The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network device 12, where the terminal 11 may be a User Equipment (UE) or other terminal-side devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device).

In addition, the network device 12 may be a Master Node (MN) or a Secondary Node (SN). It should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the network device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of an SPS transmission method according to an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 2, the SPS transmission method includes the following steps:

step 201, receiving a first downlink control message, where the first downlink control message is used to indicate a transmission period of the SPS transmission.

This step may be receiving the first downlink control message sent by the network device.

The first downlink control message may indicate a transmission period of the SPS transmission, where the first downlink control message informs the terminal of the transmission period used (or corresponding) for the SPS transmission, so that the terminal may perform the SPS transmission according to the indicated transmission period. The first downlink control message may be an active downlink control message, where the active downlink control message is used to activate an inactive SPS transmission and indicate a transmission period of the SPS transmission, or the first downlink control message may be a downlink control message used to adjust a transmission period of an active SPS transmission.

It should be noted that, the first downlink control message is not limited to indicate only the transmission period, and in the embodiment of the present invention, the first downlink control message may also indicate other information, for example: HARQ process number or HARQ-ACK feedback resource.

And step 202, performing the SPS transmission according to the transmission period.

And after receiving the downlink control message, the terminal determines the transmission period of the SPS, so that the SPS transmission is carried out according to the determined transmission period.

The SPS transmission may be uplink SPS transmission, that is, the terminal sends data to the network device by using SPS transmission, or the SPS transmission may be downlink SPS transmission, that is, the terminal receives data sent by the network device by using SPS transmission.

The transmission period of the terminal can be flexibly indicated through the steps, so that compared with the situation that the terminal can only transmit according to the preset transmission period, the transmission performance of the terminal can be improved.

In addition, the transmission cycle indicated by the first downlink control message may be determined by the network device according to a service, where different services may correspond to different transmission cycles, so that the transmission cycle corresponding to the current service of the terminal may be indicated by the first downlink control message, and an effect of saving power consumption of the terminal may be achieved, for example: if the transmission interval of a certain service is 20ms, the indicated transmission period is 20ms, so that unnecessary monitoring by the terminal can be avoided, and the power consumption of the terminal can be saved.

As an optional implementation, the first downlink control message includes:

downlink Control Information (DCI) or a Media Access Control Element (MAC CE).

The DCI may be an activation DCI activating the SPS transmission, so that the DCI may activate the SPS transmission of the terminal and indicate a transmission period of the SPS transmission, thereby saving resource transmission overhead.

Of course, in the embodiment of the present invention, the DCI is not limited to the activation DCI, and for example: other DCI may also be used, for example, a reactivation or adjustment DCI for SPS transmission that is activated by the terminal, and specifically, the transmission period of the SPS transmission may be adjusted by the DCI.

This embodiment may enable indicating the transmission period of SPS through DCI or MAC CE. Of course, the embodiment of the present invention does not limit the transmission period of SPS indicated by DCI or MAC CE, for example: the transmission period may be indicated by other downlink control messages.

As an optional implementation manner, the terminal presets at least two SPS transmission periods, and the first downlink control message includes transmission period identification information, where the transmission period identification information is used to indicate one of the at least two SPS transmission periods.

The presetting of at least two SPS transmission periods may be understood as that the terminal is preset with at least two SPS transmission periods in advance. Preferably, the preset at least two SPS transmission periods are defined by a protocol or configured by higher layer signaling. The configuration of the high-level signaling may be that the network device configures the terminal through the high-level signaling.

The period identification information may be a number of a transmission period, for example: if the at least two SPS transmission periods are a set of preset SPS periods, the network device may indicate numbers in the set through the first downlink control message to indicate transmission periods of SPS transmissions.

In this embodiment, at least two SPS transmission periods are preset, so that the corresponding transmission period can be flexibly indicated by the first downlink control message, thereby avoiding unnecessary monitoring or transmission by the terminal and achieving the effect of saving the power consumption of the terminal.

For example: the network configures a set S ═ P1, P2, P3, P4} of Downlink (DL)/Uplink (UL) SPS periods to the terminal through Radio Resource Control (RRC) signaling, and configures other parameters for DL SPS transmission to the terminal. The network activates DL/UL SPS transmission configured by the terminal through DCI, wherein the activated DCI comprises a 2-bit period indication field. The mapping relationship can be as shown in table 1:

table 1:

numbering	Period of time
		00	The first cycle of the RRC configured set of cycles, i.e., P1
01	The second cycle of the RRC configured set of cycles, i.e., P2
		10	The third cycle of the RRC configured set of cycles, i.e., P3
11	The fourth cycle of the RRC configured set of cycles, i.e., P4

Specifically, the network indicates in the activation DCI 1 that the transmission period of the DL/UL SPS activated by the terminal is P1. When the type of the downlink traffic changes, the arrival interval of the data packets may change, for example, the interval becomes larger. At this time, the network device may adjust the interval of DL/UL SPS transmission of the terminal to a larger interval, so that the terminal does not need to monitor downlink data according to a shorter period. The network device indicates that the transmission period of the terminal-activated DL/UL SPS is adjusted to P2 by transmitting DCI 2. In this example, the network may adjust only the DL/UL SPS transmission period activated by the terminal in DCI 2, but is not limited thereto, and may adjust parameters of other transmissions, for example.

