Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

The terms "first," "second," and the like in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Further, the use of "and/or" in this application means that at least one of the connected objects, e.g., a and/or B and/or C, means that 7 cases are included that include a alone, B alone, C alone, and both a and B, B and C, both a and C, and A, B and C.

Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a sending terminal 11, a network side device 12, and a receiving terminal 13.

The transmitting terminal 11 and the network side device 12 can communicate with each other, and the transmitting terminal 11 and the receiving terminal 13 can communicate with each other. In practical applications, the terminals and the network side device may communicate with each other through a Uu link, and the terminals may communicate with each other directly through a Sidelink (or called as a Sidelink, a side link, or the like, a Sidelink, SL) link. In one implementation, as shown in fig. 1, the transmitting terminal 11 and the network side device 12 may communicate through a Long Term Evolution (LTE) Uu link, and the transmitting terminal 11 and the receiving terminal 13 may communicate through a New Radio (NR) Sidelink link, but it should be understood that fig. 1 is only an example, and therefore does not limit a specific expression form of the communication link.

In this embodiment of the present invention, a terminal may also be referred to as User Equipment (UE), and when the implementation is specific, the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal is not limited in the embodiment of the present invention.

The network side device 12 may be a base station, a relay, an access point, or the like, and the embodiment of the present invention does not limit the specific type of the network side device 12.

For convenience of understanding, some contents related to the embodiments of the present invention are explained below:

1. sidelink

The LTE system may support Sidelink for direct data transmission between terminals without passing through a network side device.

The design of LTE sildelink is suitable for specific public safety affairs (emergency communication in disaster places such as fire places or earthquakes) or Vehicle to internet (V2X) communication, etc. The internet of vehicles communication includes various services, such as: basic security class communication, advanced (automated) driving, formation, sensor extension, etc. Since LTE Sidelink only supports broadcast communication, LTE Sidelink is mainly used for basic security-type communication, and the fifth Generation (5-th-Generation, 5G) NR system can be used for an operating frequency band above 6GHz (gigahertz) that is not supported by LTE, supporting a larger operating bandwidth, so that other advanced V2X services with strict Quality of Service (QoS) requirements in terms of latency, reliability, etc. can be supported by NR Sidelink.

2. Sidelink transmission format

The current Sidelink transmission mainly comprises Broadcast (Broadcast), multicast (Groupcast) and Unicast (Unicast) transmission forms.

Unicast, as the name implies, is a One-to-One (One to One) transmission. Both multicast and broadcast are One-to-Many (One to man) transmissions, but broadcast does not have the concept that UEs belong to the same group.

Currently, the unicast and multicast communication of sildelink supports a Hybrid Automatic Repeat Request (HARQ) feedback mechanism at the physical layer.

3. Resource allocation patterns

The resource allocation pattern of sildelink may include the following two categories:

1) Mode (Mode) 1: a Base Station (BS) schedules SL resources (BS schedules SL resources(s) to used by UEs for SL transmission (s)) used by UEs, and it can be seen that in this mode, a network side device (e.g. a Base Station) controls and allocates resources for each UE, so this mode may also be referred to as a Base Station scheduling mode.

2) Mode 2: the UE determines (i.e., the BS does not schedule) SL transmission resources (UE priorities, i.e., SL transmission resources with SL resources configured by the BS/Network (Network) or preconfigured SL resources among SL resources. It can be seen that in this mode, resources are autonomously selected by each UE, and thus, this mode may also be referred to as a UE autonomous mode.

4. Periodic resource allocation

The NR Uu interface supports two types of periodic resource allocation: a configuration authorization Type (Configured Grant Type) 1 and a Configured Grant Type2. The two configurations are different in that: configured and activated by Radio Resource Control (RRC) signaling, all Resource locations are Configured by RRC signaling, while Configured Grant Type2 is an RRC Configured time domain location, and Layer1 (Layer 1, L1) signaling is activated and indicates specific resources. The two configuration modes have the common point that only the initial transmission of the data uses periodic resources, and the retransmission of the data uses dynamically scheduled resources, and the method can well ensure higher resource utilization rate in consideration of lower retransmission probability.

