Description

Method and device for transmitting data and method and device for receiving data

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting data and a method and an apparatus for receiving data.

Background

As communication technology develops, the peak data transmission rate increases, and the size (e.g., the number of bits included) of a Transport Block (TB) also increases.

In order to improve the accuracy and reliability of communication, a feedback mechanism is proposed, that is, a receiving end generates feedback information for a TB, for example, (acknowledgement, abbreviated as "ACK") information or Negative acknowledgement (NACK ") information, based on a decoding structure of the received TB.

However, this TB-based feedback mechanism, once it is in error, will cause the whole TB to be retransmitted, which is certainly a waste of resources.

For this, the TB may be divided into a plurality of Code Blocks (CBs). And feedback is performed based on the CB, that is, the feedback information is directed to the CB, so that retransmission of the entire TB due to partial data transmission errors can be avoided.

However, in the feedback mechanism based on the CB, feedback information of a plurality of CBs needs to be transmitted in one feedback process, which results in a large resource overhead of the feedback information.

Accordingly, it is desirable to provide a technique that can reduce the resource overhead of feedback information.

Fig. 1 is a schematic diagram of a wireless communication system of an embodiment of the present invention. As shown in fig. 1, the communication system 100 includes a network device 102, and the network device 102 may include 1 antenna or multiple antennas, e.g.,

antennas

104, 106, 108, 110, 112, and 114. Additionally, network device 102 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.

Network device 102 may communicate with a plurality of terminal devices, such as terminal device 116 and terminal device 122. However, it is understood that network device 102 may communicate with any number of terminal devices similar to terminal device 116 or terminal device 122.

End devices

116 and 122 may be, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, and/or any other suitable device for communicating over wireless communication system 100.

As shown in fig. 1, terminal device 116 is in communication with

antennas

112 and 114, where

antennas

112 and 114 transmit information to terminal device 116 over a forward link (also called a downlink) 118 and receive information from terminal device 116 over a reverse link (also called an uplink) 120. In addition, terminal device 122 is in communication with

antennas

104 and 106, where

antennas

104 and 106 transmit information to terminal device 122 over forward link 124 and receive information from terminal device 122 over reverse link 126.

In a Frequency Division Duplex (FDD) system, forward link 118 can utilize a different Frequency band than reverse link 120, and forward link 124 can employ a different Frequency band than reverse link 126, for example.

As another example, in Time Division Duplex (TDD) systems and full Duplex (fullblex) systems, forward link 118 and reverse link 120 may use a common frequency band and forward link 124 and reverse link 126 may use a common frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of network device 102. For example, antenna groups may be designed to communicate to terminal devices in a sector of the areas covered by network device 102. A network device may transmit signals to all terminal devices in its corresponding sector through single-antenna or multi-antenna transmit diversity. During communication by network device 102 with

terminal devices

116 and 122 over

forward links

118 and 124, respectively, the transmitting antennas of network device 102 may also utilize beamforming to improve signal-to-noise ratio of

forward links

118 and 124. Moreover, mobile devices in neighboring cells can experience less interference when network device 102 utilizes beamforming to transmit to

terminal devices

116 and 122 scattered randomly through an associated coverage area, as compared to a manner in which the network device transmits signals to all of its terminal devices through single-antenna or multi-antenna transmit diversity.

At a given time, network device 102, terminal device 116, or terminal device 122 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

In addition, the communication system 100 may be a PLMN network, a D2D network, an M2M network, or other networks, and fig. 1 is a simplified schematic diagram for example, and other network devices may be included in the network, which are not shown in fig. 1.

In the embodiment of the present invention, the network device may transmit control information with a plurality of terminal devices, and the network device is similar to a process of transmitting control information with each terminal device, and for convenience of understanding, the following description will be given by taking a control information transmission process between the network device and the terminal device # a as an example.

Also, in the embodiment of the present invention, a plurality of control information for a plurality of TBs may be transmitted between the network device and the terminal device # a, and the generation and transmission processes of the control information for each TB are similar, and for ease of understanding, a description will be given below by taking as an example a process of transmitting the control information for the TB # a between the network device and the terminal device # a (hereinafter, for ease of understanding and description, referred to as the control information # a).

