Description

Communication method and communication device

Technical Field

The present application relates to the field of communications, and more particularly, to a transmission communication method and apparatus.

Background

In a communication system, control information is typically used to allocate Resource Blocks (RBs) for transmission of data channels to communication devices (e.g., terminal devices). In a scenario where the terminal device communicates with the network device, the control information may be Downlink Control Information (DCI). After receiving the control information, the communication device may determine, according to the control information, parameters such as an RB occupied by the transmission data channel and the number of repetitions of the transmission data channel. The RB occupied by the transmission data channel may be determined by a starting RB and an RB length, and the number of repetitions may be selected from 4 kinds of repetitions specified in a communication protocol.

Currently, when determining the three parameters (i.e. the number of resource blocks, the starting resource block, and the number of repetitions) for a communication device, no matter how good the channel quality is, each number of resource blocks needs to be combined with each of the 4 kinds of repetitions to obtain all combinations, so that other communication devices can determine one combination for the communication device from all the combinations to instruct the communication device to transmit data. However, the above-mentioned methods for obtaining all combinations are not reasonable.

Disclosure of Invention

The application provides a communication method and communication equipment, which aim to improve the rationality of a combination mode between the number of repetition times and the number of resource blocks.

In a first aspect, a communication method is provided, including: a first communication device receives control information, wherein the control information indicates the number L of resource blocks distributed to the first communication device and the number N of repetition times; and the first communication equipment sends a data channel to second communication equipment according to the number L of the resource blocks and the number N of the repetition times, wherein the number L of the resource blocks belongs to a first resource block number set in a plurality of resource block number sets, each resource block number set in the plurality of resource block number sets is associated with one repetition time set, the number N of the repetition times belongs to a first repetition time set, and the first repetition time set is the repetition time set associated with the first resource block number set.

In the embodiment of the present application, a set of repetition times is associated with each set of resource block numbers, and thus the number of repetitions allocated to the first communications device is determined from the first set of repetition times associated with the number L of resource blocks. That is to say, the number L of resource blocks only needs to be combined with the number of repetitions included in the first set of repetitions, which avoids that the sets of repetitions associated with all the numbers of resource blocks in the prior art are the same, and is beneficial to improving the rationality of the combination mode between the number of resource blocks and the number of repetitions.

In one possible implementation, the method further includes: the first communication equipment determines a starting resource block allocated to the first communication equipment according to the control information; the first communication device sends a data channel to a second communication device according to the number L of the resource blocks and the number N of the repetition times, and the method comprises the following steps: and the first communication equipment sends a data channel to the second communication equipment according to the number L of the resource blocks, the repetition times N and the initial resource block.

Optionally, the sets of repetition times associated with different sets of numbers of resource blocks in the plurality of sets of numbers of resource blocks are different.

Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Fig. 1 is a wireless communication system 100 to which an embodiment of the present application is applied. The wireless communication system 100 may include a network device 110. Network device 110 may be a device that communicates with terminal device 120. Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area.

Fig. 1 exemplarily shows one network device and two terminals, and optionally, the wireless communication system 100 may include a plurality of network devices and may include other numbers of terminals within the coverage of each network device, which is not limited in this embodiment of the present application.

Optionally, the wireless communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in this embodiment.

It should be understood that the technical solution of the present application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an Advanced Long Term Evolution (LTE-a) System, a Universal Mobile Telecommunications System (UMTS), a New Radio Access Technology (NR), 5G, and the like.

It should also be understood that, in the embodiment of the present application, the terminal device may include, but is not limited to, a terminal device applied in the internet of things, for example, a terminal device accessing NB-IoT (may be referred to as "NB-IoT terminal"): intelligent meter reading equipment, logistics tracking equipment, environment monitoring equipment and the like; the Terminal may further include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), and the like, where the Terminal may communicate with one or more core networks via a Radio Access Network (RAN), for example, the Terminal may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal may also be a portable, pocket, hand-held, computer-built-in, or vehicle-mounted Mobile device.

In this embodiment of the present application, the network device may be an access network device, for example, a Base Station, a Transmit and Receive Point (TRP) or an access Point, where the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, or a Base Station (gNB) in NR or 5G, which is not specifically limited in this embodiment of the present application.

A conventional resource allocation method is described below based on the communication system shown in fig. 1. The network equipment sends downlink control information to the terminal equipment, and the resource block allocated to the terminal equipment and the repetition times are indicated through the downlink control information, so that the terminal equipment is guided to transmit a data channel on the resource block according to the repetition times. The resource blocks allocated to the terminal device are indicated by a starting resource block and the number of resource blocks (also referred to as "resource block length").

Currently, a plurality of initial resource blocks, a plurality of resource block numbers, and a plurality of repetition times are specified in a communication protocol. When determining the number of resource blocks, and the number of repetitions for the terminal device, the network device may select a suitable combination for the terminal device from a plurality of combinations obtained from the plurality of starting resource blocks, the plurality of resource blocks, and the plurality of repetitions.

