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, a communication device (e.g., a terminal device) is generally allocated a Resource Block (RB) used for transmitting a data channel using control information. In the scenario where the terminal device communicates with the network device, the control information may be downlink control information (downlink control information, DCI). After receiving the control information, the communication device may determine parameters such as RB occupied by the transmission data channel and the repetition number of the transmission data channel according to the control information. The RB occupied by the transmission data channel may be determined by the start RB and the RB length, and the repetition number may be selected from 4 repetition numbers specified in the communication protocol.

Currently, when determining the three parameters (i.e. the number of resource blocks, the initial resource block and the repetition number) for the communication device, each resource block number needs to be combined with each of the 4 repetition numbers to obtain an overall combination mode, so that other communication devices can determine one combination from the overall combination modes for the communication device to instruct the communication device to transmit data, regardless of the quality of the channel. However, the above method of obtaining all combinations is not reasonable.

In the embodiment of the present application, one repetition number set is associated with each resource block number set, and thus, the repetition number allocated to the first communication device is determined from the first repetition number set associated with the resource block number L. That is, the number L of resource blocks is only required to be combined with the repetition number contained in the first repetition number set, so that the situation that the repetition number sets associated with all the number of resource blocks in the prior art are the same is avoided, and the rationality of the combination mode between the number of resource blocks and the repetition number is improved.

Detailed Description

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

Fig. 1 is a wireless communication system 100 to which embodiments of the present application apply. 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 the coverage area.

Fig. 1 illustrates one network device and two terminals, alternatively, the wireless communication system 100 may include multiple network devices and each network device may include other numbers of terminals within a coverage area, which is not limited in this embodiment.

Optionally, the wireless communication system 100 may further include a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be appreciated that the technical solution of the present application may be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, general packet radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) system, long term evolution advanced (Advanced long term evolution, LTE-a) system, universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), new air interface (New Radio Access Technology, NR), 5G, etc.

It should also be appreciated that in embodiments of the present application, the terminal devices may include, but are not limited to, terminal devices applied in the internet of things, e.g., may be terminal devices in an access NB-IoT (which may be referred to as "NB-IoT terminals"): intelligent meter reading equipment, logistics tracking equipment, environment monitoring equipment and the like; the Terminal may also include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile Telephone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), etc., which may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), such as a Mobile Telephone (or "cellular" Telephone), a computer with wireless communication capabilities, etc., and 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 transmitting and receiving point (Transmit and Receive Point, TRP), or an access point, where the base station may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved Node B in LTE, an eNB, or an e-NodeB, or a base station (gNB) in NR or 5G, which is not specifically limited in this embodiment of the present application.

The conventional resource allocation method is described below based on the communication system shown in fig. 1. The network device sends downlink control information to the terminal device, and indicates the resource block allocated to the terminal device and the repetition number through the downlink control information, so as to instruct the terminal device to transmit the data channel on the resource block according to the repetition number. Wherein, the resource block allocated to the terminal device is indicated by the initial resource block and the number of resource blocks (also called as "resource block length").

A plurality of initial resource blocks, a plurality of resource block numbers and a plurality of repetition times are specified in the current communication protocol. When the network device determines the resource blocks, the number of the resource blocks and the repetition number for the terminal device, a suitable combination can be selected for the terminal device from a plurality of combinations obtained by the plurality of initial resource blocks, the plurality of resource block numbers and the plurality of repetition numbers.

The plurality of combinations includes a combination of each number of resource blocks and each of the plurality of (e.g., 4) repetition times. However, the combination of the number of the combined resource blocks and the repetition number is not reasonable, so that the number of combinations to be recognized between the network device and the terminal device is increased, which leads to an increase of the cost of the 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 preferably select a larger number of repetitions when selecting the number of repetitions. For another example, if the channel quality is better, the reliability of data transmission can be guaranteed to a certain extent through the channel quality, and the network device can allocate a longer number of resource blocks for the terminal device, so as to improve the efficiency of data transmission of the terminal device. The network device may also typically select a smaller number of repetitions due to 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 this 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 number.

