[0114] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0115] The embodiments of the present disclosure 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), 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0116] In the disclosed embodiments, the continuous emergence of new internet applications such as augmented reality (AR), virtual reality (VR), and vehicle-to-vehicle (V2V) communication has placed higher demands on wireless communication technology, driving the continuous evolution of wireless communication technology to meet these application needs. Currently, cellular mobile communication technology is in the process of evolving into a new generation of technology. A key feature of this new generation of technology is the flexible configuration that supports multiple service types. Different service types have different requirements for wireless communication technology. For example, enhanced mobile broadband (eMBB) service types primarily require high bandwidth and high speed; ultra-reliable low-latency communications (URLLC) service types primarily require high reliability and low latency; and massive machine type communications (mMTC) service types primarily require a large number of connections. Therefore, the next generation of wireless communication systems requires flexible and configurable designs to support the transmission of multiple service types.
[0117] Satellite communications are considered a key aspect of future wireless communication technology. Satellite communications refer to communications conducted by ground-based radio communication equipment using satellites as relays. Satellite communication systems consist of satellite and ground components. Satellite communications are characterized by a wide range, enabling communication between any two points within the range of the satellite's radio waves, and high reliability, as well as being less susceptible to land-based disasters.
[0118] Satellite communications, as a supplement to terrestrial communication systems, offer the following advantages: 1. Extended coverage: Satellite communications can be used to address areas where cellular communication systems are inaccessible or costly, such as oceans, deserts, and remote mountainous areas. 2. Emergency communications: In extreme situations such as disasters (e.g., earthquakes) where cellular communication infrastructure is unavailable, satellite communications can quickly establish a connection. 3. Industry applications: For example, satellite communications can be used to reduce latency in long-distance, delay-sensitive services.
[0119] It is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the intelligent connection of all things.
[0120] In some embodiments, in the case of satellite communication, due to the long signal transmission distance between the transmitter and the receiver, data transmission takes a long time. For transmission with uplink and downlink relationship, an offset parameter (Koffset) can be introduced to compensate for the transmission delay. offset It can be applied in various scenarios, such as physical uplink shared channel (PUSCH) transmission scheduled by downlink control information (DCI), transmission of HARQ feedback information, and transmission of media access control (MAC) control element (CE).
[0121] In some embodiments, FIG1B is a schematic diagram illustrating HARQ blocking in a terminal in an NTN scenario according to an embodiment of the present disclosure. As shown in FIG1B , the terminal is configured with a HARQ process (HRAQ process). Due to the large latency in satellite communication systems, HARQ blocking may occur in terminals (such as IoT devices), thereby reducing the terminal's transmission rate. Optionally, in other scenarios with large latency, the terminal may also experience HARQ blocking, thereby reducing the terminal's transmission rate. Therefore, the various embodiments of the present disclosure can be applied to other scenarios with large latency as appropriate.
[0122] 1. HARQ state of HARQ process
[0123] In the disclosed embodiments, for IoT devices, the HARQ state of the configured HARQ process can be determined through a semi-static configuration from a network device. Alternatively, the HARQ state of the configured HARQ process can be determined by receiving a DCI indication, which can override the HARQ state of the HARQ process in the semi-static configuration.
[0124] In the embodiments of the present disclosure, “overwrite” can be interchanged with “rewrite”, “reconfigure”, “change”, “modify”, “adjust”, “update” and the like.
[0125] In the embodiments of the present disclosure, “HARQ state” may be interchangeable with terms such as “HARQ feedback state” and “HARQ response state”.
[0126] In some embodiments, to achieve flexible configuration and improve system performance, the HARQ state of the HARQ process may be indicated or overridden via HARQ feedback resource information. If the HARQ state of the HARQ process is indicated via DCI, this is referred to as DCI-based indication; if the HARQ state of the HARQ process is overridden via DCI, this is referred to as DCI-based overriding.
[0127] In some embodiments, HARQ feedback resource information is carried in a HARQ feedback resource field in the DCI. The HARQ feedback resource may be an "ACK / NACK resource field," a "HARQ ACK resource field," or the like. The HARQ feedback resource field may be an "ACK NACK resource field," a "HARQ ACK resource field," or the like.
[0128] For example, Table 1 shows a HARQ feedback resource set. The HARQ feedback resource set includes 16 HARQ states, each of which corresponds to an allocated subcarrier and a time domain offset k0 value. The allocated subcarrier and time domain offset k0 are used to determine the resources used by the HARQ process when transmitting HARQ feedback (also referred to as HARQ feedback resources). When indicating or overwriting a HARQ state of a HARQ process through DCI, the HARQ feedback resource field in the DCI is used to indicate the subcarrier number and time domain offset k0 corresponding to the HARQ state allocated for the HARQ process.