The plurality of combinations include a combination of each number of resource blocks and each of the plurality of kinds (for example, 4 kinds) of repetition times. However, the combination of the number of the resource blocks and the number of the repetitions is not reasonable, so that the number of combinations to be identified between the network device and the terminal device is increased, which results in an increase in the overhead of downlink control information. For example, if the channel quality is poor, in order to improve the reliability of data transmission, the network device generally allocates a shorter number of resource blocks to the terminal device, so that the total transmission power of the terminal device can be concentrated on the allocated resource blocks. Accordingly, the network device may also prefer a larger number of repetitions when selecting the number of repetitions. For another example, if the channel quality is good, the reliability of data transmission can be guaranteed to a certain extent by the channel quality, and the network device allocates a longer number of resource blocks to the terminal device, so as to improve the efficiency of data transmission by the terminal device. The network device may also typically select a smaller number of repetitions due to the better channel quality. In summary, the number of repetitions allocated to the terminal device is related to the channel quality, and the number of resource blocks allocated to the terminal device is also related to the channel quality. Based on the rule, the embodiment of the application provides a new resource allocation mechanism to improve the rationality of the combination mode between the number of the resource blocks and the repetition times.

The following describes a communication method according to an embodiment of the present application with reference to fig. 2. Fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present application. The method shown in fig. 2 includes steps 210 to 220. It should be noted that the method of the embodiment of the present application may be applied to a scenario in which the network device and the terminal device in fig. 1 communicate, where the first communication device may be the terminal device, and the second communication device may be the network device. The solution of the embodiment of the present application may also be applied to a scenario of device to device (D2D) communication, and the first communication device and the second communication device in the following may be two terminal devices that communicate with each other.

The first communication device receives control information indicating the number L of resource blocks allocated to the first communication device and the number N of repetitions 210. The number L of the resource blocks belongs to a first resource block number set in the plurality of resource block number sets, each resource block number set in the plurality of resource block number sets is associated with a repetition number set, the repetition number N belongs to a first repetition number set, and the first repetition number set is the repetition number set associated with the first resource block number set.

The number L of resource blocks is used to indicate the number of resource blocks allocated to the first communication device, or the number of resource blocks occupied by the first communication device for transmitting the data channel, and may be, for example, the length of the resource blocks mentioned above. The plurality of resource blocks may be continuous or discontinuous, which is determined according to the number L of resource blocks.

The repetition number N may indicate the repetition number of transmitting the control information, or the repetition number of transmitting the data channel, or both.

Each resource block number set in the plurality of resource block number sets is associated with one repetition number set, and may include different resource block number sets associated with different repetition number sets. Or at least two of the plurality of resource block number sets may be associated with different sets of repetition times, while the remaining resource block number sets of the plurality of resource block number sets may be associated with the same set of repetition times.

It should be understood that the first set of resource block numbers may include one or more resource block numbers, and the first set of repetition times may include one or more repetition times.

It should also be understood that the names of the control information in the embodiments of the present application are not limited, and may refer to information having the same function in the current communication protocol as well as in the future communication protocol. For example, Downlink Control Information (DCI) in the existing communication protocol.

The "number of resource blocks L" may be the number of allocated resource blocks or the length of allocated resource blocks. The number value of the resource block number is not limited, wherein L is a symbol only and is only used for distinguishing from other resource block numbers, and does not represent a value. The number L of resource blocks may be replaced by a "resource block length" or a "first number of resource blocks". The repetition number N may refer to a certain repetition number, but the value of the repetition number is not limited, where N is only used to distinguish from the number of other resource blocks, and does not represent a value. The above-mentioned "number of repetitions N" may be replaced with "first number of repetitions".

It should be noted that the number L of resource blocks and the number N of repetitions may be carried in the same field in the control information, and the number L of resource blocks and the number N of repetitions may also be carried in different fields in the control information, which is not limited in this embodiment of the present application.

Optionally, the first communication device is a coverage level 0, or a coverage level 1, or a terminal device of a coverage enhancement level a.

220, the first communication device sends a data channel to the second communication device according to the number L of resource blocks and the repetition number N.

If the repetition number N is the repetition number of transmitting the DCI, the first communication device sends the data channel to the second communication device according to the repetition number N, which may be understood as that the first communication device (i.e., the terminal device) may determine the timing of transmitting the data channel according to the repetition number of transmitting the DCI.

Based on the above description, if the channel quality is better, the number of resource blocks allocated to the first communication device is larger. The corresponding situation is more when the number of the resource blocks allocated to the first communication device is less, except for the case that the channel quality is poor, the number of the resource blocks allocated to the first communication device is less, and another situation may exist, that is, the data volume of the data to be transmitted by the first communication device is originally less, and more resource blocks are not needed.

It can be seen that, in establishing the association between the resource block number set and the repetition number set, if the number of resource blocks in the resource block number set is large, the applicable situation is relatively simple, that is, the channel quality is good, and therefore, the number of repetition times included in the associated repetition number set may be small, that is, the number of selectable repetition times in the associated repetition number set is small. If the number of resource blocks in the resource block number set is small, the applicable conditions are complex, including various conditions that the channel quality is poor and the data amount of data to be transmitted is small, so that the number of the repetition times contained in the associated repetition time set can be large, that is, the number of the selectable repetition times in the associated repetition time set is large, and thus, a large combination mode can be obtained according to the resource block number set and the repetition time set to adapt to the various conditions.

