Description

Method and equipment for configuring and determining semi-persistent scheduling

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for configuring and determining semi-persistent scheduling.

Background

In order to reduce the overhead of control signaling, the LTE (Long Term Evolution) system introduces SPS (Semi-persistent scheduling) for services with substantially the same packet size and relatively regular arrival time intervals.

At present, an LTE system supports two scheduling modes: dynamic Scheduling and SPS (Semi-Persistent Scheduling). The dynamic scheduling is suitable for services with random service data arrival time or irregular data packet size; the SPS is mainly suitable for services with SPS periodicity reaching service data and relatively fixed packet size. For a traditional LTE system, SPS is mainly designed for voice service, and voice service is typically characterized by fixed arrival interval of data packets and basically fixed size of data packets, so that only one set of SPS configuration that SPS repeats periodically needs to be configured when SPS configuration is configured.

LTE Rel-14 introduced V2X (vehicle-to-anything) communication. V2X communication mainly contains three aspects:

V2V (Vechile-to-Vechile, car-to-car): communication between OBUs (On Board Unit) On the vehicle.

V2I (vehicle-to-Infrastructure): communication between the vehicle and an RSU (Road Side Unit).

V2P (vehicle-to-Pedestrian): communication between the vehicle and the pedestrian.

The V2V service is characterized in that a service data packet SPS period arrives (SPS period 100ms), but the size of the data packet is not basically fixed, the service data packet carrying the complete certificate is large, and the other data packets are small. Therefore, from the view of the service model, the V2V service model is a large packet followed by a plurality of small packets, then a large packet followed by a plurality of small packets, and the cycle is repeated. If the conventional LTE SPS approach is directly applied to V2V, if SPS configuration is allocated in large packets, there is inevitably a waste of resources for small packets transmitted using the SPS configuration; if the SPS configuration is allocated according to the small packet, the data of the large packet cannot be transmitted through the SPS configuration, and then an SR (Scheduling Request)/BSR (Buffer Status Reporting) Request is required to Request the base station to perform dynamic Scheduling. This increases the uplink/downlink overhead. Other V2X also have similar problems as V2V.

In summary, the LTE SPS method applied to the V2X communication method may cause resource waste or increase overhead.

Detailed Description

In the embodiment of the invention, Network side equipment informs a plurality of SPS C-RNTIs (Cell Radio Network Temporary identifiers) and SPS periods configured by the SPS corresponding to each SPS C-RNTI, and sends SPS frequency domain resource configuration information configured by the SPS corresponding to the SPS C-RNTI to a terminal by using a PDCCH (Physical Downlink Control Channel) signaling scrambled by the SPS C-RNTI. Because one SPS C-RNTI corresponds to one set of SPS configuration, compared with the background technology in which only one set of SPS configuration can be configured, the number of SPS configurations is increased, thereby reducing resource waste and expenditure; further improving system performance.

The network side equipment sends a plurality of sets of SPS configurations to the terminal, and the terminal determines the plurality of sets of SPS configurations configured by the network side equipment.

If the SPS configuration is the uplink SPS configuration, the terminal selects the SPS configuration required to be used by the terminal from the plurality of sets of SPS configurations, and sends data to the network side equipment through the SPS configuration required to be used by the terminal; correspondingly, if the network side device can determine the SPS used by the terminal, the network side device may detect the SPS used by the terminal, and if the SPS used by the terminal cannot be determined, the network side device needs to configure corresponding resource detection for multiple sets of SPS.

If the SPS configuration is downlink SPS configuration, the network side equipment selects SPS configuration required to be used by the terminal from the plurality of sets of SPS configuration, and sends data to the terminal through the SPS configuration required to be used by the terminal; correspondingly, if the terminal can determine the SPS used by the network side device, the terminal can detect the SPS used by the network side device, and if the SPS used by the network side device cannot be determined, the terminal needs to configure corresponding resource detection for multiple sets of SPS.

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.