As an optional implementation manner, the terminal presets at least two sets of SPS resource configurations, where each set of SPS resource configuration includes an SPS transmission period, the first downlink control message includes activation resource identification information, the activation resource identification information is used to indicate that an SPS resource configuration corresponding to the activation resource identification information in the at least two sets of SPS resource configurations is activated, and an SPS transmission period included in the SPS resource configuration corresponding to the activation resource identification information is a transmission period of the SPS transmission.

The SPS transmission period may be a transmission period configured for SPS transmission, and the transmission period of SPS transmission may refer to a transmission period used by the first downlink control message to indicate the SPS transmission, that is, to indicate the SPS transmission to use the SPS transmission period in the SPS resource configuration corresponding to the activated resource identifier information.

In this embodiment, the SPS resource configuration may be a transmission parameter configuration of SPS transmission, which may include parameters such as SPS transmission period, HARQ process number, and the like. In addition, at least one parameter in each set of resource allocation is different, for example: SPS transmission periods are different, etc.

In addition, the preset at least two sets of SPS resource configurations may be defined by a protocol or configured by higher layer signaling.

In this embodiment, at least two SPS resource configurations are preset, so that the corresponding SPS resource configurations can be flexibly indicated by the first downlink control message, thereby avoiding unnecessary monitoring or transmission by the terminal and achieving the effect of saving the power consumption of the terminal.

Optionally, in this embodiment, multiple SPS resource configurations of the at least two sets of SPS resource configurations are in an active state at the same time.

In the embodiment, the plurality of SPS resource configurations can be simultaneously in the activated state, so that the SPS resource configuration terminals in the activated state can all use the SPS resource configurations, and the terminals can flexibly select the corresponding SPS resource configurations according to needs so as to improve the communication performance of the terminals. Preferably, the simultaneous activation of the plurality of sets of SPS resource configurations may be indicated in the first downlink control message, or may also be preset.

Optionally, in the foregoing embodiment, after receiving the first downlink control message, the method further includes:

receiving a second downlink control message, wherein the second downlink control message is used for deactivating at least one of the SPS resource configurations in the activated state.

The second downlink control message may be DCI or MAC CE.

And deactivating through the second downlink control message instruction, so that the resource state of the terminal SPS resource configuration can be updated, and the communication performance of the terminal is improved.

Further, the second downlink control message may be configured to indicate at least one piece of deactivation resource identification information, where the at least one piece of deactivation resource identification information is used to indicate to deactivate SPS resource configuration corresponding to the at least one piece of deactivation resource identification information.

Since the SPS resource configuration is deactivated through the deactivation resource identification information, the signaling overhead can be saved.

The following specific embodiment exemplifies an implementation manner in which the terminal is preset with at least two sets of SPS resource configurations:

the network device configures a plurality of DL SPS resource configurations to the terminal through RRC signaling, wherein { DL SPS configuration 1, DL SPS configuration 2, DL SPS configuration 3 and DL SPS configuration 4} are configured, and at least one transmission parameter of each DL SPS configuration is different. In this example, the transmission periods of different DL SPS configurations are different, and are { DL SPS configuration 1 (period P1), DL SPS configuration 2 (period P2), DL SPS configuration 3 (period P3), and DL SPS configuration 4 (period P4) }. Each DL SPS configuration is numbered separately. The mapping relationship can be as shown in table 2:

TABLE 2

The network device activates the corresponding DL SPS configuration, for example, activates DL SPS configuration 1, by activating DCI 1, indicating the number of the activated DL SPS configuration. Thereafter, when the type of the downlink traffic changes, the arrival interval of the data packets may change, for example, the interval becomes larger. At this time, the network device may adjust the interval of DL SPS transmission of the terminal to a larger interval, so that the terminal does not need to monitor downlink data according to a shorter period. The network device adjusts the transmission period to P2 by transmitting an active DCI 2 indicating the terminal activated DL SPS configuration 2. In this example, the network device may also indicate the transmission parameters of the DL SPS activated by the terminal in the DCI, but is not limited thereto, and for example, other transmission parameters may not be adjusted in different activated DCIs.

As an optional implementation manner, the first downlink control message includes an indication field, and the indication field is used for indicating a transmission period of the SPS transmission.

Wherein the indication field may explicitly indicate a transmission period of the SPS transmission, for example: the indication field includes indication information of a transmission period; or the above indication field may implicitly indicate the transmission period of the SPS transmission, for example: the indication field may be used to indicate a transmission period adjustment magnitude to implicitly indicate a transmission period of the SPS transmission by the transmission period adjustment magnitude.

Since the multiple transmission cycles may not be preset in this embodiment, it may be realized more simply.

In an implementation manner, a transmission period range is preset in the terminal, and the transmission period indicated by the indication field is a transmission period within the transmission period range.

The transmission period range may be a maximum transmission period and a minimum transmission period, that is, the transmission period range may be composed of a maximum transmission period and a minimum transmission period.