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 of an embodiment of the present application. The method shown in fig. 2 includes steps 210 through 220. It should be noted that, the method of the embodiment of the present application may be applicable to the 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, where the first communication device and the second communication device may be two terminal devices that communicate with each other.

210, the first communication device receives control information indicating the number of resource blocks L and the number of repetitions N allocated to the first communication device. 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 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, for example, may be the length of the resource blocks mentioned above. The plurality of resource blocks may be determined according to the number L of resource blocks, and may be continuous or discontinuous.

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

Each of 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 resource block number sets in the plurality of resource block number sets are associated with different repetition number sets, and the remaining resource block number sets in the plurality of resource block number sets may be associated with the same repetition number set.

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

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

The "number of resource blocks L" may be the number of allocated resource blocks or the length of allocated resource blocks. The number of the resource blocks is not limited, wherein L is only a symbol, and is only used for distinguishing from other resource blocks, and the number is not represented. The number of resource blocks L may be replaced with "resource block length" or "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 the value. The above-described "number of repetitions N" may be replaced with "first number of repetitions".

Note that, the number of resource blocks L and the number of repetitions N may be carried in the same field in the control information, and the number of resource blocks L and the number of repetitions N may also be carried in different fields in the control information.

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

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

If the repetition number N is the repetition number for transmitting 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 by using the repetition number for transmitting 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 number of resource blocks allocated to the first communication device is relatively large when the number of resource blocks is relatively small, and besides the fact that the number of resource blocks allocated to the first communication device is relatively small when the channel quality is relatively poor as described above, another situation may exist that the data volume of the data to be transmitted by the first communication device is relatively small, and no large number of resource blocks is needed.

It can be seen that, when the association between the number of resource blocks and the number of repetition sets is established, if the number of resource blocks in the number of resource blocks is large, the application is simpler, that is, the channel quality is better, so that the number of repetition times included in the associated number of repetition sets can be smaller, that is, the number of alternative repetition times in the associated number of repetition sets is smaller. If the number of resource blocks in the set of the number of resource blocks is smaller, the applicable situation is complex, including the situations that the channel quality is poor and the data amount of the data to be transmitted is smaller, so that the number of the repetition times contained in the set of the associated repetition times can be larger, that is, the number of the repetition times available for selection in the set of the associated repetition times is larger, and thus, a more combined mode can be obtained according to the set of the number of the resource blocks and the set of the repetition times, so as to adapt to the situations.

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 resource block number in the second resource block number set is greater than a maximum resource block number in the first resource block number set, and a number of repetition numbers in the second repetition number set is not greater than (i.e., less than or equal to) a number of repetition numbers 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 not be a 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 includes a first resource block number set and a second resource block number set, wherein the number of resource blocks in the first resource block number set is 1, the number of resource blocks in the second resource block number set is 2, and the first repetition number set associated with the first resource block number set is { n } ₁ ，n ₂ ，n ₃ ，n ₄ A second set of repetition times associated with the second set of resource block numbers is { n } ₁ ，n ₄ N representing the value of the number of repetitions ₁ ，n ₂ ，n ₃ ，n ₄ Is a positive integer.

Or, the minimum number of resource blocks in the first set of resource blocks is greater than the maximum number of resource blocks in the second set of resource blocks, and the number of repetition times in the first set of repetition times is not greater than (i.e. less than or equal to) the number of repetition times in the second set of repetition times. Optionally, the first repetition number set is a subset of the second repetition number set. Of course, there may not be a 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 repetition number sets so as to control the number of the resource block number and repetition number combinations, thereby controlling bit occupied by the indicated resource block number and the repetition number in the control information.

And the first association mode is as follows: the plurality of resource block number sets comprise a third resource block number set { c, d }, the first resource block number set { a }, the second resource block number set { b }, the first repetition number set comprising 4 repetition numbers, the second repetition number set comprising 2 repetition numbers, the third repetition number set associated with the third resource block number set comprising 1 repetition number, wherein a, b, c, d representing different resource block numbers is a positive integer, and a < b < c < d.

In a second association manner, the first set of resource blocks is { a, b }, the second set of resource blocks is { c, d }, the set of repetition times associated with the first set of resource blocks includes 3 types of repetition times, the second set of repetition times includes 2 types of repetition times, a, b, c, d representing different numbers of resource blocks is a positive integer, and a < b < c < d.

