[0083] Figure 1a This is a schematic diagram of the architecture of a communication system provided according to embodiments of this disclosure. Figure 1a As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0084] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0085] In some embodiments, network device 102 may be an access network device. It should be noted that network device 102 may be other types of network devices, such as core network devices.

[0086] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0088] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0089] In some embodiments, the communication system 100 described above may be a 4G communication system, a 5G communication system, or a 6G communication system. It should be noted that the communication system 100 may also be other communication systems, and this disclosure does not specifically limit it.

[0090] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0091] The following embodiments of this disclosure can be applied to Figure 1a The communication system 100 shown, or a part of the main body of the communication system 100, but not limited thereto. Figure 1a The entities shown are illustrative; the communication system 100 may include...

[0092] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0093] Figure 1b This is a schematic diagram of a data transmission model. (For example...) Figure 1bAs shown, SDAP stands for Service Data Adaptation Protocol. PDCP stands for Packet Data Convergence Protocol. RCL stands for Radio Link Control. MAC stands for Medium Access Control.

[0094] like Figure 1b As shown, QoS flow handling is performed at the SDAP entity. Radio carrier compression and security processing are performed at the PDCP entity. RCL channel segmentation and Automatic Repeat Request (Segm.ARQ) are performed at the RLC layer. Logical channel scheduling, multiplexing, and Hybrid Automatic Repeat reQuest (HARQ) are performed at the MAC layer.

[0095] In some embodiments, each logical channel group includes one or more logical channels. The mapping relationship between logical channels and logical channel groups is configured by the network, and a maximum of four logical channel groups can be configured. The network schedules radio resources for the UE to transmit the data according to the BSR.

[0096] In some embodiments, BSR reporting can be triggered by the following conditions:

[0097] 1. When uplink data arrives on a logical channel (LCH), and the logical channel on which the uplink data arrives has a higher priority than the logical channel currently available for transmission, the BSR triggered under this situation is called a regular BSR.

[0098] 2. When uplink data arrives on the logical channel and no data is waiting to be transmitted, the BSR triggered in this situation is called a regular BSR.

[0099] 3. The BSR triggered by the periodic BSR timer timeout is called a periodic BSR.

[0100] 4. A BSR triggered when the retransmission BSR timer times out and there is data waiting to be transmitted in at least one logical channel is called a regular BSR.

[0101] 5. When there are uplink resources available for transmission, and the number of bits used for padding can accommodate the BSR MACCE and the corresponding subheader, the BSR triggered in this case is called a padding BSR.

[0102] In some embodiments, when a terminal lacks network authorization, it requests authorization via a Service Request (SR). After receiving the grant, it reports a Service Request (BSR), and then obtains network authorization to transmit data. Because this process requires several rounds of interaction with the network to obtain authorization, 6G is considering configuring a Configured Grant (CG) for the terminal, allowing it to use CG resources competitively, i.e., Contention-based Configured Grant (CB-CG) resources. However, there is currently no solution regarding how the terminal receives a BSR response when using Contention-based CG.

[0103] Figure 2 This is an interactive schematic diagram of a communication method provided according to an embodiment of this disclosure. The communication method involved in this embodiment can be applied to a communication system 100. Figure 2 As shown, the communication method of this embodiment includes steps S2101 to S2102.

[0104] In step S2101, network device 102 sends an authorization response message through the downlink control channel.

[0105] In some embodiments, terminal 101 obtains an authorization response message by listening to the downlink control channel. The messages on the downlink control channel are scrambled based on the Radio Network Temporary Identifier (RNTI), and the uplink resource requests corresponding to the authorization response messages are sent based on contention for resources.

[0106] In other words, for uplink resource requests sent by terminals based on contention for resources, network devices can send an authorization response message for the uplink resource request via a downlink control channel scrambled with RNTI. Terminals can obtain this authorization response message by listening to the RNTI-scrambled downlink control channel. This allows them to obtain the authorization response message corresponding to uplink resource requests sent based on contention for resources, thus improving communication efficiency.

[0107] In some embodiments, the RNTI is notified to the terminal in advance by the network device, or the RNTI is calculated by the terminal.

