Description

Communication method and device, terminal equipment, network equipment and chip

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus, a terminal device, a network device, and a chip.

Background

The standard protocol defined by the third generation partnership project organization (3rd Generation Partnership Project,3GPP) defines the transmission of data, such as upstream or downstream data. Among them, in data transmission, there may be the following implementation manner:

one is that the network may dynamically schedule resources and transmit data over the dynamically scheduled resources. However, in order to realize the transmission of the data generated each time, the network needs to dynamically schedule the resources each time, so that the signaling overhead is high, and the time delay of the data transmission is high.

One is that the network may pre-configure periodic non-scheduled resources and perform data transmission through the non-scheduled resources without needing to schedule the resources each time the generated data is transmitted, thereby reducing signaling overhead, delay of data transmission, and the like.

However, when the current generated data is transmitted by using the periodic scheduling-free resource, the current generated data may have aperiodic arrival, jitter, different data volume, and the like, so that the scheduling-free resource may not be adapted to the current generated data, the reliability of data transmission is affected, and the resource utilization rate is reduced. For example, data on the current no-dispatch resource has not arrived yet and cannot be transmitted, data on the current no-dispatch resource is too large to be transmitted, etc.

Disclosure of Invention

The application provides a communication method and device, a terminal device, a network device and a chip, which aim to timely (or real-time) instruct the terminal device to ignore or receive M non-scheduled resources under one non-scheduled resource configuration through indication information, so that the terminal device can receive the ignored non-scheduled resources without consuming power consumption, thereby being beneficial to saving power consumption, and the network device can send the ignored non-scheduled resources without any more, being beneficial to avoiding resource waste, saving resources and improving resource utilization rate.

In a first aspect, the present application is a communication method applied to a terminal device; the method comprises the following steps:

receiving indication information, wherein the indication information is used for indicating the terminal equipment to ignore or receive M non-scheduling resources under one non-scheduling resource configuration, the non-scheduling resource configuration is used for configuring the non-scheduling resources, and M is an integer greater than or equal to 1;

the scheduling-free resource comprises a semi-persistent scheduling physical downlink shared channel SPS PDSCH or a configuration grant physical uplink shared channel CG-PUSCH, wherein the SPS PDSCH is used for bearing downlink data of a service, and the CG-PUSCH is used for bearing uplink data of the service.

As can be seen, since the non-scheduling resource configuration is used to configure non-scheduling resources, the non-scheduling resources may not be adapted to uplink data (or downlink data) of the service, and the non-scheduling resources are preconfigured and periodic, the embodiment of the present application may instruct the terminal device in time (or in real time) to ignore or receive M non-scheduling resources under one non-scheduling resource configuration. Therefore, the terminal equipment can receive the ignored scheduling-free resources without consuming power consumption, which is beneficial to saving the power consumption; the network device can avoid sending the ignored scheduling-free resources, thereby being beneficial to avoiding the waste of the resources, saving the resources and improving the utilization rate of the resources.

the scheduling-free resource is SPS PDSCH or CG-PUSCH, the SPS PDSCH is used for bearing downlink data of a service, and the CG-PUSCH is used for bearing uplink data of the service.

Therefore, the terminal equipment can receive the non-scheduling resources configured by the omitted non-scheduling resource configuration without consuming power consumption, thereby being beneficial to saving the power consumption; the network device can avoid the need of sending the omitted scheduling-free resources configured by the scheduling-free resource configuration, thereby being beneficial to avoiding the waste of resources, saving the resources and improving the utilization rate of the resources.

Therefore, the embodiment of the application needs to adjust the scheduling information of the scheduling-free resource, and indicates the adjustment of the scheduling information of the scheduling-free resource in time (or in real time), so that the adjusted scheduling information of the scheduling-free resource is matched with the uplink data or the downlink data of the service, and the transmission reliability of the data of the service is ensured.

3. Network equipment

In the embodiment of the present application, the network device may be a device with a transceiver function, which is used for communication with the terminal device. For example, the network device may be responsible for radio resource management (radio resource management, RRM), quality of service (quality of service, qoS) management, data compression and encryption, data transceiving, etc. on the air side. The network device may be a Base Station (BS) in a communication system or a device deployed in a radio access network (radio access network, RAN) for providing wireless communication functions.

The DUs are responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (radio link control, RLC), medium access control (medium access control, MAC) and Physical (PHY) layers. In addition, the AAU can realize partial physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, in this network deployment, higher layer signaling (e.g., RRC signaling) may be considered to be transmitted by the DU or transmitted by both the DU and the AAU. It is understood that the network device may include at least one of CU, DU, AAU. In addition, the CU may be divided into network devices in the RAN, or may be divided into network devices in the core network, which is not particularly limited.

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

2. Data transmission process

1. User plane protocol stack for data transmission

Embodiments of the present application relate generally to data transmission procedures, and are described below by way of example with respect to data transmission procedures in a fifth generation (5G) New Radio (NR) communication system.

In the 5G NR communication system, data transmission may be performed through a user plane protocol stack of a service data adaptation protocol (service data adaptation protocol, SDAP) layer, a packet data convergence protocol (packet data convergence protocol, PDCP) layer, a radio link control (radio link control, RLC) layer, a medium access control (medium access control, MAC) layer, a Physical (PHY) layer, and the like between a network device and a terminal device.

During data transfer, the SDAP layer maps IP packets to different Radio Bearers (RBs). In general, data entities from or to a higher protocol layer are called service data units (service data unit, SDUs) and data entities from or to a lower protocol layer are called protocol data units (protocol data unit, PDUs). Thus, the SDAP layer outputs SDAP PDUs to the PDCP layer by adding SDAP headers to the IP packets, and the PDCP layer outputs PDCP SDUs to the SDAP layer, which are equivalent to the PDCP SDUs.

Similarly, the PDCP layer outputs PDCP PDUs to the RLC layer by adding PDCP headers to the SDAP PDUs. The RLC layer outputs RLC PDUs to the MAC layer by adding RLC headers to the PDCP PDUs.

Finally, the MAC layer multiplexes multiple RLC PDUs and adds a MAC header to form a Transport Block (TB), and finally the PHY layer performs processes such as channel coding, modulation, multi-antenna processing, and resource mapping on the TB for transmission.

