Description

Communication method and device

Technical field

This application relates to the field of mobile communication technology, and in particular to a communication method and device.

Background technique

The current 5G NR supports uplink transmission with two types of configuration authorization (uplink transmission with configured grant). The authorization of these two types of configuration is the authorization of the first type of configuration (Type 1 configured grant, or configured grant Type 1) and the second type of authorization. Configured authorization (Type 2 configured grant, or configured grant Type 2). In order to support a variety of services with different requirements for delay and reliability, NR also supports the configuration of more than one set (for example, up to 12 sets) of authorization on the same bandwidth part. In this case, the base station An index or identification (ID) will be established for each set of configured authorization, and the index or identification information will be carried in the configured authorization configuration information and sent to the terminal.

Regarding the configuration of the configured authorization for the terminal, NR also supports the release of the configured authorization. When multiple sets of authorizations for the second configuration are configured for the terminal, NR supports the release of authorizations for the second configuration one by one (that is, one set of authorizations for the second configuration is released each time), and it also supports the simultaneous release of multiple sets of second configurations. The authorization of class configuration is to support joint release. When releasing multiple sets of authorizations of the second type configuration, the network side device configures a release state set through RRC signaling. The state set contains one or more states, and each state is associated with one or more sets of the second type. Configured authorization. Which set or sets of authorizations for the second type of configuration are specifically released is indicated by the downlink control information (DCI) issued by the network side device. The DCI includes a field for indicating the status. In the release scenario, This domain is also called a release domain, and which set or sets of authorizations for the second type of configuration are released is determined by the value indicated by the release domain. In addition, in the release scenario, the DCI also needs to meet the release verification (validation) condition, and the authorization associated with the second type of configuration in this state will be released. Release verification (validation) conditions include: for example, the redundancy version (RV) field in DCI is set to all 0s, the modulation and coding scheme (MCS) field is set to all 1s, and the frequency domain resource allocation (frequency domain) The resource assignment (FDRA) field satisfies a preset condition. For example, when the authorized resource allocation type of the released second type of configuration is type 0, the FDRA field is set to all 0s. The above-mentioned use of the FDRA domain to satisfy the preset condition to verify whether the received DCI is a solution for releasing the DCI can reduce the probability of misjudging a certain DCI as the released DCI, and improve the reliability of the verification.

The premise of using the FDRA domain to improve the validation performance of the released DCI is that the value set in the FDRA domain in the released DCI is an invalid value, that is, the value will not be used to activate the authorization of the second type of configuration, otherwise the terminal may not be able to follow The FDRA domain judges whether the received DCI is used for activation or release.

However, in the case of joint release, a state is associated with multiple sets of authorizations for the second configuration, and the resource allocation types of the authorizations for the multiple second configurations may also be different. Use the FDRA domain to verify the validity of the DCI release At this time, misjudgment may occur, for example, the original DCI for other purposes is misjudged as the DCI for release, or the DCI for activation is misjudged as the DCI for release.

The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device communication (device-to-device, D2D) terminal equipment, vehicle-to-everything (V2X) Terminal equipment, machine-to-machine/machine-type communications (M2M/MTC) terminal equipment, Internet of things (IoT) terminal equipment, subscriber unit, subscriber station (subscriber station), mobile station (mobile station), remote station (remote station), access point (access point, AP), remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal) , User agent (user agent), or user equipment (user device), etc. For example, it may include mobile phones (or "cellular" phones), computers with mobile terminal equipment, portable, pocket-sized, hand-held, mobile devices with built-in computers, and so on. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants, PDA), and other equipment. It also includes restricted devices, such as devices with low power consumption, or devices with limited storage capabilities, or devices with limited computing capabilities. Examples include barcodes, radio frequency identification (RFID), sensors, global positioning system (GPS), laser scanners and other information sensing equipment.

As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices can also be called wearable smart devices or smart wearable devices, etc. It is a general term for using wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes Wait. A wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories. Wearable devices are not only a kind of hardware device, but also realize powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include full-featured, large-sized, complete or partial functions that can be implemented without relying on smart phones, such as smart watches or smart glasses, and only focus on a certain type of application function, and need to cooperate with other devices such as smart phones. Use, such as all kinds of smart bracelets, smart helmets, smart jewelry, etc. for physical sign monitoring.

The various terminal devices described above, if they are located on the vehicle (for example, placed in the vehicle or installed in the vehicle), can be regarded as vehicle-mounted terminal equipment, for example, the vehicle-mounted terminal equipment is also called on-board unit (OBU). ).

2) Network equipment, including, for example, access network (AN) equipment, such as a base station (e.g., access point), which may refer to equipment that communicates with wireless terminal equipment through one or more cells on the air interface in the access network Or, for example, a network device in a V2X technology is a roadside unit (RSU).

For example, in the LTE system or the NR system, when the terminal device has data transmission requirements, it usually sends a scheduling request (SR) to the network side device through the physical uplink control channel (physical uplink control channel, PUCCH) or through the physical uplink shared channel (physical uplink shared channel, PUSCH) reports a non-empty buffer state (BS) to the network side device, and the network side device receives the SR or non-empty buffer state report (buffer state report, BSR) sent by the terminal device , Send downlink control information (DCI) to the terminal device through the physical downlink control channel (PDCCH), and the DCI carries the uplink (UL) grant, and the UL grant is used to authorize the terminal The device uses specified configuration parameters, such as modulation and coding scheme (MCS), to send data on specified resources. The BSR is usually sent through media access control (MAC) layer signaling, and the BSR is carried in the MAC control element (CE) in the packet header of the data packet. In this article, the process of sending data from a terminal device to a network-side device is referred to as data transmission based on dynamic type authorization (grant based, GB) or dynamic type scheduling. Through dynamic type scheduling, the real-time channel information between the terminal device and the network side device can be used more efficiently, so that the location and size of the appropriate time-frequency resource, as well as the appropriate transmission parameters, can be specified for each transmission of the terminal device, which can be effective Improve the reliability of data transmission.

In the above-mentioned data transmission process based on dynamic type authorization, the terminal device needs to send SR or BSR to the network side device before sending data, and then the network side device will authorize through DCI, so this process will introduce delay and PDCCH signaling Overhead. At the same time, because the reception of PDCCH usually requires terminal equipment to aggregate different control channel element (CCE) aggregation levels (AL), different DCI formats (formats), and different DCI lengths on different time-frequency resources. Different radio network temporary identifiers (RNTI) perform blind detection, which requires a lot of power consumption. In order to reduce time delay, signaling overhead, and power consumption of terminal equipment, LTE and NR have introduced semi-persistent scheduling (SPS) transmission technology and grant-free (GF) transmission technology. SPS transmission technology and GF transmission technology are both network side equipment through high-level signaling and/or physical layer signaling in a semi-static manner to configure time-frequency resources and transmission parameters for terminal equipment to be used for data transmission. . When the terminal device has data transmission requirements, it directly uses the semi-statically configured time-frequency resources and transmission parameters to send data to the network-side device without sending SR or BSR to the network-side device (therefore, Figure 1 is shown with a dashed line). Need to wait for the process of uplink authorization, so as to achieve the purpose of reducing transmission delay, signaling overhead and terminal power consumption.

4) Uplink authorization-free transmission. NR supports two types of uplink authorization-free transmission. These two types of uplink authorization-free transmission are respectively the first type of configured grant (Type 1 configured grant, or configured grant Type 1) and the second type of configured grant (Type 2 configured grant, or configured grant Type 2).

In the first type of allocation authorization, the network side device sends configured authorization configuration (configured grant configuration) information to the terminal device through radio resource control (radio resource control, RRC) signaling, and the configuration information is used to configure, for example, time domain resources Cycle, open-loop power control related parameters, waveform, redundancy version sequence, number of repetitions, frequency hopping mode, resource allocation type, hybrid automatic retransmission request (HARQ) process number, demodulation reference signal (demodulation) Reference signal, DMRS) related parameters, modulation and coding scheme (MCS) tables, resource block group (RBG) size, and all transmission resources and transmissions of time domain resources, frequency domain resources, MCS, etc. parameter. After receiving the configuration information, the terminal device can immediately use the configured transmission parameters to perform PUSCH transmission on the configured time-frequency resources.

The difference between the authorization of the second type of configuration and the authorization of the first type of configuration is that the authorization of the second type of configuration is divided into two steps. First, the network side device sends the configured authorization configuration information through RRC signaling. Used to configure the period of time domain resources, open-loop power control related parameters, waveforms, redundancy version sequence, number of repetitions, frequency hopping mode, resource allocation type, HARQ process number, DMRS related parameters, MCS table, RBG size, etc. The transmission resources and transmission parameters within the network; then the network side device activates the PUSCH transmission based on the second type of configuration authorization through DCI, and the network side device configures other transmission resources including time domain resources, frequency domain resources, DMRS, MCS, etc. And transmission parameters. It should be noted that the DCI is a DCI scrambled using a first radio network temporary identity (RNTI), for example, a configured scheduling radio network temporary identity (CS-RNTI) is used. Scrambling DCI. Of course, the first RNTI may also be other possible RNTIs. In the following, the first RNTI is a CS-RNTI as an example. After determining the authorization configuration information, the terminal device cannot immediately use the resources and parameters configured by the configuration information for PUSCH transmission. Instead, it can perform PUSCH transmission after receiving the corresponding DCI for activation and configuring other resources and parameters.

