Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a resource determination, information transmission method, apparatus, device, and readable storage medium. Background Technology

[0002] Currently, when a terminal performs a bandwidth part (BWP) handover based on Radio Resource Control (RRC) reconfiguration, the success or failure of the BWP handover results in the active BWP on the terminal being either the source BWP or the target BWP. However, in this situation, the base station is unaware of the terminal's BWP handover result and cannot determine whether the active BWP is the source or target BWP, which will affect the base station's resource scheduling. Summary of the Invention

[0003] The purpose of this application is to provide a resource determination, information transmission method, apparatus, device, and readable storage medium to solve the problem that existing base stations cannot determine the activation BWP of a terminal.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] Firstly, a resource determination method is provided, applied to a base station, including:

[0006] Preamble detection is performed on the timing of RACH in the random access channel;

[0007] When the first RACH timing is detected, the bandwidth portion (BWP) to which the first RACH timing belongs is determined, wherein the preamble transmitted on the first RACH timing is the first preamble, and the index of the first preamble is the target preamble index.

[0008] The BWP to which the first RACH timing belongs is determined as the active BWP of the terminal.

[0009] Secondly, an information transmission method is provided, applied to a terminal, including:

[0015] The second determining module is used to determine the BWP to which the first RACH timing belongs as the active BWP of the terminal.

[0016] Fourthly, an information transmission device is provided for use in a terminal, comprising:

[0017] The transmission module is used to transmit the first preamble at the first RACH timing;

[0018] Wherein, the index of the first preamble is the target preamble index, and the BWP to which the first RACH timing belongs is the active BWP of the terminal.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The resource determination method, apparatus, communication device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0030] Please see Figure 1 , Figure 1 This is a flowchart of a resource determination method provided in an embodiment of this application. This method is applied to a base station, such as... Figure 1 As shown, the method includes the following steps:

[0031] Step 11: Perform preamble detection on the RACH timing.

[0032] In this embodiment, the preamble detection described above can be performed on preambles used for non-contention-based random access. For example, preamble detection can be performed on all random access channel (RACH) occasions within the random access (RA) time window.

[0033] Optionally, a preamble for non-contention-based random access can be reserved during RACH resource configuration, and multiple RACH opportunities can be reserved.

[0034] Step 12: When the first RACH timing is detected, determine the BWP to which the first RACH timing belongs.

[0035] In this embodiment, the preamble transmitted during the first RACH is a first preamble, and the index of the first preamble is a target preamble index. The target preamble index can be an index of a preamble reserved for non-contention-based random access as indicated by the base station, used by the terminal to trigger non-contention-based random access.

[0036] Step 13: Determine the BWP to which the first RACH timing belongs as the active BWP of the terminal.

[0037] Here, the association between RACH timing and BWP can be determined based on predefined criteria, protocol agreements, and / or network configuration. When the first RACH timing is detected, the BWP to which the first RACH timing belongs can be determined based on the association between the RACH timing and the BWP, and the BWP to which the first RACH timing belongs can be identified as the active BWP of the terminal.

[0038] The resource determination method in this application embodiment detects the preamble of the RACH timing. When a first RACH timing is detected, the BWP to which the first RACH timing belongs is determined. The preamble transmitted on the first RACH timing is the first preamble, and the index of the first preamble is the target preamble index. The BWP to which the first RACH timing belongs is determined as the active BWP of the terminal. By leveraging the association between RACH timing and BWP, the base station can determine the active BWP of the terminal based on the detected specific RACH timing (i.e., the first RACH timing).

[0039] Optionally, the above-mentioned BWP activation is related to the RRC reconfiguration process. Before performing preamble detection for the RACH timing, the resource determination method in this embodiment may further include:

[0040] The base station sends a control command in a first time unit and an RRC reconfiguration message in a second time unit; wherein, the control command carries a target preamble index; the activated BWP is the source BWP or target BWP when performing BWP handover based on the RRC reconfiguration message; the first time unit is located before the second time unit.