[0129] As shown in Table 1 below, the subcarrier number that can be allocated in the frequency domain can be a value from the set {0, 1, 2, 3}, and the time domain offset k0 can be a value from the set {13, 15, 17, 18}. The ACK / NACK resource field in the DCI is 4 bits, of which 2 bits are used to indicate the subcarrier number and 2 bits are used to indicate the time domain offset k0.
[0130] Table 1
[0131] 2. HARQ Disabling
[0132] In the embodiment of the present disclosure, in order to avoid the problem of HARQ blocking in the NTN scenario and thus reduce the performance of the system, the HARQ disabling operation is introduced. That is, for a certain HARQ process, if HARQ disabling is configured, then the terminal does not feedback HARQ information for the downlink transmission of the HARQ process.
[0133] In the embodiments of the present disclosure, “disable” can be interchanged with terms such as “fail” and “disable”.
[0134] In some embodiments, for a certain HRAQ process, if HARQ is configured to be disabled, there is no need to allocate corresponding resources for the HARQ.
[0135] 3. HARQ enabling
[0136] In the embodiment of the present disclosure, for a certain HARQ process, if HARQ enable is configured, then the terminal feeds back HARQ information for downlink transmission of the HARQ process.
[0137] In the embodiments of the present disclosure, “enable” can be interchanged with terms such as “valid” and “available”.
[0138] In some embodiments, for a certain HRAQ process, if HARQ is enabled, corresponding resources are allocated to the HARQ. In this case, the subcarrier number and the time domain offset k0 are indicated in the DCI.
[0139] Therefore, how to indicate HARQ disabling or enabling through DCI needs to be clarified.
[0140] Figure 2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a communication method, and the method includes steps S210 to S270.
[0141] Step S210: The terminal sends first capability information.
[0142] In some embodiments, the network device receives first capability information.
[0143] In some embodiments, the first capability information is used to indicate the terminal's support capability for HARQ disabling indicated through DCI.
[0144] In some embodiments, the first capability information is used to indicate whether the terminal supports indicating HARQ disabling via DCI. Exemplarily, the first capability information is a first value, indicating that the terminal supports indicating HARQ disabling via DCI; the first capability information is a second value, indicating that the terminal does not support indicating HARQ disabling via DCI.
[0145] In some embodiments, the first capability information may also be referred to as, for example, terminal capability information, UE capability information, etc.
[0146] In some embodiments, step S210 is omitted, the terminal is configured to support indicating HARQ disabling through DCI, or the terminal supports indicating HARQ disabling through DCI by default or by default.
[0147] Step S220: The network device sends fourth information.
[0148] In some embodiments, the terminal receives fourth information.
[0149] In some embodiments, the network device determines, based on the first capability information, that the terminal is configured to support indicating HARQ disabling through DCI.
[0150] In some embodiments, the network device determines, based on the first capability information, that the terminal is configured to not support indicating HARQ disabling through DCI.
[0151] In some embodiments, steps S210 and S220 are omitted, and the terminal is configured to support HARQ disabling via DCI indication, or the terminal supports HARQ disabling via DCI indication by default or by default. At this time, the network device determines that the terminal supports HARQ disabling via DCI indication, or the network device determines by default or by default that the terminal supports HARQ disabling via DCI indication.
[0152] Step S230: The network device sends DCI.
[0153] In some embodiments, the terminal receives DCI.
[0154] In some embodiments, DCI may be signaling sent to one or more terminals.
[0155] In some embodiments, the DCI may be terminal-specific signaling.
[0156] In some embodiments, the DCI is used to schedule at least one downlink transmission. The at least one downlink transmission occupies at least one HARQ process, ie, a first HARQ process.
[0157] In some embodiments, the DCI is used to indicate a HARQ state corresponding to the first HARQ process. In one embodiment, the HARQ state includes HARQ disabled or HARQ enabled. In one embodiment, the DCI is used to indicate that the HARQ state corresponding to the first HARQ process is HARQ disabled. In one embodiment, the DCI is used to indicate that the HARQ state corresponding to the first HARQ process is HARQ enabled.
[0158] In some embodiments, the DCI is used to indicate the HARQ state corresponding to the first HARQ process through DCI based indication.
[0159] In some embodiments, the DCI is used to indicate the HARQ state corresponding to the first HARQ process through DCI based overriding.
