Various embodiments of the present invention will be described below with reference to the accompanying drawings.

 In order to solve the problems in the prior art, an embodiment of the present invention provides an information configuration method, an information processing method, an apparatus, and a communication system, which are configured to indicate multiple transmissions used by a transmitting end and a receiving end by using configured indication information. How is the resource used for the transmission of the transport block (TB) (ie, the data block), so that the receiver determines whether the transport block transmitted on multiple transport resources (or opportunities) belongs to multiple retransmissions of one TB or multiple The transmission of TB, so that when the received data is merged, multiple redundant versions belonging to one TB can be effectively merged.

 The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

 Example 1

1 is a flow chart of an information configuration method according to Embodiment 1 of the present invention. As shown in FIG. 1, the method includes: Step 101: A first device configuration indication information, where the indication information includes a data block corresponding to a transmission resource. Identification information.

 According to the foregoing embodiment, the transmitting end user equipment that performs D2D communication is configured to send a corresponding data block on the transmission resource, so that the receiving end user equipment combines the received data according to the indication information, and the current data is resolved. There are problems in the technology.

 In this embodiment, the transmission resource is multiple, which is also called a transmission opportunity (T0, Transmission

Opportunities ) , if greater than or equal to 2.

 In this embodiment, the identifier information may be a data block identifier, where the data block identifier is a process number of the transport block. In this embodiment, the data block identifier may be a process number of the transport block, and may include, but is not limited to, the following meanings: a process serial number or identifier of a hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request); Or identification; the process ID or ID of the TB transmission.

 In this embodiment, the identification information may be associated with the transmission resource identifier, so that the mapping relationship between the transmission resource identifier and the data block identifier may be obtained.

 In this embodiment, the data block is also referred to as a transmission block (TB).

 In this embodiment, the first device may further configure other information for each transport block, such that the indication information may further include other information corresponding to the transport block, and the other information may include one or more of the following information. : Modulation and coding scheme (MCS) level, new data indication (Li), redundancy version (RV), but not limited to the above information, may also include other information, which will not be described here.

 In this embodiment, transport blocks corresponding to different transmission resources may be the same or different. For example, when the number of transport blocks is less than the number of transmission resources, the transport blocks corresponding to different transmission resources may be the same. For example, the number of transmission resources is 4, when the number of transmission blocks is 1, the one transmission block is mapped to 4 transmission resources, so that the transmission blocks transmitted by different transmission resources are the same; when the number of transmission blocks is 4, The four transport blocks are respectively mapped to four transmission resources, so that the transport blocks transmitted by different transport resources are different. When the number of transport blocks is 2, the two transport blocks are mapped to four transmission resources, such as the first two transmission resources. The first transport block is transmitted, the latter two transport resources transmit the second transport block, or alternately correspond to the first transport block and the second transport block on consecutive transmission resources.

 In this embodiment, in order to save the signaling overhead, some information corresponding to part or all of the transmission resources (transport blocks) may be preset, such as setting the redundancy versions RV and NDI to a fixed value, such that the transmitting end and the receiving end The end user equipment can know the other information in advance, and does not need signaling indication, thereby reducing signaling overhead.

The following is an example of a method of fixing the RV value, but the information is not limited to the RV, and may be other information. For example, the RV corresponding to all or part of the transmission resources may be in a fixed version, such as version RV=0, on the network side. It is pre-agreed with the user side that the value of the RV is not limited to the above value, and may be other fixed values;

 In addition, the value may be set in a preset manner, and the network side and the user side agree to make the RV determined by the network side and the user side according to a predetermined manner, thereby saving signaling overhead.

For example, when different transmission resources correspond to the same transport block, the RB of the first transmission resource corresponding to each TB uses a fixed version, such as RV=0 _;

 For example, take values according to a predetermined order:

 When the transport blocks corresponding to different transmission resources are different, the values may be sequentially taken in a predetermined order. For example, the value of the RV version is 0, 2, 3, 1, and when mapping 4 transport blocks to 4 transmission resources, the value of each transmission resource may be 0, 2, 3, 1 in sequence;

 In the case where different transmission resources correspond to the same transport block, the RV of the first transmission resource corresponding to the same transport block may be used in a fixed version, and the others may be in a predetermined order. For example, when three transport blocks are mapped to four transmission resources, two of the transmission resources correspond to the same transport block, so that the RV of the first transmission resource corresponding to the same transport block can be used in a fixed version, such as RV= 0, the RV of other transmission resources are 0, 2, 3 in order; if 2 TOs are mapped to 4 transmission resources, the RV of the first transmission resource corresponding to the same data block uses a fixed version, such as RV=0 The RV of other transmission resources is taken as 0 and 2 in order. The embodiment is not limited to the above sequence, and other sequences may be used, and details are not described herein again.

