Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to wireless communication methods, terminal devices, and network devices. Background Technology

[0002] In the New Radio Unlicensed (NRU or NR-U) spectrum scenario, to better serve periodic services, the concept of pre-configured resources has been introduced, such as Semi-Persistent Scheduling (SPS) and Configured Grant (CG) resources. The maximum number of Hybrid Automatic Repeat Request (HARQ) processes supported by the terminal is 16. For each CG resource, the network device can configure a limited number of HARQ process numbers and introduces a per-HARQ process configured grant timer mechanism. Before the configured grant timer expires, the Media Access Control Protocol Data Units (MACPDUs) stored in the HARQ process cannot be flushed.

[0003] In addition, a configuration grant retransmission timer (cg-RetransmissionTimer) is introduced for each HARQ process to trigger automatic retransmission on CG resources. Specifically, if no acknowledgment (ACK) is received before the cg-RetransmissionTimer expires and the configuredGrantTimer expires, automatic retransmission is triggered.

[0004] In some scenarios, if cg-RetransmissionTimer is configured but configuredGrantTimer is not, the behavior of the terminal device is undefined. Summary of the Invention

[0008] Thirdly, a wireless communication method is provided, the method comprising: a network device generating configuration information of a first configured authorized CG resource according to a first constraint condition, wherein the configuration information of the first CG resource includes information of a CG timer corresponding to the first CG resource and information of a CG retransmission timer corresponding to the first CG resource, wherein the first constraint condition is used to indicate that the CG timer corresponding to the first CG resource also needs to be configured when configuring the CG retransmission timer corresponding to the first CG resource; and the network device sending the configuration information of the first CG resource to a terminal device.

[0009] Fourthly, a terminal device is provided, including a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to perform the methods described in the first or second aspect above.

[0013] Eighthly, a computer program product is provided, including computer program instructions that cause a computer to perform the methods of any one of the first to fourth aspects or their respective implementations.

[0014] Ninthly, a computer program is provided that, when run on a computer, causes the computer to perform the methods of any one of the first to third aspects or their respective implementations.

[0015] Based on the above technical solution, when the network device only configures the CG retransmission timer corresponding to the CG resource and does not configure the CG timer of the CG resource, the terminal device can use the CG resource to retransmit or retransmit data, thus clarifying the behavior of the terminal device and ensuring data transmission in this scenario.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art without creative effort regarding the embodiments of this application are within the scope of protection of this application.

[0026] The embodiments of this application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution system of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems, etc.

[0027] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC) communication, and vehicle-to-vehicle (V2V) communication. The embodiments of this application can also be applied to these communication systems.

[0028] Optionally, the communication system in this application embodiment can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) network deployment scenario.

[0029] The embodiments of this application do not limit the spectrum to be applied. For example, the embodiments of this application can be applied to licensed spectrum, unlicensed spectrum, or shared spectrum.

[0030] For example, the communication system 100 used in the embodiments of this application is as follows: Figure 1 As shown. The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

This application embodiment does not limit this.

[0032] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment.

[0033] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Figure 1Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities and other network entities. This application embodiment does not limit this.

[0034] It should be understood that the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Furthermore, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0035] It should be understood that the term "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a relationship. For example, A instructing B can mean that A directly instructs B, such as B being able to obtain information through A; it can also mean that A indirectly instructs B, such as A instructing C, so B can obtain information through C; or it can mean that there is a relationship between A and B.

[0036] In the description of the embodiments of this application, the term "correspondence" may indicate that there is a direct or indirect correspondence between two things, or that there is an association between two things, or that there is a relationship of instruction and being instructed, configuration and being configured, etc.

[0037] Optionally, the configuration parameters, configuration information, or configuration signaling in the embodiments of this application include at least one of Radio Resource Control (RRC) signaling and Media Access Control (MAC CE).