In a scenario of V2X cross Radio Access Technology (RAT) operation, as shown in fig. 1, a network side device and a transmitting terminal communicate with each other through an LTE Uu interface, and the transmitting terminal and a receiving terminal communicate with each other through an NR Sidelink interface, and in this scenario, dynamic scheduling of NR resources using an LTE Physical Downlink Control Channel (PDCCH) has complexity in design and extra workload of a standard, and thus needs to be avoided as much as possible. Therefore, in order to avoid dynamic resource scheduling of retransmission performed across RATs and enable smooth retransmission of data, the embodiment of the present invention provides a new resource allocation method.

The following describes examples of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of a resource allocation method according to an embodiment of the present invention. The resource allocation method shown in fig. 2 is applied to a sending terminal, and as shown in fig. 2, the resource allocation method may include the following steps:

step 201, receiving first configuration information sent by a network side device, where the first configuration information is used to configure a first periodic resource, the first periodic resource is used for first transmission of first data, and the first transmission is retransmission or repeated transmission.

In practical applications, the first configuration information may be transmitted through RRC signaling, but is not limited thereto. The first data may include one or more data blocks.

In a specific implementation, the first configuration information may include at least one of: and configuring the time domain position and the frequency domain position of the periodic resource and the periodic parameter of the periodic resource to configure the first periodic resource.

In one embodiment, the first configuration resource may be used only for retransmission or repeated transmission; in another embodiment, the first configuration resource may be used not only for retransmission or repeated transmission, but also for initial transmission. For convenience of understanding, each embodiment will be specifically described below.

Implementation mode one

Optionally, the first periodic resource is further used for initial transmission of the first data.

As can be seen, in this embodiment, the first periodic resource may be used not only for retransmission or repeated transmission, but also for initial transmission. That is, the first transmission and the initial transmission use one periodic resource. Thus, the first transmission and the initial transmission can multiplex the first periodic resource, and the resource utilization rate is high.

In implementation, when configuring the periodic resource for initial transmission, the network side device may allocate more resources for the periodic resource for the first transmission on the basis of the original service periodic transmission requirement, in consideration of the first transmission that may occur, so that the periodic resource may be used for the initial transmission and the first transmission.

In an implementation manner, the network side device may configure the first periodic resource based on a service arrival period, and specifically, may configure the first periodic resource with a period smaller than the service arrival period, so that the first periodic resource may be used for both initial transmission of data and first transmission of data. Illustratively, when the period of the service arrival is 20 milliseconds (ms), the network side device may allocate, through RRC signaling, a first periodic resource with a period less than 20ms, for example, a period of 10ms,5ms, or even less, to the transmitting terminal, so that a part of the allocated resource is used for initial transmission of data, and another part is used for retransmission of data.

In another implementation, in a case that a service arrives aperiodically, in order to guarantee a certain QoS requirement for data transmission (for example, maximum transmission delay or block error rate), the network side may directly allocate a periodic resource of a certain period to the sending terminal, where on the periodic resource, the sending terminal may perform initial transmission or first transmission, but a certain resource is specifically used for initial transmission or first transmission, and may be determined according to actual needs.

It should be noted that, in the embodiment of the present invention, the number of the first cycle resources may be greater than or equal to 1. For example, in a case that a service combination or QoS requirement of a sending terminal is complex, a network side device may configure a plurality of first periodic resources for the sending terminal; of course, the network side device may also configure a plurality of first periodic resources for the sending terminal according to the state of its own resources.

In case the number of first periodic resources is larger than 1, different first periodic resources may have different period sizes, resource locations, period offsets, resource sizes, modulation coding formats, numerology, etc. It should be understood that different periodic resource configurations may be constructed as long as there is a parameter inconsistency. The first plurality of periodic resources may be configured by RRC signaling, and the initial transmission and the first transmission may be selected from the resources as needed.

After receiving the first configuration information, the sending terminal may determine that the resource of the first periodic resource is freely usable by itself, and thus may perform the initial transmission and the first transmission of data on the first periodic resource.

