Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a transmission method and apparatus. Background Technology

[0002] Time Division Duplex (TDD) is a commonly used duplexing technology in traditional terrestrial networks. When using TDD for transmission, a periodic transmission mode is typically defined, allocating a portion of the periodic time domain resources for downlink transmission, another portion for uplink transmission, and a portion for guard intervals or flexible resources. In non-terrestrial network (NTN) communication systems, TDD communication suffers from significant transmission delays due to the distance between satellites or spacecraft and the ground. To address these delays, a large timing advance (TA) is typically used for uplink transmission. Furthermore, to avoid conflicts between uplink and downlink transmissions, a large guard interval may be required between downlink and uplink time domain resources to mitigate the impact of the large TA. Thus, multiple discontinuous transmission times may exist when using TDD in NTN communication systems. However, current transmission resource allocation and scheduling are typically designed for continuous transmission; applying this to TDD transmission in NTN communication systems may lead to resource conflicts. Summary of the Invention

Detailed Implementation

[0013] When using TDD for transmission in an NTN communication system, a large guard interval may be required between downlink and uplink time domain resources to avoid conflicts between uplink and downlink transmissions, in order to cope with the impact of large transmission times (TAs). In this case, the time available for downlink or uplink transmission in the transmission resources may only account for a small portion. Thus, the time available for data transmission within a certain period is significantly reduced compared to Frequency Division Duplex (FDD), and there may be multiple discontinuous transmission times. Furthermore, when using repetitive transmissions to improve coverage performance, a downlink or uplink channel may not be completed within a continuous downlink or uplink time. Therefore, current transmission resource allocation and scheduling methods may no longer be applicable (e.g., resource conflicts may occur). For this scenario of limited and discontinuous transmission time, this application provides an embodiment of a transmission resource allocation and scheduling method suitable for NTN TDD to reduce or avoid resource conflicts.

[0016] Figure 1 This is a schematic diagram of an embodiment of the NTN communication system of this application. Figure 1As shown, the NTN communication system includes satellites, user equipment (UEs), and access network equipment (such as base stations and gateways). The link between the UE and the satellite is a service link, and the link between the access network equipment and the satellite is a feeder link.

[0017] To facilitate understanding of the technical solutions provided in the embodiments of this application, some concepts and terms involved in the embodiments of this application will be explained below. It is worth noting that the content within parentheses in this application is for illustrative purposes and may or may not be part of the technical features.

[0018] Periodic pattern: This may also refer to transmission configuration, transmission mode, periodic configuration, etc. For example, the length or period of a transmission pattern is T. Each periodic pattern may contain one or more uplink times, one or more downlink times, and one or more guard intervals. For example... Figure 2 The cycle pattern shown includes three protection intervals, one uplink time, and one downlink time.

[0019] Uplink time: This may also refer to uplink service time, uplink activation time, uplink configuration time, uplink duration, uplink mode, etc. In TDD mode, uplink and downlink are time-divided resources, meaning that uplink transmission takes place for a portion of the time, downlink transmission takes place for a portion of the time, and additional time is used as a guard interval / protection time or flexible / special time. Uplink time refers to the time used for uplink transmission as defined by the standard protocol or configured by the network (in periodic mode). Here, time may also refer to time-domain resources. For example, uplink time may refer to uplink subframes, available uplink subframes, or Narrowband Internet of Things (NB-IoT) uplink subframes, etc.

[0020] Downlink time: This may also refer to downlink service time, downlink activation time, downlink configuration time, downlink duration, downlink mode, etc. Downlink time refers to the time used for downlink transmission as defined by the standard protocol or configured by the network (in periodic mode). Time here may also refer to time-domain resources. For example, downlink time may refer to downlink subframes, available downlink subframes, or NB-IoT downlink subframes, etc.

[0021] Guard interval: This may also refer to guard time, non-service time, inactive time, flexible time, special time, offset time (between uplink and downlink times), non-uplink / downlink time, time other than uplink and downlink times, etc. It may be defined by standard protocols or configured by the network. Here, time or interval may also refer to time-domain resources. For example, a guard interval may refer to a subframe not configured as a downlink or uplink subframe, or consecutive subframes between downlink and uplink subframes, etc. It is worth noting that a guard interval may refer to at least one of the following four: The interval between the downtime and the uptime (in the current / next / previous cycle pattern); The interval between the uptime and the downtime (in the current / next / previous cycle pattern); The interval between the downtrend time and the end or start time of the cycle pattern; The interval between the uplink time and the end or start time of the cycle pattern; Non-uplink time: refers to time other than uplink time, which may include downlink time and protection interval; Non-downlink time: refers to time other than downlink time, which may include uplink time and protection interval.

[0022] Overlap: It may also refer to overlapping, conflict, collision, coincidence, etc., indicating that two resources partially or completely overlap.

[0023] Uplink transmission: This may refer to the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH), or uplink reference signals (such as Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), Phase-tracking Reference Signal (PTRS), etc.). It may also refer to the timing of uplink transmission, such as the Random Access Response (RACH) occasion or the Configuration Grant (CG) occasion.

[0024] Downlink transmission: This may refer to the Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Broadcast Channel (PBCH), or downlink reference signals (such as Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Synchronization Signal Block (SSB), Channel State Information-Reference Signal (CSI-RS), DMRS, PTRS, Channel Request Signal (CRS), Narrowband Reference Signal (NRS), etc.). It may also refer to the (detection) timing of downlink transmission, such as the search space or the Semi-Persistent Scheduling (SPS) occasion.

[0025] The units or units of time mentioned above may be superframes, frames, subframes, time slots, symbols, samples, etc., or absolute time such as milliseconds. When time resources used for transmission or mapping overlap with non-transmission time, it may be necessary to specify the UE's behavior. For example, when a subframe originally used for PDSCH transmission or mapping overlaps with non-downlink time, it may be necessary to specify the UE's handling method, such as delaying or canceling PDSCH transmissions that overlap with non-downlink time. Alternatively, the above overlap situation can be avoided, for example, by introducing additional scheduling delays to prevent PDSCH transmissions from falling into non-downlink time, or by limiting the length of PDSCH to prevent PDSCH from extending into non-downlink time.

[0026] The technical solutions provided in this application may be applied to various networks, including but not limited to New Radio (NR), NB-IoT, enhanced Machine-Type Communication (eMTC), or 6th generation (6G). thGeneration (6G) networks, etc. The various channels or signals described in the embodiments of this application may also refer to channels in other networks that have the same function but different names or formats. For example, PDSCH may also refer to Narrow Band Physical Downlink Shared Channel (NPDSCH), etc. PDCCH may also refer to Narrow Band Physical Downlink Control Channel (NPDCCH), Machine-type Communication Physical Downlink Control Channel (MPDCCH), etc. PUSCH may also refer to Narrow Band Physical Uplink Shared Channel (NPUSCH), etc. PRACH may also refer to Narrow Band Physical Random Access Channel (NPRACH), etc. PBCH may also refer to Narrow Band Physical Broadcast Channel (NPBCH), etc. Master information block (MIB) may also refer to Master information block Narrow Band (MIB-NB), etc. System information block x (SIBx) (x>=1) may also refer to narrowband system information block x (SIBx-NB), etc. Primary synchronization signal (PSS) may also refer to narrowband primary synchronization signal (NPSS), etc. Secondary synchronization signal (SSS) may also refer to narrowband secondary synchronization signal (NSSS), etc.

[0027] In the embodiments of this application, the configuration or indication information on the network side may be indicated through at least one of the following signaling: MIB, PBCH, SIB1, SIBx (x>=1), Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE), MAC header / subheader, Downlink Control Information (DCI) signaling, etc. Specific indication methods may include, but are not limited to: defining a new bit field to indicate, reusing an existing bit field to indicate, reusing one or more states of an existing bit field to indicate, introducing a new information element (IE) to indicate (such as enumerating multiple candidate values, indicating one from multiple candidate values, or indicating a specific value), introducing a new MAC CE and indicating through the MAC CE, introducing a new MAC subheader and indicating through the code point of the Logical Channel Identification (LCID), and using relevant information of the scrambling code to indicate (such as Radio Network Temporary Identity (RNTI), code sequence, root of the generation code, seed of the generation code, etc.).

[0028] For the functions or signaling mentioned in the embodiments of this application, enable signaling may be introduced to control whether the function or signaling is enabled, used, activated, or present. For example, if an existing bit field is reused to indicate a certain information, the UE will only perform the corresponding behavior according to the function or signaling after the enable signaling enables the corresponding function or signaling.

[0029] The wireless communication device in this application embodiment can be a terminal (also called a UE), such as a mobile phone, tablet computer, wearable device, aircraft, vehicle-mounted device, etc., without specific limitations. The wireless communication node can be a network-side device (can be called a network side, network node, etc.), such as an access network device or a core network device (can also be called a core network node, core network function, or core network element, etc.). The access network device can be a base station, and the core network device can be a Mobility Management Entity (MME), Access and Mobility Management Function (AMF), etc., without specific limitations.

[0030] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] Figure 3 This is a flowchart illustrating a transmission method according to an embodiment of this application. The transmission method can be executed by a wireless communication device; in other words, the transmission method can be executed by software or hardware installed on the wireless communication device. The transmission method includes the following steps.

[0032] S302: The wireless communication device determines the transmission resources, which include the resources for transmission between the wireless communication device and the wireless communication node.

[0033] S304: Wireless communication devices transmit data according to transmission resources.

[0034] In NTN communication systems using TDD for communication, the wireless communication device can determine transmission resources, including resources for transmission between the wireless communication device and the wireless communication node, and then transmit with the wireless communication node according to the determined transmission resources. The transmission resources determined by the wireless communication device can be time-domain resources related to uplink transmission and / or time-domain resources related to downlink transmission. When transmitting with the wireless communication node according to the determined transmission resources, resource conflicts can be reduced or avoided, such as reducing or avoiding overlap between uplink and non-uplink time and / or downlink and non-downlink time.

[0035] As previously mentioned, the transmission resources determined by the wireless communication device may be time-domain resources related to uplink transmission and / or time-domain resources related to downlink transmission. In some embodiments, the transmission resources determined by the wireless communication device may specifically include at least one of the following (a) to (viii): (a) Protection interval.

[0036] TDD is a commonly used duplex technology in traditional terrestrial networks. In TDD, a periodic transmission pattern is typically defined, allocating a portion of the periodic time-domain resources as downlink transmission resources, another portion as uplink transmission resources, and a portion as guard intervals or flexible resources. Based on the configured periodic pattern, the UE can determine when to perform downlink transmission and when to perform uplink transmission within each period.

[0037] In NTN communication systems, due to the great distance between satellites or spacecraft and the ground, there is a significant transmission delay between the UE and the network. To cope with this large transmission delay, the UE uses a large timing advance (TA) during uplink transmission. This allows uplink and downlink timing to be aligned at an uplink time synchronization reference point (such as a satellite, ground gateway, a point on the feeder link, or a point on the service link). If TDD technology is used in an NTN system, a large guard interval may be needed between downlink time (or downlink time domain resources) and uplink time (or uplink time domain resources) to avoid conflicts between uplink and downlink transmissions caused by the large TA. However, a large guard interval may lead to greater latency, lower throughput, or weaker scheduling flexibility. Furthermore, the size of the TA in NTN may vary depending on the satellite's orbital altitude or elevation angle. For example, for a satellite at an altitude of 1200km, when the UE is at the nadir (i.e., the elevation angle between the user and the satellite is 90°), the maximum round-trip latency from the UE to the network node is approximately 16ms, meaning a 16ms guard interval is sufficient. However, when the elevation angle between the user and the satellite is 10°, the maximum round-trip latency from the UE to the network node can reach 42ms, requiring a 42ms guard interval to avoid uplink and downlink conflicts. Therefore, a flexible / dynamic guard interval may need to be introduced to address different scenarios.

[0038] (ii) Time-domain resources of the first transmission.

[0039] As mentioned earlier, when using TDD mode in an NTN communication system, there may be a large guard interval to avoid uplink and downlink conflicts. Therefore, the available time for downlink transmission is relatively short in each cycle mode, and within a certain period, there may only be multiple discontinuous short segments of downlink transmission time. In this case, if the duration of downlink transmission is relatively long (e.g., during repeated transmissions), or the start time of downlink transmission is relatively late, or the periodic downlink transmission does not match the downlink time cycle, then the (original) downlink transmission may overlap with non-downlink time. Since the network cannot send downlink transmissions or the UE cannot receive downlink transmissions during non-downlink time, it is necessary to define additional UE or network-side behaviors to clarify how to handle downlink transmissions overlapping with non-downlink time.

[0040] Similarly, for uplink transmission, there may be an overlap between (original) uplink transmission and non-uplink time. Since the UE cannot send uplink transmissions during non-uplink time, it is also necessary to define the behavior of the UE or network side to clarify how to handle uplink transmissions that overlap with non-uplink time.

[0041] The aforementioned first transmission includes transmissions overlapping with non-transmission times. This first transmission can be an uplink transmission and / or a downlink transmission. The non-transmission time can be a non-uplink time and / or a non-downlink time. The overlap can be partial or complete. The transmissions overlapping with non-transmission times include at least uplink transmissions overlapping with non-uplink times and / or downlink transmissions overlapping with non-downlink times. Downlink transmissions may refer to DCI-scheduled downlink transmissions, higher-layer triggered / scheduled downlink transmissions, or pre-configured downlink transmissions. Uplink transmissions may refer to DCI-scheduled uplink transmissions, higher-layer triggered / scheduled uplink transmissions, or pre-configured uplink transmissions.

[0042] (iii) Time-domain resources of the second transmission.

[0043] The second transmission here can be an uplink and / or downlink transmission following the first downlink transmission. A corresponding scenario is that the wireless communication device might receive the first downlink transmission and then determine the transmission / reception time of the second transmission (based on the reception time of the first downlink transmission). In this scenario, there may be a delay or offset between the first downlink transmission and the second transmission, such as scheduling delay. In NTN TDD mode, due to the large guard interval, the second transmission determined by the wireless communication device based on the traditional scheduling delay after receiving the first downlink transmission may overlap with non-uplink or non-downlink times. Therefore, additional delay can be introduced to avoid or mitigate overlap.

[0044] In some implementations, possible combinations of the first downlink transmission and the second transmission are shown in Table 1.

[0045] Table 1

[0046] (iv) Time window.

[0047] As mentioned earlier, the large guard interval in NTN TDD results in only a short downlink time within a single cycle pattern. In traditional / FDD / terrestrial networks, some time windows may have fixed lengths (such as the System Message Time Window (SIwindow). In this case, the time available for downlink transmission within the time window may be significantly reduced. System Information (SI) or System Information Block (SIB) may not be able to complete transmission within the SI window. To address this issue, adjustments to the time window are needed, such as modifying its definition, start time, and length.

[0048] In some implementations, the time window may include, but is not limited to, at least one of the following: System Information (SI) time window; Random Access Response (RAR) time window; MsgB time window; Discontinuous Reception (DRX) time window; Discontinuous Transmission (DTX) time window; Paging time window, etc.

[0049] (v) Timer.

[0050] As mentioned earlier, the large guard interval in NTN TDD results in only a very short downlink time within a single cycle. In traditional / FDD / terrestrial networks, some timers may have fixed durations. In this case, the time available for downlink transmission within the timer may be significantly reduced. To address this issue, adjustments to the timers are necessary, such as modifying the timer definition, start / restart time, and duration.

[0051] In some implementations, the timer may include, but is not limited to, at least one of the following: Contention resolution timer; Hybrid Automatic Repeat Request Round Trip Time (HARQ RTT) timer (Up Link / Down Link). Reassembly timer / t-Reordering timer; The scheduling request disables the sr-Prohibit timer; Discard timer; Configure the grant timer; Pre-configure uplink resource response timer pur-Response Window Timer.

[0052] (vi) Paging resources (such as paging timing, paging frames or paging superframes).

[0053] In current systems, wireless communication devices, taking the UE as an example, detect paging messages or their scheduling information on paging resources, such as the PDCCH corresponding to the Paging Radio Network Temporary Identity (P-RNTI). Paging resources may include paging frames (PF), paging occasions (PO), paging hyperframes (PH), paging narrowbands (PNB), paging carriers, and paging time windows (PTW). Paging resources are typically determined based on the UE ID (such as Temporary Mobile Subscriber Identity (TMSI), International Mobile Subscriber Identity (IMSI), or TMSI / IMST modX, where X may be an integer). For example, for NB-IoT systems, the paging frame is determined according to the following formula: SFN mod T= (T div N)*(UE_ID mod N) Where T is the discontinuous reception period or paging period, N=min(T,nB), and nB is a parameter configured on the network side (e.g., 4T, 2T, T, T / 2, T / 4, T / 8, T / 16, T / 32). The index of the paging timing within the paging frame is determined according to the following formula: i_s = floor(UE_ID / N) mod Ns Where Ns = max(1, nB / T).

[0054] According to the above mechanism, the paging timing for each UE is automatically determined by the UE ID, and the paging timings for different UEs can be evenly distributed over time. It is not possible to flexibly configure paging timings to concentrate them within a specific time period. Therefore, using traditional paging timing determination methods, there may be overlaps between paging timings and non-downlink times. Therefore, a new method for determining paging timing is needed to reduce or avoid overlaps between paging timings and non-downlink times.

[0055] (vii) Random access timing (also known as random access resources).

[0056] Similar to the paging resources mentioned above, when determining random access timing using traditional methods, there may be overlap between random access timing and non-downlink timing. Therefore, a new method for determining random access timing is needed to reduce or avoid this overlap.

[0057] (viii) Resources for transmitting warning information.

[0058] In NTN communication systems, satellites, being far from the ground, offer wide coverage and are unaffected by ground-based disasters, making them ideal for broadcasting warning information such as earthquakes and tsunamis. However, current NB-IoT systems do not support warning indications. Therefore, to support warning indications in IoT-NTN, additional warning information and corresponding signaling are required. Furthermore, if warning information is introduced, corresponding UE behaviors need to be defined to handle resource conflicts between warning signaling and other signaling, clarifying the UE's processing methods, such as determining the transmission resources for warning information, to reduce or avoid resource conflicts between warning signaling and other signaling.