It can be seen that in the authorization of the first type of configuration, the terminal device receives the authorization configuration information, and can immediately use the transmission parameters configured by the authorization configuration information to transmit data on the configured resources; while in the authorization of the second type of configuration, the terminal After the device receives the authorization configuration information, it cannot immediately use the transmission parameters configured by the authorization configuration information to transmit data on the configured resources, but can only perform data transmission when the network-side device is activated.

5) Activation or release of configured authorization. In order to support a variety of services with different requirements for delay and reliability, NR also supports the configuration of multiple sets of authorization configuration information on the same bandwidth part, and different sets of authorizations The configuration information is distinguished by index or identification. For example, the network side device will create an index or identification for each set of configured authorization, and carry the index or identification in the configured authorization configuration information and send it to the terminal device. It should be understood that the index or identification can be numbered starting from 0 or starting from 1.

When the network side device is configured with multiple sets of authorizations for the second configuration, the activation and release of the authorizations for the multiple second configurations will be involved.

One way to activate the authorization of the second type of configuration is that the network side device sends the downlink control information (DCI) for activating the configuration authorization to the terminal device. For example, the DCI may be scrambled by the first RNTI, such as CS-RNTI, and the new data indicator (NDI) field of the DCI is set to 0, and the DCI carries an index or an authorization for indicating the second type of configuration. An identifier to indicate the authorization to activate the index or identify the corresponding second type of configuration. However, this method can only activate one set of authorizations for the second configuration among multiple sets of authorizations for the second configuration. In some embodiments, the authorized DCI used to activate the second type of configuration is also referred to as activated DCI. The domain of the index or identifier used to indicate the authorization of the second type of configuration in the activated DCI is called the activated domain. For example, when the value indicated by the activation domain is 5, it means the authorization of the second type of configuration with the activation index or the identifier of 5; when the value indicated by the activation domain is 6, it means the authorization of the second type of configuration with the activation index or the identifier of 6 . In some embodiments, the active field may reuse an existing field in the DCI, such as the HARQ process number (HARQ process number) field.

The difference from the activation of the authorization of the second type of configuration is that the release of the authorization of the second type of configuration can support the release of multiple sets of authorization of the second type of configuration, and can also support the release of multiple authorizations of the second type of configuration. Part of the authorization of the second type of configuration in the authorization of the second type of configuration, that is, supports joint release.

For example, to release a set of authorizations for the second type of configuration, the network side device sends the DCI used to release the authorization for the second type of configuration to the terminal device. Since the DCI is used to release the authorization for the second type of configuration, the DCI can also become a release DCI. The released DCI can be scrambled by CS-RNTI, and the NDI field of the released DCI is set to 0. The DCI carries an index or identifier for indicating the authorization of the second type of configuration to indicate the release of the index or identifier corresponding to the second Authorization for class configuration. However, this method can only release one set of authorization for the second configuration among multiple sets of authorization for the second configuration. It should be understood that releasing the index or identifier field used to indicate the authorization of the second type of configuration in the DCI is called the release field. In some embodiments, the release field in the release of the DCI may reuse the existing field in the DCI, for example, the HARQ process number (HARQ process number) field. For example, when the value indicated by the release field is 5, it means the authorization to release the second type of configuration with the index or identifier as 5; when the value indicated by the release field is 6, it means the authorization to release the second type of configuration with the index or identifier as 6 .

For example, to release multiple sets of authorization for the second type of configuration, the network side device can configure a release state set, which contains one or more states (state or entry), and each state is associated with one or more sets of the second type of configuration. Authorization. Which set or sets of authorizations for the second type of configuration are specifically released is indicated by the DCI issued by the network side device. For example, the DCI may include a field for indicating status, which is also called a release field, which is determined by the value indicated by the release field. Which second type of configuration authorization should be released. For example, when the value indicated by the release field is 5, it means that all authorizations of the second type of configuration associated with the state of the release state are 5, or if the value indicated by the release field is 6, it means that the state of the release state is 6 Authorization for all second type configurations.

The difference between the activation of the authorization of the second type of configuration is that the release of the authorization of the second type of configuration also needs to meet the release verification (validation) condition, for example, the condition may be the redundancy version (RV) in the DCI. The field is set to all 0, the modulation and coding scheme (MCS) field and the frequency domain resource assignment (FDRA) field are set to all 1.

5) Resource allocation type. There are two types of authorized resource allocation for the second type of configuration. The two resource allocation types are resource allocation type 0 (resource allocation type 0) and resource allocation type 1 (resource allocation type 1). The network-side device can configure the resource allocation type for authorization of the second type of configuration through RRC signaling. In addition, the network-side device can also use RRC signaling to configure the resource allocation type of the authorization configuration of the second type of configuration to be dynamic, that is, the specific resource allocation type used by the authorization of the second type of configuration ( Resource allocation type 0 or resource allocation type 1) is additionally indicated by the network side device through DCI. For example, the network side device sends the authorized DCI used to activate the second type of configuration, the DCI is scrambled by the CS-RNTI, and the NDI field of the DCI is set to 0, and the DCI needs to meet the activation validation conditions, such as the RV in the DCI The domain is set to all 0s. Specifically, the value of the FDRA field in the DCI is used to indicate the resource allocation type. For example, the most significant bit (MSB) of the FDRA field can be used to indicate the resource allocation type. For example, the value of the MSB is 0, which indicates the resource allocation. The allocation type is type 0, and the value of the MSB is 1, indicating that the resource allocation type is type 1.

For resource allocation type 0, the FDRA domain is a bitmap, where each bit represents one or more frequency domain resource blocks. If the bit value is 1, it means that the corresponding frequency domain resource block is allocated to the terminal device; if the bit value is 0, it means that the corresponding frequency domain resource block is not allocated to the terminal device, so each bit in the FDRA domain Both are 0, which can be considered as an invalid frequency domain resource configuration. For resource allocation type 1, the FDRA field indicates the starting position of the frequency domain resource block allocated to the terminal device and the number of resource blocks. Therefore, each bit in the FDRA field has a value of 1, which can be considered as an invalid frequency domain resource. Configuration. For the dynamic resource allocation type, when the MSB of the FDRA domain is 0, it represents the resource allocation type 0. At this time, the remaining bits of the FDRA domain are all 0, which is considered an invalid frequency domain resource configuration. Therefore, the bits of the FDRA domain All 0s indicate an invalid frequency domain resource allocation; when the MSB of the FDRA domain is 1, it represents the resource allocation type. At this time, the remaining bits of the FDRA domain are all 1s, which is considered an invalid frequency domain resource configuration. Therefore, FDRA The bits of the field are all 1, indicating invalid frequency domain resource allocation.

6) The terms "system" and "network" in the embodiments of this application can be used interchangeably. "Multiple" refers to two or more than two. In view of this, "multiple" may also be understood as "at least two" in the embodiments of the present application. "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one refers to including one, two or more, and does not limit which ones are included. For example, including at least one of A, B, and C, then the included can be A, B, C, A and B, A and C, B and C, or A and B and C. "And/or" describes the association relationship of the associated objects, indicating that there can be three types of relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone. In addition, the character "/", unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

Unless otherwise stated, ordinal numbers such as “first” and “second” mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority, or importance of multiple objects.

Some concepts related to the embodiments of the present application are introduced as above, and the technical features of the embodiments of the present application are introduced below.

As mentioned above, whether it is to activate the authorization of the second type of configuration or release the authorization of the second type of configuration, the NDI field in the DCI sent by the network side device is set to 0, and the DCI is scrambled by the CS-RNTI. Therefore, for the terminal device, when the terminal device receives DCI and determines that the DCI is scrambled by CS-RNTI, and the NDI field in the DCI is set to 0, the terminal device needs to determine whether the DCI is a released DCI, that is, determine the DCI Whether to release the authorization of the second type of configuration. Refer to Table 1. The current judgment method is that when the terminal device receives the DCI scrambled by CS-RNTI format 0_0/0_1/0_2 and the NDI field is set to 0, the terminal device validates the DCI judge. If the RV field in the DCI is set to all 0, the MCS field is set to all 1, and the FDRA field is set to meet Table 1, the terminal device considers the DCI to be a valid release of the DCI.

Table 1

It can be seen that currently on the basis of the RV domain and the MCS domain, the FDRA domain is used to determine the effectiveness of DCI release. This can reduce the probability of false alarms, that is, reduce the probability of misjudging a certain DCI as the release of DCI, and increase Validate reliability.