Optionally, after receiving the first configuration information sent by the network side device, the method further includes:

performing initial transmission of the first data by using the first periodic resource;

and under the condition of first transmission demand, utilizing the remaining available resources in the first periodic resources to perform first transmission of the first data.

In specific implementation, when receiving a Negative Acknowledgement (NACK) corresponding to the first data fed back by the sending terminal, it may be determined that the sending terminal has a retransmission requirement; and under the condition that the first periodic resource is used for initial transmission and first transmission of a first service and the first service has higher requirements on time delay and block error rate, determining that the sending terminal has a repeated transmission requirement. Specifically, the target service may require that the first transmission delay is smaller than a first value, and the required block error rate is smaller than a second value, where the first value and the second value may be flexibly set according to actual requirements, and are not limited herein.

In addition, in this embodiment, when the first data includes N data blocks, N is an integer greater than 1, and the transmitting terminal can transmit data in at least the following two ways.

In the first mode, after the transmission of the ith to-be-transmitted data block is successfully completed, the initial transmission of the (i + 1) th to-be-transmitted data block is carried out.

Wherein, the successful completion of the transmission of the ith to-be-transmitted data block represents that: and the sending terminal receives a positive Acknowledgement (ACK) which is fed back by the receiving terminal and is relative to the ith pending data block. Therefore, it can be understood that, if the sending terminal does not receive the acknowledgement information of the ith to-be-transmitted data block fed back by the receiving terminal or receives the NACK of the ith to-be-transmitted data block fed back by the receiving terminal, it may be determined that the transmission of the ith to-be-transmitted data block in the current transmission fails, that is, the transmission of the ith to-be-transmitted data block is not completed successfully. i is a positive integer less than N.

For ease of understanding, examples are illustrated below:

suppose that the N data blocks include data block 1, data block 2, and data block 3, and data block 1 is the 1 st data block to be transmitted, data block 2 is the 2 nd data block to be transmitted, and data block 3 is the 3 rd data block to be transmitted.

Then, as shown in fig. 3a, the transmission sequence of the N data blocks in the front-to-back direction in the time domain is: initial transmission of data block 1, initial transmission of data block 2, retransmission of data block 2, initial transmission of data block 3, and so on.

Therefore, in this way, the initial transmission of the next data block to be transmitted is not allowed to be started until the current data block to be transmitted is unsuccessfully transmitted.

In a second mode, after the transmission of the ith data block to be transmitted is completed, the transmission of a first data block is performed, where the first data block is: the (i + 1) th data block to be transmitted or the data block with the first transmission requirement.

Different from the first method, in this method, after the transmission of the ith to-be-transmitted data block is completed, the transmission result is not concerned.

In specific implementation, if the data block with the first transmission requirement is not detected after the transmission of the ith to-be-transmitted data block is completed, the initial transmission of the (i + 1) th to-be-transmitted data block can be performed after the transmission of the ith to-be-transmitted data block is completed.

If the data block with the first transmission requirement is detected after the transmission of the ith to-be-transmitted data block is completed, the first transmission of the data block with the first transmission requirement can be performed after the transmission of the ith to-be-transmitted data block is completed.

For ease of understanding, examples are illustrated below:

suppose that the N data blocks include data block 1, data block 2, data block 3, and data block 4, and data block 1 is the 1 st data block to be transmitted, data block 2 is the 2 nd data block to be transmitted, data block 3 is the 3 rd data block to be transmitted, and data block 4 is the 4 th data block to be transmitted. Data block 1, data block 3 and data block 4 do not have first transmission demand, and data block 2 has the time of first transmission demand after carrying out the initial transmission of data block 3, before carrying out the initial transmission of data block 4, if: after the initial transmission of the data block 2 is completed, the sending terminal does not receive the feedback information corresponding to the data block 2, so that the initial transmission of the data block 3 can be performed; during or after the transmission of the data block 3, NACK corresponding to the data block 2 is received, and at this time, the data block 2 has a retransmission requirement, so that the retransmission of the data block 2 can be performed after the initial transmission of the data block 3 is completed.