[0059] The following will use some more specific implementation examples to illustrate how to determine the above-mentioned transmission resources.

[0060] Example 1: How a wireless communication device determines a guard interval when the transmission resources include a guard interval.

[0061] In some implementations, the wireless communication device determines the protection interval, which may include: The protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node.

[0062] The state of the wireless communication device may include at least one of the following: Idle state or initial access; Connected state.

[0063] The signaling of a wireless communication node may include at least one of the following: The first signaling is used to indicate the length of the first protection interval; The second signaling is used to indicate the length of the second protection interval; The third signaling is used to indicate whether the first signaling is enabled or used (or to indicate whether the first signaling is enabled or used, or to indicate whether the first signaling is disabled or not used, or whether the first protection interval (dynamic) configuration is enabled); The fourth signaling is used to indicate whether the second signaling is enabled or used (or to indicate whether the second signaling is enabled or used, or to indicate whether the second signaling is disabled or not used, or whether the second protection interval (dynamic) configuration is enabled); The fifth signaling is used to indicate the first differential protection interval; The sixth signaling is used to indicate whether the fifth signaling is enabled or used (or to indicate whether the fifth signaling is enabled or used, or to indicate whether the fifth signaling is disabled or not used, or whether the first differential protection interval (dynamic) configuration is enabled).

[0064] It should be noted that in practical applications, wireless communication devices may not receive all of the above six signaling messages. That is, wireless communication nodes may send some or all of the above six signaling messages to wireless communication devices, or may not send the above six signaling messages to wireless communication devices. When determining the protection interval, wireless communication devices can determine the protection interval based on the reception status of the signaling messages and / or the indication of the received signaling messages.

[0065] When a wireless communication device determines a protection interval based on at least one of the above six signaling schemes, it shall include at least the following schemes: Option 1-1: When the signaling of the wireless communication node includes the first signaling, the protection interval is determined based on the state of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) the first protection interval indicated by the first signaling is determined as the protection interval; In idle state or initial access situation, the protection interval is determined to be the default protection interval; In the connected state, the first protection interval indicated by the first signaling is determined as the protection interval.

[0066] In Scheme 1-1, the wireless communication node can directly configure the protection interval through the first signaling, and the wireless communication device can determine the protection interval by combining the first signaling and / or its own state (idle state, initial access, or connected state).

[0067] The first protection interval can be a single time interval or multiple time intervals; that is, a wireless communication node can configure one or more time intervals through a single signaling command. When the first protection interval is a single time interval, this single time interval can be defined as the protection interval. When the first protection interval is multiple time intervals, the protection interval can be determined jointly by these multiple time intervals. Similarly, the second protection interval or the first differential protection interval can also be a single time interval or multiple time intervals.

[0068] In some implementations, the protection interval (e.g., information indicated in the first, second, or fifth signaling) may include at least one of the following: The protection interval or offset between downlink and uplink times, such as the protection interval or offset between downlink and uplink times in the same cycle pattern; The interval or offset between the end time of the downlink time and the start time of the uplink time, such as the interval or offset between the end time of the downlink time and the start time of the uplink time in the same periodic pattern; The protection interval or offset between uplink and downlink times, such as the protection interval or offset between uplink and downlink times in the same cycle pattern; The interval or offset between the end time of the uplink time and the start time of the downlink time, such as the interval or offset between the end time of the uplink time and the start time of the downlink time in the same periodic pattern; The interval or offset between the start time of the downlink time and the start time of the uplink time, such as the interval or offset between the start time of the downlink time and the start time of the uplink time in the same periodic pattern; The interval or offset between the end time of the downlink time and the end time of the uplink time, for example, the interval or offset between the end time of the downlink time and the end time of the uplink time in the same periodic pattern.

[0069] The first signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI signaling, without specific limitations. When the first signaling is SIB, i.e., when the protection interval is configured via SIB, its information update (i.e., a change in the protection interval configuration) may not affect the modification / update identifier of the SI / SIB.

[0070] Optionally, in some implementations, if the wireless communication device does not receive the first signaling, i.e., the wireless communication node has not configured a protection interval, the wireless communication device can determine the protection interval as the default protection interval, which may be predefined by the standard.

[0071] Option 1-2: When the signaling of the wireless communication node includes first signaling and third signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) when the third signaling is used to indicate enable or use the first signaling (the first signaling has been received), the first protection interval indicated by the first signaling is determined as the protection interval; (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) In the case where the third signaling is used to indicate that the first signaling is not enabled or not used, or the third signaling is not received (regardless of whether the first signaling is received), the protection interval is determined to be the default protection interval, which may be predefined by the standard. In idle state or initial access situation, the protection interval is determined to be the default protection interval; In the connected state, if the third signaling is used to indicate enable or use of the first signaling, then the first protection interval indicated by the first signaling is determined as the protection interval; In the connected state, if the third signaling is used to indicate that the first signaling is not enabled or not used, or if the third signaling is not received, the protection interval is determined to be the default protection interval.

[0072] In schemes 1-2, wireless communication nodes can configure the protection interval through the first signaling and the third signaling. Wireless communication devices can determine the protection interval based on the first signaling, the third signaling, and / or their own state (idle state, initial access state, or connected state). The first signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI, and the third signaling can be MIB, PBCH, SIB, or RRC.

[0073] Scheme 1-3: When the signaling of the wireless communication node includes a first signaling and a second signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no second signaling is received (but the first signaling has been received), the first protection interval indicated by the first signaling is determined as the protection interval; (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving a second signaling (regardless of whether the first signaling is received), the second protection interval indicated by the second signaling is determined as the protection interval; (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no first signaling or second signaling is received, the protection interval is determined to be the default protection interval, which may be predefined by the standard; In the idle state or initial access situation, if the first signaling is received, the first protection interval indicated by the first signaling is determined as the protection interval; if the first signaling is not received, the protection interval is determined to be the default protection interval. In the connected state, if a second signaling is received, the second protection interval indicated by the second signaling is determined as the protection interval; if no second signaling is received, the protection interval is determined to be the default protection interval.

[0074] In schemes 1-3, the wireless communication node can configure the protection interval through the first signaling and the second signaling. The wireless communication device determines the protection interval based on the first signaling, the second signaling, and / or its own state (idle state, initial access, or connected state). The first signaling can be MIB, PBCH, SIB, or RRC, and the second signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI. The information indicated by the second signaling can be found in the information indicated by the first signaling described above.

[0075] For example, the network side can configure a (maximum) guard interval length G1 (semi-statically) via MIB / PBCH / SIB / RRC. This guard interval length may be greater than the maximum round-trip time (RTD) to ensure that uplink and downlink transmission conflicts are avoided under any circumstances. The network side can also configure a guard interval length G2 (dynamically) via RRC / MAC CE / DCI. This guard interval length may be greater than or less than the maximum RTD, but greater than the current RTD to adapt to the current scenario. When the UE only receives G1 and not G2, the guard interval length G = G1; when the UE only receives G2 and not G1, the guard interval length G = G2; when the UE receives both G1 and G2, the guard interval length G = G2. Alternatively, the network side can configure a guard interval length G1 via MIB / PBCH / SIB / RRC, which may be used in idle mode or during initial access. The UE can determine the initial downlink or uplink resources based on the configuration. The network side can also configure a guard interval length G2 via MIB / PBCH / SIB / RRC / MAC CE / DCI. This guard interval length may be used in connected mode. The UE can determine the downlink or uplink resources in connected mode based on the configuration.

[0076] Scheme 1-4: When the signaling of the wireless communication node includes the first signaling, the second signaling, and the fourth signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no second signaling is received (regardless of whether a fourth signaling is received), or no fourth signaling is received (regardless of whether a second signaling is received), or the fourth signaling indicates that the second signaling is not enabled or not used (regardless of whether a second signaling is received), if the first signaling is received, the first protection interval indicated by the first signaling is determined as the protection interval; if no first signaling is received, the protection interval is determined to be the default protection interval, which may be predefined by the standard. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving a second signaling, or receiving a fourth signaling, or the fourth signaling indicating that the second signaling is enabled or used (regardless of whether the first signaling is received), the second protection interval indicated by the second signaling is determined as the protection interval. In the idle state or initial access situation, if the first signaling is received, the first protection interval indicated by the first signaling is determined as the protection interval; if the first signaling is not received, the protection interval is determined to be the default protection interval. In the connected state, if a second signaling is received, or a fourth signaling is received, or a fourth signaling indicates that the second signaling is enabled or used, then the second protection interval indicated by the second signaling is determined as the protection interval; if no second signaling is received, or no fourth signaling is received, or a fourth signaling indicates that the second signaling is not enabled or not used, then the protection interval is determined as the default protection interval.

[0077] In schemes 1-4, wireless communication nodes can configure the protection interval through the first signaling, the second signaling, and the fourth signaling. The wireless communication device determines the protection interval based on the first signaling, the second signaling, the fourth signaling, and / or its own state (idle state, initial access state, or connected state). Specifically, the first signaling can be MIB, PBCH, SIB, or RRC; the second signaling can be RRC, MAC CE, or DCI; and the fourth signaling can be MIB, PBCH, SIB, or RRC.

[0078] Scheme 1-5: When the signaling of the wireless communication node includes the first signaling and the fifth signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no fifth signaling is received (but the first signaling has been received), the first protection interval indicated by the first signaling is determined as the protection interval; (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving the fifth signaling (after receiving the first signaling), the protection interval is determined according to the first protection interval indicated by the first signaling and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the first protection interval and the first differential protection interval is determined as the protection interval. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no first signaling is received (regardless of whether the fifth signaling is received), the protection interval is determined to be the default protection interval, which may be predefined by the standard. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If the first signaling is not received but the fifth signaling is received, the protection interval is determined according to the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval can be determined as the protection interval. In the idle state or initial access situation, if the first signaling is received, the first protection interval indicated by the first signaling is determined as the protection interval; if the first signaling is received, the protection interval is determined as the default protection interval. In the connected state, if the fifth signaling is received, the protection interval is determined according to the first protection interval indicated by the first signaling and the first differential protection interval indicated by the fifth signaling (the first signaling has been received). For example, the difference or sum of the first protection interval and the first differential protection interval is determined as the protection interval. If the first signaling is received but the fifth signaling is not received, the protection interval is determined as the first protection interval. If the first signaling is not received but the fifth signaling is received, the default protection interval is determined as the protection interval, or the protection interval is determined according to the default protection interval and the first differential protection interval. For example, the difference or sum of the default protection interval and the first differential protection interval is determined as the protection interval. If neither the first nor the fifth signaling is received, the default protection interval is determined as the protection interval.

[0079] In schemes 1-5, wireless communication nodes can configure the protection interval via the first signaling and the fifth signaling. The wireless communication device determines the protection interval based on the first signaling, the fifth signaling, and / or its own state (idle state, initial access, or connected state). The first signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI. The fifth signaling can be RRC, MACCE, or DCI. The information indicated by the fifth signaling can be found in the information indicated by the first signaling described above.

[0080] For example, the network side can configure a (maximum) protection interval length G through MIB / PBCH / SIB / RRC (semi-statically). max The network side can also dynamically configure a differential protection interval length ΔG via RRC / MAC CE / DCI. The protection interval length G = G max -ΔG, where ΔG = 0 if ΔG is not configured by the network.

[0081] Scheme 1-6: When the signaling of the wireless communication node includes the first signaling, the fifth signaling, and the sixth signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in idle state, initial access state, or connected state) If no fifth signaling is received, or no sixth signaling is received, or the sixth signaling indicates that the fifth signaling is not enabled or not used (if the first signaling has been received), the first protection interval indicated by the first signaling is determined as the protection interval. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving the fifth signaling, or receiving the sixth signaling, or the sixth signaling indicating that the fifth signaling is enabled or used (after receiving the first signaling and the fifth signaling), the protection interval is determined according to the first protection interval indicated by the first signaling and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the first protection interval and the first differential protection interval is determined as the protection interval. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no first signaling is received (regardless of whether the fifth and sixth signaling are received), the protection interval is determined to be the default protection interval, which can be predefined by the standard. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no first signaling is received, but a fifth signaling is received, or a sixth signaling is received, or the sixth signaling indicates that the fifth signaling is enabled or used, the protection interval is determined according to the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval is determined as the protection interval. In the idle state or initial access situation, if the first signaling is received, the first protection interval indicated by the first signaling is determined as the protection interval; if the first signaling is not received, the protection interval is determined to be the default protection interval. In the connected state, if a fifth signaling signal is received, or a sixth signaling signal is received, or the sixth signaling signal indicates that the fifth signaling signal is enabled or used, then the protection interval is determined according to the first protection interval indicated by the first signaling signal and the first differential protection interval indicated by the fifth signaling signal. For example, the difference or sum of the first protection interval and the first differential protection interval is determined as the protection interval. If the first signaling signal is received, but the fifth signaling signal is not received, or the sixth signaling signal is not received, or the sixth signaling signal indicates that the fifth signaling signal is not enabled or used, then the protection interval is determined as the first protection interval. If the first signaling signal is not received, but the fifth signaling signal is received, or the sixth signaling signal is received, or the sixth signaling signal indicates that the fifth signaling signal is enabled or used, then the default protection interval is confirmed as the protection interval, or the protection interval is determined according to the default protection interval and the first differential protection interval. For example, the difference or sum of the default protection interval and the first differential protection interval is determined as the protection interval. If neither the first nor the fifth signaling signal is received, then the default protection interval is confirmed as the protection interval.

[0082] In schemes 1-6, wireless communication nodes can configure the protection interval through the first signaling, the fifth signaling, and the sixth signaling. The wireless communication device determines the protection interval based on the first signaling, the fifth signaling, the sixth signaling, and / or its own state (idle state, initial access, or connected state). The first signaling can be MIB, PBCH, SIB, or RRC. The fifth signaling can be RRC, MAC CE, or DCI. The sixth signaling can be MIB, PBCH, SIB, or RRC.

[0083] Scheme 1-7: When the signaling of the wireless communication node includes the fifth signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) In the absence of receiving the fifth signaling, the wireless communication device can determine the guard interval as the default guard interval, which may be predefined by the standard; (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving the fifth signaling, the protection interval is determined based on the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval is determined as the protection interval. In the idle state or during initial access, the wireless communication device can determine the guard interval as the default guard interval, which may be predefined by the standard; In the connected state, the protection interval is determined based on the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval is used to determine the protection interval.

[0084] In schemes 1-7, wireless communication nodes can configure the protection interval via the fifth signaling. The wireless communication device determines the protection interval based on the fifth signaling and / or its own state (idle state, initial access, or connected state). The fifth signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI. The information indicated by the fifth signaling can be found in the information indicated by the first signaling described above.

[0085] For example, a standard can predefine a protection interval length G. default On the network side, a differential protection interval length ΔG can be configured via MIB / PBCH / SIB / RRC / MAC CE / DCI. The protection interval length G = G0 defaul -ΔG or G=G defaul +ΔG. Or, in the idle state or upon initial access, G=G. defaul In the connected state or upon receiving the fifth signaling, G=G defaul-ΔG or G=G defaul +ΔG. Where ΔG is not configured by the network, then ΔG=0.

[0086] Scheme 1-8: When the signaling of the wireless communication node includes the fifth and sixth signaling, the protection interval is determined based on the status of the wireless communication device and / or the signaling of the wireless communication node, including at least one of the following: (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) If no fifth signaling is received, or no sixth signaling is received, or the sixth signaling indicates that the fifth signaling is not enabled or not used, the default protection interval will be determined as the protection interval. The default protection interval may be predefined by the standard. (Regardless of whether the wireless communication device is in an idle state, an initial access state, or a connected state) Upon receiving the fifth signaling, or receiving the sixth signaling, or the sixth signaling indicating that the fifth signaling is enabled or used, the protection interval is determined according to the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval is determined as the protection interval. In the idle state or during initial access, the wireless communication device can determine the guard interval as the default guard interval, which may be predefined by the standard; In the connected state, if no fifth signaling is received, or no sixth signaling is received, or the sixth signaling indicates that the fifth signaling is not enabled or not used, the default protection interval will be determined as the protection interval. The default protection interval may be predefined by the standard. If the fifth signaling is received, or the sixth signaling is received, or the sixth signaling indicates that the fifth signaling is enabled or used, the protection interval will be determined according to the default protection interval and the first differential protection interval indicated by the fifth signaling. For example, the difference or sum of the default protection interval and the first differential protection interval will be determined as the protection interval.

[0087] In schemes 1-8, wireless communication nodes can configure the protection interval via the fifth and sixth signaling. The wireless communication device determines the protection interval based on the fifth and sixth signaling and / or its own state (idle state, initial access, or connected state). The fifth signaling can be MIB, PBCH, SIB, RRC, MAC CE, or DCI. The sixth signaling can be MIB, PBCH, SIB, or RRC. The information indicated by the fifth signaling can be found in the information indicated by the first signaling described above.

[0088] The unit of the length or offset of the protection interval configured by the signaling may be at least one of the following: superframe, frame, subframe, time slot, symbol, millisecond, or a unit at the millisecond level (such as 10ms).

[0089] The aforementioned start time (also known as the initial time) or end time (also known as the termination time) may be at least one of the following: superframe number, frame number, subframe number, time slot number, symbol number, or absolute time such as year, month, day, hour, minute, second, millisecond, microsecond, etc.

[0090] The above protection interval configuration may include configuring multiple protection intervals. For example, the network side can configure the following two protection intervals: The protection interval or offset between the downlink time and the start time of the cycle mode, such as the protection interval or offset between the start time of the downlink time and the start time of the cycle mode. The protection interval or offset between downlink and uplink times, such as the protection interval or offset between downlink and uplink times in the same cycle pattern.

[0091] The configuration of multiple protection intervals may be achieved through the same signaling or through multiple signaling (each corresponding to a different protection interval). When multiple signaling is used to configure protection intervals (e.g., the first and second signaling in schemes 1-2 and 1-3), some information may be configured through a unified signaling, while other information may be configured through multiple signaling (each corresponding to a different protection interval). For example, two protection intervals may have their maximum length configured through two IEs in the same SIB, and then their differential length configured through two different MAC CEs. Alternatively, two protection intervals may have their maximum length configured through two IEs in the same SIB, and then their differential length configured through different bit fields of the same MAC CE. Examples of multiple protection interval configuration methods will not be provided here.