However, the premise of using the FDRA domain to improve the validation performance of the released DCI is that the value set in the FDRA domain in the released DCI is an invalid value, that is, the value will not be used to activate the DCI, otherwise the terminal may not be able to judge the reception according to the FDRA domain Is the DCI used for activation or release?

However, in the prior art, the value of the released FDRA field in the DCI is determined according to the authorized resource allocation type of the released second type of configuration. Since the resource allocation type is configured separately for each authorization of the second type configuration, different authorizations of the second type configuration may be configured to different resource allocation types. For example, the network side device simultaneously configures and activates 3 sets of authorizations of the second type configuration on an activated BWP for the terminal device. Assume that the corresponding indexes of the 3 sets of authorizations of the second type configuration are 3, 4, and 5 respectively, and The authorized resource allocation type of the second type configuration with index 3 is type 0, the authorized resource allocation type of the second type configuration with index 4 is type 1, and the authorized resource allocation type of the second type configuration with index 5 It is a dynamic type. If the release of DCI is used to release multiple sets of authorizations for the second type of configuration, that is, the network side device configures the release state set through RRC signaling, for example, a certain state of the configuration is associated with the index of the authorization of the aforementioned three sets of second type of configurations, then When the release field in the release DCI indicates this state, it means that the network side releases the authorizations of the three second-type configurations with indexes 3, 4, and 5 at the same time. In view of this situation, that is, the released three sets of authorizations of the second type of configuration correspond to different resource allocation types. Obviously, the network side cannot determine the value of the FDRA domain according to the authorized resource allocation types of the released second type of configuration, that is, It is currently determined that the value of the FDRA field in the released DCI cannot be used in the scenario of joint release.

On the other hand, the value of the released FDRA field in the DCI determined according to the authorized resource allocation type of the second type of configuration to be released may be a valid value for frequency domain resource allocation. For example, in a joint release scenario, the value of the HPN field in a certain DCI is 2, indicating the state of an authorization that is associated with multiple sets of second configuration (for example, two sets of second For authorization of class configuration, the resource allocation types are all type 1). At this time, the value of the FDRA field is determined according to the authorized resource allocation type of the released second type of configuration, and the determined value should be all 1s, because all 1s are for the two sets of second type configurations with indexes 6 and 7 In terms of authorization, they are all invalid frequency domain resource allocations. However, in an activation scenario, the value of the HPN field in the DCI may also be 2. At this time, the HPN field indicates the index of the authorization of the second type of configuration to be activated (for example, the authorization of the second type of configuration with an index of 2, which The resource allocation type is type 0), and the authorized resource allocation type of the second type of configuration with an index of 2 is type 0, so all 1s are effective frequency domain resource allocation. In this case, no matter whether DCI is activated or DCI is released, the HPN field and the FDRA field may have the following combinations: the HPN field takes a value of 2, and the bits of the FDRA field are all ones. At this time, the terminal device cannot distinguish whether the received DCI is used for activation or release according to the FDRA domain, and thus cannot use the FDRA domain to improve the verification performance of the released DCI.

Taking into account the above problems, the embodiments of this application consider that in order to support the application of the authorized joint release of the second type of configuration and use the FDRA field to improve the reliability of authentication, it is necessary to make it clear that the value of the FDRA field used for release is not an active valid value. . Therefore, in the embodiment of the present application, in the DCI used for joint release, the value of the FDRA field is determined according to the authorized resource allocation type of the second configuration whose index is the same as the value of the HPN field, for example, the network side device sets it In this way, the terminal device can distinguish whether the received DCI is used for activation or release according to the FDRA field, so that the FDRA field can be used to improve the verification performance of DCI release.

Please refer to FIG. 2, which is an application scenario applied by the embodiment of this application, or a network architecture applied by the embodiment of this application. Figure 2 includes network equipment and 6 terminal equipment. It should be understood that the number of terminal equipment in Figure 2 is only an example, and may be more or less. The network architecture may also include other network equipment, such as The wireless relay device and the wireless backhaul device are not shown in FIG. 2. A network device is an access device that a terminal device accesses to the network via wireless, and may be a base station. Among them, network equipment corresponds to different equipment in different systems, for example, in the fourth-generation mobile communication technology (4th-generation, 4G) system, it can correspond to eNB, and in 5G system, it can correspond to gNB; these 6 terminal devices can be cellular phones. , Smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable devices for communicating on wireless communication systems, and all of them can be connected to network devices.

The terminal device in the embodiment of the present application may be a terminal device in a connected state, or a terminal device in a non-connected state (such as an inactive INACTIVE state). The embodiments of the present application can be applied to uplink signal transmission, can also be applied to downlink signal transmission, and can also be applied to D2D signal transmission.

For example, the MCS sends the uplink data to the terminal device, and the network device receives the uplink data from the terminal device. The data of the terminal device.

The embodiment of the present application provides a communication method. Please refer to FIG. 3, which is a flowchart of the method. In the following introduction process, the application of this method to the network architecture shown in FIG. 2 is taken as an example. In addition, the method can be executed by two communication devices, for example, the first communication device and the second communication device. For ease of introduction, in the following, the method is executed by a network device and a terminal device as an example, that is, an example is that the first communication device is a terminal device and the second communication device is a network device. For example, the terminal device in the following may be any one of the six terminal devices in FIG. 2, and the network device in the following may be the network device in FIG. 2. It should be noted that the embodiments of the present application only take execution through network equipment and terminal equipment as an example, and are not limited to this scenario.

The process of the communication method provided by the embodiment of the present application is described as follows.

S301. The network device sends configuration information to the terminal device, and the terminal device receives the configuration information. The configuration information is used to configure a release state set. The release state set includes one or more states, and each state is associated with one or more sets of first states. Authorization of the second type of configuration.

S302. The network device configures the value of the FDRA field in the DCI according to the value of the first field in the DCI used for activation.

S303. The network device sends the DCI to the terminal device, and the terminal device receives the DCI, and the first field of the DCI indicates the first state. It should be understood that the first state is a state in the release state collection, and the first state is associated with one or more sets of authorizations of the second type of configuration.

Here, the first field can be considered as a field of DCI. When DCI is used to activate the authorization of the second type of configuration, the first field can be considered as the activation field, which is used to indicate the authorization of the activated second type of configuration; when the DCI is used to release the authorization of the second type of configuration. For the authorization of the second type of configuration, the first domain can be regarded as the release domain, which is used to indicate the authorization of the released second type of configuration. For example, DCI is used to release multiple sets of authorization of the second type of configuration, then the first domain can be used for Indicates the state in the release state set. In some embodiments, the first domain may be the HPN domain in the DCI or the HARQ process number domain. In the following, the first domain is the HPN domain as an example. It should be noted that in the embodiments of the present application, the value of a domain may also be understood as the value carried by the domain in some embodiments.

The terminal device receives the DCI, and before performing verification, it needs to determine whether the DCI is used to activate the authorization of the second type of configuration or to release the authorization of the second type of configuration, so as to further improve the verification performance of releasing the DCI.

For the scenario of joint release, the network device can send configuration information to the terminal device, and the configuration information can be used to configure the authorization to release multiple sets of the second type of configuration. For example, the configuration information is used to configure a release state set. The release state set includes one state or multiple states, and each state can be associated with a set of authorizations for the second type of configuration or multiple sets of authorizations for the second type of configuration. Specifically, which set or sets of authorizations for the second type of configuration are released, the network device can additionally indicate through the DCI. For example, the value indicated by the first field in the DCI is 5, which means that all authorizations of the second type of configuration associated with the state of the 5 state are released.

The resource allocation types of authorizations for multiple sets of type 2 configurations associated with the same state may be the same. If according to the prior art, the value of the FDRA field in the activated DCI is determined according to the authorization of the released type 2 configuration, the determined FDRA is The value of the domain may be valid for both the authorization to activate the second type of configuration and the authorization to release the second type of configuration. For example, two sets of authorizations of the second type configuration with the status association index of 6 and 7 in the status 5, and the resource allocation types of the authorizations of the two second types of configurations are both 1, then the FDRA for releasing the DCI is all 1. If DCI is used for the authorization of the second type of configuration with the activation index of 5, FDRA all 1 is effective for the activation of the authorization of the second type of configuration, which causes the network equipment or terminal equipment to be unable to distinguish whether the DCI is used for activation or release. .

The resource allocation types of authorizations for multiple sets of second-type configurations associated with the same state may also be different. If according to the prior art, the value of the FDRA field in the activated DCI is determined according to the released authorization of the second-type configuration, because there are multiple sets of authorizations. The resource allocation types of authorizations of the second type of configuration are different, and it is impossible to determine which set of authorizations of the second type of configuration to be used. That is, the current method of determining the value of the FDRA domain is not applicable to the scenario of joint release.