2. Distinction between uplink and downlink data transmission

In actual data transmission, different transmission modes may be adopted for downlink data from the network device to the terminal device and uplink data from the terminal device to the network device.

For downstream data, downstream resources required for transmitting downstream data may be allocated (scheduled/configured, etc.) by the network device. The network device may determine, according to the data amount of the downlink data to be transmitted and the wireless channel condition of the terminal device, the data amount of the downlink data and the time-frequency resource location of the downlink resource transmitted to the terminal device each time. And then, the MAC layer of the network equipment generates a TB with a corresponding size, and then transmits the TB through downlink resources.

For uplink data, uplink resources required for transmitting the uplink data may be allocated (scheduled/configured, etc.) by the network device. As shown in fig. 3, the transmission flow of the uplink data is as follows:

Firstly, a terminal device reports the data quantity of uplink data to be transmitted stored by the terminal device to a network device;

secondly, the network equipment allocates (schedules/configures and the like) uplink resources for the terminal equipment according to the data quantity of the uplink data to be transmitted;

thirdly, the MAC layer of the terminal equipment generates a TB with a corresponding size according to the configured uplink resource, and then transmits the TB through the uplink resource.

3. Uplink data and downlink data

In the embodiment of the application, the uplink data can be uplink data of a service, can be uplink data of the same (one) service, and can also be uplink data of different (multiple) services.

That is, the uplink data of the service may be uplink data of the same service or uplink data of a plurality of services. For example, uplink data of Extended Reality (XR) service, uplink data of XR service and online video service, and the like.

It should be noted that XR service is mainly video service, and data of the video service is in burst mode, that is, data of the XR service is periodically generated, and typically, 60 frames of video data are provided in 1 second. That is, one video frame is generated every 16.6 ms. Since the size of the data amount in one video frame may be too large, it may be fragmented into several tens of IP packets. That is, for a network to transmit XR traffic, tens of IP packets need to be transmitted every 16.6ms, and the arrival time of the IP packets has uncertainty, roughly ranging within [ -4,4] ms, or [ -5,5] ms, and obeying a truncated gaussian distribution.

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

That is, the downlink data of the service may be downlink data of the same service or downlink data of a plurality of services.

In some possible implementations, the uplink data and the downlink data may belong to the same service data, or may belong to multiple different service data, which is not particularly limited.

In some possible implementations, the traffic may include at least one of: delay sensitive traffic, delay sensitive and data volume large traffic, low delay high reliability and data volume large traffic or data volume large traffic, etc.

For example, the service may include at least one of an XR service, a Virtual Reality (VR) service, an online video service, an online live service, an online voice service, and the like, which is not particularly limited.

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

For example, a service that is delay sensitive and has a large data volume has a higher priority, so the terminal device needs to consider that the service that is delay sensitive and has a large data volume is preferentially transmitted.

4. Generation of upstream data

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

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

An application may be referred to as an application program (APP). An application is a program that runs on an operating system to perform a specific task or tasks or to have a function, and can run on an application layer to interact with a user, with a visual user interface.

5. Generation of downstream data

In an embodiment of the present application, the downlink data may be generated by an application server in the core network (or an application in an application layer of the application server). The data generated by the same (some) application server may be downlink data of the same service, and the data generated by different (some) application servers may be 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 the embodiment of the application, the application server can be a software and hardware unit for providing functions such as application data.

For example, the software and hardware units may be infrastructure as a service (infrastructure as a service, iaaS), platform as a service (platform as a service, paaS), software as a service (software as service, SAAS) platform, and the like.

For another example, the application server may be a cloud server, a hardware server, a software and hardware server, a web server, a load balancer (nminx), a data center network device, a personal computer (personal computer, PC), a computing device, a computer supporting 802.11 protocol, or the like, which is not particularly limited.

6. Data distribution features for data of a service

In the embodiment of the application, the service data can be uplink service data or downlink service data. In addition, the data of the service has certain data distribution characteristics. Wherein the data distribution feature may be used to represent a distribution situation/distribution feature/distribution rule or the like of data describing the service by data statistics on at least one of a period, a data amount, a generation time, an arrival time, a packet location distribution or the like.

In some possible implementations, the data distribution characteristics of the data of the service may include at least one of: the data is a periodically generated data amount range of data, arrival time of data (arrival time or arrival time sequence, etc.), jitter range of arrival time of data (arrival time or arrival time sequence, etc.), and the like.

1) The data being generated periodically

In the embodiment of the present application, whether 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 may have periodicity, that is, the data generated each time may be periodic.

For example, taking uplink data generated by XR service each time as an example, an XR application in an application layer of the terminal device may periodically generate a frame of video. Multiple packets of the same frame of video may form a burst (burst), i.e., each burst contains multiple packets, which collectively arrive at the access layer awaiting transmission over the air. The XR application may periodically generate 60 frames of video every second, that is, every 16.67ms has a burst to be transmitted, where each burst includes multiple data packets, and the data amount of each burst may fluctuate within a certain range.

2) Data volume range of data

It should be noted that, since the service may periodically generate data each time, and each time the generated data may be composed of a plurality of data packets, and different data packets may have different data size, the data size of each time the generated data may fluctuate within a certain range.

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

For example, in the above example, since each burst contains a plurality of data packets, and different data packets have different amounts of data, there may be different amounts of data per burst generated, and each burst generated has a range between the minimum amount of data and the maximum amount of data.

3) Arrival time of data

The arrival time of data is understood to be the time when data generated by a service arrives at a physical layer (or an access layer) from an application layer to prepare for transmission.

The access layer may be understood as a protocol stack other than the application layer, such as a user plane protocol stack including an SDAP layer, a PDCP layer, an RLC layer, a MAC layer, and a PHY layer, and a control plane protocol stack including a NAS layer, an RRC layer, a PDCP layer, an RLC layer, a MAC layer, and a PHY layer.

In addition, in order to simplify the calculation, the embodiment of the application can ignore the processing time delay of the data from the application layer to the access layer. Thus, the time (time/timing) at which an application in the application layer generates data, i.e., the time at which the data is generated by the application layer, may be equivalent to the time at which the data arrives at the physical layer (or access layer). Or, from the application layer, the time of data generation, and from the access layer, the time of data arrival at the access layer.

