Technical Field

Background Art

In the 5G industrial internet of things (IIoT), it is necessary to support the transmission of industrial automation (factory automation), transport automation (transport industry), smart power (electrical power distribution) and other services in the 5G system. Based on the transmission requirements of latency and reliability, IIoT introduces the concept of time sensitive communication (TSC).

In order to better serve the TSC service and ensure the transmission service quality (Quality of servic, QoS) of the TSC service, multiple configured grants (configured grant, CG) are introduced for a terminal device. In the related technology, after the network device sends a downlink control message containing activation information or deactivation information of the CG to the terminal device, it can only send another downlink control message containing activation information or deactivation information of the CG after receiving the confirmation information of the CG fed back by the terminal device, and it is impossible to indicate the activation information or deactivation information of multiple CGs at the same time. In addition, because the network device will configure multiple bandwidth parts for the terminal device, but only one bandwidth part (band width part, BWP) is activated at the same time. If the BWP is switched before the confirmation information of the CG fed back by the terminal device, the terminal device cannot determine which BWP to feed back the confirmation information of the CG.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In the 5G industrial internet of things (IIoT), it is necessary to support the transmission of industrial automation (factory automation), transport automation (transport industry), smart power (electrical power distribution) and other services in the 5G system. Based on the transmission requirements of latency and reliability, IIoT introduces the concept of time sensitive communication (TSC).

According to the service characteristics of the TSC network, TSC services are usually highly reliable and low-latency services, and in most scenarios, TSC services appear periodically. Therefore, in order to better serve the TSC service and ensure the transmission service quality (Quality of servic, QoS) of the TSC service, multiple configuration authorizations (configured grant, CG) are introduced for a terminal device. In the R15 scenario, after the network device sends a downlink control message containing CG activation information or deactivation information to the terminal device, it can only send another downlink control message containing CG activation information or deactivation information after receiving the CG confirmation information fed back by the terminal device. In the R16 scenario, after the network device sends a downlink control message for CG activation/deactivation, it can send the next downlink control message for CG activation/deactivation without waiting for the CG confirmation information fed back by the terminal device. In addition, since the network device will configure multiple bandwidth parts for the terminal device, only one bandwidth part (band width part, BWP) is activated at the same time. If the BWP is switched before the terminal device feeds back the confirmation information of the CG, the terminal device cannot determine on which BWP the confirmation information of the CG is fed back.

Therefore, in the related art, it is still impossible to determine how to report the confirmation information of the CG indicated by the downlink control information.

In order to solve the above problems and realize that the terminal device reports downlink control information indicating confirmation information of the first resource, the present application establishes a connection between the identifier of the first resource and the configuration information of the resource, so that after the network device receives the information carrying the identifier of the first resource sent by the terminal device, the understanding of the identifier of the first resource attached to the information can be consistent with that of the terminal device, thereby determining the corresponding resource, and then realizing that the terminal device reports downlink control information indicating confirmation information of the first resource, while also avoiding the inconsistent understanding between the terminal device and the network device caused by the change of BWP. In addition, if there is only CG index in the configuration information of the first resource, then correspondingly, the identifier of the first resource and the CG index correspond one to one.

FIG1 is a schematic diagram of a scenario of a communication method provided by an embodiment of the present application. As shown in FIG1 , a terminal device 101 communicates with a network device 102. When the terminal device 101 receives downlink control information sent by the network device 102, the terminal device 101 activates or deactivates the corresponding resource according to the activation information or deactivation information of the resource in the downlink control information. Subsequently, the terminal device 101 sends feedback information to the network device 102 to feedback whether the activation information or deactivation information of the resource indicated by the downlink control information is received.

Among them, the embodiment of the present application does not limit the number of terminal devices 101 and network devices 102 included in the communication system.

The terminal device 101 may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device 102 may be a mobile phone, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in smart home, etc.

