Description

Technical Field

[0001] This disclosure generally relates to communication networks, and more specifically, to transmission adaptation in communication networks. Background Technology

[0002] This section introduces various aspects that may help in a better understanding of this disclosure. Accordingly, the statements in this section are to be read in this manner and should not be construed as an admission of what is prior art or what is not prior art.

[0003] Communication service providers and network operators continuously face the challenge of delivering value and convenience to consumers, for example, by providing impressive network services and performance. With the rapid development of networking and communication technologies, wireless communication networks such as Long Term Evolution (LTE) and New Radio (NR) networks promise high service capacity and end-user data rates. In addition to licensed frequency bands, wireless communication networks can also support communication on unlicensed frequency bands to increase network capacity. To meet data transmission requirements, wireless communication networks can implement scheduling processes to allocate radio resources and configure transmissions for terminal devices such as User Equipment (UEs) based on scheduling requests (SRs) and the link quality of the terminal devices. Given the variability of network environment and channel conditions, transmission adaptation is desired to enhance network performance. Summary of the Invention

[0004] This summary is provided to introduce the selected concepts in a simplified form, and the concepts will be described in further detail in the following Detailed Description section. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to limit the scope of the claimed subject matter.

[0005] Wireless communication networks such as 5G / NR can support flexible channel sharing. For different radio devices operating in unlicensed frequency bands, carrier sensing is used to acquire channels in the shared spectrum. To accelerate channel acquisition, autonomous uplink (AUL) transmissions based on configuration scheduling can be introduced for unlicensed operation. For example, after a successful Listen-After-Speak (LBT) procedure, the UE can use a Configuration Grant (CG) to acquire a channel for uplink (UL) transmission. In the event of an initial transmission failure using a CG, the UE can use another CG to implement automatic retransmission without an additional LBT procedure. To achieve link adaptation, it may be necessary to update the transmission mode (e.g., modulation and coding scheme (MCS), transport block size (TBS), etc.) according to changes in the UE's link conditions. However, updating the transmission mode can increase signaling overhead and additional communication latency. Therefore, it may be desirable to achieve transmission adaptation in a more efficient manner.

[0006] Various embodiments of this disclosure propose a solution for supporting transmission adaptation in communication networks. This solution can adjust the transmission mode of UL transmission using CG by indicating the amount of change in transmission parameter values, thereby enabling transmission adaptation for non-dynamic or semi-static scheduling without significantly increasing signaling overhead. Furthermore, the proposed solution can confirm transmission parameter adjustments in a flexible and efficient manner, thereby improving transmission performance and ensuring latency requirements are met.

[0069] The term "terminal device" refers to any end device that can access a communication network and receive services from it. By way of example and not limitation, terminal device can refer to a mobile terminal, user equipment (UE), or other suitable device. A UE can be, for example, a subscriber station, portable subscriber station, mobile station (MS), or access terminal (AT). Terminal devices can include, but are not limited to: portable computers, image capture terminal devices such as digital cameras, gaming terminal devices, music storage and playback devices, mobile phones, cellular phones, smartphones, tablet computers, wearable devices, personal digital assistants (PDAs), vehicles, etc.

[0070] As another specific example, in the Internet of Things (IoT) scenario, a terminal device can also be referred to as an IoT device, and it refers to a machine or other device that performs monitoring, sensing, and / or measurement, and transmits the results of such monitoring, sensing, and / or measurement to another terminal device and / or network device. In this case, the terminal device can be a machine-to-machine (M2M) device, which in the context of the 3rd Generation Partnership Project (3GPP) can be referred to as a machine-type communication (MTC) device.

[0071] As a specific example, a terminal device can be a UE that implements the 3GPP Narrowband Internet of Things (NB-IoT) standard.

[0073] Wireless communication networks are widely deployed to provide a variety of telecommunications services, such as voice, video, data, messaging, and broadcasting. Currently, 5G / NR networks are being developed to achieve maximum flexibility to support a wide range of substantially different use cases. In addition to typical mobile broadband use cases, 5G / NR networks can also support machine-type communication (MTC), ultra-low latency critical communication (URLCC), sidelink device-to-device (D2D), and several other use cases.

[0074] In NR networks, the basic scheduling unit is called a time slot. A time slot consists of 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols for a normal cyclic prefix configuration. NR networks can support many different subcarrier spacing (SCS) configurations, and at a 30 kHz SCS, the OFDM symbol duration is approximately 33 μs. For example, for the same SCS, a time slot with 14 OFDM symbols is 500 μs long (including the cyclic prefix).

[0075] NR networks also support flexible bandwidth configuration for different UEs on the same serving cell. In other words, the bandwidth monitored by the UE and used for its control and data channels can be less than the carrier bandwidth. One or more BWP configurations for each component carrier can be semi-statically signaled to the UE, where a BWP can include a set of consecutive physical resource blocks (PRBs). Several reserved resources can be configured within a BWP. The bandwidth of the BWP can be equal to or less than the maximum bandwidth capability supported by the UE.