In some possible implementations, the arrival time of the data may be in absolute time units, or may be super frame number (hyperframe 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 one radio frame is fixed to 10ms, and each radio frame includes 10 subframes, that is, the duration of each subframe is fixed to 1ms. Each subframe contains several (e.g., 1/2/4/816/32, etc.) slots, e.g., 1 slot when the subcarrier spacing is 15KHz, i.e., 1ms per slot. Each slot contains 14 or 12 OFDM symbols. In addition, the transmission time interval (transmission time interval, TTI) of 5G NR is 1 slot.

For example, using the above example, the XR application may inform the access stratum of the time each burst periodically arrives at the access stratum.

If the time takes absolute time units and the period is 17ms (e.g. 60 frames are output per second, i.e. there is one burst to be transmitted every 16.67ms (about 17 ms)), then the current burst arrives at the access layer at 267ms of 15 minutes 32 seconds at 2021, 12, 20, 17, and the next burst arrives at the access layer at 284ms of 15 minutes 32 seconds at 2021, 12, 20, 17.

If the time takes a slot number and the period is 17 slots (e.g., 1 slot is 1 ms), then the current burst arrives at the access stratum at slot 20 and the next burst will arrive at the access stratum at slot 37.

If the super frame number/radio frame number/subframe number/slot number/symbol is used, the super frame number/radio frame number/subframe number/slot number/symbol may be mapped by an 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 a superframe and do not need to use a superframe number; in some cases, only one of the subframe number or the slot number needs to be indicated.

4) Jitter range of arrival time of data

The jitter range of the arrival time of data may be used to represent a range between the earliest time and the latest time when the data arrives at the physical layer (or access layer).

7. Implementation of data transmission

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

In combination with the content in the above "6, data distribution characteristics of data of a service", the network device may allocate (schedule/configure, etc.) resources according to the data distribution characteristics of the data of the service so as to perform data transmission by the allocated (scheduled/configured, etc.) resources.

In addition, in order to ensure transmission of data, the network device may allocate (schedule/configure, etc.) resources to the terminal device before the time (time/timing) when the data arrives at the physical layer (or access layer).

In an embodiment of the present application, the network device may allocate (schedule/configure etc.) resources by:

8. Scheduling-free resources

1) Concept of

It should be noted that, the scheduling-free resource is understood to be that the scheduling (allocation or configuration, etc.) is not required for the resource of the data generated each time, that is, the resource is only required to be configured in advance once, and the periodicity is effective.

In the embodiment of the application, the scheduling-free resources can comprise uplink scheduling-free resources and downlink scheduling-free resources. Wherein, the uplink scheduling-free resource can be used for bearing uplink data of the service; the downlink scheduling-free resource can be used for carrying downlink data of the service.

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

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

For another example, taking uplink data of the service as an example, the network device may pre-configure periodic resources for the terminal device directly according to the data distribution feature after receiving the data distribution feature of the service data and before the time when the first uplink data arrives at the access layer. Finally, after the first (or first) uplink data arrives at the access layer, the terminal device may directly use the preconfigured periodic resources to transmit the first uplink data. Similarly, after the next (or next) uplink data arrives at the access layer, the terminal device may directly use the preconfigured periodic resources to transmit the next uplink data, and so on.

2) Scheduling information (allocation information/configuration information, etc.) of lower non-scheduling resource

The data distribution characteristics of the data may include at least one of: the data is periodically generated, and the data volume range of the data, the arrival time (reaching time or reaching time sequence and the like) of the data, and the jitter range of the arrival time (reaching time or reaching time sequence and the like) of the data, so that the network equipment can determine the following scheduling information (allocation information/configuration information and the like) of the scheduling-free resources according to the data distribution characteristics of the data:

cycles of scheduling-free resources

The network device may determine the period of the scheduling-free resource according to the generation period of the data, the jitter range of the arrival time of the data, and the like.

Time domain resource size of scheduling-free resources

It should be noted that, the network device may determine the time domain resource size of the scheduling-free resource according to the data amount of the data, so that the scheduling-free resource can bear the data amount of the data, and avoid that the data cannot be transmitted completely, thereby being beneficial to ensuring the reliability of data transmission.

In the embodiment of the application, the time domain resource size of the scheduling-free resource can comprise the time unit position occupied by the scheduling-free resource in a time slot/subframe/frame, the number of occupied time units and the like.

In the embodiment of the present application, the symbol may refer to an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, or may refer to other types of symbols, which is not particularly limited.

Frequency domain resource size of scheduling-free resources

It should be noted that, the network device may determine the frequency domain resource size of the scheduling-free resource according to the data amount of the data, so that the scheduling-free resource can bear the data amount of the data, and avoid that the data cannot be transmitted completely, thereby being beneficial to ensuring the reliability of data transmission.

In the embodiment of the present application, the frequency domain Resource size of the scheduling-free Resource may include a Resource Block (RB) position occupied by the scheduling-free Resource, the number of RBs occupied, and the like.

In an embodiment of the present application, an RB may refer to a physical resource block (Physcial Resource Block, PRB) or a virtual resource block (VirtualResource Block, VRB). Wherein one RB may be 12 consecutive subcarriers in the frequency domain.

Starting position of scheduling-free resource

It should be noted that, the network device may determine the starting position of the scheduling-free resource according to the generation period of the data, the jitter range of the arrival time of the data, and the like, so that the current starting position of the scheduling-free resource may be located at a time (such as a subframe/a time slot, etc.) after the arrival time of the currently generated data, so as to ensure that the scheduling-free resource can transmit the data as soon as possible, thereby being beneficial to reducing the waiting time of data transmission.

In addition, the starting position of the scheduling-free resource may be a starting time unit of the scheduling-free resource. In this case, a time unit is understood to mean the granularity of the communication between the terminal device and the network device in the time domain, i.e. the terminal device and the network device communicate in the time domain with the granularity of the time unit.

For example, the time unit may be a subframe, a slot, a symbol, a mini-slot, etc., which is not limited thereto.