In a third association manner, the first set of resource blocks is { a }, the second set of resource blocks is { b, c, d }, the first set of repetition times comprises 4 repetition times, the second set of repetition times comprises 2 repetition times, a, b, c, d representing different numbers of resource blocks is a positive integer, and a < b < c < d.

In a fourth association manner, the first set of resource block numbers is { e }, the second set of resource block numbers is { f }, the first set of repetition times comprises 8 repetition times, the second set of repetition times comprises 4 repetition times, wherein e and f representing different resource block numbers are positive integers, and e < f.

It should be noted that, the specific value of the repetition number in the first to fourth association ways is not limited in the embodiment of the present application, and the repetition number specified in the current communication protocol and the repetition number 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 the transmission data channel.

That is, 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 communication device sending a data channel to the second communication device according to the number L of resource blocks, the number N of repetitions and the initial resource block.

It should be noted that, the initial resource block may be predefined in the communication protocol, or may be indicated by the second communication device to the first 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 blocks so as to control the number of the combination of the number of the resource blocks and the candidate initial resource blocks, thereby controlling bit positions occupied by the number L of the indicated resource blocks and 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 sets of resource block numbers may be associated with the same candidate starting resource block, i.e., one or more candidate starting resource blocks with which each set of resource block numbers may be associated are the same. Of course, the plurality of sets of resource block numbers may also be associated with a plurality of candidate starting resource block sets, where the candidate starting resource block sets include one or more candidate starting resource blocks. Wherein candidate initial resource block sets associated with at least two resource block number sets in the plurality of resource block number sets are different. The association of the resource block number set with the candidate starting resource block is described below in connection with association five through association eight.

In the fifth association mode, if the first set of resource blocks is { a }, the second set of resource blocks is { b }, and the third set of resource blocks is { c, d }, the association mode of the number of resource blocks and the starting resource block may be subdivided into the following three association modes five (1) to five (2).

And in the association mode five (1), each resource block number in the first resource block number set is associated with 2 candidate initial resource blocks, each resource block number in the second resource block number set is associated with 3 candidate initial resource blocks, and each resource block number in the third resource block number set is associated with 1 candidate initial resource block.

And (5) in the association mode five (2), 3 candidate initial resource blocks are associated with each resource block number in the first resource block number set, 1 candidate initial resource block is associated with each resource block number in the second resource block number set, and 1 candidate initial resource block is associated with each resource block number in the third resource block number set.

In the eighth association mode, the first number of resource blocks is { a }, the second number of resource blocks is { b }, the number of resource blocks a in the first number of resource blocks is associated with 3 candidate initial resource blocks, and the number of resource blocks b in the first number of resource blocks is associated with 2 candidate initial resource blocks.

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

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

Alternatively, a=1, b=2; alternatively, a=1, b=2, c=4, d=6; alternatively, a=1, b=2, c=3, d=4.

The association relationship between the resource block number set indicated by the first association manner to the fourth association manner and the repetition number may be used in combination with the association relationship between the resource block number set indicated by the fifth association manner to the sixth association manner and the initial resource block. For example, association one may be used in combination with association five, association two may be used in combination with association six, and association three may be used in combination with association seven.

3 specific implementations are listed below in conjunction with tables 1 through 3. It should be noted that the specific values shown in tables 1 to 3 are only for aiding in understanding the schemes of the embodiments of the present application, and are not limited to the embodiments of the present application.

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

TABLE 1

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

Wherein the first repetition number set has 4 repetition numbers, i.e., { n ₁ ，n ₂ ，n ₃ ，n ₄ }. The second repetition number is 2, which can be n ₁ ，n ₂ ，n ₃ ，n ₄ Two of which are described below. For example, the second set of repetition times is { n ₂ ，n ₄ }. Alternatively, the second set of repetition times is { n } ₁ ，n ₃ }. Alternatively, the second set of repetition times is { n } ₃ ，n ₄ }. The third repetition number is 1, which can be n ₁ ，n ₂ ，n ₃ ，n ₄ 1 of (a) are provided. For example, the third repetition number set is { n ₁ }. Alternatively, the third repetition number set is { n } ₂ N is }, where n ₁ ，n ₂ ，n ₃ ，n ₄ Is a positive integer. Alternatively, n ₁ ＜n ₂ ＜n ₃ ＜n ₄ 。

Based on table 1, the number of resource blocks, the number of candidate starting resources, and the number of repetitions combined are 16 in total, i.e., 2×4+3×2+1×1+1×1=16=2 ⁴ . Thus, the control information can be represented by 4 bits (bits) for the 16 combinations.

