[0034] It should be understood that although the terms first, second, third, etc. may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0035] The following describes the application scenarios of this application:

[0036] Figure 1 A block diagram of a communication system provided by an exemplary embodiment of the present application is shown. The communication system may include: a terminal 10 and a network device 20.

[0037] There are usually multiple terminals 10, and one or more terminals 10 can be distributed in each cell managed by each network device 20. The terminals 10 can include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminals.

[0038] Network device 20 is a device deployed in an access network to provide wireless communication capabilities for terminal 10. Network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different wireless access technologies, the names of devices that provide network device functionality may vary. For example, in 5G NR systems, they are referred to as gNodeBs or gNBs. As communication technologies evolve, the term "network device" may change. For ease of description, in the embodiments of this application, the aforementioned devices that provide wireless communication capabilities for terminal 10 are collectively referred to as network devices. A connection can be established between network device 20 and terminal 10 via an air interface, enabling communication, including signaling and data exchange, via this connection. There can be multiple network devices 20, and two adjacent network devices 20 can communicate via wired or wireless means. Terminal 10 can switch between different network devices 20, i.e., establish connections with different network devices 20.

[0039] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in the embodiments of the present application may be applicable to the 5G NR system or to subsequent evolution systems of the 5G NR system.

[0040] In some embodiments, the present application proposes an NTN system using NR, such as Figure 2 As shown, the NTN system includes a terminal 10 , a network device 20 and a transfer device 30 .

[0041] Optionally, the transfer device 30 may be a satellite, a drone, or other device with a transfer function, which is not limited in the embodiment of the present application.

[0042] In some embodiments, if the transfer device 30 is a satellite, the system further includes a ground station, which performs wireless communication with the transfer device 30 and the network device 20 respectively.

[0043] In the embodiment of the present application, if the network device 20 needs to send a signal to the terminal 10 , it first sends the signal to the transfer device 30 , and the transfer device 30 then forwards the received signal to the terminal 10 .

[0044] In some embodiments, the transfer device 30 includes two transfer modes, namely, a transparent transmission mode and a regeneration mode.

[0045] For example, if the transfer mode of the transfer device 30 is the transparent transmission mode, after the network device 20 sends a signal to the transfer device 30, the transfer device 30 converts the frequency of the signal and sends it to the terminal 10 without demodulating the signal.

[0046] For another example, if the transfer mode of the transfer device 30 is the regeneration mode, after the network device sends a signal to the transfer device 30, the transfer device 30 first demodulates the received signal, then re-encodes and modulates it to obtain a regenerated signal, and sends the regenerated signal to the terminal 10.

[0047] Figure 3 A flow chart of a channel determination method provided by an exemplary embodiment of the present application is shown, which is applied to Figure 1 or Figure 2 In the system shown, the method includes at least some of the following steps:

[0048] Step 301: The network device sends an uplink authorization configuration to the terminal, where the uplink authorization configuration is used to configure a logical channel for uplink transmission.

[0049] In an embodiment of the present application, the uplink grant configuration is logical channel grant information configured by a network device and is used to configure a logical channel for uplink transmission. The uplink resources included in the logical channel are referred to as uplink transmission. The resources included in the logical channel authorized by the uplink grant configuration are similar to the resources for uplink dynamic scheduling, and can also be understood as the resources included in the logical channel being periodically recurring uplink resources configured by the network device.

[0050] If the network device needs to schedule uplink resources for the terminal, it sends an uplink authorization configuration to the terminal, and configures a logical channel for uplink transmission for the terminal through the uplink authorization configuration.

[0051] In some embodiments, the network device may send multiple uplink grant configurations to the terminal, and each uplink grant configuration may configure a logical channel for uplink transmission.

[0052] Step 302: The terminal receives the uplink authorization configuration sent by the network device.

[0053] In an embodiment of the present application, the uplink authorization configuration is used to configure a logical channel for uplink transmission. After the terminal receives the uplink authorization configuration sent by the network device, it determines the logical channel for uplink transmission corresponding to the uplink authorization configuration.

