[0049] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0050] The term "comprising," and any variations thereof, used in this disclosure and in the claims are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of operations or units is not necessarily limited to those explicitly listed, but may include other operations or units not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.
[0051] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0052] Referring to Figure 1, an embodiment of this disclosure provides a transmission method applied to a terminal, the specific operations of which include:
[0053] Operation 11: Receive the first message;
[0054] Operation 12: In response to the first information, perform the first operation;
[0055] The execution of the first operation includes at least one of the following:
[0056] 1) Based on the first information, determine whether to send the first message;
[0057] In some embodiments, the first information may be configuration information or configuration parameters.
[0058] In some embodiments, the first message may be message 3 (Msg3), wherein sending the first message includes contention-based message 3 early data transmission (CB-Msg3 EDT).
[0059] In this embodiment, based on the first information, the terminal can use a contention-based first message early transmission mechanism to transmit data, ensuring the effective use of resources and avoiding conflicts.
[0060] 2) Based on the first information, at least a partial copy of the first message is transmitted in the first window, wherein the first information includes configuration information of one or more first windows;
[0061] In some embodiments, the first information may be window configuration information.
[0062] In some embodiments, a replica may also be referred to as a duplicate transmission. A replica of the first message is multiple transmission versions of the same first message. Each replica is a different instance of the first message transmitted in the network, used to ensure reliable message transmission. Even if some replicas are lost or erroneous, it is still guaranteed that the first message will eventually reach the receiving end successfully.
[0063] In this embodiment, the configuration information of the first window can reduce conflicts between multiple copies of a terminal or multiple copies of multiple terminals.
[0064] 3) Based on the first information, receive a second message corresponding to at least a partial copy of the first message in the second window, wherein the first information includes configuration information for one or more second windows;
[0065] In some embodiments, the second window may also be referred to as the second message receiving window.
[0066] In some embodiments, the second message may be message 4 (Msg4).
[0067] In some embodiments, at least a partial copy of the first message may include all copies of the first message.
[0068] In some embodiments, within the second window, after sending each copy of the first message, the terminal sleeps for a first time and then listens for the second message corresponding to that copy; wherein, the first time is the round-trip time between the terminal and the network node.
[0069] 4) Based on the first information, determine the wireless network temporary identifier RNTI used to descramble the second message.
[0070] In this embodiment, in some embodiments, the first information can be carried by at least one of the following: system information, Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), and Downlink Control Information (DCI).
[0071] In one embodiment of this disclosure, when the first message has no copy or only one copy, the RNTI is determined based on the uplink transmission resources of the first message; or, when the first message has one or more copies, the RNTI is determined based on the window for transmitting copies of the first message, or based on the uplink transmission resources of copies of the first message.
[0072] In this embodiment, the terminal can dynamically determine the RNTI used to descramble the second message, ensuring a reliable descrambling process for the second message even when the first message has no copy or only one copy, through reasonable resource configuration. Based on different copy counts (e.g., one copy or multiple copies), the terminal can adaptively determine the corresponding RNTI using specific resources configured on the network side. This improves the accuracy and reliability of the terminal's decoding of the second message, avoiding problems such as ambiguous terminal behavior or incorrect RNTI determination due to varying copy counts.
[0073] The embodiments disclosed herein improve the success rate of contention-based first message transmission in IoT non-terrestrial networks and reduce resource conflicts through refined resource allocation and transmission strategies, thereby optimizing communication efficiency and network resource utilization.
[0074] In one embodiment of this disclosure, determining whether to send a first message based on the first information includes:
[0075] If the first information includes the second information, and the second information is a reference signal received power (RSRP) threshold configured for different coverage enhancement levels and / or orthogonal cover codes (OCC), it is determined whether to send the first message.
[0076] In this embodiment, the network-side device can configure the corresponding RSRP threshold for the terminal according to different CE levels. If the terminal determines that the current RSRP is higher than the RSRP threshold, it can use a contention-based early data transmission mechanism at that CE level.
[0077] In one embodiment of this disclosure, determining whether to send a first message includes:
[0078] If the measured current RSRP is greater than the RSRP threshold, then a first message is sent at the coverage enhancement level.
[0079] In this embodiment, the network-side device configures an independent RSRP threshold for each (per) OCC for the terminal. The RSRP threshold is configured according to each CE level. If the terminal determines that the current RSRP is higher than the RSRP threshold, it can use the contention-based first message early transmission mechanism at the CE level corresponding to the RSRP threshold.