[0041] In some embodiments, the control command is a Physical downlink control channel (PDCCH) command, i.e., a PDCCH order. For example, the Random Access Preamble index field in the PDCCH order is filled with a preamble index reserved for non-contention-based random access as the target preamble index, triggering non-contention-based random access.

[0042] In some embodiments, the first time unit and the second time unit can be two consecutive time units. The first time unit and the second time unit are adjacent time units.

[0043] In some embodiments, the first time unit and the second time unit can be selected as slots, subframes, or symbols. For example, the first time unit is downlink slot N, the second time unit is downlink slot N+1, a PDCCH order is sent in slot N, and an RRC reconfiguration message is sent in slot N+1.

[0044] In some embodiments, when performing BWP handover based on RRC reconfiguration, if the detected first RACH timing belongs to the source BWP, the terminal's currently active BWP can be determined as the source BWP; if the detected first RACH timing belongs to the target BWP, the terminal's currently active BWP can be determined as the target BWP. Subsequently, based on this determined active BWP, downlink control information (DCI) and uplink / downlink resource scheduling can be performed in the UE-specific search space (USS), such as retransmission scheduling when a UL grant in RAR requires retransmission.

[0045] This mechanism allows for the sequential coordination of control commands (such as PDCCH order) and RRC reconfiguration messages. It enables the random access procedure (e.g., non-contention-based random access procedure) and the RRC reconfiguration procedure to be triggered sequentially. If the random access procedure is interrupted by the RRC reconfiguration procedure, a preamble is sent when the random access procedure automatically resumes after the RRC reconfiguration is completed. This allows the terminal to proactively inform the base station of the RRC reconfiguration result (e.g., BWP handover result) through the random access procedure. This avoids the ambiguity that might occur before the base station receives the RRC reconfiguration complete message from the terminal, reducing the waiting time for the RRC reconfiguration complete message. Furthermore, it enhances the accuracy of the base station's prediction of terminal BWP activation, allowing for more accurate scheduling during BWP activation and improving the reconfiguration success rate.

[0046] Optionally, the RACH occasions before and after RRC reconfiguration need to be configured differently. For example, when performing BWP handover based on RRC reconfiguration, the RACH occasions of the source BWP and the target BWP are configured differently. The aforementioned RRC reconfiguration message may include first configuration information, which is used to configure different RACH occasions for the source BWP and the target BWP when performing BWP handover. This allows the terminal to actively inform the base station of the BWP handover result through the random access procedure, thereby enabling the base station to determine the active BWP of the terminal based on the detected specific RACH occasion.

[0047] Optionally, the base station can send second configuration information to the terminal. This second configuration information is used to configure different RACH timings for the source BWP and the target BWP during BWP handover. This allows the terminal to actively inform the base station of the BWP handover result through the random access procedure, thereby enabling the base station to determine the terminal's active BWP based on the detected specific RACH timing.

[0048] Optionally, if no first RACH opportunity is detected within the random access window (RA window), and the waiting time is greater than or equal to a preset threshold, the base station may transmit a first DCI on the source BWP and a second DCI on the target BWP. The first DCI includes a first Resource Indicator Value (RIV) obtained from the source BWP, and the second DCI includes a second RIV obtained from the target BWP. The first RIV and the second RIV indicate the same uplink licensed resource location (e.g., PUSCH resource location). Since the Resource Indicator Value (RIV) needs to be calculated based on the corresponding BWP size, the first RIV obtained from the source BWP can be understood as the first RIV calculated based on the size of the source BWP, and the second RIV obtained from the target BWP can be understood as the second RIV calculated based on the size of the target BWP, with both indicating the same uplink licensed resource location.