[0054] Step 303: The terminal determines the logical channel corresponding to the uplink grant configuration based on the uplink grant configuration and the logical channel priority LCP restriction condition based on the HARQ retransmission status information. The HARQ retransmission status information indicates the status of the HARQ process.

[0055] In an embodiment of the present application, the terminal determines the logical channel configured by the network device according to the uplink authorization configuration, and when determining the logical channel for uplink transmission, the terminal determines it based on the LCP restriction condition of the HARQ retransmission status information so that the determined logical channel meets the LCP restriction condition.

[0056] In some embodiments, the HARQ retransmission state information is represented by HARQ retransmission state.

[0057] In an embodiment of the present application, the network device can be configured with up to 32 HARQ processes, and the status of each HARQ process is configured through HARQ retransmission status information.

[0058] Among them, the maximum number of HARQ processes configured by the network device is only an example. The maximum number of the maximum HARQ process can also be other values, which is not limited in the embodiments of the present application.

[0059] The first point to be explained is that the embodiment of the present application is only described by taking the interaction between the terminal and the network device as an example. In another embodiment, the terminal and the network device interact through the transfer device, and the interaction method is the same as the above. Figure 3 The systems shown are similar and will not be described again here.

[0060] The second point that needs to be explained is that the steps executed by the network device in the embodiment of the present application can independently form a new embodiment, and the steps executed by the terminal can also independently form a new embodiment.

[0061] According to the method provided in the embodiment of the present application, after the terminal determines the logical channel configured by the network device based on the received uplink authorization configuration, the terminal determines the logical channel that meets the requirements through the LCP restriction condition based on the HARQ state information. There is no need to use authorization parameters to restrict the logical channel, thereby ensuring the accuracy of the determined logical channel.

[0062] exist Figure 3 Based on the embodiment shown, the HARQ retransmission status information configured by the network device includes multiple states indicating the HARQ process. Each state is described below.

[0063] In an embodiment of the present application, the network device is configured with multiple HARQ processes, and each HARQ process has a corresponding state. The HARQ retransmission state information includes any of the following:

[0064] The first HARQ state indicates a state of the HARQ process in which the network device performs retransmission scheduling based on uplink data.

[0065] In some embodiments, the first HARQ state is represented by HARQ state A.

[0066] The length of drx-HARQ-RTT-TimerUL in HARQ state A is extended by the UE-gNB RTT. This means that the length of drx-HARQ-RTT-TimerUL in HARQ state A is extended by the delay from the terminal to the network device.

[0067] The second HARQ state indicates that the state of the HARQ process is that the network device does not perform retransmission scheduling based on uplink data.

[0068] In some embodiments, the second HARQ state is represented by HARQ state B or Legacy HARQ state.

[0069] The HARQ state B is indicated as drx-HARQ-RTT-TimerUL is not started, which means that the HARQ state B indicates that drx-HARQ-RTT-TimerUL is not started. The legacy HARQ state is indicated as Legacy behavior of drx-HARQ-RTT-TimerUL applies, which means that the legacy HARQ state indicates that drx-HARQ-RTT-TimerUL applies.

[0070] above Figure 3 In the illustrated embodiment, the terminal can determine a logical channel for uplink transmission. However, depending on whether the terminal is configured with HARQ retransmission status information and whether the logical channel is configured with an LCP restriction condition based on the HARQ retransmission status information, the logical channel determined by the terminal is different. The following describes the logical channel determined by the terminal in different cases:

[0071] The first type: When the terminal is configured with HARQ retransmission status information, the logical channel is configured with LCP restriction conditions based on the HARQ retransmission status information, and the logical channel is not configured with authorization parameters, the terminal determines the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction conditions based on the HARQ retransmission status information.