[0092] Wireless communication devices can determine the downlink time based on a periodic pattern and a guard interval. For example, the device can determine the start time of the periodic pattern based on NPSS or NSSS detection or network-side configuration. The network side configures the guard interval as described above, such as the interval or offset between the start time of the downlink time and the start time of the periodic pattern. The device can then determine the downlink time or the start time of the downlink time based on the periodic pattern and the guard interval. For example, the start time T of the downlink time... DL,start = T pattern,start +G pattern-DL T pattern,start G is the start time of the periodic pattern. pattern-DL The downlink time is the interval or offset between the start time of the downlink and the start time of the periodic pattern. Alternatively, a standard predefined default / fixed downlink time. The network side configures additional offsets or additional intervals according to the above method. The UE determines the downlink time based on the default / fixed downlink time and the additional offsets or additional intervals configured by the network side. For example, the default / fixed downlink time is determined according to at least one of the following methods: The standard predefines the length of the downlink time. For example, the standard may predefine the downlink time length as N subframes.

[0093] The standard predefines the interval or offset between the start time of downlink time and the start time of periodic mode. For example, the standard may predefine the interval or offset between the start time of downlink time and the start time of periodic mode as N subframes.

[0094] The standard predefines the interval or offset between the start time of the downlink time and the start time of the time unit (e.g., time slot / subframe / frame / superframe) in which the downlink time begins. For example, the standard may predefine the interval or offset between the start time of the downlink time and the start time of the time slot / subframe / frame / superframe in which the downlink time begins as N subframes. Alternatively, the standard may predefine the start time of the downlink time as subframe N.

[0095] The standard predefines downlink timing patterns, such as the time slot / subframe / frame / superframe in which the downlink timing occurs (e.g., the time slot / subframe / frame / superframe sequence number within one or N time units). More specifically, the standard may predefine subframes {X,X+1,…,M,0,1,…,Y} in which the downlink timing occurs within two consecutive frames. Here, X~M are the subframes in the first frame in which the downlink timing occurs, and 0~Y are the subframes in the second frame in which the downlink timing occurs. For example... Figure 4 As shown.

[0096] The network side configures the additional offset or additional interval according to the above method, possibly through schemes 1-1 to 1-8, changing the configuration or determination of the protection interval to the configuration or determination of the additional offset or additional interval. The additional offset or additional interval may refer to the offset or interval between the start time of the downlink time (e.g., the target downlink time or the configured downlink time) and the start time of the default / fixed downlink time, or it may refer to the additional interval between the start time of the downlink time (e.g., the target downlink time or the configured downlink time) and the start time of the periodic mode (compared to the interval between the start time of the default / fixed downlink time and the start time of the periodic mode). For example... Figure 4 As shown.

[0097] Furthermore, wireless communication devices can determine the uplink time based on the downlink time and guard interval. For example, the wireless communication device can determine the downlink time based on NPSS or NSSS detection or network-side configuration. The network side configures the guard interval in the manner described above, such as the offset between the start time of the downlink time and the start time of the uplink time, or the interval between the end time of the downlink time and the start time of the uplink time. The wireless communication device can determine the uplink time or the start time of the uplink time based on the downlink time and the guard interval. For example, the start time T of the uplink time... UL,start =T DL,start +GDL-UL T DL,start G is the start time of the downlink time. DL-UL This is the offset between the start time of the downlink time and the start time of the uplink time. Alternatively, it's the start time T of the uplink time. UL,start =T DL,end + G DL-UL T DL,end G is the end time of the downlink time. DL-UL This is the interval between the end time of the downlink time and the start time of the uplink time. Alternatively, it's the start time T of the uplink time. UL,start = T pattern,start +G pattern-DL +G DL-UL T pattern,start G is the start time of the periodic pattern. pattern-DL G is the interval between the start time of the downlink time and the start time of the periodic pattern. DL-UL This is the offset between the start time of the downlink time and the start time of the uplink time. Alternatively, it's the start time T of the uplink time. UL,start = T pattern,start +G pattern-DL +D DL +G DL-UL T pattern,start G is the start time of the periodic pattern. pattern-DL D represents the interval between the start time of the downlink time and the start time of the periodic pattern. DL G represents the duration of the downlink time. DL-UL This is the interval between the end time of the downlink time and the start time of the uplink time.

[0098] It is worth noting that in some implementations, the length of the periodic pattern may not be divisible by the length of the superframe H-SFN. For example, the length of the periodic pattern may be 90ms (or 9 system frames, or 90 subframes), while the length of a superframe (i.e., the system frame wrap-around period, SFN wrap-around periodicity) is 10240ms (or 1024 system frames, or 10240 subframes) in a conventional system. Thus, if the first periodic pattern begins in the first system frame within the first superframe, after applying the periodic pattern consecutively, there will be 7 system frames remaining, insufficient time to apply a 9-frame periodic pattern. Figure 5 As shown. In this case, if the periodic mode continues to be applied, it will occupy the first 20ms of the next superframe, causing the resource mapping of the periodic mode in the next superframe to be different from that in the first superframe. For this situation, embodiments of this application provide corresponding processing solutions, which may include at least one of the following solutions 1-9 and 1-10: Schemes 1-9: The resource mapping is the same for different intra-frame periodic modes.

[0099] Scheme 1-10: The resource mapping is different for different intra-frame periodic modes. The resource mapping for each intra-frame periodic mode is determined by the system frame in which the detection channel is located.

[0100] Schemes 1-9 ensure that the periodic pattern mapping remains consistent within each superframe. This allows wireless communication devices and nodes to quickly determine the resources available for downlink and / or uplink transmission within each superframe, facilitating implementation and scheduling. Schemes 1-10 apply the periodic pattern continuously, allowing for different resource mappings for the periodic pattern in different superframes. Wireless communication devices can determine the system frame containing the detected channel through channel detection, and then determine the resource mapping for the periodic pattern based on that system frame (through calculation). The detected channel may include, but is not limited to, PSS, SSS, PBCH, etc.

[0101] For schemes 1-9, in order to determine that the resource mappings of different intra-frame periodic modes are the same, at least one of the following schemes 1-9-1 and 1-9-2 can be used, that is, the resource mappings of different intra-frame periodic modes are the same, which can include at least one of the following schemes 1-9-1 and 1-9-2: Scheme 1-9-1: Within each superframe, the start time of the first periodic pattern is the first system frame, and the frame number of the first system frame is equal to the remainder of the number of system frames within the superframe and the length of the periodic pattern.

[0102] For example, within each superframe, the start time of the first periodic pattern is the start time of system frame X, where X = mod(M, N), M is the number of system frames in a superframe, and N is the length of the periodic pattern (in system frames). Then, within each superframe, periodic patterns are applied consecutively, and the end time of the last periodic pattern can be aligned with the last system frame in the superframe. Scheme 1-9-2: Within each superframe, the start time of the first cycle pattern is the same, and the last cycle pattern is a truncated cycle pattern.

[0103] For example, at the start of each superframe, the periodic pattern mapping is reset. Specifically, the start time of the first periodic pattern within each superframe remains consistent. Then, within each superframe, the periodic pattern is applied continuously, and at the end of the superframe, if the periodic pattern has not ended, it is truncated, as shown in Figure 6(a). Alternatively, the application of periodic patterns or resource mapping within a superframe may not continue into the next superframe.

[0104] Scheme 1-9-3: Within each superframe, the start time of the first cycle pattern is the same, and the end time of the last cycle pattern is before the end time of the superframe.

[0105] For example, at the start of each superframe, the mapping of periodic patterns is reset. Specifically, the start time of the first periodic pattern within each superframe remains consistent. Then, within each superframe, periodic patterns are applied continuously. After a periodic pattern ends, if the remaining time in the current superframe or the remaining time before the SFN wrap around is insufficient to apply / accommodate / complete a periodic pattern, then a (new) periodic pattern will not be applied / started, or the application of the periodic pattern will be stopped, or the remaining time will be skipped, as shown in Figure 6(b).

[0106] The configuration interval or offset described in this application may be implemented in at least one of the following ways: The network side can directly configure the interval or offset length. For example, a bit field can be defined, and each state or value of the bit field corresponds to an interval or offset.

[0107] The standard predefines multiple alternative values. The network side configures one or more values ​​from these. For example, an RRC signaling can be defined, which can indicate an enumeration of multiple alternative values.

[0108] The standard predefines multiple alternative values, or the network side configures multiple alternative values. The network side indicates the index of the alternative value. For example, the standard predefines or the network side configures alternative values ​​{X1, X2, ..., X...} N The network side may indicate index M to indicate a value of X. M .

[0109] Example 2: How a wireless communication device determines the time-domain resources of a first transmission when the transmission resources include the time-domain resources of the first transmission.

[0110] In some implementations, the wireless communication device determines the time-domain resources for the first transmission, which may include at least one of the following first, second, third, and fourth methods: Method 1: Delay the first transmission.

[0111] In cases where the first transmission is delayed, some implementations may include at least one of the following: Delay the first transmission to the next transmission time segment or the next transmission time unit; The portion of the first transmission that overlaps with non-transmission time is delayed to the next transmission time segment or the next transmission time unit. The transmission time unit may include at least one of superframe, frame, subframe, time slot, resource unit, transport block, repeated transmission, symbol, and millisecond. The next transmission time unit may include the next available or valid transmission time unit, or the next transmission time unit that does not overlap with other transmissions, or the next non-reserved transmission time unit, or the next first transmission time unit, which spans multiple transmission time units.

[0112] Taking a downlink transmission that does not overlap with a non-downlink time unit as an example, when delaying a downlink transmission that does not overlap with a non-downlink time unit, the delay can be to the next downlink time segment or the next downlink time unit, etc. The delay may only delay the transmission of the overlapping portion (as shown in Figure 7), or it may delay the transmission over the entire overlapping time unit (as shown in Figure 8). The downlink time unit, as mentioned above, may refer to a downlink frame, subframe, symbol, etc. The delay may be to the next most recently available / valid time unit, or to the next time unit that does not overlap with other channels / signals, or to the next non-reserved time unit, or to the next first time unit (a first time unit can span two or more consecutive second time units; for example, a time slot can span two subframes, where any second time unit does not overlap with other channels / signals, is available, valid, or non-reserved). The delay to the next time unit may refer to the delay to the next complete time unit. When multiple downlink transmissions are delayed, the delays are performed sequentially. For example, after the first downlink transmission is delayed, the time unit to which the second downlink transmission can be delayed is determined (e.g., delayed to the next downlink time unit after the time unit used by the first downlink transmission's delayed transmission).

[0113] Second method: Discard the first transmission.

[0114] In cases where the first transmission is discarded, some implementations may include at least one of the following: Discard or not transmit the first transmission; Discard or not transmit the portion of the first transmission that overlaps with non-transmission time; Discard or not transmit the entire transmission time unit in the first transmission that overlaps with the non-transmission time.

[0115] Taking a downlink transmission that overlaps with a non-downlink time as an example, when discarding a downlink transmission that overlaps with a non-downlink time, it might mean canceling the downlink transmission altogether. For example, the network side might not send the overlapping portion of the downlink transmission. Alternatively, the network side might send the overlapping portion of the downlink transmission, but the UE doesn't receive it. The discarding might involve discarding the overlapping portion of the downlink transmission (e.g., ...). Figure 9As shown in Figure 10, the transmissions may be discarded, or the entire downlink transmission may be discarded. The downlink time unit, as previously described, may refer to a downlink frame, subframe, symbol, etc. More specifically, for example, the first transmission is repeated N times, each repetition occupying M downlink subframes, where the Y-th downlink subframe of the X-th repetition begins to overlap with non-downlink time. Discarding could mean discarding all N repetitions, or discarding the Xth to Nth repetitions, or discarding the Y-th to M-th downlink subframes and the (X+1)th to Nth repetitions of the X-th repetition, etc.

[0116] The third approach is to either not use the time-domain resources of the first transmission in the transmission resource mapping, or to use only the time-domain resources of the transmission time in the transmission resource mapping.

[0117] For example, PDSCH can be mapped onto downlink subframes 1 to N, which may be distributed across discontinuous downlink times.

[0118] Fourth method: Based on the transmission information of the first transmission, at least two of the first, second and third methods mentioned above are selected to determine the time domain resources of the first transmission. Different transmission information corresponds to different methods.

[0119] The fourth approach is a combination of at least two of the first, second, and third approaches mentioned above. In specific implementations, the standard or network may support multiple approaches (at least two of the first, second, and third approaches mentioned above). The wireless communication device can select one of these multiple approaches to determine the transmission resources for the first transmission based on the transmission information of the first transmission. For example, the standard may define or the network may configure multiple scenarios, using different approaches for different scenarios; or, different approaches may be used for different first transmissions with different transmission information (such as different downlink channels or reference signals).

[0120] In some implementations, the transmission information of the first transmission may include at least one of the following (1) to (13): (1) The overlap duration of the first transmission and non-transmission time.

[0121] Different overlap durations can be handled using different methods. In specific implementations, the network side can indicate a threshold or a threshold predefined by the standard, and the UE can choose different methods based on the relationship between the overlap duration and the threshold. Taking downlink transmission as an example, when the overlap length between a downlink transmission and a non-downlink time is greater than or equal to the threshold, the downlink transmission is discarded; otherwise, the downlink transmission is delayed (as shown in Figure 11). Alternatively, when the overlap length between a downlink transmission and a non-downlink time is greater than or equal to the threshold, the first T portion of the overlap between the downlink transmission and the non-downlink time is delayed, and the remaining portion is discarded. This can alleviate congestion caused by excessive delays.

[0122] (2) The ratio of the overlap between the first transmission and non-transmission time to the total transmission time.

[0123] Different proportions can be handled in different ways. In specific implementations, the network side can indicate a threshold or a threshold can be predefined by the standard. The UE can choose different methods based on the relationship between the proportion and the threshold. Taking downlink transmission as an example, when the proportion of the time length of the overlap between (a) downlink transmission and non-downlink time is greater than (or equal to) the threshold of the total downlink transmission time, the downlink transmission is discarded; otherwise, the downlink transmission is delayed. Alternatively, when the proportion of the time length of the overlap between (a) downlink transmission and non-downlink time is greater than (or equal to) the threshold of the total downlink transmission time, the first T part of the overlap between the downlink transmission and non-downlink time is delayed, so that the proportion of the discarded time length to the total time length is less than (or equal to) R, and the remaining part is discarded.

[0124] (3) The length of time during which the (cumulative) first transmission and non-transmission times overlap until the start of the next transmission time.

[0125] Different time lengths can be handled using different methods. In specific implementations, the network side can indicate a threshold or a threshold predefined by the standard, and the UE can choose different methods based on the relationship between the time length and the threshold. Taking downlink transmission as an example, when the time length is greater than (or equal to) the threshold, the downlink transmission is discarded; otherwise, the downlink transmission is delayed. Alternatively, the first T portion of the downlink transmission overlapping with the non-downlink time is delayed, and the remaining portion is discarded. This can alleviate congestion caused by excessive delay.

[0126] (4) Signal strength of the first transmission.

[0127] Signal strength includes, but is not limited to, at least one of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), and Signal to Interference plus Noise Ratio (SINR). Different signal strengths can be handled using different methods. In specific implementations, the network side can indicate a threshold or a threshold predefined by the standard, and the UE can choose different methods based on the relationship between the signal strength and the threshold. Taking downlink transmission as an example, when the signal strength is greater than (or equal to) the threshold, downlink transmission is dropped; otherwise, downlink transmission is delayed. Alternatively, when the signal strength is greater than (or equal to) the threshold, downlink transmission is delayed; otherwise, downlink transmission is dropped. At low SINR, a large number of repeated transmissions may be required to increase downlink transmission and non-transmission time; in this case, dropping transmissions may be necessary to alleviate congestion.

[0128] (5) The modulation order or code rate of the first transmission.

[0129] The modulation order or code rate can be, for example, a modulation and coding scheme (MCS). Different modulation orders or code rates can use different methods. In specific implementations, the network side can indicate a threshold or a threshold predefined by the standard, and the UE can choose different methods based on the relationship between the modulation order or code rate and the threshold. Taking downlink transmission as an example, when the modulation order or code rate is greater than (or equal to) the threshold, the downlink transmission is discarded; otherwise, the downlink transmission is delayed. Alternatively, when it is greater than (or equal to) the threshold, the downlink transmission is delayed; otherwise, the downlink transmission is discarded.

[0130] (6) Coverage level of the first transmission.

[0131] Coverage levels can be, for example, CElevel in NB-IoT systems or CEmode in eMTC systems. In specific implementations, the network side can indicate a threshold or a threshold predefined by the standard, and the UE can choose different methods based on the relationship between the modulation order or code rate and the threshold.

[0132] It should be noted that in (1) to (6) above, if the network side does not configure the threshold or the standard does not predefine the threshold, the above threshold may have a default value, such as 0, infinity, an uplink / downlink transmission time length, or a defined value.

[0133] (7) The overlap of the first transmission and non-transmission time.

[0134] Different overlap patterns can use different schemes. Taking downlink transmission as an example, for downlink transmissions that completely overlap with non-downlink times, the downlink transmission is discarded. For downlink transmissions that partially overlap with non-downlink times, the downlink transmission is delayed.

[0135] (8) The scheduling or configuration method of the first transmission.

[0136] Different scheduling or configuration methods can use different schemes. Taking downlink transmission as an example, for semi-static downlink configuration, downlink transmission is discarded. For dynamically scheduled downlink transmission, downlink transmission is delayed. Dynamic scheduling refers to the network sending DCI to schedule or instruct the UE to receive DL signals or send UL signals. Semi-static configuration refers to the network configuring the UE to receive DL signals or send UL signals through higher-layer parameters, such as SPS.

[0137] (9) The signal or channel corresponding to the first transmission.