[0076] To meet the rapidly increasing network demands for service capacity and data rates, an interesting option in communication technology development is to allow wireless communication networks (such as 5G / NR networks) to operate on unlicensed frequency bands in addition to licensed bands. By aggregating licensed and unlicensed carriers, wireless devices can benefit from the additional transmission capacity offered by unlicensed bands. NR-based access to unlicensed spectrum (NR-U) has been proposed to enable NR networks to operate in unlicensed spectrum that can be shared by various wireless communication systems.

[0077] Allowing unlicensed networks (e.g., networks that can operate in shared or unlicensed spectrum) to effectively utilize available spectrum is an attractive way to increase system capacity. Although the quality of unlicensed spectrum is not well-matched with licensing regimes, allowing the effective use of unlicensed spectrum as a supplement to licensed deployments has the potential to bring significant value to network operators and ultimately the entire communications industry. Certain characteristics of NR may need to be adjusted to conform to the specific characteristics of unlicensed bands and different regulations. SCS at 15kHz or 30kHz are likely the most promising candidates for NR-UOFDM parameter sets (numerologies) for frequencies below 6GHz.

[0078] For operations in unlicensed spectrum, it may be necessary for a device to sense that the medium is free before transmitting. This is often referred to as Listen-Before-Speak, or simply LBT. There are many different styles of LBT, depending on the radio technology used by the device and the type of data the device currently wants to transmit. What all styles have in common is sensing within a specific channel (corresponding to a defined carrier frequency) and over a predefined bandwidth. For example, sensing in the 5 GHz band might be done on a 20 MHz channel. Many devices are capable of transmitting and / or receiving over a wide bandwidth that includes multiple subbands / channels (e.g., LBT subbands (i.e., frequency portions with bandwidth equal to the LBT bandwidth)). Typically, devices are allowed to transmit on subbands where the medium is sensed to be free. Again, when multiple subbands are involved, different styles exist regarding how sensing needs to be performed.

[0079] In principle, the device can operate on multiple sub-bands in two ways. One approach is that the transmitter / receiver bandwidth can be varied depending on which sub-bands are perceived as idle. In this setup, there is only one component carrier (CC), and multiple sub-bands are treated as a single channel with a large bandwidth. The other approach is that the device operates a nearly independent processing chain for each channel. Depending on the degree of independence of the processing chains, this option may be referred to as carrier aggregation (CA) or dual connectivity (DC).

[0080] As previously mentioned, the channel access procedure in unlicensed NR spectrum can utilize the LBT mechanism to acquire a channel for transmission. The LBT mechanism is designed for unlicensed spectrum coexisting with other Radio Access Technologies (RATs). In this mechanism, the radio equipment can apply an Empty Channel Assessment (CCA) check (i.e., channel awareness) before any transmission. The transmitter involves energy detection (ED) over a period of time compared to a specific threshold (e.g., the ED threshold) to determine if the channel is idle. If the channel is determined to be occupied, the transmitter can implement random backoff within the contention window before the next CCA attempt. To protect acknowledgment (ACK) transmissions, the transmitter can delay for a period after each busy CCA slot before resuming backoff. Once the transmitter has acquired access to the channel, it is allowed to transmit for the maximum achievable duration (i.e., Maximum Channel Occupancy Time (MCOT)). To differentiate Quality of Service (QoS), channel access priorities based on service type can be defined. For example, four LBT priority categories can be defined to differentiate between Contention Window Size (CWS) and MCOT between services.

[0081] For NR-U, scheduling schemes such as configuration scheduling and dynamic scheduling can be used. According to an exemplary embodiment, configuration scheduling can be used in the NR network to allocate semi-static periodic allocations or grants to the UE. For UL, there are two types of configuration scheduling schemes: Type 1 and Type 2. For Type 1, some configuration grants (CGs) are configured only via RRC signaling. For Type 2, a configuration process similar to that of SPS UL in the LTE network is defined, i.e., some parameters are pre-configured via RRC signaling, and some physical layer parameters are configured via the Media Access Control (MAC) scheduling process. Configuration scheduling can also be used for NR unlicensed operations. For NR-U, configuration scheduling can significantly improve the channel access probability for Physical Uplink Shared Channel (PUSCH) transmissions because it avoids the additional LBT process for each UL-granted Physical Downlink Control Channel (PDCCH) transmission, and the UE can use the CG to acquire a channel for PUSCH transmission after the LBT process is successful. In this UL transmission process, only a single LBT process is required compared to the three LBT processes that rely on the Scheduling Request / Buffer Status Report (SR / BSR) process (one for Scheduling Request (SR) transmission, one for PDCCH for UL authorization, and one for PUSCH transmission).

[0082] According to some exemplary embodiments, for NR in unlicensed spectrum, it is beneficial to allow temporally continuous CG resources without any gaps between resources, as well as non-continuous CG resources (not necessarily periodic) with gaps between resources. Furthermore, specific enhancements to configuration scheduling, such as AUL, can be applied to NR-U.