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

End position of scheduling-free resource

It should be noted that, the network device may determine the end position of the scheduling-free resource according to the generation period of the data, the jitter range of the arrival time of the data, and the like, so that the end position of the current scheduling-free resource may be located at a time (such as a subframe, a slot, a frame, and the like) after the arrival time of the currently generated data, so as to ensure that the scheduling-free resource can be utilized to transmit the data, thereby being beneficial to ensuring the reliability of data transmission.

The end position of the scheduling-free resource may be an end time unit of the scheduling-free resource. In this case, a time unit is understood to mean the granularity of the communication between the terminal device and the network device in the time domain, i.e. the terminal device and the network device communicate in the time domain with the granularity of the time unit.

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

Modulation and coding strategy (Modulation and Coding Scheme, MCS)

3) Scheduling-free resource allocation (configuration)

In the embodiment of the application, the scheduling-free resource allocation can be used for allocating the scheduling-free resource.

In particular implementations, the no-scheduling resource configuration may be used to configure scheduling information for no-scheduling resources. The scheduling information can be described in detail in the above "2) scheduling information (allocation information/configuration information, etc.) of the scheduling-free resource. Such as period, time domain resource size, frequency domain resource size, start position, end position, MCS, etc.

It should be noted that, in the embodiment of the present application, one or more non-scheduling resource configurations need to be considered, and scheduling information of non-scheduling resources configured by different non-scheduling resource configurations is different.

For example, the period of one non-scheduled resource configured by one non-scheduled resource configuration is different from the period of one non-scheduled resource configured by one non-scheduled resource configuration.

For another example, the period of the non-scheduled resource configured by one non-scheduled resource configuration is the same as that of the non-scheduled resource configured by another non-scheduled resource configuration, but at least one of the time domain resource size, the frequency domain resource size, the start position, the end position, the MCS, and the like is different, which is not particularly limited.

In some possible implementations, if the embodiment of the present application only involves transmitting data of one service, only one scheduling-free resource configuration may be used, and the data of the same service may be transmitted through the scheduling-free resource configured by the scheduling-free resource configuration. Of course, the embodiment of the present application may also use a plurality of non-scheduling resource configurations, and transmit the data of the same service through the non-scheduling resources configured by the plurality of non-scheduling resource configurations, which is not particularly limited.

In some possible implementations, if the embodiment of the present application needs to transmit data related to multiple services, one or more scheduling-free resource configurations may be used exclusively for each service, and the scheduling-free resource configurations used by different services are different.

Because different services use different scheduling-free resource configurations, the same scheduling-free resource can be prevented from bearing data of different services, and the reliability of data transmission is ensured.

In some possible implementations, the different scheduling-free resources are configured to allocate the scheduling-free resources, and the data used for bearing belong to different services, so that the same scheduling-free resources can be prevented from bearing the data of different services, and the reliability of data transmission is ensured.

In some possible implementations, the scheduling-free resource configurations include SPS PDSCH configurations (SPS PDSCH configuration) and CG-PUSCH configurations (CG-PUSCH configurations). Wherein, SPS PDSCH configuration may be used to configure SPS PDSCH and CG-PUSCH configuration may be used to configure CG-PUSCH.

In some possible implementations, the SPS PDSCH configuration may be represented by higher layer information, such as a cell SPS configuration (IESPS-Config).

In some possible implementations, the CG-PUSCH configuration may be represented with higher layer information, such as an information element configuration grant configuration (IE ConfiguredGrantConfig).

4) Problem(s)

In the embodiment of the application, when the data generated by the service is transmitted by using the periodic scheduling-free resource, the scheduling-free resource is possibly not matched with the currently generated data because the generated data may have aperiodic arrival, arrival time jitter, different data quantity and the like, thereby influencing the reliability of data transmission and reducing the utilization rate of the resource.

For example, the arrival time of the currently generated data is far before or after the starting position of the current scheduling-free resource due to jitter, so that the currently generated data cannot be transmitted by using the current scheduling-free resource in time, thereby reducing the reliability of data transmission.

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

For another example, since the current generated data has a reduced data amount, the current scheduling-free resource has a large amount of remaining resources when the current generated data is transmitted, thereby reducing the resource utilization.

3. Ignoring or receiving a scheduling-free resource configuration, ignoring or receiving a scheduling-free resource

Since the non-scheduled resource configuration is used for configuring non-scheduled resources, the non-scheduled resources may not be matched with the generated data, and the non-scheduled resources are pre-configured and periodic, the embodiment of the application can instruct the terminal device to ignore (or receive) some or some non-scheduled resource configurations (or non-scheduled resources) in time (or in real time).

It should be noted that, the network device instructs the terminal device to ignore the resource, and it can be understood that the terminal device does not need to receive (or cancel receiving, etc.) the resource, so that the terminal device can receive the resource without consuming power consumption, which is beneficial to saving power consumption; therefore, the network equipment can not need to send the resource again, which is beneficial to avoiding the waste of the resource, saving the resource and improving the utilization rate of the resource.

In addition, the network device indicates the terminal device to receive the resource, which can be understood as informing the terminal device in advance that the resource needs to be received, so that the terminal device can know in advance that the resource needs to be utilized for data transmission, so that the terminal device can adjust the generation time of the data, the arrival time of the data and the like in advance, and the data can be transmitted by utilizing the resource in time.

The related concepts and technical schemes related to the embodiments of the present application are specifically described below.

1. Indication information

In order to timely (or real-time) instruct the terminal device to ignore (or receive) a certain (or some) non-scheduling resource configuration (or non-scheduling resource), the embodiment of the application introduces the instruction information, so that the network device can instruct the terminal device to ignore (or receive) a certain (or some) non-scheduling resource configuration (or non-scheduling resource) through the instruction information.

In some possible implementations, the indication information may be used to instruct the terminal device to ignore or receive M (M is an integer greater than or equal to 1) non-scheduled resources in one non-scheduled resource configuration, and may be used to instruct the terminal device to ignore or receive Q (Q is a positive integer) in P (P is an integer greater than or equal to Q) non-scheduled resource configurations, where no specific limitation is imposed on this.

Of course, the indication information may also be described by other terms such as the first information, the first indication information, etc., which are not particularly limited as long as they have the same meaning/concept/function, etc., within the scope of the present application as claimed.