[0138] Different channels or signals can use different schemes. Taking downlink transmission as an example, for the first downlink transmission, the downlink transmission is discarded. For the second downlink transmission, the downlink transmission is delayed. For example, the first downlink transmission may refer to CSI-RS, PDCCH, common PDCCH (e.g., PDCCH configured with a common search space set, such as Type-0 / 0A / 1 / 2 / 3), or downlink transmission scheduled by common PDCCH. The second downlink transmission may refer to UE-specific PDCCH, PDSCH, or PDSCH scheduled by UE-specific PDCCH. In addition, different channels here may contain different types of the same channel, such as different types of PDCCH. For example, the first downlink transmission may refer to the PDCCH corresponding to SI-RNTI. The second downlink transmission may refer to the PDCCH corresponding to P-RNTI.

[0139] (10) In the case of a delayed first transmission, whether the delayed first transmission can be completed in the next transmission time or still overlaps with the non-transmission time.

[0140] Taking downlink transmission as an example, when downlink transmission is delayed, if the delayed downlink transmission cannot be completed within the next downlink time period, or if the delayed downlink transmission still overlaps with a non-downlink time period, then the downlink transmission is discarded. The discarded downlink transmission may be a downlink transmission that still overlaps with a non-downlink time period after the delay, or it may include all delayed downlink transmissions from that current downlink transmission until the next downlink time period.

[0141] (11) In the case of a delayed first transmission, whether the delayed first transmission occurs after the start time of the next or another downlink transmission.

[0142] Taking downlink transmission as an example, when downlink transmission is delayed, if the delayed downlink transmission is not completed by the start of the next / another downlink transmission (e.g., a newly scheduled downlink transmission), the downlink transmission is discarded. The discarded downlink transmission may be a downlink transmission that has not been completed after the start of the next / another downlink transmission, or a downlink transmission whose delayed time resource is after the start time of the next / another downlink transmission.

[0143] (12) In the case of a delayed first transmission, is the delayed first transmission after the end time of the time window?

[0144] Taking downlink transmission as an example, when downlink transmission is delayed, if the delayed downlink transmission is not completed by the end of the downlink time window (e.g., the System Message Time Window (SI window), Random Access Response Time Window (RAR window), etc.), the downlink transmission will be discarded or truncated. The discarded downlink transmission may be a downlink transmission that was not completed by the end of the time window, or a downlink transmission whose time resources are delayed and occur after the end of the time window.

[0145] (13) In the case of a delayed first transmission, does the delayed first transmission overlap with a normal or non-delayed transmission during the transmission time?

[0146] Taking downlink transmission as an example, when downlink transmission is delayed, if the delayed downlink transmission overlaps with normal / non-delayed downlink transmissions within the downlink time period, the downlink transmission is discarded. The discarded downlink transmission may be the downlink transmission that overlaps with normal / non-delayed downlink transmissions within the downlink time period after the delay, or it may include all delayed downlink transmissions after the delayed downlink transmission and before the normal / non-delayed downlink transmissions.

[0147] It should be noted that the above schemes (1) to (13) can be used in combination. For example, taking downlink transmission as an example, schemes (1) to (6) and scheme (9) can be combined. For the first downlink transmission, the downlink transmission is discarded. For the second downlink transmission, a threshold is introduced (e.g., the length of time that the downlink transmission overlaps with the non-downlink time). If the threshold is greater than or equal to the threshold, the downlink transmission is discarded; otherwise, the downlink transmission is delayed.

[0148] The fifth method involves determining the time-domain resources of the first transmission based on the indication information of the wireless communication node, wherein the indication information is used to indicate one of the first, second, third, and fourth methods described above.

[0149] Specifically, the standard or network may support multiple methods (at least two of the first, second, third, and fourth methods mentioned above), and the network side may use signaling to indicate which method to apply. Optionally, if the network side does not provide signaling, one of the methods may be used by default.

[0150] For example, the network side supports two processing schemes: delay and drop. The network side indicates the specific scheme to be used through signaling. If the network side indicates support for / application of the delay scheme, then downlink transmissions are delayed when they overlap with non-downlink times. If the network side indicates support for / application of the drop scheme, then downlink transmissions are dropped when they overlap with non-downlink times. If the network side does not indicate support, downlink transmissions are either dropped or delayed by default.

[0151] For example, if there is no indication signaling on the network side, downlink transmissions are dropped by default; if there is indication signaling on the network side, downlink transmissions are delayed. Alternatively, if there is no indication signaling on the network side, downlink transmissions are delayed by default; if there is indication signaling on the network side, downlink transmissions are dropped.

[0152] It is worth noting that, when the first transmission is an uplink transmission, to improve the system capacity in NTN, code division multiplexing, such as orthogonal covering code (OCC), can be considered for different users. To better understand the principle of OCC, let's take the sequence [+1 +1; +1 -1] as an example. UE1 selects the sequence [+1 +1], and UE2 selects the sequence [+1 -1]. Each UE repeats this sequence twice, with the same content. UE1 and UE2 transmit X1 and X2 respectively on the same time and frequency domain resources. Therefore, the signals superimposed at the positions of the first and second repetitions can be represented as Y1 and Y2. Figure 12 As shown, X1 and X2 can be calculated as functions of Y1 and Y2 and their corresponding channel state information.

[0153] from Figure 12 As can be seen, when using OCC codes, it is necessary to ensure that the channel state remains consistent during repeated transmissions; otherwise, interference may occur. Therefore, within an OCC group (i.e., multiple repeated transmissions using the same OCC), it is necessary to ensure the consistency or continuity of the uplink transmission phase or power as much as possible. However, when using TDD mode, due to the existence of downlink transmission and guard intervals, it is difficult to guarantee the consistency of phase or power in an uplink transmission spanning multiple cycle modes. Taking a 2-length OCC code [w1, w2] as an example, each element within the OCC code is applied to a transmission corresponding to a certain granularity (e.g., symbol, time slot, time slot group, repetition, etc.). Figure 13 This is an example of an OCC code application that spans multiple intervals. Figure 13 The "previous transmission" in the interval refers to a data transmission cycle before the current interval, and the "next transmission" refers to a data transmission cycle after the current interval. A transmission cycle contains at least one symbol, time slot, or repeated transmission at the repeated transmission level. The interval may include a guard interval, downlink transmission time, or invalid time units (e.g., invalid subframes). To avoid or mitigate interference caused by phase or power discontinuities, enhancement schemes may be considered for uplink transmission. Specifically, these may include at least one of the following schemes 2-1 to 2-3: Option 2-1: Apply orthogonal overlay code (OCC) in non-cycle-crossing mode, or apply OCC not in non-uplink time, or apply OCC to repeated transmissions in continuous uplink time.

[0154] In practical implementation, the network side ensures during configuration that OCC application does not span cycle modes, or that OCC application can only be performed within the same uplink time segment. UEs do not expect OCC to be applied across cycle modes, or do not expect elements applying OCC to overlap with non-uplink times, or only apply OCC to repeated transmissions within consecutive uplink times.

[0155] Scheme 2-2: When applying OCC, if elements belonging to the same OCC code are separated by intervals or belong to different periodic patterns, the transmissions of elements belonging to the same OCC code on both sides of the interval or in different periodic patterns will be discarded.

[0156] That is, when elements belonging to the same OCC code are spaced apart or belong to different periodic patterns during application, the transmissions of elements belonging to the same OCC code on either side of the space or in different periodic patterns are discarded. For example, this method can be considered if uplink transmission is delayed due to overlap with non-uplink times. For instance, in... Figure 13 In the example shown, the transmission corresponding to the application unit [w1, w2] is discarded.

[0157] Scheme 2-3: When applying OCC, if elements belonging to the same OCC code are separated by intervals or belong to different periodic patterns, the transmission of elements belonging to the same OCC code on both sides of the interval or in different periodic patterns will be delayed to the next uplink time.

[0158] In other words, when elements belonging to the same OCC code are separated by intervals or belong to different periodic patterns during application, the transmission of elements belonging to the same OCC code on either side of the interval or in different periodic patterns is postponed to the next uplink time. For example, the transmission of elements corresponding to each OCC code can be postponed to after the interval, or postponed to the uplink time of the next periodic pattern. This method can be considered if uplink transmission is delayed when it overlaps with non-uplink time. For example, in... Figure 13 In the example shown, the transmissions corresponding to the application units [w1, w2] are postponed to the next transmission cycle, as shown in Figure 14.

[0159] Scheme 2-4: When applying OCC, if at least one application unit among the elements belonging to the same OCC code is discarded, then the transmissions corresponding to the elements belonging to the same OCC code will be discarded.

[0160] That is, when elements belonging to the same OCC code are used, if at least one application unit is discarded, the transmissions corresponding to all elements belonging to the same OCC code are also discarded. For example, this method can be considered if uplink transmissions are discarded when they overlap with non-uplink times.

[0161] It is worth noting that the enhancements related to orthogonal covering codes (OCC) described in the embodiments of this application can be applied to any code or covering code, including orthogonal and non-orthogonal codes. For example, codes composed of any orthogonal code sequences include, but are not limited to, Walsh codes, Discrete Fourier Transform (DFT) codes, etc. For example, codes composed of non-orthogonal code sequences include, but are not limited to, codes or access codes for Non-Orthogonal Multiple Access (NOMA).

[0162] Example 3: How a wireless communication device determines the time-domain resources of a second transmission when the transmission resources include the time-domain resources of the second transmission.

[0163] In some implementations, the wireless communication device determines the time-domain resources for the second transmission, including: The time domain resources for the second transmission are determined based on the reception time of the first downlink transmission.

[0164] The second transmission can be either an uplink or downlink transmission, and the timing of sending or receiving the second transmission can be determined based on the reception time of the first downlink transmission. When determining the time-domain resources for the second transmission based on the reception time of the first downlink transmission, some implementations may include at least one of the following schemes 3-1 and 3-3: Scheme 3-1: When the first downlink transmission is received at the first downlink time and the second transmission is a downlink transmission, the first downlink time is determined as the time domain resource of the second transmission.

[0165] That is, if the first downlink transmission is received at the first downlink time and the second transmission is also a downlink transmission, the second transmission can be received or transmitted at the first downlink time. In this case, the scheduling delay between the second and first transmissions is the same as in conventional / FDD / terrestrial networks.

[0166] Scheme 3-2: When the first downlink transmission is received at the first downlink time and the second transmission is a downlink transmission, the second downlink time after the first downlink time is determined as the time domain resource of the second transmission.

[0167] That is, if the first downlink transmission is received at the first downlink time and the second transmission is also a downlink transmission, the second transmission can be received or transmitted at the second downlink time after the first downlink time. The second downlink time can be, for example, the next downlink time after the first downlink time.

[0168] Specifically, if the first downlink transmission ends in subframe / timeslot n, then the second transmission begins in subframe / timeslot n+k+deltak. Here, n+k is the reference subframe / timeslot / time, or the subframe / timeslot at which the second transmission begins in a traditional / FDD / terrestrial network. deltak is the offset / interval / delay between the second transmission starting subframe / timeslot and the reference subframe / timeslot / time, or the additional delay in an NTN / TDD network.

[0169] The value of deltak can be: zero, the period / length of the periodic mode, the period of the downlink time, the interval of the downlink time (the interval between the end time of the previous downlink time and the start time of the next downlink time), the interval of the downlink time plus the offset X, or a network-side configuration. X can be positive, negative, or zero. X may be the offset / interval between the reference subframe / slot / time and the end time of the first downlink time.

[0170] Schemes 3-1 and 3-2 can be combined. For example, if the second transmission can be completed according to Scheme 3-1 (i.e., the second transmission does not overlap with non-downlink time according to the scheduling delay of traditional / FDD / terrestrial networks), then the second transmission is received according to Scheme 3-1. If the second transmission overlaps with non-downlink time according to Scheme 3-1, then the second transmission is received according to Scheme 3-2.

[0171] As another implementation, it can be considered a combination of schemes 3-1 and 3-2, where deltak takes different values ​​under different conditions. For example, when deltak=0, the second transmission does not overlap with non-downlink time, so deltak=0. If deltak=0, the second transmission overlaps with non-downlink time, then deltak is the downlink time interval plus the offset X.

[0172] Scheme 3-3: When the first downlink transmission is received at the first downlink time and the second transmission is an uplink transmission, the first uplink time after the first downlink time is determined as the time domain resource of the second transmission.

[0173] That is, if the first downlink transmission is received at the first downlink time and the second transmission is an uplink transmission, the second transmission can be sent at the first uplink time. The first uplink time can be, for example, the first uplink time after the first downlink time, or the first uplink time after a reference subframe / slot / time.

[0174] Specifically, if the first transmission ends in subframe / time slot n, then the second transmission begins in subframe / time slot n+k+deltak. Here, n+k is the reference subframe / time slot / time, or the subframe / time slot at which the second transmission begins in a traditional / FDD / terrestrial network. deltak is the offset / interval / delay between the second transmission's starting subframe / time slot and the reference subframe / time slot / time, or the additional delay in an NTNTDD network.

[0175] The value of deltak can be: zero, the offset between uplink and downlink times (e.g., the interval between the start time of downlink time and the start time of uplink time), the interval between uplink and downlink times (e.g., the interval between the end time of downlink time and the start time of uplink time), the interval between uplink and downlink times plus offset X, or a network-side configuration. X can be positive, negative, or zero. X may be the offset / interval between the reference subframe / slot / time and the end time of the first downlink time.

[0176] deltak may take different values ​​depending on the situation. For example, when deltak=0, the second transmission does not overlap with a non-uplink time, so deltak=0. If deltak=0, the second transmission overlaps with a non-uplink time, then deltak is the interval between the uplink and downlink times plus an offset X.

[0177] Example 4: How a wireless communication device determines a time window when transmission resources include a time window.

[0178] In some implementations, the wireless communication device determines the time window, which may include at least one of the following schemes 4-1 to 4-7: Option 4-1: Do not modify the definition or parameters of the time window.

[0179] For example, when a downlink transmission overlaps with a non-downlink transmission time and a scheme to discard downlink transmission is used (i.e., the second method in the above embodiment 2), the downlink transmission can be completed within the original time window.

[0180] Option 4-2: Increase the length of the time window.

[0181] For example, when a delayed downlink transmission scheme is used when downlink transmission overlaps with non-downlink time (i.e., the first method in Embodiment 2 above), the downlink transmission may be delayed beyond the original time window, making it impossible for the transmission to be completed within the original time window. This problem may be solved by increasing the length of the time window. Assuming the original time window length is T, the method of increasing the length of the time window may include any one of the following (1) to (3): (1) Extend the length of the time window by a first duration, which is configured by the wireless communication node or predefined by the protocol, or is the transmission time required for the delayed transmission within the time window.

[0182] The time window length at this point is T+M. M may be configured on the network side or predefined by the standard. Alternatively, M may be the time required to complete the downlink transmission that was originally delayed within the time window.

[0183] (2) Expand the time window by a first factor, which is configured by the wireless communication node or predefined by the protocol, or is the ratio of the length of the periodic pattern to the transmission duration within the periodic pattern.

[0184] The time window length at this point is T*N. N may be configured on the network side or predefined by the standard. Alternatively, N=X / Y (or N=X / Y rounded up), where X is the length of the periodic pattern and Y is the downlink time length within one periodic pattern.

[0185] (3) Expand the time window by a first multiple and then extend the first duration.

[0186] The time window length at this time is T*N+M. N is defined as described in (2) above, and M is defined as described in (1) above.

[0187] Option 4-3: Delay the end time of the time window.

[0188] For example, the end time of the time window can be delayed to the time when the downlink transmission that originally started within the time window or the delayed downlink transmission is completed, or the end time of the last time unit of the downlink transmission that originally started within the time window or the delayed downlink transmission.

[0189] Option 4-4: Modify the definition of the length (or duration) of the time window.

[0190] When modifying the definition of the time window, it may include at least one of the following (1) and (2): (1) Time-domain resources that are not transmitted are not included in the length of the time window, or the length of the time window is defined based on the transmission time or the available transmission time.

[0191] Taking downlink transmission as an example, non-downlink time resources can be excluded from the duration / length of the time window. Alternatively, the length of the time window can be configured / defined based on downlink time or available downlink time (rather than absolute time). For example, the length of the time window can be the number of (available / valid) downlink superframes / system frames / subframes / slots. This can be applied to delayed downlink transmission (the first method in Embodiment 2 above), or to schemes where only downlink time is included in the downlink transmission mapping (the third method in Embodiment 2 above).

[0192] (2) The length of the time window is defined based on the periodic pattern length, or periodic pattern period, or transmission time period, or the number of available PDCCH detection opportunities.

[0193] For example, the unit of time window length is the periodic pattern length.

[0194] It should be noted that if the start time of the time window falls outside the downlink time period, the UE cannot start downlink reception in a timely manner, which may result in a wasted time window. Therefore, the start time of the time window may be delayed to improve efficiency. Additionally, when the end time of the time window falls outside the downlink time period, the end time can be moved forward to the end time of the last downlink segment. In this case, at least one of the following schemes 4-5 to 4-7 can be considered to reduce the effective time proportion of the time window.

[0195] Option 4-5: Delay the start time of the time window.

[0196] For example, if the start time of a time window falls within a non-downlink time period (or the first time unit of the time window overlaps with a non-downlink time period), then the start time (or the first time unit) of the time window is delayed to the next downlink time period, the next downlink time unit, or the first downlink time unit within the original time window, etc. Correspondingly, the end time of the time window may be delayed in the same way as the start time, or it may not be delayed.

[0197] Option 4-6: Set the end time of the time window in advance.

[0198] For example, if the end time of a time window falls within a non-downlink time period (or the last time unit of the time window overlaps with a non-downlink time period), then the end time (or last time unit) of the time window will be moved forward to the previous downlink time period, the previous downlink time unit, or the last downlink time unit within the original time window. Correspondingly, the start time of the time window may be moved forward in the same way as the end time, or it may not be moved forward at all.

[0199] Schemes 4-5 and 4-6 can be combined. For example, if both the start and end times are outside the downlink time window, the start time is delayed to the first downlink time unit within the original time window, and the end time is advanced to the last downlink time unit within the original time window.

[0200] Option 4-7: Time-domain resources that are not for transmission time are not used to determine the start time of a time window, or the start time of a time window is determined based on transmission time or available transmission time.