[0083] In NR networks, for Type 1CG, the UE can apply the MCS / TBS configured by the gNB to CG-based transmissions via RRC signaling. When a transmission mode update (e.g., MCS / TBS) is required, the gNB can send RRC reconfiguration signaling to the UE including the new MCS / TBS. This can be slow and cannot provide fast transmission adaptation for the UE based on changes in the UE's link conditions. For Type 2CG, the gNB can update transmission parameters in the active DCI for the UE. Upon receiving the active DCI for Type 2CG, the UE can provide an acknowledgment MAC CE to the gNB on the reverse link. However, frequently sending active DCIs to update transmission parameters for Type 2CG is not a good option for the gNB, as this may deviate from the design purpose of active DCIs (which operate in a more semi-static manner), and it may also introduce high signaling overhead to the PDCCH. Therefore, for both types of CG configuration schemes, the existing mechanisms are insufficient to achieve fast and reliable updates of transmission parameters for CG.

[0084] According to some embodiments, there may be two options for updating the transmission parameters of the CG: a gNB-based option and a UE-based option. In the gNB-based option, transmission parameters (e.g., MCS, RI, PMI, Sounding Reference Signal Index (SRI), etc.) can be indicated in the Configuration Grant Downlink Feedback Information (CG-DFI). For this option, the DCI signaling overhead is not significantly affected because the gNB needs to provide Hybrid Automatic Repeat Request Acknowledgment / Negative Acknowledgment (HARQ A / N) in the CG-DFI signaling anyway. In the UE-based option, the UE can indicate some transmission parameters (e.g., MCS, PMI, RI, SRI, etc.) in the Configuration Grant Uplink Control Information (CG-UCI) to improve transmission efficiency. For either of these options, directly including transmission parameters in the UCI or DFI may increase signaling overhead. On the other hand, if the UE or gNB receives an update to the transmission parameters, the UE or gNB may need to acknowledge receiving the updated parameters and apply them accordingly.

[0085] To reduce signaling overhead for updating transmission parameters and improve resource efficiency of communication networks, various exemplary embodiments of this disclosure propose transmission adaptive solutions for UL transmissions with CG (e.g., PUSCH transmissions). The proposed solutions enable transmission parameter updates to be indicated by signaling messages such as DFI / DCI / UCI in an efficient manner, thereby reducing signaling overhead in DFI / DCI / UCI with improved resource utilization. Furthermore, the proposed solutions allow the UE / gNB to acknowledge receipt of transmission parameter updates and apply the updated parameters accordingly without significantly increasing processing complexity.

[0086] According to some exemplary embodiments, transmission adaptation can be triggered or initiated by either the gNB or the UE (i.e., gNB-based transmission adaptation or UE-based transmission adaptation). The gNB can be configured to enable either the gNB or the UE to trigger transmission adaptation. This configuration can be per cell / carrier / BWP / channel / UE / CG. According to exemplary embodiments, the gNB can, for example, inform the UE whether gNB-based or UE-based transmission adaptation is enabled in a DL signaling message such as DCI / DFI.

[0087] According to some exemplary embodiments, for gNB-based transmission adaptation, transmission parameter adjustments, such as those for UE MCS adjustment, can be signaled by the gNB via one or more bits in DFI / DCI / MAC CE / RRC signaling. For UE-based transmission adaptation, transmission parameter adjustments, such as those for UE MCS adjustment, can be signaled by the UE via one or more bits in UCI / MAC CE / RRC signaling. According to embodiments, a single bit in DCI / DFI / UCI / MAC CE / RRC signaling can be used to indicate MCS adjustment for the UE or a group of UEs. For example, a value of 1 indicates that the MCS value increases by a given step (e.g., the MCS index increases by 1), and a value of 0 indicates that the MCS value decreases by a given step (e.g., the MCS index decreases by 1). According to embodiments, for example, the increase / decrease step size can be preconfigured for each transmission parameter or a group of transmission parameters. It is understood that although some embodiments have been described in the context of MCS adjustment, other transmission parameters (e.g., RI, PMI, SRI, etc.) can also be updated / adjusted using methods according to various embodiments of this disclosure.

[0088] According to some exemplary embodiments, the transmission adaptive configuration can be configured per cell / carrier / BWP / channel / subband / UE / CG. MCS adjustments carried by DCI / DFI / UCI / MAC CE / RRC signaling can be applied to one or more scheduling / resource configurations. Optionally, the DCI / DFI / UCI / MAC CE / RRC signaling can also indicate one or more types of parameters for which adjustments need to be applied. For example, the DCI / DFI / UCI / MAC CE / RRC signaling can carry an indicator of a specific parameter type for adjustment, thereby allowing adjustments to be applied to the specified parameter type. In another example, the DCI / DFI / UCI / MAC CE / RRC signaling may not indicate any parameter type for adjustment, meaning that adjustments apply to all relevant transmission parameters.

