Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This invention claims priority to a Chinese patent application submitted to the China Patent Office on April 2, 2022, bearing application number 202210346938.3 and titled "Random access resource configuration method, apparatus, terminal and network side equipment", the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the mobile communication technology field, and specifically to a random access resource configuration method, device, terminal and network side equipment. [Background technology]

[0003] The coverage performance of uplink signals in the random access process in a New Radio (NR) system, such as message 1 (Msg1) in the 4-step random access channel (RACH) process, is relatively poor compared to the coverage performance of other channels, so it is necessary to introduce repeated transmission of Msg1 in the physical random access channel (PRACH) to improve the coverage performance of Msg1.

[0004] The optional values ​​of the association period between a Synchronization Signal Block (SSB) and a Random Access Occasion (RACH Occasion) may be 10ms, 20ms, 40ms, 80ms and 160ms. The length of the corresponding Random Access Response (RAR) monitoring window is up to 10ms. Therefore, the time length of the association period may be longer than the time length of the RAR monitoring window. In such a case, if the repeated transmission of Msg1 is still realized by using RO in multiple association periods, the time interval for each transmission of Msg1 is larger than the RAR monitoring window. If repeated transmission of Msg1 is performed using only conventional PRACH resources, the transmission time interval of Msg1 is too long, which is equivalent to repeatedly performing a single transmission of Msg1 multiple times, resulting in a long delay in the terminal access flow. If the transmission interval is too long, it may affect the diversity gain of repeated transmission of Msg1. When transmitting Msg1, an appropriate downlink reference beam is selected based on the SSB Reference Signal Received Power (RSRP). If the time interval is too long, the validity of the downlink parameter beam will expire.

[0005] The conventional RO resource does not support repeated transmission of a random access signal multiple times, and cannot effectively increase the diversity gain through repeated transmission. Summary of the Invention [Problem to be solved by the invention]

[0006] The embodiments of the present application provide a method, device, terminal and network side device for configuring a random access resource, which can solve the problem that the conventional RO resource does not support repeated transmission of a random access signal multiple times, and the diversity gain caused by repeated transmission cannot be effectively increased.

[0025] In the following, the random access resource configuration method, apparatus, terminal and network side equipment according to the embodiments of the present application will be described in detail through several embodiments and application scenarios thereof in conjunction with the drawings.

[0026] As shown in Figure 2, an embodiment of the present application provides a random access resource configuration method, and the execution body of the method is a terminal, in other words, the method may be executed by software or hardware installed in the terminal. The method includes the following steps:

[0027] S210, the terminal receives first configuration information for configuring a first RO resource set and / or a second RO resource set in which the random access signal is repeatedly transmitted from a network side device.

[0028] Wherein, the first RO resource set comprises: 4-step RACH RO resources and Two-step random access (2-step RACH) RO resources and and the RO resource of a 4-step RACH for which message 3 (Msg3) is repeatedly transmitted (for requesting Msg3 repetition).

[0029] It should be understood that the repeated transmission of the random access signal may be repeated transmission of Msg1 of a 4-step RACH, and the first RO resource set and the second RO resource set include RO resources that can be used to perform repeated transmission of Msg1 of a 4-step RACH.

[0030] It should be understood that the RO resource on which the random access signal is repeatedly transmitted may be multiplexed with at least one of the RO resources of 4-step RACH, the RO resources of 2-step RACH, or the RO resources on which Msg3 is repeatedly transmitted. The first RO resource set may be obtained by dividing a preamble resource set corresponding to the at least one RO resource. For example, when the terminal supports 4-step RACH and configures RO resources of 4-step RACH, the first RO resource set may include RO resources of 4-step RACH, and the preamble corresponding to the RO resources of 4-step RACH as the first RO resource in the first RO resource set may be used for the repeated transmission of the random access signal, i.e., the repeated transmission of Msg1. When the terminal supports 2-step-RACH and configures RO resources of 2-step RACH, the first RO resource set may further include RO resources of 2 ...2-step RACH as the first RO resource in the first RO resource set may be used for the repeated transmission of the random access signal, i.e., the repeated transmission of Msg1. The preamble resource corresponding to the RO resource of the RACH may be used for repeated transmission of a random access signal, i.e., repeated transmission of Msg1. When the terminal supports repeated transmission of Msg3 and configures an RO resource for repeatedly transmitting Msg3, the first RO resource set may further include an RO resource for repeatedly transmitting Msg3. The preamble resource corresponding to the RO resource for repeatedly transmitting Msg3 as the first RO resource in the first RO resource set may be used for repeated transmission of a random access signal, i.e., repeated transmission of Msg1.