Fig. 2 shows a schematic interaction diagram of a method 200 for transmitting data (hereinafter, referred to as data # a for ease of understanding and explanation) for a TB # a (i.e., an example of a first TB) carried by a transmitting device and a receiving device.

It should be noted that, in the embodiment of the present invention, the data # a may be data generated by performing processing such as modulation and resource mapping on the TB # a, specifically, the CBs in each CB group included in the TB # a, and the data # a may include only the TB # a, or the data # a may include other TBs besides the TB # a, which is not particularly limited in the present invention.

As shown in fig. 2, after the transmitting device determines that TB # a (i.e., an example of the first TB) needs to be transmitted to the receiving device at S210. The transmitting device may determine the number M of CB groups that TB # a includes.

And, after determining that TB # a transmitted by the transmitting device needs to be received, the receiving end device may determine the number M of CB groups included in the TB # a.

In the embodiment of the present invention, the process of determining the number M by the transmitting device and the receiving device is similar, and here, for convenience of understanding and explanation, the process of determining the number M of the CB groups by the transmitting device is taken as an example for detailed description.

In the embodiment of the present invention, the transmitting device may divide TB # a into M CB groups according to the number a of bits included in TB # a, the maximum number Z of bits included in each coded block CB, and the maximum number X of CBs included in each CB group, that is, the value of M may be determined according to A, Z and the value of X, where a is an integer greater than zero, Z is an integer greater than zero, and X is an integer greater than zero.

In the embodiment of the present invention, the network device may first divide the TB # a into M CB groups and divide each CB group into a plurality of CBs (i.e., manner 1), or the network device may first divide the TB # a into a plurality of theoretical CBs and determine the M CB groups according to the plurality of theoretical CBs (i.e., manner 2). Next, a process of determining M CB groups in the above two modes will be described in detail.

Mode 1

In the embodiment of the present invention, since the total number of bits that need to be divided into the M CB groups is determined in the case of whether a check bit needs to be added in TB # a, the transmitting device and the receiving device may also determine the M CB groups included in TB # a according to the case of whether a check bit needs to be added in TB # a.

The condition whether the check bit needs to be added in the TB # a may be specified by a communication system or a communication protocol, or the condition whether the check bit needs to be added in the TB # a may be determined by a network device of the transmitting device and the receiving device and transmitted to the receiving device.

That is, in the embodiment of the present invention, the total number of bits that need to be currently divided into the M CB groups is denoted as: b, where T is the number of check bits added in the first transport block TB, T >0, and as described above, the value of T may be a value specified by a communication system or a communication protocol, or may also be a value determined by the network device and issued to the terminal device.

For example, if T check bits need to be added in the TB # a (e.g., as specified by the communication system or communication protocol), the transmitting device may determine the relationship between B and X × Z.

Wherein Z represents the maximum number of bits included in each coding block CB, and X represents the maximum number of CBs included in each CB group, so that "X × Z" may represent the maximum number of bits included in each CB group, where the value of X may be specified by a communication system or a communication protocol, or the value of X may also be determined by a network device and issued to a terminal device.

If B ≦ X × Z, the transmitting device may determine that the total number of bits required to be divided into M CB groups is less than the maximum number of bits that one CB group can include, and thus, the transmitting device determines that M ≦ 1. By way of example and not limitation, at this time, since T parity bits are added in TB # a, the CB group may not need to add parity bits.

If B > X Z, the transmitting device may determine that the total number of bits required to be divided into M CB groups is greater than the maximum number of bits that one CB group can include, i.e., the transmitting device needs to divide B bits into at least two CB groups, and thus, the transmitting device determines that B bits are required to be divided into at least two CB groups

Wherein the content of the first and second substances,

the rounding-up operation is shown, and the description of the same or similar cases will be omitted below.