Therefore, it is necessary to make it clear that the value set in the FDRA field in the release of the DCI is an invalid value, that is, the value will not be used to activate the DCI. However, for the joint release scenario, how to configure the value of the FDRA field in the release of the DCI is not defined yet .

In the scenario of joint release, the embodiment of the present application may specify the value of the FDRA field in the DCI to be released, so that when the value of FDRA indicates activation, it may indicate invalid release, or when the value of FDRA indicates invalid activation When the time, it can indicate the effective release. In this way, it is possible to distinguish whether the received DCI is used for activation or release according to the FDRA domain, so that the FDRA domain can be used to improve the validation performance of the DCI release.

As a possible implementation manner, the network device may configure the value of the FDRA field in the DCI according to the value of the HPN field in the DCI used to release the authorization of the second type of configuration. For ease of description, hereinafter, the authorized DCI used to activate the second type of configuration is referred to as activated DCI, and the authorized DCI used to release the second type of configuration is referred to as released DCI.

The HPN domain is used to indicate the authorization of the activated second type of configuration when activating the DCI, and is used to indicate the authorization of the released second type of configuration in the release of the DCI, but the HPN domain is different in specific indication methods. In activating DCI, the HPN field directly indicates a specific set of authorization of the second type of configuration to be activated, for example, indicates the index of the authorization of the second type of configuration to be activated. For example, the authorization index of the second type of configuration configured by the higher layer is 1-16, the HPN field can occupy 4 bits, the value of the HPN field is 0-15, and a value in 0-15 corresponds to a set of authorization of the second type of configuration index of. Exemplarily, the value of the HPN domain is 0, which corresponds to the authorization indicating the second type of configuration with an index of 1; the value of the HPN domain is 1, which corresponds to the authorization indicating the second type of configuration with the index of 2, and so on. In some embodiments, the index of the authorization of the second type of configuration at a higher level can also be 0-15. In this case, the value of the HPN field is 0, which corresponds to the authorization of the second type of configuration with an index of 0; the HPN field The value of is 1, corresponding to the authorization indicating the second type of configuration with index 1, and so on. It should be understood that if there is an authorization index for a certain second type of configuration that is the same as the value of the HPN field in the activated DCI, that is, there is an authorization to activate the second type of configuration indicated by the DCI. If there is no authorization index of the second type of configuration that is the same as the value of the HPN field in the activated DCI, that is, the value of the HPN field in the activated DCI is different from the index of any set of authorization of the second type of configuration, then no There is a corresponding authorization for the second type of configuration, and it can be considered that the activation of the DCI is wrong. In this case, the network device can discard the activation of the DCI.

In the release of the DCI, the HPN field can directly indicate a state in the release state set configured by the higher layer, and the authorization of one or more sets of the second type of configuration associated with the state is the authorization of the second type of configuration to be released.

It should be noted that in the embodiment of the present application, in the DCI used to release the authorization of the second type of configuration, the HPN field is used to indicate a state. Specifically, if the network device does not configure the release state set for the terminal device, the HPN field in the release DCI indicates the authorized index of the second type of configuration; if the network device configures the release state set for the terminal device, release the HPN in the DCI The domain indicates the status, not the authorized index of a certain set of second type configuration. In the case that the HPN domain indicates a status, although the function of the HPN domain is not used to indicate a specific set of authorization for the second type of configuration, there may also be a specific set of authorization for the second type of configuration and HPN. The value of the domain corresponds, or the value of the HPN domain will also correspond to a specific set of authorization for the second type of configuration. Here, there is a specific set of authorization for the second type of configuration corresponding to the value of the HPN field. For example, when the index of the authorization for the second type of configuration is numbered from 0, the value of the HPN field corresponds to one. A set of authorizations of the second type of configuration whose index is the same as the value of the HPN, or when the index of the authorization of the second type of configuration is numbered starting from 1, the value of the HPN field corresponds to the first set of indexes that are the same as the value of HPN after subtracting 1. Authorization of the second type of configuration. In other words, when the terminal receives DCI and the DCI is scrambled by CS-RNTI, and the NDI value is 0, the terminal cannot determine that the DCI is an authorization for activating a certain set of type 2 configurations based on this information. It is still used to release a certain set or multiple sets of authorization for the second type of configuration, that is, the terminal cannot determine whether the HPN field in the DCI is used to indicate a certain set of authorization for the second type of configuration to be activated at this time, or for Indicates a status. Therefore, in the release of the DCI, the authorization of a specific type 2 configuration corresponding to the value of the HPN domain can also be understood as assuming that when the DCI is used to activate the authorization of the second type configuration, the value of the HPN domain is Authorization of the second type of configuration indicated.

In addition, it should be noted that in the embodiment of the present application, in the DCI used to release the authorization of the second type of configuration, the HPN field is used to indicate a state. In this case, there may not be a specific set of authorization for the second type of configuration corresponding to the value of the HPN field, or the value of the HPN field may not correspond to any specific set of authorization for the second type of configuration. Specifically, for example, when the authorization index of the second type of configuration is numbered from 0, the value of the HPN field is different from the index of any set of authorization of the second type of configuration, or when the authorization of the second type of configuration is indexed When the index number starts from 1, the value of the HPN field plus 1 is different from the authorized index of any set of the second type of configuration. It can also be understood that when the DCI is used to activate the authorization of the second type of configuration, the value of the HPN field does not indicate any set of authorization for the second type of configuration, or the value of the HPN field indicates that the authorization of the second type of configuration does not Configured by the network side device.

The embodiment of this application aims at how to configure the value of the FDRA field used to release the DCI to be applicable to the scene of joint release. Regarding whether the value of the HPN field in the released DCI is the same as the authorized index of a certain set of second type configuration, the value of the FDRA field in the released DCI of the network device is different. The following respectively describes how the network device configures the release of the value of the FDRA field in the DCI when there is a certain set of authorization for the second type of configuration corresponding to the value of the HPN field in the release of the DCI; and there is no set of second type of configuration When the authorization corresponds to the value of the HPN field in the release of the DCI, how the network device configures the value of the FDRA field in the release of the DCI. It should be understood that a certain set of authorizations for the second type of configuration may be one set of authorizations for the second type of configuration among multiple sets of authorizations for the second type of configuration configured by the network device for the terminal device.

In the first case, there is a certain set of authorization for the second type of configuration corresponding to the value of the HPN field in the released DCI, for example, the value of the HPN field in the released DCI is the same as the index of the authorization of a certain second type of configuration. The network device can configure to release the value of the FDRA field in the DCI according to the authorized resource allocation type of the second type of configuration whose index is the same as the value of the HPN field in the released DCI, and the authorized resource allocation type of the second type of configuration is different. The value of the FDRA field in the configured DCI is also different, and the following examples are introduced.

In the first example, if the authorized resource allocation type of the second type of configuration is type 0, the network device may configure the value of the FDRA field to be all 0s.

For example, the value of the HPN field in the released DCI is 5, and there is an authorization of the second type of configuration with an index of, for example, 5, and the resource allocation type of the authorization of the second type of configuration is 0. The network device configures the release state set. The configured release state set includes state 5, and state 5 is associated with two sets of authorizations of the second type of configuration. The indexes of the authorizations of the two sets of second type of configuration are 7 and 8, and the two sets of authorizations The authorized resource allocation type of the second type of configuration is 1. If according to the prior art, the network device determines the value of the FDRA field according to the authorized resource allocation type of the second type of configuration to be released, then the determined value of the FDRA field is all ones. However, the value of the FDRA domain is all 1, which is an effective frequency domain resource allocation for the authorization of the second type of configuration with an index of 5. Therefore, it is used to activate the DCI of the authorization of the second type of configuration with the index of 5. , It may happen that the value of the HPN field is 5 and the value of the FDRA field is all 1. In this case, in both the activated DCI and the released DCI with the HPN field value of 5, the value of FDRA may be all 1, so the terminal device cannot distinguish the function of the DCI according to the FDRA field.

In the embodiment of the present application, if the value of the HPN field is 5 and there is an authorization of the second type of configuration whose index is 5, for example, the resource allocation type of the authorization of the second type of configuration is 0. According to the method provided in the embodiment of the present application, the network device can configure the value of the FDRA field in the released DCI to be all 0 according to the authorized resource allocation type of the second configuration with the index of 5, that is, 0. It should be understood that the network device configures the DCI to release the authorization of the second type of configuration. In addition to configuring the value of the FDRA field in the DCI, for example, the value of the MCS field and the value of the RV field in the DCI may also be configured. For example, the network device configuration can configure the value of the MCS field in the DCI to be all 1s and the value of the RV field to all 0s.