[0089] According to an exemplary embodiment, the gNB can configure a set of candidate transmission parameter values ​​for, for example, MCS, RI, and MCS tables via RRC signaling. The gNB can select candidate values ​​from the set of candidate transmission parameter values ​​and indicate the selected value to the UE, for example, via a DL signaling message such as DCI / DFI, which may carry the corresponding index of the selected value. Similarly, for UE-based transmission adaptation, the UE can select candidate values ​​for transmission parameters from the set of candidate transmission parameter values ​​configured by the gNB and transmit the corresponding index of the selected value in a UL signaling message such as UCI.

[0090] In another exemplary embodiment, the gNB can use an indicator in the first DFI to indicate to the UE whether to use the second DFI to update the transmission parameters. According to this embodiment, the second DFI can enable the reconfiguration of the corresponding transmission parameters. If the UE is instructed to update the transmission parameters when it receives the first DFI, the UE can further receive the second DFI to detect the corresponding new transmission parameters and / or changed values ​​of the transmission parameters. This avoids the fixed overhead caused by including transmission parameters and HARQ A / N in the same DFI.

[0091] Figure 1 This is a diagram illustrating an example of transmission parameter adjustment according to an embodiment of the present disclosure. Figure 1 The examples shown are applicable to NR scenarios where the UE operates on an unlicensed carrier. It should be understood that the exemplary transmission parameter adjustments are also applicable to other scenarios where the communication network can operate on licensed spectrum and apply or support various radio interface technologies (not limited to LTE and NR technologies).

[0092] exist Figure 1In the example shown, orthogonal overlay codes (OCC) or cyclic shifts can be used to multiplex DFI 0 for UE 0, DFI 1 for UE 1, DFI 2 for UE 2, and DFI M. DFI M can be scheduled by DFI 0 / 1 / 2 for transmission parameter adjustments for UE 0 / 1 / 2. According to an exemplary embodiment, a first DFI such as DFI 0 / 1 / 2 may only carry HARQ A / N, while a second DFI such as DFI M following the first DFI may carry updated transmission parameters and / or a set of changed values ​​for the transmission parameters. Figure 1 As shown, UE x (x = 0, 1, or 2) can receive both DFI x and DFI M simultaneously or at different times. UE x can then first decode DFI x. If DFI x indicates that DFI M was sent for UE x, the UE can further decode DFI M to derive new transmission parameters. If DFI x indicates that DFI M was not sent for UE x, the UE can discard the received signal for DFI M without decoding. Optionally, DFI M can be shared by DFI 0 / 1 / 2. This means that DFI 0 / 1 / 2 can be UE-specific signaling messages, while DFI M can be addressed to a group of UEs.

[0093] According to some exemplary embodiments, the UE may have multiple active CG configurations. These CG configurations may be in the same or different carrier / LBT subbands. The gNB may use DFI (such as...) Figure 1 The DFI / DCI or DCI shown can be used to indicate a change in transmission parameters for all or a subset of active CG configurations. Similarly, the UE can use a UCI to indicate a change in transmission parameters for at least a subset of active CG configurations. According to an embodiment, a bitmap can be defined in the DFI / DCI / UCI to indicate which CG configuration(s) will have their transmission parameter changes applied via signaling through the DFI / DCI / UCI. In another embodiment, the DFI / DCI / UCI can carry a CG configuration index to indicate the corresponding CG configuration for which the transmission parameter change will be applied. As yet another option, a HARQ process identifier (ID) can be signaled in the DFI / DCI / UCI to indicate which HARQ process needs to change its transmission parameters. The indicated HARQ process can be associated with an active CG configuration.

[0094] In response to receiving a DFI / DCI indicating a change in transmission parameters, the UE can determine when to apply one or more new transmission parameters, such as a time offset (e.g., x radio frames / slots / OFDM symbols), after deriving new transmission parameters based on the received DFI / DCI. According to an exemplary embodiment, the time offset can be indicated in the DFI / DCI, which signals the change in transmission parameters to the UE. Optionally or additionally, the UE can determine when to use the new transmission parameters in the next transmission after the UE has sent an acknowledgment to the gNB regarding the receipt of the DFI / DCI. According to an exemplary embodiment where transmission adaptation is triggered by the UE, the UE can inform the gNB of the time when it will use the new transmission parameters in a UL signaling message (e.g., UCI).

[0095] According to some exemplary embodiments, when pending HARQ transmissions exist, the UE can receive or choose to adjust transmission parameters (e.g., MCS, RI, PMI, SRI, etc.). If the UE receives a negative acknowledgment (NACK) for a pending HARQ transmission / retransmission, the UE can use the previous transmission parameters to trigger a HARQ retransmission without adjusting the transmission parameters. According to exemplary embodiments, the new transmission parameters can be applied to new CG initial transmissions and their potential retransmissions.