As shown in fig. 1, a system for configuring semi-persistent scheduling according to an embodiment of the present invention includes:

the network side equipment 10 is used for informing a plurality of SPS C-RNTIs of the terminal and the SPS period configured by the SPS corresponding to each SPS C-RNTI, and sending SPS frequency domain resource configuration information configured by the SPS corresponding to the SPS C-RNTI to the terminal by using the PDCCH signaling scrambled by the SPS C-RNTI aiming at any one of the SPS C-RNTIs;

the terminal 20 is configured to determine a plurality of SPS C-RNTIs and SPS periods of SPS configurations of each SPS C-RNTI according to the notification of the network side device, where each SPS C-RNTI corresponds to a different SPS configuration; determining SPS frequency domain resource configuration information configured for each set of SPS configured by the terminal by the network side equipment according to PDCCH signaling scrambled by each SPS C-RNTI in the plurality of SPS C-RNTIs; and determining a plurality of sets of SPS configurations configured for the terminal by the network side equipment according to the SPS frequency domain resource configuration information and the SPS period configured by each set of SPS.

When the network side equipment configures a plurality of sets of SPS configured for the terminal, the method comprises the step of configuring SPS frequency domain resource configuration information and SPS periods corresponding to the plurality of sets of SPS configured for the terminal.

When the SPS period is configured for the terminal, there are two ways for the present invention, which are described below.

In the first mode, an SPS period is configured for the terminal through an RRC (Radio Resource Control) signaling.

Specifically, the network side device places all SPS C-RNTIs and SPS periods configured by SPS corresponding to each SPS C-RNTI in one RRC signaling and sends the RRC signaling to the terminal;

correspondingly, the terminal takes all SPS C-RNTIs in the received RRC signaling as SPS C-RNTIs of the same service, and determines the SPS period of the SPS configuration corresponding to each SPS C-RNTI in the RRC signaling.

For example, the SPS C-RNTI corresponding to one service is A, B and C, a corresponds to SPS period 1 of SPS configuration, B corresponds to SPS period 2 of SPS configuration, and C corresponds to SPS period 3 of SPS configuration.

The network side equipment places the binding relationship between the A and the SPS period 1, the binding relationship between the B and the SPS period 2, and the binding relationship between the C and the SPS period 3 in an RRC signaling;

correspondingly, after the terminal receives an RRC signaling, since the RRC signaling includes A, B and C, the terminal determines that A, B and C belong to the same service, and according to the binding relationship in the RRC signaling, it can determine that a corresponds to SPS period 1 configured by SPS, B corresponds to SPS period 2 configured by SPS, and C corresponds to SPS period 3 configured by SPS.

And in the second mode, the SPS period is configured for the terminal through a plurality of RRC signaling.

Specifically, for any one SPS C-RNTI in the SPS C-RNTIs, the network side device places the SPS C-RNTI and an SPS period configured by the SPS corresponding to the SPS C-RNTI in an RRC signaling and sends the SPS period to the terminal, wherein different SPS C-RNTIs are located in different RRC signaling;

optionally, as for the second mode, the network side device carries the same identifier information in all RRC signaling including any one of the SPS C-RNTIs.

Correspondingly, the terminal determines a plurality of received RRC signaling containing the same identification information, each SPS C-RNTI in the plurality of RRC signaling containing the same identification information is used as an SPS C-RNTI of the same service, and an SPS period in each RRC signaling is used as an SPS period of SPS configuration corresponding to the SPS C-RNTI in the RRC signaling.

For example, the SPS C-RNTI corresponding to one service is A, B and C, a corresponds to SPS period 1 configured by SPS, B corresponds to SPS period 2 configured by SPS, C corresponds to SPS period 3 configured by SPS, and the identification information of the service is 11.

The network side device places A, SPS cycles 1 and 11 in RRC signaling 1; b, SPS periods 2 and 11 are placed in RRC Signaling 2; c, SPS periods 3 and 11 are placed in RRC Signaling 1.

