[0019] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0020] It should be noted that, in this disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations, or explanations. Any embodiment or design described in this disclosure using words such as "exemplary" or "for example" should not be interpreted as being more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0021] In the following, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Therefore, a feature defined with the terms "first," "second," etc., may explicitly or implicitly include one or more of such features.

[0022] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" in this document simply describes an association relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exists simultaneously, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0023] When multiple terminals need to access the network, they may select different preamble sequences and transmit Physical Random Access Channel (PRACH) signals containing these preamble sequences, thereby avoiding access conflicts between terminals. However, the preamble sequence set predefined for a particular type of terminal is often fixed. This can lead to wasted preamble resources when there are few access terminals, and insufficient preamble resources when there are many, increasing the probability of conflicts.

[0024] Therefore, it can be seen that the related art preamble sequence allocation method is not flexible enough, which reduces the random access efficiency of the system.

[0025] In response to the above technical issues, the embodiments of the present disclosure provide a transmission resource configuration method, the concept of which is as follows: a first node configures a preamble sequence set for a transmission resource set; the preamble sequence set is used within the transmission resource set; and then the first node sends the configuration information of the transmission resource set and the configuration information of the preamble sequence set to the second node. It can be seen that the method provided by the embodiments of the present disclosure can dynamically allocate preamble sequences for different transmission resources. In this way, the preamble sequence set can be flexibly adjusted to avoid wasting preamble sequence resources and avoiding access conflicts between terminals. Therefore, the random access efficiency of the system can be improved.

[0026] The technical solutions provided by the embodiments of the present disclosure can be applied to various mobile communication networks, for example, NR mobile communication networks using 5G, future mobile communication networks, or multiple communication convergence systems, etc., and the embodiments of the present disclosure are not limited to this.

[0027] In the embodiment of the present disclosure, the network architecture of the mobile communication network (including but not limited to 3G, 4G, 5G and future mobile communication networks) may include at least a first communication node and a second communication node. It should be understood that in this example, in the downlink, the first communication node may be a network side device (for example, including but not limited to a base station), and the second communication node may be a terminal side device (for example, including but not limited to a terminal). Of course, in the uplink, the first communication node may also be a terminal side device, and the second communication node may also be a network side device. In the device-to-device communication between the two communication nodes, the first communication node and the second communication node may both be a base station or a terminal. For ease of description, the first communication node may be described as a first node, and the second communication node may be described as a second node.

[0028] For example, taking the first node as a base station and the second node as a terminal as an example, Figure 1 shows a schematic diagram of a network architecture of a mobile communication network according to an embodiment of the present disclosure. As shown in Figure 1 , the mobile communication network includes a base station 110 and a terminal 120.

[0029] In some embodiments, base station 110 is configured to provide wireless access services to multiple terminals 120. For example, a base station provides a service coverage area (also referred to as a cell). Terminals 120 that enter this area can communicate with base station 110 via wireless signals to receive the wireless access services provided by base station 110.

[0030] In some embodiments, the base station 110 may be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station in a 5G network, or a base station in a future communication system. The base station may include various network-side devices such as various macro base stations, micro base stations, home base stations, wireless remote devices, reconfigurable intelligent surfaces (RIS), routers, and wireless fidelity (WIFI) devices.

[0031] In some embodiments, the terminal 120 can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on the water (such as a ship, etc.); it can also be deployed in the air (for example, on an airplane, a balloon, and a satellite, etc.). The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The embodiments of the present disclosure do not limit the application scenarios. The terminal may sometimes also be referred to as a user, UE (user equipment), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., but the embodiments of the present disclosure are not limited to this.

[0032] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not limited. In addition to the devices shown in Figure 1, the communication system may also include other devices, such as core network devices.

[0033] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0034] The following introduces the transmission resource configuration method provided by the embodiment of the present disclosure.

[0035] The present disclosure provides a transmission resource configuration method, which is applied to the mobile communication network shown in FIG1 (for ease of description, the following description assumes that the first node is a base station and the second node is a terminal). As shown in FIG2 , the transmission resource configuration method includes the following S201 and S202.

[0036] In S201, the base station configures a preamble sequence set for a transmission resource set.

[0037] The preamble sequence set is used within the transmission resource set.

[0038] Exemplarily, the transmission resource set includes M transmission resources, where M is greater than or equal to 1 and is an integer; the preamble sequence set includes P preamble sequences, where P is greater than or equal to 1 and is an integer.

[0039] In some embodiments, the transmission resources include at least one of the following: time domain resources, frequency domain resources, synchronization signal and physical broadcast channel block (Synchronization Signal and Physical Broadcast Channel Block, SSB) resources, and beam resources.