[0038] This application describes various embodiments in conjunction with terminal devices and network devices, wherein: the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (ST) in a WLAN, a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, and next-generation communication system, such as terminal device in an NR network or terminal device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0039] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0040] Network devices can be devices used to communicate with mobile devices. Network devices can be access points (APs) in WLANs, base stations (BTSs) in GSM or CDMA, base stations (NodeBs, NBs) in WCDMA, evolved base stations (eNBs or eNodeBs) in LTE, relay stations or access points, or in-vehicle devices, wearable devices, and network devices or base stations (gNBs) in NR networks, or network devices in future evolved PLMN networks, etc.

[0041] In this embodiment, the network device may have mobility characteristics; for example, the network device may be a mobile device. Optionally, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station located on land, water, or other similar locations.

[0042] In this embodiment, the network device provides services to the cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be the cell corresponding to the network device (e.g., base station). The cell can belong to a macro base station or to a base station corresponding to a small cell. The small cell can include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-speed data transmission services.

[0043] In this application embodiment, "predefined" can be implemented by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices). This application does not limit the specific implementation method. For example, predefined can refer to what is defined in the protocol.

[0044] In this application embodiment, the "protocol" may refer to a standard protocol in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems. This application does not limit this.

[0045] Unlicensed spectrum (also known as shared spectrum or unlicensed spectrum) is spectrum allocated by a country or region for use in wireless communication. This spectrum is usually considered to be shared spectrum, meaning that communication equipment in different communication systems can use the spectrum as long as it meets the regulatory requirements set by the country or region on that spectrum, without needing to apply for a proprietary spectrum license from the government.

[0046] To ensure the amicable coexistence of various communication systems using unlicensed spectrum, some countries and regions have stipulated regulatory requirements for the use of unlicensed spectrum. For example, communication devices must adhere to the "Listen Before Talk (LBT)" principle. This means that before transmitting signals on an unlicensed spectrum channel, the device must first listen for channel availability. Transmission is only permitted if the channel is idle; otherwise, it cannot transmit. To ensure fairness, the duration of signal transmission using an unlicensed spectrum channel in a single transmission cannot exceed the Maximum Channel Occupancy Time (MCOT).

[0047] For example, to avoid subband interference to signals transmitted on unlicensed spectrum channels and to improve the detection accuracy of communication equipment when detecting unlicensed spectrum channels, signals transmitted on unlicensed spectrum channels need to occupy at least a certain percentage of the channel bandwidth. For example, in the 5GHz band, the signal occupies 80% of the channel bandwidth, and in the 60GHz band, it occupies 70% of the channel bandwidth. Taking 20MHz as an example, to meet the requirement of the signal occupying 80% of the channel bandwidth, the bandwidth occupied by the signal should be at least 16MHz.

[0048] For example, to prevent signals transmitted on unlicensed spectrum channels from having too much power and affecting the transmission of other important signals on that channel, such as radar signals, regulations stipulate the maximum power and maximum power spectral density when communication equipment uses unlicensed spectrum channels for signal transmission.

[0049] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0050] To facilitate a better understanding of the embodiments of this application, the background of the CG timer mechanism and NRU will be explained first.

[0051] NRU related background:

[0052] NRU includes the following working scenarios:

[0053] Scenario A: Carrier aggregation scenario, the primary cell (PCell) corresponds to the licensed spectrum, and the secondary cell (SCell) corresponds to the unlicensed spectrum.

[0054] Scenario B: Dual connectivity working scenario, PCell corresponds to LTE licensed spectrum, and primary secondary cell (PScell) corresponds to unlicensed spectrum.

[0055] Scenario C: Standalone operating scenario, where a standalone cell operates on unlicensed spectrum.

