Description

Communication method and communication device

Technical Field

The present application relates to the field of communications, and in particular, to a communication method and a communication apparatus.

Background

When the terminal is performing vehicle to other device communication (V2X) based on a Side Link (SL), data transmission can be performed using related resources configured by the network device. The resource configured by the network device may be a resource configured by a Configuration Grant (CG) method, or a resource configured by a Semi-Persistent Scheduling (SPS) method. The resource configured by the CG method may be referred to as a CG resource, and the resource configured by the SPS method may be referred to as an SPS resource.

The resources (such as the CG resources or the SPS resources described above) configured by the network device for the terminal may be divided into two types: resources that become active immediately after configuration and resources that need to be activated for use after configuration. Illustratively, the resource configured by the network device as the terminal is a CG resource. CG resources are divided into two categories according to different network device configuration modes: one is that the network device configures all parameters related to the CG resources through Radio Resource Control (RRC) signaling, and after completing the configuration of all parameters, the CG resources take effect immediately. The terminals can directly use the CG resources for communication. I.e., such CG resources are configured to take effect immediately after addition (add), as may be referred to as CG resources of the first type. Another type is that the network device configures a part of parameters related to the CG resource through RRC signaling, and after the configuration of the part of parameters is completed, the CG resource does not directly take effect, the network device needs to configure other parameters of the CG resource through a Physical Downlink Control Channel (PDCCH) by using Physical Downlink Control Information (DCI), and after the activation (active) of the CG resource is completed, the CG resource takes effect, and is used for communication of the terminal. That is, such CG resources need to be activated after being configured to be usable, and may be referred to as a CG resource of the second type.

The network device may process the resources configured for the terminal, in addition to configuring the resources for the terminal. For example, for the CG resource configured for the terminal, the network device may delete (release) the CG resource configured for the terminal through the reconfiguration message for the first CG resource. For the CG resources of the second type, the network device may deactivate (inactive) the CG resources configured for the terminal through the DCI. Similar to the CG resources processing performed by the network device, the network device may also perform corresponding processing on the SPS resources configured for the terminal by using the above two methods.

It is understood that the above management of terminal resources is all performed by the network device. However, in SL communication, data communication often occurs between terminals, and therefore, the network device does not know the use of the resources currently allocated to the terminals. This may have some undesirable consequences. For example, if resources already configured for the terminal are idle, the resources are wasted.

Disclosure of Invention

The embodiment of the application provides a communication method and device, which at least enable network equipment to efficiently perform corresponding processing on resources configured to a terminal so as to avoid waste of the resources.

In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

in a first aspect, the present application provides a communication method, in which a terminal sends first indication information to a network device through a physical uplink control channel, where the first indication information is used to indicate to process a first transmission resource, and the first transmission resource is a transmission resource configured for the terminal by the network device and used for performing side link SL communication. Illustratively, the processing may include deletion or deactivation.

By adopting the technical scheme, the terminal can send the first indication information to the network equipment through the physical uplink control channel of the physical layer so as to indicate the network equipment to delete or deactivate the configured first transmission resource, so that the network equipment can efficiently perform corresponding processing on the configured resource.

In one possible design, before the terminal sends the first indication information to the network device through the physical uplink control channel, the terminal may further receive first configuration information from the network device, where the first configuration information may include the first resource information and the second resource information. The first resource information is used for indicating a first transmission resource, the second resource information is used for configuring a physical uplink control channel, and the first transmission resource corresponds to the physical uplink control channel. Based on the method, the terminal can determine the transmission resource configured for the terminal by the network equipment, and can also determine the physical uplink control channel corresponding to the transmission resource.

In one possible design, the first indication information is an acknowledgement indication. Illustratively, the acknowledgement indication may be an ACK indication, which may be represented by 1 bit. Based on the method, the terminal can transmit the indication for processing the transmission resource to the network equipment through the existing information (such as ACK indication) without adding extra signaling overhead.

In one possible design, the first transmission resource is a configuration granted CG resource or a semi-persistent scheduled SPS resource. Based on the method, the terminal can instruct the network equipment to process the configured CG resource or SPS resource and other resources which can be used for V2X communication.

In one possible design, the sending, by the terminal, the first indication information to the network device through the physical uplink control channel includes: and the terminal sends the N pieces of first indication information to the network equipment through a physical uplink control channel. Or, the terminal sends the N pieces of first indication information to the network device through the physical uplink control channel within a preset time. Wherein N is an integer greater than 1. Based on the method, the terminal can ensure that the network equipment can accurately know the indication of the terminal for processing the first transmission resource through multiple times of sending the first indication information.