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

In some possible implementations, the indication information may be carried by System Information (SI), higher layer signaling (e.g., RRC signaling, DCI signaling), terminal device specific signaling, and the like.

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

2. PDCCH associated scheduling-free resources

In the embodiment of the application, the PDCCH is associated with the scheduling-free resource, and may include a position of a preset offset before a start position or an end position of the scheduling-free resource in a monitoring position of the PDCCH, where the preset offset is carried by a higher layer signaling for configuring the PDCCH.

It should be noted that, in the embodiment of the present application, the listening position of the PDCCH may be configured by a higher layer signaling, and the higher layer signaling may configure the listening position of the PDCCH to be at a position of a preset offset before the starting position or the ending position of the scheduling-free resource, where the preset offset is carried by the higher layer signaling. Therefore, the terminal device may monitor the PDCCH for indicating to ignore (or receive) a certain (or some) scheduling-free resource configuration (or scheduling-free resource) at the monitoring position of the PDCCH, thereby establishing an association relationship between the PDCCH and the scheduling-free resource.

For example, in fig. 2, the network device is configured with non-scheduled resources. The period of the non-scheduling resource is T, for example, the starting position a of the non-scheduling resource 210 to the starting position B of the non-scheduling resource 220 are T, and t=2ms. Then, the network device may configure the listening position of the PDCCH through higher layer signaling and configure a preset offset P-offset. The first PDCCH is monitored at a P-offset position C before a starting position a of the scheduling-free resource, and the second PDCCH is monitored at a P-offset position D before a starting position B of the scheduling-free resource, and so on. That is, the listening position of the PDCCH is periodic. Finally, the terminal device listens to PDCCH 230 at the listening position of the first PDCCH, and DCI in PDCCH 230 instructs the terminal device to ignore (or receive) non-scheduled resource 220.

In addition, the listening position of the PDCCH may include the position of a PDCCH listening occasion (PDCCH Monitoring Occasion).

3. Indicating M non-scheduling resources to be ignored or received under one non-scheduling resource configuration

It should be noted that, in the embodiment of the present application, a scheduling-free resource configuration may be used, and data of the same service may be transmitted through a scheduling-free resource configured by the scheduling-free resource configuration.

The M non-scheduling resources may be M periodic non-scheduling resources configured in one non-scheduling resource configuration. Thus, the M non-scheduled resources have the same periodicity.

In addition, when the network device needs to instruct the terminal device to ignore or receive the M non-scheduled resources, the network device may send a PDCCH to the terminal device before the M non-scheduled resources, where the PDCCH may be associated with a first one of the M non-scheduled resources, and instruct the terminal device to ignore or receive the M non-scheduled resources through DCI in the PDCCH.

For example, in fig. 2, DCI in PDCCH 230 instructs the terminal device to ignore 2 non-scheduled resources, namely non-scheduled resource 210 and non-scheduled resource 220. Wherein PDCCH 230 is associated with scheduling-free resource 210.

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

In the embodiment of the present application, the DCI in the PDCCH indicates the terminal device to ignore or receive the M scheduling-free resources, and may exist in the following manner:

mode 1:

the DCI in the PDCCH may instruct the terminal device to ignore or receive the non-scheduled resource associated with the PDCCH and/or to ignore or receive M-1 non-scheduled resources after the non-scheduled resource associated with the PDCCH.

For example, in fig. 2, PDCCH 230 is associated with scheduling-free resource 210. Wherein, DCI in PDCCH 230 is indicated as follows:

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

instructing the terminal device to ignore the non-scheduled resource 210 and ignore 1 non-scheduled resource after the non-scheduled resource 210, i.e. the non-scheduled resource 220; or,

the terminal device is instructed to ignore 1 non-scheduled resource after non-scheduled resource 210, i.e. non-scheduled resource 220.

Mode 2:

the DCI in the PDCCH may instruct the terminal device to ignore or receive M scheduling-free resources within a time period X after the PDCCH is located.

That is, the M non-scheduled resources are within a time period X after the PDCCH is located. Wherein, the duration X is carried by DCI in the PDCCH.

For example, in fig. 3, DCI in PDCCH 330 instructs the terminal device to ignore the scheduling-free resources within a time period X after the PDCCH is located, x=3 ms. Since the no-dispatch resource 310 and no-dispatch resource 320 are within the time length X, the terminal device needs to ignore the no-dispatch resource 310 and no-dispatch resource 320.

In some possible implementations, the location of the PDCCH may be the time unit in which the PDCCH is located. In this case, a time unit is understood to mean the granularity of the communication between the terminal device and the network device in the time domain, i.e. the terminal device and the network device communicate in the time domain with the granularity of the time unit.

Taking a time unit as a time slot as an example, the position of the PDCCH is the time slot of the PDCCH. Similarly, taking a time unit 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 indicated by the DCI in the PDCCH from a plurality of first candidate values by means of a bit index. The plurality of first candidate values may be defined by a network configuration, a pre-configuration, and a protocol, which is not particularly limited.

Of course, for convenience of distinguishing the description, the first candidate value may also be described by other terms, which are not particularly limited.

When K (K is an integer greater than or equal to 1) first candidate values are configured, DCI in the PDCCH indicates one of the K first candidate values by a log2 (K) bit index method.

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 the duration X is the first candidate value.

TABLE 1

Bit Index (Index)	Value of duration X
		00	First candidate value
01	Second first candidate value
		10	Third first candidate value
11	Fourth first candidate value

In some possible implementations, DCI in the PDCCH may jointly indicate the value of time length X to ignore (or receive) by means of a bit index.

When K (K is an integer greater than or equal to 1) first candidate values are configured, DCI in the PDCCH indicates neglect (or reception) jointly by a log2 (K) bit index method and 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 device needs to receive the scheduling-free resource within the duration X, and the value of the duration X is the second first candidate value.

TABLE 2

Bit index	Ignoring or receiving	Value of duration X
			00	Neglecting	First candidate value
01	Reception of	Second first candidate value
			10	Reception of	Third first candidate value
11	Neglecting	Fourth first candidate value

Mode 3:

the DCI in the PDCCH may instruct the terminal device to ignore or receive the non-scheduled resources within M non-scheduled resource periods after the PDCCH is located.