After the terminal receives the RRC signaling 1, the RRC signaling 2 and the RRC signaling 3, since the identification information included in the RRC signaling 1, the RRC signaling 2 and the RRC signaling 3 is 11, it can be determined that SPS C-RNTIs included in the RRC signaling 1, the RRC signaling 2 and the RRC signaling 3 correspond to the same service, and the RRC signaling 1 includes a and an SPS period 1, and it can be determined that a corresponds to the SPS period 1 configured by the SPS; the RRC signaling 2 comprises B and SPS period 2, and the SPS period 2 configured by the SPS corresponding to the B can be determined; c and SPS period 3 are included in RRC signaling 3, and it may be determined that C corresponds to SPS period 3 of the SPS configuration.

When the SPS frequency domain resource configuration information is configured for the terminal, the SPS frequency domain resource configuration information is configured for the terminal through the PDCCH signaling.

Specifically, the network side device places SPS frequency domain resource configuration information configured by one SPS in a PDCCH signaling, and scrambles the PDCCH signaling by using an SPS C-RNTI corresponding to the SPS configuration.

The SPS frequency domain resource configuration information configured by each SPS adopts the above manner, that is, one PDCCH signaling includes one SPS frequency domain resource configuration information.

Correspondingly, after receiving the scrambled PDCCH information, the terminal can determine which service corresponds to the SPS frequency domain resource configuration information included in the PDCCH information and which SPS period is a group according to the SPS C-RNTI, so that a set of SPS configuration can be determined according to the SPS period and the SPS frequency domain resource configuration information in the same group.

For example, the SPS C-RNTI corresponding to one service is A, B and C, a corresponds to SPS period 1 and SPS frequency domain resource configuration information 1 configured by SPS, B corresponds to SPS period 2 and SPS frequency domain resource configuration information 2 configured by SPS, and C corresponds to SPS period 3 and SPS frequency domain resource configuration information 3 configured by SPS.

The network side equipment scrambles the PDCCH signaling 1 containing the SPS frequency domain resource configuration information 1 by using SPS C-RNTIA; scrambling PDCCH signaling 2 containing SPS frequency domain resource configuration information 2 by using SPS C-RNTIB; and scrambling the PDCCH signaling 3 containing the SPS frequency domain resource configuration information 3 by using SPS C-RNTIB.

Correspondingly, after receiving the PDCCH signaling 1 scrambled by the SPS C-RNTIA, the terminal knows the SPS frequency domain resource configuration information 1 in the PDCCH signaling 1 corresponding to the SPS C-RNTIA, and knows that the SPS C-RNTIA corresponds to the SPS period 1 after receiving the RRC signaling, so that the SPS frequency domain resource configuration information 1 and the SPS period 1 are a group;

after receiving the PDCCH signaling 2 scrambled by the SPS C-RNTIB, the terminal knows that the SPS C-RNTIB corresponds to the SPS frequency domain resource configuration information 2 in the PDCCH signaling 2, and knows that the SPS C-RNTIB corresponds to the SPS period 2 after receiving the RRC signaling, so that the SPS frequency domain resource configuration information 2 and the SPS period 2 are known to be a group;

after receiving the PDCCH signaling 3 scrambled by the SPS C-RNTIC, the terminal knows that the SPS C-RNTIC corresponds to the SPS frequency domain resource configuration information 3 in the PDCCH signaling 3, and knows that the SPS C-RNTIC corresponds to the SPS period 3 after receiving the RRC signaling, so that the SPS frequency domain resource configuration information 3 and the SPS period 3 are a group.

Optionally, in order to ensure that the terminal uses the determined SPS configuration when performing a service, the network side device may determine a sending time of each PDCCH signaling according to the service characteristics of the service;

and aiming at any one SPS C-RNTI in the plurality of SPS C-RNTIs, the network side equipment sends the PDCCH signaling which is scrambled by each SPS C-RNTI and contains the SPS frequency domain resource configuration information after the corresponding sending time arrives.