In a possible design, before the terminal sends the first indication information to the network device through the physical uplink control channel, the terminal receives second configuration information from the network device, where the second configuration information is used to indicate that the terminal does not send an acknowledgement indication when data transmitted in the SL communication does not need to be retransmitted. Based on the method, the terminal can determine, through the second configuration information, that the confirmation indication is not sent to the network device when the SL communication is successful, so that the terminal can use the confirmation indication to perform other information transfer, such as instructing the network device to process the first transmission resource.

Detailed Description

In order to clarify the technical solutions in the description of the embodiments, the terms related to the embodiments of the present application are explained below:

1) a terminal, also referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice/data connectivity to a user. For example, a handheld device having a wireless connection function, or a vehicle-mounted device, etc. Currently, some examples of terminals are: a vehicle-mounted computer, a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

2) Universal Mobile Telecommunications System (UMTS) is a 3G Mobile communications technology standard established by The 3rd Generation Partnership Project (3 GPP) organization. The Long Term Evolution (LTE) of the universal mobile telecommunications technology is a Long Term Evolution of the UMTS technology standard established by the 3GPP organization. Because of the evolution, we refer to the LTE Access Network portion as Evolved UMTS Terrestrial Radio Access Network (E-UTRAN). Correspondingly, the LTE Core network portion may be referred to as an Evolved Packet Core (EPC). In distinction to the 3G and 4G communication technology standards, the 5G access network part is referred to as NG-RAN and the 5G core network part is referred to as 5 GC.

3) Mobility Management Entity (MME) is a key control node of a 3GPP protocol LTE access network, and is responsible for positioning idle mode ue (user equipment) and paging process, including relaying. In short, the MME is responsible for the signaling processing. The Serving GateWay (S-GW) is a GateWay that terminates at the E-UTRAN interface, and the main functions of the S-GW may include, for example: when switching between eNBs, the eNB can be used as a local anchor point and assist in completing the reordering function of the eNBs; when switching among different access networks of 3GPP, the method is used as a mobility anchor point and also has a reordering function; performing a lawful interception function; routing and forwarding the data packet; grouping and marking are carried out on an uplink transmission layer and a downlink transmission layer; in idle state, the downlink packet buffer and the service request function triggered by the initiation network; for inter-operator charging, etc.

4) A network device is a device in a wireless network, such as a Radio Access Network (RAN) node that accesses a terminal to the wireless network. Currently, some examples of RAN nodes are: a gbb, ng-eNB, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved NodeB or home Node B, HNB), a Base Band Unit (BBU), a Roadside Unit (RSU), or a wireless fidelity (Wifi) Access Point (AP), etc.

5) Vehicle and other equipment communication: i.e., V2X communication, may be applied in a transportation network. V2X communication may include Vehicle to Vehicle (V2V) communication, Vehicle to roadside Infrastructure (V2I) communication, and Vehicle to pedestrian (V2P) communication. Among them, V2V communication may be performed on a sidelink (sidelink), and V2I communication may be performed on a Downlink (DL).

6) And SL communication: sidelink-based communications. SL communication may transmit data on a Physical SL Control Channel (PSCCH) and/or a physical SL shared Channel (PSCCH). For example, the SL communication may be a V2X communication that occurs from terminal to terminal. For example, the network device may allocate resources for the terminal to perform SL communication, such as CG resources, and also such as SPS resources, and the terminal may perform SL communication, such as data transmission, with other terminals on the allocated CG resources and/or SPS resources.

7) And Uu port communication: and communication between the terminal and the network equipment based on the Uu port.

The following describes in detail specific embodiments of examples of the present application.

Before the terminal performs communication, the network device is required to configure corresponding resources for the terminal. The terminal communicates on the resources configured by the network equipment. The network device may configure the resources by using a Dynamic Scheduling (DS) method. In the present embodiment, the resources configured by the method of DS may be referred to as DS resources. The network device may also configure the above resources using the SPS method. In the present embodiment, the resources configured by the SPS method may be referred to as SPS resources.