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

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

For example, the number of resource blocks allocated to the communication device 1 is 2, belongs to the second set of resource blocks, and indexes of candidate starting resource blocks associated with the second set of resource blocks are 0,2,4. The number of resource blocks allocated to the communication device 1 is 4, which belongs to the third resource block number set, and the index of the candidate initial resource block associated with the third resource block number set is 0, and in order to avoid collision, among the indexes 0,2, and 4 of the candidate initial resource block associated with the second resource block number set, the index of the candidate initial resource block preferentially selected is 4. Thus, 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.

To sum up, in order to avoid collision, indexes of corresponding candidate resource blocks can be associated for different sets of resource block numbers. For example, the indexes of the candidate initial resource blocks associated with the first resource block number set are 0 and 4, the indexes of the candidate initial resource blocks associated with the second resource block number set may be 0,2 and 4, and the indexes of the candidate initial resource blocks associated with the second resource block number set may be 0.

TABLE 2

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

Wherein the first repetition number set { n } ₁ ，n ₂ ，n ₃ ，n ₄ There are 4 repetition times. The second repetition number set has 2 repetition numbers, which may be n ₁ ，n ₂ ，n ₃ ，n ₄ Two of which are described below. For example, the second set of repetition times is { n ₂ ，n ₄ }. Alternatively, the second set of repetition times is { n } ₁ ，n ₃ }. Alternatively, the second set of repetition times is { n } ₃ ，n ₄ }. The third repetition number set has 1 repetition number, which may be n ₁ ，n ₂ ，n ₃ ，n ₄ 1 of (a) are provided. For example, the third repetition number set is { n ₁ }. Alternatively, the third repetition number set is { n } ₂ N is }, where n ₁ ，n ₂ ，n ₃ ，n ₄ Is a positive integer. Alternatively, n ₁ ＜n ₂ ＜n ₃ ＜n ₄ 。

Based on table 2, the number of resource blocks, the number of candidate starting resources, and the number of repetitions combined are 16 in total, i.e., 2×4+2×2+1×2+1×2=16=2 ⁴ . Thus, the control information can be represented by 4 bits (bits) for the 16 combinations.

Alternatively, the indexes of the 2 candidate starting resource blocks corresponding to the first resource block number set may be two 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 set of resource block numbers may be 2 of the 6 resource blocks. For example {0,2} or {2,4} or {0,4} or {1,4}. The index of the 1 candidate starting resource block corresponding to the third set of resource blocks 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 for different sets of resource block numbers. For example, the indexes of candidate initial resource blocks associated with the first resource block number set are 0 and 4, the indexes of candidate initial resource blocks associated with the resource block number 2 in the second resource block number set can be 1 and 4, and the indexes of candidate initial resource blocks associated with the resource block numbers 4 and 6 in the second resource block number set can be 0.

TABLE 3 Table 3

In table 3, the first set of resource block numbers is {1} and the second set of resource block numbers 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 a first repetition number set; the number of 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 a second repetition number set.

