Description

Technical Field

[0001] This application belongs to the field of mobile communication technology, and specifically relates to a random access resource configuration method, apparatus, terminal and network-side equipment. Background Technology

[0002] In New Radio (NR) systems, the uplink signal during random access, such as message 1 (Msg1) in a 4-step random access channel (4-step RACH), has poor coverage performance compared to other channels. Therefore, it is necessary to introduce repeated transmission of Msg1 in the Physical Random Access Channel (PRACH) to improve the coverage performance of Msg1.

[0003] The association period for the Synchronization Signal Block (SSB) and the Random Access Response (RO) can be selected as 10ms, 20ms, 40ms, 80ms, and 160ms. The corresponding Random Access Response (RAR) listener window length is a maximum of 10ms. Therefore, the association period may be longer than the RAR listener window length. In this case, if multiple ROs within the association period are still used to implement repeated Msg1 transmissions, the time interval between each Msg1 transmission will be longer than the RAR listener window. If only existing PRACH resources are used for repeated Msg1 transmission, the Msg1 transmission interval is too long, which is equivalent to repeatedly trying to perform multiple Msg1 single transmissions, resulting in increased latency in the terminal access process. The long transmission interval also affects the diversity gain of repeated Msg1 transmission. When transmitting Msg1, the appropriate downlink reference beam is selected based on the Reference Signal Received Power (RSRP) of the SSB. If the time interval is too long, the validity of the downlink parameter beam will expire.

[0004] Existing RO resources do not support repeated transmission of random access signals, and cannot effectively improve the diversity gain brought by repeated transmission. Summary of the Invention

[0024] The random access resource configuration method, apparatus, terminal, and network-side equipment provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0025] like Figure 2 As shown in the figure, this application provides a method for random access resource configuration. The execution subject of this method is a terminal; in other words, this method can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0026] S210, The terminal receives first configuration information from the network-side device, the first configuration information being used to configure a first RO resource set and / or a second RO resource set for repeated transmission of random access signals.

[0027] The first RO resource set includes at least one of the following RO resources: RO resources for 4-step RACH; RO resources accessed via a 2-step random access (RACH) process; RO resources for 4-step RACH for requesting Msg3 repetition.

[0028] It should be understood that the repeated transmission of the random access signal can be the repeated transmission of Msg1 in 4-step RACH, and the first RO resource information and the second RO resource set include RO resources that can be used to perform the repeated transmission of Msg1 in 4-step RACH.

[0029] It should be understood that the RO resources for repeated transmission of random access signals can be multiplexed with at least one of the RO resources of 4-step RACH, RO resources of 2-step RACH, or RO resources for repeated transmission of Msg3. The first RO resource set can be obtained by dividing the preamble resource set corresponding to at least one of the above-mentioned RO resources. For example, if the terminal supports 4-step RACH and is configured with 4-step RACH RO resources, the first RO resource set may include 4-step RACH RO resources. The preamble corresponding to the 4-step RACH RO resources that serve as the first RO resources in the first RO resource set can be used for repeated transmission of random access signals, i.e., for repeated transmission of Msg1. If the terminal supports 2-step RACH and is configured with 2-step RACH RO resources, the first RO resource set may also include 2-step RACH RO resources. The preamble corresponding to the 4-step RACH RO resources that serve as the first RO resources in the first RO resource set can be used for repeated transmission of random access signals, i.e., for repeated transmission of Msg1. The preamble resource corresponding to the RO resource of RACH can be used for repeated transmission of random access signals, i.e., for repeated transmission of Msg1; when the terminal supports repeated transmission of Msg3 and is configured with RO resources for repeated transmission of Msg3, the first RO resource set may also include RO resources for repeated transmission of Msg3. The preamble resource corresponding to the RO resource for repeated transmission of Msg3 in the first RO resource set can be used for repeated transmission of random access signals, i.e., for repeated transmission of Msg1.

[0030] Network-side devices can also configure a first RO resource set for each type of RO resource.

[0031] In one implementation, the network-side device can configure a terminal with a first RO resource set including 4-step RACH RO resources and / or a second RO resource set including dedicated RO resources.

[0032] In another implementation, the network-side device may configure the terminal with a first RO resource set including RO resources of 2-step RACH and / or a second RO resource set including dedicated RO resources.

[0033] In another implementation, the network-side device may configure the terminal with a first set of RO resources including Msg3 repeated transmissions of RO resources and / or a second set of RO resources including dedicated RO resources.

[0034] In another implementation, the network-side device can simultaneously configure the terminal with a first set of RO resources including 4-stepRACH RO resources and Msg3 repeated transmission RO resources and / or a second set of RO resources including dedicated RO resources.