[0096] It is understood that, in addition to DFI / DCI / UCI or alternatives to DFI / DCI / UCI, indicators for transmission parameter adjustments (e.g., actual changed values, indexes of changed values, indexes of new values, etc.) according to various embodiments can also be signaled via MAC CE and / or RRC signaling messages. In response to receiving a DFI / DCI / UCI / MAC CE / RRC signaling message indicating transmission parameter adjustments, the gNB (or UE) can provide acknowledgment to the UE (or gNB).

[0097] According to an exemplary embodiment, where a transmission parameter adjustment for the corresponding CG configuration is carried in a downlink (DL) signaling message such as DFI, the UE can utilize an existing CG acknowledgment MAC CE to acknowledge receipt of the transmission parameter adjustment. The existing CG acknowledgment MAC CE may need to be updated to include an indicator indicating whether the acknowledgment is for a DFI carrying the transmission parameter adjustment or for a DCI carrying an activation / deactivation command for the CG. Optionally, one or more reserved bits in the MAC subheader can be redefined for this purpose.

[0098] Optionally or additionally, a new MAC CE may be defined to acknowledge receipt of a DFI carrying transmission parameter adjustments for one or more CG configurations. According to some exemplary embodiments, the new MAC CE may indicate / carry a CG configuration index or a bitmap of the CG configuration to acknowledge receipt of the corresponding changed transmission parameter value. Optionally, the new MAC CE may indicate / carry the cell / carrier / BWP / subband / channel associated with the corresponding CG configuration.

[0099] In the case of UE-based transmission adaptation, the UE can transmit new transmission parameters and / or change the values ​​of transmission parameters in a UL signaling message (e.g., UCI). The gNB can acknowledge the UCI received from the UE using a MAC CE (e.g., a reused CG acknowledgment MAC CE or a new MAC CE). Optionally, a CG configuration index or bitmap indicating the relevant CG configuration can be indicated / carried in the MAC CE. In an exemplary embodiment, the cell / carrier / BWP / subband / channel associated with the corresponding CG configuration can be indicated / carried in the MAC CE.

[0100] It is understood that although various embodiments of this disclosure are described in the context of NR unlicensed spectrum (NR-U), the solutions proposed according to exemplary embodiments are not limited to NR-U scenarios. The proposed solutions are also applicable to other unlicensed operation scenarios, such as LTE Licensed Assisted Access (LAA), Enhanced Licensed Assisted Access (eLAA), Further Enhanced Licensed Assisted Access (feLAA), MuLteFire, etc. Furthermore, it is recognized that the solutions proposed according to exemplary embodiments are also applicable to licensed operation scenarios, where adjustments to one or more transmission parameters (e.g., MCS, RI, PMI, SRI, etc.) may need to be made via signal transmission in a resource-efficient manner.

[0101] Figure 2 This is a flowchart illustrating a method 200 according to some embodiments of the present disclosure. Figure 2 The method 200 shown can be implemented by a network node or a means communicatively coupled to a network node. According to an exemplary embodiment, the network node may include a base station such as an eNB / gNB. The network node can configure radio resources and schedule transmissions for terminal devices such as UEs. For example, the network node can allocate radio resources to the terminal device and issue UL grants (e.g., static grants, CGs, semi-static grants, or dynamic grants) to schedule UL transmissions from the terminal device. According to an exemplary embodiment, the network node can provide a semi-static scheduling configuration for the terminal device and initiate transmission parameter adjustments for the semi-static scheduling configuration.

[0102] according to Figure 2In the exemplary method 200 shown, a network node can determine the amount of adjustment to parameters used for transmission from a terminal device to the network node, as shown in box 202. In this embodiment, the transmission from the terminal device to the network node can be based at least in part on a semi-static scheduling configuration (e.g., CG configuration) of the terminal device by the network node. The network node can then send signaling information to the terminal device to indicate the amount of parameter adjustment, as shown in box 204.

[0103] According to some exemplary embodiments, the signaling information sent by the network node may include at least one of DCI, DFI, MAC CE, and RRC signaling messages. It is understood that the signaling information may also be carried in other suitable types of messages from the network node to the terminal device. According to exemplary embodiments, the amount of parameter adjustment may be indicated by one or more bits in the signaling information. To reduce signaling overhead, the amount of parameter adjustment may include a specific increment or decrement of the parameter value. For example, the specific increment or decrement may be an actual change in value, or a given step size corresponding to a range of changed values. It is appreciated that although various embodiments have been described with respect to scenarios where the relative change in parameter value is indicated by signaling information, the solutions proposed according to exemplary embodiments are also applicable to scenarios where the absolute value of the updated parameter or its index is signaled for transmission adaptation.

[0104] According to some exemplary embodiments, by indicating the adjustment amount of a parameter through signaling information sent from a network node, a terminal device can adjust a parameter corresponding to that adjustment amount, and / or one or more other parameters used for transmission from the terminal device to the network node. These parameters may include various transmission parameters, such as MCS, RI, PMI, SRI, etc. Optionally, the signaling information may indicate at least one of the parameter and the one or more other parameters. Thus, the terminal device can know which(s) parameter(s) may need to be updated. Optionally or additionally, the signaling information may not indicate any parameter, meaning that all parameters used for transmission from the terminal device to the network node may need to be adjusted.