[0040] The time domain resource may include at least one of the following: a time slot, a subframe, a system frame, or an Orthogonal Frequency Division Multiplexing (OFDM) symbol, etc. The time domain resource set includes M time domain resources, where M is greater than or equal to 1 and is an integer.

[0041] Frequency domain resources may include at least one of the following: bandwidth part (BWP), transmission band, physical resource block, subcarrier, subchannel or carrier (including anchor carrier and non-anchor carrier) and other frequency domain resource units.

[0042] The SSB resource is an SSB resource sent by the base station. The SSB resource set includes Q SSB resources, where Q is greater than or equal to 1 and is an integer.

[0043] The beam resource may include at least one of the following: a digital beam, an analog beam, or a precoding matrix, etc. The beam resource set includes Q beam resources, where Q is greater than or equal to 1 and is an integer.

[0044] It is understandable that the configuration information of the transmission resource set may have different forms. Exemplarily, the configuration information of the transmission resource set may have the following five implementation methods.

[0045] In implementation mode 1, the configuration information of the transmission resource set includes at least one of the following: a sequence number of a starting transmission resource, an offset value of a starting transmission resource, a transmission resource interval, and a number of transmission resources.

[0046] The starting transmission resource is the first transmission resource in the transmission resource set. It is understood that the configuration information of the transmission resource set may include the sequence number of the starting transmission resource or the offset value of the starting transmission resource. In this way, the terminal can determine the starting transmission resource based on the sequence number of the starting transmission resource or the offset value of the starting transmission resource.

[0047] The transmission resource interval is the interval between every two adjacent transmission resources in the transmission resource set.

[0048] The number of transmission resources is the number of transmission resources included in the transmission resource set.

[0049] Exemplarily, the configuration information of a transmission resource set may include at least one of the following: the sequence number of the starting transmission resource, the transmission resource interval, and the number of transmission resources. The transmission resource set then includes transmission resource m·T+s, where m is 0, 1, 2, ..., M-1. For example, the transmission resource set includes transmission resource s, transmission resource T+s, transmission resource 2T+s, transmission resource 3T+s, ..., transmission resource (M-1)·T+s, where s is the sequence number of the starting transmission resource, T is the transmission resource interval, and M is the number of transmission resources, where M is greater than or equal to 1 and is an integer, and s is an integer.

[0050] Exemplarily, assuming that the transmission resources include time domain resources, and the configuration information of the time domain resource set includes: a starting time domain resource s, a time domain resource interval T, and a number of time domain resources M, then the time domain resource set includes time domain resource s, time domain resource T+s, time domain resource 2T+s, time domain resource 3T+s, ..., and time domain resource (M-1)·T+s; s is the sequence number of the starting time domain resource, T is the time domain resource interval, and M is the number of time domain resources, where M is greater than or equal to 1. It can be seen that the value of M is indicated by the configuration information of the time domain resource set, or the configuration information of the time domain resource set does not include the number of time domain resources M, the value of M is a predefined integer, and s is an integer.

[0051] Exemplarily, the configuration information of the transmission resource set may include at least one of the following: an offset value f of a starting transmission resource, a transmission resource interval T, and a number of transmission resources M. For example, assuming that the transmission resource is a time domain resource, and the configuration information of the transmission resource set is transmitted on time domain resource n, then the starting time domain resource of the time domain resource set corresponding to the time domain resource offset value f is time domain resource n+f (n and n+f are time domain resource sequence numbers); the time domain resource set includes time domain resources n+f, T+n+f, 2T+n+f, 3T+n+f, ..., (M-1)·T+n+f, where M is greater than or equal to 1 and is an integer, and n and f are both integers.

[0052] Exemplarily, the transmission resources include frequency domain resources, and the configuration information of the frequency domain resource set includes at least one of the following: a sequence number j of a starting frequency domain resource and a number N of frequency domain resources. Furthermore, the frequency domain resource set determined according to the configuration information of the frequency domain resource set includes frequency domain resources j to j+N-1. For example, when j is 0, the frequency domain resource set includes frequency domain resources 0 to N-1. It can be seen that the above-mentioned N value is indicated by the configuration information of the frequency domain resource set, or the configuration information of the frequency domain resource set does not include the number N of frequency domain resources, N is a predefined value greater than or equal to 1 and is an integer, and j is an integer.