That is, the plurality of resource block number sets further includes a second resource block number set, and the second resource block number set is associated with a second repetition number set, a minimum number of resource blocks in the second resource block number set is greater than a maximum number of resource blocks in the first resource block number set, and a number of repetition times in the second repetition number set is not more than (i.e., is less than or equal to) a number of repetition times in the first repetition number set. Optionally, the second set of repetition times is a subset of the first set of repetition times. Of course, there may be no subset relationship between the first set of repetition times and the second set of repetition times.

For example, the plurality of resource block number sets include a first resource block number set and a second resource block number set, where the number of resource blocks in the first resource block number set is 1, and the number of resource blocks in the second resource block number set is 2, and then the first repetition number set associated with the first resource block number set is { n }₁,n ₂,n ₃,n ₄And the second repeated times associated with the second resource block number set are set as { n }₁,n ₄Wherein n, which represents the value of the repetition number₁,n ₂,n ₃,n ₄Is a positive integer.

Or, the minimum number of resource blocks in the first set of resource block numbers is greater than the maximum number of resource blocks in the second set of resource block numbers, and the number of repetition times in the first set of repetition times is not more than (i.e., is less than or equal to) the number of repetition times in the second set of repetition times. Optionally, the first set of repetition times is a second set of repetition times. Of course, there may be no subset relationship between the first set of repetition times and the second set of repetition times.

The embodiment of the application provides a correlation mode of four resource block number sets and a repetition number set, so as to control the number of the resource block number and the number of the repetition number combinations, thereby controlling the bit positions occupied by the resource block number and the repetition number indicated in the control information.

The first association method comprises the following steps: the plurality of resource block number sets include a third resource block number set { c, d }, the first resource block number set is { a }, the second resource block number set is { b }, the first repetition number set includes 4 repetition times, the second repetition number set includes 2 repetition times, the third repetition number set associated with the third resource block number set includes 1 repetition time, wherein a, b, c, d representing different resource block numbers are positive integers, and a < b < c < d.

And in a second association mode, the first resource block number set is { a, b }, the second resource block number set is { c, d }, the repetition number set associated with the first resource block number set comprises 3 repetition numbers, the second repetition number set comprises 2 repetition numbers, a, b, c and d which represent different resource block numbers are positive integers, and a < b < c < d.

In a third association manner, the first resource block number set is { a }, the second resource block number set is { b, c, d }, the first repetition number set includes 4 repetition numbers, the second repetition number set includes 2 repetition numbers, a, b, c, d representing different resource block numbers are positive integers, and a < b < c < d.

And in a fourth association mode, the first resource block number set is { e }, the second resource block number set is { f }, the first repetition number set comprises 8 repetition numbers, and the second repetition number set comprises 4 repetition numbers, wherein e and f which represent different resource block numbers are positive integers, and e < f.

It should be noted that, in the embodiment of the present application, specific values of the number of repetitions in the association manners one to four are not limited, and the number of repetitions specified in the current communication protocol and the number of repetitions specified in the future communication protocol may be compatible.

The control information may indicate, in addition to the number L of resource blocks allocated to the first communication device and the number N of repetitions, a starting resource block allocated to the first communication device, so that the first communication device determines, according to the starting resource block and the number of resource blocks, a resource block occupied by a transmission data channel.

Namely, the method further comprises: the first communication equipment determines a starting resource block allocated to the first communication equipment according to the control information; step 220 includes the first communications device sending a data channel to a second communications device according to the number L of resource blocks, the number N of repetitions, and the starting resource block.

The starting resource block may be predefined in the communication protocol, or may be indicated to the first communication device by the second communication device through signaling. The signaling may be any one of physical layer signaling, medium access layer signaling, or radio resource control signaling.

The embodiment of the application provides a plurality of association modes of the number of the resource blocks and the initial resource block, so as to control the number of the resource blocks and the number of the candidate initial resource block combinations, thereby indicating the number L of the resource blocks and the bit positions occupied by the initial resource blocks in the control information. Wherein the starting resource block allocated for the first communication device is determined from the candidate starting resource blocks.

Alternatively, multiple resource block number sets may be associated with the same candidate starting resource block, i.e., one or more candidate starting resource blocks with which each resource block number set may be associated are the same. Of course, the plurality of resource block number sets may also be associated with a plurality of candidate starting resource block sets, where a candidate starting resource block set includes one or more candidate starting resource blocks. And the candidate starting resource block sets related to at least two resource block number sets in the plurality of resource block number sets are different. The following describes the association manner between the resource block number set and the candidate starting resource block in combination with the association manner five to the association manner eight.

And a fifth association method, if the first resource block number set is { a }, the second resource block number set is { b }, and the third resource block number set is { c, d }, the association method of the resource block number and the starting resource block can be subdivided into the following three association methods five (1) to five (2).

And a correlation mode five (1), wherein each resource block number in the first resource block number set is correlated with 2 candidate starting resource blocks, each resource block number in the second resource block number set is correlated with 3 candidate starting resource blocks, and each resource block number in the third resource block number set is correlated with 1 candidate starting resource block.