[0160] In some embodiments, the DCI includes first information, the first information being used to indicate that the HARQ state corresponding to the first HARQ process is HARQ disabled. In one embodiment, the first information is used to indicate that the HARQ state corresponding to the first HARQ process is configured as HARQ disabled. In one embodiment, the first information is used to indicate that the first HARQ process is configured as HARQ disabled.
[0161] In some embodiments, the first information is carried in a HARQ feedback resource field in the DCI. Exemplarily, the HARQ feedback resource field may be an "ACK / NACK resource" field, a "HARQ ACK resource" field, a "HARQ status indication" field, a "HARQ feedback status indication" field, or the like.
[0162] In some embodiments, the first information may be a bit having a first value. In one embodiment, the first value is predefined or preconfigured.
[0163] In some embodiments, the first information may be determined from a HARQ feedback resource set.
[0164] In some embodiments, the HARQ feedback resource set includes first information and at least one second information, wherein the first information corresponds to HARQ disabling and the second information corresponds to HARQ enabling.
[0165] In some embodiments, the second information is used to indicate HARQ feedback parameters, such as the subcarrier number and time domain offset k0. In one embodiment, the HARQ feedback parameters are used to indicate the resources used when transmitting HARQ feedback corresponding to the HARQ process. In one embodiment, the resources used when transmitting HARQ feedback corresponding to the HARQ process can also be described as HARQ feedback resources. In this case, the HARQ resource parameters are used to indicate the HARQ feedback resources corresponding to the HARQ process.
[0166] In some embodiments, the HARQ feedback resource set may be the same for DCI used for DCI based indication or DCI based overriding. For example, Table 2 shows a HARQ feedback resource set, which includes 16 HARQ states, of which 15 HARQ states are used to indicate HARQ enablement and 1 HARQ state is used to indicate HARQ disablement. The above 15 HARQ states (i.e., HARQ enablement) correspond one to one to an allocated subcarrier and a value of a time domain offset k0, and the allocated subcarrier and time domain offset k0 are used to determine the HARQ feedback resource corresponding to the HARQ process.
[0167] For example, referring to Table 2 below, for HARQ enabling, the second information may be one of the HARQ feedback resource index set (i.e., the first column in Table 2) {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}. Among them, the number of subcarriers that can be allocated in the frequency domain may be a value in the set {0, 1, 2, 3}, and the value of the time domain offset k0 may be a value in the set {13, 15, 17, 18}. The ACK / NACK resource field in the DCI is 4 bits, of which 2 bits are used to indicate the subcarrier number and 2 bits are used to indicate the time domain offset k0. For HARQ disabling, the first information may be the HARQ feedback resource set index {15}.
[0168] Table 2
[0169] In some embodiments, the HARQ feedback resource set may be different for DCI used for DCI based indication or DCI based overriding. For example, Table 2 above shows a HARQ feedback resource set corresponding to DCI based indication (recorded as the first HARQ feedback resource set), and Table 3 below shows a HARQ feedback resource set corresponding to DCI based overriding (recorded as the second HARQ feedback resource set). Each HARQ feedback resource set includes 16 HARQ states, of which 15 HARQ states are used to indicate HARQ enablement and 1 HARQ state is used to indicate HARQ disablement. Among them, the 15 HARQ states (i.e., HARQ enablement) correspond one-to-one to an allocated subcarrier and a value of a time domain offset k0, and the allocated subcarrier and time domain offset k0 are used to determine the HARQ feedback resource corresponding to the HARQ process.
[0170] Furthermore, in Table 2, for HARQ enabling, the second information may be one of the HARQ feedback resource index (i.e., the first column in Table 2) set {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}. For HARQ disabling, the first information may be one of the HARQ feedback resource set index {15}. In Table 3, for HARQ enabling, the second information may be one of the HARQ feedback resource index (i.e., the first column in Table 3) set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}. The number of subcarriers that can be allocated in the frequency domain may be a value in the set {0, 1, 2, 3}, and the value of the time domain offset k0 may be a value in the set {13, 15, 17, 18}. The ACK / NACK resource field in the DCI is 4 bits, of which 2 bits are used to indicate the subcarrier number and 2 bits are used to indicate the time domain offset k0. For HARQ enablement and disablement, the first information can be the HARQ feedback resource set index {0}.

In one embodiment, the third information is used to indicate that the first HARQ process is configured as HARQ enabled.

[0189] Step S260: The terminal determines the HARQ feedback resource corresponding to the first HARQ process.
[0190] In some embodiments, the terminal determines HARQ resource parameters corresponding to the first HARQ process, such as the subcarrier number and the time domain offset k0, based on the third information, and then determines the corresponding HARQ feedback resource based on the HARQ resource parameters.