[0035] like Figure 3 Optionally, the network-side device divides the RO resources for Msg1 repeated transmission into a first RO resource set from the set of RO resources for 4-step RACH, RO resources for 2-step RACH, and RO resources for Msg3 repeated transmission, and configures a corresponding number of repetitions N0, N1, and N2 for each first RO resource. N0, N1, and N2 can be the same or different.

[0036] However, for the sake of simplicity, the following embodiments will be illustrated by the example of the network-side device configuring the terminal with a first RO resource set including 4-step RACH RO resources and / or a second RO resource set including dedicated RO resources.

[0037] The second set of RO resources includes dedicated RO resources for repeated transmission of random access signals only.

[0038] It should be understood that the first configuration information sent by the network-side device to the terminal may include a first message and / or a second message based on actual needs, wherein the first message is used to configure a first RO resource set for the terminal, and the second message is used to configure a second RO resource set for the terminal.

[0039] S220, The terminal determines the association relationship of RO resources in the first RO resource set and / or the second RO resource set.

[0040] Furthermore, step S220 includes determining at least one of the following relationships: The relationships between RO resources in the first RO resource set; The relationships between RO resources in the second RO resource set; The association between the RO resources in the first RO resource set and the RO resources in the second RO resource set.

[0041] It should be understood that the determination of the association relationship can be implemented in multiple ways. It can be determined according to predefined mapping criteria (also known as association criteria) or through association identification information. The association relationship can be used to represent RO resources that are associated, or it can represent the association information of RO resources that are associated, such as being used for the same Msg1 repeated transmission, corresponding to the same number of repetitions, or corresponding to the same SSB or SSB set, etc.

[0042] S230, the terminal determines N RO resources based on the association relationship of RO resources in the first RO resource set and / or the second RO resource set to perform N random access signal repetition transmissions, where N is a positive integer.

[0043] The terminal can determine N RO resources that meet the requirements of this random access signal retransmission from the associated first RO resources and / or second RO resources, and perform N random access signal retransmissions.

[0044] The N random access signal repetition transmissions refer to performing random access signal transmissions in N RO resources respectively. For example, Msg1 carrying the preamble corresponding to the Msg1 repetition transmission can be transmitted in N first RO resources (4-step RACH RO resources respectively).

[0045] It should be understood that if the network-side device configures only the first RO resource set for the terminal, then all N random access signal repetitions performed by the terminal will be on the first RO resource; if the network-side device configures only the second RO resource set for the terminal, then all N random access signal repetitions performed by the terminal will be on the second RO resource; if the network-side device configures both the first and second RO resource sets for the terminal, then of the N random access signal repetitions performed by the terminal, N1 may be on the first RO resource and N2 may be on the second RO resource, where N1 + N2 = N, and N1 and N2 are integers greater than or equal to 0.

[0046] As can be seen from the technical solutions of the above embodiments, the random access resource configuration method provided in this application receives first configuration information through a network-side device. The first configuration information is used to configure a first RO resource set and / or a second RO resource set for repeated transmission of random access signals. The first RO resource set may include RO resources for 4-step RACH, RO resources for 2-step RACH, or RO resources for 4-step RACH with Msg3 repeated transmission. The second RO resource set includes dedicated RO resources. Then, the association relationship of RO resources in the first RO resource set and / or the second RO resource set is determined. Then, N RO resources are determined according to the association relationship of RO resources in the first RO resource set and / or the second RO resource set to perform N repeated transmissions of random access signals. This can support repeated transmissions of random access signals with a larger number of repetitions, complete repeated transmissions of random access signals in a shorter time, obtain better diversity gain, and enable the system to efficiently utilize RO resources through different combinations of RO resources.

[0047] Based on the above embodiments, further, an example is given using a network-side device configured with a first RO resource set and a second RO resource set as the terminal. Figure 4 As shown, step S210 includes: S211. The terminal receives a first message from the network-side device, the first message being used to configure a first RO resource set for the terminal for repeated random access signal transmission.

[0048] In one implementation, the first message may be carried in a Radio Resource Control (RRC) message, such as System Information Block (SIB) 1 or the Random Receive Channel Configuration Message RACHconfigcommon.

[0049] In one implementation, the first message includes at least one of the following: A first preamble resource set corresponding to the first RO resource in the first RO resource set, wherein the first preamble resource set includes a first preamble resource for repeated transmission of random access signals; The number of repetitions M1 corresponding to the first RO resource; The first identifier information corresponding to the first RO resource.