That is, the M non-scheduled resources are within M non-scheduled resource periods after the PDCCH is located. Wherein, the number M of the scheduling-free resource periods is carried by DCI in the PDCCH.

In some possible implementations, the location of the PDCCH may be the time unit in which the PDCCH is located. The details of the method are similar to those described above, and will not be repeated.

It should be noted that, since there are 1 non-scheduling resource periods within 1 non-scheduling resource period, there are M non-scheduling resource periods within M non-scheduling resource periods.

For example, in fig. 2, DCI in PDCCH 230 instructs the terminal device to ignore non-scheduled resources within 1 non-scheduled resource period after the PDCCH is located. The terminal device needs to ignore the non-scheduled resources 210.

In some possible implementations, the value of the number M of scheduling-free resource periods may be one indicated by DCI in the PDCCH from a plurality of second candidate values by means of a bit index. The plurality of second candidate values may be defined by a network configuration, a pre-configuration, and a protocol, which is not particularly limited.

Of course, for convenience of distinguishing the description, the second candidate value may also be described by other terms, which are not particularly limited.

When S (S is an integer greater than or equal to 1) second candidate values are configured, DCI in the PDCCH indicates one of the S second candidate values by a log2 (S) bit index method.

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 M of non-scheduling resource periods is the first and second candidate values.

TABLE 3 Table 3

Bit index	Value of number M of scheduling-free resource periods
		00	First and second candidate values
01	Second candidate value
		10	Third second candidate value
11	Fourth second candidate value

In some possible implementations, DCI in the PDCCH may jointly indicate the value of the number M of the ignore (or receive) and non-scheduled resource periods by means of a bit index.

When S (S is an integer greater than or equal to 1) second candidate values are configured, DCI in the PDCCH indicates neglect (or reception) jointly by a log2 (S) bit index method and 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 device needs to receive the scheduling-free resource within M scheduling-free resource periods, and the value of the scheduling-free resource period M is the second candidate value.

TABLE 4 Table 4

Bit index	Ignoring or receiving	Value of duration X
			00	Neglecting	First candidate value
01	Reception of	Second first candidate value
			10	Reception of	Third first candidate value
11	Neglecting	Fourth and fourthOne-time selection value

4. Indicating to ignore or receive Q of the P schedule-free resource configurations

It should be noted that, in the embodiment of the present application, P non-scheduling resource configurations may be used, and data of multiple services (such as XR service and other services) may be transmitted through non-scheduling resources configured by the P non-scheduling resource configurations. Wherein, different scheduling-free resources are configured to allocate the configured scheduling-free resources, and the data used for bearing belong to different services.

In addition, when the network device needs to instruct the terminal device to ignore or receive Q of the P non-scheduled resource configurations, the network device may send a PDCCH to the terminal device before the Q non-scheduled resource configurations, and instruct the terminal device to ignore or receive the Q non-scheduled resource configurations in the PDCCH period through DCI in the PDCCH.

For example, in fig. 4, the period between PDCCH 410 and PDCCH 420 is t. Wherein, the DCI in PDCCH 410 instructs the terminal device to ignore 2 non-scheduled resource configurations in period t, namely non-scheduled resource configuration 420 and non-scheduled resource configuration 430.

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

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

In the embodiment of the present application, the DCI in the PDCCH indicates that the terminal device ignores or receives the Q scheduling-free resource configurations in the PDCCH period, and may be in the following manner:

mode a:

the DCI in the PDCCH indicates the terminal equipment to ignore or receive the Q non-scheduling resource configurations in the PDCCH period from the P non-scheduling resource configurations in a bitmap mode.

That is, Q non-scheduled resource configurations are indicated by DCI from P non-scheduled resource configurations in a bitmap manner.

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

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

Mode B:

the DCI in the PDCCH may instruct the terminal device to ignore or receive the Q non-scheduled resource configurations in the PDCCH period from the P non-scheduled resource configurations in a bit index manner.

That is, Q non-scheduled resource configurations are indicated by DCI from P non-scheduled resource configurations by way of a bit index.

The DCI in the PDCCH indicates to ignore (or receive) and Q out of P scheduling-free resource configurations jointly by means of bit index.

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 device needs to ignore the first non-scheduled resource configuration, the second non-scheduled resource configuration, and the third non-scheduled resource configuration, and needs to receive the fourth non-scheduled 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 indexes corresponding to the other 3 scheduling-free resource configurations.

TABLE 6

Bit index	First scheduling-free resource allocation
		0	Reception of
1	Neglecting

5. Indicating the duration of time that each of the Q scheduling-free resource configurations needs to ignore or receive

In addition, on the basis of the content in "4, indicating to ignore or receive Q of the P non-scheduled resource configurations", DCI in the PDCCH may also indicate the duration of time for which each of the Q non-scheduled resource configurations needs to ignore or receive.

The specific implementation is that the DCI in the PDCCH jointly indicates to ignore (or receive) in a bit index mode, and indicates Q time periods and duration of ignore (or receive) from P scheduling-free resource configurations.

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 device needs to ignore the first non-scheduled resource configuration, the second non-scheduled resource configuration, and the third non-scheduled resource configuration, and needs to receive the fourth non-scheduled configuration, where the first non-scheduled resource configuration ignores for 1ms, the second non-scheduled resource configuration ignores for 2ms, and the third non-scheduled resource configuration ignores for 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 duration of the first scheduling-free resource configuration is 1ms. According to the same method, the DCI in the PDCCH indicates indexes corresponding to the other 3 scheduling-free resource configurations.

TABLE 8

Bit index	First scheduling-free resource allocation	Duration of neglect
			0	Reception of	-
1	Neglecting	1ms

4. Adjustment of scheduling information indicating scheduling-free resources

Because the non-scheduling resource is configured to be used for configuring the non-scheduling resource, the non-scheduling resource may not be matched with the generated data, and the non-scheduling resource is preconfigured and periodic, the embodiment of the application needs to adjust the scheduling information of the non-scheduling resource, and indicates the adjustment of the scheduling information of the non-scheduling resource in time (or in real time). Wherein the non-scheduled resources may be configured by one or more non-scheduled resource configurations.

It should be noted that, the scheduling information of the scheduling-free resource may be detailed in the above "scheduling information (allocation information/configuration information, etc.) of the scheduling-free resource under the above" 2) ", which will not be described in detail.