 In addition, the RV value may also be configured first, and then indicated by dynamic signaling, such as RV version indication signaling, so that the user equipment obtains the RV.

 In this embodiment, other information corresponding to different transmission resources but the same data block may be the same. For example, one data block is mapped to four transmission resources, and the four transmission resources may have the same MCS level, which further reduces the overhead of signaling.

 In this embodiment, when multiple sets of identification information are configured, multiple sets of mapping relationships may be obtained. In this case, state information corresponding to each set of mapping relationships may also be configured, and the status information is used to indicate corresponding to the transmission resource. Transport block. For example, the status information can be represented by a state of n bits, and n is a positive integer, which can be selected according to actual needs. Hereinafter, T0 and TB are 4, and a 2-bit state is used as an example for explanation.

As shown in Figure 2, the number of bits is 2, corresponding to 4 states, such as "00", "01", "10", "1 1", and the state of each bit indicates a mapping relationship, such as "00" Indicates that 4 TOs correspond to 1 TB I; "01" indicates that 2 TOs correspond to 2 TBs, and the first half TO corresponds to TB1, the second half T0 corresponds to TB2; "10" indicates that 4 T0 corresponds to 3 TBs, The first two TOs correspond to TB1, the third TB corresponds to TB2, and the fourth TB corresponds to TB3; "11" indicates that 4 TOs correspond to 4 TBs, and each TO corresponds to a different transport block, which is TB1, TB2, TB3, and TB4, respectively.

 In this embodiment, the number of the transmission resources may be pre-configured and stored on the network side and the user side device. In addition, the number of transmission resources may also be configured by a network side device, such as a base station, to notify the user equipment by signaling, such as higher layer signaling. For example, TB is a maximum of 1, 2, or a value greater than 2.

 In this embodiment, the transport block may be a data block transmitted on a cellular link between the base station and the user equipment, or on a D2D link; the transport block may also be a scheduling assignment (SA) transmitted on the D2D link. Control information.

 As shown in FIG. 1, the method further includes:

 Step 102: Send the configured indication information to the second device.

 The indication information may be sent by any existing manner, such as by high-level signaling, or by dynamic control signaling, such as downlink control signaling DCI or scheduling allocation SA, or the foregoing two methods. Combination of.

 In this embodiment, step 102 is an optional step. After the network side base station configures the foregoing indication information, the indication information may be stored on the network side and the user side respectively, and step 102 is not performed.

 In this embodiment, the first device may be a network side device, such as a base station, by using the indication information to indicate a transport block (TB) corresponding to multiple transmission resources. In this case, the second device can be a user device. In step 102, the first device may notify the second device of the indication information by using the DCI, but is not limited thereto, and may also notify by other existing or newly created messages.

 In this embodiment, the first device may also be a sender device that performs D2D discovery/communication. In this case, the second device may be a receiving end user device for D2D discovery/communication. In step 102, the first device may notify the second device by using a scheduling assignment (SA), but is not limited thereto, and may also notify by other existing or newly created messages. In this case, the method may further include: transmitting, according to the configured indication information, a corresponding data block to the third device on each of the transmission resources. The third device is a recipient user device for D2D communication.

 It can be seen from the above that how the multiple transmission resources used on the D2D link are used for the transmission of the transport block (TB), that is, the configuration of the identifier information can be implemented by the network side base station or by the transmitting user equipment of the D2D communication.

 The following is an example of the configuration of the indication information:

Example 1, the configuration instructions, as shown in Table 1: Table 1

As shown in Table 1, multiple transmission resources are identified from #1 to #n _; for each transmission resource, the process number of the corresponding transport block (TB) is configured, such as #i, #j, #m, # n, to #k. The above i, j, n, m and k are all positive integers.

 In this embodiment, the number of the transmission resources may be reserved, or the number of the transmission resources is configured for the transmitting end user equipment and the receiving end user equipment of the D2D link by using the higher layer signaling, and then the transmission resource corresponds to the transmission block. The transmission resource is associated with the transport block by a fixed relationship as shown in Table 1.

 In addition, the corresponding relationship between the transmission resource and the transport block may be configured semi-statically, and the user equipment is notified by high layer signaling.