[0105] According to some exemplary embodiments, adjustments to the one or more other parameters may be at least partially based on adjustments to the parameters. For example, an increase in the current value of the parameter may mean that the current values ​​of the one or more other parameters may also need to be increased. If signaling information instructs the terminal device to decrease the current value of the parameter by an adjustment amount, the current values ​​of the one or more other parameters may also need to be decreased accordingly. Optionally, the signaling information may indicate when the terminal device will apply the adjustment amount to the parameter.

[0106] According to some exemplary embodiments, the parameter adjustment amount can be determined or configured on a per-cell, per-carrier, per-BWP, per sub-band, per-channel, per-terminal device, or per semi-static scheduling configuration basis. Optionally, the parameter adjustment amount can be applied to one or more semi-static scheduling configurations. According to exemplary embodiments, signaling information can indicate the one or more semi-static scheduling configurations by using bitmaps, indexes, HARQ process identifiers, and / or any other suitable indicators.

[0107] According to some exemplary embodiments, the adjustment amount of the parameter can be selected from a set of candidate adjustment amounts that can be used for the parameter. For example, the set of candidate adjustment amounts can be pre-configured to the terminal device via RRC signaling from the network node. The network node can reconfigure the transmission parameters of the terminal device by selecting a target value from the set of candidate adjustment amounts and signaling the selected value to the terminal device.

[0108] According to some exemplary embodiments, network nodes can transmit the first DFI (such as...) Figure 1 The DFI 0 / 1 / 2 in the data is sent to the terminal device, and as follows: Figure 2 The signaling information described in box 204 can be carried in a second DFI (such as...) from the network node to the terminal device. Figure 1 In the DFI (Device Filtering Information), the first DFI can instruct the terminal device how to process the second DFI. For example, if the first DFI indicates that the second DFI carries an adjustment amount for parameters of the terminal device, the terminal device can decode the second DFI to obtain the adjustment amount of the parameters. If the first DFI indicates that the parameters of the terminal device have not been updated, or the second DFI is not targeted at the terminal device, the terminal device can discard the second DFI, or the terminal device may not even receive the second DFI (e.g., if the first DFI and the second DFI are sent at different times). Optionally, the second DFI can be shared by the terminal device with one or more other terminal devices.

[0109] According to some exemplary embodiments, a network node can receive a MAC CE from a terminal device to confirm that the terminal device has received signaling information. Optionally, the MAC CE may indicate at least one of semi-static scheduling configuration, cell, carrier, BWP, sub-band, and channel to confirm that the terminal device has received an adjustment amount of the associated parameter.

[0110] According to some exemplary embodiments, a network node can receive transmissions from a terminal device, and the parameters used for these transmissions can be adjusted according to the amount of parameter adjustment. Transmissions from the terminal device to the network node are used for the terminal device's UL (Ultimate Flow) services, and no transmissions for UL services are scheduled to the network node until the network node receives a MAC (Confirmation of Acceptance) CE from the terminal device. That is, the terminal device can use the adjusted / updated transmission parameters for newly scheduled initial transmissions and their potential retransmissions, but not for pending HARQ (Hardware Arrangement Request) transmissions / retransmissions.

[0111] According to some exemplary embodiments, a network node can send configuration information to a terminal device to indicate whether the network node or the terminal device can initiate adjustments to the transmission parameters used by the terminal device. In this case, whether to trigger network node-based transmission adaptation or terminal device-based transmission adaptation configuration can be controlled at least in part by the network node.

[0112] It should be noted that this disclosure primarily describes some embodiments relating to the LTE or NR specifications, which are used as non-limiting examples of specific exemplary network configurations and system deployments. Thus, the description of the exemplary embodiments given herein specifically refers to terms directly related to them. Such terms are used only in the context of the presented non-limiting examples and embodiments and are not intended to limit this disclosure in any way. Rather, any other system configuration or radio technology may be equally utilized, provided that the exemplary embodiments described herein are applicable.

[0113] Figure 3 This is a flowchart illustrating a method 300 according to some embodiments of the present disclosure. Figure 3 The method 300 shown can be implemented by a terminal device or a means communicatively coupled to the terminal device. According to an exemplary embodiment, a terminal device such as a UE can be implemented by a network node (e.g., regarding...). Figure 2 The described network node is configured with radio resources in licensed and / or unlicensed frequency bands. For example, a terminal device can obtain UL authorization (e.g., static authorization, CG, semi-static authorization, or dynamic authorization) from the network node to schedule UL transmissions. According to an exemplary embodiment, the terminal device may be provided with one or more semi-static scheduling configurations by the network node to save signaling overhead and improve latency performance.