For another example, if (e.g., communication system or communication protocol specification) no check bits need to be added in the TB # a, the transmitting device determines

In this embodiment of the present invention, since the total number of bits of each CB group is determined according to whether a parity bit needs to be added in each CB group, the transmitting device and the receiving device may further determine the number M of CB groups included in TB # a according to whether a parity bit needs to be added in each CB group, where L is 0 to indicate that no parity bit needs to be added in each CB group, and L is L0 to indicate that L0 parity bits need to be added in each CB group, and L0 is a positive integer specified by a protocol or dynamically configured. Hereinafter, the description of the same or similar cases will be omitted.

The condition whether the check bit needs to be added in each CB group may be specified by a communication system or a communication protocol, or the condition whether the check bit needs to be added in each CB group may be determined by a network device of the transmitting device and the receiving device and transmitted to the receiving device. Hereinafter, the description of the same or similar cases will be omitted.

In this embodiment of the present invention, after determining the number M of CB groups included in TB # a, the transmitting device and the receiving device may further determine the number of bits included in each CB group, and further, the transmitting device and the receiving device may further determine the number of CBs included in each CB group.

That is, in the embodiment of the present invention, the transmitting device and the receiving device may determine the number S of bits included in the CB group j of the M CB groups according to the value of M_j，j∈[1，M]And according to this S_jDetermines the number W of CBs included in the CB group j_j。

In the embodiment of the present invention, since the total number of bits of each CB group is determined according to whether a check bit needs to be added in each CB group, the sending device and the receiving device may also determine the number of CB groups included in each TB according to whether a check bit needs to be added in each CB group.

By way of example and not limitation, in embodiments of the present invention, the number S of bits included in CB group j may be determined in the following manner_j。

Based on the above determination process of the M value, it can be known that: in the M CB groups, each of the first M-1 CB groups may include the same number of bits, and the last (mth) CB group may include the same number of bits as each of the first M-1 CB groups, or the last (mth) CB group may include the number of bits smaller than the number of bits included in each of the first M-1 CB groups.

Therefore, in the embodiment of the present invention, the number of bits included in each CB group may be determined based on the position of each CB group in the M CB groups.

That is, if j < M, the transmitting device or the receiving device may determine that:

if j ═ M, the transmitting device or receiving device may determine:

based on the above determination process of the M value, it can be known that: in the M CB groups, the number of CBs included in each of the first M-1 CB groups is the same, the number of CBs included in the last (mth) CB group may be the same as the number of CBs included in each of the first M-1 CB groups, or the number of CBs included in the last (mth) CB group may be smaller than the number of CBs included in each of the first M-1 CB groups.

Therefore, in the embodiment of the present invention, the number of CBs included in each CB group may be determined based on the position of each CB group in the M CB groups.

W_j＝X；

if j is M, and S_jZ ≦ Z, indicating that the last CB group of the M CB groups includes a number of bits less than or equal to the maximum number of bits that a CB can include, and thus, the transmitting device or the receiving device may determine:

W_j＝1；

if j is M, and S_jZ indicates that the number of bits included in the last CB group of the M CB groups is greater than the maximum number of bits that a CB can include, and the last CB group of the M CB groups can includeTo include at least two CBs, and thus, the transmitting device or the receiving device may determine:

in summary, in the method 1, the maximum value of the number of CBs included in each CB group is set to X.

And, according to the fact whether TB # a adds check bits, the total bit number B included in TB # a can be determined, that is, TB # a can be written as: b₁，b₂，b₃，…b_A，…，b_BWhere a is the number of bits included in TB # a, and B is the number of bits obtained by adding parity bits to TB # a. And, when TB # a does not need to add a check bit, B ═ a.

Let the maximum number of bits that a CB can include be Z, where Z may be determined according to the data channel coding type specified by the protocol, for example: for Turbo codes, Z is 6144 bits. For LDBC codes, Z may be equal to 6144bits, 4096bits, 8192bits, etc., and descriptions of the same or similar cases are omitted below to avoid redundancy.

In the embodiment of the present invention, the number of bits included in one CB group may be determined according to whether the CB group needs to add a parity bit. That is, the jth CB group in TB # a can be written as: g_j1，g_j2，g_j3，…g_jSjWherein j is 1, 2, … M. Sj is the number of bits included in the jth CB group.