For the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is the authorized index of a certain set of second type configuration configured by the terminal device When the value of the HPN field is the same as the value of the HPN field in the DCI, and the authorized resource allocation type of the certain set of second type configuration is 0, and the value of the FDRA field is not all 0, then the terminal device can determine that the DCI is not used to release the second Authorization for class configuration. On the contrary, if the terminal device determines that the authorized index of a certain set of second configuration configured by the network device for the terminal device is the same as the value of the HPN field in the DCI, and the authorized resource allocation type of the certain set of second configuration is 0 , And it is determined that the value of the FDRA field is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

For example, when the terminal device determines that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is the authorized index of a certain set of second type configuration configured by the terminal device The value of the HPN field in the DCI is the same. The authorized resource allocation type of the second type of configuration is 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is All 1, the value of the RV field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the second types associated with the status indicated by the HPN field in the DCI. Authorization for class configuration.

Alternatively, in addition to configuring the value of the FDRA field in the DCI, the value of the MCS field in the DCI, and the value of the RV field in the DCI, the network device may also configure the value of the UL-SCH field in the DCI. For example, the network device configuration can configure the value of the MCS field in the DCI to be all 1s, the value of the RV field to all 0s, and the value of the UL-SCH field in the DCI to all 0s. For the terminal device, if it is determined that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain set of second type configuration configured by the terminal device The index of the authorization is the same as the value of the HPN field in the DCI, the authorized resource allocation type of this certain set of second configuration is 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the MCS in the DCI The value of the field is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0. Then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device It is possible to release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI. It can be seen that this solution can be applied to the scenario of joint release, that is, the value of the FDRA field in the released DCI is explicitly configured according to the value of the HPN field in the released DCI. At the same time, the solution enables network equipment and terminal equipment to distinguish the functions of DCI, thereby improving the validation performance of DCI release.

In the second example, if the authorized resource allocation type of the second type of configuration is type 1, the network device may configure the value of the FDRA field to be all 1.

For example, the value of the HPN field in the release DCI is 5, and there is an authorization of the second type of configuration with an index of 5, and the resource allocation type of the authorization of the second type of configuration is 1. The network device configures the release state set. The configured release state set includes state 5, and state 5 is associated with two sets of authorizations of the second type of configuration. The indexes of the authorizations of the two sets of second type of configuration are 7 and 8, and the two sets of authorizations The authorized resource allocation type of the second type of configuration is 0. If according to the prior art, the network device determines the value of the FDRA field according to the authorized resource allocation type of the second type of configuration to be released, then the determined value of the FDRA field is all 0s. However, the value of the FDRA domain is all 0, which is an effective frequency domain resource allocation for the authorization of the second type of configuration with an index of 5. Therefore, it is used to activate the DCI of the authorization of the second type of configuration with an index of 5. , It may also happen that the value of the HPN field is 5 and the value of the FDRA field is all 0. In this case, in both the activated DCI and the released DCI with the HPN field value of 5, the value of FDRA may be all 0s, so the terminal device cannot distinguish the function of the DCI according to the FDRA field.

In the embodiment of the present application, if the value of the HPN domain is 5 and there is an authorization of the second type of configuration whose index is 5, for example, the resource allocation type of the authorization of the second type of configuration is 1. According to the method provided in the embodiment of the present application, the network device can configure the release of the value of the FDRA field in the DCI to be all 1s according to the authorized resource allocation type of the second configuration with the index of 5, that is, 1.

For the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is authorized for a certain set of type 2 configurations configured by the terminal device The index is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is 1. If it is determined that the value of the FDRA field is not all 1, the terminal device can determine that the DCI is not used to release the first configuration. Authorization of the second type of configuration. On the contrary, if the terminal device determines that the authorized index of a certain set of second type configuration configured by the network device for the terminal device is the same as the value of the HPN field in the DCI, the authorized resource allocation type of the certain set of second type configuration is 1, and If it is determined that the value of the FDRA field is all 1, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

For example, when the terminal device determines that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is the authorized index of a certain set of second type configuration configured by the terminal device The value of the HPN field in the DCI is the same. The authorized resource allocation type of the second type of configuration is 1, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the MCS field in the DCI is all 1. The value of the RV field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the second type associated with the status indicated by the HPN field in the DCI Configured authorization. Or, for another example, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain set of second type configuration configured by the terminal device The authorized index is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is 1, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the MCS field in the DCI The value of is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can Release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI. It can be seen that this solution can be applied to the scenario of joint release, that is, the value of the FDRA field in the released DCI is explicitly configured according to the value of the HPN field in the released DCI. At the same time, the solution enables network equipment and terminal equipment to distinguish the functions of DCI, thereby improving the validation performance of DCI release.

In the third example, if the authorized resource allocation type of the second type of configuration is a dynamic type, the network device may configure the value of the FDRA field to be non-all zeros.

For example, the value of the HPN field in the released DCI is 5, and there is an authorization of a second type of configuration with an index of, for example, 5, and the resource allocation type of the authorization of the second type of configuration is a dynamic type. The network device configuration release state set includes state 5, and state 5 is associated with two sets of authorizations of the second type of configuration, and the indexes of the authorizations of the two sets of second type of configuration are 7 and 8. At this time, in the activated DCI used to activate the authorization of the second type of configuration with the activation index of 5, the value of the FDRA field cannot be all 0s. Therefore, it is used to release the authorization of the second type of configuration associated with the release state 5. In DCI, the FDRA field can be set to all 0s. When the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain set of terminal device configuration The authorized index of the second type of configuration is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is dynamic. If it is determined that the value of the FDRA field in the received DCI is not all 0s, Then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if the terminal device determines that the authorization index of a certain set of second type of configuration configured by the network device for the terminal device is the same as the value of the HPN field in the DCI, The resource allocation type of the authorization of the certain set of second type configuration is dynamic. If it is determined that the value of the FDRA field in the received DCI is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain configuration of the terminal device The authorization index of the second type of configuration is the same as the value of the HPN field in DCI. The authorized resource allocation type of the second type of configuration is dynamic. If the terminal device determines that the value of the FDRA field in the DCI is all 0, And the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release the HPN field in the DCI. Authorization of all second-type configurations associated with the indicated state. Or, for another example, for a terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain set of the terminal device configuration The authorized index of the second type of configuration is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is dynamic. If the terminal device determines that the value of the FDRA field in the DCI is all 0, and the DCI The value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration , The terminal device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI. It can be seen that this solution can be applied to the scenario of joint release, that is, the value of the FDRA field in the released DCI is explicitly configured according to the value of the HPN field in the activated DCI. At the same time, the solution enables network equipment and terminal equipment to distinguish the functions of DCI, thereby improving the verification performance of DCI release.

In a fourth example, if the authorized resource allocation type of the second type of configuration is a dynamic type, the network device may configure the value of the FDRA field to be all ones.

For example, the value of the HPN field in the released DCI is 5, and there is an authorization of a second type of configuration with an index of, for example, 5, and the resource allocation type of the authorization of the second type of configuration is a dynamic type. The network device configuration release state set includes state 5, and state 5 is associated with two sets of authorizations of the second type of configuration, and the indexes of the authorizations of the two sets of second type of configuration are 7 and 8. At this time, in the activated DCI used to activate the authorization of the second type of configuration with the activation index of 5, the value of the FDRA field cannot be all 1s. Therefore, it is used to release the authorization of the second type of configuration associated with the release state 5. In DCI, the FDRA field can be set to all 1s. When the terminal device determines that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a set of configuration for the terminal device The authorized index of the second type of configuration is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is dynamic. If it is determined that the value of the FDRA field in the received DCI is not all 1, Then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the received DCI is all 1, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain configuration of the terminal device The authorization index of the second type of configuration is the same as the value of the HPN field in DCI. The authorized resource allocation type of the second type of configuration is dynamic. If the terminal device determines that the value of the FDRA field in the DCI is all 1, And the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release the HPN field in the DCI. Authorization of all second-type configurations associated with the indicated state. Or, for another example, for a terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if the terminal device determines that the network device is a certain set of the terminal device configuration The authorized index of the second type of configuration is the same as the value of the HPN field in the DCI. The authorized resource allocation type of the second type of configuration is dynamic. If the terminal device determines that the value of the FDRA field in the DCI is all 1, and the DCI The value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration , The terminal device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI. It can be seen that this solution can be applied to the scenario of joint release, that is, the value of the FDRA field in the released DCI is explicitly configured according to the value of the HPN field in the activated DCI. At the same time, the solution enables network equipment and terminal equipment to distinguish the functions of DCI, thereby improving the validation performance of DCI release.

It should be understood that the third and fourth examples above can also be considered that when the authorized resource allocation type of the second type of configuration is dynamic, the system or standard may define the value of the FDRA field in the release DCI to be all 0s or all 1s. , Or release the value of the FDRA field in the DCI by default, all 0s or all 1s.

In the second case, there is no authorization for a certain set of second type configuration that corresponds to the value of the HPN field in the released DCI. For example, the value of the HPN field in the released DCI is different from the index of any set of authorization for the second type of configuration. same.