[0108] For example, network devices can notify terminals in advance of the RNTI, and terminals can listen to the downlink control channel scrambled by the RNTI, thereby accurately obtaining the grant response message.

[0109] For example, the terminal can calculate the RNTI, and the terminal can listen to the downlink control channel scrambled by the RNTI, thereby accurately obtaining the grant response message.

[0110] For example, the terminal can perform calculations according to the protocol agreement.

[0111] In some embodiments, RNTI is calculated based on the time and / or frequency of uplink resource requests. For example, RNTI can be calculated based on information such as the time and / or frequency at which the terminal sends uplink resource requests on contested resources.

[0112] In some embodiments, the authorization response message includes at least one of the following:

[0113] Identifiers used for conflict resolution;

[0114] Timing Advance (TA);

[0115] Authorization information;

[0116] Effective date of the authorization;

[0117] Authorization attributes;

[0118] Scope of application of the authorization;

[0119] Random number.

[0120] For example, the authorization response message includes an identifier for conflict resolution.

[0121] For example, in some embodiments, the identifier used for conflict resolution may be the terminal's Cell Radio Network Temporary Identifier (CRNTI).

[0122] For example, suppose terminal A and terminal B both send buffer data to a network device based on competing resources. The network device, based on the actual situation, schedules resources for terminal A and includes terminal A's CRNTI in its response. When both terminal A and terminal B receive the network device's response, terminal A obtains its corresponding CRNTI from the response and can therefore use the resources in the response to send data. Conversely, terminal B does not obtain its corresponding CRNTI from the response and therefore cannot use the resources in the response to send data.

[0123] For example, the identifier used for conflict resolution can be a random number.

[0124] For example, a network device can pre-send random numbers to the terminals. For instance, it might send random number 1 to terminal A and random number 2 to terminal B. Assume that both terminal A and terminal B are competing for resources to send buffer data to the network device. Based on the actual situation, the network device schedules resources for terminal A and includes random number 1 in its response. When both terminal A and terminal B receive the network device's response, terminal A obtains its corresponding random number 1 from the response and can therefore use the resources in the response to send data. Conversely, terminal B does not obtain its corresponding random number 2 from the response and therefore cannot use the resources in the response to send data.

[0125] For example, the authorization response message includes a TA (Telematics Acknowledgment). The TA can be used for terminal uplink synchronization. If the requirement is that the TA must be synchronized when the terminal is using CB-CG resources for transmission, then this field is not needed.

[0126] For example, the authorization response message includes authorization information.

[0127] For example, the authorization type may include at least one or a combination of dynamic authorization, type 1 configuration authorization (CG type 1), type 2 configuration authorization, no authorization, or allowing the terminal to refrain from making the request for a period of time.

[0128] For example, the authorization information may include dynamic authorization information, type 1 configuration authorization (CG type 1) information, type 2 configuration authorization (CG type 2) information, and instructions from the network device not to assign authorization or to allow the terminal to refrain from making the request for a period of time, but is not limited to these.

[0129] For example, CG type 1 licensing information may include time and frequency resources, period, modulation and coding scheme, etc. for CG transmission.

[0130] For example, the time-frequency resources, period, and modulation / coding scheme of the CG resources corresponding to the CG type2 license can be notified to the terminal in advance. The CG type2 license information may include an instruction to activate the CG type2 resource, which the terminal will use for subsequent data transmission.

[0131] For example, the authorization response message includes the effective time of the authorization.

[0132] For example, the effective time of the authorization may include the moment of effectiveness (i.e. when it takes effect), the duration of effectiveness (i.e. how long it takes effect), and the moment of expiration (i.e. when it expires).

[0133] For example, the effective time of the authorization may include immediately after the authorization response message is received.

[0134] For example, the effective time of the authorization may include a point in time after the authorization response message is received.

[0135] For example, the effective time of the authorization may include a time period range. For instance, an effective time window.

[0136] For example, the effective time of the authorization may include a periodic effective period.

[0137] It is understandable that the effective time of the authorization and the type of authorization information can be combined. For example, dynamic authorization can take effect immediately, while CG type2 resources can take effect after time T.