When the CB group is configured to require addition of L parity bits, a value of the L may be a finger specified by a communication system or a communication protocol, and as an example and not by way of limitation, the value of the L may be 2, 4, 8, 16, 24, 32, or 64, and in the following, descriptions of the same or similar cases are omitted to avoid redundancy.

Without loss of generality, let utilize g_j1，g_j2，g_j3，…g_j(Sj-L)The calculated parity bit of length L is h_j1，h_j2，h_j3，…h_jL。

Let the number of check bits each CB comprises be Q.

Case 1

If TB # a needs to add T check bits, and if L check bits need to be added in a CB group, the number M of CB groups that TB # a includes may be determined by the following procedure.

Thereafter, bits in TB # a included in each CB group can be determined

Case 2

If TB # a needs to add T check bits, and if no check bits need to be added in a CB group, the number M of CB groups that TB # a includes may be determined by the following procedure.

Thereafter, bits in TB # a included in each CB group can be determined

Case 3

If TB # a does not require the addition of check bits, and if L check bits need to be added in a CB group, the number M of CB groups that TB # a includes can be determined by the following procedure.

L＝L0；

Thereafter, bits in TB # a included in each CB group can be determined

Case 4

If TB # a does not require the addition of T check bits and if no check bits need to be added in a CB group, the number M of CB groups that TB # a includes can be determined by the following procedure.

Thereafter, bits in TB # a included in each CB group can be determined

Thus, based on the manner 1, the transmitting device can determine the M CB groups that TB # a includes, and the bits in TB # a that each CB group includes.

Mode 2

If the number of CBs into which TB # A can be divided is P, if the TB # A is configured to need to add check bits, and B is less than or equal to Z, P is 1;

if the TB # A is configured without the need to add check bits, then

If TB # A is configured to require the addition of check bits and B > Z, then

Where B is a + T, T is the number of parity bits added in the first transport block TB, T >0, L is the number of parity bits added in each CB group, L ≧ 0, Q is the number of parity bits added in each CB, and Q ≧ 0. Z represents the maximum number of bits included in each coding block CB, X represents the maximum number of CBs included in each CB group, and the value of X may be specified by a communication system or a communication protocol, or may be determined by a network device and issued to a terminal device.

Thus, the transmitting device or the receiving device can determine the maximum number X of CBs that can be included in each CB group specified by, for example, the communication system or the communication protocol, based on the number P of CBs into which TB # a can be divided and the maximum number X of CBs that can be included in each CB group

That is, in the embodiment of the present invention, the sending device and the receiving device may determine, according to the value of M, the number W of CBs included in the CB group j of the M CB groups_j，j∈[1，M]According to the W_jDetermines the number S of bits comprised by the CB group j_j。

In the embodiment of the present invention, since the total number of bits of each CB group is determined according to whether a check bit needs to be added in each CB group, the sending device and the receiving device may determine the number of CB groups included in each TB according to whether a check bit needs to be added in each CB group.

By way of example and not limitation, in embodiments of the present invention, the number S of bits included in CB group j may be determined in the following manner_jAnd the number W of CBs included in the CB group j_j。

That is, if j < M, the transmitting device and the receiving device may determine that: w_j＝X；

If j ═ M, the transmitting device and receiving device may determine: w_j＝P－X×(M－1)；

Further, if j < M, the transmitting device and the receiving device may determine that:

S_j＝W_j×Q+W_j×E₁+L；

if j ═ M, the transmitting device and receiving device may determine:

S_j＝W_j×Q+(W_j－1)×E₁+E₂+L；

wherein if the TB # A is configured to require the addition of check bits and B ≦ Z, then

E₂＝0；

If TB # A is configured to require the addition of check bits and B > Z, then

If the TB # A is configured without the need to add check bits, then

Where B is a + T, T is the number of parity bits added in the first transport block TB, T >0,

Case 5

If T parity bits need to be added in TB # a and if L parity bits need to be added in a CB group, the number M of CB groups that TB # a includes can be determined by the following method and procedure.