Therefore, as shown in fig. 3b, the transmission sequence of the N data blocks in the front-to-back direction in the time domain is: initial transmission of data block 1, initial transmission of data block 2, initial transmission of data block 3, retransmission of data block 2, initial transmission of data block 4, and so on.

Further, in practical applications, optionally, the method further includes:

under the condition that a second data block in the first data is to be transmitted, selecting a first resource in the first periodic resource for initial transmission of the second data block, wherein the first resource is a resource which meets the transmission condition of the second data block in a time domain in the current remaining available resources;

and under the condition that the second data block has a first transmission requirement, selecting a second resource in the first periodic resource to perform first transmission of the second data block, wherein the second resource is a resource which meets the transmission condition of the second data block in a first time domain in the current remaining available resources.

It should be understood that the second data block may be any data block in the first data.

In practical application, after receiving the first periodic resource, the terminal can know the resource that can be used freely, so that when the UE has a data block to transmit, the UE can select the closest resource in the time domain that meets the transmission condition of the data block for transmission.

The resource size of the resource which meets the transmission condition of the data block can meet the transmission requirement of the data block, and the situation that the transmission of the data block cannot be realized due to too small resource cannot be caused.

Generally, when a new data packet arrives, the transmitting terminal may select the latest qualified resource for transmission according to the data characteristics (such as the data size and the modulation and coding scheme of the data), and if the receiving terminal feeds back ACK, the primary data is successfully ended. If the receiving terminal feeds back NACK, the transmitting terminal needs to retransmit the data packet, selects the latest resource meeting the retransmission condition for retransmission, and feeds back ACK if the receiving terminal receives the data packet correctly or decodes the data packet correctly with the previous combination, and also marks that one-time data transmission is successfully finished.

In this embodiment, since the first periodic resource may be used for the initial transmission and the first transmission of the first data, and the first data may include a plurality of data blocks, when the sending terminal performs the transmission of the data blocks, it needs to take necessary measures, so that the receiving terminal can identify and combine the initial transmission and the first transmission of the same data block.

On one hand, in order to enable the receiving terminal to recognize the initial transmission data and the first transmission data, the sending terminal may carry first identification information in the transmitted data, where the first identification information is used to identify a data transmission type.

Specifically, the data transmission types may include initial transmission data, retransmission data, and repeated transmission data, and it should be understood that, for the first identification information identifying different data transmission types, it has different expressions, such as: for the first identification information identifying the initial transmission data, the first identification information can be expressed as an initial transmission identification; for the first identification information identifying the retransmission data, it may be expressed as a retransmission identification.

In practical applications, the first identification information may be represented as: new Data Indication (NDI) or Redundancy Version (RV) Version number. In addition, the first identification information may be predefined by a network-side device configuration or a protocol.

In specific implementation, the initial transmission/retransmission identifier can be agreed. If the data is the initial transmission data, the sending terminal may use the parameter of the initial transmission data and carry the relevant identifier of the initial transmission data, such as the NDI or RV version number, to indicate that the data is the initial transmission data. If the data is the retransmission data, the UE may use the parameter of the retransmission data and carry the retransmission identifier associated with the retransmission data, indicating that the data is the retransmission data.

On the other hand, in order that the receiving terminal can recognize the same data, the transmitting terminal can perform transmission of the data in the following manner.

In the first method, the sending terminal may carry an HARQ Process identifier (Process ID) in each data block transmitted, and the same data block carries the same HARQ Process ID. The HARQ Process ID can be understood as a data identification.

And in addition, the transmitting terminal can perform initial transmission of the (i + 1) th to-be-transmitted data block after the transmission of the (i) th to-be-transmitted data block is successfully completed.

Exemplarily, after the initial transmission of the data block a carrying the HARQ Process ID 0 fails, the receiving terminal returns NACK, and then the retransmitted data block received by the receiving terminal is always the data block a, even if the retransmitted data block does not carry the HARQ Process ID 0.

In addition, after completing the initial transmission of a certain data block, if the data block has a first transmission requirement, the sending terminal may perform the first transmission of the data block after a Round Trip Time (RTT) connected to the initial transmission of the data block by one connection. The RTT is a difference between a data transmission time and a time when the acknowledgment is received.

For example, if the HARQ RTT is M milliseconds, the receiving terminal may determine that the received initial transmission data block and the retransmission data block after the initial transmission interval of M milliseconds belong to the same Process, that is, the same data is obtained.

It should be noted that, when the number of the first periodic resources is greater than 1, generally, the initial transmission and the retransmission of the same data block are preferably generated in the same periodic resource, but may also be generated in different periodic resources, and if the retransmission of different periodic resources occurs, an explicit HARQ Process ID is needed to associate the relationship between the initial transmission and the retransmission, which indicates that the data block is the same data block, and then the retransmission and the combining are performed.

Further, the sending terminal may also carry a Destination ID in the sent data, which is used to indicate a receiving terminal that receives the data, and only the receiving terminal associated with the Destination ID will decode the data. The Destination ID can be understood as a terminal identifier.

Therefore, the receiving terminal can combine the initial transmission and the retransmission of the same block data according to the received initial transmission and retransmission identification and by combining the Destination ID and the HARQ Process ID.

Second embodiment

Optionally, in a case that the first periodic resource is used for retransmission of the first data, the method further includes:

and receiving second configuration information, where the second configuration information is used to configure a second periodic resource, and the second periodic resource is used for initial transmission of the first data.

As can be seen, in this embodiment, the first periodic resource is used for retransmission or repeated transmission, and the second periodic resource is used for initial transmission. That is, the first transmission and the initial transmission each use independent periodic resources.

In a specific implementation, the configuration of the second periodic resource may adopt a conventional configuration of a Configured Grant Type1 of the periodic resource.

The configuration of the first periodic resource may be as follows:

the first mode is to multiplex the configuration in a mode similar to the configured grant type1, but the indication to be displayed is a retransmission resource, and the retransmission resource and the initial transmission resource are in a binding relationship, for example, the association with the initial transmission can be indicated by the Process information, which has the advantage that different parameters and resource positions can be configured independently.

In a second mode, the retransmission resource may be configured in a differentiated incremental manner based on the initial transmission resource, and only parameters different from the initial transmission resource need to be configured, for example:

the offset in the Time domain, generally speaking, RTT of HARQ Transmission can be estimated, and retransmission can be performed after an initial Transmission position is transmitted to an Interval of N Transmission Time Intervals (TTI), so that a retransmission position can be determined according to the Interval RTT, generally speaking, the Time domain needs an Interval, and the frequency domain position can multiplex initial Transmission or configure different resources, depending on implementation of a base station;

retransmission-specific transmission parameters, such as power control parameters, etc.

After receiving the first configuration information, the sending terminal may determine that the resources of the first periodic resource and the second periodic resource are freely usable by itself, and therefore, may perform initial transmission of data on the second periodic resource and perform first transmission of data on the first periodic resource.

Optionally, the method further includes:

performing initial transmission of the first data by using the second periodic resource;

and under the condition of a first transmission requirement, utilizing the first periodic resource to perform first transmission of the first data.

For determining the mode with the first transmission requirement, reference may be specifically made to the description of the first embodiment, and details are not described here.

In this embodiment, since both the first periodic resource and the second periodic resource can be used for transmitting the first data, it can be understood that there is a corresponding relationship between the first periodic resource and the second periodic resource.

In specific implementation, optionally, the first periodic resource and the second periodic resource satisfy any one of the following correspondence relationships:

a one-to-one correspondence;

a one-to-many correspondence;

many-to-one correspondence.

It should be noted that, in the embodiment of the present invention, the first periodic resource and the second periodic resource that have a corresponding relationship may be regarded as a set of periodic resources.

For example, if the network-side device is configured with a first periodic resource a and a second periodic resource a corresponding to the first periodic resource a, it may be understood that: the network side device is configured with a set of periodic resources, and the set of resources includes a first periodic resource (i.e., a first periodic resource a) and a second periodic resource (i.e., a second periodic resource a).