Wherein the first set of repetition numbers has 8 repetition numbers, for example { n } ₁ ，n ₂ ，n ₃ ，n ₄ ，n ₅ ，n ₆ ，n ₇ ，n ₈ }. The second repetition number is 4, which can be n ₁ ，n ₂ ，n ₃ ，n ₄ ，n ₅ ，n ₆ ，n ₇ ，n ₈ 4 of (a) are provided. For example, { n ₁ ，n ₂ ，n ₃ ，n ₄ Or { n }, or ₁ ， _n3 ，n ₅ ，n ₇ Or { n }, or ₂ ，n ₄ ，n ₆ ，n ₈ N is }, where n ₁ ，n ₂ ，n ₃ ，n ₄ ，n ₅ ，n ₆ ，n ₇ ，n ₈ Is a positive integer. Alternatively, n ₁ ＜n ₂ ＜n ₃ ＜n ₄ ＜n ₅ ＜n ₆ ＜n ₇ ＜n ₈ 。

Based on a table2, the number of resource blocks, the combination of candidate starting resources and the repetition number is 16, namely 3×8+2×4=32=2 ⁵ . Thus, the above 32 combinations can be represented by 5 bits (bits) in the control information.

Alternatively, the indexes of the 3 candidate starting resource blocks corresponding to the first resource block number set may be three 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 set of resource block numbers 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 for different sets of resource block numbers. For example, the index of the candidate starting resource block associated with the first set of resource block numbers is {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 combining manner, each combination of the number of resource blocks, the number of start resource blocks and the number of repetitions is selected from a plurality of resource blocks, a plurality of start resource blocks and a plurality of repetitions specified in the communication protocol, so that the number of combinations that can be identified between the first communication device and the second communication device is relatively large, and accordingly, in order to be able to represent a relatively large number of combinations, the number of bits occupied in the control information is relatively large.

The embodiment of the application also provides a communication method, which reduces the total number of final optional combinations by reducing the selection range of any parameter of the number of optional resource blocks, the number of initial resource blocks and the number of repetition times, thereby being beneficial to reducing the number of bits occupied by the indicated combinations in the control information.

The communication method according to the embodiment of the present application is described below 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 steps 310 and 320. It should be noted that, the method of the embodiment of the present application may be applicable to the 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 D2D communication, where the first communication device and the second communication device 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 those referred to in the method shown in fig. 2, and their meanings are also the same, and are not repeated here for brevity.

310, the first communication device receives control information sent by the second communication device, where the control information indicates at least one of an allocated initial resource block, an allocated resource block number L and a repetition number N for the first communication device, where the resource block number L is indicated from a first resource block number set, and the first resource block number set includes one or more resource block numbers; 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, the first set of repetitions comprising one or more repetitions.

The first resource block number set is a subset of a preset resource block number set, wherein the preset resource block number set contains the total number of the resource blocks which can be selected, and the total number of the resource blocks which can be selected can be the total number or part of the number of the resource blocks specified by a communication protocol. For example, the number of resource blocks included in the set of number of resource blocks may be all resource blocks of one narrowband.

The first set of starting resource blocks is a subset of a preset set of starting resource blocks, where the preset set of starting resource blocks may include all starting resource blocks that may be selected, where all starting resource blocks that may be selected may be all or part of starting resource blocks specified by a communication protocol.

The first repetition number set is a subset of the preset repetition number, wherein the preset repetition number combination includes an optional total repetition number, and the optional total repetition number may be all or part of a starting resource block specified by a communication protocol.

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

The method of associating the number of resource blocks with the number of starting resource blocks (or candidate starting resources) in the embodiment of the present application is described below by taking the first set of the number of resource blocks as an example. In the following, the association mode nine and the association mode ten point introduce the association mode of the number of resource blocks and the number of initial resource blocks, and the number of repetition associated with the first resource block number set is not limited.

It should be noted that, the "first set of resource block numbers" referred to in fig. 3 may be the "first set of resource block numbers" 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, a manner of associating the number of resource blocks in a certain set of resource block numbers in the plurality of sets of resource block numbers shown in fig. 2 with the starting resource block is described. Of course, the "first set of resource blocks" related to fig. 3 may also have a meaning different from that of the "first set of resource blocks" related to fig. 2, and in this case, the method shown in fig. 3 and the method shown in fig. 2 may be decoupled methods.

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

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

And in the association manner ten, the first set of resource block numbers is { a, b }, where a and b representing different resource block numbers are positive integers, and a < b, and in the case of a < b, 2 specific implementation manners are described below in combination with the association manner ten (one) and the association manner ten (two).

(one), the number of the initial resource blocks in the first initial resource block set associated with the resource block number a is 3, and the number of the initial resource blocks in the first initial resource block set associated with the resource block number b is 1.