[0031] The network side device may configure a corresponding first RO resource set for each RO resource.

[0032] In one embodiment, the network side device may configure a first RO resource set including RO resources of a 4-step RACH and / or a second RO resource set including dedicated RO resources for the terminal.

[0033] In another embodiment, the network side device may configure the terminal with a first RO resource set including RO resources of a 2-step RACH and / or a second RO resource set including dedicated RO resources.

[0034] In another embodiment, the network side device may configure a first RO resource set including an RO resource on which Msg3 is repeatedly transmitted to the terminal and / or a second RO resource set including a dedicated RO resource.

[0035] In another embodiment, the network side device may simultaneously configure, for the terminal, a first RO resource set including an RO resource for a 4-step RACH and an RO resource on which Msg3 is repeatedly transmitted, and / or a second RO resource set including a dedicated RO resource.

[0036] As shown in FIG. 3, optionally, the network side device separates a first RO resource set used for repeatedly transmitting Msg1 into a set of RO resources of 4-step RACH, RO resources of 2-step RACH, and RO resources for repeatedly transmitting Msg3, and configures corresponding repetition numbers N0, N1, and N2 for each first RO resource, where N0, N1, and N2 may be the same or different.

[0037] However, for the sake of simplicity, in the following embodiments, an example is described in which the network side device configures a first RO resource set including a 4-step RACH RO resource and / or a second RO resource set including a dedicated RO resource for the terminal.

[0038] The second RO resource set includes dedicated RO resources that are only used for repeated transmission of a random access signal.

[0039] 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 according to actual needs, where the first message is used to configure a first RO resource set for the terminal, while the second message is used to configure a second RO resource set for the terminal.

[0040] S220, the terminal determines an association relationship of RO resources in the first RO resource set and / or the second RO resource set.

[0041] Further, step S220 Association relationships between RO resources in the first RO resource set; and association relationships between RO resources in the second RO resource set; Determining at least one association relationship between RO resources in the first RO resource set and the second RO resource set.

[0042] It should be understood that the manner of determining the association relationship may have various implementation manners, and may be determined based on a predefined mapping criteria (also called association criteria), or may be determined by association identifier information. The association relationship may be used to indicate the existence of an associated RO resource, and may represent association information of the RO resource in which the association relationship exists, for example, when used in the same repeated transmission of Msg1, it corresponds to the same repetition number, or corresponds to the same SSB or SSB set, etc.

[0043] S230, the terminal determines N RO resources based on an association relationship of RO resources in the first RO resource set and / or the second RO resource set to perform N repeated transmissions of a random access signal, where N is a positive integer.

[0044] The terminal may determine N RO resources suitable for the repeated transmission of the current random access signal from the first RO resource and / or the second RO resource having an association, and perform N repeated transmissions of the random access signal.

[0045] The N times repeated transmission of the random access signal is to perform random access signal transmission in N RO resources, respectively. For example, Msg1 carrying a preamble corresponding to the repeated transmission of Msg1 may be transmitted in N first RO resources (4-step RACH RO resources), respectively.

[0046] It should be understood that when the network side device configures only a first RO resource set for the terminal, the N repeated transmissions of the random access signal performed by the terminal are all on the first RO resource; when the network side device configures only a second RO resource set for the terminal, the N repeated transmissions of the random access signal performed by the terminal are all on the second RO resource; when the network side device configures a first RO resource set and a second RO resource set for the terminal, among the N repeated transmissions of the random access signal performed by the terminal, N1 times are on the first RO resource and N2 times are on the second RO resource, where N1+N2=N, where N1 and N2 are integers greater than or equal to 0.

[0047] As can be seen from the technical solutions of the above embodiments, in the random access resource configuration method according to the embodiments of the present application, a network side device receives first configuration information for configuring a first RO resource set and / or a second RO resource set in which a random access signal is repeatedly transmitted, where the first RO resource set may include RO resources of a 4-step RACH, RO resources of a 2-step RACH, or RO resources of a 4-step RACH in which Msg3 is repeatedly transmitted, and the second RO resource set includes a dedicated RO resource, and further determines an association relationship of RO resources in the first RO resource set and / or the second RO resource set, and determines N RO resources according to the association relationship of RO resources in the first RO resource set and / or the second RO resource set to perform N times of repeated transmission of the random access signal, so as to support repeated transmission of the random access signal with more repetitions, complete the repeated transmission of the random access signal within a shorter time, obtain better diversity gain, and enable the system to efficiently utilize RO resources through the combination of different RO resources.