For example, the starting position or the ending position after adjustment of the scheduling-free resource is indicated.

1. Indication information

In order to realize timely (or real-time) indication of adjustment of scheduling information of the scheduling-free resources, the embodiment of the application introduces indication information, so that the network equipment can indicate the scheduling information of the scheduling-free resources after adjustment to the terminal equipment through the indication information.

In some possible implementations, the indication information may be used to indicate adjustment of scheduling information of the scheduling-free resources configured by the one or more scheduling-free resource configurations; or, the method can be used for indicating the scheduling information after the adjustment of the scheduling-free resources configured by the one or more scheduling-free resource configurations; or, indicating adjustment of scheduling information of a scheduling-free resource configured by one or more scheduling-free resource configurations; or, the scheduling information after the adjustment of the non-scheduling resources is indicated, and the non-scheduling resources are configured by one or more non-scheduling resource configurations, which are not particularly limited.

The "indication information" in the "fourth" adjustment of the scheduling information indicating the scheduling-free resource "is different from the" third "adjustment of the scheduling-free resource, the" indication information "in the" neglecting or receiving the scheduling-free resource configuration "and the" neglecting or receiving the scheduling-free resource ", but is the information introduced by the scheduling-free resource, and has relevance.

In some possible implementations, the indication information may be carried by DCI in the PDCCH.

2. Adjusting starting or ending position of scheduling-free resources

It should be noted that, in the embodiment of the present application, the starting position or the ending position after adjustment of the scheduling-free resource may be indicated by DCI in the PDCCH.

In some possible implementations, the adjusted starting or ending location of the scheduling-free resource may exist in the following manner:

mode 1:

the starting position or the ending position after the adjustment of the scheduling-free resource is positioned at the position of a first time unit interval after the position of the PDCCH, and the first time unit interval is carried by DCI in the PDCCH.

It should be noted that, the location of the PDCCH may be a time unit where the PDCCH is located, which is specifically described in the similar description, and will not be repeated.

The first time unit interval may be an interval or an offset with granularity of time unit. The time units may be specifically described in the similar manner, and will not be described again.

For example, taking a time unit as a time slot, the first time unit interval is an interval or offset in time slots. Similarly, taking a time unit as a symbol as an example, the first time unit interval is an interval or offset by a symbol.

Of course, the first time unit interval may be described in other terms, which are not particularly limited.

In some possible implementations, the first time unit interval may be one indicated by DCI in the PDCCH from among a plurality of first candidate time unit intervals by way of a bit index. The plurality of first candidate time unit intervals may be defined by a network configuration, a pre-configuration, and a protocol, which is not particularly limited.

Of course, for convenience of distinguishing description, the first candidate time unit interval may also be described in other terms, which is not particularly limited.

When H (H is an integer greater than or equal to 1) first candidate time unit intervals are arranged, DCI in the PDCCH indicates one of the H first candidate time unit intervals by a log2 (H) bit index method.

For example, taking H as 4 as an example, in table 9, when the DCI indication bit index in the PDCCH is "00", the first time unit interval is the first candidate time unit interval.

TABLE 9

Bit index	First time unit interval
		00	First candidate time unit interval
01	Second first candidate time unit interval
		10	Third first candidate time unit interval
11	Fourth first candidate time unit interval

Mode 2:

the starting position or the ending position after the adjustment of the scheduling-free resource is positioned at a second time unit interval position after the absolute time unit, and the second time unit interval is carried by DCI in the PDCCH.

The absolute time unit may be an absolute position with granularity of time unit, and the absolute position is specified by network configuration, pre-configuration or protocol. The time units may be specifically described in the similar manner, and will not be described again.

The second time unit interval may be an interval or an offset having a granularity of a time unit.

For example, taking a time unit as a time slot, the second time unit interval is an interval or offset in time slots. Similarly, taking a time unit as an example of a symbol, the second time unit interval is a symbol interval or offset.

Of course, the second time unit interval may be described in other terms, which are not particularly limited.

In some possible implementations, the second time unit interval may be one indicated by DCI in the PDCCH from among a plurality of second candidate time unit intervals by way of a bit index. The plurality of second candidate time unit intervals may be defined by a network configuration, a pre-configuration, and a protocol, which is not particularly limited.

Of course, for convenience of distinguishing the description, the second candidate time unit interval may also be described in other terms, which is not particularly limited.

When H (H is an integer greater than or equal to 1) second candidate time unit intervals are arranged, DCI in the PDCCH indicates one from the H second candidate time unit intervals by a log2 (H) bit index method.

For example, taking H as 4 as an example, in table 10, when the DCI indication bit index in the PDCCH is "00", the second time unit interval is the first second candidate time unit interval.

Table 10

Bit index	Second time unit interval
		00	First and second candidate time unit intervals
01	Second candidate time unit interval
		10	Third second candidate time unit interval
11	Fourth second candidate time unit interval

3. Adjusting time domain resource size of scheduling-free resources

It should be noted that, in the embodiment of the present application, the DCI in the PDCCH may indicate the time domain resource size after adjustment of the scheduling-free resource.

In some possible implementations, the time domain resource size after adjustment of the scheduling-free resource may include: and adjusting the time unit position and/or the number of the time units occupied by the scheduling-free resources.

The time unit position can be a time domain position with the granularity of the time unit; the number of time units may be the number of particles in time units.

For example, taking a time unit as a time slot as an example, the time unit position is the time slot position; the number of time units is the number of time slots.

For another example, taking a time unit as a symbol, the time unit position is the symbol position; the number of time units is the number of symbols.

In some possible implementations, the time domain resource size after adjustment of the scheduling-free resource is one indicated by DCI in the PDCCH from a plurality of candidate time domain resource sizes by way of a bit index. The plurality of candidate time domain resource sizes may be defined by network configuration, pre-configuration and protocol, and are not particularly limited.

Of course, for convenience of distinguishing descriptions, the candidate time domain resource size may also be described in other terms, which are not particularly limited.

When W (W is an integer greater than or equal to 1) candidate time domain resource sizes are configured, DCI in the PDCCH indicates one from the W candidate time domain resource sizes by a log2 (W) bit index method.