For example, the DS resource may be a resource configured by a Network device for a terminal in a Transmission Time Interval (TTI) using a Physical Downlink Control Channel (PDCCH) scrambled by a Cell-Radio Network Temporary Identifier (C-RNTI). The DS resource has the characteristics of one-time allocation and one-time use. That is, the network device needs to allocate DS resources to the terminal once per communication. In contrast, SPS resources are characterized by one-time allocation and multiple-time use. That is, the SPS resources allocated by the network device to the terminal may be used for the terminal to perform multiple communications repeatedly. The SPS resource has a characteristic of low PDCCH overhead compared with the DS resource, so the SPS resource is more suitable for periodic packet services, such as Voice Over Internet Protocol (VOIP) services and the like.

Currently, when a terminal performs SL-based V2X communication, in addition to using the SPS resources, a resource configured for the terminal in a New Radio (NR) by a network device, such as a resource configured by a CG method, may also be used. In the present embodiment, the resources configured by the CG method may be referred to as CG resources. Illustratively, as shown in fig. 1, when a terminal 1 needs to perform SL communication with a terminal 2, a network device may configure CG/SPS resources for the terminal 1 for SL communication. On which terminal 1 can communicate SL with terminal 2. Since the CG/SPS resource configuration is completed by the network device, in some communication (such as the SL communication shown in fig. 1), the network device cannot know the usage of the resource configured for the terminal, and cannot reasonably process the resource configured for the terminal (such as deleting or deactivating the idle CG/SPS resource), which inevitably results in resource waste.

In order to solve the above problem, in the prior art, a terminal may report traffic pattern (traffic pattern) information to a network device through a terminal assistance message (UAI), so that the network device may manage resources of the terminal according to the traffic pattern information. For example, the network device may determine whether to manage CG/SPS resources for a certain period according to a traffic period (traffic periodicity) in the traffic pattern information. For example, the service cycle fed back to the network device by the terminal includes (sf20, sf50, sf100, sf200), then the network device may configure the CG/SPS resource with cycle of 20,50,100,200 for the terminal. Thereafter, if the service period fed back to the network device by the terminal includes (sf50, sf100, sf200), the network device may modify the resource configured for the terminal to be a CG/SPS resource with a period of 50,100,200, that is, the network device may delete or deactivate the CG/SPS resource with a period of 20 configured for the terminal.

However, the method for deactivating or deleting resources through the UAI still has some problems:

1) and in the SL communication scenario, there may not be uplink resources of the Uu port between the terminal and the network device. If the terminal needs to report the service mode information to the network device through the UAI, the terminal needs to apply for the uplink resource of the Uu port to the network device before sending the service mode information, which undoubtedly generates additional signaling overhead.

2) UAI is a kind of RRC signaling, which is located above a physical layer and a Media Access Control (MAC) layer on a network architecture, and it takes a longer time to be received by a receiving network device compared to MAC signaling and physical layer signaling.

3) When the network equipment configures two or more CG/SPS resources with the same period for the terminal, the network equipment cannot identify the CG/SPS resources needing to be deleted or deactivated through UAI signaling. For example, the network device configures CG resources with respective periods of 20,50,20, and 100 for the terminal, and thereafter, if the network device receives the traffic pattern information including (sf20, sf50, sf100) sent by the terminal, the network device cannot distinguish which CG resource with a period of 20 needs to be deleted or deactivated, and thus cannot perform correct resource management.

At present, besides the network device can perform corresponding processing on CG/SPS resources configured for the terminal according to the UAI sent by the terminal, the network device can also use the MAC CE as a reference for processing the CG/SPS resources. However, although the MAC CE belongs to MAC signaling, the transceiving speed of the MAC CE is faster than that of RRC signaling (such as UAI), but the MAC CE still has a slower signaling speed than that of the physical layer, and the above other problems also exist.

The embodiment of the application provides a communication method, which can enable network equipment to efficiently perform corresponding processing on CG/SPS resources configured for a terminal, such as deleting or deactivating the CG/SPS resources configured for the terminal, so as to avoid waste of resources.

The communication method provided by the present application is described in detail below with reference to the accompanying drawings.

Please refer to fig. 2, which is a schematic diagram of a network architecture according to an embodiment of the present application. Taking an LTE network as an example, the network architecture may include E-UTRAN and EPC, as an example. The E-UTRAN may consist of one or more enbs, while the EPC may include one or more S-GWs and MMEs. The enbs may be connected to each other through an X2 interface. The eNB in E-UTRAN may be connected to the MME or S-GW through the S1 interface. For example, an eNB in E-UTRAN may be connected to an MME through an S1-MME interface, and an eNB in E-UTRAN may be connected to an S-GW through an S1-U interface, as another example.