[0048] Based on the above embodiment, an example of an embodiment for implementing the invention is further described in which the network side device configures a first RO resource set and a second RO resource set for the terminal. As shown in FIG. 4, step S210 includes the following steps:

[0049] S211, the terminal receives a first message from the network side device for configuring a first RO resource set used for repeatedly transmitting a random access signal to the terminal.

[0050] In one embodiment, the first message may be carried in a Radio Resource Control (RRC) message, such as a System Information Block (SIB) 1, Random Reception Channel configuration message RACHconfigcommon.

[0051] In one embodiment, the first message comprises: A first preamble resource set corresponding to a first RO resource in the first RO resource set, the first preamble resource including a first preamble resource used for repeatedly transmitting a random access signal; A repetition count M1 corresponding to the first RO resource; and first identifier information corresponding to the first RO resource.

[0052] It should be understood that the first RO resource in the first RO resource set may be at least one of the RO resources of a 4-step RACH, the RO resources of a 2-step RACH, or the RO resources of a 4-step RACH on which Msg3 is repeatedly transmitted. The first RO resource set may be a part or all of the RO resources of any one of the above RO resources, that is, the first RO resource set may include at least one of the RO resources of all or a part of the RO resources of a 4-step RACH, the RO resources of all or a part of the RO resources of a 2-step RACH, or the RO resources of a 4-step RACH on which Msg3 is repeatedly transmitted.

[0053] It should be understood that the first preamble resource set configured for the first RO resource includes preamble resources used for repeated transmission of a random access signal among preamble resources corresponding to the RO resource. For example, when the first RO resource is a RO resource of a 4-step RACH, the first preamble resource set of the first RO resource includes preamble resources that can be used for repeated transmission of a random access signal among all preamble resources corresponding to the RO resource of the 4-step RACH.

[0054] In one embodiment, the different iterations correspond to non-overlapping sets of first preamble resources.

[0055] 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 to repeatedly transmit a random access signal M1 times, and the M1 can be set according to actual needs, such as 2 times, 4 times, etc. For convenience, the following embodiments will take the repeated transmission of a random access signal 2 times and the repeated transmission of a random access signal 4 times as examples.

[0056] It should be understood that each first RO resource may correspond to only one iteration number, or may correspond to multiple iteration numbers at the same time.

[0057] It should be understood that the first identifier information corresponding to the first RO resource may be first identifier information respectively configured for each first RO resource, or may be one unified identifier information configured only for the first RO resource set, and the unified identifier information includes first identifier 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, when the identifier information configured in the first RO resource set is mask code information, different mask codes indicate different RO resource subsets. For example, Mask0 is defined as the first RO resource with an even number, i.e., the first identifier information corresponding to the first RO resource with an even number, and Mask1 is defined as the first RO resource with an odd number, i.e., the first identifier information corresponding to the first RO resource with an odd number.

[0058] In one embodiment, the first identifier information may be used to indicate the number of repetitions corresponding to the first RO resources. For example, as shown in FIG. 5, the first RO resource set includes eight first RO resources RO0, RO1, RO2, RO3, RO4, RO5, RO6 and RO7 corresponding to SSBi. Based on a Mask configured by a network side device, Mask0 indicates the even-numbered first RO resources RO0, RO2, RO4 and RO6 and is used for repeated transmission of a random access signal that is repeated twice, and Mask1 indicates the odd-numbered first RO resources RO1, RO3, RO5 and RO7 and is used for repeated transmission of a random access signal that is repeated four times.

[0059] In one embodiment, the first preamble resource set corresponding to the first RO resource includes: the number of first preamble resources in the first preamble resource set; A starting number (preamble index) of a first preamble resource in the first preamble resource set; and a total number of first preamble resources corresponding to the first RO resource set.

[0060] In one embodiment, the first preamble resource set corresponding to the repetition number may be determined based on a repetition number corresponding to the first RO resource configured in the first message, a number of first preamble resources in a first preamble resource set corresponding to the first RO resource, a starting number of the first preamble resource in the first preamble resource set, and first identifier information, where the starting number of the first preamble resource must be configured in the first first preamble resource set, and may be default, and the first identifier information may also be default.

[0061] In another embodiment, it may be 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, and the starting number of the first preamble resource in the first preamble resource set, where the starting number of the first preamble resource must be configured in the first first preamble resource set, and may be default, and the starting number of the second first preamble resource set is the next number of the ending number of the first first preamble resource set, and inferred on this basis.