[0201] Taking downlink transmission as an example, time resources outside of downlink time periods may not be used in determining the start time of the time window. Alternatively, the configuration / definition of the start time of the time window may be based on downlink time or available downlink time (rather than absolute time). For example, when the start time of the time window is a PDCCH detection timing or a Searching Space (SS) timing, only timings within the downlink time period are used to determine the start time of the time window.

[0202] More specifically, for example, the RAR time window for Random Access Response (RAR) might begin at the earliest (Type-1) PDCCH detection opportunity / resource after the time unit (e.g., subframe, symbol) where the PRACH transmission ends, plus an offset time (e.g., 1 symbol, 3 subframes, round-trip time, or a combination of the above offsets). In this case, the start time might be modified to: the earliest available / valid / located in / overlapping with downlink time (Type-1) PDCCH detection opportunity / resource after the time unit (e.g., subframe, symbol) where the PRACH transmission ends, plus an offset time (e.g., 1 symbol, 3 subframes, round-trip time, or a combination of the above offsets).

[0203] It should be noted that the above-mentioned time window adjustment scheme may be used in combination with the scheme in Embodiment 2. For example, when downlink transmission overlaps with non-downlink time, if the system supports both delay and drop processing methods, different time window adjustment schemes may be used depending on the processing method. For example, for the drop processing scheme (the second method in Embodiment 2 above), a scheme that increases the time window length is adopted (Scheme 4-2 or Scheme 4-3 above); for the delay processing scheme (the first method in Embodiment 2 above), a scheme that keeps the time window length unchanged is adopted (Scheme 4-1); for the scheme that only includes downlink time resources in resource mapping (the third method in Embodiment 2 above), a scheme that only includes downlink time in the time window length is adopted (Scheme 4-4). The specific scheme used may be configured by the network side or predefined by the standard.

[0204] Furthermore, the aforementioned time window adjustment scheme can be applied not only to downlink transmission but also to uplink transmission.

[0205] Example 5: How a wireless communication device determines a timer when the transmission resources include a timer.

[0206] In some implementations, the wireless communication device determines the timer, which may include at least one of the following schemes 5-1 to 5-7: Option 5-1: Do not modify the timer definition or parameters.

[0207] For example, when a downlink transmission overlaps with a non-downlink transmission time and a scheme to discard downlink transmission is used (i.e., the second method in the above embodiment 2), the downlink transmission can be completed within the original timer.

[0208] Option 5-2: Increase the length of the timer.

[0209] For example, when a delayed downlink transmission scheme is used when downlink transmission overlaps with non-downlink time (i.e., the first method in Embodiment 2 above), the downlink transmission may be delayed beyond the original timer, making it impossible for the transmission to be completed within the original timer. This problem may be solved by increasing the timer length. Assuming the original timer length is T1, the method of increasing the timer length may include any one of the following (1) to (3): (1) Extend the length of the timer by a second duration, which is configured by the wireless communication node or predefined by the protocol, or is the transmission time required for the delayed transmission within the timer.

[0210] The timer length at this point is T1 + M1. M1 may be configured on the network side or predefined by the standard. Alternatively, M1 may be the time required to complete the downlink transmission that was originally delayed within the timer.

[0211] (2) Increase the timer by a second factor, which is configured by the wireless communication node or predefined by the protocol, or is the ratio of the length of the periodic mode to the transmission duration within the periodic mode.

[0212] The timer length at this point is T1*N1. N1 may be configured on the network side or predefined by the standard. Alternatively, N1=X1 / Y1 (or N1=X1 / Y1 rounded up), where X1 is the length of the periodic pattern and Y1 is the downlink time length within one periodic pattern.

[0213] (3) Increase the timer by a second multiple and then extend the duration by a second time.

[0214] The time window length at this time is T1*N1+M1. N1 is defined as described in (2) above, and M1 is defined as described in (1) above.

[0215] Option 5-3: Delay timer end time.

[0216] For example, the end time of the timer can be delayed until the time when the downlink transmission that originally started within the timer or the delayed downlink transmission is completed, or the end time of the last time unit of the downlink transmission that originally started within the timer or the delayed downlink transmission.

[0217] Solution 5-4: Modify the definition of the timer's length (or duration).

[0218] When modifying the definition of a timer, it may include at least one of the following (1) and (2): (1) Time-domain resources that are not transmitted are not included in the length of the timer, or the length of the timer is defined based on the transmission time or the available transmission time.

[0219] Taking downlink transmission as an example, non-downlink time resources can be excluded from the timer's duration / length. Alternatively, the timer's length can be configured / defined based on downlink time or available downlink time (rather than absolute time). For example, the timer's length can be the number of (available / valid) downlink superframes / system frames / subframes / slots. This can be applied to delayed downlink transmission (the first method in Embodiment 2 above), or to schemes where only downlink time is included in the downlink transmission mapping (the third method in Embodiment 2 above).

[0220] (2) The length of the timer is defined based on the periodic mode length, or periodic mode period, or transmission time period, or the number of available PDCCH detection opportunities.

[0221] For example, the unit of timer length is the periodic mode length.

[0222] It should be noted that if the timer's start / restart time falls outside the downlink time, the UE cannot start downlink reception in a timely manner, which may result in wasted time. Therefore, the timer's start / restart time may be delayed to improve efficiency. Additionally, when the timer's expiration / stop time falls outside the downlink time, the end time can be moved forward to the end time of the last downlink segment. In this case, at least one of the following schemes 5-5 to 5-7 can be considered to reduce the proportion of effective time for the timer.

[0223] Option 5-5: Delay the start / restart time of the timer.

[0224] For example, if the timer's start / restart time falls within a non-downlink time (or the timer's first time unit overlaps with a non-downlink time), the timer's start / restart time (or first time unit) is delayed to the next downlink time, the next downlink time unit, or the original first downlink time unit within the timer. Correspondingly, the timer's expiration / stop time may be delayed in the same way as the start / restart time, or it may not be delayed at all.

[0225] Option 5-6: Set the expiration / stop time of the timer in advance.

[0226] For example, if the timer's expiration / stop time falls within a non-downlink time (or the last time unit of the time window overlaps with a non-downlink time), the timer's expiration / stop time (or last time unit) will be advanced to the previous downlink time period, the previous downlink time unit, or the original last downlink time unit within the timer. Correspondingly, the timer's start / restart time may be advanced in the same way as the expiration / stop time, or it may not be advanced at all.

[0227] Schemes 5-5 and 5-6 above can be combined. For example, if the start / restart time and the expiration / stop time are both outside the downlink time, then the start / restart time is delayed to the first downlink time unit within the original timer, and the expiration / stop time is advanced to the last downlink time unit within the original timer.

[0228] Option 5-7: Time-domain resources that are not for transmission time are not used to determine the start / restart time of a timer, or the expiration / stop time of a timer is determined based on the transmission time or the available transmission time.

[0229] Taking downlink transmission as an example, time resources outside of downlink time periods may not be used in determining the timer's start time. Alternatively, the timer's start time configuration / definition may be based on downlink time or available downlink time (rather than absolute time). For instance, when the timer's start time is a PDCCH detection timing or a Searching Space (SS) timing, only timings within the downlink time period are used to determine the timer's start time.

[0230] It should be noted that the above-mentioned timer adjustment schemes may be used in combination with the schemes in Embodiment 2. For example, when downlink transmission overlaps with non-downlink time, if the system supports both delay and drop processing methods, different timer adjustment schemes may be used depending on the processing method. For example, for the drop processing scheme (the second method in Embodiment 2 above), a scheme that increases the timer length is adopted (Scheme 5-2 or Scheme 5-3 above); for the delay processing scheme (the first method in Embodiment 2 above), a scheme that keeps the timer length unchanged is adopted (Scheme 5-1); for the scheme that only includes downlink time resources in the resource mapping (the third method in Embodiment 2 above), a scheme that only includes downlink time in the timer length is adopted (Scheme 5-4). The specific scheme used may be configured by the network side or predefined by the standard.

[0231] Furthermore, the aforementioned timer adjustment scheme can be applied not only to downlink transmission but also to uplink transmission.

[0232] Example 6: How a wireless communication device determines paging resources when transmission resources include paging resources.

[0233] In some implementations, the wireless communication device determines the transmission resources, including at least one of the following schemes 6-1 to 6-4: Option 6-1: Determine resources that overlap with non-downlink times as invalid or unavailable paging resources, or determine resources that overlap with downlink times as valid or available paging resources.

[0234] When a paging resource (e.g., paging timing / paging frame / paging superframe) overlaps with a non-downlink time, the paging resource is invalid / unavailable. Alternatively, when a paging resource (e.g., paging timing / paging frame / paging superframe) overlaps with a downlink time, the paging resource is valid / available. The UE does not detect paging messages or paging message scheduling information on invalid / unavailable paging resources. Alternatively, the UE only detects paging messages or paging message scheduling information on valid / available paging resources. The network side may ensure that there is at least one valid / available paging resource within each system information modification period through configuration (e.g., T, nB, periodic pattern length, downlink time length, downlink time offset, etc.).

[0235] Option 6-2: Delay paging resources when paging resources overlap with non-downlink times.

[0236] When paging resources (e.g., paging timing / paging frame / paging superframe) overlap with non-downlink time, paging resources may be delayed. In the case of delayed paging resources, at least one of the following may be included: Delay paging resources to the next downlink time segment or the next downlink time unit; The portion of the paging resources that overlaps with non-downlink times will be delayed to the next downlink time segment or the next downlink time unit.

[0237] The downlink time unit includes at least one of superframe, frame, subframe, time slot, resource unit, transport block, repeated transmission, symbol, and millisecond. The next downlink time unit includes the next available or valid downlink time unit, or the next downlink time unit that does not overlap with other transmissions, or the next non-reserved downlink time unit, or the next first downlink time unit that spans multiple downlink time units.

[0238] It should be noted that when multiple paging resources are delayed, they can be delayed sequentially.

[0239] Option 6-3: Modify the method for determining paging resources.

[0240] When modifying the method for determining paging resources, at least one of the following (1) to (3) may be included: (1) Determine the paging resources based on additional wireless communication device identifiers or group identifiers. For example, an additional UE ID or group ID can be introduced to determine paging resources. For instance, a Group_ID can be introduced to replace the UE_ID in the PF or PO determination formula. The Group_ID may be predefined by the standard (e.g., Group_ID = UE_ID mod Ngroup, where Ngroup is the number of groups) or configured on the network side. UEs with different UE_IDs can correspond to the same Group_ID. In this way, paging opportunities for different UEs can be centralized.

[0241] (2) Determine paging resources based on additional offsets.

[0242] For example, the SFN obtained from the PF determination formula, plus an offset X, becomes the paging frame PF. X may be predefined by the standard or configured on the network side, for example, equal to the offset between the first downlink time segment within the superframe and the start time of the superframe. In this way, the paging timing can be shifted into the downlink time.

[0243] (3) Change the paging cycle value.

[0244] For example, the unit of paging cycle is the length of the cycle pattern.

[0245] Option 6-4: The method for determining paging resources remains unchanged (i.e., paging resources are determined in the traditional way regardless of whether it is a non-downlink time). If the PDCCH transmission starting from the paging time overlaps with a non-downlink time, it is delayed, for example... Figure 15 As shown in Figure 16. Specific delay schemes are as shown in Embodiment 2, such as the first method in Embodiment 2. Alternatively, PDCCH transmissions starting from the paging time may be discarded if they overlap with non-downlink times, as shown in Figure 16. Specific discarding schemes are as shown in Embodiment 2, such as the second method in Embodiment 2.

[0246] It should be noted that the above schemes 6-1 to 6-4 can be used in combination. For example, a group ID can be introduced, along with an additional offset, to centralize the paging opportunities of all UEs and offset them into the downlink time.

[0247] Example 7: How a wireless communication device determines a random access opportunity when transmission resources include random access opportunities.

[0248] In some implementations, the wireless communication device determines the timing of random access, including at least one of the following schemes 7-1 to 7-4: Option 7-1: Determine resources that overlap with non-uplink times as invalid or unavailable random access opportunities, or determine resources that overlap with uplink times as valid or available random access opportunities.

[0249] When a random access opportunity overlaps with a non-uplink time, that random access opportunity is invalid / unavailable. Alternatively, when a random access opportunity overlaps with an uplink time, that random access opportunity is valid / available. The UE does not perform random access operations on invalid / unavailable random access opportunities. Alternatively, the UE only performs random access operations on valid / available random access opportunities. The network side may configure parameters (e.g., T, nB, periodic pattern length, downlink time length, downlink time offset, etc.) to ensure that there is at least one valid / available random access opportunity within each system information modification period.

[0250] Option 7-2: Delay the random access timing when the random access timing overlaps with the non-uplink timing.

[0251] In cases where the timing of random access is delayed, at least one of the following may be included: The random access timing will be delayed to the next uplink time segment or the next uplink time unit; The portion of the random access timing that overlaps with non-uplink times is delayed to the next uplink time segment or the next uplink time unit.

[0252] The uplink time unit includes at least one of superframe, frame, subframe, time slot, resource unit, transport block, repeated transmission, symbol, and millisecond. The next uplink time unit includes the next available or valid uplink time unit, or the next uplink time unit that does not overlap with other transmissions, or the next non-reserved uplink time unit, or the next first uplink time unit that spans multiple uplink time units.

[0253] It should be noted that when multiple random access opportunities are delayed, they can be delayed sequentially.

[0254] Option 7-3: Modify the method for determining the timing of random access.

[0255] When modifying the method for determining the timing of random access, it may include at least one of the following (1) to (3): (1) Determine the timing of random access based on additional wireless communication device identifiers or group identifiers.

[0256] For example, an additional UE ID or group ID can be introduced to determine the random access timing. For instance, a Group_ID can be introduced instead of the UE_ID in the random access timing formula. The Group_ID may be predefined by a standard (e.g., Group_ID = UE_ID mod Ngroup, where Ngroup is the number of groups) or configured on the network side. UEs with different UE_IDs can correspond to the same Group_ID. In this way, the random access timings of different UEs can be centralized.

[0257] (2) Determine the timing of random access based on the additional offset.

[0258] For example, the random access timing obtained from the formula is adjusted by adding an offset X to arrive at the final random access timing. X may be predefined by the standard or configured on the network side, for example, equal to the offset between the first uplink time segment within the superframe and the start time of the superframe. In this way, the random access timing can be offset to the uplink time segment.

[0259] (3) Change the value of the random access timing.

[0260] For example, the unit of random access period is the length of the periodic pattern.

[0261] Option 7-4: The method for determining the random access timing remains unchanged (i.e., the random access timing is determined using the traditional method regardless of whether it is a non-uplink time). PRACH transmissions starting from the random access timing are delayed if they overlap with non-uplink times. Specific delay schemes are shown in Example 2, such as the first method in Example 2. Alternatively, PRACH transmissions starting from the random access timing are discarded if they overlap with non-uplink times. Specific discarding schemes are shown in Example 2, such as the second method in Example 2.

[0262] It should be noted that the above schemes 7-1 to 7-4 can be used in combination. For example, a group ID can be introduced, along with an additional offset, to centralize and offset the random access opportunities of all UEs into the uplink time.

[0263] Example 8: How a wireless communication device determines the transmission resources for warning information when the transmission resources include those for warning information. It is worth noting that the warning indication-related schemes or enhancements in this application embodiment may only be applied under specific circumstances. These specific circumstances may include at least one of the following: the UE has the capability for warning indication or warning service; the network side enables / activates warning indication or warning service; the UE reports the capability or requirement for warning indication or warning service; the UE is in a connected state; the UE is in an idle state; the UE is in an inactive state; the UE receives an indication warning occurring, or within a certain frequency range.

[0264] When warning indication is supported in NTN, warning information can be indicated by at least one of the following schemes 8-1 to 8-5: Option 8-1: Warning messages are indicated via the media access control unit MAC CE.

[0265] Specifically, a MAC CE can be defined for warning indication, which indicates warning information via a MAC PDU or MAC subheader. The warning information may include at least one of the following: the type of warning, the source of the warning, or whether a warning (or not) occurred. The MAC subheader may be assigned a corresponding LCID. The transmission of a MAC CE or MAC subheader may indicate the occurrence of a warning. The MAC PDU may indicate other warning information, such as the type of warning, its source, etc.

[0266] Option 8-2: Indicate warning information through system message block SIBx (x>=1).

[0267] Specifically, a system message block (SIBx) can be defined to indicate warning information. Warning information may include at least one of the following: the type of warning, the source of the warning, or whether a warning (or not) occurred. Examples include pws-indication, etws-Indication, and cmas-Indication.

[0268] Option 8-3: Indicate warning messages via paging.

[0269] When a warning message is indicated via paging, at least one of the following schemes 8-3-1 to 8-3-3 may be included: Option 8-3-1: Warning information is indicated via paging downlink control information (DCI).

[0270] Paging DCI may include at least one of the following: DCI format N2; Cyclic Redundancy Check (CRC) is a DCI scrambled by P-RNTI; The CRC is a DCI scrambled by P-RNTI and directly indicated; the DCI can be a DCI with the "Paging / Direct Indication" distinguishing identifier set to 0, or a DCI with the "Paging / Direct Indication" distinguishing identifier indicating that the DCI is used for "Direct Indication"; DCI format used to indicate warnings (newer DCI formats, such as format N3).

[0271] When indicating a warning message in a paging DCI, it may be done by using reserved information bits, or by multiplexing or reinterpreting one or more bits in an existing bit field (such as Direct Indication information), or one or more states.

[0272] Scheme 8-3-2: Paging messages or narrowband physical downlink shared channel (NPDSCH) are scheduled via paging DCI. The paging message or NPDSCH is used to indicate warning information (as in Scheme 8-2).

[0273] Paging DCI may include at least one of the following: DCI format N2; CRC is a DCI scrambled by P-RNTI; The CRC is scrambled by P-RNTI and is used for paging DCI; the paging DCI may have a "Paging / Direct Indication" distinguishing identifier of 1 in the DCI, or the "Paging / Direct Indication" distinguishing identifier indicates that the DCI is used for "paging"; DCI format used to indicate warnings (newer DCI formats, such as format N3).