[0050] It should be understood that the first RO resource in the first RO resource set can be at least one of 4-step RACH RO resources, 2-step RACH RO resources, or 4-step RACH RO resources with Msg3 repeated transmission. The first RO resource set can be some or all of the RO resources mentioned above, that is, the first RO resource set may include all or some of the 4-step RACH RO resources, all or some of the 2-step RACH RO resources, or at least one of the 4-step RACH RO resources with Msg3 repeated transmission.

[0051] It should be understood that the first preamble resource set configured for the first RO resource includes the preamble resources used for repeated transmission of random access signals among the preamble resources of the corresponding RO resource. For example, if the first RO resource is a 4-step RACH RO resource, then the first preamble resource set for the first RO resource includes the preamble resources that can be used for repeated transmission of random access signals among all the preamble resources corresponding to the 4-step RACH RO resource.

[0052] In one implementation, different numbers of repetitions correspond to a first preamble resource set that does not overlap with each other.

[0053] It should be understood that the repetition number M1 corresponding to the first RO resource is used to indicate that the first RO resource can be used for M1 random access signal repetition transmissions. M1 can be set according to actual needs, such as 2 times, 4 times, etc. For simplicity, the following embodiments will use 2 random access signal repetition transmissions and 4 random access signal repetition transmissions as examples for illustration.

[0054] It should be understood that each first RO resource can correspond to only one repetition or multiple repetitions simultaneously.

[0055] It should be understood that the first identification information corresponding to the first RO resource can be the first identification information configured separately for each first RO resource, or it can be a unified identification information configured only for the first RO resource set. The unified identification information includes the first identification information corresponding to the first RO resource determined according to the number of the first RO resource in the first RO resource set. For example, if the identification information configured for the first RO resource set is mask information, different masks are used to indicate different subsets of RO resources. For example, Mask0 is defined as the first RO resource with an even number, which is the first identification information corresponding to the first RO resource with an even number, and Mask1 is defined as the first RO resource with an odd number, which is the first identification information corresponding to the first RO resource with an odd number.

[0056] In one implementation, the first identification information can be used to indicate the number of repetitions corresponding to the first RO resource, for example, such as Figure 5 As shown, the first RO resource set includes resources related to SSB. i The corresponding eight first RO resources RO0, RO1, RO2, RO3, RO4, RO5, RO6 and RO7 are configured according to the Mask on the network side device. Mask0 indicates the even-numbered first RO resources RO0, RO2, RO4 and RO6, which are used for repeated transmission of random access signals twice. Mask1 indicates the odd-numbered first RO resources RO1, RO3, RO5 and RO7, which are used for repeated transmission of random access signals four times.

[0057] In one implementation, the first preamble resource set corresponding to the first RO resource is determined by at least one of the following: The number of first preamble resources in the first preamble resource set; The starting number (preamble index) of the first preamble resource in the first preamble resource set. The total number of the first preamble resources corresponding to the first RO resource set.

[0058] In one implementation, the first preamble resource set corresponding to the number of repetitions can be determined based on the number of repetitions corresponding to the first RO resource configured in the first message, the number of first preamble resources in the first preamble resource set corresponding to the first RO resource, the starting number of the first preamble resource in the first preamble resource set, and the first identification information. The starting number of the first preamble resource can be omitted except in the first first preamble resource set, which must be configured there. The first identification information can also be omitted.

[0059] In another implementation, the following can be configured in the first message: the number of repetitions corresponding to the first RO resource, the number of first preamble resources in the first preamble resource set corresponding to the first RO resource, and the starting number of the first preamble resource in the first preamble resource set. The starting number of the first preamble resource can be omitted except in the first first preamble resource set, which must be configured. The starting number of the second first preamble resource set is the number following the ending number of the first first preamble resource set, and so on.

[0060] In another implementation, if the first message configures the total number of first preamble resources corresponding to the first RO resource set, then for the last first preamble resource set, the number of first preamble resources corresponding to it can be omitted and implicitly determined based on the total number of first preamble resources and the number of first preamble resources in other first preamble resource sets.

[0061] It should be understood that the first message may also include the time domain information of the first RO resource in the first RO resource set, the frequency domain information of the first RO resource, and the association information between the first RO resource and the SSB.

[0062] S212, The terminal receives a second message from the network-side device, the second message being used to configure a second RO resource set for the terminal for repeated transmission of random access signals.

[0063] In one implementation, the second message may be carried by an RRC message, such as SIB1, RACHconfigcommon, etc.