[0062] In another embodiment, when the first message is configured with a total number of first preamble resources corresponding to the first RO resource set, for the last first preamble resource set, the number of corresponding first preamble resources may be a default and is implicitly determined based on the total number of first preamble resources and the number of first preamble resources in the other first preamble resource sets.

[0063] It should be understood that the first message may further include: time domain information of a first RO resource in the first RO resource set, frequency domain information of the first RO resource, and association information of the first RO resource with an SSB.

[0064] S212, the terminal receives a second message from the network side device, for configuring a second RO resource set used for repeatedly transmitting a random access signal to the terminal.

[0065] In one embodiment, the second message may be carried by an RRC message, such as SIB1, RACHconfigcommon, etc.

[0066] In one embodiment, the second message comprises: time domain information of a second RO resource in the second RO resource set; Frequency domain information of the second RO resource; and Association information between the second RO resource and an SSB; a second preamble resource set including a second preamble resource used for repeated transmission of a random access signal, the second preamble resource set corresponding to the second RO resource.

[0067] In one embodiment, the frequency domain information of the second RO resource comprises: A frequency domain start position; and a frequency domain multiplexing number.

[0068] In one embodiment, if the second message does not include frequency domain information of the second RO resource, the frequency domain information constituting the second RO resource is not indicated in the second message, and then the frequency domain information of the second RO resource is multiplexed with the frequency domain information of the first RO resource, for example, the frequency domain start position and frequency domain multiplexing number of the RO resource of 4-step RACH. A specific multiplexing rule is predefined by a protocol or indicated in an RRC message.

[0069] In one embodiment, the association information between the second RO resource and the SSB includes: An association parameter (ssb-perRACH-Occasion) from the SSB to the second RO resource; and an SSB set corresponding to the second RO resource.

[0070] It should be understood that the association relationship parameter is a configuration parameter for instructing that one SSB is associated with multiple second RO resources. In one embodiment, when the second message does not include the SSB to the second RO resource association relationship parameter, the SSB to the second RO resource association relationship parameter multiplexes the SSB to the first RO resource association relationship parameter, for example, multiplexes the SSB to RO resource association configuration parameter of the RO resource of 4-step RACH. In one embodiment, the value of the SSB to the second RO resource association relationship parameter may be redefined to configure only one association situation from the SSB to the second RO resource, for example, a candidate value set including 1, 1 / 2, 1 / 4, 1 / 8, 1 / 16, etc.

[0071] In one embodiment, the SSB set corresponding to the second RO resource may be a subset of the SSB set associated with the RO resource for random access signal transmission, and the SSB validity information corresponding to each second RO resource may indicate that one SSB subset of the SSB sets associated with the RO resource for random access signal transmission corresponds to the second RO resource. The SSB subset division method may divide the SSB set associated with the first RO resource into a plurality of SSB subsets by indication by indication information, enumeration of an array, or a predefined protocol. For example, one cell transmits R SSBs: SSB0 to SSBR-1, and two second RO resources used for repeated transmission of random access signals are configured, which are dedicated RO resource 1 and dedicated RO resource 2. The dedicated RO resource 1 is used for repeated transmission of random access signals of SSB subset 1 {SSB0 to SSBR / 2}, and the dedicated RO resource 2 is used for repeated transmission of random access signals of SSB subset 2 {SSBR / 2+1 to SSBR-1}. The dedicated RO resource 1 performs an association operation from the SSB to the second RO resource using the SSB subset 1, and the dedicated RO resource 2 performs an association operation from the SSB to the second RO using the SSB subset 2.

[0072] In one embodiment, the second message may further include a repetition number corresponding to the second RO resource, for example, the configured second RO resource set includes two second RO resources used for repeated transmission, namely, dedicated RO resource 1 and dedicated RO resource 2, and the dedicated RO resource 1 is used for two repeated transmissions, and the dedicated RO resource 2 is used for four repeated transmissions.

[0073] In one embodiment, the second message may further include second identifier information corresponding to the second RO resource.

[0074] In one embodiment, the second identifier information comprises: a number of iterations corresponding to the second RO resource; and The second RO resource may be used to indicate at least one of an SSB or an SSB set associated with the second RO resource.

[0075] In one embodiment, when the network side device configures the terminal with a first RO resource set and a second RO resource set, step S220 includes the following steps:

[0076] S221, determining an association relationship between RO resources in the first RO resource set and the second RO resource set.