(II) the number of the initial resource blocks in the first initial resource block set associated with the resource block number a is 6, and the number of the initial resource blocks in the first initial resource block set associated with the first resource block number b is 2.

Optionally, in the above-mentioned association manners nine to ten, a=1, b=2; alternatively, a=1, b=2, c=4, d=6; alternatively, a=1, b=2, c=3, d=4.

The first set of resource block numbers in association nine through association ten may be associated with one set of repetition times, i.e., a first set of repetition times, as described in detail below in connection with tables 4 through 6. It should be noted that the specific values shown in tables 4 to 6 are only for aiding in understanding the schemes of the embodiments of the present application, and are not limited to the embodiments of the present application. The number of resource blocks in tables 4 to 6 may be combined based on 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 implementations shown in tables 4 through 6 are illustrated by way of example as allocating resources within a narrowband, or fractional Bandwidth (BWP). If it is assumed that 6 resource blocks are included in one narrowband or BWP, and indexes of the resource blocks in the narrowband are 0,1,2, 3, 4, and 5 in sequence.

TABLE 4 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 indexes of candidate initial resource blocks corresponding to the number 1 of the resource blocks is 2, the number of indexes of candidate initial resource blocks corresponding to the number 2 of the resource blocks is 3, the number of indexes of candidate initial resource blocks corresponding to the number 4 of the resource blocks is 2, and the number of indexes of candidate initial resource blocks corresponding to the number 6 of the resource blocks is 1.

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

Based on table 4, the number of resource blocks, the number of candidate starting resources, and the number of repetitions combined are 32 in total, i.e., 2×4+3×4+2×4+1×4=32=2 ⁵ . Thus, the above 32 combinations can be represented by 5 bits (bits) in the control information.

Alternatively, the indexes of the 2 candidate starting resource blocks corresponding to the number 1 of resource blocks 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 indexes of the 3 candidate starting resource blocks corresponding to the number 2 of the resource blocks can be 3 of the 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 number 4 of resource blocks may be 2 of the 6 resource blocks. E.g., {0,2}. The index of 1 candidate starting resource block corresponding to the number of resource blocks 6 may be fixed to 1 of the 6 resource blocks. For example, fixed to {0}.

To sum up, in order to avoid collision, indexes of corresponding candidate resource blocks can be associated for different numbers of resource blocks. For example, indexes of candidate initial resource blocks associated with the number 1 of the resource blocks are 4 and 5, indexes of candidate initial resource blocks associated with the number 2 of the resource blocks can be 0, 2 and 4, indexes of candidate initial resource blocks associated with the number 4 of the resource blocks can be 0, and indexes of candidate initial resource blocks associated with the number 6 of the resource blocks can 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 indexes of candidate initial resource blocks corresponding to the number 1 of the resource blocks is 3, the number of indexes of candidate initial resource blocks corresponding to the number 2 of the resource blocks is 3, the number of indexes of candidate initial resource blocks corresponding to the number 4 of the resource blocks is 1, and the number of indexes of candidate initial resource blocks corresponding to the number 6 of the resource blocks is 1.

Based on table 5, the number of resource blocks, the number of candidate starting resources, and the number of repetitions combined total 32, i.e., 3×4+3×4+1×4+1×4=32=2 ⁵ . Thus, the above 32 combinations can be represented by 5 bits (bits) in the control information.

Alternatively, the indexes of the 3 candidate starting resource blocks corresponding to the number 1 of resource blocks 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 indexes of the 3 candidate starting resource blocks corresponding to the number 2 of the resource blocks can be 3 of the 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 number 4 of resource blocks 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 number of resource blocks 6 may be fixed to 1 of the 6 resource blocks. For example, fixed to {0}.

To sum up, in order to avoid collision, indexes of corresponding candidate resource blocks can be associated for different numbers of resource blocks. For example, indexes of candidate initial resource blocks associated with the number 1 of the resource blocks are 3, 4 and 5, indexes of candidate initial resource blocks associated with the number 2 of the resource blocks can be 0,1 and 2, indexes of candidate initial resource blocks associated with the number 4 of the resource blocks can be 0, and indexes of candidate initial resource blocks associated with the number 6 of the resource blocks can 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 indexes of candidate initial resource blocks corresponding to the number 1 of the resource blocks is 3, and the number of indexes of candidate initial resource blocks corresponding to the number 2 of the resource blocks is 1.