The service features of the embodiment of the present invention include, but are not limited to, part or all of the following information: time of arrival of a packet, packet size.

For example, in fig. 2A, a service is characterized in that a period includes 1 big packet and 4 small packets, each data packet is separated by 100ms, and if the service is scheduled from a subframe n, PDCCH signaling for activating a big packet SPS resource is sent in the subframe n; PDCCH signaling for small packet SPS resource activation is sent in subframe structure n + 100.

Yet another way is to add a time domain offset k to the PDCCH signaling, in which case the PDCCH transmission time is n, and then the SPS resource activation time is n + k. Corresponding to the service, two PDCCH signals are simultaneously sent at the moment n, the time domain offset corresponding to one PDCCH signal is measured by k, and the time domain offset corresponding to the other PDCCH signal is measured by k + 100.

The above describes that the network side device configures multiple sets of SPS configurations for the terminal.

After configuration, service transmission can be performed according to the SPS configuration.

If the SPS configuration is the uplink SPS configuration, the network side equipment is a sending end; the terminal is a receiving end;

if the SPS configuration is the downlink SPS configuration, the network side equipment is a receiving end; the terminal is the transmitting end.

Wherein, for a transmitting end, SPS configuration which needs to be used by service needs to be selected from a plurality of sets of SPS configuration;

accordingly, if the receiving end can predict the SPS configuration (e.g., based on information such as a service model) that needs to be used by the service selected by the transmitting end from the plurality of sets of SPS configurations, the receiving end can perform SPS data reception according to the SPS configuration that needs to be used by the predicted service. Otherwise, multiple sets of SPS resources need to be blindly detected.

Except for the mode of prediction of the receiving end, if the transmitting end and the receiving end agree on the specific selection condition, the receiving end can agree on the SPS configuration which needs to be used by the service selected by the specific selection condition transmitting end from the plurality of sets of SPS configurations, and directly detect the SPS configuration which needs to be used by the service.

Optionally, when the sending end selects the SPS configuration that needs to be used by the service from the multiple sets of SPS configurations:

Optionally, the selection condition is one of the following conditions:

selecting a largest SPS frequency domain resource block;

selecting a minimum SPS frequency domain resource block;

Taking V2V as an example, assuming that the sending end has two sets of SPS configurations for the same service, the sending end determines the SPS frequency domain resources with overlapped time domains according to the maximum SPS frequency domain resource block, and then the SPS frequency domain resources finally determined by the sending end are as shown in fig. 2B.

The SPS frequency domain resources of the T1 position and the T1+500ms position overlap, SPS configuration 2 is selected according to the largest SPS frequency domain resource block, and SPS frequency domain resources which can be used are selected because other positions do not overlap.

If determined in terms of the smallest SPS frequency domain resource block, then in fig. 2B, the T1 location and the T1+500ms location SPS frequency domain resources overlap, requiring SPS configuration 1 to be selected.

If the SPS frequency domain resource block is selected according to the data to be transmitted, selecting the SPS frequency domain resource block not smaller than the data to be transmitted according to the size of the data to be transmitted, for example, in fig. 2B, the SPS frequency domain resource block at the T1 position overlaps with the SPS frequency domain resource at the T1+500ms position, and if the SPS configuration 1 is selected, the SPS configuration 1 is selected; SPS configuration 2 is selected if SPS configuration 1 is not capable of transmitting data that needs to be transmitted and SPS configuration 2 is capable of transmitting data that needs to be transmitted.

Optionally, after configuring multiple sets of SPS configurations for the terminal, the network side device may also release multiple sets of SPS configurations when the SPS configurations need to be released (there are many triggering conditions for releasing the SPS configurations, such as that corresponding services are completed, and services need to be stopped).

The embodiment of the invention provides two release modes of implicit release and explicit release, which are respectively introduced below.

First, implicit release mode.