[0064] In one implementation, the second message includes at least one of the following: The temporal domain information of the second RO resources in the second RO resource set; Frequency domain information of the second RO resource; The association information between the second RO resource and the SSB; The second preamble resource set corresponding to the second RO resource, the second preamble resource set including the second preamble resource for repeated transmission of random access signals.

[0065] In one implementation, the frequency domain information of the second RO resource includes at least one of the following: Frequency domain start position; Frequency domain multiplexing number.

[0066] In one implementation, if the second message does not include the frequency domain information of the second RO resource, and the second message does not explicitly display the configuration of the frequency domain information of the second RO resource, then the frequency domain information of the second RO resource reuses the frequency domain information of the first RO resource. For example, it reuses the frequency domain start position and frequency domain reuse number of the RO resource in a 4-step RACH. The specific reuse rules are predefined by the protocol or indicated in the RRC message.

[0067] In one implementation, the association information between the second RO resource and the SSB includes: The association parameter between SSB and the second RO resource (ssb-perRACH-Occasion). The SSB set corresponding to the second RO resource.

[0068] It should be understood that the association parameter is a configuration parameter used to indicate that one SSB is associated with multiple second RO resources. In one embodiment, if the second message does not include the association parameter between the SSB and the second RO resource, the association parameter between the SSB and the second RO resource may reuse the association parameter between the SSB and the first RO resource, for example, reuse the configuration parameter for the association between the SSB and the RO resource in a 4-step RACH RO resource. In one embodiment, the value of the association parameter between the SSB and the second RO resource can be redefined, configuring only one association between the SSB and the second RO resource, for example, configuring a set of candidate values, including 1, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc.

[0069] In one implementation, the SSB set corresponding to the second RO resource can be a subset of the SSB set associated with the RO resource for random access signal transmission. The valid SSB information corresponding to each second RO resource can indicate that a subset of SSBs in the SSB set associated with the RO resource for random access signal transmission corresponds to the second RO resource. The SSB subset division can be indicated by indication information, array enumeration, or a predefined protocol, dividing the SSB set associated with the first RO resource into multiple SSB subsets. For example, a cell sends R SSBs: SSB0~SSB0. R-1 Two secondary RO resources are configured for repeated transmission of random access signals: dedicated RO resource 1 and dedicated RO resource 2. Dedicated RO resource 1 is used for SSB subset 1 {SSB0~SSB}. R / 2 The random access signal is repeatedly transmitted, and dedicated RO resource 2 is used for the SSB subset 2 {SSB}. R / 2+1 ~SSB R-1 The random access signal is repeatedly transmitted. Dedicated RO resource 1 uses SSB subset 1 to perform SSB-to-second RO resource association operation; dedicated RO resource 2 uses SSB subset 2 to perform SSB-to-second RO resource association operation.

[0070] In one embodiment, the second message may further include: the number of repetitions corresponding to the second RO resource. For example, the configured set of second RO resources includes two second RO resources for repeated transmission, dedicated RO resource 1 and dedicated RO resource 2, and dedicated RO resource 1 is used for 2 repeated transmissions and dedicated RO resource 2 is used for 4 repeated transmissions.

[0071] In one implementation, the second message may further include: second identification information corresponding to the second RO resource.

[0072] In one implementation, the second identification information is used to indicate at least one of the following: The number of repetitions corresponding to the second RO resource; The SSB or set of SSBs associated with the second RO resource.

[0073] In one implementation, when the network-side device configures a first RO resource set and a second RO resource set for the terminal, step S220 includes: S221. Determine the association between the RO resources in the first RO resource set and the RO resources in the second RO resource set.

[0074] In one implementation, step S221 includes: Based on the first condition, X first RO resources in the first RO resource set and Y second RO resources in the second RO resource set are determined; wherein X and Y are positive integers.

[0075] The first condition may include at least one of the following: The first RO resource corresponds to the first SSB, and the second RO resource corresponds to the second SSB; The first RO resource and the second RO resource correspond to the same number of repetitions.

[0076] In one implementation, the first SSB and the second SSB may be the same SSB. If the random access signal repetition transmission is applied to a single SSB, then it is necessary to determine the association between the first RO resource and the second RO resource corresponding to that single SSB.

[0077] In another implementation, the first SSB and the second SSB can be the same set of SSBs. The random access signal repetition transmission can be applied to a subset of SSBs. In this case, it is necessary to determine the association between the first RO resource and the second RO resource corresponding to the subset of SSBs.