The network device 102 may be, for example, a base station, or various wireless access points, or may refer to a device in an access network that communicates with a user device through one or more sectors on an air interface. The base station may be used to convert received air frames to and from IP packets, as a router between a wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) network. The base station may also coordinate the attribute management of the air interface. For example, the base station may be a base station (base transceiverstation, BTS) in a global system of mobile communication (GSM) or code division multiple access (CDMA), a base station (NodeB, NB) in a wideband code division multiple access (WCDMA), an evolutionary base station (eNB or eNodeB) in a long term evolution (LTE), or a relay station or access point, or a base station gNB in a future 5G network, etc., which are not limited here.

The following uses network devices and terminal devices as examples to describe the technical solutions of the embodiments of the present application in detail with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

FIG2 is a signaling interaction diagram of a communication method provided in an embodiment of the present application. This embodiment relates to a process of how a terminal device and a network device interact. As shown in FIG2 , the method includes:

S201. A terminal device sends first information to a network device. The first information is used to indicate whether the terminal device has received activation information or deactivation information of a first resource indicated by downlink control information. The first information includes an identifier of the first resource.

In this step, when the terminal device receives activation information or deactivation information of the first resource indicated by the downlink control information sent by the network device, it can send first information to the network device to indicate whether the terminal device has received the activation information or deactivation information of the first resource indicated by the downlink control information.

In another implementation, the first information may also indicate an activation state or a deactivation state of the first resource.

The embodiment of the present application does not limit the types of the first information and the first resource, and the first resource may include a configured grant (CG). The first information may be exemplarily a multiple entry CG confirmation, and the multiple entry CG confirmation can only reflect the identification of the first resource.

It should be noted that at least one of the “identities” mentioned in this application can be replaced by an “index”.

In one implementation, before sending the first information, the terminal device also needs to confirm whether it has an available uplink scheduling grant (UL grant). Only when the terminal device has an available UL grant, the first information is sent to the network device.

In one embodiment, the terminal device can also determine the first resource to be confirmed based on the activation or deactivation information indicated by the downlink control information, the identifier of the first resource, and the mapping relationship between the identifier of the first resource and the configuration information of the first resource. Correspondingly, the corresponding bit in the MAC (media access control) CE (control element) is set to determine which bit position in the MAC CE occupied by the first resource, and whether that bit position is 1 or 0, thereby indicating whether the terminal device has received the downlink control information, or whether the CG is activated or deactivated.

S202: The network device determines the first resource according to the identifier of the first resource and a mapping relationship between the identifier of the first resource and configuration information of the first resource.

In this step, after the network device receives the first information sent by the device in the terminal, the network device can determine the first resource according to the identifier of the first resource and the mapping relationship between the identifier of the first resource and the configuration information of the first resource.

In one implementation, if the first resource is a CG, correspondingly, the configuration information of the first resource includes at least one of the following: a serving cell index, a BWP index, and a CG index.

In one implementation, the BWP identifier may be considered in the mapping relationship, or may not be considered.

The embodiment of the present application does not limit the mapping relationship between the CG identifier and the configuration information of the first resource. If the first resource is a CG, in some embodiments, the mapping relationship between the identifier of the first resource and the configuration information of the first resource can be determined according to the order of the service cell identifier and the order of the CG identifier. Among them, the configuration information of the first resource is arranged according to the service cell identifier, and the configuration information of the first resource in each service cell is arranged according to the CG identifier.

In other embodiments, the configuration information of the first resource may also be considered to be arranged according to the service cell identifier, the configuration information of the first resource in each service cell is arranged according to the BWP identifier, and the configuration information of the first resource in each BWP is arranged according to the CG identifier. The above arrangement according to the service cell identifier, BWP identifier and CG identifier may specifically be multiple information in the configuration information of the first resource. When configuring the configuration information of the first resource, the above information is not sorted. When using the above information, the mapping relationship can be determined according to the sorting.

It should be noted that this application does not limit the sorting method, which can be ascending or descending.