[0114] according to Figure 3The exemplary method 300 shown allows a terminal device to receive signaling information from a network node indicating adjustments to parameters used for transmissions from the terminal device to the network node, as shown in block 302. The transmission from the terminal device to the network node may be based at least in part on a semi-static scheduling configuration of the terminal device by the network node. Optionally, in response to receiving the signaling information, the terminal device may process the signaling information, as shown in block 304. For example, processing of the signaling information by the terminal device may include decoding or discarding the signaling information. It should be noted that... Figure 3 The operation / steps of method 300 shown can correspond to Figure 2 The operation / steps of method 200 shown, and the signaling information received by the terminal device in block 302 can correspond to the signaling information sent by the network node in block 204.

[0115] According to some exemplary embodiments, a terminal device may receive a first DFI from a network node to instruct how to process a second DFI from the network node. (As in conjunction with...) Figure 2 The signaling information from the network node can be carried in a second DFI, which can be shared by the terminal device and one or more other terminal devices.

[0116] According to some exemplary embodiments, the terminal device may send a MAC CE to the network node to acknowledge receipt of signaling information. Optionally, the semi-static scheduling configuration / cell / carrier / BWP / subband / channel associated with the adjustment amount of the received parameters may be indicated in the acknowledgment MAC CE from the terminal device. Based on the adjustment amount of the parameters, the terminal device may adjust / update the parameter values ​​and implement the corresponding transmission of UL services from the terminal device to the network node. In embodiments, no transmissions for UL services have been scheduled to the network node before the acknowledgment MAC CE is transmitted from the terminal device to the network node.

[0117] According to some exemplary embodiments, the initiator of the transmission adaptation can be dynamically configured or changed. (See also: Regarding...) Figure 2 As described, the terminal device can receive configuration information from the network node, and the configuration information can enable the network node or the terminal device to initiate adjustments to the transmission parameters used by the terminal device.

[0118] Figure 4 This is a flowchart illustrating a method 400 according to some embodiments of the present disclosure. Figure 4 The method 400 shown can be implemented by a terminal device or a means communicatively coupled to the terminal device. According to an exemplary embodiment, a terminal device, such as a UE, is capable of initiating adjustments to transmission parameters for the terminal device. It can be understood that, as with respect to… Figure 4 The described terminal device can also be configured to implement Figure 3 Method 300 is shown. Similarly, in cases where the terminal device is equipped with the ability to trigger transmission adaptation, as per [the relevant information]... Figure 3 The described terminal equipment can also be implemented. Figure 4 Method 400 is shown.

[0119] according to Figure 4 In the exemplary method 400 shown, the terminal device can determine the adjustment amount of parameters for transmission from the terminal device to the network node, as shown in box 402. The transmission from the terminal device to the network node can be based at least in part on a semi-static scheduling configuration (e.g., CG configuration) of the terminal device by the network node. The terminal device can then send signaling information to the network node to indicate the adjustment amount of the parameters, as shown in box 404. According to some exemplary embodiments, the signaling information sent by the terminal device may include at least one of UCI, MAC CE, and RRC signaling messages.

[0120] Understandable, regarding Figure 4 The described signaling information may have information related to... Figure 2 and Figure 3 The described signaling information has the same or similar configuration / format / function. (Combined) Figure 2 and Figure 3 The various embodiments of the described signaling information can also be applied to combining Figure 4 The signaling information described.

[0121] according to Figure 4 The exemplary method 400 shown can inform the network node terminal device that it will adjust at least one of the following by indicating the adjustment amount of a parameter through signaling information sent from the terminal device: the parameter corresponding to the adjustment amount, and one or more other parameters for transmission from the terminal device to the network node.

[0122] According to some exemplary embodiments, a terminal device can receive a MAC CE from a network node to confirm that the network node has received signaling information. Optionally, the MAC CE may indicate the amount of adjustment of parameters received by the network node for the associated resource and transport configuration (e.g., semi-static scheduling configuration, cell, carrier, BWP, sub-band, channel, etc.).

[0123] According to some exemplary embodiments, a terminal device can implement a transmission from the terminal device to a network node using parameters adjusted according to the amount of parameter adjustment. In an exemplary embodiment, the transmission from the terminal device to the network node is for the terminal device's UL service, and no transmission for the UL service has been scheduled to the network node before the terminal device receives an acknowledgment MAC CE from the network node.

[0124] Figure 5This is a flowchart illustrating a method 500 according to some embodiments of the present disclosure. Figure 5 The method 500 shown can be implemented by a network node or a means communicatively coupled to a network node. According to an exemplary embodiment, a network node, such as a base station, can be a terminal device (such as a device connected to...). Figure 4 The described terminal equipment is configured with radio resources and transmission scheduling. It is understood that, as regarding... Figure 2 The described network nodes can also be configured to implement Figure 5 Method 500 is shown. Similarly, in cases where network nodes are equipped with the ability to trigger transmission adaptation, as per [the relevant information]... Figure 5 The described network nodes can also be implemented. Figure 2 Method 200 is shown.