[0049] In this way, by generating two uplink scheduling DCIs, the terminal can detect one of them based on its activated BWP, and by indicating the same uplink authorized resource location, the uplink authorized resource location can be uniquely identified, avoiding the possibility of two uplink authorized resource locations due to inconsistent interpretation of the activated BWP.

[0050] In some embodiments, the preset threshold can be set based on actual needs. For example, the preset threshold is equal to T. RRCproceduredelay With T BWPswitchDelayRRC The sum of. Where, T RRCproceduredelay T represents the execution time required by the terminal to perform the RRC signaling process, in milliseconds (ms). The specific value can be defined according to the RRC message type; for example, for an RRC reconfiguration message during BWP handover, T... RRCproceduredelay Equals 10ms. T BWPswitchDelayRRC The execution time required for a terminal to perform a BWP handover is, for example, 6ms. Therefore, the maximum time for RRC reconfiguration BWP handover is 16ms. It should be noted that the above time is a very lenient requirement for the terminal; the actual execution time is usually shorter. However, the base station cannot accurately know the actual time it takes for the terminal to complete the execution and restore signal transmission and reception, and waiting until the maximum time is reached before granting the terminal a UL grant is not timely.

[0051] Optionally, after determining the activation BWP of the terminal, the base station can perform resource scheduling according to the activated BWP. For example, uplink resource scheduling can be performed through the uplink grant in the Random Access Response (RAR), where the modulation and coding scheme (MCS) can adopt the corresponding level of Quadrature Phase Shift Keying (QPSK) to improve reliability. The Physical Uplink Shared Channel (PUSCH) is then received at the corresponding UL grant location.

[0052] In this way, resource scheduling can be carried out based on the consistent understanding between the base station and the terminal when activating the BWP. Therefore, when scheduling resources on the activated BWP USS, resources of any location and size can be scheduled, avoiding the limitation on the scheduling of some resource locations and sizes caused by insufficient size of the DCI resource field on the CSS when the activated BWP is larger than the initial BWP.

[0053] In some embodiments, after detecting the first RACH opportunity, the base station can send a Random Access Response (RAR). The RAR includes the uplink grant obtained according to the activated BWP, meaning the uplink resources scheduled by the RAR UL grant are within the activated BWP. This enables a natural coordination process between RRC reconfiguration and control commands (such as PDCCH orders) triggering random access, because uplink scheduling after PDCCH order triggers random access will use the RAR UL grant instead of DCI. Specifically, when the activated BWP includes the initial BWP, the uplink resources scheduled by the RAR UL grant are always within the initial BWP.

[0054] Optionally, when the activated BWP includes the initial BWP, resource scheduling can be performed according to the initial BWP regardless of whether the activated BWP is the initial BWP. For example, RAR UL grants are all understood as initial BWPs, and the uplink resources scheduled by RAR UL grants are always within the initial BWP. In this way, regardless of the size and starting position of the activated BWP, as long as the initial BWP is within the range of the activated BWP, the PUSCH that has completed bearer reconfiguration can always be scheduled within the range of the initial BWP, ensuring that the resource position is unique and improving the reconfiguration success rate.

[0055] Please see Figure 2 , Figure 2 This is a flowchart of an information transmission method provided in an embodiment of this application. The method is applied to a terminal, such as... Figure 2 As shown, the method includes the following steps:

[0056] Step 21: Transmit the first preamble at the first RACH timing.

[0057] In this embodiment, the index of the first preamble is the target preamble index, and the BWP to which the first RACH timing belongs is the terminal's active BWP. The target preamble index can be the index of a preamble reserved for non-contention-based random access as indicated by the base station, used by the terminal to trigger non-contention-based random access.

[0058] Optionally, a preamble for non-contention-based random access can be reserved during RACH resource configuration, and multiple RACH opportunities can be reserved.

[0059] Optionally, the relationship between RACH timing and BWP can be determined based on predefined, protocol agreements, and / or network configurations.