[0056] Scenario D: NR single-cell scenario, the uplink (UL) operates on the licensed spectrum, and the downlink (DL) operates on the unlicensed spectrum;

[0057] In NRU scenarios, to better serve periodic services, the concept of pre-configured resources is introduced, such as Semi-Persistent Scheduling (SPS) and Configured Grant (CG) resources. The maximum number of Hybrid Automatic Repeat Request (HARQ) processes supported by the terminal is 16. For each CG resource, the network configures a limited number of HARQ process numbers, and the HARQ process number of the CG resource at time t0 is the same as that at time t1. For example, when the Media Access Control (MAC) packet generates MAC Protocol Data Unit (PDU) 1 at time t0, MAC PDU 1 is stored in HARQ process A. At time t1, because the HARQ processes are the same, MAC PDU 1 will be overwritten (flushed), even if the MAC PDU has not yet been correctly transmitted. Therefore, a configured grant timer mechanism per HARQ process is introduced. Before the configuredGrantTimer expires, the MACPDU stored in the HARQ process cannot be flushed. After the configuredGrantTimer expires, the terminal device determines that the network device will not retransmit, and can then use the resources corresponding to the HARQ process for data transmission.

[0058] The configuredGrant Timer is maintained by each HARQ process. This means that the configuredGrant Timer only restricts the use of CG resources by its corresponding HARQ process, but does not restrict the use of CG resources by other HARQ processes.

[0059] A configuration-authorized retransmission timer (cg-RetransmissionTimer) is introduced to trigger automatic retransmission on CG resources. Specifically, if no acknowledgment (ACK) is received before the cg-RetransmissionTimer expires and the configuredGrantTimer expires, automatic retransmission is triggered.

[0060] In some scenarios, if cg-RetransmissionTimer is configured but configuredGrantTimer is not, the behavior of the terminal device is undefined.

[0061] Figure 2 This is a schematic flowchart of a wireless communication method 200 according to an embodiment of this application, such as... Figure 2 As shown, the method 200 may include at least some of the following:

[0062] S210, the terminal device receives configuration information of the first configuration authorized CG resource sent by the network device. The configuration information of the first CG resource includes the information of the CG retransmission timer corresponding to the first CG resource, but does not include the information of the CG timer corresponding to the first CG resource. The first CG resource corresponds to the first hybrid automatic request retransmission (HARQ) process.

[0063] S220, when the first CG resource is configured with a CG retransmission timer but not with a CG timer, the terminal device uses the first CG resource to perform new transmission or retransmission of data.

[0064] Optionally, in some embodiments, the first CG resource is a resource on unlicensed spectrum. That is, the embodiments of this application can be applied to scenarios where data transmission is performed using resources on unlicensed spectrum, such as the NRU scenarios described above.

[0065] Optionally, in some embodiments, the configuration information of the first CG resource may further include information about the first CG resource, such as its starting position, size, and period. That is, the network device can configure the CG retransmission timer corresponding to the CG resource when configuring the CG resource.

[0066] Optionally, the configuration information of the first CG resource can be configured via Radio Resource Control (RRC) signaling. For example, the configuration information of the first CG resource can be carried in the CG configuration (ConfiguredGrantConfig) information element (IE) in the RRC signaling.

[0067] It should be understood that the CG timer and CG retransmission timer in the embodiments of this application correspond to the first HARQ process. In other words, the CG timer and CG retransmission timer are used to limit the use of CG resources by the corresponding first HARQ process.

[0068] In cases where the network device has only configured a corresponding CG retransmission timer for the first CG resource, but has not configured a corresponding CG timer, the terminal device uses the first CG resource for new transmission or retransmission of data. Alternatively, in some other embodiments, the terminal device may not use the first CG resource for data transmission.

[0069] The following describes the specific implementation method on the terminal device side, with reference to specific embodiments.

[0070] Example 1: The terminal device uses the first CG resource to retransmit data.

[0071] Example 1: Regardless of whether the current state of the first HARQ process is pending or not pending, the terminal device uses the first CG resource for data retransmission.