[0072] In an embodiment of the present application, the network device configures HARQ retransmission status information for the terminal, that is, the HARQ process of the terminal has a state indicated by the HARQ retransmission status information. At this time, if the terminal needs to determine the logical channel for uplink transmission, it is necessary to first consider the configuration of the logical information. If the logical channel is configured with an LCP restriction condition based on the HARQ retransmission status information, and the logical channel is not configured with an authorization parameter, the terminal determines the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction condition based on the HARQ retransmission status information, and uses the logical channel for uplink transmission.

[0073] In the method provided in the embodiment of the present application, if the terminal is configured with HARQ retransmission status information, and the logical channel configuration is based on the LCP restriction condition of the HARQ retransmission status information, and the authorization parameters are not configured, then the logical channel corresponding to the uplink authorization configuration and meeting the LCP restriction condition based on the HARQ retransmission status information can be directly determined as the logical channel for uplink transmission, without configuring the authorization parameters, which not only saves signaling overhead but also ensures the accuracy of the determined logical channel.

[0074] The second type: when the terminal is configured with HARQ retransmission status information, the logical channel is configured with LCP restriction conditions based on the HARQ retransmission status information, and the logical channel is configured with authorization parameters, the terminal determines the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction conditions based on the configured authorization parameters.

[0075] In an embodiment of the present application, the network device configures HARQ retransmission status information for the terminal, that is, the HARQ process of the terminal has a state indicated by the HARQ retransmission status information. At this time, if the terminal needs to determine the logical channel for uplink transmission, it is necessary to first consider the configuration of the logical information. If the logical channel is configured with an LCP restriction condition based on the HARQ retransmission status information, and the logical channel is also configured with an authorization parameter, the terminal determines the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction condition based on the configured authorization parameter, and uses the logical channel for uplink transmission.

[0076] That is, if the logical channel is configured with both LCP restriction conditions based on HARQ retransmission status information and LCP restriction conditions based on authorization parameters, when the terminal determines the logical channel, it only needs to consider whether the logical channel meets the LCP restriction conditions based on authorization parameters, without considering whether the logical channel meets the LCP restriction conditions based on HARQ retransmission status information.

[0077] According to the method provided in the embodiment of the present application, if the terminal is configured with HARQ retransmission status information, and the logical channel configuration is based on the LCP restriction condition of the HARQ retransmission status information, and the authorization parameters are configured, then the logical channel corresponding to the uplink authorization configuration and satisfying the LCP restriction condition based on the authorization parameters is directly determined as the logical channel for uplink transmission, and the logical channel satisfying the LCP restriction condition based on the authorization parameters is preferentially determined, thereby improving the reliability of uplink transmission of the terminal.

[0078] It should be noted that in the first and second cases of the embodiment of the present application, the terminal is configured with HARQ retransmission status information, and the network device configures the HARQ retransmission status information for the terminal, see Figure 4 , the method comprising:

[0079] Step 401: The network device sends HARQ configuration information to the terminal, where the HARQ configuration information is used to configure HARQ retransmission state information.

[0080] Step 402: The terminal receives HARQ configuration information sent by the network device.

[0081] In an embodiment of the present application, the network device configures HARQ retransmission status information by sending HARQ configuration information to the terminal. After receiving the HARQ configuration information, the terminal determines the status of the HARQ process configured by the network device through the HARQ retransmission status information.

[0082] In some embodiments, the HARQ configuration information is carried in RRC (Radio Resource Control) signaling.

[0083] In an embodiment of the present application, the network device sends RRC signaling including HARQ configuration information to the terminal. After the terminal receives the RRC signaling, the HARQ configuration information can be obtained from the RRC signaling, and then the HARQ retransmission status information corresponding to the HARQ configuration information is determined, and the status of the HARQ process configured by the network device for the terminal is determined.

[0084] The third type: when the terminal is not configured with HARQ retransmission status information and the logical channel configuration is based on the LCP restriction condition of the HARQ retransmission status information, the terminal determines the logical channel corresponding to the uplink authorization configuration and does not meet the LCP restriction condition based on the HARQ retransmission status information.