[0078] In another implementation, the first SSB and the second SSB may be different or different. The random access signal retransmission on the first RO resource is associated with the first SSB, and the random access signal retransmission on the second RO resource is associated with the second SSB. In this case, it is necessary to determine the association relationship between the first RO resource corresponding to the first SSB and the second RO resource corresponding to the second SSB.

[0079] For the sake of simplicity, the following embodiments will be illustrated by taking the first SSB and the second SSB as the same SSB.

[0080] After determining the X first RO resources and Y second RO resources, the association relationship between the X first RO resources and the Y second RO resources is determined. Specifically, the X first RO resources are first RO resources that are associated with the first SSB within an association cycle between the first RO resources in the first RO resource set and the SSB. The X second RO resources are second RO resources that are associated with the second SSB within an association cycle between the second RO resources in the second RO resource set and the SSB; or the X second RO resources are second RO resources that are associated with the second SSB within an association cycle between the second RO resources in the second RO resource set and the SSB, within one RO time resource. Further optionally, X first RO resources and Y second RO resources for N random access signal repetitions are determined, that is, X first RO resources are selected from the set of first RO resources supporting N random access signal repetitions, and Y second RO resources are selected from the set of second RO resources supporting N random access signal repetitions.

[0081] The relationship can be determined in various ways. In one implementation, the relationship between the X first RO resources and the Y second RO resources is determined by at least one of the following methods: Determined according to predefined mapping rules; It is determined based on the first mapping information that the first mapping information is carried in the first configuration information.

[0082] In one implementation, the predefined mapping rule may be related to the correspondence between the frequency domain reuse number of the first RO resource and the frequency domain reuse number of the second RO resource.

[0083] The frequency domain reuse count of the second RO resource may be less than that of the first RO resource. Multiple first RO resources need to be associated with one second RO resource. Considering that the proportion of terminals that need to perform repeated transmission of random access signals is relatively small compared to the total number of terminals in the cell, and assuming approximately the same collision probability, the frequency resources required by the second RO resource are relatively smaller, thereby improving the utilization efficiency of the second RO resource.

[0084] In one implementation, X first RO resources can be associated with Y second RO resources according to the principle of uniform mapping, wherein each second RO resource is associated with... or Each first RO resource, or each first RO resource associated with or A second RO resource. Among them, The floor function is the floor function. This is the floor function. The specific mapping method can be to divide the X first RO resources into Y groups, each associated with one of the Y second RO resources; or, to map them cyclically to the Y second RO resources according to their RO number order. For example... Figure 6 As shown, it is determined that there is an SSB. i The corresponding 8 first RO resources RO0~RO7, and the SSB i The two corresponding second RO resources, RO8 and RO9, are then associated with RO8 and RO4 to RO7 according to the principle of uniform distribution.

[0085] In one implementation, step S221 further includes: Determine the association between the first preamble resource set corresponding to the first RO resource in the first RO resource set and the second preamble resource set corresponding to the second RO resource in the second RO resource set; The first preamble resource set includes preamble resources on the first RO resource used for repeated transmission of random access signals; the second preamble resource set includes preamble resources on the second RO resource used for repeated transmission of random access signals.

[0086] There are multiple ways to determine the association between the first preamble resource set and the second preamble resource set. This application embodiment only provides one specific implementation method, which is determined by the following method: Based on the second numbering order of the second preamble resource and the first numbering order of the first preamble resource, starting from the target second preamble resource, the second preamble resource is sequentially associated with the first preamble resource; The second numbering order is determined based on the number of the second preamble resource in the second preamble resource set, and the first numbering order is determined based on the RO number size of the associated first RO resource and the preamble number size of the first preamble resource in the first preamble resource set.

[0087] Based on the RO numbers of the first RO resources from low to high, and the preamble numbers of the corresponding first preamble resources in the first preamble resource set from low to high, these are mapped to the second preamble resources in the second preamble resource set corresponding to the second RO resources. For example... Figure 6 As shown, if the first preamble resource set corresponding to each first RO resource includes n first preamble resources, then the first preamble resources in the first preamble resource set corresponding to RO0~RO3 can be sorted to obtain the first numbered preamble number 0~4n-1, and a sulfur crosslinking relationship can be established with the second preamble resource in the second preamble resource set corresponding to RO8.

[0088] It should be understood that the target second preamble resource is the first second preamble resource in the second preamble resource set, and by default it is the second preamble resource with the number 0.

[0089] In one implementation, the association between the X first RO resources and the Y second RO resources can also be displayed based on the first mapping information carried in the first configuration information. For example, the first mapping information can be first identification information corresponding to the first RO resource and second identification information corresponding to the second RO resource. Then, the first RO resources and the second RO resources corresponding to the first identification information and the second identification information can be associated based on the first identification information and the second identification information, for example.