Fig. 3 is a schematic diagram of a mapping relationship provided by an embodiment of the present application. As shown in Fig. 3, the serving cell indexes are sorted in ascending order from serving cell 1 to serving cell 3, the CG indexes under the serving cells are also sorted in ascending order, and the identifiers CG0 to CG31 of the first resources are mapped with at least one first resource, that is, the configuration information corresponding to the first resource, in sequence.

In one implementation, the network device may also determine the corresponding CG based on the bits occupied by the identifier of the first resource; or, determine the configuration information of the first resource based on the bits occupied by the identifier of the first resource.

Exemplarily, the network device may also determine the number of bits occupied by the CG information in the confirmation MAC CE according to N. Each CG information occupies 1 bit. N may be a fixed value, such as 32 bits, or, for example, max number of serving cells*max number of CG per BWP.

Exemplarily, if the total number of bits occupied by the mapped first resource in the confirmation MAC CE is less than N, such as 32 bits, the last bit is padded with 0. Specifically, the valid bits can be connected in a way that the valid bits are put together; or, the position of the corresponding first resource or CG in each serving cell can be determined according to the starting position of each serving cell.

In some embodiments, the network device can also determine whether the downlink control information corresponding to the first resource identifier or the CG identifier is received by the terminal device based on the first information sent by the terminal device, or can determine the activation or deactivation status of the first resource.

In the communication method provided in the embodiment of the present application, a network device receives first information sent by a terminal device, the first information is used to indicate whether the terminal device has received activation information or deactivation information of a first resource indicated by downlink control information, and the first information includes an identifier of the first resource. Subsequently, the network device determines the configuration information of the first resource based on the identifier of the first resource and the mapping relationship between the identifier of the first resource and the configuration information of the first resource. In this way, the network device can determine the first resource or the configuration information of the first resource through the identifier of the first resource in the first information, so that after receiving multiple identifiers of the first resource, the network device can ensure that the understanding of the identifier of the first resource is consistent with that of the terminal device, and then can report the confirmation information of the first resource indicated by the downlink control information or the corresponding CG based on the identifier of the first resource.

Based on FIG. 2 , the following describes how a terminal device receives configuration information of a first resource configured by a network device, and how the network device activates or deactivates the first resource. FIG. 4 is a signaling interaction diagram of another communication method provided in an embodiment of the present application. As shown in FIG. 4 , the method includes:

S301. A network device sends configuration information of at least one group of first resources to a terminal device.

In this step, the network device can configure and send configuration information of at least one group of first resources to the terminal device based on the service cell and the bandwidth part.

Exemplarily, for serving cell1, BWP1, the network device may configure three groups of configuration information of the first resource, namely {serving cell index1, BWP index1, CG index1}, {serving cell index1, BWP index1, CG index2}, and {serving cell index1, BWP index1, CG index3}.

Exemplarily, for serving cell 1 and BWP2, the network device may configure two groups of configuration information of the first resource, namely {serving cell index 1, BWP index 2, CG index 1} and {serving cell index 1, BWP index 2, CG index 2}.

Exemplarily, for serving cell2, BWP1, the network device may configure three groups of configuration information of the first resource, namely {serving cell index2, BWP index1, CG index1}, {serving cell index2, BWP index1, CG index2}, and {serving cell index2, BWP index1, CG index3}.

Exemplarily, for serving cell3, BWP1, the network device can configure 4 groups of configuration information of the first resource, namely {serving cell index3, BWP index1, CG index1}, {serving cell index3, BWP index1, CG index2}, {serving cell index3, BWP index1, CG index3}, {serving cellindex3, BWP index1, CG index4}.

S302. The terminal device determines at least one of a serving cell identifier, a BWP identifier and a CG identifier according to configuration information of at least one group of first resources.

In this step, after the terminal device receives the configuration information of the first resource sent by the network device, it determines at least one of the serving cell identifier, the BWP identifier, and the CG identifier. When the terminal device is based on the configuration information of the first resource, it can determine the first resource identifier according to a predefined or preconfigured mapping logic. The above mapping logic has been described in FIG3 and will not be repeated here.