Exemplarily, the network device may be configured to release the value of the FDRA field in the DCI to all 0s. For the terminal device, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if it is determined that the value of the FDRA field in the DCI is not all 0, then the terminal device It can be determined that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the received DCI is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI, and the value of the NDI field of the DCI is 0, the value of the HPN field in the DCI is released with any set of values. The authorized indexes of the second type of configuration are different. If the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 0, then The terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, for another example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI, and the value of the NDI field of the DCI is 0, the value of the HPN field in the DCI is released with any set of second The authorized indexes of the class configuration are different. If the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the RV field in the DCI is all 0. The value of the UL-SCH field is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI .

Exemplarily, the network device may configure the value of the FDRA domain to be all ones. For the terminal device, when the terminal device determines that the received DCI is scrambled by the CS-RNTI, and the value of the NDI field of the DCI is 0, the value of the HPN field in the DCI and any set of authorization of the second type configuration are released If it is determined that the value of the FDRA field in the DCI is not all 1, then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if the value of the FDRA field in the received DCI is determined If it is all 1, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI and the value of the NDI field of the DCI is 0, the value of the HPN field in the DCI is released and any one The authorization indexes of the second set of configurations are not the same. If the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 0, Then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, for another example, for the terminal device, if it is determined that the received DCI is scrambled by the CS-RNTI, and the value of the NDI field of the DCI is 0, if the terminal device determines that the value of the FDRA field in the DCI is all 1s , And the value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the second type With the authorization of configuration, the terminal device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI.

It should be understood that if the value of the HPN field in the released DCI is not the same as the authorized index of any set of the second type of configuration, for the network side, the value of the FDRA field in the released DCI can be defaulted or defined by the system or standards. All 0, relatively speaking, for the terminal side, if the value of the FDRA field in the received DCI is not all 0, then the DCI is not used to release the authorization of the second type of configuration. Of course, in some embodiments, if the value of the HPN field in the released DCI is not the same as the index of any set of authorization of the second type of configuration, for the network side, the default or system-defined or standard-defined release of the DCI can be The value of the FDRA field is all 1, relatively speaking, for the terminal side, if the value of the FDRA field in the received DCI is not all 1, then the DCI is not used to release the authorization of the second type of configuration.

As another possible implementation manner, unlike the above-mentioned network device configured to release the value of the FDRA field in the DCI according to the value of the HPN field in the release DCI, please refer to FIG. 4, based on the same inventive concept, the embodiment of the present application provides a first Two communication methods, this method is applied to the network architecture shown in FIG. 2 as an example. In addition, the method can be executed by two communication devices, for example, the first communication device and the second communication device. For ease of introduction, in the following, the method is executed by a network device and a terminal device as an example, that is, an example is that the first communication device is a terminal device and the second communication device is a network device. For example, the terminal device in the following may be any one of the six terminal devices in FIG. 2, and the network device in the following may be the network device in FIG. 2. It should be noted that the embodiments of the present application only take execution through network equipment and terminal equipment as an example, and are not limited to this scenario.

In this method, the network device can release the value of the FDRA field in the DCI according to at least one set of authorized resource allocation types associated with the state indicated by the HPN in the release DCI. The specific process is described as follows.

S401. The network device sends configuration information to the terminal device, and the terminal device receives the configuration information. The configuration information is used to configure a release state set. The release state set includes one or more states, and each state is associated with one or more sets of first states. Authorization of the second type of configuration.

S402: The network device configures the value of the FDRA field in the DCI to be sent to the terminal device according to at least one set of authorized resource allocation types configured in the second type.

S403. The network device sends the DCI to the terminal device, and the terminal device receives the DCI, and the first field of the DCI indicates the first state. It should be understood that the first state is a state in the release state set, and the first state is associated with one or more sets of authorizations of the second type of configuration.

It should be understood that the foregoing S401 and S301 are consistent, and the foregoing description of S301 may be referred to for details, and the foregoing S402 and S302 are consistent, and the foregoing description of S302 may be referred to for details, which will not be repeated here.

If the release of DCI is used to release multiple sets of authorizations for the second configuration, in a possible scenario, among the authorizations for the multiple second configurations, at least two sets of authorizations for the second configuration have different resource allocation types. In this case, the network device and the terminal device cannot configure the value of the FDRA field according to the authorized resource allocation type of the released second configuration. That is, for the joint release scenario, there is currently no solution how to configure the FDRA field for releasing the DCI.

In the solution provided by the embodiment of the present application, the network device releases the value of the FDRA field in the DCI according to at least one set of authorized resource allocation types associated with the state indicated by the HPN field in the DCI, that is, determines how to configure Release the value of the FDRA field in the DCI to apply to the joint release scenario, so that when a state in the release state set is associated with the authorization of the second type of configuration with different resource allocation types, the FDRA field can be used for verification, thereby improving utilization The performance of the FDRA domain for validation.

Resource allocation types include type 0, type 1, and dynamic type. According to the different types of authorized resource allocation associated with at least one set of second-type configurations associated with the status indicated by the HPN field in the DCI, the network device configuration releases the FDRA field in the DCI. The value is also different. It is assumed here that at least one set of authorization of the second type of configuration associated with the status indicated by the HPN field in the DCI includes authorizations of the second type of configuration with indexes of 6, 7, and 8, for example. The following is an example of how the network device configures and releases the value of the FDRA field in the DCI according to the different types of authorized resource allocation of this at least one set of the second type of configuration, which may include the following situations:

In the first example, if at least one set of authorized resource allocation types of the second type of configuration associated with the status indicated by the HPN field in the DCI includes at least type 0 and does not include type 1, the value of the FDRA field configured by the network device is all 0.

For example, the authorized resource allocation type of the second type of configuration with index 6 is 0, and the authorized resource allocation type of the second type of configuration with indexes of 7 and 8 is the dynamic type, and the network device can be configured to release the value of the FDRA field in the DCI. For all 0s. Or, for example, the authorized resource allocation type of the second type of configuration with index 6 is 0, and the authorized resource allocation type of the second type of configuration with indexes of 7 and 8 is both 1, and the network device can be configured to release the FDRA domain in the DCI The value is all 0s. Or, for example, the authorized resource allocation types of the second type of configurations with indexes of 6, 7 and 8 are all 0, and the network device may be configured to release the value of the FDRA field in the DCI to all 0s. In the above three examples, the network device can configure the value of the FDRA domain to be all 0s.

If the resource allocation type is type 0, and the value of the FDRA field in the DCI is all 0, then for the activated DCI, the activated DCI is invalid, so it can indicate that the DCI is effectively released. For the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if it is determined that the value of the FDRA field in the DCI is not all 0, the terminal device can determine The DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

In some embodiments, the network device configures the DCI to release the authorization of the second type of configuration. In addition to configuring the value of the FDRA field in the DCI, for example, the value of the MCS field and the value of the RV field in the DCI may also be configured. For example, the network device configuration can configure the value of the MCS field in the DCI to be all 1s and the value of the RV field to all 0s.

For the terminal device, if it is determined that the received DCI is scrambled by the CS-RNTI, and the value of the NDI field of the DCI is 0, if the first field of the DCI indicates at least one set of authorization for the second type of configuration The resource allocation type of includes at least type 0 and does not include type 1, and the terminal device determines that the value of the FDRA field in the DCI is all 0, the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is All 0s, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, if the authorized resource allocation type of at least one set of the second configuration indicated by the first field of the DCI includes at least type 0 and does not include type 1, and the terminal device determines that the value of the FDRA field in the DCI is all 0, And the value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the second type of configuration The terminal device can release all the authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI. Through this solution, it can be clarified that in the joint release scenario, the value of the FDRA field is determined according to which resource allocation type in the authorization of multiple sets of second configurations, which can enable network equipment and terminal equipment to distinguish the function of DCI, thereby improving the release of DCI Verify performance.

It should be understood that the authorized resource allocation types of the second type of configurations with indexes 6, 7 and 8 are all 0, and it can also be considered that the network device will not be the second type of configuration with the authorized configuration type of 1 or the dynamic type of resource allocation type. In this case, the network device can be configured to release the value of the FDRA field in the DCI to all 0s. For the terminal device, when it is determined that the value of the FDRA field in the DCI is not all 0s, the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration.

In the second example, if the authorized resource allocation type of at least one set of second type configuration associated with the status indicated by the HPN field in the DCI includes at least type 1, and does not include type 0, the network device configures the value of the FDRA field to be all 1.

For example, the authorized resource allocation type of the second type of configuration with index 6 is 1, and the authorized resource allocation type of the second type of configuration with indexes of 7 and 8 is dynamic type. Or, for example, the authorized resource allocation type of the second type of configuration with an index of 6 is 1, and the authorized resource allocation types of the second type of configuration with indexes of 7 and 8 are both 1. Or, for example, the authorized resource allocation types of the second type of configurations with indexes of 6, 7, and 8 are all 1. In the above three examples, the network device can all configure the value of the FDRA domain to be all ones.