Please refer to fig. 3, which is a schematic diagram of another network architecture according to an embodiment of the present application. Taking a 5G network as an example, the network architecture may include a NG-RAN composed of one or more gnbs and/or one or more NG-enbs, and a 5GC composed of one or more Access and Mobility Management Function (AMF) and/or one or more User Plane Function (UPF). The gNB and the NG-NB can be connected with each other through an Xn interface, and both the gNB and the NG-NB can be connected to the 5GC through an NG interface.

Under the network architecture shown in fig. 2 or fig. 3, for V2X communication, an eNB or a device under the gbb (i.e., a terminal capable of communicating with the eNB shown in fig. 2 and with the gbb and/or ng-eNB shown in fig. 3) may be referred to as a terminal in V2X communication. For example, in the V2X communication scenario shown in fig. 4, device 1, device 2, and device 3 may be referred to as terminals in this scenario. The terminal described in this embodiment may be a terminal in the V2X communication described above.

The communication method provided by the embodiment of the application can be applied to V2X communication. The network for supporting V2X communication may be any mobile communication network, such as the network shown in fig. 2 or fig. 3. In addition, the technical solution of the present embodiment can be applied to any scenario of V2X communication, such as the scenario shown in fig. 1 or fig. 4. For example, when the scenario shown in fig. 1 occurs under the network architecture shown in fig. 2, that is, the network device in fig. 1 is the eNB in fig. 2, the eNB may configure the terminal 1 with resources (e.g., CG/SPS resources) for V2X communication, and the terminal 1 may perform SL communication with the terminal 2 according to the CG/SPS resources configured by the eNB. For another example, when the scenario shown in fig. 4 occurs under the network architecture shown in fig. 3, that is, the network device in fig. 4 is a gNB or an ng-eNB in fig. 3, the gNB and/or the ng-eNB may configure resources (e.g., CG/SPS resources) for performing V2X communication for the device 1 and the device 2, and then the device 1 may implement SL communication with the device 3 on the configured CG/SPS resources, and similarly, the device 2 may also implement SL communication with the device 1 on the configured CG/SPS resources. It is understood that the scenario shown in fig. 1 may also occur under the network architecture shown in fig. 3 and enable SL communication between terminals, while the scenario shown in fig. 4 may also occur under the network architecture shown in fig. 2 and enable SL communication between devices. Needless to say, the V2X communication (for example, SL communication) scenario according to the embodiment of the present invention is not limited to the scenario shown in fig. 1 or the scenario shown in fig. 4, and may be another scenario in which V2X communication is possible. The scenario shown in fig. 1 and the scenario shown in fig. 4 are only used as examples for explanation, and are not limited at all.

In the communication method provided by the embodiment of the present application, the terminal may instruct the network device to process the transmission resource, such as a CG resource or an SPS resource, on the physical layer resource configured for the terminal by the network device. Upon receiving the indication, the network device may process transmission resources corresponding to the physical layer resources. Wherein, the processing of the transmission resource by the network device may be deactivation or deletion. Therefore, the network equipment can efficiently manage the transmission resources, and the resource waste is effectively avoided. In the following example, a transmission resource is taken as a CG resource for a more clear description of the embodiments of the present application.

Please refer to fig. 5, which is a flowchart illustrating a communication method according to an embodiment of the present application. The method may include S501-S504.

S501, the network device sends first configuration information to the terminal, wherein the first configuration information comprises first resource information and second resource information, the first resource information is used for indicating first transmission resources, the second resource information is used for configuring a physical uplink control channel, and the first transmission resources correspond to the physical uplink control channel.

The first transmission resource is a transmission resource which is allocated to the terminal by the network device and is used for SL communication.

Illustratively, to support V2X communication (such as SL communication) of a terminal, a network device may configure 1 or more CG resources for the terminal and transmit first resource information indicating the CG resources to the terminal through configuration information. In the embodiment of the present application, the first transmission resource may be any one of these CG resources.

For example, the network device needs to configure CG resources including CG 1, CG 2, and CG3 for the terminal. The network device may transmit configuration information 1 including resource information 1 to the terminal, the resource information 1 indicating CG 1. The network device may also transmit configuration information 2 including resource information 2 to the terminal, the resource information 2 indicating CG 2. The network device may also transmit configuration information 3 including resource information 3 to the terminal, the resource information 3 indicating CG 3.