4. Adjusting the frequency domain resource size of a scheduling-free resource

It should be noted that, in the embodiment of the present application, the MCS after adjustment of the scheduling-free resource may be indicated by DCI in the PDCCH.

In some possible implementations, the MCS adjusted without scheduling resources may be one indicated by DCI in the PDCCH from among a plurality of candidate MCSs by way of a bit index. The plurality of candidate MCSs may be defined by a network configuration, a pre-configuration, or a protocol, and are not particularly limited.

Of course, for ease of distinguishing descriptions, the candidate MCS may also be described in other terms, which are not particularly limited.

When Z (Z is an integer greater than or equal to 1) candidate MCSs are arranged, DCI in the PDCCH indicates one from the Z candidate MCSs by a log2 (Z) bit index method.

6. Jointly indicating the scheduling information after the adjustment of the scheduling-free resources configured under one or more scheduling-free resource configurations in a bit index mode

In the above description, DCI in the PDCCH may independently indicate the adjusted scheduling information (such as the adjusted starting position and ending position) of one or more non-scheduling resources configured under the non-scheduling resource configuration by a bit index manner, but the embodiment of the present application also indicates the adjusted scheduling information jointly by a bit index manner.

When the DCI indication bit index in the PDCCH is "10", the scheduling information adjusted for the scheduling-free resource configured in the scheduling-free resource configuration is mode 2. In mode 2, the initial position after adjustment of the non-scheduling resource is at a position of a third first candidate time unit interval after the position of the PDCCH, the time domain resource size after adjustment of the non-scheduling resource is the third candidate time domain resource size, the frequency domain resource size after adjustment of the non-scheduling resource is the third candidate frequency domain resource size, and the adjusted MCS is the third candidate MCS.

For example, in combination with table 11, the adjusted scheduling information of the scheduling-free resources configured under the 4 scheduling-free resource configurations is indicated jointly by means of bit indexes, as shown in table 12. When the DCI indication bit index in the PDCCH is 10, the scheduling information after the adjustment of the scheduling-free resources configured under the first scheduling-free resource configuration is mode 2;

6. Exemplary illustrations of a communication method

In combination with the foregoing "three, ignoring or receiving the scheduling-free resource configuration, ignoring or receiving the scheduling-free resource" and other related contents, the following embodiments of the present application take interaction between a terminal device and a network device as an example, and an exemplary description is given of a communication method of the embodiments of the present application. The terminal device may be a chip, a chip module, a module, or the like for the execution subject of the method. That is, the method is applied to the terminal device. Correspondingly, for the execution subject of the method, the network device may also be a chip, a chip module or a module, etc. That is, the method is applied in a network device.

Fig. 5 is a schematic flow chart of a communication method according to an embodiment of the present application, which specifically includes the following steps:

s510, the network device sends indication information, the indication information is used for indicating the terminal device to ignore or receive M non-scheduling resources under the configuration of a non-scheduling resource, the non-scheduling resource is configured to be used for configuring the non-scheduling resource, and M is an integer greater than or equal to 1.

The scheduling-free resource comprises SPS PDSCH or CG-PUSCH, the SPS PDSCH is used for carrying downlink data of the service, and the CG-PUSCH is used for carrying uplink data of the service.

It should be noted that, the "indication information", "no-scheduling resource configuration", "no-scheduling resource", "service", etc. refer to the content or other related content in the "three, neglect or receive no-scheduling resource configuration, neglect or receive no-scheduling resource" described above in detail, which will not be described herein.

It should be noted that, the PDCCH associated non-scheduling resource may be described in detail in the above "2, PDCCH associated non-scheduling resource".

It can be seen that, in the embodiment of the present application, the indication information may be carried by DCI in the PDCCH, so as to implement transmission or reception of the indication information. In addition, by establishing the association relation between the PDCCH and the scheduling-free resources, DCI in the PDCCH can instruct the terminal equipment to ignore or receive M scheduling-free resources associated with the PDCCH under one scheduling-free resource configuration.

In some possible implementations, PDCCH associates scheduling-free resources, including:

the monitoring position of the PDCCH is at a position of a preset offset before the starting position or the ending position of the scheduling-free resource, and the preset offset is carried by a high-layer signaling for configuring the PDCCH.

It can be seen that, in the embodiment of the present application, the listening position of the PDCCH may be configured by a higher layer signaling, and the higher layer signaling may configure the listening position of the PDCCH to be at a position of a preset offset before the starting position or the ending position of the scheduling-free resource, where the preset offset is carried by the higher layer signaling. Therefore, the terminal device can monitor the PDCCH used for indicating to ignore or receive the M non-scheduling resources at the monitoring position of the PDCCH, thereby establishing the association relationship between the PDCCH and the non-scheduling resources.

In some possible implementations, the M non-scheduled resources are within a time duration X after the PDCCH is located, the time duration X being carried by the DCI.

In some possible implementations, the value of the duration X is one indicated by the DCI from among a plurality of first candidate values by way of a bit index.

It should be noted that, in combination with the above "3, indicating that M scheduling-free resources are ignored or received under one scheduling-free resource configuration", DCI in the PDCCH in the embodiment of the present application may indicate one of a plurality of first candidate values as a value of a duration X in a bit index manner, which is easy to implement.

In some possible implementations, the number M of non-scheduled resource periods is carried by the DCI within M non-scheduled resource periods after the PDCCH is located.

It should be noted that, in combination with the content of "3" indicating that M non-scheduling resources are ignored or received under one non-scheduling resource configuration ", the embodiment of the present application carries the number M of non-scheduling resource periods through DCI in PDCCH, so that M non-scheduling resources needing to be ignored or received are within M non-scheduling resource periods after the PDCCH, and thus, it is easy to determine which one or more of the periodic non-scheduling resources need to be ignored or received through the M non-scheduling resource periods.

In some possible implementations, the value of the number M of scheduling-free resource periods is indicated by the DCI from one of the plurality of second candidate values by way of a bit index.

It should be noted that, in combination with the above "3, indicating that M non-scheduling resources are ignored or received under one non-scheduling resource configuration", DCI in the PDCCH in the embodiment of the present application may indicate one non-scheduling resource period number M from the second candidate value in a bit index manner, which is easy to implement.