And a correlation mode five (2), wherein each resource block number in the first resource block number set is correlated with 3 candidate starting resource blocks, each resource block number in the second resource block number set is correlated with 1 candidate starting resource block, and each resource block number in the third resource block number set is correlated with 1 candidate starting resource block.

And a sixth association mode, where the first resource block number set is { a, b }, the second resource block number set is { c, d }, each resource block number in the first resource block number set is associated with 2 candidate starting resource blocks, and each resource block number in the second resource block number set is associated with 1 candidate starting resource block.

And a seventh association mode, where the first resource block number set is { a }, the second resource block number set is { b, c, d }, a resource block number a in the first resource block number set is associated with 2 candidate starting resource blocks, a resource block number b in the second resource block number set is associated with 2 candidate starting resource blocks, a resource block number c in the second resource block number set is associated with 1 candidate starting resource block, and a resource block number d in the second resource block number set is associated with 1 candidate starting resource block.

And in an association mode eight, the first resource block number set is { a }, the second resource block number set is { b }, the resource block number a in the first resource block number set is associated with 3 candidate starting resource blocks, and the resource block number b in the first resource block number set is associated with 2 candidate starting resource blocks.

Optionally, in an association manner eight, the first communication device may be a coverage level 2, or a coverage level 3, or a terminal device of a coverage enhancement level B.

It should be noted that the starting resource block may be indicated by an identifier (e.g., an index number) of the resource block.

Alternatively, a-1, b-2; or, a is 1, b is 2, c is 4, and d is 6; or a is 1, b is 2, c is 3 and d is 4.

The association relationship between the resource block number set indicated by the association manner one to the association manner four and the repetition number and the association relationship between the resource block number set indicated by the association manner five to the association manner six and the starting resource block can be used in combination. For example, the association mode one may be used in combination with the association mode five, the association mode two may be used in combination with the association mode six, and the association mode three may be used in combination with the association mode seven.

3 specific implementations are listed below in conjunction with tables 1-3. It should be noted that the specific values shown in tables 1 to 3 are only for helping understanding the scheme of the embodiment of the present application, and do not limit the embodiment of the present application.

The specific implementation shown in tables 1 to 3 is described by taking the allocation of resources in a narrowband or a partial Bandwidth (BWP) as an example, and it is assumed that one narrowband or BWP includes 6 resource blocks, and the indexes of the resource blocks are 0, 1, 2, 3, 4, and 5 in sequence.

TABLE 1

In table 1, the first resource block number set is {1}, the second resource block number set is {2}, and the second resource block number set is {4, 6 }. The number of indexes of candidate initial resource blocks corresponding to the first resource block number set is 2, and the first resource block number set is associated with the first repetition number set; the number of indexes of the candidate initial resource blocks corresponding to the second resource block number set is 3, and the second resource block number set is associated with a second repetition number set; the number of the indexes of the candidate initial resource blocks corresponding to the third resource block number set is 1, and the third resource block number set is associated with the third repetition number set.

Wherein there are 4 kinds of repetition times in the first repetition time set, i.e. { n }₁,n ₂,n ₃,n ₄}. The second repeat number set has 2 repeat numbers which can be n₁,n ₂,n ₃,n ₄Two kinds of (1). For example, the second repetitionThe number set is { n₂,n ₄}. Or, the second set of repetition times is { n }₁,n ₃}. Or, the second set of repetition times is { n }₃,n ₄}. The third repetition number set has 1 repetition number which can be n₁,n ₂,n ₃,n ₄1 kind of (1). For example, the third repeated number set is { n }₁}. Alternatively, the third repeated number set is { n }₂In which n is₁,n ₂,n ₃,n ₄Is a positive integer. Alternatively, n₁<n ₂<n ₃<n ₄。

Based on table 1, the number of resource blocks, candidate starting resources, and the number of repetitions are 16 in total, that is, 2 × 4+3 × 2+1 × 1+1 × 1 — 16 — 2⁴. In this way, the 16 combinations can be represented by 4 bits (bits) in the control information.

Optionally, the indexes of the 2 candidate starting resource blocks corresponding to the first resource block number set may be two of the indexes of the 6 resource blocks. For example {0, 3} or {0, 1} or {0, 2} or {4, 5} or {0, 4 }. The index of the 3 candidate starting resource blocks corresponding to the second resource block number set may be 3 of the 6 resource blocks. For example {0, 2, 4} or {0, 1, 4} or {1, 3, 5 }. The index of the 1 candidate starting resource block corresponding to the third resource block number set may be fixed to 1 of the 6 resource blocks, for example, to {0 }.

When the number of resource blocks occupied by the first communication device is small, in order to improve the utilization rate of resources, resources may be allocated to other communication devices on the remaining idle resource blocks, that is, a plurality of communication devices share a resource block in one narrow band. The configuration of the candidate starting resource blocks corresponding to different numbers of the resource blocks is beneficial to avoiding resource collision when resources are allocated to a plurality of communication devices in one narrow band.