[0077] In one embodiment, step S221 includes: The method includes determining, according to a first condition, X first RO resources in a first RO resource set and Y second RO resources in a second RO resource set, where X and Y are positive integers.

[0078] The first condition is: The first RO resource corresponds to a first SSB and the second RO resource corresponds to a second SSB; the first RO resource and the second RO resource correspond to the same number of repetitions.

[0079] In one embodiment, the first SSB and the second SSB may be the same SSB, and if the repeated transmission of the random access signal is used for a single SSB, it is necessary to determine an association relationship between the first RO resource and the second RO resource corresponding to the single SSB.

[0080] In another embodiment, the first SSB and the second SSB may be SSBs of the same group, and if the repeated transmission of the random access signal may be used for one SSB subset, it is necessary to determine an association relationship between the first RO resource and the second RO resource corresponding to this one SSB subset.

[0081] In another embodiment, the first SSB and the second SSB may be the same or different, and the repeated transmission of the random access signal on the first RO resource of the repeated transmission of the random access signal is associated with the first SSB, and the repeated transmission of the random access signal on the second RO resource of the repeated transmission of the random access signal is associated with the second SSB, and then it is necessary to determine an association relationship between the first RO resource corresponding to the first SSB and the second RO resource corresponding to the second SSB, respectively.

[0082] For simplicity, in the following embodiments, the first SSB and the second SSB are the same SSB.

[0083] After determining the X first RO resources and the Y second RO resources, determine an association relationship between the X first RO resources and the Y second RO resources. Specifically, the X first RO resources are first RO resources within one association cycle between a first RO resource in the first RO resource set and an SSB and associated with a first SSB. The X second RO resources are second RO resources within one association cycle between a second RO resource in the second RO resource set and an SSB and associated with a second SSB, or the X second RO resources are second RO resources within one association cycle between a second RO resource in the second RO resource set and an SSB, within one RO time resource, and associated with a second SSB. Further optionally, determine X first RO resources used for N repeated transmissions of the random access signal and Y second RO resources used for N repeated transmissions of the random access signal, i.e., select X first RO resources from a first RO resource set supporting N repeated transmissions of the random access signal, and select Y second RO resources from a second RO resource set supporting N repeated transmissions of the random access signal.

[0084] The manner of determining the association relationship may be various implementation manners. In one embodiment, the association relationship between the X number of first RO resources and the Y number of second RO resources is as follows: based on predefined mapping rules; and based on first mapping information carried in the first configuration information.

[0085] In one embodiment, the predefined mapping rule may be associated with a correspondence relationship between a frequency domain multiplexing number of the first RO resource and a frequency domain multiplexing number of the second RO resource.

[0086] The frequency domain multiplexing number of the second RO resource may be smaller than the frequency domain multiplexing number of the first RO resource. A plurality of first RO resources need to establish an association relationship with one second RO resource. Considering that the proportion of terminals that need to perform repeated transmission of random access signals to the total number of terminals in a cell is relatively small, the frequency resource required for the second RO resource is relatively small under the premise that the collision probability is approximately the same, thereby improving the utilization efficiency of the second RO resource.

[0087] In one embodiment, X first RO resources and Y second RO resources may be associated according to a uniform mapping principle, and each of the second RO resources may be: TIFF2025511334000002.tif919 or TIFF2025511334000003.tif102 is associated with two first RO resources, or each first RO resource is TIFF2025511334000004.tif921 or TIFF2025511334000005.tif is associated with 1020 second RO resources, where: TIFF2025511334000006.tif97 is the rounding down symbol, TIFF2025511334000007.tif108 is a round-up code. A specific mapping manner may be to divide X first RO resources into Y groups in a packet manner and associate them with Y second RO resources, respectively, or to cycle-map onto Y second RO resources in the order of RO numbers in a cycle mapping manner. As shown in FIG. 6, after determining eight first RO resources RO0-RO7 corresponding to SSBi and two second RO resources RO8 and RO9 corresponding to SSBi, RO0-RO3 are associated with RO8, and RO4-RO7 are associated with RO9 according to the principle of uniform distribution.

[0088] In one embodiment, step S221 includes: Further comprising: determining an association relationship between a first preamble resource set corresponding to a first RO resource in the first RO resource set and a second preamble resource set corresponding to a second RO resource in the second RO resource set; Here, the first preamble resource set includes preamble resources used for repeated transmission of a random access signal on the first RO resource, and the second preamble resource set includes preamble resources used for repeated transmission of a random access signal on the second RO resource.