[0053] Exemplarily, the transmission resources include frequency domain resources, and the configuration information of the frequency domain resource set includes at least one of the following: the sequence number j of the starting frequency domain resource, the frequency domain resource interval K, and the number of frequency domain resources N. Then, the frequency domain resource set determined according to the configuration information of the frequency domain resource set includes frequency domain resources j, K+j, 2K+j, 3K+j, ..., (N-1)·K+j. It can be seen that the above-mentioned N value is indicated by the configuration information of the frequency domain resource set, or the configuration information of the frequency domain resource set does not include the number of frequency domain resources N, the N value is a predefined value greater than or equal to 1 and is an integer, K is greater than or equal to 1 and is an integer, and j is an integer.

[0054] Exemplarily, the transmission resources include frequency domain resources, and the configuration information of the frequency domain resource set includes at least one of the following: the sequence number j of the starting frequency domain resource, the frequency domain resource interval K, and the number of frequency domain resources N; N and K are greater than or equal to 1 and are integers. The sequence number j of the starting frequency domain resource corresponds to the starting frequency domain position sequence number of the first frequency domain resource in the frequency domain resource set, and j is an integer. The starting frequency domain position sequence number can be the starting subcarrier sequence number, the starting physical resource block sequence number, or the starting subband sequence number. Assuming that the starting frequency domain position in the configuration information of the frequency domain resource set is physical resource block j, the starting positions of all frequency domain resources included in the frequency domain resource set determined according to the configuration information of the frequency domain resource set are j, K+j, 2K+j, 3K+j, ..., (N-1)·K+j respectively. The above-mentioned N value is indicated by the configuration information of the frequency domain resource set, or the configuration information of the frequency domain resource set does not include the number of frequency domain resources N, and the N value is a predefined value.

[0055] Exemplarily, when the transmission resources include SSB resources, the configuration information of the SSB resource set includes at least one of the following: the sequence number i of the starting SSB and the number of SSBs Q. The sequence number i of the starting SSB is the sequence number of the first SSB in the SSB resource set; the number of SSBs Q is the number of SSBs included in the SSB resource set. The SSB resource set determined according to the configuration information of the SSB resource set includes SSB i to SSB i+Q-1; for example, when i is 0, the SSB resource set includes SSB resources 0 to Q-1, and i is an integer. The Q value is indicated by the configuration information of the SSB resource set, or the configuration information of the SSB resource set does not include the number of SSBs Q, and Q is a predefined value greater than or equal to 1 and an integer.

[0056] Exemplarily, when the transmission resources include beam resources, the configuration information of the beam resource set includes at least one of the following: the sequence number i of the starting beam and the number of beams Q. The starting beam corresponds to the first beam in the beam resource set; the number of beams corresponds to the number of beams included in the beam resource set. The beam resource set determined based on the configuration information of the beam resource set includes beam resources i to i+Q-1, where i is an integer. The Q value is indicated by the configuration information of the beam resource set, or the configuration information of the beam resource set does not include the number of beams Q, where Q is a predefined value greater than or equal to 1 and an integer.

[0057] In the second implementation, the configuration information of the transmission resource set includes a configuration information index, where the configuration information index corresponds to at least one of a starting transmission resource sequence number, a transmission resource interval, a transmission resource quantity, and a transmission resource sequence number.

[0058] Exemplarily, the configuration information index may be in the form shown in Table 1 or Table 2 below, where the values ​​in the table are example values.

[0059] Table 1

[0060] Table 2

[0061] In implementation manner three, the configuration information of the transmission resource set includes: a sequence number of at least one transmission resource, and the transmission resources corresponding to the sequence number of the transmission resource constitute the transmission resource set.

[0062] Exemplarily, assuming that the configuration information of the frequency domain resource set includes N frequency domain resource numbers, the frequency domain resource set includes N frequency domain resources corresponding to the N frequency domain resource numbers, where N is greater than or equal to 1 and is an integer.

[0063] In implementation manner four, the configuration information of the transmission resource set includes at least one of the following: a sequence number of the transmission resource, a first value, a second value, and a quantity of the transmission resources.

[0064] In some embodiments, the transmission resource set includes: transmission resource i; or, the transmission resource set includes: transmission resources i to i+C-1; i satisfies mod(i,A)=B; i is the serial number of the transmission resource, A is the first value, B is the second value, C is the number of transmission resources, A and B are both greater than or equal to 1 and are integers, i is an integer, and C is greater than or equal to 1 and is an integer.

[0065] Exemplarily, the transmission resources include time domain resources (e.g., subframes or time slots), and the time domain resource set includes time domain resource i, where i satisfies mod(i, A) = B. Assuming that the first value A is equal to 10 and the second value B is equal to 2, the time domain resource set includes time domain resource i that satisfies mod(i, 10) = 2. For example, the time domain resource set includes time domain resources 2, 12, 22, 32, 42, and so on.