[0085] In an embodiment of the present application, the network device does not configure HARQ retransmission status information for the terminal, that is, the HARQ process of the terminal does not have a status indicated by the HARQ retransmission status information. At this time, if the terminal needs to determine the logical channel for uplink transmission, even if the logical channel is configured with an LCP restriction condition based on the HARQ retransmission status information, the terminal determines the logical channel that corresponds to the uplink authorization configuration and does not meet the LCP restriction condition based on the HARQ retransmission status information, and uses the logical channel for uplink transmission.

[0086] Alternatively, when the terminal is not configured with HARQ retransmission status information and the logical channel configuration is based on the LCP restriction condition of the HARQ retransmission status information, determine the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction condition based on the HARQ retransmission status information.

[0087] In an embodiment of the present application, the network device does not configure HARQ retransmission status information for the terminal, that is, the HARQ process of the terminal does not have a status indicated by the HARQ retransmission status information. At this time, if the terminal needs to determine the logical channel for uplink transmission, even if the logical channel is configured with an LCP restriction condition based on the HARQ retransmission status information, the terminal determines the logical channel that corresponds to the uplink authorization configuration and meets the LCP restriction condition based on the HARQ retransmission status information, and uses the logical channel for uplink transmission.

[0088] It should be noted that, in the third case mentioned above, if the terminal in the embodiment of the present application is not configured with HARQ retransmission status information, the logical information determined by the terminal may meet the LCP restriction conditions based on the HARQ retransmission status information, or may not meet the LCP restriction conditions based on the HARQ retransmission status information. That is, it can be understood that the logical channel for uplink transmission determined by the terminal does not need to meet the LCP restriction conditions based on the HARQ retransmission status information.

[0089] exist Figure 3 Based on the embodiment shown, when determining the logical channel, the terminal needs to consider other LCP restriction conditions, and the LCP restriction conditions also include at least one of the following:

[0090] (1) SCS (Sub-Carrier Spacing) list: The SCS list indicates the sub-carrier spacing allowed for transmission.

[0091] In an embodiment of the present application, if the terminal needs to determine a logical channel that meets the LCP restriction condition, the subcarrier spacing of the logical channel should belong to the SCS list.

[0092] (2) PUSCH (Physical Uplink Shared Channel) interval: The PUSCH interval corresponding to the uplink grant of the logical channel is less than or equal to the PUSCH interval.

[0093] In an embodiment of the present application, if the terminal needs to determine a logical channel that meets the LCP restriction condition, the PUSCH interval of the logical channel should belong to the PUSCH interval in the LCP restriction condition.

[0094] (3) The authorization type allowed by the logical channel, which includes at least one of configuration authorization type 1 and configuration authorization type 2.

[0095] In an embodiment of the present application, such as configured Grant Allowed (which can be interpreted as available configuration authorization), it can include configuration authorization type 1 and configuration authorization type 2 at the same time; configured Grant Type1 Allowed (which can be interpreted as available configuration authorization type 1); configured Grant Type2 Allowed (which can be interpreted as available configuration authorization type 2).

[0096] (4) Cell ID list: The cell ID list indicates the cells used for transmission.

[0097] In an embodiment of the present application, if the terminal needs to determine a logical channel that meets the LCP restriction condition, the logical channel should belong to the cell identifier list in the LCP restriction condition.

[0098] (5) Physical layer priority index, which indicates the dynamic authorization for transmission.

[0111] or,

[0112] When the terminal is not configured with HARQ retransmission status information and the logical channel configuration has an LCP restriction condition based on the HARQ retransmission status information, a logical channel is determined that corresponds to the uplink grant configuration and satisfies the LCP restriction condition based on the HARQ retransmission status information.

[0113] In some embodiments, the LCP constraint further includes at least one of the following:

[0114] SCS list, the SCS list indicates the subcarrier spacing allowed for transmission;

[0115] PUSCH interval: the PUSCH interval corresponding to the uplink grant of the logical channel is less than or equal to the PUSCH interval;

[0116] The authorization type allowed by the logical channel includes at least one of configuration authorization type 1 and configuration authorization type 2;

[0117] a cell identification list indicating cells to be used for transmission;