 Example 2 is described by taking four transmission resources as an example, where the transmission resource identifier #i is represented as T0#i.

Table 2-1 (4T0 corresponds to 4 TB)

 As shown in Table 2-1, four TBs are mapped to different TOs. For example, configurable T0#1 corresponds to the initial transmission of TB#1, T0#2 corresponds to the initial transmission of ΤΒ#2, Τ0#3 corresponds to the initial transmission of ΤΒ#3, and TOM corresponds to the initial transmission of TBM.

Table 2-2 (4T0 corresponds to 3 TB)

 As shown in Table 2-2, three TBs are mapped to four TOs. For example, configurable T0#1 corresponds to the initial transmission of ΤΒ#1.

Τ0#2 corresponds to the retransmission of ΤΒ#1, Τ0#3 corresponds to the initial transmission of ΤΒ#2, and TOM corresponds to the initial transmission of TB#3.

Table 2-3 (4T0 corresponds to 2 TB)

As shown in Table 2-3, two TBs are mapped to four TOs. For example, configurable T0#1 corresponds to 初#1's initial transmission, Τ0#2 corresponds to ΤΒ#1 retransmission, Τ0#3 corresponds to ΤΒ# The first pass of 2, TOM corresponds to the retransmission of TB#2. Table 2-4 (4T0 corresponds to 1 TB)

 As shown in Table 2-4, one ΤΒ maps to four TOs. For example, configurable T0#1 corresponds to 初#1's initial transmission, Τ0#2 corresponds to ΤΒ#1 retransmission, Τ0#3 corresponds to ΤΒ# 1 retransmission, Τ0#4 corresponds to 重#1 retransmission.

 In addition, other information such as (MCS) level, new data indication (Li), redundancy version (RV), etc. can be configured, as shown in Table 1.

 In this embodiment, the foregoing correspondence may be semi-statically configured, that is, periodically configured.

 Example 3, based on the configuration of Table 1, in order to save signaling overhead, the same information may be configured for different transmission resources, for example, other information corresponding to different transmission resources but the same data block may be the same, such that part or all of the transmission resources correspond to The signaling may be reused, or may be pre-agreed between the network side and the user equipment side, or between the user equipment side using a fixed rule, such as a preset. The following examples are given:

 Table 3-1 shows the case where three transport blocks correspond to four transmission resources.

 Table 3-1 (3TBs->4T0s: 1, 2, 3, 3)

 As shown in Table 3-1, the transmissions (TB#m) corresponding to the transmission resource identifiers #3 and #4 are the same, and the configured MCSs are the same, that is, MCS#m, which saves signaling overhead.

 Alternatively, in order to reduce the signaling overhead, a fixed rule may be used, such as a pre-determined manner between the network side and the user side, or the user side device, such as the default by both parties, as shown in Table 3-2.

Table 3- 2

 The above two methods of reducing signaling overhead can be used simultaneously or separately.

 Table 4-1 shows the case where two transport blocks correspond to four transmission resources.

As shown in Table 4-1, transport block #i corresponds to transport resource identifiers #1 and #2, using the same MCS#i, transport block #m corresponding to transport resource identifiers #3 and #4, using the same MCS#m, Signaling overhead can be saved. Similarly, in order to reduce signaling overhead, fixed rules can also be used, as shown in Table 4-2. Table 4-1 (2TBs->4T0s: l, 1, 2, 2)

 The above two methods of reducing signaling overhead can be used simultaneously or separately.

 Table 5-1 shows the case where one transport block corresponds to four transmission resources.

 Table 5-1 ( lTBs->4T0s : l, 1, 1, 1 )

 As shown in Table 5-1, one TB corresponds to the transmission resource identifiers #1 to #4, and the same MCS#m is used, which saves signaling overhead. Similarly, in order to reduce signaling overhead, fixed rules can also be used, as shown in Table 6-2.

Table 5-2

 The above two methods of reducing signaling overhead can be used simultaneously or separately.

 In the present embodiment, the above table wide table 5 exemplifies only the manner in which the information is arranged. However, the present invention is not limited to the above-described modes, and other modes, or a combination of the above various modes, may be used.

 In this embodiment, in step 102, the information of Table 1 to Table 5 above may be sent by the base station through any existing message or a new message. In this way, the above information is also available on the user equipment side. Alternatively, the foregoing information may also be sent through dynamic control information, such as DCI or through SA. The signaling structures in Table 1 and Table 2 may be generally referred to as a signaling structure in a cascading manner, and a signaling structure in Table 3 to Table 5. It can often be referred to as a compact signaling structure.

