mode, and the two update modes have different update frequency offset values of corresponding transmission signals, and the two update modes are described below separately.

The first mode and the step updating mode:

and when the updating mode is a stepping updating mode, the network side equipment takes the adjustment step value as the sending signal updating frequency offset value.

And after the network side equipment sends the adjustment step value as a sending signal updating frequency offset value to the terminal, the terminal adds the received sending signal updating frequency offset value to the current sending signal frequency offset value.

For example, if the current frequency offset value of the transmission signal of the terminal is 10KHZ, and the updated frequency offset value of the received transmission signal is 5KHZ, the adjusted frequency offset value of the transmission signal of the terminal is 15 KHZ.

It should be noted that, when the frequency offset value of the transmission signal of the terminal is updated in a step update manner, the update frequency offset value of the transmission signal may be a positive value or a negative value, and when the update frequency offset value of the transmission signal is a negative value, the terminal increases the update frequency offset value of the transmission signal on the frequency offset value of the current transmission signal, which actually reduces the frequency offset value of the current transmission signal of the terminal.

Mode two, absolute value update mode:

and when the updating mode is an absolute value updating mode, the network side equipment takes the target frequency offset value required to be adjusted as the sending signal updating frequency offset value.

And after the network side equipment sends the target frequency offset value to be adjusted to the terminal as the sending signal updating frequency offset value, the terminal takes the sending signal updating frequency offset value as the sending signal frequency offset value.

For example, if the updated frequency offset value of the transmission signal received by the terminal is 10KHZ, the adjusted frequency offset value of the transmission signal of the terminal is 10 KHZ.

In the embodiment of the present invention, the network side device may notify the terminal of the update mode through RRC signaling, or may notify the terminal of the update mode through MAC CE signaling.

In implementation, if the network side device notifies the terminal of the update mode, in order to save transmission resources, the update mode may be placed in RRC signaling configuring the pre-scheduled transmission parameters, or RRC signaling only with the update mode may be sent separately.

It should be noted that the RRC signaling for sending the update mode by the network side device may be placed in the RRC signaling for configuring the pre-scheduling resource scheduling mode for the terminal by the network side device, may be a separate RRC signaling, may be in the same RRC signaling as the RRC signaling for notifying the terminal to update the sending signal frequency offset value, and may be in the same RRC signaling as the RRC signaling for sending the sending signal update frequency offset value.

The MAC CE signaling for the network side device to send the update mode may be a single MAC CE signaling, may also be in the same MAC CE signaling as the MAC CE signaling for notifying the terminal to update the sending signal frequency offset value, and may also be in the same MAC CE signaling as the MAC CE signaling for sending the sending signal update frequency offset value.

The terminal receives the update frequency offset value of the sending signal, receives the update mode and receives the notification of the network side equipment to the terminal to update the frequency offset value of the sending signal, and the terminal updates the frequency offset value of the sending signal according to the update frequency offset value of the sending signal and the update mode.

It should be noted that, there is no specific order for the network side device to send the transmission signal update frequency offset value for adjusting the frequency offset during the non-orthogonal transmission of the terminal to the terminal, send the update mode, and notify the terminal to update the transmission signal frequency offset value for adjusting the frequency offset during the non-orthogonal transmission of the terminal.

In implementation, when the terminal updates the frequency offset value of the transmission signal of the terminal according to the update mode and the update frequency offset value of the transmission signal, since frequency offset exists between the terminals in the same time domain at present, in order to make the terminals in the same time domain not have frequency offset, the update frequency offset value and the update mode of the transmission signal sent to the terminal by the network side device may be different, as long as frequency offset does not exist between the terminals in the same time domain finally.

For ease of understanding, one aspect of the present invention is described below with reference to specific examples.

Configuring the pre-scheduled RRC signaling in TS38.331 as ConfiguredGrantConfig, adding a noma roffset field in the signaling, where the field contents are as follows:

in the normal _ carrier _ offset field, carrier _ offset indicates a transmission signal frequency offset value, maxnrofefseturnis indicates a maximum frequency offset value of a transmission signal, offset _ accumulation indicates an update mode, the update mode is a step update mode when offset _ accumulation is enabled, and the update mode is an absolute value update mode when offset _ accumulation is disabled.

and the terminal receives the Carrier Offset Update MAC CE signaling sent by the network side equipment, and updates the sending signal frequency Offset value of the terminal according to the updating mode indicated by the Offset Update field in the RRC signaling and the Offset Update in the Carrier Offset Update MAC CE signaling.

If the value of offsetacculation in the RRC signaling is enabled, the terminal adds a transmission signal update frequency offset value, namely carrieroffset, to the current transmission signal frequency offset value of the terminal_new＝carrieroffset_old+offsetupdate；

If the offset Accu in the RRC signalingWhen the value of the displacement is disabled, the terminal uses the received transmission signal update frequency offset value as the transmission signal frequency offset value of the terminal, namely carrieroffset_new＝offsetupdate。