[0066] Exemplarily, the transmission resources include time domain resources (e.g., subframes or time slots), the time domain resource set includes time domain resource i, and the time domain resource set includes time domain resources i to i+C-1, where i satisfies mod(i, A) = B. Assuming that the first value A is equal to 10, the second value B is equal to 2, and the number of time domain resources C is equal to 3, the time domain resource set includes time domain resources i to i+3-1 that satisfy mod(i, 10) = 2. In this way, the time domain resource set includes time domain resources 2, 3, 4, 12, 13, 14, 22, 23, 24, 32, 33, 34, 42, 43, 44, and so on.

[0067] Exemplarily, the transmission resources include frequency domain resources, and the frequency domain resource set includes frequency domain resource i; or, the frequency domain resource set includes frequency domain resource i+C-1; i satisfies mod(i,A)=B.

[0068] Exemplarily, the transmission resources include SSB resources, and the SSB resource set includes SSB resources corresponding to SSB sequence number i; or, the SSB resource set includes SSB resources corresponding to SSB sequence numbers i to i+C-1; i satisfies mod(i,A)=B.

[0069] In implementation manner five, the configuration information of the transmission resource set includes a bitmap for indicating the transmission resources.

[0070] The value of each indicator bit in the bit map is used to indicate whether the transmission resource corresponding to the indicator bit is a transmission resource included in the transmission resource set.

[0071] Exemplarily, the transmission resources include frequency domain resources, and the configuration information of the frequency domain resource set includes a bit map for indicating the frequency domain resources, i.e., a binary bit sequence. In the bit map, each indicator bit corresponds to a frequency domain resource (i.e., a corresponding frequency domain resource sequence number). The value of the indicator bit is used to indicate whether the frequency domain resource corresponding to the indicator bit is a frequency domain resource in the frequency domain resource set.

[0072] In some embodiments, the length of the bitmap (the number of indicator bits included in the bitmap) is determined according to the total number of transmission resources.

[0073] Exemplarily, the transmission resources include frequency domain resources. Assuming that there are a total of 8 frequency domain resources, the length of the bit map is 8, that is, 8 indicator bits, which are used to indicate the 8 frequency domain resources respectively. Assuming that the value of the bit map is 00000011, it indicates that the frequency domain resource set includes the first and second frequency domain resources of the 8 frequency domain resources; assuming that the value of the bit map is 00110010, it indicates that the frequency domain resource set includes the second, fifth, and sixth frequency domain resources of the 8 frequency domain resources.

[0074] Exemplarily, the transmission resource includes an SSB resource, and the configuration information of the SSB resource set includes a bit map for indicating the SSB resource. In the bit map, each indicator bit corresponds to an SSB resource. The value of the indicator bit is used to indicate whether the SSB corresponding to the indicator bit is an SSB resource included in the SSB resource set. For example, an indicator bit with a value of 1 indicates that the SSB corresponding to the indicator bit is an SSB in the SSB resource set.

[0075] It is understandable that the configuration information of the preamble sequence set may have different forms. Exemplarily, the configuration information of the preamble sequence set may have the following four implementations.

[0076] In implementation manner 1, the configuration information of the preamble sequence set includes the sequence number of the preamble sequence set, and the sequence number of the preamble sequence set corresponds to the preamble sequence set.

[0077] For example, assume there are three preamble sequence sets, numbered 0, 1, and 2. The preamble sequence set numbered 0 includes P1 preamble sequences, the preamble sequence set numbered 1 includes P2 preamble sequences, and the preamble sequence set numbered 2 includes P3 preamble sequences, where P1, P2, and P3 are integers greater than or equal to 1. Different preamble sequence sets may contain the same or different number of preamble sequences.

[0078] In the second implementation, the configuration information of the preamble sequence set includes at least one of the following: the sequence number of the starting preamble sequence, the preamble sequence interval, and the number of preamble sequences.

[0079] Illustratively, the preamble sequence set includes a preamble sequence p·H+h, where p is 0, 1, 2, ..., P-1. For example, the preamble sequence set includes preamble sequences h, H+h, 2H+h, 3H+h, ..., (P-1)·H+h. h is the sequence number of the starting preamble sequence and is an integer, H is the preamble sequence interval, and P is the number of preamble sequences and is greater than or equal to 1 and is an integer.

[0080] In implementation manner three, the configuration information of the preamble sequence set includes at least one of the following: a sequence number of the preamble sequence, a third value, a fourth value, and the number of preamble sequences.

[0081] In some embodiments, the preamble sequence set includes a preamble sequence h; or, the preamble sequence set includes preamble sequences h to h+F-1; h satisfies mod(h,D)=E; h is the sequence number of the preamble sequence and is an integer, D is a third value, E is a fourth value, F is the number of preamble sequences, is greater than or equal to 1 and is an integer, and both D and E are greater than or equal to 1 and are integers.

[0082] Exemplarily, assuming that the third value D is equal to 4 and the fourth value E is equal to 0, the preamble sequence set includes the preamble sequence h that satisfies mod(h,4)=0, that is, the preamble sequence set includes preamble sequences 0, 4, 8, 12, ..., P0, where P0 is less than or equal to the total number of preamble sequences and is an integer.

[0083] Exemplarily, assuming that the third value D is equal to 4, the fourth value E is equal to 1, and the number of preamble sequences F is equal to 2, the preamble sequence set includes preamble sequences h to h+2-1 that satisfy mod(h,4)=1, that is, the preamble sequence set includes preamble sequences 1, 2, 5, 6, 9, 10, 13, 14, ..., P0, P0+1, where P0 is less than or equal to the total number of preamble sequences and is an integer.

[0084] In implementation manner 4, the configuration information of the preamble sequence set includes a bit map for indicating the preamble sequence.

[0085] The value of each indicator bit in the bit map is used to indicate whether the preamble sequence corresponding to the indicator bit is a preamble sequence included in the preamble sequence set.

[0086] Exemplarily, the configuration information of the preamble sequence set includes a bit map for indicating the preamble sequence, that is, a binary bit sequence. In the bit map, each indicator bit corresponds to a preamble sequence, and the value of the indicator bit is used to indicate whether the preamble sequence corresponding to the indicator bit is a preamble sequence in the preamble sequence set. For example, a bit map with a length of 16 is used to indicate 16 preamble sequences. Assuming that the value of the bit map is 0000 0000 0000 0011, it means that the preamble sequence set includes the first and second preamble sequences of the 16 preamble sequences; assuming that the value of the bit map is 1000 0000 0011 0010, it means that the preamble sequence set includes the first, fifth, sixth and sixteenth preamble sequences of the 16 preamble sequences.

[0087] In S202, the base station sends configuration information of a transmission resource set and configuration information of a preamble sequence set to the terminal.

[0088] It is understandable that after receiving the configuration information of the transmission resource set and the preamble sequence set sent by the base station, the terminal can determine the preamble sequence set and the transmission resource set based on the configuration information, and send a preamble sequence in the preamble sequence set on a transmission resource within the range of the transmission resource set. In this way, the base station can configure a preamble sequence set for the terminal for each transmission resource set.

[0089] As a possible implementation, S202 may be implemented as follows: the base station sends a first higher-layer configuration parameter, where the first higher-layer configuration parameter is used to indicate configuration information of a transmission resource set; and the base station sends downlink control information, where a first indication field in the downlink control information is used to indicate configuration information of a preamble sequence set. The first higher-layer configuration parameter includes L higher-layer configuration parameters, and the first indication field includes R indication fields, where both L and R are greater than or equal to 1 and are integers.

[0090] Correspondingly, the terminal obtains the configuration information of the transmission resource set by receiving the first higher-layer configuration parameter sent by the base station, and obtains the configuration information of the preamble sequence set by receiving the downlink control information.

[0091] As another implementation, S202 may be implemented as follows: the base station transmits a first high-layer configuration parameter, where the first high-layer configuration parameter is used to indicate configuration information of a preamble sequence set; and the base station transmits downlink control information, where a first indication field in the downlink control information is used to indicate configuration information of a transmission resource set. The first high-layer configuration parameter includes L high-layer configuration parameters, and the first indication field includes R indication fields, where both L and R are greater than or equal to 1 and are integers.

[0092] Correspondingly, the terminal obtains the configuration information of the preamble sequence set by receiving the first higher-layer configuration parameter sent by the base station, and obtains the configuration information of the transmission resource set by receiving the downlink control information.

[0093] As another implementation method, the above S202 can be implemented as: the base station sends a first high-level configuration parameter, which is used to indicate the configuration information of the leading sequence set and / or the configuration information of the transmission resource set; the base station sends downlink control information, which includes activation information, and the activation information is used to indicate whether to activate the leading sequence set and / or the transmission resource set.

[0094] The first high-level configuration parameter includes L high-level configuration parameters, and the first indication field includes R indication fields, where L and R are both greater than or equal to 1 and are integers.

[0095] Accordingly, the terminal obtains configuration information of the preamble sequence set and / or the transmission resource set by receiving the first high-layer configuration parameter, and determines whether to activate the preamble sequence set and / or the transmission resource set by receiving downlink control information.

[0096] Exemplarily, it is assumed that a first higher-layer configuration parameter is used to indicate configuration information of a preamble set and configuration information of a transmission resource set, and that the downlink control information is used to indicate whether to activate the preamble set and the transmission resource set. The configuration information of the preamble set and the configuration information of the transmission resource set are indicated by one or more higher-layer configuration parameters. The configuration information of the preamble set and the configuration information of the transmission resource set are pre-configuration information, and the activation information in the downlink control information is used to indicate whether to activate the pre-configuration information, that is, whether to activate the preamble set and the transmission resource set.

[0097] After sending the configuration information for the preamble set and the transmission resource set, the base station indicates whether to activate the preamble set and the transmission resource set through activation information in the downlink control information. Accordingly, the terminal receives the configuration information for the preamble set and the transmission resource set and determines the corresponding preamble set and transmission resource set. Upon receiving the downlink control information, if the activation information indication field in the downlink control information indicates activation of the preamble set and the transmission resource set, the terminal may use the preamble set within the transmission resource set; if the activation information indication field indicates deactivation of the preamble set and the transmission resource set, then the preamble set and the transmission resource set are not applicable to the terminal until the preamble set and the transmission resource set are activated again.

[0098] For example, assume that a first higher-layer configuration parameter indicates configuration information for a preamble set, and that downlink control information indicates whether to activate the preamble set. The configuration information for the preamble set may be indicated by one or more higher-layer configuration parameters. The configuration information for the preamble set is pre-configuration information, and activation information in the downlink control information indicates whether to activate the pre-configuration information, i.e., whether to activate the preamble set.

[0099] After sending the preamble set configuration information, the base station indicates whether to activate the preamble set through activation information in the downlink control information. Accordingly, the terminal receives the preamble set configuration information and determines the corresponding preamble set. Upon receiving the downlink control information, if the activation information indication field in the downlink control information indicates activation of the preamble set, the terminal may use the preamble set. If the activation information indication field indicates deactivation of the preamble set, the preamble set is not applicable to the terminal until it is reactivated.

[0100] As another implementation method, the above S202 can be implemented as follows: the base station sends a first high-level configuration parameter, which is used to indicate the configuration information of H preamble sequence sets and / or the configuration information of J transmission resource sets; the base station sends downlink control information, and the first indication field in the downlink control information is used to indicate at least one of the following: one preamble sequence set among the H preamble sequence sets, one transmission resource set among the J transmission resource sets; H and J are both greater than or equal to 1 and are integers.

[0101] The first high-level configuration parameter includes L high-level configuration parameters, and the first indication field includes R indication fields, where L and R are both greater than or equal to 1 and are integers.

[0102] Accordingly, the terminal determines the corresponding H preamble sequence sets and J transmission resource sets by receiving the first high-layer configuration parameter, and determines the preamble sequence set applicable to the terminal from the H preamble sequence sets and / or determines the transmission resource set applicable to the terminal from the J transmission resource sets by receiving downlink control information.

[0103] For example, assume that a first higher-layer configuration parameter indicates configuration information for H preamble sets and configuration information for a transmission resource set, and that downlink control information indicates one of the H preamble sets, where H is an integer greater than 1. A terminal receives the configuration information for the H preamble sets and configuration information for the transmission resource set, determines H preamble sets based on the configuration information for the H preamble sets, and determines one transmission resource set based on the configuration information for the transmission resource set. The terminal receives the downlink control information and, based on the first indication field in the downlink control information, determines one of the H preamble sets. The terminal may then use the preamble set within the transmission resource set.

[0104] Exemplarily, assuming that a first high-layer configuration parameter indicates configuration information for a preamble set and configuration information for J transmission resource sets, and a first indication field in the downlink control information indicates one of the J transmission resource sets, where J is an integer and greater than 1. A terminal receives the configuration information for the preamble set and the configuration information for the J transmission resource sets, determines a preamble set based on the configuration information for the preamble set, and determines the J transmission resource sets based on the configuration information for the J transmission resource sets. The terminal receives the downlink control information and determines one of the J transmission resource sets based on the first indication field in the downlink control information. In this manner, the terminal may use the preamble set within the transmission resource set.

[0105] Exemplarily, assume that a first higher-layer configuration parameter indicates configuration information for H preamble sets and configuration information for J transmission resource sets, and that downlink control information indicates one preamble set among the H preamble sets and one transmission resource set among the J transmission resource sets, where H and J are integers greater than 1. A terminal receives the configuration information for the H preamble sets and the configuration information for the J transmission resource sets, and determines the corresponding H preamble sets and J transmission resource sets. The terminal receives the downlink control information and, based on the first indication field in the downlink control information, determines one of the H preamble sets and one of the J transmission resource sets. In this manner, the terminal can use the preamble set within the transmission resource set.

[0106] As another implementation, the above S202 may be implemented as follows: the base station sends downlink control information. The first indication field in the downlink control information is used to indicate configuration information of the preamble sequence set and / or configuration information of the transmission resource set.

[0107] The first indicator field includes R indicator fields, where R is greater than or equal to 1 and is an integer.

[0108] Correspondingly, the terminal obtains the configuration information of the preamble sequence set and / or the configuration information of the transmission resource set by receiving the downlink control information.

[0109] In some embodiments, the configuration information of the transmission resource set and the configuration information of the preamble sequence set may be applied to a terminal in at least one of the following states: idle mode, connected mode, or inactive mode. For example, the base station may instruct a terminal in one of the three states to apply the configuration information of the transmission resource set and the configuration information of the preamble sequence set.

[0110] In some embodiments, the configuration information of the transmission resource set and the configuration information of the preamble sequence set can be applied to at least one of the following scenarios: initial access scenario, scenario in which the second communication node switches from an inactive state to a connected state, radio resource control (RRC) connection reestablishment scenario, cell handover scenario, beam failure recovery scenario, synchronization reconfiguration scenario, timing alignment scenario during secondary cell (Scell) addition, downlink desynchronization-downlink control channel sorting scenario, uplink desynchronization scenario, scenario in which the maximum number of transmissions of the scheduling request (SR) is exceeded, scenario in which uplink data arrives at the SR but the uplink control channel is not configured, and system information request scenario. Exemplarily, the base station instructs the terminal in at least one of the above scenarios to apply the configuration information of the transmission resource set and the configuration information of the preamble sequence set.

[0111] In some embodiments, the first high-level configuration parameter is transmitted in a user equipment-specific (UE-specific) radio resource control (RRC) parameter; or, the first high-level configuration parameter is transmitted in a paging message, a media access control (MAC) layer, or a system information block (SIB).

[0112] In some embodiments, the downlink control information is transmitted in downlink control information scrambled by a paging-Radio Network Temporary Identifier (P-RNTI).

[0124] As another implementation, the configuration information for the transmission resource set includes at least one of the following: a sequence number j of a starting transmission resource and a number N of transmission resources. The transmission resource set determined by the terminal based on the configuration information for the transmission resource set includes transmission resources j through j+N-1. The value of N is indicated by the configuration information for the transmission resource set, or the configuration information for the transmission resource set does not include the number N of transmission resources, where N is a predefined value greater than or equal to 1 and an integer, and j is an integer.

[0125] As another implementation, the transmission resources include frequency domain resources, and the configuration information of the frequency domain resource set includes at least one of the following: the sequence number j of the starting frequency domain resource, the frequency domain resource interval K, and the number of frequency domain resources N, where N and K are greater than or equal to 1 and are integers, and j is an integer.

Assuming that the starting frequency domain position in the configuration information of the frequency domain resource set is physical resource block j, the starting positions of all frequency domain resources included in the frequency domain resource set determined according to the configuration information of the frequency domain resource set are j, K+j, 2K+j, 3K+j, ..., (N-1)·K+j respectively. The above-mentioned N value is indicated by the configuration information of the frequency domain resource set, or the configuration information of the frequency domain resource set does not include the number of frequency domain resources N, and the N value is a predefined value.

[0126] As another implementation, the transmission resources include SSB resources, and the configuration information of the SSB resource set includes at least one of the following: a sequence number i of a starting SSB and a number Q of SSBs. The sequence number i of the starting SSB is the sequence number of the first SSB in the SSB resource set; the number Q of SSBs is the number of SSBs included in the SSB resource set. The SSB resource set determined according to the configuration information of the SSB resource set includes SSB i to SSB i+Q-1.

[0127] As another implementation, the transmission resources include beam resources, and the configuration information of the beam resource set includes at least one of the following: a starting beam index i and a beam number Q. The starting beam corresponds to the first beam in the beam resource set; the beam number Q corresponds to the number of beams included in the beam resource set. The beam resource set is determined to include beam resources i to i+Q-1 based on the configuration information of the beam resource set. The Q value is indicated by the configuration information of the beam resource set, or the configuration information of the beam resource set does not include the beam number Q, where Q is a predefined value greater than or equal to 1 and is an integer, and i is an integer.