For example, the number of resource blocks allocated to the communication device 1 is 2, which belongs to the second set of resource block numbers, and the index of the candidate starting resource block associated with the second set of resource block numbers is 0, 2, 4. If the number of resource blocks allocated to the communication device 1 is 4, the resource blocks belong to the third set of resource block numbers, and the index of the candidate starting resource block associated with the third set of resource block numbers is 0, then, in order to avoid collision, the index of the candidate starting resource block preferentially selected from the indexes 0, 2, and 4 of the candidate starting resource block associated with the second set of resource block numbers is 4. In this way, the indexes of the resource blocks occupied by the communication device 1 are 4 and 5, and the indexes of the resource blocks occupied by the communication device 2 are 0, 1, 2 and 3.

In summary, to avoid collision, indexes of corresponding candidate resource blocks may be associated for different resource block number sets. For example, the indexes of the candidate starting resource blocks associated with the first set of resource block numbers may be 0, 4, the indexes of the candidate starting resource blocks associated with the second set of resource block numbers may be 0, 2, 4, and the indexes of the candidate starting resource blocks associated with the second set of resource block numbers may be 0.

TABLE 2

In table 2, the first number set of resource blocks is {1} and the second number set of resource blocks is {2, 4, 6 }. The number of indexes of candidate initial resource blocks corresponding to the first resource block number set is 2, and the first resource block number set is associated with the first repetition number set; the number of the indexes of the candidate initial resource blocks corresponding to the second resource block number set is 2, and the second resource block number set is associated with the second repetition number set.

Wherein the first set of repetition times { n }₁,n ₂,n ₃,n ₄There were 4 replicates. The second repetition number set comprises 2 repetition numbers which can be n₁,n ₂,n ₃,n ₄Two kinds of (1). For example, the second set of repetition times is { n }₂,n ₄}. Or,the second set of repetition times is { n }₁,n ₃}. Or, the second set of repetition times is { n }₃,n ₄}. The third repeat number set has 1 repeat number, which may be n₁,n ₂,n ₃,n ₄1 kind of (1). For example, the third repeated number set is { n }₁}. Alternatively, the third repeated number set is { n }₂In which n is₁,n ₂,n ₃,n ₄Is a positive integer. Alternatively, n₁<n ₂<n ₃<n ₄。

Based on table 2, the number of resource blocks, candidate starting resources, and the number of repetitions are 16 in total, that is, 2 × 4+2 × 2+1 × 2+1 × 2 is 16 or 2⁴. In this way, the 16 combinations can be represented by 4 bits (bits) in the control information.

Optionally, the indexes of the 2 candidate starting resource blocks corresponding to the first resource block number set may be two of the indexes of the 6 resource blocks. For example {0, 3} or {0, 1} or {0, 2} or {4, 5} or {0, 4 }. The index of the 2 candidate starting resource blocks corresponding to the second resource block number set may be 2 of the 6 resource blocks. For example {0, 2} or {2, 4} or {0, 4} or {1, 4 }. The index of 1 candidate starting resource block corresponding to the third resource block number set may be 1 of the 6 resource blocks. For example, {0 }.

In order to avoid collision while improving the utilization rate of resources, indexes of corresponding candidate resource blocks can be associated with different resource block number sets. For example, the indexes of the candidate starting resource blocks associated with the first resource block number set may be 0 and 4, the index of the candidate starting resource block associated with the resource block number 2 in the second resource block number set may be 1 and 4, and the indexes of the candidate starting resource blocks associated with the resource block numbers 4 and 6 in the second resource block number set may be 0.

TABLE 3

In table 3, the first number set of resource blocks is {1} and the second number set of resource blocks is {2 }. The number of indexes of candidate initial resource blocks corresponding to the first resource block number set is 3, and the first resource block number set is associated with the first repetition number set; the number of the indexes of the candidate initial resource blocks corresponding to the second resource block number set is 2, and the second resource block number set is associated with the second repetition number set.

Wherein the first set of repetition times has 8 repetition times, e.g., { n }₁,n ₂,n ₃,n ₄,n ₅,n ₆,n ₇,n ₈}. The second repeat number set has 4 repeat numbers which can be n₁,n ₂,n ₃,n ₄,n ₅,n ₆,n ₇,n ₈4 kinds of them. For example, { n }₁,n ₂,n ₃,n ₄}, or { n₁,n ₃,n ₅,n ₇}, or { n₂,n ₄,n ₆,n ₈In which n is₁,n ₂,n ₃,n ₄,n ₅,n ₆,n ₇,n ₈Is a positive integer. Alternatively, n₁<n ₂<n ₃<n ₄<n ₅<n ₆<n ₇<n ₈。

Based on table 2, the number of resource blocks, candidate starting resources, and the number of repetitions are 16 in total, that is, 3 × 8+2 × 4 is 2 or 32⁵. Thus, the 32 combinations can be represented by 5 bits (bits) in the control information.

Optionally, the indexes of the 3 candidate starting resource blocks corresponding to the first resource block number set may be three of the indexes of the 6 resource blocks. For example {0, 2, 4} or {1, 3, 5} or {0, 1, 2} or {3, 4, 5 }. The index of the 2 candidate starting resource blocks corresponding to the second resource block number set may be 2 of the 6 resource blocks. For example, {0, 2} or {2, 4 }.