[0060] The information transmission method of this application embodiment transmits a first preamble at a first RACH timing. By leveraging the correlation between the RACH timing and the BWP, the base station can determine the active BWP of the terminal based on the detected specific RACH timing (i.e., the first RACH timing).

[0061] Optionally, the above-mentioned BWP activation is related to the RRC reconfiguration process. Before transmitting the first preamble at the first RACH timing, the information transmission method in this embodiment may further include:

[0062] The terminal receives a control command in a first time unit and an RRC reconfiguration message in a second time unit; wherein the control command carries a target preamble index; the activated BWP is the source BWP or target BWP when performing BWP handover based on the RRC reconfiguration message; the first time unit is located before the second time unit.

[0063] In some embodiments, the control command is a PDCCH order. For example, the Random Access Preamble index field in the PDCCH order is filled with a preamble index reserved for non-contention-based random access as the target preamble index, triggering non-contention-based random access.

[0064] In some embodiments, the main operation flow of the terminal is as follows: 1) After receiving the PDCCH order, a non-contention random access procedure is triggered; 2) After receiving the RRC reconfiguration message, the RRC reconfiguration is performed; 3) After the RRC reconfiguration is completed, the state of not being able to send or receive messages ends, the Medium Access Control (MAC) entity in the terminal initializes the random access procedure, and sends the specified non-contention preamble, the corresponding index of which is the preamble index carried in the PDCCH order; 4) After receiving the RAR (such as msg2), the PUSCH is sent according to the RAR UL grant; if the RAR (such as msg2) is not received, the non-contention preamble continues to be sent according to the configuration; 5) When the DCI on the USS is received (only the DCI understood according to the BWP activated by itself can be received), the PUSCH is sent.

[0065] In some embodiments, the first time unit and the second time unit can be two consecutive time units.

[0066] In some embodiments, the first time unit and the second time unit may be selected as slots, subframes, or symbols. For example, the first time unit is downlink slot N, and the second time unit is downlink slot N+1. A PDCCH order is received in slot N, and an RRC reconfiguration message is received in slot N+1.

[0067] In this way, by using control commands in conjunction with RRC reconfiguration messages, the random access procedure (such as a non-contention random access procedure) and the RRC reconfiguration procedure can be triggered sequentially. This allows the terminal to proactively inform the base station of the RRC reconfiguration result (such as the BWP handover result) through the random access procedure, avoiding the ambiguity that may occur when the base station is unclear about the terminal's RRC reconfiguration result before receiving the RRC Reconfiguration Complete message from the terminal.

[0068] Optionally, the aforementioned RRC reconfiguration message may include first configuration information, which is used to configure different RACH timings for the source BWP and the target BWP during BWP handover. This allows the terminal to actively inform the base station of the BWP handover result through a random access procedure, thereby enabling the base station to determine the terminal's active BWP based on the detected specific RACH timing.

[0069] Optionally, the terminal can receive second configuration information from the base station. This second configuration information is used to configure different RACH timings for the source BWP and the target BWP during BWP handover. This allows the terminal to proactively inform the base station of the BWP handover result through a random access procedure, thereby enabling the base station to determine the terminal's active BWP based on the detected specific RACH timing.

[0070] In some embodiments, after transmitting the first preamble at the first RACH timing, the terminal can receive a random access response, which includes uplink grants obtained according to the activated BWP, i.e., the uplink resources scheduled by the RAR UL grant are within the activated BWP, to achieve a natural coordination process of RRC reconfiguration and control commands (such as PDCCH orders) triggering random access. Specifically, when the activated BWP includes the initial BWP, the uplink resources scheduled by the RAR UL grant are necessarily within the initial BWP.

[0071] It should be noted that the resource determination method provided in this application embodiment can be executed by a resource determination device or a control module within that resource determination device for executing the resource determination method. This application embodiment uses the execution of the resource determination method by a resource determination device as an example to illustrate the resource determination device provided in this application embodiment.