Let the total number of CBs included in TB # a be P, and the number of bits included in one CB be E.

The transmitting device may put the E bits of TB # a that are not blocked into the vth CB.

end for

Thereafter, the transmitting device may determine the total number of CB groups W in the total number of CB groups M, CB groups j included in TB # A_jNumber of bits S included in CB group j_j。

The sending device may take W ungrouped CBs to form the jth CB group, and add a check bit with length L behind the CB group j to obtain a bit g in the CB group j_j1，g_j2，g_j3，…g_jSj。

end for

Case 6

If T check bits need to be added in TB # a and if it is not needed to be added in CB groups, the number M of CB groups that TB # a includes can be determined by the following method and procedure.

end for

end for

Case 7

If it is not necessary to add the check bits in TB # a and if it is necessary to add L check bits in the CB group, the number M of CB groups that TB # a includes can be determined by the following method and procedure.

end for

The sending device may fetch W_jThe ungrouped CBs form the jth CB group, and check bits with the length of L are added behind the CB group j to obtain bits g in the CB group j_j1，g_j2，g_j3，…g_jSj。

end for

Case 8

If it is not necessary to add the check bits in TB # a and if it is not necessary to add the check bits in the CB groups, the number M of CB groups that TB # a includes can be determined by the following method and procedure.

end for

Thus, based on the pattern 2, the transmitting device can determine the M CB groups that TB # a includes, and the bits in TB # a that each CB group includes.

That is, in the above mode 1 or mode 2, the sending device may determine that the bit included in the CB group j: g_j1，g_j2，g_j3，…g_jSj。

As described above, the maximum number of bits that each CB can include is Z. And setting the bit number value of the CB as K, wherein K belongs to [ n, Z ], and n is the minimum value of the bit number included by the CB.

In this embodiment of the method, the sending device may determine the bits (or bits) actually included in each CB group included in TB # a based on whether the CB group included in TB # a and TB # a needs to add a check bit. Not in general, let CB in CB group j_rThe bits of (a) are: c_r1，C_r2，…，C_rKrWherein r ∈ [1, W ]_j]，K_rIs CB_rThe number of bits actually included.

Thereafter, the transmitting device may determine the bits in CB group j

As described above, the transmitting device may divide TB # a into M CB groups, and the transmitting device may determine bits included in each CB group.

Also, at S220, the transmitting device may transmit each CB in each CB group to which the TB # a corresponds to the receiving device.

For example, the transmitting device may transmit control information to the receiving device, which may be used to carry communication resources (e.g., time-frequency resources) of the TB # a (or each CB in the TB # a).

Thus, the receiving device can receive the M CB groups (specifically, each CB in the M CB groups) determined by the transmitting device as described above through the communication resource.

By way of example and not limitation, the receiving device may determine the maximum number X of CBs included in each CB group according to the manner described above. And, the receiving device can determine whether TB # a has check bits added thereto according to the manner described above. Also, the receiving device may determine whether each CB group in TB # a is added with a check bit according to the manner described above.

And, the receiving device can demodulate and decode the CBs in each CB group.

For example, if all CBs in a certain CB group are successfully demodulated and decoded, at S230, the receiving device may feed back ACK information for the CB group to the transmitting device.

For another example, if all CBs in a certain CB group fail to demodulate and decode, the receiving device may feed back NAK information for the CB group to the transmitting device at S230.

In addition, in the embodiment of the present invention, the control information includes N control information fields, and the N control information fields may correspond one-to-one to N theoretical CB groups (i.e., N CB groups included in TB # a at most).

And, a control information field i in the N control information fields may be used to indicate whether a theoretical CB group corresponding to the control information field i needs to be transmitted by the network device and received by the terminal device.

Or, a control information field i in the N control information fields may be used to indicate whether a theoretical CB group corresponding to the control information field i needs to be received by the network device and sent by the terminal device.

Wherein i belongs to [1, N ].

It should be understood that the above value range of i is only an exemplary illustration, and the present invention is not limited thereto, for example, the value range of i may also be: i belongs to [0, N-1 ].