In order to avoid collision while improving the utilization rate of resources, indexes of corresponding candidate resource blocks can be associated with different resource block number sets. For example, the index of the candidate starting resource block associated with the first set of resource block numbers may be {3, 4, 5}, and the index of the candidate starting resource block associated with the second set of resource block numbers may be {0, 2 }.

Based on the above description, in the conventional combination method, each combination composed of the number of resource blocks, the starting resource block, and the number of repetitions is selected from the plurality of resource block numbers, the plurality of starting resource blocks, and the plurality of repetitions specified in the communication protocol, so that the number of combinations that can be recognized between the first communication device and the second communication device is large, and accordingly, the number of bits occupied in the control information is large in order to represent the large number of combinations.

The embodiment of the present application further provides a communication method, which reduces the total number of final optional combinations by reducing the selection range of any one parameter of the number of optional multiple resource blocks, multiple starting resource blocks, and multiple repetition times, and is favorable for reducing the number of bits occupied by the combinations represented in the control information.

The following describes a communication method according to an embodiment of the present application with reference to fig. 3, and fig. 3 is a schematic flowchart of the communication method according to the embodiment of the present application. The method shown in fig. 3 includes step 310 and step 320. It should be noted that the method of the embodiment of the present application may be applied to a scenario in which the network device and the terminal device in fig. 1 communicate, where the first communication device may be the terminal device, and the second communication device may be the network device. The scheme of the embodiment of the application can also be applied to a D2D communication scenario, and the first communication device and the second communication device in the following description may be two terminal devices that communicate with each other. It should also be understood that the terms referred to hereinafter are the same as the terms referred to in the method illustrated in FIG. 2, and are intended to have the same meaning, and therefore, for brevity, will not be described again here.

310, a first communications device receives control information sent by a second communications device, where the control information indicates at least one of a starting resource block allocated, a number L of resource blocks allocated, and a number N of repetitions for the first communications device, where the number L of resource blocks is indicated from a first set of numbers of resource blocks, and the first set of numbers of resource blocks includes one or more numbers of resource blocks; and/or the starting resource block is selected from a first set of starting resource blocks, the first set of starting resource blocks comprising one or more starting resource blocks; and/or the number of repetitions N belongs to a first set of repetitions comprising one or more repetitions.

The first set of resource block numbers is a subset of a preset set of resource block numbers, where the preset set of resource block numbers includes all selectable resource block numbers, and all selectable resource block numbers may be all or part of resource block numbers specified by a communication protocol. For example, the number of resource blocks included in the resource block number set may be all resource blocks of one narrowband.

The first starting resource block set is a subset of a preset starting resource block set, wherein the preset starting resource block set may include all starting resource blocks which can be selected, and all starting resource blocks which can be selected may be all or part of starting resource blocks specified by a communication protocol.

The first set of repetition times is a subset of the preset repetition times, where the preset repetition times include all selectable repetition times, where all selectable repetition times may be all or part of the starting resource block specified by the communication protocol.

And 320, the first communication device sends a data channel to the second communication device according to the control information.

The following describes a manner of associating the number of resource blocks with the number of starting resource blocks (or referred to as candidate starting resources) in this embodiment, taking the first set of resource block numbers as an example. In the following description, the association method nine and the association method ten focus on the association method of the number of resource blocks and the number of starting resource blocks, and the number of repetitions associated with the first set of resource block numbers is not limited.

It should be noted that the "first set of numbers of resource blocks" referred to in fig. 3 may be the "first set of numbers of resource blocks" referred to in fig. 2, and thus, the scheme shown in fig. 2 may be used in combination with the scheme shown in fig. 3, that is, the association manner between the number of resource blocks in a certain set of numbers of resource blocks in the plurality of sets of numbers of resource blocks shown in fig. 2 and the starting resource block is described. Of course, the meaning of the "first set of number of resource blocks" referred to in fig. 3 may also be different from the meaning of the "first set of number of resource blocks" referred to in fig. 2, and at this time, the method shown in fig. 3 and the method shown in fig. 2 may be a decoupled method.

In association nine, when the first resource block number set is { a, b, c, d }, where a, b, c, d representing different resource block numbers are positive integers, and a < b < c < d, 4 specific implementations are described below in connection with association nine (one) to association nine (four).

(I), the number of the initial resource blocks in the first initial resource block set related to the number a of the resource blocks is 3; and/or the number of starting resource blocks in the first starting resource block set associated with the resource block number b is 2; and/or the number of starting resource blocks in the first starting resource block set associated with the resource block number c is 2; and/or the number of starting resource blocks in the first starting resource block set associated with the number d of resource blocks is 1.

And a correlation method ten, where the first set of resource block numbers is { a, b }, where a and b representing different numbers of resource blocks are positive integers and a < b, 2 specific implementations are described below in conjunction with the correlation method ten (one) and the correlation method ten (two).

(I), the number of the starting resource blocks in the first starting resource block set related to the resource block number a is 3, and the number of the starting resource blocks in the first starting resource block set related to the resource block number b is 1.

(II), the number of the starting resource blocks in the first starting resource block set related to the number a of the resource blocks is 6, and the number of the starting resource blocks in the first starting resource block set related to the number b of the resource blocks is 2.