[0072] Optionally, in this embodiment 1, the first CG resource can be a resource that meets specific conditions, such as the first CG resource not conflicting with the first PUSCH resource, wherein the first PUSCH resource has a higher priority than the first CG resource, or the first PUSCH resource is a specific resource.

[0073] In other words, if the first CG resource meets certain conditions, the terminal device can use the first CG resource to retransmit data, regardless of whether the first HARQ process is suspended.

[0074] Optionally, the non-conflict between the first CG resource and the first PUSCH resource may mean that the first CG resource and the first PUSCH resource do not overlap or partially overlap in the time domain.

[0075] In some embodiments, the first CG resource is not configured with a logical channel-based priority selection rule, and the first PUSCH resource includes at least one of the following:

[0076] Physical uplink shared channel (PUSCH) resources scheduled by downlink control information (DCI);

[0077] The PUSCH resources scheduled by Random Access Response (RAR), or in other words, the PUSCH resources of the Physical Downlink Control Channel (PDCCH) scrambled with Random Access Radio Network Temporary Identifier (RA-RNTI).

[0078] PUSCH resources for PDCCH scheduling scrambled by Temporary Cell Radio Network Temporary Identity (TC-RNTI);

[0079] The PUSCH resource carries message A in a contention-based two-step random access process, wherein message A includes a random access preamble and identification information of the terminal device.

[0080] Message A, also known as MSGA, may include Msg1 and Msg3 in a contention-based four-step random access process. Msg1 is also called the random access preamble, preamble sequence, or preamble code. Msg3 can also be called the data portion (payload) of the MSGA. Msg3 may include identification information of the terminal device, such as the Serving-Temporary Mobile Subscriber Identity (S-TMSI) or Cell Radio Network Temporary Identifier (C-RNTI) of the terminal device. Optionally, Msg3 may also include other information for random access, which is not limited in this application.

[0081] In other embodiments, the first CG resource is configured with a logical channel-based priority selection rule, and the first PUSCH resource includes at least one of the following:

[0082] Random access response to RAR scheduling of PUSCH resources;

[0083] TC-RNTI scrambled PDCCH scheduling PUSCH resources;

[0084] The PUSCH resource carries message A in a contention-based two-step random access process, wherein message A includes a random access preamble and identification information of the terminal device.

[0085] Example 2: The terminal device uses the first CG resource to transmit data.

[0086] Example 2: Regardless of whether the current state of the first HARQ process is pending or not pending, the terminal device uses the first CG resource to transmit new data.

[0087] Optionally, in this embodiment 2, the first CG resource can be a resource that meets specific conditions, such as the first CG resource not conflicting with the first PUSCH resource, wherein the first PUSCH resource has a higher priority than the first CG resource, or the first PUSCH resource is a specific resource.

[0088] In other words, if the first CG resource meets certain conditions, the terminal device can use the first CG resource to transmit new data, regardless of whether the first HARQ process is suspended.

[0089] The specific implementation of the first PUSCH resource is described in the previous text and will not be repeated here.

[0090] Optionally, in other embodiments, if the first CG resource conflicts with the first PUSCH resource, the terminal device may not use the first CG resource for data transmission.

[0091] Example 3: The terminal device can determine whether to use the first CG resource for data retransmission or new transmission based on the first information.

[0092] In other words, the terminal device can use the first CG resource to retransmit or retransmit data under specific conditions.

[0093] In some embodiments, the first information includes, for example, at least one of the following:

[0094] The state of the first HARQ process;

[0095] Does the first HARQ process contain any untransmitted data?

[0096] The state of the CG retransmission timer;

[0097] The resource location of the first CG resource;

[0098] The first CG resource can carry a transport block size of TB;

[0099] The type of the previous resource corresponding to the first HARQ process;

[0100] Whether the network device has received an instruction message for the first HARQ process;

[0101] The content of the instruction information received from the network device for the first HARQ process.

[0102] Optionally, the state of the first HARQ process may include, but is not limited to, a pending state and a not-pending state.