S303. The network device sends downlink control information to the terminal device, where the downlink control information is used to indicate the activation or deactivation of the corresponding CG, or to indicate the activation or deactivation of the corresponding first resource.

In this step, the network device may send downlink control information (DCI) to the terminal device to indicate the corresponding CG activation or deactivation, or to indicate the corresponding first resource activation or deactivation.

The downlink control information may be carried on a physical downlink control channel (PDCCH). The downlink control information may be sent one by one or simultaneously, which is not limited in the embodiment of the present application.

Exemplarily, if the serving cells currently operated by the terminal device are serving cells 1, 2, and 3, all of which are operated on BWP1, the terminal device determines that serving cell index 1, BWP index 1, and CG index 1 are activated according to the information indicated in PDCCH1. Alternatively, the terminal device determines that serving cell index 2, BWP index 1, and CG index 3 are activated according to the information indicated in PDCCH2. Alternatively, the terminal device determines that serving cell index 3, BWP index 1, and CG index 4 are activated according to the information indicated in PDCCH3.

S304. The terminal device sends first information to the network device. The first information is used to indicate whether the terminal device has received activation information or deactivation information of the first resource indicated by the downlink control information. The first information includes an identifier of the first resource.

S305: The network device determines the first resource according to the identifier of the first resource and the mapping relationship between the identifier of the first resource and the configuration information of the first resource.

The technical terms, technical effects, technical features, and optional implementation methods of S304-S305 can be understood with reference to S201-S202 shown in Figure 2, and repeated contents will not be repeated here.

In the communication method and apparatus provided by the embodiment of the present invention, a network device sends configuration information of at least one group of first resources to a terminal device, and a device in the terminal configures an identifier of the first resource according to the configuration information of at least one group of first resources, and the network device sends downlink control information to the terminal device to instruct the terminal device to activate or deactivate the first resource. In this way, the terminal device can configure the first resource identifier according to the instruction of the network device, and can activate or deactivate the first resource, so that after activating or deactivating the first resource, the terminal device can indicate the confirmation information of the first resource or the corresponding CG through the downlink control information.

Based on Figures 2-4, since the network device will configure up to 4 bandwidth parts BWP for the device in the terminal, only one of the four BWPs can be activated at the same time. If the terminal device works on one BWP, the terminal device receives the downlink control information of the activation or deactivation of the resources of the BWP, but has not yet reported the confirmation information to the network device, and the BWP is switched. At this time, the terminal device cannot determine which BWP resource status confirmation information to report. Figure 5 is a signaling interaction diagram of another communication method provided in an embodiment of the present application. As shown in Figure 5, the method includes:

S401. The network device sends downlink control information to the terminal device, where the downlink control information is used to indicate activation or deactivation of the corresponding CG, or to indicate activation or deactivation of the corresponding first resource.

S402. The network device sends a first indication to the terminal device, where the first indication is used to instruct the terminal device to change an uplink bandwidth portion.

S403: The terminal device changes the uplink bandwidth part according to the first instruction.

It should be noted that the embodiment of the present application does not limit how to change the uplink bandwidth part. For example, the BWP of Serving cell1 can be changed from BWP1 to BWP2.

S404. The terminal device reports the state of the first resource or whether the downlink control information of the first resource is received to the network device according to the first indication.

In this step, after changing the BWP, the terminal device confirms whether to report the first information, or how to report the first information. If the reporting of the first information is triggered but not reported or the first information is not successfully reported, the terminal device does not report the status of the first resource or whether the downlink control information of the first resource is received to the network device. This application does not limit how to report the first resource to the network device according to the change of the uplink BWP of the terminal device.

In some embodiments, if the terminal device sends or successfully sends the first information to the network device before the BWP is changed, then after the BWP is changed, the status of the first resource on the first BWP or whether the downlink control information of the first resource is received is not reported to the network device, and the first BWP is the BWP before the change.