[0274] Option 8-3-3: Paging messages or NPDSCH are scheduled through paging DCI. Paging DCI is used to indicate that a warning has occurred, and paging messages or NPDSCH are used to indicate warning information (as in Option 8-2).

[0275] Paging DCI may include at least one of the following: DCI format N2; CRC is a DCI scrambled by P-RNTI; The CRC is scrambled by P-RNTI and is used for paging DCI; the paging DCI may have a "Paging / Direct Indication" distinguishing identifier of 1 in the DCI, or the "Paging / Direct Indication" distinguishing identifier indicates that the DCI is used for "paging"; In practical implementation, the UE may determine whether a warning message or NPDSCH contains warning information based on the indication in the paging DCI. The UE may determine the priority of the paging message or NPDSCH or the UE behavior based on whether a warning has occurred. The indication in the paging DCI of whether a warning has occurred may be achieved by multiplexing or reinterpreting one or more bits in existing bit fields (such as resource assignment, modulation and coding scheme, repetition number, DCI subframe repetition number), or one or more states.

[0276] Option 8-4: Indicate whether a warning has occurred via paging, and indicate the warning information via SIBx (as in Option 8-2).

[0277] When indicating whether a warning has occurred via paging and indicating a warning message via SIBx, at least one of the following schemes 8-4-1 to 8-4-4 may be included: Option 8-4-1: Indicate whether a warning has occurred via paging DCI, and indicate the warning information via SIBx.

[0278] Paging DCI may include at least one of the following: DCI format N2; CRC is a DCI scrambled by P-RNTI; The CRC is a DCI scrambled by P-RNTI and directly indicated; the DCI can be a DCI with the "Paging / Direct Indication" distinguishing identifier set to 0, or a DCI with the "Paging / Direct Indication" distinguishing identifier indicating that the DCI is used for "Direct Indication"; DCI format used to indicate warnings (newer DCI formats, such as format N3).

[0279] When a warning (or not) occurs in the paging DCI, it may be indicated by using reserved information bits, or by multiplexing or reinterpreting one or more bits in an existing bit field (such as Direct Indication information), or by one or more states. When a paging DCI indicates that a warning has occurred, the UE detects the SIBx indicating the warning information.

[0280] Option 8-4-2: The warning (whether) occurs is indicated by paging DCI, and the warning information is indicated by SIBx. SIBx is scheduled by SIB1-NB.

[0281] Paging DCI may include at least one of the following: DCI format N2; CRC is a DCI scrambled by P-RNTI; The CRC is a DCI scrambled by P-RNTI and directly indicated; the DCI can be a DCI with the "Paging / Direct Indication" distinguishing identifier set to 0, or a DCI with the "Paging / Direct Indication" distinguishing identifier indicating that the DCI is used for "Direct Indication"; DCI format used to indicate warnings (newer DCI formats, such as format N3).

[0282] When a warning is indicated in the paging DCI, it may be done by using reserved information bits, or by multiplexing or reinterpreting one or more bits in an existing bit field (such as Direct Indication information), or by one or more states. When a warning is indicated in the paging DCI, the UE detects the SIB1-NB and (based on the scheduling information of SIBx in the SIB1-NB) detects the SIBx indicating the warning information.

[0283] Option 8-4-3: Indicate whether a warning has occurred via paging messages, and indicate the warning information via SIBx.

[0284] The paging message may be as described in scheme 8-3-2. When a paging message indicates a warning, the UE detects the SIBx indicating the warning message.

[0285] Option 8-4-4: Indicate whether a warning has occurred via paging messages, and indicate the warning information via SIBx. SIBx is scheduled via SIB1-NB.

[0286] The paging message may be as described in scheme 8-3-2. When a paging message indicates a warning, the UE detects the SIB1-NB and (based on the scheduling information of SIBx in the SIB1-NB) detects the SIBx indicating the warning message.

[0287] Option 8-5: Enable signaling, used to indicate whether warning messages are enabled.

[0288] For warning message indication, enabling signaling / indication may be introduced. For example, signaling (such as MIB / PBCH / SIB1) may indicate whether or not warning message indication is enabled. The scheme or behavior of the UE in determining the time-domain resources of warning messages in the embodiments of this application may only be applied when warning message indication is enabled. If warning message indication is not enabled, conventional UE behavior is used. Specifically, for example: The UE will only receive SIBx if the warning message indication is enabled; When the warning message indicator is enabled, the detection of the paging PDCCH is not affected by DRX; When the warning message indication is enabled, paging detection has a higher priority.

[0289] Furthermore, corresponding UE capabilities may be introduced for warning information indication. For example, Public Warning System (PWS) capability, Earthquake and Tsunami Warning System (ETWS) capability, or Commercial Mobile Alert System (CMAS) capability. The scheme or behavior of the UE determining the time-domain resources for warning information in the embodiments of this application may only be effective or used by UEs with the corresponding capabilities. If the UE does not have the corresponding capabilities, conventional UE behavior will be used.

[0290] Since warnings can occur at any time, there is a possibility that the warning indication (which may include at least one of the above-mentioned SIBx, paging DCI, and paging messages) may conflict with other configurations, for example: Warning indications overlap with non-downlink times. For example, in IoT-NTN TDD mode, they overlap with non-downlink times.

[0291] The warning indicates that the timing resources overlap with other downlink transmissions. For example, the warning occurs when an NPDSCH is being transmitted repeatedly.

[0292] The warning indicates that it occurred during DRX inactivity. For example, if the HARQ RTTtimer corresponding to all HARQ processes is running, the warning will occur.

[0293] To address the aforementioned conflicts, it may be necessary to enhance the UE behavior.

[0294] In some implementations, when enhancing UE behavior, at least one of the following schemes 8-6 to 8-12 may be considered, that is, when the UE determines the temporal domain resources for the warning information, it may include at least one of the following schemes 8-6 to 8-12: Option 8-6: Detect and receive SIBx within the time window of SIBx. Alternatively, always detect and receive SIBx within the time window of SIBx. Alternatively, detect and receive SIBx at least once within the time window of any SIBx during a paging cycle.

[0295] When detecting and receiving SIBx within the SIBx time window, further UE behaviors may be considered to avoid conflicts with other transmissions within the window. The UE behaviors considered in this scheme may only be applied if at least one of the following conditions is met: the UE has warning indication or warning service capabilities, the network side enables / activates warning indication or warning service, or the UE receives an indication warning. In some implementations, at least one of the following (1) to (5) may be included: (1) Downlink time-domain resources of SIBx or (downlink) subframes containing SIBx are not included in or used in resource mapping for other downlink transmissions.

[0296] (2) During the paging-triggered SI acquisition process, or after the UE receives an indication warning, or after the UE receives an indication warning but has not yet received the SIBx containing the warning information, the UE is not required or expected to detect or receive downlink transmissions / PDSCH / PDCCH that overlap with the downlink time domain resources of the SIBx. The downlink transmission may be a PDSCH scrambled with C-RNTI, PUR-RNTI, or CS-RNTI. Alternatively, during the paging-triggered SI acquisition process, or after the UE receives an indication warning, or after the UE receives an indication warning but has not yet received the SIBx containing the warning information, the UE is not required or expected to send uplink transmissions that overlap with the downlink time domain resources of the SIBx.

[0297] (3) During the paging-triggered SI acquisition process, or after the UE receives an indication warning, or after the UE receives an indication warning but has not yet received the SIBx containing the warning information, the UE may receive the SIBx on another carrier or frequency domain resource while receiving the downlink transmission / PDSCH / PDCCH. The downlink transmission may be a PDSCH scrambled with C-RNTI, PUR-RNTI, or CS-RNTI.

[0298] (4) If the downlink time resources of SIBx overlap with the downlink time resources of other downlink transmissions, discard or delay other downlink transmissions.

[0299] The term "dropping or delaying other downlink transmissions" here may refer to dropping or delaying the entire downlink transmission (including all duplicate transmissions or time resources), dropping or delaying downlink transmissions that overlap with SIBx (referring to duplicate transmissions that overlap with SIBx in downlink duplicate transmissions), or dropping or delaying portions of downlink transmissions that overlap with SIBx (referring to the portion of downlink transmissions that overlap with SIBx in time resources in downlink transmissions).

[0300] (5) In cases where the downlink time resources of SIBx overlap with the uplink time resources of uplink transmission (possibly after considering the impact of TA), cancel or delay the uplink transmission.

[0301] The cancellation or delay of uplink transmission here may refer to the cancellation or delay of the entire uplink transmission (including all duplicate transmissions or time resources), or it may refer to the cancellation or delay of uplink transmissions that overlap with SIBx (referring to duplicate transmissions that overlap with SIBx in uplink duplicate transmissions), or it may refer to the discarding or delay of uplink transmission portions that overlap with SIBx (referring to uplink transmission portions that overlap with SIBx in time resources in uplink transmissions).

[0302] (6) In the case where the downlink time resources of SIBx overlap with non-downlink time, delay SIBx, discard SIBx, or do not use the downlink time resources of SIBx in the resource mapping of downlink transmission.

[0303] In cases where SIBx is delayed, discarded, or its downlink time resources are not used in the resource mapping for downlink transmissions, the specific implementation methods can be found in the corresponding content of Embodiment 2 above, and will not be repeated here. It is worth noting that SIBx may be processed differently from other downlink transmissions. For example, downlink transmission may be delayed when SIBx overlaps with non-downlink time, and downlink transmission may be discarded when other downlink transmissions overlap with non-downlink time.

[0304] (7) When the SIBx time window overlaps with a non-downlink time, increase the length of the SIBx time window, delay the end time of the SIBx time window, modify the definition of the length of the SIBx time window, delay the start time of the SIBx time window, advance the end time of the SIBx time window, or do not use non-transmission time time domain resources to determine the start time of the SIBx time window, or determine the start time of the SIBx time window based on the transmission time or the available transmission time.

[0305] When the SIBx time window overlaps with a non-downlink time, the specific implementation of this processing method can be found in the corresponding content of Embodiment 4 above. It is worth noting that the SIBx time window may be processed differently from other time windows. For example, when the SIBx time window overlaps with a non-downlink time, the end time of the time window may be delayed, while other SIB time windows may not be modified when they overlap with non-downlink time.

[0306] Option 8-7: Detect the PDCCH in the paging common search space or at the paging time. Alternatively, always detect the PDCCH in the paging common search space or at the paging time. Alternatively, detect the PDCCH at least once in any paging common search space or at any paging time during the paging cycle.

[0307] The UE detects the PDCCH on the paging common search space or at the paging time. To address conflicts between the paging PDCCH (which may refer to the PDCCH containing the paging DCI, or the PDCCH at the start of the paging time, or the PDCCH corresponding to the P-RNTI, or the paging time, or the common search space (time), or the common search space available for paging (time), or the Type-1 NPDCCH common search space (time)) and other transmissions, further UE behaviors may be considered. In some implementations, at least one of the following (1) to (7) may be included: (1) Downlink time-domain resources for paging PDCCH or (downlink) subframes containing paging PDCCH are not included in or used in resource mapping for other downlink transmissions. Alternatively, paging timing / paging frame / search space for paging / Type-1 NPDCCH common search space are not included in or used in resource mapping or transmission for PDSCH / NRS / other search spaces / other PDCCHs.

[0308] (2) If the downlink time resources of the paging PDCCH overlap with the downlink time resources of other downlink transmissions, discard or delay the other downlink transmissions.

[0309] The term "discarding or delaying other downlink transmissions" here may refer to discarding or delaying the entire downlink transmission (including all duplicate transmissions or time resources), or it may refer to discarding or delaying downlink transmissions that overlap with the paging PDCCH (referring to duplicate transmissions that overlap with the paging PDCCH in downlink duplicate transmissions), or it may refer to discarding or delaying portions of downlink transmissions that overlap with the paging PDCCH (referring to the portion of downlink transmissions that overlap with the paging PDCCH in time resources in downlink transmissions).

[0310] (3) In cases where the downlink time resources of paging PDCCH overlap with the uplink time resources of uplink transmission (possibly after considering the impact of TA), cancel or delay the uplink transmission.

[0311] The cancellation or delay of uplink transmission here may refer to canceling / delaying the entire uplink transmission (including all duplicate transmissions or time resources), or it may refer to canceling or delaying uplink transmissions that overlap with the paging PDCCH (referring to duplicate transmissions that overlap with the paging PDCCH in uplink duplicate transmissions), or it may refer to discarding or delaying the portion of uplink transmission that overlaps with the paging PDCCH (referring to the portion of uplink transmission that overlaps with the paging PDCCH in time resources in uplink transmission).

[0312] For example, (when the warning indication function is enabled, or when the UE has warning indication capabilities) on the subframe where the Type-1 NPDCCH common search space is located, or on the subframe where the NPDSCH scheduled by the P-RNTI scrambled DCI CRC NPDCCH is located, or (considering timing advance) on the uplink subframe that overlaps with the downlink subframe where the Type-1 NPDCCH common search space is located, or (considering timing advance) on the uplink subframe that overlaps with the downlink subframe where the NPDSCH scheduled by the P-RNTI scrambled DCI CRC NPDCCH is located, the UE does not need to send NPUSCH, or the UE does not need to send NPRACH, or the UE does not need to send uplink transmissions. For example, (when the warning indication function is enabled, or when the UE has warning indication capabilities) if the NPUSCH / NPRACH transmission (after considering timing advance) overlaps with the subframe where the (UE-detected) Type-1 NPDCCH common search space is located, or (after considering timing advance) overlaps with the subframe where the NPDSCH scheduled by the P-RNTI scrambled DCI CRC NPDCCH is located, then the NPUSCH / NPRACH transmission, or the overlapping portion of the NPUSCH / NPRACH transmission, is discarded.

[0313] (4) In cases where downlink time resources for paging PDCCH overlap with uplink time resources for uplink transmission (possibly after considering the impact of TA), the transmission or detection of PDCCH will be delayed to the next uplink interval (UL gap). The UE can detect PDCCH within the UL gap.

[0314] (5) When receiving PDSCH, NRS or other PDCCH or sending PUSCH or PRACH, detect or receive PDCCH.

[0315] In other words, it allows the UE to detect / receive (paging) PDCCH when receiving PDSCH / NRS / other PDCCH or sending PUSCH / PRACH.

[0316] The current protocol imposes a series of constraints on when a UE receives downlink transmissions, specifying when the UE does not need to detect the PDCCH or PDSCH. Exceptions may be defined for paging PDCCH. These exceptions may be handled by adding general statements to the protocol. For example, at least one of the following (5a) to (5e) could be considered: (5a) When the UE does not need to detect the NPDCCH (when the warning indication function is enabled, or when the UE has the warning indication capability), the NPDCCH for paging PDCCH, or the NPDCCH for the paging timing of the UE in the Type-1 common search space is an exception.

[0317] (5b) (When the warning indication function is enabled, or when the UE has the warning indication capability), the UE always needs to detect the paging PDCCH, or the Type-1 common search space, or the NPDCCH in the Type-1 common search space corresponding to the paging time of the UE.

[0318] Alternatively, for each UE that does not need to detect the PDCCH, a separate explanation can be provided, indicating that the paging PDCCH is not effective. Specifically, for example: (5c) When the UE receives the NPDSCH scheduled in DCI format N1, the UE does not need to detect the NPDCCH between the start time of the NPDSCH and the HARQ-ACK feedback time. For example, as described in the following protocol:

[0319] To ensure the UE receives paging messages promptly, the constraints can be modified. For example, (when the warning indication function is enabled, or the UE has warning indication capabilities) the UE does not need to detect NPDCCHs other than the paging PDCCH between the start time of the NPDSCH and the feedback time of the HARQ-ACK. Specifically, "not required to monitor NPDCCH" can be modified to "not required to monitor NPDCCH except NPDCCH candidates of a Type1-NPDCCH common search space", or "not required to monitor NPDCCH except NPDCCH candidates of a Type1-NPDCCH common search space starting from pagingoccasion", or "not required to monitor NPDCCH candidates of a Type1A-NPDCCH common search space, a Type2-NPDCCH common search space, a Type2A-NPDCCH common search space, or a UE-specific NPDCCH search space".

[0320] (5d) In the subframe where the NPDSCH scheduled by the NPDCCH with Type-1 NPDCCH common search space or P-RNTI scrambled DCI CRC is located, the UE does not need to detect the NPDSCH scheduled by the NPDCCH with SC-RNTI or G-RNTI scrambled DCI CRC. For example, as described in the following protocol:

[0321] To ensure the UE can receive paging messages promptly, the constraints can be modified. For example, (when the warning indication function is enabled, or the UE has warning indication capabilities), on the subframe where the NPDSCH scheduled by the NPDCCH with DCI CRC scrambled by SC-RNTI or G-RNTI resides, the UE does not need to detect (other) NPDSCH, or does not need to detect (other) NPDCCH scheduled by NPDCCH. Specifically, change "not required to receive NPDSCH assigned by NPDCCH with DCI CRC scrambled by SC-RNTI or G-RNTI" to "not required to receive NPDSCH", or "not required to receive NPDSCH assigned by NPDCCH".

[0322] (5e) During PUR transmission, or when the UE detects the NPDCCH search space corresponding to PUR-RNTI, the UE does not need to detect the Type-1 common search space. For example, as described in the following protocol:

[0323] To ensure the UE can receive paging messages promptly, the constraints can be modified. For example, when the warning indication function is not enabled, or the UE lacks warning indication capabilities, the UE does not need to detect the Type-1 common search space during PUR transmission or when the UE detects the NPDCCH search space corresponding to PUR-RNTI. Specifically, the condition "If UE is not capable of PWS" or "If UE is not configured with PWS-Rx" can be added to the above protocol, where PWS-enable may be a signaling indicating that PWS is enabled, or a signaling indicating PWS-related configuration.

[0324] (6) When the downlink time resources of the paging PDCCH overlap with non-downlink time resources, the paging PDCCH is not detected on the overlapping resources, or the paging PDCCH is delayed, or the paging PDCCH is discarded, or the downlink time resources of the paging PDCCH are not used in the resource mapping of downlink transmission, or the method of determining the paging PDCCH is modified. When the downlink time resources of the paging PDCCH overlap with the non-downlink time resources, the specific implementation of this processing method can be found in the corresponding content of Embodiments 2 and 6 above.