[0103] Optionally, the state of the first HARQ process can also be understood as the state of the MACPDU (or data) existing in the first HARQ process, such as including but not limited to the pending state and the not pending state.

[0104] Optionally, whether the first HARQ process has untransmitted data can refer to whether the first HARQ process has untransmitted MAC PDUs. The untransmitted data can also be described as data that has not been completely transmitted, data that has not been successfully transmitted, or data that has not been confirmed.

[0105] Optionally, the state of the CG retransmission timer may include, but is not limited to, not configured, not running, configured but not running, running, configured and running, etc.

[0106] Optionally, the determination based on the resource location of the first CG resource may include determining whether the first CG resource conflicts with the first PUSCH resource. The specific implementation of the first PUSCH resource is described in the preceding text and will not be repeated here.

[0107] In some embodiments, the transport block size (TB) that the first CG resource can carry can be expressed as the amount of data that the first CG resource can carry.

[0108] In some embodiments, the indication information sent by the network device to the first HARQ process may be, for example, a resource that is scheduled to use the first HARQ process. This resource may be, for example, a dynamic resource scheduled by DCI, which may be a retransmission resource or a new transmission resource.

[0109] In other embodiments, the indication information sent by the network device to the first HARQ process may also be Downlink Feedback Information (DFI) indication information. The DFI indication information may be, for example, an ACK indication or a Negative Acknowledgement (NACK) indication. Specifically, the indication information sent by the network device is the indication information received during the CG retransmission timer operation (i.e., before timeout).

[0110] Optionally, the content of the network device's indication information to the first HARQ process can be, for example, one of: retransmission scheduling, new transmission scheduling, ACK, and NACK.

[0111] The first CG resource is the resource currently corresponding to the first HARQ process. The MAC entity of the terminal device can assemble packets according to the resource corresponding to the first HARQ process to obtain a MAC PDU, and store the MAC PDU in the cache of the first HARQ process. The previous resource corresponding to the first HARQ process can be, for example, the resource on which the MAC PDU in the cache of the first HARQ process was based when assembling packets. In other words, the previous resource corresponding to the first HARQ process can be the resource of the first HARQ entity that was previously submitted to the terminal device, and the first HARQ entity corresponds to the first HARQ process.

[0112] The following describes, in conjunction with Examples 3-1 and 3-2, some specific implementations of using the first CG resource to perform new transmission or retransmission of data based on the first information.

[0113] Example 3-1:

[0114] As an example, if the first HARQ process is in a not pending state, the terminal device can use the first CG resource to perform new data transmission. The fact that the first HARQ process is not pending indicates that data transmission has already occurred on the first HARQ process; in this case, the first CG resource can be used for new data transmission.

[0115] As another example, if the first HARQ process is in a pending state, the terminal device can use the first CG resource to retransmit data. The first HARQ process being pending can be understood as data on the first HARQ process being packetized but not yet transmitted, or data on the first HARQ process being acquired but not yet transmitted. In this case, the first CG resource can be used to retransmit the data.

[0116] As another example, if there is untransmitted data on the first HARQ process, the terminal device uses the first CG resource to perform new transmission or retransmission of the data. The existence of untransmitted data on the first HARQ process indicates that there is still data to be transmitted on the first HARQ process; in this case, new transmission or retransmission can be used to transmit the untransmitted data.

[0117] As another example, if there is no untransmitted data on the first HARQ process, the terminal device uses the first CG resource to retransmit the data.

[0118] As another example, if there is untransmitted data on the first HARQ process and the first HARQ process is in a suspended state, the terminal device uses the first CG resource to retransmit the data.

[0119] As another example, if there is untransmitted data on the first HARQ process and the first HARQ process is in an unsuspended state, the terminal device uses the first CG resource to retransmit the data.