If the SPS configuration is the uplink SPS configuration, for each set of SPS configuration, the terminal sends, to the network side device, N consecutive padding BSRs (Buffer status report) without data parts through the SPS configured resources, which are used to notify the network side device to release the SPS configuration;

correspondingly, for each set of SPS configuration, if the network side device receives N consecutive padding BSRs without data parts through the frequency domain resource corresponding to the SPS configuration, the network side device releases the SPS configuration for the terminal.

And II, an explicit release mode.

The network side device simultaneously or non-simultaneously utilizes the PDCCH signaling scrambled by each SPS C-RNTI to notify the terminal to release the SPS configuration corresponding to the SPS C-RNTI (for example, a certain (or some) field(s) in the PDCCH signaling takes a special value to indicate that the PDCCH signaling is the PDCCH signaling for release).

step 801, the terminal determines SPS frequency domain resource configuration information configured for each set of SPS configured by the terminal by the network side equipment according to a PDCCH signaling scrambled by each SPS C-RNTI in a plurality of SPS C-RNTIs;

and step 802, the terminal determines a plurality of sets of SPS configurations configured for the terminal by the network side equipment according to the SPS frequency domain resource configuration information and the SPS period configured by each set of SPS.

Optionally, the selection condition is one of the following conditions:

selecting a largest SPS frequency domain resource block;

selecting a minimum SPS frequency domain resource block;

The embodiments of the present invention will be described in detail below with reference to several examples.

Example 1: the association relationship between a plurality of SPS C-RNTIs of one service is informed through one RRC signaling.

Step 1: the base station determines a plurality of SPS C-RNTIs aiming at the same service and informs the terminal through RRC signaling.

Aiming at the same SPS service, when the base station needs to configure a plurality of sets of SPS frequency domain resources with different sizes, the base station can inform the terminal that the SPS C-RNTI in the RRC signaling is directed to the same service by carrying a plurality of SPS C-RNTIs and the SPS period corresponding to each SPS C-RNTI in one RRC signaling. The number N of SPS C-RNTIs depends on the number of SPS frequency domain resource blocks with different sizes to be allocated for one SPS service.

Taking the V2V service as an example, for the V2V service, since it supports two packets with different sizes, the service packet arrival is according to 1-size packet and 4-size packet, and each packet arrives at a pattern of 100 ms. Then, the RRC signaling sent by the base station may carry 2 SPS C-RNTIs, where a period corresponding to one SPS C-RNTI is 500ms, and a period corresponding to one SPS C-RNTI is 100 ms.

Of course, the RRC signaling for configuring the SPS frequency domain resource may also carry other parameters, such as HARQ process and other parameters. The contents contained in the specific RRC signaling and the meaning of each parameter are exemplified in tables 1 and 2 below. It is noted that the parameters listed in the following table may be combined into one parameter if the values are the same for different SPS C-RNTIs, to save signaling overhead.

Table 1 contents included in RRC signaling configuring downlink SPS

Table 2 contents included in RRC signaling configuring uplink SPS

Step 2: the base station sends PDCCH signaling for SPS activation.

And the base station respectively utilizes the PDCCH scrambled by the SPS C-RNTI corresponding to the same service which is notified to the terminal to activate a plurality of SPS frequency domain resources with different sizes for the terminal. Namely, the base station places the SPS frequency domain resource configuration information in the PDCCH signaling and scrambles the SPS frequency domain resource configuration information through the corresponding SPS C-RNTI.

When the base station sends the PDCCH, the PDCCH signaling sending time activated by different SPS frequency domain resources of the same service needs to be matched with the service characteristics.

Taking the V2V service as an example, for the V2V service, since it supports two packets with different sizes, the service packet arrival is according to 1-size packet and 4-size packet, and each packet arrives at a pattern of 100 ms. Then, the base station sends PDCCH signaling for SPS frequency domain resource activation for packet and packet transmission, and according to the scheduling timing relationship, the activated SPS frequency domain resources need to be overlapped in time domain every 500ms, as shown in fig. 2A:

and step 3: the terminal determines a plurality of sets of SPS configurations.