[0089] The method of determining the association relationship between the first preamble resource set and the second preamble resource set may have various implementation methods, and the embodiment of the present application shows only one embodiment of the invention; According to a second number sequence of the second preamble resource and a first number sequence of the first preamble resource, the second preamble resource is determined by associating the second preamble resource with the first preamble resource in sequence starting from the target second preamble resource; Here, the second number sequence is determined based on the numbers of the second preamble resources in the second preamble resource set, and the first number sequence is determined based on the RO number size of the associated first RO resource and the preamble number size of the first preamble resources in the first preamble resource set.

[0090] The first RO resources are mapped onto the second preamble resources in the second preamble resource set corresponding to the second RO resource in ascending order of RO number and in ascending order of preamble number of the first preamble resources in the corresponding first preamble resource set. As shown in Fig. 6, when the first preamble resource set corresponding to each first RO resource includes n first preamble resources, an association relationship may be established between the first number sequence preamble numbers 0 to 4n-1 obtained by rearranging the first preamble resources in the first preamble resource sets corresponding to RO0 to RO3 and the second preamble resources in the second preamble resource set corresponding to RO8.

[0091] It should be understood that the target secondary preamble resource is the first secondary preamble resource in the secondary preamble resource set, which is the secondary preamble resource numbered 0 by default.

[0092] In one embodiment, the association relationship between the X number of first RO resources and the Y number of second RO resources may be displayed and indicated based on first mapping information carried in the first configuration information. For example, the first mapping information may be first identifier information corresponding to the first RO resource and second identifier information corresponding to the second RO resource, and then, for example, the first RO resource and the second RO resource corresponding to the first identifier information and the second identifier information may be associated based on the first identifier information and the second identifier information.

[0093] In one embodiment, the first mapping information comprises: Association information between the first SSB and the second SSB (e.g., the same SSB, the same SSB subset, a different SSB combination, etc.); An association relationship between the X number of first RO resources and the Y number of second RO resources; and the target second preamble resource.

[0094] In another embodiment, the predefined mapping rule may be associated with a correspondence relationship between the time domain location of the first RO resource and the time domain location of the second RO resource after time domain amplification or extension, that is, determining that the time domain occupied resource of the second RO resource is S times the time domain occupied resource of the first RO resource, and a specific configuration manner may be additionally configuring a slot offset amount or a scaling factor of an RO resource period according to the time domain resource configuration parameter of the first RO resource to obtain an S times second RO resource.

[0095] In one embodiment, the first RO resource and the second RO resource have a 1-to-S association relationship, and the configuration period of the first RO resource includes S times the second RO resource.

[0096] In one embodiment, a first RO resource is associated with S consecutive second RO resources in a time domain of a second RO resource, and the SSBs associated with the S consecutive second RO resources in the time domain coincide with the first RO resource.

[0097] The association pattern from the SSB of the first RO resource to the second RO resource is repeated S times in the second RO resource, and the terminal selects RO resources that are the same as the position of the first RO resource in the association pattern of the second RO resource as the S second RO resources associated with the first RO resource.

[0098] The second preamble set corresponding to the second RO resource and the first preamble set in which the random access signal of the first RO resource is repeatedly transmitted have a one-to-one correspondence and have the same preamble index.

[0099] It should be understood that in the process of associating the second RO resource with the first RO resource, second configuration mapping information may be additionally configured, and the second configuration mapping information may be associated with a time domain, so as to indicate that a time domain RO subset in the first RO resource is associated with the second RO resource.

[0100] It should be understood that the manner of determining the association relationship between RO resources in the first RO resource set may have various implementation manners, and may be determined based on a predefined mapping rule or determined by association identifier information. X RO resources in the first association cycle and X RO resources in the second association cycle are determined, the first association cycle and the second association cycle are association cycles of different times in 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, and the same numbered RO resources establish a mapping relationship based on a predefined mapping rule; or the mapping relationship between the X RO resources in the first association cycle and the X RO resources in the second association cycle is determined based on association identifier information, such as an RO number offset amount, and the same preamble among the X RO resources in the first association cycle and the X RO resources in the second association cycle establish a mapping relationship.

[0101] It should be understood that the manner of determining the association relationship between the RO resources in the first RO resource set may have various implementation manners, and may be determined by a predefined mapping rule or association identifier information. Determine Y RO resources in the third association cycle and Y RO resources in the fourth association cycle, where the third association cycle and the fourth association cycle are association cycles of different times in the second RO resource set, or determine Y RO resources in the first RO time resource and Y RO resources in the second RO time resource, where the first RO time resource and the second RO time resource are RO time resources of different times in the second RO resource set, where 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, and based on a predefined mapping rule, RO resources with the same number establish a mapping relationship; or determine a mapping relationship between the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle based on association identifier information, such as an RO number offset amount, where the Y RO resources in the third association cycle and the Y RO resources in the fourth association cycle have the same preamble and establish a mapping relationship.