Optionally, in the ninth to tenth related manners, a is 1, and b is 2; or, a is 1, b is 2, c is 4, and d is 6; or a is 1, b is 2, c is 3 and d is 4.

The first set of resource block numbers in association manners nine to ten may be associated with a set of repetition times, i.e., a first set of repetition times, which is described in detail below with reference to tables 4 to 6. It should be noted that the specific values shown in tables 4 to 6 are only for helping understanding the scheme of the embodiment of the present application, and do not limit the embodiment of the present application. The number of resource blocks in tables 4 to 6 may be obtained based on a combination of the number of resource blocks supported in the communication protocol. For example, the first set of resource block numbers may be {1, 2, 3, 4} or the like in addition to {1, 2, 4, 6} listed in tables 4 to 5. For another example, the number of 2 resource blocks included in the first set of resource block numbers shown in table 6 may be {2, 4} or the like in addition to {1, 2 }.

The specific implementation shown in tables 4 to 6 is described by taking the allocation of resources in a narrowband, or partial Bandwidth (BWP), as an example. For example, it is assumed that 6 resource blocks are included in a narrowband or BWP, and the indexes of the resource blocks in the narrowband are 0, 1, 2, 3, 4, and 5 in sequence.

TABLE 4

In table 4, the first set of resource block numbers is {1, 2, 4, 6}, and the first set of resource block numbers is associated with the first set of repetition times. The number of the indexes of the candidate initial resource block corresponding to the resource block number 1 is 2, the number of the indexes of the candidate initial resource block corresponding to the resource block number 2 is 3, the number of the indexes of the candidate initial resource block corresponding to the resource block number 4 is 2, and the number of the indexes of the candidate initial resource block corresponding to the resource block number 6 is 1.

Optionally, there are 4 repetitions in the first set of repetitions, i.e., { n }₁,n ₂,n ₃,n ₄}，n ₁,n ₂,n ₃,n ₄Is a positive integer. Alternatively, n₁<n ₂<n ₃<n ₄。

Based on table 4, the number of resource blocks, the candidate starting resource, and the number of repetitions are 32 in total, that is, 2 × 4+3 × 4+2 × 4+1 × 4 is 32 or 2⁵. Thus, the 32 combinations can be represented by 5 bits (bits) in the control information.

Optionally, the indexes of the 2 candidate starting resource blocks corresponding to the resource block number 1 may be two of the indexes of the 6 resource blocks. For example {0, 3} or {0, 1} or {0, 2} or {4, 5} or {0, 4 }. The index of 3 candidate starting resource blocks corresponding to the resource block number 2 may be 3 of the above 6 resource blocks. For example {0, 2, 4} or {0, 1, 2} or {1, 3, 5 }. The index of 2 candidate starting resource blocks corresponding to the resource block number 4 may be 2 of the above 6 resource blocks. For example, {0, 2 }. The index of 1 candidate starting resource block corresponding to the resource block number 6 may be fixed to 1 of the 6 resource blocks. For example, fixed to {0 }.

In summary, to avoid collision, indexes of corresponding candidate resource blocks may be associated for different numbers of resource blocks. For example, the index of the candidate starting resource block associated with resource block number 1 may be 4 or 5, the index of the candidate starting resource block associated with resource block number 2 may be 0, 2 or 4, the index of the candidate starting resource block associated with resource block number 4 may be 0, and the index of the candidate starting resource block associated with resource block number 6 may be 0.

In table 5, the first set of resource block numbers is {1, 2, 4, 6}, and the first set of resource block numbers is associated with the first set of repetition times. The number of the indexes of the candidate initial resource block corresponding to the resource block number 1 is 3, the number of the indexes of the candidate initial resource block corresponding to the resource block number 2 is 3, the number of the indexes of the candidate initial resource block corresponding to the resource block number 4 is 1, and the number of the indexes of the candidate initial resource block corresponding to the resource block number 6 is 1.

Based on table 5, the number of resource blocks, the candidate starting resource, and the number of repetitions are 32 in total, that is, 3 × 4+3 × 4+1 × 4 is 32 or 2⁵. Thus, the 32 combinations can be represented by 5 bits (bits) in the control information.

Optionally, the indexes of the 3 candidate starting resource blocks corresponding to the resource block number 1 may be three of the indexes of the 6 resource blocks. For example {0, 2, 4} or {1, 3, 5} or {0, 1, 2 }. The index of 3 candidate starting resource blocks corresponding to the resource block number 2 may be 3 of the above 6 resource blocks. For example {0, 2, 4} or {0, 1, 2} or {1, 3, 5 }. The index of 1 candidate starting resource block corresponding to the resource block number 4 may be fixed to 1 of the 6 resource blocks. For example, fixed to {0 }. The index of 1 candidate starting resource block corresponding to the resource block number 6 may be fixed to 1 of the 6 resource blocks. For example, fixed to {0 }.

In summary, to avoid collision, indexes of corresponding candidate resource blocks may be associated for different numbers of resource blocks. For example, the indexes of the candidate starting resource blocks associated with resource block number 1 may be 3, 4, and 5, the indexes of the candidate starting resource blocks associated with resource block number 2 may be 0, 1, and 2, the indexes of the candidate starting resource blocks associated with resource block number 4 may be 0, and the indexes of the candidate starting resource blocks associated with resource block number 6 may be 0.