The network device may also configure a Physical Uplink Control Channel (PUCCH) corresponding to the CG resource for the terminal, that is, the network device may configure a corresponding PUCCH for each CG resource, and send second resource information indicating the PUCCHs to the terminal.

For example, continuing with the above example, the network device may configure the terminal with PUCCH 1 corresponding to CG 1, PUCCH 2 corresponding to CG 2, and PUCCH3 corresponding to CG 3. The network device may transmit resource information a for configuring PUCCH 1 to the terminal. The network device may also send resource information B to the terminal, which is used to configure PUCCH 2. The network device may also send resource information C to the terminal, which is used to configure PUCCH 3.

The network device may issue the second resource information for configuring the PUCCH and the corresponding first resource information for indicating the CG resource to the terminal. For example, continuing with the above example, the network device may carry the resource information 1 and the resource information a in the configuration information 1, and issue the resource information a and the resource information a to the terminal. And carrying the resource information 2 and the resource information B in the configuration information 2 and issuing the resource information B to the terminal. And carrying the resource information 3 and the resource information C in the configuration information 3 and issuing the resource information C to the terminal.

The network device may transmit the configuration information 1, the configuration information 2, and the configuration information 3 to the terminal, respectively, or may transmit the configuration information to the terminal together. In addition, the network device may simultaneously configure different CG resources and PUCCHs corresponding to the CG resources, or may configure the CG resources and the PUCCHs at different times.

S502, the terminal receives first configuration information from the network equipment.

The terminal can know the CG resource allocated to the terminal by the network device and the PUCCH corresponding to the CG resource according to the received first configuration information.

Illustratively, continuing with the example in S501 above, the terminal may know that the network device has allocated CG 1 for SL communication according to resource information 1 included in configuration information 1. The terminal may also know PUCCH 1 corresponding to CG 1 according to resource information a included in configuration information 1. Similarly, the terminal may know that the network device allocates CG 2 for SL communication and PUCCH 2 corresponding to CG 2 according to configuration information 2, and the terminal may know that the network device allocates CG3 for SL communication and PUCCH3 corresponding to CG3 according to configuration information 3.

S503, the terminal sends first indication information to the network device through the physical uplink control channel, where the first indication information is used to indicate to process the first transmission resource.

Wherein the first indication information may be an acknowledgement indication. The acknowledgement indication may be an ACK indication or other indication information having an acknowledgement function. Illustratively, the ACK indication may be represented by 1 bit, e.g., the ACK indication may be "1".

In the embodiment of the present application, the terminal is always a participant of communication (such as SL communication), and therefore, the terminal can know the use condition of the resource configured for the current communication by the network device. When determining that the network device needs to process the configured resource according to the use condition, the terminal may send first indication information to the network device, where the first indication information is used to indicate the network device to process the configured resource (such as the first transmission resource).

As described in the foregoing embodiment, the resources configured by the network device for the terminal may be divided into the first type of resources and the second type of resources. The first kind of resources are resources which take effect immediately after being configured, and the second kind of resources are resources which need to be activated to take effect after being configured. The processing methods for different kinds of resources are different. For example, the processing of the resource may be deletion or deactivation.

For example, the network device configures CG 1, CG 2, and CG3 for the terminal. Take the example that the first transmission resource is CG 1 and CG 1 is the second type resource. If the terminal determines that the CG 1 is not required to be used and the CG 1 is already activated, the terminal may transmit first indication information including an ACK indication to the network device through the PUCCH 1 corresponding to the CG 1. The first indication information is used to indicate that CG 1 is deactivated.

For another example, the network device configures CG 1, CG 2, and CG3 for the terminal. Take the first transmission resource CG 2 and CG 1 as the first type resource as an example. If the terminal determines that CG 2 is not required to be used, the terminal may transmit first indication information including an ACK indication to the network device through PUCCH 2 corresponding to CG 2, for indicating deletion of CG 2.