[0325] (7) Restrict resource scheduling.

[0326] Under resource-constrained scheduling, overlap between paging PDCCH and other downlink transmissions can be avoided. For example, when scheduling NPDSCH transmissions, the network can prevent NPDSCH from overlapping with paging timings / paging frames / search spaces used for paging. Alternatively, the UE may not expect to receive PDSCH / NRS / other PDCCH / other transmissions during paging timings / paging frames / search spaces used for paging.

[0327] Option 8-8: Detect the PDCCH in the paging common search space or at the paging time and receive the paging message according to the paging DCI schedule. Alternatively, always detect the warning indication or paging message in the paging common search space or at the paging time. Alternatively, detect the warning indication or paging message at least once in any paging common search space or at any paging time during the paging cycle.

[0328] The UE detects the PDCCH in the paging common search space or at the paging time. Furthermore, the UE receives the paging message according to the paging DCI schedule. To address conflicts between the paging message and other transmissions, further UE behaviors may be considered. In some implementations, at least one of the following (1) and (2) may be included: (1) Prioritize receiving paging messages.

[0329] When paging messages are received first, at least one of the following (1a) to (1d) is specifically included: (1a) Downlink time-domain resources of paging messages (which may refer to PDSCH scheduled by paging DCI or NPDSCH scheduled by P-RNTI scrambled DCI CRC NPDCCH) or (downlink) subframes containing paging messages are not included in or used in resource mapping for other downlink transmissions.

[0330] (1b) In cases where the downlink time resources of a paging message overlap with the downlink time resources of other downlink transmissions, discard or delay the other downlink transmissions.

[0331] The term "discarding or delaying other downlink transmissions" here may refer to discarding or delaying the entire downlink transmission (including all duplicate transmissions or time resources), or it may refer to discarding or delaying downlink transmissions that overlap with paging messages (referring to duplicate transmissions that overlap with paging messages in downlink duplicate transmissions), or it may refer to discarding or delaying portions of downlink transmissions that overlap with paging messages (referring to the portion of downlink transmissions that overlap with paging messages in time resources in downlink transmissions).

[0332] (1c) In cases where the downlink time resources of a paging message overlap with the uplink time resources of an uplink transmission (possibly after taking TA into account), the uplink transmission may be cancelled or delayed.

[0333] The cancellation or delay of uplink transmission here may refer to the cancellation or delay of the entire uplink transmission (including all duplicate transmissions or time resources), or it may refer to the cancellation or delay of uplink transmissions that overlap with paging messages (referring to duplicate transmissions that overlap with paging messages in uplink duplicate transmissions), or it may refer to the discarding or delay of uplink transmission portions that overlap with paging messages (referring to uplink transmission portions that overlap with paging messages in time resources in uplink transmissions).

[0334] (1d) In the case where the downlink time resources of the paging message overlap with the non-downlink time resources, the paging message is not detected on the overlapping resources, or the paging message is delayed, or the paging message is discarded, or the downlink time resources of the paging message are not used in the resource mapping of downlink transmission, or the method of determining the paging message is modified.

[0335] When the downlink time resources of a paging message overlap with non-downlink time resources, the processing scheme here can be found in the corresponding content of Embodiments 2 and 6 above. It is worth noting that paging messages may be processed differently from other downlink transmissions. For example, downlink transmission may be delayed when paging messages overlap with non-downlink time resources, and downlink transmissions may be discarded when other downlink transmissions overlap with non-downlink time resources.

[0336] (2) If a warning is indicated in the paging DCI, the paging message shall be received first; otherwise, the paging message shall have the same priority as other downlink transmissions.

[0337] In cases where a warning is indicated in the paging DCI and paging messages are received preferentially, at least one of the following (2a) to (2d) may be included: (2a) Downlink time-domain resources containing paging messages (which may refer to the corresponding paging DCI indicating that a warning has occurred) or (downlink) subframes containing paging messages containing warning information are not counted or used in resource mapping for other downlink transmissions.

[0338] (2b) If the downlink time resources of a paging message containing a warning message overlap with the downlink time resources of other downlink transmissions, discard or delay the other downlink transmissions.

[0339] The term "discarding or delaying other downlink transmissions" here may refer to discarding or delaying the entire downlink transmission (including all duplicate transmissions or time resources), or it may refer to discarding or delaying downlink transmissions that overlap with paging messages containing warning information (referring to duplicate transmissions in downlink transmissions that overlap with paging messages containing warning information), or it may refer to discarding or delaying portions of downlink transmissions that overlap with paging messages containing warning information (referring to portions of downlink transmissions in downlink transmissions that overlap with paging messages containing warning information on time resources).

[0340] (2c) In cases where the downlink time resources of a paging message containing a warning message overlap with the uplink time resources of an uplink transmission (possibly after taking TA effects into account), the uplink transmission may be canceled or delayed.

[0341] The cancellation or delay of uplink transmission here may refer to the cancellation or delay of the entire uplink transmission (including all duplicate transmissions or time resources), or it may refer to the cancellation or delay of uplink transmissions that overlap with paging messages containing warning information (referring to duplicate transmissions in uplink transmissions that overlap with paging messages containing warning information), or it may refer to the discarding or delay of uplink transmission portions that overlap with paging messages containing warning information (referring to uplink transmission portions in uplink transmissions that overlap with paging messages containing warning information on time resources).

[0342] (2d) In the case where the downlink time resource of the paging message containing warning information overlaps with the non-downlink time resource, the paging message containing warning information is not detected on the overlapping resource, or the paging message containing warning information is delayed, or the paging message containing warning information is discarded, or the downlink time resource of the paging message containing warning information is not used in the resource mapping of downlink transmission, or the method of determining the paging message containing warning information is modified.

[0343] When the downlink time resources of a paging message containing warning information overlap with non-downlink time resources, the processing method here can be found in the corresponding content of Embodiments 2 and 6 above. It is worth noting that paging messages containing warning information may be processed differently from other downlink transmissions. For example, when a paging message containing warning information overlaps with a non-downlink time, the downlink transmission may be delayed; when other downlink transmissions overlap with a non-downlink time, the downlink transmission may be discarded.

[0344] Scheme 8-9: Detect the PDCCH in the paging common search space or at the paging time and determine the reception of SIBx according to the instructions of the paging DCI.

[0345] The UE detects the PDCCH in the paging public search space or at the paging time. Furthermore, the UE determines SIBx reception based on the paging DCI indication. For example, if a paging DCI indication warning occurs, the UE receives SIBx (within the SIBx time window); otherwise, the UE does not receive SIBx (within the SIBx time window). The UE's reception of the paging DCI can be referenced in scheme 8-7. When the UE receives SIBx, its behavior can be referenced in scheme 8-6.

[0346] Scheme 8-10: Detect the PDCCH in the paging common search space or at the paging time and receive the paging message according to the paging DCI schedule, and determine the reception of SIBx according to the indication of the paging message.

[0347] The UE detects the PDCCH in the paging common search space or at the paging time. The UE receives the paging message according to the paging DCI schedule. Then, the UE determines whether to receive SIBx based on the indication of the paging message. For example, if the paging message indicates a warning, the UE receives SIBx (within the SIBx time window); otherwise, the UE does not receive SIBx (within the SIBx time window). The UE's reception of the paging message can be referenced in scheme 8-8. When the UE receives SIBx, its behavior can be referenced in scheme 8-6.

[0348] Option 8-11: Detect the PDCCH in the paging common search space or at the paging time and determine the reception of SIB1-NB and SIBx according to the instructions of the paging DCI.

[0349] The UE will detect the PDCCH in the paging public search space or at the paging time. Furthermore, the UE will determine the reception of SIB1-NB and SIBx according to the paging DCI indication. For example, when a paging DCI indication warning occurs, the UE will first receive / detect SIB1-NB, and then receive SIBx according to the SIB1-NB's scheduling information (within the SIBx time window). The UE's reception of the paging DCI can refer to scheme 8-7. When the UE receives SIBx, its behavior can refer to scheme 8-6. The UE's reception of the SIB1-NB may consider at least one of the following (1) to (4): (1) Downlink time domain resources of SIB1-NB or (downlink) subframes containing SIB1-NB are not included in or used in resource mapping for other downlink transmissions.

[0350] (2) In cases where the downlink time resources of SIB1-NB overlap with the downlink time resources of other downlink transmissions, discard or delay other downlink transmissions.

[0351] The term "dropping or delaying other downlink transmissions" here may refer to dropping or delaying the entire downlink transmission (including all duplicate transmissions or time resources), dropping or delaying downlink transmissions that overlap with SIB1-NB (referring to duplicate transmissions that overlap with SIB1-NB in ​​downlink duplicate transmissions), or dropping or delaying portions of downlink transmissions that overlap with SIB1-NB (referring to the portion of downlink transmissions that overlap with SIB1-NB in ​​time resources in downlink transmissions).

[0352] (3) In cases where the downlink time resources of SIB1-NB overlap with the uplink time resources of uplink transmission (possibly after considering the impact of TA), the uplink transmission may be canceled or delayed.

[0353] Cancellation or delay here may refer to canceling or delaying the entire uplink transmission (including all duplicate transmissions or time resources), or it may refer to canceling or delaying uplink transmissions that overlap with SIB1-NB (referring to duplicate transmissions that overlap with SIB1-NB in ​​uplink duplicate transmissions), or it may refer to discarding or delaying the portion of uplink transmissions that overlap with SIB1-NB (referring to the portion of uplink transmissions that overlap with SIB1-NB in ​​time resources in uplink transmissions).

[0354] (4) In the case where the downlink time resources of SIB1-NB overlap with non-downlink time, delay SIB1-NB, discard SIB1-NB, or do not use the downlink time resources of SIB1-NB in ​​the resource mapping for downlink transmission.

[0355] When the downlink time resources of SIB1-NB overlap with non-downlink time resources, the handling method here can be found in the corresponding content of the above embodiment two.

[0356] Scheme 8-12: Detect the PDCCH in the paging common search space or at the paging time and receive the paging message according to the paging DCI schedule, and determine the reception of SIB1-NB and SIBx according to the indication of the paging message.

[0357] The UE detects the PDCCH in the paging common search space or at the paging time. The UE receives the paging message according to the paging DCI scheduling. Then, the UE determines the reception of SIB1-NB and SIBx based on the indication of the paging message. For example, when the paging message indicates a warning, the UE first receives / detects SIB1-NB, and then receives SIBx according to the SIB1-NB scheduling information (within the SIBx time window). The UE's reception of the paging message can refer to scheme 8-8. When the UE receives SIBx, the behavior can refer to scheme 8-6. The UE's reception of SIB1-NB may refer to scheme 8-11.

[0358] In practical implementation, besides using the conflict handling methods described in schemes 8-6 to 8-12 to enhance UE behavior, other enhancement methods can also be considered. Specifically, in some implementations, at least one of the following schemes 8-13 to 8-15 may be included: Option 8-13: Upon receiving a warning message, interrupt (other) uplink or downlink transmissions or switch to idle state.

[0359] The "received warning information" mentioned here may refer to a paging DCI indicating a warning has occurred or containing a warning message received by the UE, or a paging message indicating a warning has occurred or containing a warning message received by the UE, or a SIBx indicating a warning has occurred or containing a warning message received by the UE. The "(other) downlink or uplink transmissions" mentioned here may refer to ongoing downlink or uplink transmissions, pre-configured downlink or uplink transmissions, downlink or uplink transmissions on pre-configured resources, or other downlink or uplink transmissions overlapping with paging PDCCH / paging messages / SIBx. More specifically, for example, if the UE receives a warning indication (e.g., a warning has occurred) from a paging PDCCH (e.g., scheme 8-4-1) or paging message (e.g., scheme 8-4-3), the UE interrupts the ongoing downlink or uplink transmission or switches to idle mode, and then receives / acquires / detects the SIBx containing the warning information / announcement.

[0360] Option 8-14: In the case of uplink transmission, detect the paging PDCCH or paging message or SIBx during the downlink time before the end of the uplink transmission.

[0361] For example, in IoT-NTN TDD mode, the UE may perform uplink transmissions across multiple cycle modes. The UE may not detect the PDCCH before the uplink transmission is complete (e.g., in a single HARQ process scenario). With warning indication support, to reduce the reception latency of warning messages, the UE may be allowed to detect the paging PDCCH / paging message / SIBx using the downlink time in the cycle mode before completing the uplink transmission.

[0362] Option 8-15: The detection of the paging PDCCH is not affected by the DRX (timer / time window), or the paging PDCCH is always detected, or the PDCCH is always detected at the paging time.

[0363] Based on the above-described solutions provided in the embodiments of this application, when a wireless communication device (such as a UE) transmits data with a wireless communication node (such as the network side) in an NTN using TDD according to the determined transmission resources, it can reduce or avoid uplink and / or downlink resource conflicts.

[0364] Figure 17This is a schematic flowchart of a transmission method according to an embodiment of this application. The transmission method can be executed by a wireless communication node. In other words, the transmission method can be executed by software or hardware installed on the wireless communication node. The transmission method includes the following steps.

[0365] S172: The wireless communication node determines the transmission resources, which include the resources for transmission between the wireless communication node and the wireless communication device.

[0366] S174: Wireless communication nodes transmit according to transmission resources.

[0367] In NTN communication systems using TDD for communication, wireless communication nodes can determine transmission resources. These resources include those for transmission between the wireless communication node and wireless communication devices. Transmission is then performed based on these determined resources. The transmission resources determined by the wireless communication node can be time-domain resources related to uplink transmission and / or time-domain resources related to downlink transmission. When transmitting with the wireless communication node based on these determined resources, resource conflicts can be reduced or avoided, such as reducing or avoiding overlap between uplink and non-uplink time intervals and / or overlap between downlink and non-downlink time intervals.

[0368] In some implementations, the transmission resources determined by the wireless communication node may specifically include at least one of the following: Protection interval; The time domain resources of the first transmission include transmissions that overlap with non-transmission times, and the transmissions that overlap with non-transmission times include uplink transmissions that overlap with non-uplink times and / or downlink transmissions that overlap with non-downlink times. The second transmission has time-domain resources and occurs after the first downlink transmission; Time window; Timer; Paging resources; Random access timing; Resources for transmitting warning messages.

[0369] For details on how wireless communication nodes determine the aforementioned transmission resources, please refer to [link / reference needed]. Figure 3 The corresponding content in the illustrated embodiments will not be described again here.

[0370] Based on the technical solutions provided in the embodiments of this application, when a wireless communication node (e.g., the network side) transmits with a wireless communication device (e.g., UE) in NTN using TDD according to the determined transmission resources, it can reduce or avoid uplink and / or downlink resource conflicts.

Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired results.

[0385] In NTN, the path loss is severe due to the large distance between the satellite and the ground UE. Therefore, repeated transmissions may be necessary to improve the detection performance of the user or network side. In traditional terrestrial networks, common PDSCHs may not support repeated transmissions, such as SIBx PDSCH (e.g., PDSCH scheduled by PDCCH scrambled with System Information Radio Network Temporary Identifier SI-RNTI, or PDSCH corresponding to SI-RNTI), Msg2 PDSCH (e.g., PDSCH scheduled by PDCCH scrambled with Random Access Radio Network Temporary Identifier RA-RNTI, or PDSCH corresponding to RA-RNTI), Msg4 PDSCH (e.g., PDSCH scheduled by PDCCH scrambled with Temporary Cell Radio Network Temporary Identifier TC-RNTI, or PDSCH corresponding to TC-RNTI), MsgBPDSCH (e.g., PDSCH scheduled by PDCCH scrambled with MsgB-RNTI, or PDSCH corresponding to MsgB-RNTI), etc. Therefore, to support repeated transmission of the common PDSCH, additional configuration / indication methods are needed to inform the UE whether to use repeated transmission or the number of repeated transmissions. In view of this, embodiments of this application also provide a method and apparatus for determining channel repeated transmissions to solve the problem of how the UE determines whether to use repeated transmissions or the number of repeated transmissions. It is worth noting that the PDCCH scrambled with x-RNTI (e.g., SI-RNTI, RA-RNTI, P-RNTI, MsgB-RNTI, TC-RNTI, etc.) may refer to the DCICRC in the PDCCH being scrambled by x-RNTI, or it may refer to the PDCCH corresponding to x-RNTI.

[0396] 11. A method for determining channel repetitive transmissions, comprising: A wireless communication node sends multiple signaling messages to a wireless communication device. Each signaling message is used to indicate repetitive transmission information of the downlink channel. Different signaling messages indicate different repetitive transmission information. The multiple signaling messages are used by the wireless communication device to determine the repetitive transmission information of the downlink channel.

[0397] Figure 21 This is a flowchart illustrating a method for determining channel repetition transmission according to an embodiment of this application. This method can be executed by a wireless communication device; in other words, it can be executed by software or hardware installed in the wireless communication device. The method for determining channel repetition transmission includes the following steps.

[0398] S212: The wireless communication device receives multiple signaling messages from the wireless communication node. Each signaling message is used to indicate the retransmission information of the downlink channel. Different signaling messages indicate different retransmission information. S214: The wireless communication device determines the retransmission information of the downlink channel based on multiple signaling signals.

[0399] In scenarios where it is necessary to determine the repetition information of the downlink channel, the wireless communication device can receive multiple signaling messages from the wireless communication node. Each signaling message indicates different repetition information for the downlink channel. After receiving multiple signaling messages, the wireless communication device can determine the repetition information of the downlink channel based on these signals. Thus, when transmitting the downlink channel, the wireless communication device can transmit according to the determined repetition information.

[0400] In some implementations, the retransmission information of the downlink channel may include at least one of the following:

[0401] Whether to repeatedly transmit the downlink channel (whether to transmit the downlink channel); The number of repeated transmissions in the downlink channel.

[0402] In some implementations, the downlink channel may include a common PDSCH. This common PDSCH may include at least one of the following: SIBx PDSCH; Msg2 PDSCH; Msg4 PDSCH; MsgB PDSCH; PDSCH without a dedicated PDSCH configuration.