[0120] As another example, if the first HARQ process is in a suspended state and the previous resource corresponding to the first HARQ process is a CG resource, the terminal device uses the first CG resource to retransmit data.

[0121] As another example, if the network device indicates that the DFI content is NACK for the first HARQ process, then the terminal device uses the first CG resource to retransmit the data.

[0122] As another example, if the network device indicates that the DFI content is ACK for the first HARQ process, then the terminal device uses the first CG resource to retransmit the data.

[0123] As another example, if the network device indicates that the DFI content is NACK for the first HARQ process and the HARQ process is not pending, then the terminal device uses the first CG resource to retransmit the data.

[0124] As another example, if the network device indicates that the DFI content is ACK for the first HARQ process and the HARQ process is not pending, then the terminal device uses the first CG resource to retransmit the data.

[0125] In summary, the terminal device may use the first CG resource to retransmit data when at least one of the following conditions is met: the first HARQ process is in a suspended state;

[0126] The first HARQ process contains untransmitted data;

[0127] The CG retransmission timer is not running;

[0128] The first CG resource does not conflict with the first PUSCH resource;

[0129] The previous resource corresponding to the first HARQ process is a CG resource;

[0130] No instruction information for the first HARQ process was received from the network device;

[0131] The network device indicates a retransmission of the instruction information for the first HARQ process;

[0132] The network device indicates NACK for the first HARQ process.

[0133] Alternatively, the terminal device may use the first CG resource to transmit data when at least one of the following conditions is met:

[0134] The first HARQ process is in an unsuspended state;

[0135] The first HARQ process does not have any untransmitted data;

[0136] The CG retransmission timer is not running;

[0137] The first CG resource does not conflict with the first PUSCH resource;

[0138] Receives instruction information from the network device for the first HARQ process;

[0139] The network device's instruction information to the first HARQ process indicates a new transmission;

[0140] The network device indicates an ACK for the first HARQ process.

[0141] Example 3-2:

[0142] As an example, if the first HARQ process is in a suspended state, the terminal device can use the first CG resource to perform new data transmission. The suspension of the first HARQ process indicates that no data is being transmitted on the first HARQ process; in this case, the first CG resource can be used to perform new data transmission.

[0143] As another example, if the first HARQ process is in an unsuspended state, the terminal device can use the first CG resource for data retransmission. The fact that the first HARQ process is not suspended can be understood as data already being transmitted on the first HARQ process; in this case, the first CG resource can be used for data retransmission.

[0144] As another example, if there is untransmitted data on the first HARQ process, the terminal device uses the first CG resource to perform new transmission or retransmission of the data. The existence of untransmitted data on the first HARQ process indicates that there is still data to be transmitted on the first HARQ process; in this case, new transmission or retransmission can be used to transmit the untransmitted data.

[0145] As another example, if there is no untransmitted data on the first HARQ process, the terminal device uses the first CG resource to retransmit the data.

[0146] As another example, if there is untransmitted data on the first HARQ process and the first HARQ process is in a suspended state, the terminal device uses the first CG resource to retransmit the data.

[0147] As another example, if there is untransmitted data on the first HARQ process and the first HARQ process is in an unsuspended state, the terminal device uses the first CG resource to retransmit the data.

[0148] As another example, if the first HARQ process is in a suspended state and the previous resource corresponding to the first HARQ process is a CG resource, the terminal device uses the first CG resource to transmit new data.

[0149] In summary, the terminal device may use the first CG resource to transmit new data when at least one of the following conditions is met: the first HARQ process is in a suspended state;

[0150] The first HARQ process contains untransmitted data;

[0151] The CG retransmission timer is not running;

[0152] The first CG resource does not conflict with the first PUSCH resource;

[0153] The previous resource corresponding to the first HARQ process is a CG resource;

[0154] No instruction information for the first HARQ process was received from the network device;

[0155] The network device indicates a retransmission of the instruction information for the first HARQ process;

[0156] The network device indicates NACK for the first HARQ process.