It can be understood that, for the information sent by the terminal to the network device, the network device generally needs to perform parsing to perform the corresponding operation. In the parsing process, there may be some cases of incorrect parsing. For example, the information sent by the terminal to the network device is the first indication information. The first indication information sent by the terminal to the network device is an ACK indication, for example, the content of the ACK indication is "1" with 1 bit. When the network device analyzes the information, the network device may erroneously analyze the information as "0". Although the probability of occurrence of such an erroneous analysis is low, the erroneous determination of the terminal transmission instruction by the network device is also affected to some extent. Therefore, in some embodiments, when determining that a CG resource configured for the network device needs to be processed, the terminal may send N pieces of first indication information for processing the CG resource to the network device on a PUCCH corresponding to the CG resource, so that the network device may explicitly know that the CG resource needs to be processed. Wherein N is an integer greater than 1. In other embodiments, the terminal may send the N pieces of first indication information to the network device on the PUCCH corresponding to the CG resource within a preset time. For example, a timer may be preset in the terminal, when the terminal determines that the network device needs to process the CG resource configured for the terminal, the timer is triggered to start timing, and the terminal may send N pieces of first indication information to the network device on the PUCCH corresponding to the CG resource before the timing of the timer is ended.

It should be noted that there are cases where the ACK indication is used in some scenarios of V2X communication. For example, after the CG resource configured by the network device is received by the terminal, the terminal may perform SL communication with another terminal on the CG resource, and for example, the terminal (e.g., terminal 1) may transmit data to another terminal (e.g., terminal 2) on the CG resource. If terminal 2 determines that the data was successfully received, an ACK indication may be sent to terminal 1 indicating that terminal 1 has successfully received the data. After that, the terminal 1 may send an ACK indication to the base station for informing the network device that the SL communication on the current CG resource has been successful. It will be appreciated that since the current SL communication has been successful, the network device does not need to respond to the ACK indication after receiving the ACK sent by terminal 1. Therefore, in this method, the ACK indication sent by the terminal 1 to the network device is unnecessary, and the signaling overhead between the network device and the terminal is increased.

In this embodiment of the present application, the network device may send, to the terminal, an ACK instruction for instructing the terminal not to send to the network device in the above scenario (that is, when data transmitted in SL communication does not need to be retransmitted). The terminal may receive the second configuration information from the network device. For example, when it is determined that the SL communication is successful, that is, data retransmission is not required, the terminal may not send an ACK indication to the network device according to the second configuration information. In this way, the terminal may use the ACK indication to transmit other information to the network device, for example, indicate the network device to delete or deactivate the first transmission resource through the ACK indication.

S504, the network device receives the first indication information from the terminal through the physical uplink control channel, and processes the first transmission resource.

After receiving the first indication information from the terminal through the PUCCH, the network device may perform corresponding processing on the first transmission resource corresponding to the PUCCH.

For example, in connection with the example in S503, the first indication information may be a 1-bit ACK indication, the first transmission resource is CG 1, and CG 1 is the second type of resource. When the network device receives the ACK indication from the terminal through PUCCH 1, the network device may determine to deactivate a CG resource, that is, CG 1, corresponding to PUCCH 1 according to a physical layer resource, that is, PUCCH 1, receiving the ACK indication. For another example, in combination with the example in S503, the first indication information is an ACK indication with 1 bit, the first transmission resource is CG 2, and CG 2 is the first type resource. When the network device receives the ACK indication from the terminal through the PUCCH 2, the network device may determine to delete the CG resource, that is, the CG 2, corresponding to the PUCCU 2 according to the physical layer resource, that is, the PUCCH 2, which receives the ACK indication.

Under the scene that the terminal sends N pieces of first indication information to the network equipment. In some embodiments, the processing, by the network device, the first transmission resource may specifically be: the network device processes the first transmission resource after receiving the plurality of first indication information from the terminal. Illustratively, a counter (counter) N may be defined in the network device, where N is an integer greater than 1. When the network device receives a first ACK indication from the terminal, the counter is set to 1, and then the network device adds 1 to the value of the counter every time the network device receives an ACK indication until the value of the counter is equal to N, the network device determines to process the CG resource corresponding to the PUCCH receiving the ACK indication, and then the network device may process the CG resource.

In other embodiments, the processing, by the network device, the first transmission resource may specifically be: the network device may determine that the first transmission resource is processed when the counter reaches N within the preset time. Illustratively, a timer (timer) may be set in the network device. When the network device receives a first ACK indication from the terminal, the timer starts timing, the counter is set to be 1, the value of the counter is added with 1 when the network device receives an ACK indication, and when the network device determines that the value of the counter reaches N before the timer is overtime, the network device determines that the CG resource corresponding to the PUCCH receiving the ACK indication needs to be processed, and then the network device can process the CG resource.