This implementation can indicate or adjust the periodicity of SPS transmissions with less granularity, and can indicate more periodicity given a particular transmission periodicity range.

Preferably, the terminal presets a transmission period indication granularity, and the transmission period indicated by the indication field is one of at least two transmission periods determined according to the transmission period indication granularity within the transmission period range.

When the transmission period indication granularity is preset and the transmission period range is used, the terminal may divide the transmission period range into a plurality of transmission periods according to the transmission period indication granularity. Thus, when the granularity is adjusted to be smaller, the transmission cycle can be indicated with finer granularity, and when the granularity is adjusted to be larger, the signaling overhead can be reduced.

For example: the network device configures the terminal with a transmission period of DL SPS through RRC signaling in a range of [ minimum transmission period (Pmin), maximum transmission period (Pmax) ], where DCI indicates DL SPS transmission period indication granularity (alternatively referred to as transmission period granularity) may be configured or predefined by the network, e.g., Pstep denotes transmission period indication granularity. A field of N-bit is included in the DCI to indicate an actual transmission period of the DL SPS, where N ═ ceil (log2 ((Pmax-Pmin)/Pstep)), where ceil denotes a function that returns a minimum integer greater than or equal to a specified expression.

The network device simultaneously indicates a transmission period of the DL SPS in the DCI when activating the DL SPS.

Specifically, the network device indicates in the activation DCI 1 that the transmission period of the DL SPS activated by the terminal is P1. When the type of the downlink traffic changes, the arrival interval of the data packets may change, for example, the interval becomes larger. At this time, the network device may adjust the interval of DL SPS transmission of the terminal to a larger interval, so that the terminal does not need to monitor downlink data according to a shorter period. The network device indicates that the transmission period of the DL SPS activated by the terminal is adjusted to P2 by transmitting DCI 2.

In another implementation, the indication field is used to indicate a transmission period adjustment magnitude by which a transmission period of the SPS transmission is implicitly indicated.

This may enable implicitly indicating the transmission periodicity of the SPS transmissions.

When the terminal receives the first downlink control message, the transmission period required to be adjusted by the terminal can be determined according to the transmission period adjustment amplitude and the transmission period used by the current terminal, and the transmission period of the terminal can be adjusted flexibly.

For example: the terminal may preset at least two transmission period adjustment ranges, the indication field includes transmission period adjustment range identification information, and the transmission period adjustment range identification information is used to indicate one of the at least two transmission period adjustment ranges.

The preset adjustment amplitude of at least two transmission periods can be defined by a protocol or configured by a high-level signaling.

It should be noted that, in the embodiments of the present invention, the transmission period of the SPS transmission of the terminal and other parameters may be activated and/or adjusted in various ways, so that the power consumption of the terminal may be reduced. For example: the network device may adjust a period corresponding to SPS transmission of the terminal according to the type of the service and the arrival interval, so as to reduce power consumption of the terminal.

For example: when the network configures DL/UL SPS transmission to the terminal, the terminal can implement SPS transmission/reception according to different periods by the following method.

The first method is as follows: presetting a set of SPS periods, and indicating the transmission period of SPS transmission by the network equipment through activating a DCI or MAC CE to indicate a number in the set;

if the terminal has configured and activated the SPS, the network device may adjust the SPS that the terminal has activated to the indicated transmission period by sending DCI or MAC CE to indicate the adjusted SPS transmission period;

the set of preset SPS periods may be predefined or configured by higher layer signaling.

The second method comprises the following steps: the high-level signaling configures a plurality of SPS resource configurations, and the network equipment indicates the activated SPS resource configurations by activating DCI or MAC CE;

if the terminal has configured and activated the SPS resource configuration 1, the network device may adjust the SPS resource configuration of the terminal to the indicated SPS resource configuration by sending an activation DCI or MAC CE to indicate the adjusted activated SPS resource configuration number;

the terminal can be in an active state simultaneously with a plurality of SPS resource configurations;

the network device may also transmit a deactivation DCI or MAC CE indicating the SPS resource configuration that needs to be deactivated.

The third method comprises the following steps: the network equipment indicates the transmission period of the SPS configured by the terminal through DCI or MAC CE;

for example, the activation DCI includes a field for indicating a transmission period of the DL SPS configured by the terminal;

the network device may configure the maximum and minimum periodicity of the SPS, with the actual transmission periodicity indicated by the DCI or MAC CE.

For example, a Voice over Internet Protocol (VoIP) device transmits Voice packets within a period of time with an interval of 20ms and a packet size of 40bytes, and transmits Silence Insertion Description (SID) packets (e.g., background noise) within another period of time with an interval of 160ms and a packet size of 15 bytes; therefore, the network device may determine whether to change the period according to a change in packet size, or a Quality of Service (QoS) requirement of the Service, or other indicators.

In the embodiment of the invention, a first downlink control message is received, wherein the first downlink control message is at least used for indicating the transmission period of SPS transmission; and performing the SPS transmission according to the transmission period. The embodiment of the invention can improve the transmission performance of the terminal.