[0157] Alternatively, the terminal device may use the first CG resource to retransmit data when at least one of the following conditions is met:

[0158] The first HARQ process is in an unsuspended state;

[0159] The first HARQ process does not have any untransmitted data;

[0160] The CG retransmission timer is not running;

[0161] The first CG resource does not conflict with the first PUSCH resource;

[0162] Receives instruction information from the network device for the first HARQ process;

[0163] The network device's instruction information to the first HARQ process indicates a new transmission;

[0164] The network device indicates an ACK for the first HARQ process.

[0165] Optionally, in some embodiments, the terminal device uses the first CG resource for data retransmission, including:

[0166] The MAC entity of the terminal device will submit the MAC PDU and / or the first CG resource to the HARQ entity corresponding to the first HARQ process.

[0167] The MAC PDU here includes the MAC PDU that has been packaged in the cache of the first HARQ process.

[0168] Optionally, the MAC PDU here includes the packaged MAC PDU corresponding to the previous CG resource in the cache of the first HARQ process. The previous CG resource here refers to the CG resource corresponding to the first HARQ process before the first CG resource, and is not limited to the previous one.

[0169] Optionally, in some embodiments, the terminal device uses the first CG resource to transmit data, including:

[0170] The MAC entity of the terminal device flips the new data indicator (NDI) of the first HARQ process and / or delivers the first CG resource to the HARQ entity corresponding to the first HARQ process.

[0171] In other words, if the aforementioned new transmission conditions are met, the MAC entity of the terminal device can assume that NDI has been flipped, thereby triggering a new transmission of data.

[0172] Therefore, in this embodiment of the application, when the network device only configures the CG retransmission timer corresponding to the CG resource and does not configure the CG timer of the CG resource, the terminal device can use the CG resource to retransmit or retransmit data, or under specific circumstances, use the CG resource to retransmit or retransmit data, thus clarifying the behavior of the terminal device and ensuring data transmission in this scenario.

[0173] Figure 3 This is a schematic interactive diagram of a wireless communication method 300 according to another embodiment of this application, such as... Figure 3 As shown, the method 300 may include at least some of the following:

[0174] S310, the network device generates configuration information for the first configuration authorized CG resource according to the first constraint condition, wherein the configuration information of the first CG resource includes information of the CG timer corresponding to the first CG resource and information of the CG retransmission timer corresponding to the first CG resource, wherein the first constraint condition is used to indicate that the CG timer corresponding to the first CG resource also needs to be configured when configuring the CG retransmission timer corresponding to the first CG resource.

[0175] S320, the network device sends the configuration information of the first CG resource to the terminal device.

[0176] Correspondingly, the terminal device receives the configuration information of the first CG resource sent by the network device.

[0177] Optionally, in some embodiments, the first CG resource can be a resource on unlicensed spectrum. That is, the embodiments of this application can be applied to scenarios where data transmission is performed using resources on unlicensed spectrum, such as the NRU scenarios described above.

[0178] Optionally, in some embodiments, the configuration information of the first CG resource may further include information about the first CG resource, such as the resource's starting position, size, and period. That is, the network device can configure the CG retransmission timer corresponding to the CG resource simultaneously when configuring the CG resource.

[0179] Optionally, the configuration information of the first CG resource can be configured via Radio Resource Control (RRC) signaling. For example, the configuration information of the first CG resource can be carried in the CG configuration (ConfiguredGrantConfig) information element (IE) in the RRC signaling.

[0180] It should be understood that the CG timer and CG retransmission timer in the embodiments of this application correspond to the first HARQ process. In other words, the CG timer and CG retransmission timer are used to limit the use of CG resources by the corresponding first HARQ process.

[0181] In this embodiment, the configuration information of the first CG resource can be generated based on the first constraint condition. The first constraint condition can be used to indicate that the CG timer and CG retransmission timer corresponding to the same CG resource need to be configured together, or that both should be configured or neither should be configured. In other words, when configuring the CG retransmission timer, the CG timer needs to be configured at the same time.