[0090] In one implementation, the first mapping information is used to indicate at least one of the following: The association information between the first SSB and the second SSB can be, for example, the same SSB, the same subset of SSBs, or different combinations of SSBs; The relationship between the X first RO resources and the Y second RO resources; The target is the second preamble resource.

[0091] In another implementation, the predefined mapping rule can be related to the correspondence between the time-domain position of the first RO resource (after time-domain amplification or extension) and the time-domain position of the second RO resource. That is, the time-domain resource usage of the second RO resource is determined to be S times that of the first RO resource. Specifically, the configuration can be based on the time-domain resource configuration parameters of the first RO resource, with additional configuration of time slot offset or scaling factor of the RO resource period to obtain the second RO resource with a speed of S times.

[0092] In one implementation, the first RO resource and the second RO resource have a 1-to-S relationship, and the configuration period of the first RO resource includes S times the number of the second RO resources.

[0093] In one implementation, the first RO resource is associated with S consecutive second RO resources in the time domain. The SSB associated with the S consecutive second RO resources in the time domain is consistent with that of the first RO resource.

[0094] The SSB-to-second RO resource association pattern of the first RO resource is repeated S times on the second RO resource. The terminal selects the RO resources in the association pattern of the second RO resources that are in the same position as the first RO resource as the S second RO resources associated with the first RO resource.

[0095] The second RO resource corresponds one-to-one with the second preamble set of the first RO resource, which is used for repeated random access signal transmissions. They have the same preamble index.

[0096] It should be understood that during the association process between the second RO resource and the first RO resource, additional second configuration mapping information may be used. This second configuration mapping information may be time-domain related and used to indicate that a time-domain subset of the first RO resource is associated with the second RO resource.

[0097] It should be understood that the determination of the association relationship between RO resources in the first RO resource set can be implemented in multiple ways. It can be determined according to predefined mapping rules or through association identification information. Specifically, it involves determining X RO resources in the first association cycle and X RO resources in the second association cycle, where the first and second association cycles are association cycles at different times within the first RO resource set; the X RO resources in the first association cycle and the X RO resources in the second association cycle are associated with the same SSB; establishing a mapping relationship for RO resources with the same number according to predefined mapping rules; or, using association identification information, such as RO number offsets, to determine the mapping relationship between the X RO resources in the first association cycle and the X RO resources in the second association cycle; and establishing a mapping relationship for the same preamble among the X RO resources in the first association cycle and the X RO resources in the second association cycle.

[0098] It should be understood that the determination of the association relationship between RO resources in the first RO resource set can be implemented in multiple ways, such as according to predefined mapping rules or through association identification information. One approach is to determine the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle, where the third and fourth association cycles are association cycles at different times in the second RO resource set; or to determine the Y RO resources in the first RO time resource and the Y RO resources in the second RO time resource set, where the first and second RO time resources are RO time resources at different times in the second RO resource set; the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle are associated with the same SSB; according to predefined mapping rules, RO resources with the same number establish a mapping relationship; or, using association identification information, such as RO number offset, to determine the mapping relationship between the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle; and to establish a mapping relationship between the same preamble among the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle.

[0099] In one implementation, step S220 may further include: The relationships between RO resources in the first RO resource set can be determined by at least one of the following: The first identification information corresponding to the RO resource; The number of times the RO resource is reused; The RO resource corresponds to the SSB.

[0100] For example, the first RO resources that correspond to the same SSB and have the same number of reuses can be associated.

[0101] In one implementation, step S220 may further include: Determining the relationships between RO resources in the second RO resource set can be achieved by at least one of the following: The second identification information corresponding to the RO resource; The number of times the RO resource is reused; The SSB corresponding to the RO resource.

[0102] For example, a second RO resource that corresponds to the same SSB and has the same number of reuses can be associated.

[0103] In one embodiment, prior to step S230, the method further includes: If the first condition is met, the terminal determines to perform repeated transmission of random access signals; The first condition includes at least one of the following: The signal quality of the third SSB is lower than the first threshold T0, and the third SSB is an SSB used for repeated transmission of random access signals; The number of failed attempts to execute the random access procedure has reached the second threshold.

[0104] It should be understood that the third SSB may be an SSB selected by the terminal based on the signal quality of each SSB.

[0105] The terminal can detect the signal quality of the third SSB, such as downlink path loss reference or RSRP. When the signal quality of the third SSB is lower than a first threshold T0, the terminal determines to perform repeated random access signal transmission. Alternatively, after performing random access signal transmission and failing M times, the terminal determines to perform repeated random access signal transmission, wherein the failure to receive the Msg2 message after performing random access signal transmission can be considered as a failure of random access signal transmission.