[0102] In one embodiment, step S220 includes: The method may further include determining an association relationship between RO resources in the first RO resource set, specifically, First identifier information corresponding to the RO resource; A multiplexing number corresponding to the RO resource; and and an SSB corresponding to the RO resource.

[0103] For example, first RO resources corresponding to the same SSB and having the same multiplexing number may be associated.

[0104] In one embodiment, step S220 includes: The method may further include determining an association relationship between RO resources in the second RO resource set, specifically, Second identifier information corresponding to the RO resource; A multiplexing number corresponding to the RO resource; and and an SSB corresponding to the RO resource.

[0105] For example, a second RO resource corresponding to the same SSB and having the same multiplexing number may be associated.

[0106] In one embodiment, prior to step S230, the method further comprises: The method further includes the step of: when a first condition is satisfied, the terminal determines to perform repeated transmission of a random access signal; Here, the first condition is: The signal quality of the third SSB is lower than a first threshold T0, and the third SSB is an SSB used for repeated transmission of a random access signal; and the number of failures to execute the random access flow reaches a second threshold.

[0107] It should be understood that the third SSB may be an SSB selected by the terminal based on the signal quality of each SSB.

[0108] The terminal can detect a signal quality of a third SSB, such as a downlink path loss reference or RSRP, and when the signal quality of the third SSB is lower than a first threshold T0, the terminal decides to perform repeated transmission of a random access signal. Or, after the terminal performs random access signal transmission and fails M times, the terminal decides to perform repeated transmission of a random access signal, where not receiving an Msg2 message after performing random access signal transmission may be regarded as a random access signal transmission failure.

[0109] In one embodiment, step S230 includes the following steps.

[0110] S231, the terminal determines a number of repetitions based on a signal quality of the third SSB.

[0111] In one embodiment, the terminal may set A-1 first thresholds T1 to obtain A threshold intervals, each corresponding to A types of repetition counts according to the threshold interval in which the SSB signal quality is located. The signal quality of each SSB, for example, RSRP, is compared with the A-1 first thresholds T1 in sequence. An SSB exceeding the first threshold T1 is selected as the third SSB, or an 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 set as the repetition count for repeatedly transmitting the current random access signal. If there are multiple SSBs that satisfy the above condition, one of them may be randomly selected as the third SSB, and if there is no SSB whose signal quality exceeds any first threshold T1, the random access signal is repeatedly transmitted using the maximum repetition count configured by the network. Or, from a number of SSB combinations configured by the network, one SSB combination is selected as the third SSB, and the signal quality of at least one SSB in the SSB combination exceeds the first threshold T1.

[0112] S232, determining N RO resources according to the third SSB, the random access signal repetition number, and an association relationship between the first RO resource set and / or the second RO resource set.

[0113] From the first RO resource set and / or the second RO resource set, determine the first RO resource and / or the second RO resource for performing the repeated transmission of the current random access signal, and the corresponding first preamble resource set and / or the second preamble resource set.

[0114] S233, repeatedly transmitting the random access signal N times through the N RO resources.

[0115] In one embodiment, the repeated transmission of the random access signal may be completed within one or more time units, and the time unit may be an association cycle, an association period, or an association pattern period associated with the 4-step RACH. For example, if one PRACH association period includes a mapping cycles from the SSB to the first RO resource and b mapping cycles from the SSB to the second RO resource, one PRACH association period may support a+b or less repeated transmissions of the random access signal. If the number of repeated transmissions of the random access signal is c, the number of consecutive PRACH association periods occupied by the repeated transmission of the random access signal is c / (a+b). Here, the first association period of the consecutive PRACH association periods is counted from a reference association period defined by a protocol, for example, a PRACH association period starting from radio frame 0, which separates the consecutive PRACH association periods used for the repeated transmission of the random access signal.

[0116] The terminal starts performing repeated transmission of the random access signal with a first RO resource that satisfies a first condition in the time unit as a start RO, where the first condition may be a first RO resource supporting repeated transmission of the random access signal associated with a third SSB in the time unit N times, or a first RO resource or a second RO resource supporting repeated transmission of the random access signal associated with the third SSB in the time unit N times.