[0128] As another implementation, the configuration information of the transmission resource set includes a configuration information index. The configuration information index corresponds to at least one of a starting transmission resource sequence number, a transmission resource interval, a transmission resource quantity, and a transmission resource sequence number. The corresponding transmission resource set is determined based on the configuration information index.

[0129] As another implementation, the configuration information of the transmission resource set includes: a sequence number of at least one transmission resource. According to the transmission resource sequence number included in the configuration information of the transmission resource set, determining the transmission resource set includes: determining the transmission resource corresponding to the at least one transmission resource sequence number.

[0130] As an implementation manner, the configuration information of the preamble sequence set includes the sequence number of the preamble sequence set, and determining the preamble sequence set can be implemented as: determining the preamble sequence set corresponding to the sequence number of the preamble sequence set as the preamble sequence set.

[0131] As another implementation, the configuration information of the preamble sequence set includes at least one of the following: a starting preamble sequence h, a preamble sequence interval H, and the number of preamble sequences. Determining the preamble sequence set can be implemented as follows: determining, based on the starting preamble sequence number h, the preamble sequence interval H, and the number of preamble sequences, that the preamble sequence set includes preamble sequences p·H+h, where p is 0, 1, 2, ..., P-1, P is the number of preamble sequences, is greater than or equal to 1, and is an integer, and h is an integer.

[0132] As another implementation, the configuration information of the preamble sequence set includes at least one of the following: a preamble sequence number h, a third numerical value D, a fourth numerical value E, and a number of preamble sequences F.

[0133] In S303 , the terminal sends a preamble sequence in the preamble sequence set within the transmission resource set.

[0134] Exemplarily, the transmission resources include time domain resources. After receiving the configuration information of the time domain resource set, the terminal may send a preamble sequence in the preamble sequence set on the time domain resources of the time domain resource set.

[0135] Exemplarily, the transmission resources include frequency domain resources. After receiving the configuration information of the frequency domain resource set, the terminal may send a preamble sequence in the preamble sequence set on the frequency domain resources of the frequency domain resource set.

[0136] Exemplarily, the transmission resource includes an SSB resource. The terminal determines an SSB, and after receiving configuration information of an SSB resource set, if the SSB determined by the terminal belongs to the SSB resource set corresponding to the configuration information of the SSB resource set, a preamble sequence in the preamble sequence set may be sent.

[0137] Exemplarily, the transmission resources include beam resources. After receiving configuration information for a beam resource set, the terminal may use a preamble sequence set while using a beam in the beam resource set. For example, when the terminal transmits a preamble sequence using a beam in the beam resource set, the preamble sequence transmitted by the terminal is a preamble sequence in the preamble sequence set.

[0138] It is understood that when the transmission resources include multiple different types of transmission resources, the terminal must meet the requirements of each of the multiple different types of transmission resources in order to send a preamble sequence from the preamble sequence set. For example, when the transmission resources include time-domain transmission resources and frequency-domain transmission resources, after receiving the configuration information for the time-domain resource set and the configuration information for the frequency-domain resource set, the terminal determines whether the time-domain resource and the frequency-domain resource for sending the preamble sequence belong to the time-domain resource set and the frequency-domain resource set, respectively. If so, the terminal sends a preamble sequence from the preamble sequence set.

[0139] It should be noted that the transmission resource configuration method provided in the embodiments of the present disclosure, as well as the transmission resource configuration information and the preamble sequence set configuration information involved in the transmission resource configuration method can be applied to at least one of the following scenarios: initial access scenario, terminal transition from inactive state to connected state scenario, RRC connection reestablishment scenario, cell handover scenario, beam failure recovery scenario, synchronization reconfiguration scenario, timing alignment scenario during secondary cell (Scell) addition, downlink desynchronization-downlink control channel sorting scenario, uplink desynchronization scenario, exceeding the maximum number of scheduling request (SR) transmission times scenario, uplink data arriving at SR without configuring uplink control channel scenario, system information request scenario. Exemplarily, the base station can instruct a terminal in one of the above scenarios to apply the transmission resource set configuration information and the preamble sequence set configuration information.

[0140] In summary, based on the transmission resource configuration method provided by the embodiments of the present disclosure, the first node can configure a preamble sequence set for a transmission resource set; the preamble sequence set is used within the transmission resource set; and then the first node sends the configuration information of the transmission resource set and the configuration information of the preamble sequence set to the second node. It can be seen that the method provided by the embodiments of the present disclosure can dynamically allocate preamble sequences for different transmission resources. In this way, the preamble sequence set can be flexibly adjusted to avoid wasting preamble sequence resources and avoiding access conflicts between terminals, thereby improving the random access efficiency of the system.