[0106] In one implementation, step S230 includes: S231. The terminal determines the number of repetitions based on the signal quality of the third SSB.

[0107] In one implementation, the terminal can set A-1 first thresholds T1 to obtain A threshold intervals, with each threshold interval corresponding to an A number of repetitions based on the SSB signal quality. The signal quality of each SSB, such as RSRP, is compared sequentially with the A-1 first thresholds T1. An SSB exceeding the first threshold T1 is selected as the third SSB, or the SSB with the best signal quality is selected as the third SSB, and the repetition count corresponding to the threshold interval exceeding the first threshold T1 is used as the repetition count for this random access signal retransmission. If multiple SSBs meet the above conditions, one SSB can be randomly selected as the third SSB; if no SSB's signal quality exceeds any first threshold T1, the maximum repetition count configured by the network is used for random access signal retransmission. Alternatively, an SSB combination can be selected from several SSB combinations configured by the network as the third SSB, where at least one SSB in the SSB combination has a signal quality exceeding the first threshold T1.

[0108] S232. Based on the third SSB and the number of times the random access signal is repeated, and the association between the first RO resource set and / or the second RO resource set, determine N RO resources.

[0109] The first RO resource and / or the second RO resource used to perform this random access signal repetition transmission are determined from the first RO resource set and / or the second RO resource set, as well as the corresponding first preamble resource set and / or the second preamble resource set.

[0110] S233. Perform N random access signal repetitions using the N RO resources.

[0111] In one implementation, the repeated transmission of random access signals can be completed within one or more time units. These time units can be the association cycle, association period, or association pattern period of a 4-step RACH associated SSB to RO resource. For example, if one PRACH association cycle contains *a* SSB-to-first RO resource mapping cycles and *b* SSB-to-second RO resource mapping cycles, then one PRACH association cycle can support less than or equal to *a+b* repeated transmissions of random access signals. If the number of repeated transmissions of the random access signal is *c*, then the consecutive PRACH association cycles occupied by the repeated transmission of the random access signal are... The first association period of multiple consecutive PRACH association periods is calculated from the reference association period defined by the protocol, for example, the consecutive PRACH association periods used for repeated transmission of random access signals are divided with the PRACH association period starting with radio frame 0.

[0112] The terminal begins random access signal repetition transmission with the first RO resource that meets the first condition within the time unit. The first condition may be the first RO resource that supports N random access signal repetition transmissions associated with the third SSB within the time unit; or the first RO resource or the second RO resource that supports N random access signal repetition transmissions associated with the third SSB within the time unit.

[0113] It is understandable that the N random access signal repetitions are determined by the association between the first RO resource and the second RO resource using a preamble.

[0114] In one implementation, the time span for repeated transmission of random access signals should not exceed a preset time limit, which can be a PRACH association cycle, a PRACH association period, or a PRACH association pattern period. The system can determine the maximum number of repeated transmissions of random access signals supported based on the number of first RO resources and second RO resources existing within the time range corresponding to the time limit.

[0115] After repeatedly transmitting the random access signal, the terminal needs to open a RAR listening window to listen for RARs sent from the network-side device. There are multiple ways to open the RAR listening window; this application only provides a few specific implementation methods for illustrative purposes.

[0116] In one implementation, the terminal can open a RAR listening window after each random access signal transmission. The length of the listening window can be configured by the RRC message. If the listening window does not receive a RAR and the number of times the random access signal is repeatedly transmitted has not reached the required number of repetitions, the random access signal is retransmitted on the next determined first RO resource or second RO resource. If the number of times the transmitted random access signal is repeatedly transmitted has reached the required number of repetitions, the random access signal transmission is considered to have failed, the failure counter for the random access signal transmission is incremented, and automatic backoff is performed.

[0117] In another implementation, the terminal can open the RAR listening window after completing N random access signal retransmissions. If the listening window does not receive RAR, it is considered that the random access signal retransmission has failed, the failure counter of the random access signal transmission is incremented by one, and automatic backoff is performed.

[0118] As can be seen from the technical solutions in the above embodiments, in this application embodiment, when the network-side device configures a first RO resource set and a second RO resource set for the terminal, the terminal determines X first RO resources in the first RO resource set and Y second RO resources in the second RO resource set according to a first condition; then it determines the association relationship between the X first RO resources and the Y second RO resources, thereby supporting the repeated transmission of random access signals with a larger number of repetitions, obtaining better diversity gain, and enabling the system to efficiently utilize RO resources through different combinations of RO resources.