In the present embodiment, the foregoing Tables 1 to 5 illustrate the method of the configuration information, but the embodiment of the present invention is not limited to the above configuration, and is not enumerated here. Example 4: After multiple sets of identification information are configured to obtain mappings between multiple sets of transmission resource identifiers and transport block identifiers, status information may also be configured to indicate each set of mapping relationships.

 For example, seven sets of indication information are configured as shown in Table 1, Table 2 - Wide Table 2-4, Table 3-1, Table 4-1, and Table 5-1. For each group of indication information, an indication indicating each group can also be configured. The status information of the information, such as a state of 3 bits, respectively represents each set of indication information.

 As shown in Fig. 2, the state information is represented by a state of 2 bits.

 In example 5, when the system supports one or two TB transmissions, the correspondence between the transmission resources TO and TB can be fixed by the standard.

 For example: When using 1 TB, 1 TB is mapped to all TOs, as shown in Table 6-1.

 Table 6-1 (4T0 corresponds to 1 TB)

 When 2 TBs are used, TBI and TB2 can be alternately transmitted on consecutive TOs, as shown in Table 6-2; considering the delay of reducing TB decoding, another solution is to transmit TBI on the first half of TO first. Data, the data of TB2 is transmitted on the post-half TO, as shown in Table 6-3.

除了配置上述指示信息外， 还可配置其他信息如 MCS等级、 RV等信息。 但为了 减少信令开销， 部分信息如 RV可采用固定版本， 如在上述全部或部分 TO上的 RV版 本采用固定版本， 如 RV=0_; 或者， 还可按照预定的顺序取值， Table 6-2 (4T0 corresponds to 2 TB)

In addition to the above instructions, other information such as MCS level, RV, etc. can be configured. However, in order to reduce the signaling overhead, some information such as RV may adopt a fixed version, such as a fixed version of the RV version on all or part of the above TO, such as RV=0 _; or, may also take values in a predetermined order,

 In Table 6-1, in the order of 0-2-3-1, the first TO value loop 0, the second TO value loop 2, the third TO value RV#3, the fourth TO take Value RV#1 ; or,

 In Table 6-2, the RV on Τ0#2 corresponding to Τ0#1, ΤΒ#2 corresponding to TB#1 is set to a fixed value, such as RV#0, and the RV on other transmission resources is 0-2-. The order of 3-1 is sequentially taken as RV#0.

In this embodiment, the RV version of the first TO is related to the current subframe number, and therefore, can also be determined as follows: RV=cei l ing (3/2*k) modulo 4, where k is a subframe number. Where cei l ing indicates Round up, modulo means value.

 In this way, by setting the RV in advance or setting the manner of determining the RV in advance, the network side and the user side device can be made aware of the RV corresponding to each transmission resource (transport block).

 In addition, the value of the RV can also be indicated by dynamic signaling, such as RV version indication information.

 Example 6, when the maximum number of TBs supported by the system for multiple transmission resources of the D2D is 2, when the indication information of the configuration is dynamically indicated, the dynamic signaling part, such as the control signaling in the DCI or the SA, may reuse the multi-codeword. A partial indication field of the dynamic signaling format, such as each TB in DCI format 4 indicates domain MCS information and NDI information.

 For other information, such as resource allocation information, two TBs can be shared.

 The resource locations of the respective TOs may be located in the same resource unit, and the resource units may include multiple PRBs, and the used transmission resource location information is obtained through resource configuration signaling and an implicit relationship.

 Example 7, the first device can configure the number of TBs, which is indicated by dynamic signaling.

 When the maximum number of TBs supported on the D2D link is 2:

 For example, the indication mode of the display: 1 or 2 TB can be indicated by 1 bit. If the bit is "0", the number of TBs is 1; when "1", the number of TBs is 2; or,

 For example, the implicit indication mode is implicitly indicated by configuring the second TB to be a fixed configuration, such as by using a preset MCS level. For example, one of the following two methods is selected according to the actual number of scheduled PRBs. : MCS is 0, the number of PRBs is greater than 1 (used when the actual number of scheduled PRBs is greater than 1); or, MCS is 28, and the number of PRBs is 1 (used when the actual number of scheduled PRBs is equal to 1). The above MCS levels 0, 28 may also be preset to other values, and the above is only an embodiment of the present invention.