[0117] As can be seen, the use of the preamble for the N repeated transmissions of the random access signal is determined by the association relationship between the first RO resource and the second RO resource.

[0118] In one embodiment, the time span for repeatedly transmitting the random access signal should not exceed a preset upper time limit, which may be a PRACH association cycle, a PRACH association period, or a PRACH association pattern period. The system may determine the maximum number of times of repeatedly transmitting the random access signal supported according to the number of first RO resources and second RO resources present in a time range corresponding to the upper time limit.

[0119] After sending the repeated transmission of the random access signal, the terminal needs to monitor and turn on the RAR monitoring window, and monitor the RAR sent from the network side device. The RAR monitoring window turning on manner may have various implementation manners, and the embodiments of the present application will only take some of them as examples to describe the embodiments of the present invention.

[0120] In one embodiment, the terminal may turn on the RAR monitoring window after every random access signal transmission, and the length of the monitoring window may be configured by an RRC message. If the monitoring window does not receive an RAR and the number of times the random access signal is repeatedly transmitted has not reached the repetition count, the terminal retransmits the random access signal on the next determined first RO resource or second RO resource, and if the number of times the transmitted random access signal is repeatedly transmitted reaches the repetition count, the repeated transmission of the random access signal this time may be considered as a failure, and the failure counter of the random access signal transmission is incremented by 1, and an automatic backoff is performed.

[0121] In another embodiment, the terminal may turn on the RAR monitoring window after completing N repeated transmissions of the random access signal, and if the monitoring window does not receive an RAR, it is directly considered that the repeated transmission of the random access signal at this time has failed, and the failure counter of the random access signal transmission is incremented by 1, and an automatic backoff is performed.

[0122] As can be seen from the technical solutions in the above embodiments, in the embodiments of the present application, when a network side device configures a first RO resource set and a second RO resource set for a 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, and further determines an association relationship between the X first RO resources and the Y second RO resources, so as to support repeated transmission of a random access signal with a larger number of repetitions, obtain better diversity gain, and enable the system to efficiently utilize RO resources through the combination of different RO resources.

[0123] Based on the above embodiment, further as shown in FIG. 6, the second RO resource set is located in a single configured BandWidth Part (BWP).

[0124] It should be understood that the independently configured BWP is an uplink BWP (UL BWP), which is only used to configure a second RO resource set, that is, the network side device configures only the second RO resource set in the terminal, and therefore there is no determination of the association relationship between the RO resources in the first RO resource set and the second RO resource set.

[0125] The terminal judges whether to perform repeated transmission of the random access signal by detecting the channel quality of the third SSB, i.e., performs repeated transmission of the random access signal when the channel quality of the third SSB is lower than a first threshold T0. If the terminal performs repeated transmission of the random access signal, the terminal switches onto this independently configured UL BWP, otherwise, it is on a general UL BWP for random access signal transmission.

[0126] The terminal needs to determine an association relationship between the RO resources in the second RO resource set, specifically, Second identifier information corresponding to the RO resource; A multiplexing number corresponding to the RO resource; and and the SSB corresponding to the RO resource.

[0127] In one embodiment, the network side device configures a frequency domain multiplexing number F of RO resources and an association relationship parameter L from an SSB to a second RO resource, where L=k*F. Thus, k consecutive second RO resources in the time domain are associated with the same SSB. The terminal can realize repeated transmission of a random access signal k times or less by using the second RO resources.

[0128] As can be seen from the technical solutions in the above embodiments, the embodiments of the present application configure a second RO resource set located in a BWP configured independently in a terminal to perform repeated transmission of a random access signal by a network side device, thereby supporting repeated transmission of a random access signal with a larger number of repetitions and obtaining a better diversity gain.

[0129] In the random access resource configuration method according to the embodiment of the present application, the execution body can be a random access resource configuration device.

[0137] Additionally, the association module 702 further comprises: Used to determine an association relationship between a first preamble resource set corresponding to a first RO resource in the first RO resource set and a second preamble resource set corresponding to a second RO resource in the second RO resource set; Here, the first preamble resource set includes preamble resources used for repeated transmission of a random access signal on the first RO resource, and the second preamble resource set includes preamble resources used for repeated transmission of a random access signal on the second RO resource.

[0138] Further, each of the second RO resources includes: TIFF2025511334000008.tif919 or TIFF2025511334000009.tif1022 associated with the first RO resource, or each first RO resource is TIFF2025511334000010.tif921 or TIFF2025511334000011.tif is associated with 1020 second RO resources.