[0119] Based on the above embodiments, further, as Figure 6As shown, the second RO resource set is located in a separately configured BandWidth Part (BWP).

[0120] It should be understood that the separately configured BWP is an uplink BWP (UL BWP), which is only used to configure the second RO resource set. That is, the network-side device only configures the second RO resource set for the terminal. Therefore, there is no relationship between the RO resources in the first RO resource set and the second RO resource set.

[0121] The terminal determines whether to perform repeated transmission of random access signals by detecting the channel quality of the third SSB. Specifically, repeated transmission of random access signals is performed when the channel quality of the third SSB is lower than a first threshold T0. If the terminal performs repeated transmission of random access signals, the terminal is switched to the separately configured UL BWP; otherwise, it operates on the regular UL BWP for random access signal transmission.

[0122] The terminal needs to determine the relationships between RO resources in the second RO resource set, which can be determined by at least one of the following: The second identification information corresponding to the RO resource; The number of times the RO resource is reused; The SSB corresponding to the RO resource.

[0123] In one implementation, the network-side device configures the frequency domain reuse number F of the RO resource and the association parameter L between the SSB and the second RO resource, and This allows k consecutive second RO resources in the time domain to be associated with the same SSB. The terminal can utilize the second RO resources to achieve no more than k repeated transmissions of random access signals.

[0124] As can be seen from the technical solutions in the above embodiments, the embodiments of this application configure a second RO resource set on a separately configured BWP for the terminal through the network-side device, which is used for repeated transmission of random access signals, thereby supporting repeated transmission of random access signals with a larger number of repetitions and obtaining better diversity gain.

[0125] The random access resource configuration method provided in this application can be executed by a random access resource configuration device. This application uses the execution of the random access resource configuration method by a random access resource configuration device as an example to illustrate the random access resource configuration device provided in this application.

[0126] like Figure 7 As shown, the random access resource configuration device includes: a receiving module 701, an association module 702, and a transmission module 702.

The first RO resource set may include RO resources for 4-step RACH, RO resources for 2-step RACH, or RO resources for 4-step RACH with Msg3 repeated transmission. The second RO resource set includes dedicated RO resources. Then, the association relationship of RO resources in the first RO resource set and / or the second RO resource set is determined. Then, N RO resources are determined according to the association relationship of RO resources in the first RO resource set and / or the second RO resource set to perform N repeated transmissions of random access signals. This can support repeated transmissions of random access signals with a larger number of repetitions, obtain better diversity gain, and enable the system to efficiently utilize RO resources through different combinations of RO resources.

[0130] Based on the above embodiments, the association module 702 is further configured to: Based on the first condition, determine X first RO resources in the first RO resource set and Y second RO resources in the second RO resource set; Determine the association relationship between the X first RO resources and the Y second RO resources; The first condition includes at least one of the following: The first RO resource corresponds to the first SSB, and the second RO resource corresponds to the second SSB; The first RO resource and the second RO resource correspond to the same number of repetitions; X and Y are positive integers.

[0134] Furthermore, each of the second RO resources is associated with or Each first RO resource, or each first RO resource associated with or A second RO resource.

[0135] Furthermore, the association module 702 is used for: Based on the second numbering order of the second preamble resource and the first numbering order of the first preamble resource, starting from the target second preamble resource, the second preamble resource is sequentially associated with the first preamble resource; The second numbering order is determined based on the number of the second preamble resource in the second preamble resource set, and the first numbering order is determined based on the RO number size of the associated first RO resource and the preamble number size of the first preamble resource in the first preamble resource set.

[0136] Furthermore, the target second preamble resource is the first second preamble resource in the second preamble resource set.

[0140] Furthermore, the receiving module 701 is configured to perform at least one of the following: The terminal receives a first message from the network-side device, the first message being used to configure a first RO resource set for random access signal repetition transmission for the terminal. The terminal receives a second message from the network-side device, the second message being used to configure a second RO resource set for random access signal repetitive transmission.

[0141] Furthermore, the first message includes at least one of the following: A first preamble resource set corresponding to the first RO resource in the first RO resource set, wherein the first preamble resource set includes a first preamble resource for repeated transmission of random access signals; The number of repetitions corresponding to the first RO resource; The first identifier information corresponding to the first RO resource.

[0142] Furthermore, the first identification information is used to indicate the number of repetitions corresponding to the first RO resource.

[0143] Furthermore, different numbers of repetitions correspond to the first preamble resource sets that do not overlap with each other.