[0080] In one embodiment of this disclosure, the configuration information of the first window includes start and end time information of the first window, which includes at least one of the following: the start time of the first window and the duration of the first window; the start time of the first window and the end time of the first window; and the relative time interval between the first windows.
[0081] In this embodiment, the relative time interval between the first windows is applicable to the case where the network side configures consecutive first windows. In this case, only the start and end time information of the first first window needs to be configured, and subsequent first windows can be determined based on the relative time interval.
[0082] Referring to Figure 3, the start time of the first window is UTC t1, the end time of the first window is UTC t2, the start time of the second window is the end time of the first window, and the time interval between the end time and the start time of the second window is Δt. The start time of the third window is the end time of the second window, and the time interval between the end time and the start time of the third window is Δt.
[0083] Referring to Figure 4, the start time of the first window is UTC t1, the duration of the first window is duration1, the start time of the second window is UTC t2, the duration of the first window is duration2, the start time of the third window is UTC t3, and the duration of the third window is duration3.
[0084] In one embodiment of this disclosure, the configuration information of the first window further includes at least one of the following: the effective time information of the first window; the number of the first windows; and the association between the first window and the start and end times.
[0085] The validity period information of the first window is used to indicate the validity restriction of the first window.
[0086] In one embodiment of this disclosure, the number of the first windows is determined based on the number of copies and / or the number of terminals.
[0087] In some embodiments, for a single terminal, the number of first windows can be greater than or equal to the number of replicas; for multiple terminals, the number of first windows can be greater than or equal to the number of terminals, or further greater than or equal to the number of terminals × the number of replicas.
[0088] In one embodiment of this disclosure, the association between the first window and the start and end times is provided in one or more of the following ways:
[0089] 1) Start and end time information for each first window;
[0090] In some embodiments, the start and end time information includes start time information and / or end time information.
[0091] 2) Start and end time information of the first window, relative time interval information of subsequent windows relative to the first window, or relative time interval information of subsequent windows relative to the previous window.
[0092] In one embodiment of this disclosure, before or after operation 11 or operation 12, the method further includes:
[0093] A fourth message is received, which indicates that the configuration information of the first window has changed, or that the configuration information of the first window has not changed.
[0094] For example, setting the fourth information to 1 indicates that the configuration information of the first window has changed, and setting the fourth information to 0 indicates that the configuration information of the first window has not changed.
[0095] In some embodiments, the fourth information further includes at least one of the following: updated configuration information of the first window, and information on the amount of change of the updated configuration information of the first window relative to the previous configuration information of the first window.
[0096] In one embodiment of this disclosure, the configuration information of the second window is configured for each terminal.
[0097] In one embodiment of this disclosure, the second window satisfies at least one of the following:
[0098] 1) The start time of the second window is: the time when the terminal successfully sends the data packet for the first time plus the time of round trip between the terminal and the network node; wherein, the network node includes, but is not limited to, at least one of the following: base station, satellite, centralized unit (CU), and distributed unit (DU).
[0099] 2) The duration of the second window is determined based on at least one of the following: network-side packet processing latency, number of replicas, replica transmission interval, number of repetitions, and round-trip time (RTT) between the terminal and the network node.
[0100] The specific calculation example is as follows:
[0101] Start time of the first window: T start =t First successful data packet transmission + RTT UE- 基站 .
[0102] Duration of the first window (T) duration The calculation of the replication interval is divided into two cases: uniform and non-uniform. For the case of 1 repetition, the following calculation examples are given for each of these two cases:
[0103] 1) Uniform replica spacing: T duration =Network-side packet processing latency × (1 + number of replicas) + Number of replicas × Replica transmission interval + Number of replicas × RTT UE-基站 .
[0104] 2) Non-uniform replica spacing: T duration =Network-side packet processing latency × (1 + number of replicas) + Δt1 + Δt2 + ... + Δtn + number of replicas × RTT UE- 基站 , where n is the number of replicas, Δtx is the interval between adjacent replicas, Δt1 is the interval between the first replica and the first transmission, Δt2 is the interval between the second replica and the first replica, and so on.
[0105] To further consider power consumption, for cases where the replica transmission interval exceeds a certain threshold, within the aforementioned large receiving window, the terminal can sleep for RTT after sending the first message and then wake up to listen for the second message. Then, for each replica, it wakes up again after its respective sleep replica transmission interval to listen for the second message corresponding to each replica. This is similar to an alarm clock mechanism, waking up only at the corresponding time to check the network response message and sleeping at other times to save power consumption for response listening.
