Background technique

The standard protocol specified by the 3rd Generation Partnership Project (3GPP) specifies the transmission of data (such as uplink data or downlink data). Among them, in data transmission, the following implementation methods can exist:

One is that the network can dynamically schedule resources and transmit data through dynamically scheduled resources. However, in order to transmit the data generated each time, the network needs to dynamically schedule resources every time, which leads to problems such as high signaling overhead and long data transmission delay.

One is that the network can pre-configure periodic scheduling-free resources and transmit data through the scheduling-free resources without having to schedule resources every time the generated data is transmitted, thereby reducing signaling overhead and data transmission. delay, etc.

However, when periodic scheduling-free resources are used to transmit the currently generated data, the currently generated data may have non-periodic arrival, jitter, different data volume, etc., so the scheduling-free resources may be different from the currently generated data. The data is not suitable, affecting the reliability of data transmission and reducing resource utilization. For example, the current dispatch-free resource cannot be transmitted because the data has not arrived yet, or the current dispatch-free resource cannot be completely transmitted because the amount of data is too large, etc.

For another example, in this embodiment of the present application, the communication system may include multiple network devices and/or multiple terminal devices.

2. Data transmission process

1. User plane protocol stack for data transmission

The embodiments of this application mainly relate to the data transmission process. The following takes the data transmission process in the fifth generation (5G) new radio (new radio, NR) communication system as an example for illustrative explanation.

In the 5G NR communication system, data transmission can be through the service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and wireless link between network equipment and terminal equipment. User plane protocol stacks such as radio link control (RLC) layer, medium access control (MAC) layer, and physical (physical, PHY) layer are executed.

During the data transmission process, the SDAP layer maps IP data packets to different radio bearers (radio bearer, RB). Generally, data entities coming from or going to higher protocol layers are called service data units (SDUs), while data entities coming from or going to lower protocol layers are called protocol data units (PDUs). . Therefore, the SDAP layer outputs SDAP PDU to the PDCP layer by adding the SDAP header to the IP packet, and the PDCP layer outputs PDCP SDU to the SDAP layer. SDAP PDU is equivalent to PDCP SDU.

Similarly, the PDCP layer adds a PDCP header to the SDAP PDU to output the PDCP PDU to the RLC layer. The RLC layer outputs the RLC PDU to the MAC layer by adding an RLC header to the PDCP PDU.

Finally, the MAC layer will multiplex multiple RLC PDUs and add MAC headers to form a transport block (TB), and finally the PHY layer will perform channel coding, modulation, multi-antenna processing, and resource mapping on the TB to complete the process. transmission.

2. The difference between uplink and downlink data transmission

In actual data transmission, different transmission methods may be used for downlink data from network equipment to terminal equipment and uplink data from terminal equipment to network equipment.

For downlink data, the downlink resources required to transmit downlink data can be allocated by the network device (scheduling/configuration, etc.). Among them, the network device can determine the amount of downlink data to be transmitted to the terminal device each time and the time-frequency resource location of the downlink resources based on the amount of downlink data to be transmitted and the wireless channel condition of the terminal device. Afterwards, the MAC layer of the network device generates TB of corresponding size and then transmits it through the downlink resources.

For uplink data, the uplink resources required to transmit the uplink data can be allocated by the network device (scheduling/configuration, etc.). As shown in Figure 3, the uplink data transmission process is as follows:

First, the terminal device reports the amount of uplink data it stores to be transmitted to the network device;

Second, the network device allocates (scheduling/configuring, etc.) uplink resources to the terminal device based on the amount of uplink data to be transmitted;

Third, the MAC layer of the terminal device generates TBs of corresponding sizes based on the configured uplink resources, and then transmits them through the uplink resources.

3. Uplink data and downlink data

In this embodiment of the present application, the uplink data may be uplink data of a service, may be uplink data of the same (one) service, or may be uplink data of different (multiple) services.

In other words, the uplink data of a service can be the uplink data of the same service or the uplink data of multiple services. For example, Uplink data of Extended Reality (XR) business, XR business and online video business, etc.

It should be noted that XR business is mainly video business, and the data of this video business is in burst mode, that is, the data of XR business is generated periodically, usually there are 60 frames of video data in one second. That is, a video frame is generated every 16.6ms. Since the size of the data in one video frame may be too large, it will be split into dozens of IP packets. In other words, for a network that transmits XR services, dozens of IP data packets need to be transmitted every 16.6ms, and the arrival time of IP data packets is uncertain, with an approximate range of [-4, 4] ms, or [ -5,5]ms, and obeys the truncated Gaussian distribution.

Downlink data can be downlink data of a service, downlink data of the same (one) service, or downlink data of different (multiple) services.

In other words, the downlink data of a service can be the downlink data of the same service or the downlink data of multiple services.

In some possible implementations, the uplink data and downlink data may belong to the same service, or may belong to multiple different services, and there is no specific restriction on this.

In some possible implementations, services may include at least one of the following: delay-sensitive services, delay-sensitive and large-volume data services, low-latency and high-reliability services, low-latency and high-reliability services with large data volumes. Business or business with large data volume, etc.

For example, the service may include at least one of XR service, virtual reality (Virtual Reality, VR) service, online video service, online live broadcast service, online voice service, etc., and there is no specific limitation on this.

In some possible implementations, when the uplink data is uplink data of multiple services, there may be priorities between the uplink data of the multiple services. Therefore, the terminal device may need to transmit the uplink data of the multiple services sequentially according to priority.

For example, delay-sensitive and large-data-volume services have a higher priority, so the terminal device needs to first consider transmitting the delay-sensitive and large-data-volume services first.

4. Generation of uplink data

In this embodiment of the present application, the uplink data may be generated by an application in the application layer of the terminal device. Among them, the data generated by the same (certain) application can be uplink data of the same service, and the data generated by different (certain) applications can be uplink data of different services.

It should be noted that the data generated by the application in the application layer will be processed by the SDAP layer, PDCP layer and RLC layer to become RLC PDU, and then assembled into TB in the MAC layer, and finally transmitted through the PHY layer.

An application can be called an application (APP). An application program refers to a program that is designed to complete a certain/multiple specific tasks or have a certain function. The program runs on the operating system, can run on the application layer, interacts with the user, and has a visual user interface.

5. Generation of downlink data

In this embodiment of the present application, downlink data may be generated by an application server in the core network (or an application in the application layer of the application server). Among them, the data generated by the same (certain) application server can be the downlink data of the same service, and the data generated by different (certain) application servers can be the downlink data of different services.

In addition, the downlink data may be sent by the application server to the terminal device through the network device.

In this embodiment of the present application, the application server may be a software and hardware unit used to provide functions such as application data.

For example, the software and hardware unit may be infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SAAS) platform, etc.

6. Data distribution characteristics of business data

In this embodiment of the present application, the service data may be the uplink data of the service or the downlink data of the service. In addition, business data has certain data distribution characteristics. Among them, data distribution characteristics can be used to represent the distribution/distribution characteristics/distribution rules of data that describes the business through data statistics in at least one of cycle, data volume, generation time, arrival time, data packet location distribution, etc. wait.

In some possible implementations, the data distribution characteristics of business data may include at least one of the following: the data is generated periodically, the data volume range of the data, the arrival time of the data (arrival moment or arrival timing, etc.), the arrival of the data The jitter range of time (arrival moment or arrival timing, etc.), etc.

1) Data is generated periodically

In the embodiment of the present application, whether it is the data generated each time by the application in the application layer of the terminal device or the data generated each time by the application server, it may be periodic, that is, the data generated each time may be periodic. of.

For example, taking the uplink data generated each time by the XR service as an example, the XR application in the application layer of the terminal device can periodically generate a frame of video. Multiple data packets of the same frame of video can form a burst, that is, each burst contains multiple data packets. Arrives at the access layer and waits for transmission over the air interface. Among them, XR applications can periodically generate 60 frames of video per second, that is, there is a burst that needs to be transmitted every 16.67ms. Each burst contains multiple data packets, and the amount of data in each burst may fluctuate within a certain range. .

2) Data volume range of data

It should be noted that since the business may generate data periodically each time, and the data generated each time may be composed of multiple data packets, and different data packets may have different data sizes, so the data generated each time The amount of data may fluctuate within a certain range.

Based on this, the data volume range can be used to represent the range between the minimum data volume and the maximum data volume of data generated by the business each time.

For example, taking the above example as an example, since each burst contains multiple data packets, and different data packets have different data amounts, the data amount of the burst generated each time may be different, and the burst generated each time Has a range between the minimum and maximum data size.

3) Data arrival time

It should be noted that the arrival time of data can be understood as the time that the data generated by the service reaches the physical layer (or access layer) from the application layer to prepare for transmission.

The access layer can be understood as the protocol stack other than the application layer. For example, the user plane protocol stack includes the SDAP layer, PDCP layer, RLC layer, MAC layer, and PHY layer. The control plane protocol stack includes the NAS layer, RRC layer, and PDCP. layer, RLC layer, MAC layer and PHY layer.

In addition, in order to simplify the calculation, the embodiment of the present application can ignore the processing delay of data from the application layer to the access layer. Therefore, the time (time/timing) when the application in the application layer generates data, that is, the time when the data is generated by the application layer, can be equivalent to the time when the data reaches the physical layer (or access layer). In other words, from the perspective of the application layer, it is the time when the data is generated, and from the perspective of the access layer, it is the time when the data reaches the access layer.