It is understood that the resources configured by the network device for the terminal, such as CG resources, have a certain period. During this period, the CG resources can support the terminal for communication (e.g., SL communication). In this embodiment, the network device may implement accurate reception of the indication information (e.g., the first indication information) by monitoring the PUCCH corresponding to the CG resource. However, if the network device monitors all the PUCCHs corresponding to the CG resources that have been allocated at any time after the CG resources are allocated, a large burden is imposed on the network device.

Therefore, in some embodiments of the present application, a timer may be set in the network device, and is used to schedule a time for the network device to monitor each PUCCH, so as to improve the working efficiency of the network device. For example, a network device allocates CG 1, CG 2, and CG3 to a terminal, and allocates PUCCH 1, PUCCH 2, and PUCCH3 to these CG resources, respectively. The network device can start a timer at any time in the period in which the CG 1 is effective, and start monitoring the PUCCH 1. If the network device receives an ACK indication on PUCCH 1 before the timer times out, the network device may delete or deactivate CG 1. Similarly, the network device may start the timer to start monitoring the PUCCH 2 at any time within the period in which the CG 2 is active. If the network device receives an ACK indication on PUCCH 2 before the timer times out, the network device may delete or deactivate CG 2. The network device may start a timer at any time within the period in which the CG3 is active, and start monitoring the PUCCH 3. If the network device receives an ACK indication on PUCCH3 before the timer times out, the network device may delete or deactivate CG 3. And after the timer is overtime, the network equipment stops monitoring the corresponding PUCCH so as to achieve the purpose of reducing the burden of the network equipment.

In addition, the communication method provided by the embodiment of the present application may also be used in a process of configuring (e.g., activating or adding) resources, such as CG resources, for a terminal. For example, the terminal may send indication information to the network device on the PUCCH, for indicating the network device to activate or add a CG resource. The network device may perform the activation or addition of the CG resource according to the indication information.

For example, the network device allocates CG 1, CG 2 and CG3 to the terminal (e.g. UE 1), and allocates PUCCH 1, PUCCH 2 and PUCCH3 to these CG resources correspondingly. UE1 may perform data transmission with other terminals (e.g., UE 2) on these CG resources. When the UE 2 does not successfully receive the data transmitted by the UE1 at the CG3, a Hybrid Automatic Repeat Request (HARQ) may be returned to the UE1, for instructing the UE1 to retransmit the data transmitted at the CG 3. The UE1 may send a Negative (NACK) indication to the network device on PUCCH3 corresponding to the CG3 source for instructing the network device to allocate retransmission resources. The network device may configure retransmission resources for the terminal upon receiving the NACK indication. The network device may configure the retransmission resource for the terminal by adding a new CG resource of the first type to the terminal, or may configure the CG resource of the second type that is already configured for the terminal but is not activated. In addition, the retransmission resource may also be configured for the terminal by the network device through a Dynamic Grant (Dynamic Grant) method. The embodiments of the present application are not limited thereto.

It should be noted that, in the above embodiments, the resource configured by the network device as the terminal is taken as the CG resource as an example, and the communication method provided in the embodiment of the present application may also be applied in a scenario where the resource configured by the network device as the terminal is a Uu port uplink SPS resource, or a Uu port downlink SPS resource, or an SPS resource on the SL. The specific implementation is the same as the steps shown in fig. 5, and will not be described herein again.

According to the communication method provided by the embodiment of the application, the terminal indicates the network equipment to process the CG/SPS resources on the PUCCH which is configured by the network equipment and corresponds to the CG/SPS resources. Since the method of the present application transmits the indication information through the PUCCH, the transmission speed is significantly higher than that of RRC signaling or MAC signaling. In addition, since the PUCCH corresponds to CG/SPS resources configured for the terminal, if the terminal needs to instruct the network device to process a part of resources of two or more resources having the same period, the network device may accurately determine the resources required to be processed according to the PUCCH receiving the instruction information by transmitting the instruction information on the PUCCH corresponding to the resources required to be processed. Meanwhile, in the method, the 1-bit ACK indication is used as the deactivation/deletion indication information, and the data volume of the information is very small, so that no extra burden is caused on the communication between the terminal and the network equipment. And when the communication quality between the terminal and the network equipment can not be ensured, the network equipment can also easily acquire the indication information. Therefore, the communication method provided by the embodiment of the application can achieve the purposes that the network equipment can efficiently process CG/SPS resources and avoid resource waste.