[0182] Optionally, the first constraint can be set in the configuration rules of the CG timer or in the configuration rules of the CG retransmission timer. For example, it can be defined in the domain description of the RRC of the cg-RetransmissionTimer or in the domain description of the RRC of the configuredGrantTimer.

[0183] As an example, the configuration restrictions for configuredGrantTimer could be: "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer or harq-ProcID-Offset. Or, This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer."

[0184] The phrase "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer or harq-ProcID-Offset" indicates that the configuredGrantTimer field is typically used in conjunction with cg-RetransmissionTimer or harq-ProcID-Offset for shared spectrum channel access operations.

[0185] The phrase "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" means that the configuredGrantTimer field is typically used together with cg-RetransmissionTimer for shared spectrum channel access operations.

[0186] The harq-ProcID-Offset represents the HARQ process offset, which is used to determine which HARQ processes are involved in the CG resource.

[0187] As a specific example:

[0188] The domain description for configuredGrantTimer can be:

[0189] "Indicates the initial value of the configured grant timer (see TS38.321[3]) in multiples of periodicity. When cg-RetransmissonTimer is configured, if HARQ processes are shared among different configured grants on the same BWP, configuredGrantTimer is set to the same value for all ofconfigurations on this BWP. This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer".

[0190] "Indicates the initial value of the configured grant timer (see TS 38.321[3]) in multiples of periodicity. When cg-RetransmissonTimer is configured, if HARQ processes are shared among different configured grants on the same BWP, configuredGrantTimer is set to the same value for all of configurations on this BWP."

[0191] The phrase "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" indicates that the configuredGrantTimer field is typically used together with the cg-RetransmissionTimer field for shared spectrum channel access operations.

[0192] The domain description for cg-RetransmissionTimer can be:

[0193] "Indicates the initial value of the configured retransmission timer (see TS 38.321[3]) in multiples of periodicity. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is alwavs configured for operation with shared spectrium channel access together with harq-ProcID-Offset. This field is not configured for operation in licensed spectrum or simultaneously withharq-ProcID-Offset2.If this field is configured, configuredGrantTimer is always configured together".

[0194] The statement “Indicates the initial value of the configured retransmissiontimer (see TS 38.321[3]) in multiples of periodicity. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is always configured for operation with shared spectrum channel access together with harq-ProcID-Offset. This field is not configured for operation in licensed spectrum or simultaneously with harq-ProcID-Offset2” indicates that the initial value of the retransmission timer (see TS 38.321[3]) is specified. The cg-RetransmissionTimer is a multiple of the periodicity. The value of cg-RetransmissionTimer is always less than the value of configuredGrantTimer. This field is always configured with harq-ProcID-Offset for operation with shared spectrum channel access. This field is not configured for operation in licensed spectrum or simultaneously with harq-ProcID-Offset2.

[0195] The phrase "This field is always configured for operation with shared spectrum channel access together with cg-RetransmissionTimer" indicates that the cg-RetransmissionTimer field is typically used together with the configuredGrantTimer field for shared spectrum channel access operations.

[0196] Furthermore, when both the CG timer and the CG retransmission timer corresponding to the first CG resource are configured simultaneously, the terminal device can perform data transmission based on the CG timer and the CG retransmission timer corresponding to the first CG resource.

[0197] For example, after the terminal device sends the first data using the first CG resource, it can start or restart the configured grant timer of the HARQ process. When the terminal device starts the configured grant timer corresponding to the HARQ process, it also starts the cg-retransmission timer corresponding to the HARQ process, wherein the duration of the cg-retransmission timer is shorter than that of the configured grant timer. If no ACK is received before the cg-retransmission timer expires and the configured grant timer has not expired, the terminal device triggers a retransmission of the data using the first CG resource.