If the resource allocation type is Type 1, and the value of the FDRA field in the DCI is all 1, then for the activated DCI, the activated DCI is invalid, so it can indicate that the DCI is effectively released. When the terminal device determines that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if it is determined that the value of the FDRA field in the received DCI is not all 1, then the terminal device can determine that the DCI is not used To release the authorization of the second type of configuration. Through this solution, it can be clarified that in the joint release scenario, the value of the FDRA field in the DCI is determined to be released according to which resource allocation type in the authorizations of multiple sets of second configurations, so that the network equipment and the terminal equipment can distinguish the functions of the DCI, so that the function of the DCI can be distinguished. Improve the verification performance of the release of DCI.

It should be understood that the authorized resource allocation type of the second type of configuration with indexes 6, 7 and 8 is all 1, and it can also be considered that the network device will not be the second type of configuration. The authorized configuration type is 0 or the dynamic type of resource allocation type. In this case, the network device can be configured to release the value of the FDRA field in the DCI to all 1s. For the terminal device, when it is determined that the value of the FDRA field in the DCI is not all 0s, the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the DCI is All 0s, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI and the value of the NDI field of the DCI is 0, if the first field of the DCI indicates at least one set of first The authorized resource allocation type of the second configuration includes at least type 1, and does not include type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is all 1, and the value of the MCS field in the DCI is all 1. The value of the RV field is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, if the authorized resource allocation type of at least one set of type 2 configurations indicated by the first field of the DCI includes at least type 1, and does not include type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and The value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the second type of configuration Authorization, the terminal device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI.

In the third example, if at least one set of authorized resource allocation types of the second type of configuration associated with the status indicated by the HPN field in the DCI includes at least type 0 and type 1, the network device can allocate authorized resources according to the specific second type of configuration The allocation type determines the value of the FDRA field. In other words, when the resource allocation type of at least one set of authorization of the second type of configuration includes at least type 0 and type 1, in fact, a set of authorization of the second type of configuration is specified, and the network device adopts the second type of authorization by default. The configured authorized resource allocation type is configured to release the value of the FDRA field in the DCI. Compared with the current authorizations involving multiple sets of the second type of configuration, the network device does not know which type of authorized resource allocation type of the second type of configuration is used to configure the value of the FDRA field. Through this scheme, it is specified to configure the FDRA Authorization of the second type of configuration of the value of the domain.

For example, suppose that the authorized resource allocation type of the second type of configuration with index 6 is 0, and the authorized resource allocation type of the second type of configuration with indexes of 7 and 8 is 1. Or, for example, the authorized resource allocation type of the second type configuration with index 6 is 0, the authorized resource allocation type of the second type configuration with index 7 is dynamic type, and the authorized resource allocation type of the second type configuration with index 8 is 0. The type is 1.

In an example of this application, assuming that the authorized index of the specified second type of configuration is 6, that is, the authorized resource allocation type of the specified second type of configuration is 0, and the network device can configure to release the value of the FDRA field in the DCI to all 0.

When the resource allocation type is type 0, if the value of the FDRA field is all 0, then for the activated DCI, the activated DCI is invalid, so it can indicate that the DCI is effectively released. In this case, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, if it is determined that the value of the FDRA field in the DCI is not all 0, the terminal device can determine The DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI and the value of the NDI field of the DCI is 0, if the first field of the DCI indicates at least one set of first The authorized resource allocation types of the second configuration include at least type 1 and type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 1. If the value is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, if the authorized resource allocation type of at least one set of the second configuration indicated by the first field of the DCI includes at least type 1 and type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value in the DCI is The value of the MCS field is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0. Then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal The device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI.

In another example of the embodiment of the present application, assume that the authorized index of the specified second type of configuration is 8, that is, the authorized resource allocation type of the specified second type of configuration is 8, and the network device can configure the value of the FDRA domain to be all 1. .

When the resource allocation type is type 1, and the value of the FDRA field in the DCI is all 1, then for the activated DCI, the activated DCI is invalid, so it can indicate that the DCI is effectively released. Therefore, when the terminal device determines that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if it is determined that the value of the FDRA field in the DCI is not all 1, then the terminal device can determine that the DCI is not used for Release the authorization of the second type of configuration; on the contrary, if it is determined that the value of the FDRA field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

In some embodiments, the authorized index of the second type of configuration specified above may be selected according to a predefined rule. For example, the specified authorized index of the second type of configuration may be the smallest index among the multiple sets of authorized indexes of the second type of configuration configured by the network device for the terminal device, or it may be the multiple sets of second type configured by the network device for the terminal device. The largest index among authorized indexes of the class configuration. For another example, the specified authorized index of the second type of configuration is the smallest index or the largest index in at least one set of authorized indexes of the second type of configuration associated with the state indicated by the HPN field of the DCI. For another example, the authorized index of the specified second type of configuration satisfies the preset rule among the multiple sets of authorized indexes of the second type of configuration configured by the network device for the terminal device; another example is the authorized index of the specified second type of configuration. The index satisfies the preset rule in at least one set of authorized indexes of the second type configuration associated with the status indicated by the HPN field of the DCI. The preset rule may be, for example, the smallest index or the largest index, or other possible preset rules, as long as the FDRA domain in the DCI is released according to the authorized resource allocation type of the second type of configuration determined according to the preset rule When the value of is valid for activating DCI, it is invalid for releasing DCI. On the contrary, when activating DCI is invalid, it is valid for releasing DCI.

It should be understood that if at least one set of authorized resource allocation types of the second type configuration associated with the status indicated by the HPN field in the DCI are the same, for example, including type 0 or type 1, or dynamic type, the network device may also be based on a specific second type. The configured authorized resource allocation type determines the value of the FDRA domain. For the selection of authorization for the specific second type of configuration, reference may be made to the foregoing description, which will not be repeated here.

In the fourth example, if at least one set of authorized resource allocation types of the second configuration associated with the status indicated by the HPN field in the DCI includes at least type 0 and type 1, the network device may determine that the value of the FDRA field in the DCI is released. 0, it can also be understood that the network device releases the value of the FDRA field in the DCI by default to all 0s. For the terminal device, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, at least one set of the second type of configuration associated with the status indicated by the HPN field in the DCI The authorized resource allocation types include at least type 0 and type 1. If the terminal device determines that the value of the FDRA field in the DCI is not all 0, the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if If it is determined that the value of the FDRA field in the DCI is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

In the fifth example, if at least one set of authorized resource allocation types of the second configuration associated with the status indicated by the HPN field in the DCI includes at least type 0 and type 1, the network device may determine to release the value of the FDRA field in the DCI to all 1. It can also be understood that the network device releases the value of the FDRA field in the DCI by default with all 1s. For the terminal device, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, at least one set of the second type of configuration associated with the status indicated by the HPN field in the DCI The authorized resource allocation types include at least type 0 and type 1. If it is determined that the value of the FDRA field in the DCI is not all 1, then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that this The value of the FDRA field in the DCI is all 1, and the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI and the value of the NDI field of the DCI is 0, if the first field of the DCI indicates at least one set of first The authorized resource allocation types of the second configuration include at least type 1 and type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 1. If the value is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, if at least one set of authorized resource allocation types of the second configuration indicated by the first field of the DCI includes at least type 1 and type 0, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the FDRA field in the DCI is all 1. The value of the MCS field is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0. Then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal The device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI.

It should be understood that the foregoing fourth example and fifth example can be considered for the case where the authorized resource allocation type for at least one set of second type configuration includes at least type 0 and type 1, and the network device releases the value of the FDRA field in the DCI by default. 0. The terminal device defaults that when the value of the FDRA field in the DCI is not all 0s, the DCI is not used to release the authorization of the second type of configuration; or, the above fourth and fifth examples can also be considered for at least one set of second The authorized resource allocation type of the class configuration includes at least type 0 and type 1. The network device releases the value of the FDRA field in the DCI by default to all 1, and the terminal device defaults when the value of the FDRA field in the DCI is not all 1. The DCI is not used to release the authorization of the second type of configuration.

In the sixth example, if at least one set of authorized resource allocation types of the second type of configuration associated with the status indicated by the HPN field in the DCI are all dynamic types, the network device may configure to release the value of the FDRA field in the DCI to all 0s. For the terminal device, the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, and the status indicated by the HPN field in the DCI is associated with at least one set of authorization for the second type of configuration When the resource allocation types of are all dynamic types, if it is determined that the value of the FDRA field in the DCI is not all 0s, then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if the DCI is determined to be The value of the FDRA field is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by the CS-RNTI and the value of the NDI field of the DCI is 0, the status indicated by the HPN field in the DCI is at least When the authorized resource allocation types of a set of type 2 configurations are all dynamic types, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the value of the MCS field in the DCI is all 1, and the RV field in the DCI is If the value of is all 0, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, when at least one set of authorized resource allocation types of the second type configuration associated with the status indicated by the HPN field in the DCI are all dynamic types, and the terminal device determines that the value of the FDRA field in the DCI is all 0, and the DCI The value of the MCS field in the DCI is all 1, the value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, The terminal device can release all authorizations of the second type of configuration associated with the status indicated by the HPN field in the DCI.