In some embodiments, if the terminal device does not send or successfully send the first information to the network device before the BWP is changed, then after the BWP is changed, the state of the first resource on the first BWP or whether the downlink control information of the first resource is received is not reported to the network device, and the first BWP is the BWP before the change. If the first information sent by the terminal device to the network device before the BWP is changed is not sent or unsuccessfully sent due to the BWP change, then after the BWP is changed, the state of the first resource on the first BWP or whether the downlink control information of the first resource is received is reported to the network device, and the first BWP is the BWP before the change. If the uplink BWP changes multiple times, the state of the first resource on the second BWP or whether the downlink control information of the first resource is received is reported to the network device, and the second BWP is the BWP after the last change. Alternatively, if the uplink BWP changes multiple times, the state of the first resource on the third BWP or whether the downlink control information of the first resource is received is reported to the network device, and the third BWP is the BWP after the first change. Alternatively, if the uplink BWP is changed multiple times, the state of the first resource on the first BWP or whether the downlink control information of the first resource is received is reported, and the first BWP is the BWP before the BWP is changed.

In some embodiments, if the uplink BWP changes multiple times, whether the DCI for the first resource on the second BWP is received or the status of the first resource is reported to the network device, and the second BWP is the BWP after the last change and the first resource status change. Alternatively, if the uplink BWP changes multiple times, the first resource or the status of the first resource on the third BWP is reported to the network device, and the third BWP is the BWP after the first change and the first resource status change. Alternatively, if the uplink BWP changes multiple times, whether the DCI for the first resource on the first BWP is received or the status of the first resource is reported, and the first BWP is the bandwidth portion before the BWP is changed and the first resource status change.

For example, if the terminal device has not reported confirmation MAC CE on BWP2, but receives downlink control information indicating that the CG2 state on BWP2 has changed (here CG2 corresponds to a first resource). Before reporting confirmation MAC CE, the terminal device has another BWP change, such as from BWP2 to BWP3. Then, there is an available UL grant on BWP3. At this time, the terminal device can perform one of the following operations:

If the UL BWP is changed before the confirmation MAC CE is reported, the CG state before the BWP change or the reception state of the downlink control information corresponding to the CG (the CG here corresponds to a certain/certain first resources) will no longer be reported. That is, the confirmation MAC CE is not reported here.

If the UL BWP is changed before the confirmation MAC CE is reported, the CG status on the original BWP or the reception status of the DCI corresponding to the CG (the CG here corresponds to a certain/certain first resources) is reported for the first time after the BWP is changed. That is, if the BWP before the change is BWP1, the confirmation MAC CE reported here reports the CG status on BWP1.

If there are multiple BWP changes, the CG status corresponding to the most recently changed BWP or the reception status of the downlink control information corresponding to the CG is reported (the CG here corresponds to a certain/certain first resources). That is, the status of the CG on BWP2 is reported here.

If there are multiple BWP changes, the CG status corresponding to the first changed BWP or the reception status of the downlink control information corresponding to the CG is reported (the CG here corresponds to a certain/certain first resources). That is, the status of the CG on BWP2 is reported here.

If there are multiple BWP changes, the CG status corresponding to the original BWP before the BWP change, or the reception status of the downlink control information corresponding to the CG (the CG here corresponds to a certain/certain first resources) is reported. That is, the status of the CG on BWP1 is reported here.

In the communication method provided in the embodiment of the present application, a network device sends a first indication to a terminal device, and the first indication is used to instruct the terminal device to change the uplink BWP; after changing the BWP, confirm whether to report the first information, or how to report the first information. If the reporting of the first information is triggered but not reported or not successfully reported, the status of the first resource or whether the downlink control information of the first resource is received is reported to the network device. In this way, when the BWP of the terminal device is changed, both the terminal device and the network device can confirm the status of the first resource on the BWP corresponding to the reported information, thereby unifying the behavior of the terminal device and the network device and ensuring the consistency of the understanding of the reported information by the terminal device and the network device.