[0403] In some implementations, when a UE reports downlink channel retransmission capability or a downlink channel retransmission request, the number of downlink channel retransmissions is determined based on the downlink channel retransmission information. When a UE does not report downlink channel retransmission capability, does not report a downlink channel retransmission request, or reports a lack of downlink channel retransmission capability, downlink channel retransmission is not performed, or the number of downlink channel retransmissions is not determined based on the downlink channel retransmission information. The downlink channel may include at least one of the aforementioned common PDSCHs. The downlink channel retransmission capability may include at least one of the following: Msg2 PDSCH retransmission capability, Msg4 PDSCH retransmission capability, MsgB PDSCH retransmission capability, and PDSCH retransmission capability when there is no dedicated PDSCH configuration. Whether each downlink channel is retransmitted may be determined based on the corresponding capability report.

[0404] In some embodiments, when the downlink channel is repetitively transmitted, the last repetition transmission of the repetitive transmission or the last time resource may be used as the reference time to determine the transmission time of the HARQ-ACK feedback corresponding to the downlink channel. For example, in the current standard protocol, the HARQ-ACK corresponding to the PDSCH may be reported in the following manner:

[0405] Among them, the end time of the PDSCH repetitive transmission (i.e., time slot n D ), is used as the reference time to determine the time resource or start time of the uplink transmission of the HARQ-ACK (i.e., time slot n + k). Specifically, for the uplink time slot n + k of the HARQ-ACK transmission, where n is the uplink time slot overlapping with time slot n D or the last uplink time slot overlapping with time slot n D

[0406] However, when the downlink channel is repetitively transmitted, the UE may only receive partial transmissions (for example, when the UE does not have the ability to receive repetitive transmissions, it may only receive the first repetitive transmission), or the UE may be able to complete demodulation when only receiving partial repetitive transmissions (for example, when the downlink channel is repetitively transmitted N times, and the UE can demodulate the content of the downlink channel when receiving M < N repetitive transmissions). At this time, if the UE needs to feedback HARQ-ACK (such as Msg4 PDSCH, MsgB PDSCH, or UE-specific PDSCH), early feedback can be considered to shorten the feedback delay. Therefore, the first repetitive transmission of the downlink channel repetitive transmission or any repetitive transmission before the last repetitive transmission can be considered as the reference time to determine the uplink transmission time resource of the HARQ-ACK, so as to terminate the downlink transmission or feedback HARQ-ACK in advance. The network side can detect the HARQ-ACK at the uplink time when HARQ-ACK may be fed back. Once the HARQ-ACK is detected, the network side can consider terminating the downlink transmission or scheduling the next downlink transmission in advance.

[0407] When determining the time resource of the uplink transmission of the HARQ-ACK, at least one of the following times may be used as the reference time (such as time slot n described in the standard D time slot n U ​Or time slot n): the start time of downlink channel repetition transmission, the first repetition of downlink channel repetition transmission, the last time slot of the first repetition of downlink channel repetition transmission, the first time slot of downlink channel repetition transmission, the Mth repetition of downlink channel repetition transmission (e.g., 1≤M≤N), the Mth time slot of downlink channel repetition transmission (e.g., 1≤M≤N), the uplink time slot or the last uplink time slot overlapping with the start time of downlink channel repetition transmission, the uplink time slot or the last uplink time slot overlapping with the first repetition of downlink channel repetition transmission, the uplink time slot or the last uplink time slot overlapping with the last time slot of the first repetition of downlink channel repetition transmission, the uplink time slot or the last uplink time slot overlapping with the first time slot of downlink channel repetition transmission, the uplink time slot or the last uplink time slot overlapping with the Mth repetition of downlink channel repetition transmission (e.g., 1≤M≤N), the uplink time slot or the last uplink time slot overlapping with the Mth time slot of downlink channel repetition transmission (e.g., 1≤M≤N). The above reference time determination method may only be applied to the public PDSCH, or the PDSCH when the UE does not have a dedicated PDSCH configuration. Alternatively, the above reference time determination method may only be applied when the UE reports the capability or request for downlink channel retransmission (e.g., Msg4PDSCH retransmission capability or request). Or, the above reference time determination method may only be applied when the UE does not report the capability or request for downlink channel retransmission (e.g., Msg4 PDSCH retransmission capability or request). After obtaining the reference time, the uplink time of HARQ-ACK can be determined based on the offset k configured on the network side.

[0408] The standard or network side supports using multiple indication methods to indicate repetitive transmission information on the downlink channel. In this case, the network side can indicate these multiple indication methods through multiple signaling, with one signaling corresponding to one indication method. In some implementations, the multiple indication methods may include at least one of the following: MIB / PBCH / SIBx / Common PDSCH indicates whether it is a duplicate; MIB / PBCH / SIBx / common PDSCH indicates one or more repetitions; Following the number of repetitions of SIB1, for example, if the network side indicates the number of repetitions of SIB1 through MIB / PBCH, then subsequent common PDSCH such as Msg4 will use the same number of repetitions as SIB1. The DCI for scheduling the common PDSCH indicates whether it is duplicated; The DCI for scheduling the common PDSCH indicates a repetition count; MIB / PBCH / SIBx / common PDSCH indicates one or more repetitions, and the DCI corresponding to the common PDSCH indicates one of the values ​​or options.

[0409] When the system supports multiple indication methods, it may be necessary to introduce additional indications or define UE behavior to determine which method to apply. Alternatively, when multiple methods are applied simultaneously, it may be necessary to define additional UE behavior to determine which method's indication should be used for repeated transmission. In the embodiments of this application, the wireless communication device determines the repeated transmission information of the downlink channel based on multiple signaling, which may include at least one of the following schemes 0-1 and 0-2: Scheme 0-1: Determine the first signaling from multiple signalings based on the indication information (indication signaling) of the wireless communication node, and determine the repetitive transmission information indicated by the first signaling as the repetitive transmission information of the downlink channel.

[0410] In some implementations, the indication information includes multiple enable messages (enabling signaling) corresponding to multiple signaling messages. One signaling message can correspond to one enabling message, and each enabling message is used to indicate whether the corresponding signaling message is enabled. In this case, the wireless communication device determines the first signaling message from the multiple signaling messages based on the indication information of the wireless communication node, including: The signaling that is enabled by multiple enable messages is designated as the first signaling.

[0411] For example, if there are multiple signaling messages including signaling 1 and signaling 2, and the enable information corresponding to signaling 1 indicates that signaling 1 is not enabled, while the enable information corresponding to signaling 2 indicates that signaling 2 is enabled, then signaling 2 can be determined as the first signaling message, that is, the retransmission information indicated by signaling 2 is determined as the retransmission information for downlink transmission.

[0412] In some implementations, the indication information includes selection information (selection signaling) used to indicate which signaling to select from a plurality of signaling. In this case, the wireless communication device determines a first signaling from the plurality of signaling based on the indication information of the wireless communication node, including: The selected signaling is designated as the first signaling.

[0413] For example, if multiple signaling messages include signaling 1 and signaling 2, and selection information is used to indicate the selection of signaling 1, then signaling 1 can be determined as the first signaling message, that is, the retransmission information indicated by signaling 1 can be determined as the retransmission information for downlink transmission.

[0414] Optionally, in some implementations, the wireless communication device may determine the repetition information of the downlink channel as either the default repetition information or the repetition information of the first channel if it does not receive indication information from the wireless communication node. The default repetition information may be configured by the network side or predefined by the standard. The downlink channel may, for example, include Msg4 PDSCH, and the first channel may, for example, be SIB1 PDSCH.

[0415] To facilitate understanding of scheme 0-1, the following explanation will use the common PDSCH as an example for the downstream channel.

[0416] The standard supports multiple methods for indicating the repetition count of common PDSCHs (such as SIBx PDSCH, Msg4 PDSCH, etc.), for example, indicating the Msg4 PDSCH repetition count via SIB1 and indicating the Msg4 PDSCH repetition count via the DCI that schedules the Msg4 PDSCH. SIB1 / MIB / PBCH indicates which repetition count indication method is used. In this case, when determining the repetition transmission information, the UE can include at least one of the following: N enable signaling instructions are introduced, indicating whether the first indication method, the second indication method, and so on up to the Nth method are enabled. For example, two enable signaling instructions are introduced: one enables the SIB1 method to indicate the number of times Msg4 PDSCH repeats, and the other enables the DCI method to indicate the number of times Msg4 PDSCH repeats.

[0417] A selection signaling is introduced to indicate which of N indication methods to use. For example, a selection signaling is introduced to indicate whether to use SIB1 to indicate the number of times Msg4 PDSCH repeats or DCI to indicate the number of times Msg4 PDSCH repeats.

[0418] When no enable signaling or select signaling is specified, Msg4 PDSCH does not use repeated transmission by default, or the number of repetitions of Msg4 PDSCH is the same as that of SIB1 by default.

[0419] Scheme 0-2: Based on the priority of multiple signaling instructions indicated by the wireless communication node or the priority of multiple signaling instructions defined by the standard, determine the second signaling instruction from the multiple signaling instructions, and determine the repetitive transmission information indicated by the second signaling instruction as the repetitive transmission information of the downlink channel.

[0420] Taking a plurality of signaling messages, including at least one of a third signaling message and a fourth signaling message, where the fourth signaling message has a higher priority than the third signaling message, as an example, the second signaling message is determined from the plurality of signaling messages based on the priority of the plurality of signaling messages indicated by the wireless communication node or the priority of the plurality of signaling messages defined by the standard, including at least one of the following: In the case of multiple signaling messages including a third signaling message, if the third signaling message is received, the third signaling message is identified as the second signaling message; alternatively, if the third signaling message is not received, the retransmission information of the downlink channel is identified as the default retransmission information (which may be configured by the network side or predefined by the standard) or the retransmission information of the first channel. For example, if the downlink channel is Msg4 PDSCH and the first channel is SIB1 PDSCH, the number of retransmissions of SIB1 PDSCH can be used as the number of retransmissions of Msg4 PDSCH. In the case of multiple signaling messages including a fourth signaling message, if the fourth signaling message is received, it is identified as the second signaling message; alternatively, if the fourth signaling message is not received, the retransmission information of the downlink channel is identified as the default retransmission information (which may be configured by the network side or predefined by the standard) or the retransmission information of the first channel. For example, if the downlink channel is Msg4 PDSCH and the first channel is SIB1 PDSCH, the number of retransmissions of SIB1 PDSCH can be used as the number of retransmissions of Msg4 PDSCH. In the case of multiple signaling messages, including third and fourth signaling messages, if the fourth signaling message is received (regardless of whether the third signaling message is received), the fourth signaling message is identified as the second signaling message; if the fourth signaling message is not received (but the third signaling message has been received), the third signaling message is identified as the second signaling message. Optionally, if neither the third nor the fourth signaling message is received, the retransmission information of the downlink channel is identified as the default retransmission information (which may be configured by the network side or predefined by the standard) or the retransmission information of the first channel. For example, if the downlink channel is Msg4 PDSCH and the first channel is SIB1 PDSCH, the number of retransmissions of SIB1 PDSCH can be used as the number of retransmissions of Msg4 PDSCH.

[0421] The third signaling mentioned above can be SIB, and the fourth signaling can be DCI for scheduling the downlink channel.

[0422] It should be noted that Schemes 0-1 and 0-2 can also be used in combination. For example, when there are multiple signaling messages, including the third and fourth signaling messages, and the fourth signaling message has a higher priority than the third signaling message, if the fourth signaling message is received and its enabling signaling message indicates that the fourth signaling message is enabled, the retransmission information indicated by the fourth signaling message is determined as the retransmission information of the downlink channel. If the enabling signaling message of the fourth signaling message indicates that the fourth signaling message is not enabled, then the retransmission information indicated by the third signaling message is determined as the retransmission information of the downlink channel.

[0423] To facilitate understanding of scheme 0-2, the following explanation will use the common PDSCH as an example for the downstream channel.

[0424] The standard supports multiple common PDSCH repetition count indication methods (such as SIBx PDSCH, Msg4 PDSCH, etc.), and these methods can be used simultaneously. The UE determines which indication to use based on the priority defined by the standard or configured on the network side. For example, the DCI indication can override the SIB indication. Alternatively, when both DCI and SIB are indicated, the UE uses the DCI indication. Or, when DCI is indicated, the UE uses the DCI indication and ignores the SIB indication.

[0425] In some more specific implementations, the following schemes may be included: Scheme 0-2-1: The UE can receive the Msg4 PDSCH repetition count indication from the SIB, or it can receive the Msg4 PDSCH repetition count indication from the DCI that schedules the Msg4 PDSCH.

[0426] When the UE receives the Msg4 PDSCH repetition count indication from both the SIB and the scheduling DCI, the UE applies the repetition count indicated in the scheduling DCI.

[0427] Alternatively, the number of Msg4 PDSCH repetitions indicated in the scheduling DCI can override the number of Msg4 PDSCH repetitions indicated in the SIB.

[0428] Alternatively, when the DCI indicates the number of Msg4 PDSCH repetitions, the UE uses the DCI indication and ignores the Msg4 PDSCH repetitions indicated by the SIB.

[0429] Scheme 0-2-2: The UE can determine the number of repetitions of Msg4 PDSCH based on the number of repetitions of SIB1 PDSCH (or the number of repetitions of Msg4 PDSCH is equal to the number of repetitions of SIB1 PDSCH), or it can receive the Msg4 PDSCH repetition count indication from the SIB.

[0430] When the UE receives the Msg4 PDSCH repetition count indication from the SIB, the UE applies the repetition count indicated in the SIB.

[0431] When the UE does not receive the Msg4 PDSCH repetition count indication from the SIB, the Msg4 PDSCH repetition count is equal to the SIB1 PDSCH repetition count. For the method of determining the repetition count of Msg4 PDSCH based on the repetition count of SIB1 PDSCH, there may be an enabling signaling. That is, the UE will only determine the repetition count of Msg4 PDSCH based on the repetition count of SIB1 PDSCH when the enabling signaling is received, or when the enabling signaling enables the method of determining the repetition count of Msg4 PDSCH based on the repetition count of SIB1 PDSCH. In this case, when the UE receives the enabling signaling but does not receive the Msg4 PDSCH repetition count indication from the SIB, the repetition count of Msg4 PDSCH is equal to the repetition count of SIB1 PDSCH. When the UE does not receive the enabling signaling and does not receive the Msg4 PDSCH repetition count indication from the SIB, Msg4 PDSCH is not retransmitted.

[0432] Option 0-2-3: The UE can determine the number of repetitions of Msg4 PDSCH based on the number of repetitions of SIB1 PDSCH (or the number of repetitions of Msg4 PDSCH equals the number of repetitions of SIB1 PDSCH), or it can receive the Msg4 PDSCH repetition count indication from the DCI that schedules Msg4 PDSCH. The UE behavior is consistent with Example 7-2-2, only the "indication in SIB" needs to be changed to "indication in the DCI that schedules Msg4 PDSCH".

[0433] Scheme 0-2-4: The UE can determine the repetition count of Msg4 PDSCH based on the repetition count of SIB1 PDSCH (or the repetition count of Msg4 PDSCH equals the repetition count of SIB1 PDSCH), or it can receive the Msg4 PDSCH repetition count indication from the SIB, or it can receive the Msg4 PDSCH repetition count indication from the DCI that schedules Msg4 PDSCH. The UE behavior is a combination of schemes 0-2-1 to 0-2-3. For example: When the UE receives the Msg4 PDSCH repetition count indication from the DCI of the scheduling Msg4 PDSCH (regardless of whether the Msg4 PDSCH repetition count is indicated in the SIB), the UE applies the repetition count indicated in the scheduling DCI.

[0434] When the UE receives the Msg4 PDSCH repetition count indication from the SIB, but does not receive the Msg4 PDSCH repetition count indication from the DCI that schedules the Msg4 PDSCH, the UE applies the repetition count indicated in the SIB.

[0435] When the UE does not receive a Msg4 PDSCH repetition count indication from the SIB, nor from the DCI that schedules Msg4 PDSCH, the repetition count of Msg4 PDSCH is equal to the repetition count of SIB1 PDSCH.

[0436] The above-mentioned failure to receive the Msg4 PDSCH repetition count indication from the SIB includes both the SIB not indicating it and the method of indicating it via the SIB not being enabled. The above-mentioned failure to receive the Msg4 PDSCH repetition count indication from the DCI that schedules Msg4 PDSCH includes both the DCI that schedules Msg4 PDSCH not indicating it, and the method of indicating it via the DCI that schedules Msg4 PDSCH not being enabled, or not using the DCI that schedules Msg4 PDSCH to indicate the repetition count.

[0437] The above schemes 0-2-1 to 0-2-4 are also applicable to the repeated transmission information as "whether to repeat transmission / perform repeated transmission". You only need to change "repeated number" to "whether to repeat / perform repeated transmission".

[0438] Based on the technical solution provided in the embodiments of this application, when transmitting downlink channels, wireless communication devices can determine the repetitive transmission information of downlink transmission based on multiple received signaling, and transmit downlink channels according to the determined repetitive transmission information.

[0439] Figure 22 This is a flowchart illustrating a method for determining channel repetition transmission according to an embodiment of this application. This method can be executed by a wireless communication node; in other words, it can be executed by software or hardware installed on the wireless communication node. The method for determining channel repetition transmission includes the following steps.

[0440] S222: The wireless communication node sends multiple signaling messages to the wireless communication device. Each signaling message is used to indicate the repetitive transmission information of the downlink channel. Different signaling messages indicate different repetitive transmission information. Multiple signaling messages are used by the wireless communication device to determine the repetitive transmission information of the downlink channel.

[0441] In scenarios where it is necessary to determine the repetition information of the downlink channel, the wireless communication node can send multiple signaling messages to the wireless communication device. Each signaling message indicates different repetition information for the downlink channel. After receiving multiple signaling messages, the wireless communication device can determine the repetition information of the downlink channel based on these signals. In this way, when transmitting the downlink channel, the wireless communication device can transmit according to the determined repetition information.

[0442] In some implementations, the retransmission information of the downlink channel may include at least one of the following:
