DETAILED DESCRIPTION

The technical solutions in the present disclosure will be described clearly and completely below in conjunction with the drawings in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to describe examples, illustrations or explanations. Any embodiment or design described in the present disclosure by words such as "exemplary" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined by the terms "first", "second", etc. may explicitly or implicitly include one or more of the features.

In the description of the present disclosure, unless otherwise specified, "/" means "or", for example, A/B can mean A or B. "And/or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

When multiple terminals need to access the network, different terminals may select different preamble sequences and send a Physical Random Access Channel (PRACH) signal containing the preamble sequence, thereby avoiding access conflicts between terminals. However, for a type of terminal, the predefined preamble sequence set is often a fixed set. Then, when there are fewer access terminals, it will cause a waste of preamble sequence resources; when there are more access terminals, it may lead to insufficient preamble sequence resources, thereby increasing the probability of conflict.

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

In response to the above technical problems, the embodiment of the present disclosure provides a transmission resource configuration method, the idea of which is that: the 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 embodiment of the present disclosure can dynamically allocate preamble sequences for different transmission resources, so that the preamble sequence set can be flexibly adjusted to avoid waste of preamble sequence resources and avoid access conflicts between terminals, thereby improving the random access efficiency of the system.

The technical solution 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.

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.

The following is an introduction to the transmission resource configuration method provided by an embodiment of the present disclosure.

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 is given with the first node being a base station and the second node being a terminal). As shown in FIG2 , the transmission resource configuration method includes the following S201 and S202.

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

The preamble sequence set is used within the transmission resource set.

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.

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.

The time domain resources may include at least one of the following: time domain resources such as time slots, subframes, system frames, or Orthogonal Frequency Division Multiplexing (OFDM) symbols. The time domain resource set includes M time domain resources, where M is greater than or equal to 1 and is an integer.

The frequency domain resources may include at least one of the following: frequency domain resource units such as bandwidth part (Bandwidth Part, BWP), transmission band, physical resource block, subcarrier, subchannel or carrier (including anchor carrier and non-anchor carrier).

The SSB resource is the 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.

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.

It can be understood that the configuration information of the transmission resource set can have different forms. Exemplarily, the configuration information of the transmission resource set can have the following five implementation methods.

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.

The starting transmission resource is the first transmission resource in the transmission resource set. It is understandable 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 may determine the starting transmission resource based on the sequence number of the starting transmission resource, or determine the starting transmission resource by the offset value of the starting transmission resource.

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

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

Exemplarily, the configuration information of the 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, then the transmission resource set includes transmission resource m·T+s, where the value of 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; s is the sequence number of the starting transmission resource, T is the transmission resource interval, M is the number of transmission resources, M is greater than or equal to 1 and is an integer, and s is an integer.

Exemplarily, assuming that the transmission resource includes a time domain resource, 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 time domain resource quantity M, then the time domain resource set includes a time domain resource s, a time domain resource T+s, a time domain resource 2T+s, a time domain resource 3T+s, ..., a 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, M is the time domain resource quantity, and M is greater than or equal to 1. It can be seen that the above M value 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 time domain resource quantity M, the M value is a predefined value and is an integer, and s is an integer.

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 transmission resource quantity 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 a 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 a time domain resource n+f (n, 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, M is greater than or equal to 1 and is an integer, and n and f are both integers.

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 and the number of frequency domain resources N. Further, 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 of frequency domain resources N, N is a predefined value, greater than or equal to 1 and is an integer, and j is an integer.

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.

Exemplarily, the transmission resource includes 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 frequency domain The starting frequency domain position number of the first frequency domain resource in the resource set, j is an integer. The starting frequency domain position number can be a starting subcarrier number, a starting physical resource block number, or a starting subband number, etc. 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.

Exemplarily, in the case where the transmission resource includes an SSB resource, 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 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, in the case where 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.

Exemplarily, in the case where the transmission resources include beam resources, the configuration information of the beam resource set includes at least one of the following: the serial 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 according to 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 is an integer.

In implementation mode 2, the configuration information of the transmission resource set includes a configuration information index, and 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.

Exemplarily, the configuration information index may be in the form shown in the following Table 1 or Table 2, where the values in the table are example values.

Table 1

Table 2

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

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.

In implementation method 4, 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.

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 sequence 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.

Exemplarily, the transmission resource includes a time domain resource (e.g., a subframe or a time slot), and the time domain resource set includes a 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 a 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, etc.

Exemplarily, the transmission resources include time domain resources (e.g., subframes or time slots), the time domain resource set includes time domain resource i, the time domain resource set includes time domain resources i to i+C-1, and 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, so that 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.

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.

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.

In implementation mode 5, the configuration information of the transmission resource set includes a bitmap for indicating the transmission resources.

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.

Exemplarily, the transmission resource includes a frequency domain resource, and the configuration information of the frequency domain resource set includes a bit map for indicating the frequency domain resource, that is, a binary bit sequence. In the bit map, each indicator bit (bit) corresponds to a frequency domain resource (that is, 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.

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.

Exemplarily, the transmission resources include frequency domain resources. Assuming that there are 8 frequency domain resources in total, 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 means 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 means that the frequency domain resource set includes the second, fifth and sixth frequency domain resources of the 8 frequency domain resources.

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.

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.

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.

For example, it is assumed that there are three preamble sequence sets, which are 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 greater than or equal to 1 and are integers. The number of preamble sequences included in different preamble sequence sets may be the same or different.

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.

Exemplarily, the preamble sequence set includes a preamble sequence p·H+h; the value of 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, which is greater than or equal to 1 and is an integer.

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 a number of preamble sequences.

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.

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.

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

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

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.

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.

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

It can be understood that after receiving the configuration information of the transmission resource set and the configuration information of the preamble sequence set sent by the base station, the terminal can determine the preamble sequence set and the transmission resource set according to 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. Thus, the base station can configure a preamble sequence set for the terminal for a transmission resource set.

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

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

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

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

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

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

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

Exemplarily, it is assumed that the first high-level configuration parameter is used to indicate the configuration information of the preamble sequence set and the configuration information of the transmission resource set, and the downlink control information is used to indicate whether to activate the preamble sequence set and the transmission resource set.