[0125] according to Figure 5 The exemplary method 500 shown allows a network node to receive signaling information from a terminal device indicating adjustments to parameters used for transmission from the terminal device to the network node, as shown in block 502. (As in conjunction with...) Figure 4 The transmission can be at least partially based on a semi-static scheduling configuration of the terminal device by the network node. Optionally, in response to receiving signaling information, the network node can process the signaling information, as shown in block 504. For example, the processing of the signaling information by the network node may include decoding the signaling information (e.g., UCI, MAC CE, RRC signaling messages, etc.) and obtaining the adjustment amount of the parameters indicated by the signaling information. Thus, the signaling information can inform the network node that the terminal device will adjust one or more parameters used for UL transmission. It should be noted that... Figure 5 The operation / steps of method 500 shown can correspond to Figure 4 The operation / steps of method 400 shown, and the signaling information received by the network node in block 502 can correspond to the signaling information sent by the terminal device in block 404.

[0126] According to some exemplary embodiments, a network node may send a MAC CE to a terminal device to acknowledge that the network node has received signaling information. In response to the acknowledgment that the network node has received the signaling information and the corresponding parameter adjustment amount, the terminal device may use the adjusted / updated parameters to perform UL transmission to the network node. Optionally, the acknowledgment MAC CE from the network node may indicate one or more resources and transmission configurations associated with the adaptive transmission initiated by the terminal device.

[0127] According to some exemplary embodiments, a network node can receive transmissions for UL services using adjusted parameters from a terminal device. According to an exemplary embodiment, no transmissions for UL services are scheduled to the network node before the MAC CE is confirmed to have been transmitted from the network node to the terminal device.

[0128] The proposed solution, according to one or more exemplary embodiments, enables transmission adaptation for UL transmissions in a semi-static scheduling configuration with less overhead, thereby allowing network nodes and / or terminal devices to adapt transmission parameters to communication conditions more quickly and flexibly. According to some exemplary embodiments, when one of the base station and the UE triggers transmission adaptation to adjust at least one parameter of a UL transmission with CG, the changed value or adjustment amount of that parameter can be signaled to the other of the base station and the UE. According to the proposed solution, there is no need to directly signal the new transmission parameter. In some cases, using only one bit to indicate the adjustment amount of the transmission parameter is sufficient, which effectively reduces the overhead of signaling messages (e.g., DFI, DCI, UCI, MAC CE, RRC signaling, etc.). Furthermore, according to the proposed solution, network nodes and / or terminal devices can more easily acknowledge receipt of signaling messages indicating transmission parameter adjustments. Therefore, autonomous UL HARQ retransmission performance can be enhanced while ensuring latency requirements are met.

The access network 911 includes multiple base stations 912a, 912b, 912c, such as NBs, eNBs, gNBs, or other types of wireless access points, each defining a corresponding coverage area 913a, 913b, 913c. Each base station 912a, 912b, 912c can be connected to the core network 914 via a wired or wireless connection 915. A first UE 991 located in coverage area 913c is configured to wirelessly connect to or be paged by the corresponding base station 912c. A second UE 992 in coverage area 913a can wirelessly connect to the corresponding base station 912a. Although multiple UEs 991, 992 are shown in this example, the disclosed embodiments are equally applicable to situations where a single UE is in a coverage area or a single UE is connected to a corresponding base station 912.

[0137] Telecommunications network 910 is connected to host computer 930, which may be embodied in the hardware and / or software of a standalone server, a cloud-implemented server, a distributed server, or as processing resources in a server cluster. Host computer 930 may be owned or controlled by a service provider, or may be operated by or on behalf of the service provider. Connections 921 and 922 between telecommunications network 910 and host computer 930 may extend directly from core network 914 to host computer 930, or may traverse an optional intermediate network 920. Intermediate network 920 may be one or a combination of public networks, private networks, or hosted networks; intermediate network 920 (if any) may be a backbone network or the Internet; in particular, intermediate network 920 may include two or more subnetworks (not shown).

[0138] Figure 9 The communication system generally implements the connection between the connected UEs 991 and 992 and the host computer 930. This connection can be described as an over-the-top (OTT) connection 950. The host computer 930 and the connected UEs 991 and 992 are configured to transmit data and / or signaling via the OTT connection 950 using access network 911, core network 914, any intermediate network 920, and possibly other infrastructure (not shown) as intermediaries. The OTT connection 950 can be transparent in terms of the fact that the participating communication devices are unaware of the routes of uplink and downlink communications. For example, the base station 912 may not be informed or need not be informed of the past routes of incoming downlink communications originating from the host computer 930 that are to be forwarded (e.g., switched) to the connected UE 991. Similarly, the base station 912 does not need to know the future routes of outgoing uplink communications originating from the UE 991 toward the host computer 930.

The client application 1032 is operable to provide services to human or non-human users via the UE 1030, with the support of the host computer 1010. In host computer 1010, the executing host application 1012 can communicate with the executing client application 1032 via an OTT connection 1050 terminated between UE 1030 and host computer 1010.