The terminal determines that all SPS frequency domain resources scheduled by all SPS C-RNTIs contained in one RRC signaling are for the same service according to the content of the RRC signaling (the determined action may occur between step 1 and step 2).

And the terminal determines the SPS frequency domain resource position corresponding to each SPS C-RNTI according to the SPS frequency domain resource configuration information in the PDCCH signaling scrambled by each SPS C-RNTI included in the RRC signaling.

For example, if the SPS frequency domain resource configuration information a and the SPS frequency domain resource configuration information B exist, it is assumed that the SPS C-RNTI included in the RRC signaling is XX and YY, respectively, and the RRC signaling further includes SPS period 1 corresponding to XX and SPS period 2 corresponding to YY.

Since XX and YY are in one RRC, the terminal knows XX and YY are for the same service.

The PDCCH signaling scrambled by XX is assumed to include SPS frequency domain resource configuration information A; and the PDCCH signaling scrambled by YY comprises SPS frequency domain resource configuration information B, and the terminal determines that SPS frequency domain resource configuration information A and XX correspond to the same set of SPS configuration corresponding to SPS period 1 and SPS frequency domain resource configuration information B and YY correspond to SPS period 2 and the same set of SPS configuration.

And the terminal determines one set of SPS configuration according to the SPS period 1 and the SPS frequency domain resource configuration information A, and determines the other set of SPS configuration according to the SPS period 1 and the SPS frequency domain resource configuration information B.

When the network side device needs to perform service transmission with the terminal, it may also determine a plurality of sets of SPS configurations configured for the terminal. The network side device determines the manner of configuring multiple sets of SPS for the terminal, and may refer to step 3. Since the plurality of sets of SPS configurations are configured by the network side device for the terminal, the network side device may also determine which SPS configurations correspond to the terminal directly from the plurality of sets of SPS configurations.

It should be noted that there are many ways for the network side device to determine multiple sets of SPS configurations, which are just examples, and any way that enables the network side device to determine multiple sets of SPS configurations is applicable to the embodiment of the present invention.

And 4, step 4: and the transmitting end determines the SPS configuration needed to be used by the service from the plurality of sets of SPS configurations.

If the service is an uplink service, the sending end is a terminal, and the receiving end is a base station; if the service is downlink service, the transmitting end is a base station and the receiving end is a terminal.

If the plurality of sets of SPS configurations are not overlapped in the time domain, the transmitting end takes all the configured SPS frequency domain resources as the SPS frequency domain resources which can be used by the transmitting end.

If the plurality of sets of SPS configurations have overlap in the time domain, the sending end determines to select the specifically used SPS frequency domain resources at the time domain overlapping position according to one of the following rules, wherein the rule can be pre-configured or informed by the base station.

The largest SPS frequency domain resource block is always selected.

And selecting the corresponding SPS frequency domain resource block according to the actual data transmission requirement.

The smallest SPS frequency domain resource block is always selected.

Specifically, taking V2V as an example, assuming that the sending end has two sets of SPS configurations for the same service, the sending end determines, for SPS frequency domain resources with overlapping time domains, according to the maximum SPS frequency domain resource block, and then the SPS frequency domain resources finally determined by the sending end are as shown in fig. 2B.

And 5: and detecting SPS by the receiving end.

If a plurality of sets of SPS configurations are overlapped on a time domain, and a receiving end (a downlink finger base station; an uplink finger terminal) determines to select the specifically used SPS frequency domain resources at the time domain overlapping position according to the following rules: and selecting the corresponding SPS frequency domain resource block according to the actual data transmission requirement.

If the receiving end can predict the size of the SPS frequency domain resource block used by the transmitting end (for example, according to information such as a traffic model), the receiving end can receive SPS data according to the size of the SPS frequency domain resource block used by the predicted terminal. Otherwise, multiple sets of SPS configurations need to be detected blindly.