[0138] For example, the authorization response message includes authorization attributes to facilitate the terminal's selection of logical channels.

[0139] For example, the authorized attribute may include a subcarrier spacing index. That is, the terminal can transmit data on a logical channel transmitted on that type of subcarrier spacing.

[0140] For example, the authorized attribute may include the Physical Uplink Shared Channel transmission duration (PUSCH transmission duration). That is, the terminal can transmit on a logical channel whose transmission duration meets the requirement.

[0141] For example, the authorized attributes may include a priority index. That is, the terminal can transmit on the logical channel at that priority level.

[0142] For example, the authorized attributes may include uplink hybrid automatic repeat request mode (UL HARQ mode). That is, the terminal can transmit on the logical channel in this HARQ mode.

[0143] For example, the authorization response message may include the scope of the authorization. For example, it may be limited to uplink data transmission on certain logical channels or a list of logical channels only. For example, it may be limited to uplink data transmission on logical channels or a list of logical channels only when urgent or important data is detected.

[0144] For example, the authorization response message may include a random number. This random number could allow the terminal to perform random avoidance and attempt a new attempt.

[0145] For example, if the network device does not assign authorization or allows the terminal to avoid making the request for a period of time, the terminal can avoid making the request for a period of time based on a random number.

[0146] For example, an authorization response message that includes a random number could be a backoff indicator (BI).

[0147] In some embodiments, the RNTI used to scramble the downlink control channel is a common RNTI, and the authorization response message includes the authorization location corresponding to different terminals.

[0148] For example, a network can simultaneously send authorization response messages to multiple terminals. If the format of the authorization response message is a common RNTI, it can indicate the location of each terminal's authorization response. The terminal can first locate its location and then find the corresponding authorization.

[0149] For example, the authorization response message can carry multiple blocks. The terminal finds the corresponding block according to the location indicated by the network and obtains the corresponding authorization at the block location.

[0150] In step S2102, terminal 101 sends the next uplink resource request to network device 102 based on a random number.

[0151] In some embodiments, network device 102 receives a next uplink resource request sent by a terminal, the next uplink resource request being sent based on a random number.

[0152] In some embodiments, if a terminal sends an uplink resource request but no resources are scheduled for it, the terminal may send a next uplink resource request. Although the network device has not scheduled resources for the terminal, it may include a random number in the authorization response message, and the terminal may send a next uplink resource request based on this random number.

[0153] For example, the random number can be a duration, and the terminal can send the next uplink scheduling request after the specified duration.

[0154] In some embodiments, the uplink resource request is the uplink resource request corresponding to the BSR, and the random number is T1; the uplink resource request is the uplink resource request corresponding to the Destination Status Report (DSR), and the random number is T2; T1 is greater than T2.

[0155] For example, a DSR is often the BSR corresponding to an urgent data packet. Therefore, an uplink resource request corresponding to a DSR can avoid fewer events than an uplink resource request corresponding to a BSR, and send the urgent data corresponding to the DSR in a timely manner.

[0169] In some embodiments, the RNTI is notified to the terminal in advance by the network device, or the RNTI is calculated by the terminal.

[0170] In some embodiments, RNTI is calculated based on the time and / or frequency of uplink resource requests.

[0171] In some embodiments, the authorization response message includes at least one of the following: an identifier for conflict resolution; timing advance (TA); authorization information; the effective date of the authorization; the attributes of the authorization; the scope to which the authorization applies; and a random number.

[0172] In some embodiments, the authorization response message includes a random number, and the method further includes sending the next uplink resource request based on the random number.

[0173] In some embodiments, the uplink resource request is the uplink resource request corresponding to the cached status report (BSR) with a random number of T1; the uplink resource request is the uplink resource request corresponding to the destination status report (DSR) with a random number of T2; T1 is greater than T2.

[0174] In some embodiments, the RNTI is a public RNTI, and the authorization response message includes the authorization location corresponding to different terminals.