Based on table 6, there are 16 combinations of the number of resource blocks, candidate starting resources and the number of repetitions, i.e. 3×4+1×4=16=2 ⁴ . Thus, the control information can be represented by 4 bits for the above 16 combinations.

Alternatively, the indexes of the 3 candidate starting resource blocks corresponding to the number 1 of resource blocks 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 number of resource blocks 2 may be 1 of the 6 resource blocks. For example {0} or {4}.

To sum up, in order to avoid collision, indexes of corresponding candidate resource blocks can be associated for different numbers of resource blocks. For example, indexes of candidate initial resource blocks associated with the number 1 of the resource blocks are 3, 4 and 5, and indexes of candidate initial resource blocks associated with the number 2 of the resource blocks can be 0.

The number of resource blocks in the first set of resource blocks, the number of indexes of candidate starting resource blocks, and the association manner between the first set of repetition times are also various based on the first set of resource blocks shown in table 6.

For example, when the index of the candidate resource block associated with the number 1 of resource blocks is 3 and the index of the candidate resource block associated with the number 2 of resource blocks is 1, if the first repetition number set includes 2 repetitions, the number of resource blocks, the candidate start resources, and the repetition number are combined 8, that is, 3×2+1×2=8=2 ³ Thus, the above 8 combinations can be represented by 3 bits in the control information. If the first repetition set includes 4 repetitions, the number of resource blocks, the candidate starting resources, and the repetition combinations are 16, i.e., 3×4+1×4=16=2 ⁴ Thus, the control information can be represented by 4 bits for the above 16 combinations.

For another example, when the index of the candidate resource block associated with the number of resource blocks 1 is 6 and the index of the candidate resource block associated with the number of resource blocks 2 is 2, if the first repetition number set includes 4 repetitions, the number of resource blocks, the candidate start resource, and the repetition number are combined together in a total of 32, that is, 6×4+2×4=32=2 ⁵ Thus, the above 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 resource block numbers, that is, the number of candidate starting resource blocks that may be selected for each resource block number is fixed, and in order to improve flexibility of a method for allocating the starting resource block, in this embodiment of the present application, a manner of determining the starting resource block is further provided.

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 the initial resource block occupied by the data channel, that is, the initial resource block occupied by the first communication device for finally transmitting the data channel, according to the initial resource block allocated to the first communication device and the offset of the initial resource block.

The implementation manner of determining the initial resource block occupied by the data channel according to the initial resource block allocated to the first communication device and the offset of the initial resource block is various, which is not limited in the embodiment of the present application. For example, 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, the offset of the starting resource block is denoted by f, and then the index x=y+f of the starting resource block occupied by the data channel. Or, the index x= (y+f) mod T of the starting resource block occupied by the data channel, where T is a predetermined integer.

Alternatively, T is the number of resource blocks that one narrowband (or BWP) contains.

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

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

Optionally, the scheme that the 3bit to 5bit indication resource block allocation (including the initial resource block and the number of resource blocks) and the repetition number in the occupancy control information are needed in the foregoing may be applied to a terminal device supporting CEModeB in the prior art. Currently, for a terminal device supporting CEModeB, it is required to occupy 5 bits to 6 bits in the control information to indicate allocation and repetition number of resource blocks in the narrowband, which is beneficial to reducing the number of bits indicating allocation and repetition number of resource blocks in the control information.

Optionally, the scheme that 4bit to 5bit indication resource block allocation (including the initial resource block and the number of resource blocks) and the repetition number in the occupancy control information are needed in the foregoing may be applied to a terminal device supporting CEModeA in the prior art. Currently, for a terminal device supporting CEModeA, it is required to occupy the number of repetition and allocation of 7 bits in the control information to indicate the resource block in the narrowband, i.e. the number of bits to be beneficial to reducing the number of repetition and allocation of the resource block in the control information.