[0106] As shown in Figure 5, in one embodiment, after the terminal sends the first message (e.g., Msg3), it sends a copy of the first message at an interval of Δt1, and then sends another copy of the first message at an interval of Δt2. The terminal enters sleep mode after sending the first message, and the interval is RTT. UE- 基站 It wakes up and listens to the PDCCH, then goes into sleep mode again. After an interval of Δt1, it wakes up and listens to the PDCCH again, then goes into sleep mode again. After an interval of Δt2, it wakes up and listens to the PDCCH again.
[0107] In one embodiment of this disclosure, the configuration information of the second window is configured for each copy of each terminal.
[0108] At this point, the terminal reopens the second window after each copy transmission. The second window is opened / reopened after each successful transmission of the first message plus the UE-base station RTT. The duration of the second window needs to take into account one or more of the following: network-side packet processing latency, repetition count, and UE-base station RTT time. The duration is at least T. duration =Network-side packet processing latency + RTT UE- 基站 .
[0109] In one embodiment of this disclosure, the second window satisfies at least one of the following:
[0110] 1) The start time of the second window is: the time point when the terminal successfully sends a data packet plus the round-trip time between the terminal and the network node;
[0111] 2) The duration of the second window is determined based on at least one of the following: network-side packet processing latency, number of repetitions, and round-trip time between the terminal and the network node.
[0112] In one embodiment of this disclosure, when the RNTI is determined based on a window of copies of the first message being transmitted, the RNTIs of the second messages corresponding to all copies of the first message used to descramble the first message are the same.
[0113] In one embodiment of this disclosure, when the RNTI is determined based on the uplink transmission resources of a copy of the first message, the RNTI of the second message corresponding to each copy of the first message used to descramble the first message is different.
[0114] In one embodiment of this disclosure, for standalone (SA) networking, i.e. without replicas, the RNTI of the Physical Downlink Control Channel (PDCCH) for scrambling the scheduling of the second message is calculated based on the uplink transmission resources (including time domain, frequency domain, and code domain resources) configured on the network side for the first message.
[0115] In one embodiment of this disclosure, a single RNTI is used to scramble or descramble the second message for all replicas. Specifically, the network side uses the RNTI to scramble the PDCCH of the second message corresponding to all replicas, and the terminal side uses the RNTI to descramble the PDCCH of the second message corresponding to each replica. The RNTI is provided by the network side in the system information, and the calculation of the RNTI needs to consider the window of the replica transmitting the first message.
[0116] In one embodiment of this disclosure, a second message is scrambled / descrambled using an RNTI for each copy of the first message. Each RNTI is calculated based on the uplink transmission resources (such as time domain, frequency domain, and code domain resources) of the corresponding copy of the first message.
[0117] In this disclosure, by receiving first information and according to the configuration parameters therein, the terminal can transmit a copy of the first message within a first window, or receive a second message corresponding to a copy of the first message within a second window. This configuration allows for flexible adjustment of the resource selection window, reducing transmission conflicts and ensuring the effectiveness of resource allocation. Through dynamic window configuration, the terminal can select appropriate time slots for transmission and reception at different times, improving resource utilization efficiency. Furthermore, this disclosure ensures accurate descrambling of the received second message even when the first message has no copy or only one copy, by dynamically configuring the RNTI used to descramble the second message. When the first message has a copy, the RNTI determination is adjusted based on the copy's window or transmission resources, further optimizing the response reception mechanism. This flexible RNTI configuration scheme ensures that the terminal can correctly decode the response message, avoiding packet loss or retransmission due to incorrect RNTI configuration, thus improving communication reliability and success rate.

[0152] In one embodiment of this disclosure, when the RNTI is determined based on the uplink transmission resources of a copy of the first message, the RNTI of the second message corresponding to each copy of the first message used to descramble the first message is different.
[0153] In this disclosure, the network-side device sends first information to the terminal, enabling the terminal to receive the first information and, based on the configuration parameters therein, to transmit a copy of the first message within a first window, or to receive a second message corresponding to a copy of the first message within a second window. This configuration allows for flexible adjustment of the resource selection window, reducing transmission conflicts and ensuring the effectiveness of resource allocation. Through dynamic window configuration, the terminal can select appropriate time slots for transmission and reception at different times, improving resource utilization efficiency. Furthermore, this disclosure ensures accurate descrambling of the received second message even when the first message has no copy or only one copy, by dynamically configuring the RNTI used for descrambling the second message. When the first message has a copy, the RNTI determination is adjusted based on the copy's window or transmission resources, further optimizing the response reception mechanism. This flexible RNTI configuration scheme ensures that the terminal can correctly decode the response message, avoiding packet loss or retransmission due to incorrect RNTI configuration, thus improving communication reliability and success rate.