In some possible implementations, the arrival time of data can be in absolute time units, or in superframe number/radio frame number (system frame number, SFN)/subframe number (subframe number)/slot number (slot index/number)/symbol (symbol index/number), etc.

It should be noted that in the frame structure of 5G NR, the duration of a wireless frame is fixed at 10ms, and each wireless frame contains 10 subframes, that is, the duration of each subframe is fixed at 1ms. Each subframe contains several (such as 1/2/4/816/32, etc.) time slots. For example, when the subcarrier spacing is 15KHz, each subframe contains 1 time slot, that is, each time slot is 1ms. Each slot contains 14 or 12 OFDM symbols. In addition, the transmission time interval (TTI) of 5G NR is 1 time slot.

For example, taking the above example as an example, the XR application can notify the access layer of the time when each burst periodically arrives at the access layer.

If the time is in absolute time units and the period is 17ms (for example, 60 frames are output per second, that is, a burst needs to be transmitted every 16.67ms (about 17ms)), then the current burst will be at 17:15 on December 20, 2021 It reaches the access layer in 32 seconds and 267ms, and the next burst will arrive at the access layer at 17:15:32 and 284ms on December 20, 2021.

If the time slot number is used and the period is 17 time slots (for example, 1 time slot is 1ms), the current burst will arrive at the access layer in time slot 20, and the next burst will arrive at the access layer in time slot 37. .

It should be noted that if superframe number/radio frame number/subframe number/slot number/symbol is used, the superframe number/radio frame number/subframe number/slot number/symbol can be mapped from the absolute time unit .

In addition, the superframe number/radio frame number/subframe number/slot number/symbol may not exist. For example, some cells do not use superframes, so there is no need to use superframe numbers; in some scenarios, only one of the subframe numbers or timeslot numbers is required.

4) Jitter range of data arrival time

It should be noted that the jitter range of data arrival time can be used to represent the range between the earliest time and the latest time when data arrives at the physical layer (or access layer).

7. Implementation method of data transmission

It should be noted that data needs to be transmitted through resources.

Combined with the content in "6. Data distribution characteristics of service data" above, network equipment can allocate (scheduling/configuring, etc.) resources according to the data distribution characteristics of service data, so that through the allocated (scheduled/configured, etc.) resources for data transmission.

In addition, in order to ensure data transmission, the network device can allocate (scheduling/configuration, etc.) resources to the terminal device before the time (time/timing) when the data reaches the physical layer (or access layer).

In this embodiment of the present application, the network device can allocate (schedule/configure, etc.) resources in the following ways:

8. Scheduling-free resources

1) Concept

It should be noted that scheduling-free resources can be understood as meaning that there is no need to schedule (allocate or configure, etc.) the resources for each generated data, that is, the resources only need to be configured once in advance and are valid periodically.

In this embodiment of the present application, the scheduling-free resources may include uplink scheduling-free resources and downlink scheduling-free resources. Among them, the uplink scheduling-free resources can be used to carry the uplink data of the service; the downlink scheduling-free resources can be used to carry the downlink data of the service.

In addition, uplink scheduling-free resources may include Configured Grant physical uplink shared channel (CG-PUSCH); downlink scheduling-free resources may include (Semi-Persistent Scheduling) physical downlink shared channel (SPS PDSCH).

For example, taking the uplink data of the service as an example, since the application in the application layer of the terminal device generates uplink data periodically, the uplink scheduling-free resources are periodic, and the uplink scheduling-free resources only need to be configured once, and the periodicity is effective , in order to help improve configuration efficiency.

As another example, taking the uplink data of the service as an example, the network device can directly pre-configure the terminal device according to the data distribution characteristics after receiving the data distribution characteristics of the service data and before the time when the first uplink data reaches the access layer. Periodic resources. Finally, after the first (or first) uplink data reaches the access layer, the terminal device can directly use the preconfigured periodic resources to transmit the first uplink data. Similarly, after the next (or next) uplink data reaches the access layer, the terminal device can directly use the pre-configured periodic resources to transmit the next uplink data, and so on.

2) Download the scheduling information of scheduling-free resources (allocation information/configuration information, etc.)

Since the data distribution characteristics of the data can include at least one of the following: the data is generated periodically, the data volume range of the data, the arrival time of the data (arrival moment or arrival timing, etc.), the arrival time of the data (arrival moment or arrival timing, etc.) ) jitter range, so the network device can determine the following scheduling information (allocation information/configuration information, etc.) of the scheduling-free resources based on the data distribution characteristics of the data:

●Period of scheduling-free resources

It should be noted that the network device can determine the period of the scheduling-free resource based on the data generation period/data arrival time/the jitter range of the data arrival time, etc.

●Time-domain resource size of scheduling-free resources

It should be noted that the network device can determine the time domain resource size of the scheduling-free resource according to the data volume, so that the scheduling-free resource can carry the data volume and prevent the data from being transmitted completely, thereby ensuring the reliability of data transmission.

In the embodiment of this application, the symbols may refer to Orthogonal Frequency Division Multiplexing (OFDM) symbols, or may refer to other types of symbols, and there is no specific limitation on this.

● Frequency domain resource size of scheduling-free resources

It should be noted that the network device can determine the size of the frequency domain resource of the scheduling-free resource according to the data volume, so that the scheduling-free resource can carry the data volume and prevent the data from being transmitted completely, thereby ensuring the reliability of data transmission.

In this embodiment of the present application, the frequency domain resource size of the scheduling-free resource may include the resource block (Resource Block, RB) position occupied by the scheduling-free resource, the number of occupied RBs, etc.

In the embodiment of this application, RB may refer to a physical resource block (Physical Resource Block, PRB) or a virtual resource block (VirtualResource Block, VRB). Among them, one RB can be 12 consecutive subcarriers in the frequency domain.

●The starting position of dispatch-free resources

It should be noted that the network device can determine the starting position of the scheduling-free resource based on the data generation cycle/data arrival time/the jitter range of the data arrival time, etc., so that the starting position of the current scheduling-free resource can be located at the current At a certain moment (such as a subframe/time slot, etc.) after the arrival time of the generated data, it is guaranteed that the scheduling-free resource can be used to transmit the data as soon as possible, thereby helping to reduce the waiting time for data transmission.

In addition, the starting position of the scheduling-free resource may be the starting time unit of the scheduling-free resource. The time unit can be understood as the communication granularity between the terminal device and the network device in the time domain, that is, the terminal device and the network device communicate in the time domain based on the time unit as the granularity/unit.

For example, the time unit may be a subframe, a time slot, a symbol, a mini-slot, etc., and is not limited to this.

Take the time unit as a time slot as an example. The starting position of the scheduling-free resource is the starting time slot of the scheduling-free resource. Similarly, taking the time unit as a symbol as an example, the starting position of the scheduling-free resource is the starting symbol of the scheduling-free resource.

●End position of dispatch-free resources

It should be noted that the network device can determine the end position of the scheduling-free resource according to the data generation cycle/data arrival time/the jitter range of the data arrival time, etc., so that the end position of the current scheduling-free resource can be located at the currently generated At a certain time after the arrival time of the data (such as subframe/time slot/frame, etc.), it is guaranteed that the scheduling-free resource can be used to transmit data, which is beneficial to ensuring the data Reliability of data transmission.

In addition, the end position of the scheduling-free resource may be the end time unit of the scheduling-free resource. The time unit can be understood as the communication granularity between the terminal device and the network device in the time domain, that is, the terminal device and the network device communicate in the time domain based on the time unit as the granularity/unit.

Take the time unit as a time slot as an example. The end position of the scheduling-free resource is the end time slot of the scheduling-free resource. Similarly, taking the time unit as the symbol as an example, the end position of the scheduling-free resource is the end symbol of the scheduling-free resource.

●Modulation and Coding Scheme (MCS)

3) Scheduling-free resource configuration (configuration)

In this embodiment of the present application, the scheduling-free resource configuration can be used to configure the scheduling-free resources.

During specific implementation, the scheduling-free resource configuration can be used to configure the scheduling information of the scheduling-free resources. For details of the scheduling information, please refer to the content in the above "2) Scheduling information of scheduling-free resources (allocation information/configuration information, etc.)". For example, period, time domain resource size, frequency domain resource size, starting position, ending position, MCS, etc.

It should be noted that the embodiments of the present application need to consider one or more scheduling-free resource configurations, and the scheduling information of the scheduling-free resources configured in different scheduling-free resource configurations is different.

For example, the period of the dispatch-free resource configured in a dispatch-free resource configuration is different from the period of the dispatch-free resource configured in a dispatch-free resource configuration.

For another example, the period of the scheduling-free resources configured in one scheduling-free resource configuration and another scheduling-free resource configuration is the same, but at least one of the time domain resource size, frequency domain resource size, starting position, end position, MCS, etc. The following items are different, and there are no specific restrictions on this.

In some possible implementations, if the embodiment of the present application only involves transmitting data of one service, then only one scheduling-free resource configuration can be used, and the same service can be transmitted through the scheduling-free resources configured in the scheduling-free resource configuration. The data. Of course, the embodiments of the present application can also configure multiple scheduling-free resources, and transmit data of the same service through the configured scheduling-free resources. There is no specific limitation on this.

In some possible implementations, if the embodiment of the present application requires the transmission of data involving multiple services, one or more scheduling-free resource configurations can be specifically used for each service, and the scheduling-free resource configurations used by different services are different.

Since different services use different scheduling-free resource configurations, it is possible to avoid using the same scheduling-free resources to carry data of different services and ensure the reliability of data transmission.

In some possible implementations, the dispatch-free resources configured in different dispatch-free resource configurations are used to carry data belonging to different services, thereby avoiding the same dispatch-free resources from carrying data of different services and ensuring the reliability of data transmission. .

In some possible implementations, scheduling-free resource configuration includes SPS PDSCH configuration (SPS PDSCH configuration) and CG-PUSCH configuration (CG-PUSCH configuration). Among them, SPS PDSCH configuration can be used to configure SPS PDSCH, and CG-PUSCH configuration can be used to configure CG-PUSCH.

In some possible implementations, the SPS PDSCH configuration can be represented by high-level information (such as information element SPS configuration (IE SPS-Config)).

In some possible implementations, CG-PUSCH configuration can be represented by high-level information (such as information element configuration grant configuration (IE ConfiguredGrantConfig)).

4)Problem

In the embodiment of this application, when periodic scheduling-free resources are used to transmit data generated by the service, since the data generated each time may have non-periodic arrival, arrival time jitter, different data volume, etc., this leads to Scheduling-free resources may not be suitable for the currently generated data, affecting the reliability of data transmission and reducing resource utilization.

For example, due to jitter, the arrival time of the currently generated data is far before or after the starting position of the current scheduling-free resource, making it impossible to use the current scheduling-free resource to transmit the currently generated data in a timely manner, thus reducing data transmission. reliability.

For another example, due to the increase in the amount of currently generated data, the current scheduling-free resources cannot completely transmit the currently generated data, thereby reducing the reliability of data transmission.

For another example, due to the reduction in data volume of the currently generated data, the current scheduling-free resources have a large amount of remaining resources when transmitting the currently generated data, thereby reducing resource utilization.

3. Ignore or receive dispatch-free resource configuration, ignore or receive dispatch-free resources

Since the scheduling-free resource configuration is used to configure the scheduling-free resources, and the scheduling-free resources may not be suitable for the generated data, and the scheduling-free resources are pre-configured and periodic, therefore the embodiment of the present application can be configured in a timely manner (or Real-time) instructs the terminal device/network device to ignore (or receive) one or some scheduling-free resource configurations (or scheduling-free resources).

It should be noted that when the network device instructs the terminal device to ignore the resource, it can be understood that the terminal device does not need to receive (or cancel reception, etc.) the resource, so that the terminal device can receive the resource without consuming power, which is beneficial to saving power consumption; In this way, the network device no longer needs to send the resource, which is helpful to avoid waste of resources, save resources, and improve resource utilization.

In addition, the network device instructs the terminal device to receive the resource, which can be understood as notifying the terminal device in advance that it needs to receive the resource, so that the terminal device can know in advance that the resource needs to be used for data transmission, so that the terminal device can adjust the data generation time and data in advance. Arrival time, etc., to ensure timely use of the resource to transmit data.

In this way, the network device can receive the resource without consuming power, which is beneficial to saving power consumption.

In addition, the terminal device instructs the network device to receive the resource, which can be understood as notifying the network device in advance that it needs to receive the resource, so that the network device can know in advance that the resource needs to be used for data transmission, so that the network device can adjust the data generation time and data in advance. Arrival time, etc., to ensure timely use of the resource to transmit data.

The relevant concepts and technical solutions involved in the embodiments of the present application will be described in detail below.

1. Instructions

In order to promptly (or real-time) instruct the terminal device/network device to ignore (or receive) a certain (or certain) scheduling-free resource configuration (or scheduling-free resource), the embodiment of the present application introduces indication information, so that the network device can pass The indication information indicates to the terminal device to ignore (or receive) a certain (or certain) scheduling-free resource configuration (or scheduling-free resources), or causes the terminal device to send the indication information to the network device to indicate ignoring (or receiving) a certain (or scheduling-free resource). or some) dispatch-free resource configuration (or dispatch-free resources).

In some possible implementations, the indication information can be used to instruct the terminal device to ignore or receive M (M is an integer greater than or equal to 1) scheduling-free resources under a scheduling-free resource configuration, and can be used to instruct the terminal device to ignore Or receive Q (Q is a positive integer) of P (P is an integer greater than or equal to Q) scheduling-free resource configurations, and there is no specific restriction on this.

Of course, the indication information can also be described using other terms, such as first information, first indication information, etc. As long as it has the same meaning/concept/function, etc., it is within the scope of inclusion required by this application, and there is no specific limitation on this. .

In some possible implementations, the indication information may be sent or received during cell search, cell reselection, uplink and downlink synchronization, cell access, cell camping, initial access, or uplink and downlink resource scheduling.

In some possible implementations, the indication information may be carried by system information (SI), high-level signaling (such as RRC signaling, DCI signaling), terminal device-specific signaling, etc.

In some possible implementations, the indication information may be carried by DCI in a physical downlink control channel (PDCCH), which is associated with scheduling-free resources.

In some possible implementations, the indication information may be carried by UCI in the Physical Uplink Shared Channel (PUSCH), which is associated with scheduling-free resources.

In the following specific embodiments, this application takes PDCCH as an example to illustrate the method of causing the terminal equipment to ignore a certain scheduling-free resource configuration through indication information. Those skilled in the art combine "making the terminal equipment ignore a certain scheduling-free resource configuration through indication information". The implementation of "Method" can be known as the implementation of "Method of causing network device to ignore certain scheduling-free resource configuration through indication information", which will not be described again. 2. PDCCH associated scheduling-free resources

In this embodiment of the present application, the PDCCH is associated with a scheduling-free resource, which may include a position where the monitoring position of the PDCCH is a preset offset before the starting position or end position of the scheduling-free resource. The preset offset is used to configure the PDCCH. high-level signaling carried.

It should be noted that the embodiment of the present application can configure the monitoring position of the PDCCH through high-level signaling, and the high-level signaling can configure the monitoring position of the PDCCH to be at a preset offset before the starting position or the ending position of the scheduling-free resource. The position and the preset offset are carried by the high-level signaling. Therefore, the terminal equipment can monitor the PDCCH at the PDCCH monitoring position for instructing to ignore (or receive) a certain (or certain) scheduling-free resource configuration (or scheduling-free resource), thereby establishing a connection between the PDCCH and the scheduling-free resource. connection relation.

For example, in Figure 2, the network device is configured with scheduling-free resources. The period of the scheduling-free resource is T, for example, the starting position A of the scheduling-free resource 210 to the starting position B of the scheduling-free resource 220 is T, and T=2ms. Then, the network device can configure the listening position of the PDCCH through higher layer signaling and configure the preset offset P-offset. Among them, the listening position of the first PDCCH is at the P-offset position C before the starting position A of the scheduling-free resource, and the listening position of the second PDCCH is at the P-offset position before the starting position B of the scheduling-free resource. D, and so on. In other words, the monitoring position of PDCCH is periodic. Finally, the terminal equipment monitors the PDCCH 230 at the listening position of the first PDCCH, and the DCI in the PDCCH 230 instructs the terminal equipment to ignore (or receive) the scheduling-free resource 220.

In addition, the PDCCH monitoring position may include the position of the PDCCH Monitoring Occasion.

3. Instruct one dispatch-free resource configuration to ignore or receive M dispatch-free resources.

It should be noted that this embodiment of the present application can use a scheduling-free resource configuration, and transmit data of the same service through the scheduling-free resources configured in the scheduling-free resource configuration.

The M scheduling-free resources may be M of the periodic scheduling-free resources configured in a scheduling-free resource configuration. Therefore, the M scheduling-free resources have the same period.

In addition, when the network device needs to instruct the terminal device to ignore or receive the M scheduling-free resources, the network device can send a PDCCH to the terminal device before the M scheduling-free resources, and the PDCCH will be associated with the Mth scheduling-free resources. One, and instructs the terminal equipment to ignore or receive the M scheduling-free resources through the DCI in the PDCCH.

For example, in Figure 2, the DCI in PDCCH 230 instructs the terminal device to ignore two scheduling-free resources, namely scheduling-free resources 210 and scheduling-free resources 220. Among them, PDCCH 230 is associated with scheduling-free resources 210.

In some possible implementations, the DCI in the PDCCH may be unicast DCI or group DCI.

In this embodiment of the present application, the DCI in the PDCCH instructs the terminal equipment to ignore or receive the M scheduling-free resources. The following methods may exist:

Way 1:

The DCI in the PDCCH may instruct the terminal equipment to ignore or receive the scheduling-free resources associated with the PDCCH, and/or to ignore or receive the M-1 scheduling-free resources after the scheduling-free resources associated with the PDCCH.

For example, in Figure 2, PDCCH 230 is associated with scheduling-free resources 210. Among them, the DCI indication in PDCCH 230 is as follows:

Instruct the terminal device to ignore the scheduling-free resource 210; or,

Instruct the terminal device to ignore the scheduling-free resource 210 and ignore the scheduling-free resource after the scheduling-free resource 210, that is, the scheduling-free resource 220; or,

The terminal device is instructed to ignore one scheduling-free resource after the scheduling-free resource 210, that is, the scheduling-free resource 220.

Way 2:

The DCI in the PDCCH may instruct the terminal equipment to ignore or receive M scheduling-free resources within a time period X after the location of the PDCCH.

That is to say, the M scheduling-free resources are within the time period X after the location of the PDCCH. Among them, the duration X is carried by the DCI in the PDCCH.

For example, in Figure 3, the DCI in PDCCH 330 instructs the terminal equipment to ignore the scheduling-free resources within the duration X after the location of the PDCCH, X=3ms. Since the scheduling-free resource 310 and the scheduling-free resource 320 are within the time period X, the terminal device needs to ignore the scheduling-free resource 310 and the scheduling-free resource 320 .

In some possible implementations, the location of the PDCCH may be the time unit where the PDCCH is located. The time unit can be understood as the communication granularity between the terminal device and the network device in the time domain, that is, the terminal device and the network device communicate in the time domain based on the time unit as the granularity/unit.

Taking the time unit as a time slot as an example, the location of the PDCCH is the time slot where the PDCCH is located. Similarly, taking the time unit as a symbol as an example, the position of the PDCCH is the symbol where the PDCCH is located.

In some possible implementations, the value of the duration X may be one of multiple first candidate values indicated by the DCI in the PDCCH in a bit index manner. Among them, the plurality of first candidate values may be specified by network configuration, preconfiguration, or protocol, and there is no specific limitation on this.

Of course, in order to facilitate distinction and description, the first candidate value can also be described using other terms, and there is no specific limitation on this.

It should be noted that when K (K is an integer greater than or equal to 1) first candidate values are configured, the DCI in the PDCCH is indicated from the K first candidate values through log2(K) bit indexing. one.

For example, taking K as 4 as an example, in Table 1, when the DCI indication bit index in the PDCCH is "00", the value of duration X is the first first candidate value.

Table 1

In some possible implementations, the DCI in the PDCCH can jointly indicate ignore (or receive) and the value of duration X through bit indexing.

It should be noted that when K (K is an integer greater than or equal to 1) first candidate values are configured, the DCI in the PDCCH jointly indicates ignore (or receive) and follow from the log2(K) bit index method. Indicates one of the K first candidate values.

For example, taking K as 4 as an example, in Table 2, when the DCI indication bit index in the PDCCH is "01", the terminal equipment needs to receive scheduling-free resources within the duration X, and the value of the duration The two first candidate values.

Table 2

Way 3:

The DCI in the PDCCH may instruct the terminal equipment to ignore or receive the scheduling-free resources within M scheduling-free resource periods after the location of the PDCCH.

That is to say, the M scheduling-free resources are within M scheduling-free resource periods after the location of the PDCCH. Among them, the number M of scheduling-free resource periods is carried by the DCI in the PDCCH.

In some possible implementations, the location of the PDCCH may be the time unit where the PDCCH is located. For details, please refer to the above similar descriptions, which will not be described again.

It should be noted that since there is one scheduling-free resource period within one scheduling-free resource period, there are M scheduling-free resource periods within M scheduling-free resource periods.

For example, in Figure 2, the DCI in PDCCH 230 instructs the terminal equipment to ignore the scheduling-free resources within 1 scheduling-free resource period after the location of the PDCCH. The terminal device needs to ignore the scheduling-free resource 210.

In some possible implementations, the value of the number of scheduling-free resource periods M may be one of multiple second candidate values indicated by the DCI in the PDCCH in a bit index manner. The plurality of second candidate values may be specified by network configuration, pre-configuration, or protocol, and there is no specific limitation on this.

Of course, in order to facilitate distinction and description, the second candidate value can also be described using other terms, and there is no specific limitation on this.

It should be noted that when S (S is an integer greater than or equal to 1) second candidate values are configured, the DCI in the PDCCH is indicated from the S second candidate values through log2(S) bit indexing. one.

For example, taking S as 4 as an example, in Table 3, when the DCI indication bit index in the PDCCH is "00", the value of the number of scheduling-free resource periods M is the first second candidate value.

table 3

In some possible implementations, the DCI in the PDCCH can jointly indicate ignoring (or receiving) and the value of the number M of scheduling-free resource periods through bit indexing.

It should be noted that when S (S is an integer greater than or equal to 1) second candidate values are configured, the DCI in the PDCCH jointly indicates ignoring (or receiving) and following through the log2(S) bit index method. Indicates one of the S second candidate values.

For example, taking S as 4 as an example, in Table 4, when the DCI indication bit index in the PDCCH is "01", the terminal equipment needs to receive scheduling-free resources within M scheduling-free resource periods, and the scheduling-free resources The value of period M is the second second candidate value.

Table 4

4. Instruct to ignore or accept Q of P scheduling-free resource configurations

It should be noted that this embodiment of the present application can use P scheduling-free resource configurations, and transmit data of multiple services (such as XR services and other services) through the scheduling-free resources configured in the P scheduling-free resource configurations. Among them, the dispatch-free resources configured in different dispatch-free resource configurations are used to carry data belonging to different services.

In addition, when the network device needs to instruct the terminal device to ignore or receive Q of the P scheduling-free resource configurations, the network device can The PDCCH is sent to the terminal equipment before the Q scheduling-free resource configurations, and the terminal equipment is instructed to ignore or receive the Q scheduling-free resource configurations within the PDCCH period through the DCI in the PDCCH.

For example, in Figure 4, the period between PDCCH 410 and PDCCH 440 is t. Among them, the DCI in the PDCCH 410 instructs the terminal equipment to ignore two scheduling-free resource configurations within the period t, namely the scheduling-free resource configuration 420 and the scheduling-free resource configuration 430.

In some possible implementations, the PDCCH period of the PDCCH may be configured by higher layer signaling.

In this embodiment of the present application, the DCI in the PDCCH instructs the terminal equipment to ignore or receive the Q scheduling-free resource configurations within the PDCCH cycle. The following methods may exist:

Method A:

The DCI in the PDCCH instructs the terminal equipment to ignore or receive the Q scheduling-free resource configurations from the P scheduling-free resource configurations in the PDCCH period in a bitmap manner.

That is to say, Q scheduling-free resource configurations are indicated by DCI through bitmaps from P scheduling-free resource configurations.

It should be noted that the size of the bitmap is P bits, and each scheduling-free resource configuration corresponds to a bitmap bit in the bitmap, so that each scheduling-free resource configuration is addressable.

For example, if the bitmap bit corresponding to a certain scheduling-free resource configuration is 1, it means that the terminal device needs to ignore the scheduling-free resource configuration; otherwise, it means that the terminal device accepts the scheduling-free resource configuration. Or, if the bitmap bit corresponding to a certain scheduling-free resource configuration is 1, it means that the terminal device needs to receive the scheduling-free resource configuration; otherwise, it means that the terminal device ignores the scheduling-free resource configuration.

Method B:

The DCI in the PDCCH can instruct the terminal equipment to ignore or receive the Q scheduling-free resource configurations from the P scheduling-free resource configurations in the PDCCH period in a bit index manner.

That is to say, Q scheduling-free resource configurations are indicated by DCI from P scheduling-free resource configurations through bit indexing.

It should be noted that the DCI in the PDCCH jointly indicates ignoring (or receiving) and indicating Q from P scheduling-free resource configurations in a bit index manner.

For example, taking P as 4 as an example, in Table 5, when the DCI indication bit index in the PDCCH is "010", the terminal equipment needs to ignore the first scheduling-free resource configuration, the second scheduling-free resource configuration and the third scheduling-free resource configuration. Scheduling resource configuration requires receiving the fourth scheduling-free configuration.

table 5

For example, taking P as 4 as an example, in Table 6, when the DCI in the PDCCH indicates that the bit index corresponding to the first scheduling-free resource configuration is “1”, the terminal device needs to ignore the first scheduling-free resource configuration. According to the same method, the DCI in the PDCCH indicates the index corresponding to each of the remaining three scheduling-free resource configurations.

Table 6

5. Indicate the length of time each of the Q scheduling-free resource configurations needs to be ignored or received.

It should be noted that, on the basis of the content in "4. Instructing to ignore or receive Q of P scheduling-free resource configurations" above, the DCI in the PDCCH can also indicate that each of the Q scheduling-free resource configurations requires The length of time to ignore or receive.

The specific implementation is that the DCI in the PDCCH jointly indicates ignoring (or receiving), indicating Q from P scheduling-free resource configurations, and the duration of ignoring (or receiving) through bit indexing.

For example, taking P as 4 as an example, in Table 7, when the DCI indication bit index in the PDCCH is "010", the terminal equipment needs to To ignore the first dispatch-free resource configuration, the second dispatch-free resource configuration and the third dispatch-free resource configuration, you need to receive the fourth dispatch-free resource configuration. The first dispatch-free resource configuration is ignored for 1ms, and the second dispatch-free resource configuration is ignored. The duration is 2ms, and the ignoring duration of the third scheduling-free resource configuration is 2ms.

Table 7

For example, taking P as 4 as an example, in Table 8, when the DCI in the PDCCH indicates that the bit index corresponding to the first scheduling-free resource configuration is "1", the terminal device needs to ignore the first scheduling-free resource configuration, And the ignoring duration of the first scheduling-free resource configuration is 1ms. According to the same method, the DCI in the PDCCH indicates the index corresponding to each of the remaining three scheduling-free resource configurations.