If the sending end can select the SPS frequency domain resources to be used specifically at the time domain overlapping position, the receiving end determines the SPS frequency domain resources to be used by the sending end, and the SPS frequency domain resources are directly detected.

Step 6: and releasing SPS frequency domain resources aiming at the same service.

The release of different SPS frequency domain resources for the same service can be carried out simultaneously or not. Namely:

for the uplink:

implicit release: different SPS frequency domain resources aiming at the same SPS service can implicitly release the uplink SPS frequency domain resources by respectively sending N continuous padding BSRs without data parts.

And (3) display release: and the base station simultaneously or non-simultaneously uses the PDCCH scrambled by different SPS C-RNTIs to respectively release the uplink SPS frequency domain resources corresponding to each SPS C-RNTI.

The downlink only supports an explicit release mode, and the base station simultaneously or non-simultaneously uses PDCCH scrambled by different SPS C-RNTIs to respectively release downlink SPS frequency domain resources corresponding to the SPS C-RNTIs.

Example 2: the association relationship between a plurality of SPS C-RNTIs of one service is informed through a plurality of RRC signaling.

For the same SPS service, when a base station needs to configure a plurality of sets of SPS frequency domain resource blocks with different sizes for a terminal, the base station respectively sends RRC signaling for SPS configuration aiming at each set of SPS frequency domain resource. Each RRC signaling for SPS configuration only carries one SPS C-RNTI and an SPS frequency domain resource period corresponding to the SPS C-RNTI, and meanwhile, identification information is added in the RRC signaling. The size of the identification information is M bit, and the value of M depends on the number of SPS services which can be simultaneously supported by the terminal. For example, if the number of SPS services that a terminal can support is 4, M needs 2 bits, and 00, 01, 10, and 11 correspond to 4 services, respectively.

After the identification information is added to the SPS configured RRC signaling, the contents included in the signaling are shown in tables 3 and 4 below.

Table 3 contents included in RRC signaling configuring downlink SPS

Table 4 contents included in RRC signaling configuring uplink SPS

		semiPersistSchedC-RNTI	C-RNTI for SPS scheduling

		p0-UE-PUSCH-Persistent	Related parameters for uplink power control
twoIntervalsConfig	Whether or not to use multimode SPS (only for TDD systems)
		ServiceIndentifier	Service identification

Step 2: the base station sends PDCCH signaling for SPS activation.

Taking the V2V service as an example, for the V2V service, since it supports two packets with different sizes, the service packet arrival is according to 1-size packet and 4-size packet, and each packet arrives at a pattern of 100 ms. Then, the base station sends PDCCH signaling for SPS frequency domain resource activation for packet and packet transmission, and according to the scheduling timing relationship, the activated SPS frequency domain resources need to be overlapped in time domain every 500ms, as shown in fig. 2A.

And step 3: the terminal determines a plurality of sets of SPS configurations.

And the terminal determines the SPS frequency domain resource position corresponding to each SPS C-RNTI according to SPS frequency domain resource configuration information in the PDCCH signaling scrambled by the SPS C-RNTI in each RRC signaling, and determines which SPS frequency domain resource configuration information belongs to the same service and which SPS C-RNTI belongs to the same service according to the identification information included in each RRC signaling.

If SPS frequency domain resource configuration information a and SPS frequency domain resource configuration information B exist, assume that SPS C-RNTI included in RRC signaling a is XX, and SPS period 1, and identification information is 00; the SPS C-RNTI in the RRC signaling B is YY corresponding to the SPS period 21, and the identification information is 00.

Since the identification information in the RRC signaling a is the same as the identification information in the RRC signaling B, the terminal determines that XX and YY belong to the same service.

The largest SPS frequency domain resource block is always selected.

The smallest SPS frequency domain resource block is always selected.

And 5: and detecting SPS by the receiving end.