In the seventh example, if at least one set of authorized resource allocation types of the second type of configuration associated with the status indicated by the HPN field in the DCI are all dynamic types, the network device may configure to release the value of the FDRA field in the DCI to all 1s. For the terminal device, when the terminal device determines that the received DCI is scrambled by CS-RNTI, and the value of the NDI field of the DCI is 0, at least one set of the second type of configuration associated with the status indicated by the HPN field in the DCI When the authorized resource allocation types are all dynamic types, if it is determined that the value of the FDRA field in the DCI is not all 1, then the terminal device can determine that the DCI is not used to release the authorization of the second type of configuration; on the contrary, if it is determined that the DCI is If the value of the FDRA field is all 1, the terminal device can determine that the DCI is used to release the authorization of the second type of configuration.

Similar to the first example, for the terminal device, when it is determined that the received DCI is scrambled by CS-RNTI and the value of the NDI field of the DCI is 0, if at least one set of authorized resources configured in the second type is The allocation types are all dynamic types, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the MCS field in the DCI is all 1, and the value of the RV field in the DCI is all 0, then the terminal device can determine The DCI is used to release the authorization of the second type of configuration, and the terminal device can release all the authorizations of the second type of configuration associated with the state indicated by the HPN field in the DCI. Or, if the authorized resource allocation types of at least one set of the second type of configuration are all dynamic types, and the terminal device determines that the value of the FDRA field in the DCI is all 1, and the value of the MCS field in the DCI is all 1, the value of the MCS field in the DCI is all 1. The value of the RV field in the DCI is all 0, and the value of the UL-SCH field in the DCI is all 0, then the terminal device can determine that the DCI is used to release the authorization of the second type of configuration, and the terminal device can release the indication of the HPN field in the DCI The authorization of all the second type configurations associated with the status.

It should be understood that the sixth example and the seventh example above can be considered that when the authorized resource allocation types for at least one set of the second type of configuration are all dynamic types, the network device is configured to release the value of the FDRA field in the DCI to all 0s, and the DCI Used to release the authorization of the second type of configuration. For the terminal device, when the value of the FDRA field in the DCI is not all 0s, it is determined that the DCI is not used to release the authorization of the second type of configuration; or, the above sixth and seventh examples can be considered for at least one set of second When the resource allocation types of the authorization of the class configuration are all dynamic types, the network device is configured to release the value of the FDRA field in the DCI to all 1, and the DCI is used to release the authorization of the second configuration. For the terminal device, when the value of the FDRA field in the DCI is not all 1, it is determined that the DCI is not used to release the authorization of the second type of configuration.

As yet another possible implementation, when the value of the HPN field in the activated DCI is not the same as the index of any set of authorization of the second type of configuration, that is, when there is no authorization of a certain type of second configuration, the network device can also The value of the FDRA field in the DCI to be released is determined according to the authorized resource allocation type of at least one set of the second type of configuration associated with the release of the DCI. For a specific network device to determine the solution of releasing the value of the FDRA field in the DCI according to at least one set of authorized resource allocation types configured in the second type, refer to the above-mentioned another possible implementation manner, that is, the description of the embodiment in FIG. 4. I won't repeat it here.

In this embodiment of the application, the value of the FDRA field can be determined according to the authorized resource allocation type of a specific set of second configuration corresponding to the value of the HPN field in the released DCI, so that the received data can be distinguished according to the FDRA field. Whether the DCI is used for activation or release, so as to use the FDRA domain to improve the verification performance of releasing the DCI. In addition, the embodiment of the present application can also determine the value of the FDRA field according to one or some resource allocation types of multiple sets of authorizations associated with the state indicated by the HPN field in the DCI. It is applicable to the way to clarify the value of FDRA in the joint release scenario.

In a possible application scenario, the NR system supports a repeated transmission method based on mini time slots, that is, in a time slot, a terminal device is allowed to repeatedly send the same data packet multiple times. This repeated transmission method can reduce the cost of the data packet. Transmission delay. In some embodiments, this repetitive transmission method may also be referred to as PUSCH repetition Type B. In this repetitive transmission method, multiple repetitive nominal repetitive resources allocated to the terminal device by the network device for sending the same data packet multiple times are continuous in the time domain. However, because a nominal repetition resource used to send a repetition may contain unusable symbols (such as downlink symbols, etc.), or contain slot boundaries, a nominal repetition resource will be split into multiple actuals (actual) Repeated resources, where each actual repeated resource is used for one repeated transmission. Therefore, the actual number of repeated transmissions of the terminal device may be greater than the number of nominal repeated resources. Please refer to Figure 5, which is a schematic diagram of the relationship between a nominal duplicate resource and an actual duplicate resource. Figure 5 takes 4 nominal repetitive resources as an example. Since the nominal repetitive resource 2 contains the time slot boundary, the nominal repetitive resource 2 is split into two actual repetitive resources, that is, the actual repetitive resource 2 and Actually repeat resource 3. Since a nominal repetitive resource will be split into multiple actual (actual) repetitive resources, the actual number of repetitive transmissions of the terminal device may be greater than the number of nominal repetitive resources, which requires the determination of the nominal repetitive resource and based on the determined nominal repetitive resource. The actual duplicate resources are used to transmit data.

The embodiment of the present application provides a method for determining the time domain position of a nominal repetitive resource. The method can determine the time domain position of a nominal repetitive resource according to the repetition period of multiple nominal repetitive resources in the time domain, and then can determine the time domain position of the nominal repetitive resource according to the time domain. The location determines the time domain location of the actual repeated resource, that is, determines the actual repeated resource for data transmission.

Please refer to FIG. 6, which is a schematic flow chart of a data sending method provided by an embodiment of this application. The flow of the method is described as follows:

S601. The network device sends configuration information to the terminal device, where the configuration information can be used to configure time domain resources, and the configuration information includes a period parameter, and the period parameter is used to indicate the repetition period of multiple nominal repetitive resources in the time domain.

S602. The terminal device determines the time domain location of the first nominal repeated resource according to the configuration information.

S603: The terminal device determines the time domain position of the first actual repeated resource according to the time domain position of the first nominal repeated resource.

S604: The terminal device sends data on the first actual repeated resource.

When the terminal device sends data, it needs to determine the actual repetitive resource, which needs to determine the time domain position of the nominal repetitive resource. In a possible implementation, the system can predefine the starting time slot and nominal repetition where the start symbol of the nominal repetitive resource is located. The start symbol of the resource in the start time slot, the end time slot where the end symbol of the nominal repetitive resource is located, and the condition that the end symbol of the nominal repetitive resource in the end time slot satisfies, so that the terminal device determines the nominal value based on the condition The time domain location of the duplicate resource.

It should be understood that for the nth nominal repetitive resource in a resource period or repetition bundle, n=0,...,K-1, K is the number of nominal repetitive resources, and K can be determined according to the number of repetitions parameter repK , It can also be determined according to time domain allocation parameters. For example, a network device configures a time domain resource allocation table through high-level signaling. Each row in the table contains the number of repetitions. The time domain resource allocation parameter indicates the used The row number in the table.

Manner 1: In some embodiments, the number of the start time slot of the nth nominal repetition resource satisfies formula (1), and the number of the start symbol of the nth nominal repetition resource in the start time slot satisfies Formula (2), the number of the end time slot of the nth nominal repetitive resource satisfies formula (3), and the end symbol of the number of the nth nominal repetitive resource in the end time slot satisfies the formula (4):

In the above formula (1)-formula (4), P is the period indicated by the period parameter included in the configuration information, m is the number of the period or repetitive bundling, m≥0, L is the number of symbols of a nominal repetitive resource, and N is every The number of symbols in a time slot, n is the number of the nominal repetitive resource, n≥0, and K _s is determined according to the time domain resource offset parameter in the configuration information.

2). K _s is the number of the first time slot in the first frame, and the frame number of the first frame is

The number of the first time slot is mod(M, M1), where M is determined by the time domain resource offset indicated by the time domain resource offset parameter in the configuration information, and M1 is the number of time slots included in one frame.

A variant of

S _m is equal to S.

[(eSFN×M1×N)+(eslot _index ×N)+esymbol _index ]

=mod(M×N+S2+(n+1)×L-1+m×P, 1024×M1×N)

Among them, M is determined by the time domain resource offset of the first nominal repetitive resource, M1 is the number of time slots in a frame, N is the number of symbols in each time slot, and P is the repetition period of multiple nominal repetitive resources. Cycle size, m is the number of the cycle, S1 is the number of the start symbol of the nth nominal repetitive resource, S2 is the number of the end symbol of the nth nominal repetitive resource, L is the number of symbols of a nominal repetitive resource, n is The number of the nominal duplicate resource.