 When the system does not limit the maximum number of TBs supported by multiple TOs of D2D, such as D2D link support is more than

For 2 TB, the first device can semi-statically configure TB or dynamically configure the number of TBs. The first device first uses the high-level information to configure the number of supported TBs, and then directly cascades the control information of the multiple TBs, as shown in the above table 5 .

 Example 8, in the above example 7, using the configuration of the second TB, the MCS level can also be used to implicitly indicate whether the TB is available or disabled, or the first TB copy (duplication) ), or RV version, this way can be extended for more than 2 TB cases. At this time, the corresponding MCS of the nth TB may be configured to be one or more specific MCS levels to indicate that the nth TB is a disable or a duplicate or a duplicate of the first TB, or an RV version, Where n>=2.

Increase flexibility through the above implicit indications. The amount of resources allocated may be more than the required amount, so the ministry The TB location of the minute can be set to be unavailable. on the other hand. If multiple user equipments are allocated the same resources for transmission, interference can be avoided by this mechanism.

 The following describes the scenario of the D2D broadcast communication mode as an example. However, the present invention is not limited to this scenario and is used in other scenarios involving broadcast communication.

 In the D2D broadcast communication mode, the probability that the high-level MCS is used is relatively low, so it is particularly possible to use some high-level MCS to implicitly characterize whether the TB is capable or disabled, or the first TB. Duplicate (dupl ication), or RV version.

 For example, the MCS is 28, the number of PRBs is greater than 1 (used when the actual number of scheduled PRBs is greater than 1) or the MCS is 27, and the number of PRBs is 1 (used when the actual number of scheduled PRBs is equal to 1), indicating whether the TB is capable or disabled. , or the first TB copy (dupl ication), or RV version.

 For example, if the MCS is 28, it means that the TB is able or disable, or the first TB copy (dupl ication), or the RV version.

 For example, the MCS is 29, 30 or 31, which means that the TB is disable, or the first TB copy (dupl ication), or the RV version.

 The above MCS level is only an embodiment of the present invention, but is not limited to the above values. In addition, you can also indicate this by configuring additional information.

 Example 9. In this embodiment, part of the bits of the MCS may also be used as part of the L1 data reception filter identification (ID). For example, the L1 data reception filter ID requires X bits, x may be equal to 8 or 16, and several bits in the MCS field may be used as some of the X bits.

 Example 10 In this embodiment, in order to further reduce signaling overhead, part of the MCS field can also be used for open loop or closed loop power control indication.

 For example, the open loop power control includes parameters, which are used to determine the service characteristics or channel characteristics of the user equipment, or the service priority or UE priority, used by the user equipment to calculate the transmit power. Level related parameters. The value of these parameters can be determined by one or several bits in the MCS field.

 According to the foregoing embodiment, the first device configuration indication information is used to enable the user equipment to perform data transmission or merging according to the indication information. In addition, the signaling corresponding to part or all of the transmission resources may be reused or the manner of setting in advance may be used. Reduce the overhead of signaling.

Example 2 3 is a flow chart of an information processing method according to Embodiment 2 of the present invention. As shown in FIG. 2, the method includes: Step 301: The second device sends corresponding data to a third device on each transmission resource according to the obtained indication information. The indication information includes an identifier of a data block corresponding to the transmission resource. information;

 It can be seen that, after the second device obtains the indication information, the transmission of the transport block can be performed according to the correspondence between the transmission resource and the transport block indicated by the indication information.

 In this embodiment, when the first device is a network side base station, that is, a mode of using the transmission resource of the D2D communication by the base station, the second device may be a user equipment that receives the indication information configured by the base station, and is also performed by the D2D. The transmitting end user equipment in the communicating user equipment, denoted here as DUE1; the third equipment is the receiving end user equipment in the user equipment performing D2D communication, here denotes DUE2.

 In this embodiment, the configuration of the indication information is as described in Embodiment 1, and the content thereof is incorporated herein, and details are not described herein again.

 In addition, when the first device configures other information corresponding to the transmission resource (transport block), the second device may also obtain the other information, such as a modulation and coding scheme (MCS) level, a new data indication (Li), and redundancy. Version (RV), etc., as described in Table 5. In this way, the second device can transmit data according to the location of the configured video resource and the transport block transmitted on each transmission resource.

 In this embodiment, as shown in FIG. 2, the method may further include:

 Step 302: Receive the indication information sent by the first device.