TABLE 6

In table 6, the first set of resource block numbers is {1, 2}, and the first set of resource block numbers is associated with the first set of repetition times. The number of the indexes of the candidate initial resource block corresponding to the resource block number 1 is 3, and the number of the indexes of the candidate initial resource block corresponding to the resource block number 2 is 1.

Based on table 6, the number of resource blocks, candidate starting resources, and the number of repetitions are 16 in total, that is, 3 × 4+1 × 4-16-2⁴. Thus, the 16 combinations can be represented by 4 bits in the control information.

Optionally, the indexes of the 3 candidate starting resource blocks corresponding to the resource block number 1 may be three of the indexes of the 6 resource blocks. For example {0, 2, 4} or {1, 3, 5} or {0, 1, 2 }. The index of 1 candidate starting resource block corresponding to the resource block number 2 may be 1 of the above 6 resource blocks. For example, {0} or {4 }.

In summary, to avoid collision, indexes of corresponding candidate resource blocks may be associated for different numbers of resource blocks. For example, the index of the candidate starting resource block associated with resource block number 1 may be 3, 4, or 5, and the index of the candidate starting resource block associated with resource block number 2 may be 0.

Based on the first resource block set shown in table 6, there are many ways of associating the number of resource blocks in the first resource block set, the number of indexes of candidate starting resource blocks, and the first repetition number set.

For example, when the index of the candidate resource block associated with resource block number 1 is 3, and the index of the candidate resource block associated with resource block number 2 is 1, if the first repetition number set includes 2 repetition numbers, the combination of the resource block number, the candidate start resource, and the repetition number is 8 in total, that is, 3 × 2+1 × 2-8-2³Thus, 3 bits can be used to represent the above 8 combinations in the control information. When the first repetition number set includes 4 repetition numbers, the number of resource blocks, the candidate start resource, and the combination of the repetition numbers are 16 in total, that is, 3 × 4+1 × 4-16-2⁴Thus, the 16 combinations can be represented by 4 bits in the control information.

For example, when the index of the resource block candidate associated with the resource block number 1 is 6, and the index of the resource block candidate associated with the resource block number 2 is 2, if the first repetition number set includes 4 repetition numbers, the combination of the resource block number, the candidate starting resource, and the repetition number is 32 in total, that is, 6 × 4+2 × 4 ═ 32 ═ 2⁵Thus, the 32 combinations can be represented by 5 bits in the control information.

In general, the starting resource block used by the first communication device may be directly selected from candidate starting resource blocks associated with the set of numbers of resource blocks, that is, for each number of resource blocks, the number of candidate starting resource blocks to be selected is fixed, and in order to improve flexibility of a method for allocating the starting resource block, the embodiments of the present application further provide a way for determining the starting resource block.

That is, the method shown in fig. 2 or fig. 3 further includes that the first communication device receives offset information sent by the second communication device, where the offset information is used to indicate an offset of the starting resource block. Accordingly, the first communication device may determine, according to the starting resource block allocated to the first communication device and the offset of the starting resource block, the starting resource block occupied by the data channel, that is, the starting resource block occupied by the first communication device for finally transmitting the data channel.

There are various implementation manners for determining the starting resource block occupied by the data channel according to the starting resource block allocated to the first communication device and the offset of the starting resource block, which is not limited in the embodiment of the present application. For example, if the index of the starting resource block occupied by the data channel is denoted by X, the index of the starting resource block allocated to the first communication device is denoted by Y, and the offset of the starting resource block is denoted by f, the index of the starting resource block occupied by the data channel is X + f. Or, the index X of the starting resource block occupied by the data channel is (Y + f) mod T, where T is a predetermined integer.

Optionally, T is the number of resource blocks contained in one narrowband (or BWP).

Optionally, the offset information may be carried in a higher layer signaling or the control information.

It should be understood that, if the second communication device does not configure the first communication device with the transmission offset information, the first communication device uses the above-mentioned starting resource block allocated to the first communication device as the starting resource block occupied by the transmission data channel.

Optionally, the above scheme that the allocation (including the starting resource block and the number of resource blocks) and the number of repetitions of the 3-to 5-bit indication resource blocks in the occupied control information may be applied to a terminal device supporting the cemobe mode b in the prior art. Currently, for a terminal device supporting CEModeB, it is necessary to occupy 5 bits to 6 bits in the control information to indicate allocation and repetition times of resource blocks in a narrowband, which is beneficial to reducing the number of bits indicating allocation and repetition times of resource blocks in the control information.

Optionally, the above scheme that the allocation (including the starting resource block and the number of resource blocks) and the number of repetitions of the 4-to 5-bit indication resource blocks in the occupied control information may be applied to a terminal device supporting CEModeA in the prior art. Currently, for a terminal device supporting CEModeA, it is necessary to occupy 7 bits in the control information to indicate allocation and repetition times of resource blocks in a narrowband, which is beneficial to reducing the number of bits indicating allocation and repetition times of resource blocks in the control information.