[0175] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0176] In some embodiments, the terminal obtains uplink authorization through a specific type of resource;

[0177] a) A specific type of resource can be a CB_CG resource;

[0178] In some embodiments, after sending an uplink resource request, the terminal will listen for a specific RNTI to obtain an authorization response;

[0179] a) This specific RNTI can be notified to the terminal in advance by the network; (multiple terminals can share the same RNTI);

[0180] b) The RNTI can be calculated by the terminal according to the protocol agreement, such as the RNTI and information such as the time / frequency of the terminal sending uplink resource requests on a specific type of resource;

[0181] In some embodiments, the authorization response message from the network to the terminal may include a random number to allow the terminal to randomly evade and attempt again.

[0182] a) As one example, the authorization response is BI;

[0183] In some embodiments, the network may include different indication values ​​for different types of terminals:

[0184] a) For example, for a terminal that initiates a BSR, its BI = t1;

[0185] For a terminal that initiates DSR, its BI = t2, where t2 is less than t1, meaning it avoids the problem for a shorter time.

[0186] In some embodiments, the network can simultaneously provide authorization responses to multiple terminals:

[0187] As an example, if the response message bearer format is a common RNTI, it can indicate the location of each terminal's authorization response. That is, the response message can carry multiple blocks. The terminal finds the corresponding block according to the location indicated by the network, and obtains the corresponding authorization at the block location. In other words, the terminal first finds its location, and then finds the corresponding authorization.

[0188] In some embodiments, the authorization response from the network to a terminal may include at least the following fields:

[0189] a) Conflict resolution identifier: This can be a CRNTI or a random number generated by the terminal;

[0190] When the terminal compares the conflict resolution identifier with its own CRNTI or the generated random number, it considers the conflict resolved and has received a correct response from the network.

[0191] b) TA: Used for terminal uplink synchronization. If the terminal is required to synchronize TA when using CB-CG resources for transmission, then this field is not needed;

[0192] As an example, it can be stipulated that when a terminal uses CB-CG resources to send a BSR, TA synchronization must be satisfied.

[0193] c) Uplink authorization;

[0194] Its uplink authorization type may include at least one of the following or a combination thereof:

[0195] 1) Dynamic authorization;

[0196] 2) CG Type 1 license; this includes time and frequency resources, period, modulation and coding scheme, etc. for CG transmission;

[0197] 3) CG type2 authorization, that is, the time and frequency resources, period, and modulation and coding method of CG resources have been notified to the terminal in advance. At this time, it is just an indication to activate the CG type2 resources. The terminal will use the CG type2 resources for subsequent data transmission.

[0198] 4) The base station either does not assign authorization or allows the terminal to circumvent for a period of time before initiating the request again;

[0199] d) Effective date of uplink authorization (when it takes effect + how long it lasts + when it expires):

[0200] The terminal will take effect immediately upon receiving the message.

[0201] Once the terminal receives the authorization response, it will take effect at a certain point in time;

[0202] The effective time can include a time range, such as an effective time window;

[0203] The effective time can include a periodic effective period;

[0204] The above resource categories can be combined, for example, dynamic authorization takes effect immediately and a CG type 2 resource takes effect after time T;

[0205] e) Attributes of uplink authorization:

[0206] This indicates the attributes of the uplink grant, which facilitates logical channel selection by the terminal upon receipt.

[0207] For example: Subcarrier Spacing index; can only be transmitted on logical channels that are limited to this type of subcarrier spacing;

[0208] For example: PUSCH transmission duration; can only be used for transmission on logical channels that meet the transmission duration requirement.

[0209] For example, the priority index can only be transmitted through logical channels that are allowed to transmit at that priority level.

[0210] For example: UL HARQ mode; can only be transmitted on logical channels that allow this HARQ mode;

[0211] f) Scope of application of uplink authorization:

[0212] For example, it can be used only for uplink data transmission on certain logical channels or a list of logical channels.

[0213] For example, uplink data transmission of logical channels or lists of logical channels used only for detecting urgent or important data.

[0214] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, this disclosure proposes an apparatus including units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed, including units or modules for implementing the steps performed by the network device in any of the above methods.

[0215] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit, microprocessor, graphics processing unit (GPU) (which can be understood as a type of microprocessor), or digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device, such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