If the network side device is configured with: a first periodic resource a, a second periodic resource a corresponding to the first periodic resource a; first periodic resource b, second periodic resource b corresponding to first periodic resource b, and second periodic resource c corresponding to first periodic resource b, can be understood as: the network side device is configured with two sets of periodic resources, one set of resources includes a first periodic resource (i.e., a first periodic resource a) and a second periodic resource (i.e., a second periodic resource a), and the other set of resources includes a first periodic resource (i.e., a first periodic resource b) and two second periodic resources (i.e., a second periodic resource b and a second periodic resource c).

The following describes each scenario in which the first periodic resource and the second periodic resource satisfy different correspondence relationships.

Scene one, the first periodic resource and the second periodic resource satisfy a one-to-one correspondence.

In this scenario, the transmitting terminal may make multiple first transmissions in the first periodic resource.

And in a second scenario, the first periodic resource and the second periodic resource meet a many-to-one correspondence relationship.

In this scenario, one second periodic resource corresponds to a plurality of first periodic resources.

In specific implementation, the network side device may consider multiple retransmissions of the HARQ, and may configure multiple first retransmission resources for the sending terminal, where a specific number of the first retransmission resources may depend on service requirements and network implementation.

Optionally, each of the first periodic resources is used for one first transmission of the first data.

Further, the performing, by using the first periodic resource, the first transmission of the first data in the case of a first transmission requirement includes:

and under the condition that a jth first transmission demand exists, carrying out jth first transmission on the first data by using a target first periodic resource, wherein the target first periodic resource is used for the jth first transmission of the first data, j is a positive integer smaller than or equal to M, and M is the number of the first periodic resources.

In a specific implementation, the network side device may pre-configure an order of each first periodic resource for the first transmission of the first data. In this way, the sending terminal may determine, from a plurality of first periodic resources, the target first periodic resource for the jth first transmission of the first data under the condition that there is a jth first transmission demand, and perform the jth first transmission of the first data by using the target first periodic resource, where j is a positive integer less than or equal to M, and M is the number of the first periodic resources.

For ease of understanding, the examples are illustrated below:

it is assumed that one second periodic resource corresponds to two first periodic resources, namely a first periodic resource a and a second periodic resource b, where the first periodic resource a is used for a first transmission and the first periodic resource b is used for a second transmission. The period of the first periodic resource and the second periodic resource is equal, e.g. 20ms. The first retransmission resource a occurs 5ms after the second periodic resource (assuming HARQ RTT is 5 ms), and the first retransmission resource b occurs 5ms after the first retransmission resource a.

The first data comprises a data block 1 and a data block 2, the data block 1 has a first transmission requirement, and the data block 2 has no first transmission requirement.

Then, as shown in fig. 3c, in each 20ms traffic period, the initial transmission of data block 1 and data block 2 is performed on the second periodic resource first. In case the ACK was not successfully received for the initial transmission of data block 1, the first retransmission for data block 1 is completed on the first periodic resource a after an interval of 5 ms. In case the first retransmission of data block 1 has not yet been successful, the second retransmission of data block 1 continues on the first periodic resource b 5ms later.

And a third scenario that the first periodic resource and the second periodic resource satisfy a one-to-many correspondence relationship.

In this scenario, the multiple second periodic resources correspond to a first periodic resource, and the first periodic resource is a common retransmission resource of data initially transmitted by the multiple second periodic resources.

In this scenario, since the multiple second periodic resources correspond to one first periodic resource, a new manner needs to be designed so that the receiving terminal can identify the initial transmission corresponding to the first transmission.

In one implementation, the transmitting terminal may carry the HARQ Process ID in each data block of the transmission, and the same data block carries the same HARQ Process ID.

In another implementation, special time domain relationships may be specified to identify the initial transmission to which the first transmission corresponds. For example:

on retransmission resources, only data blocks which are initially transmitted in an already passed initial transmission resource period can be transmitted;

generally, because NACK is sent from the receiving terminal to the sending terminal, if only one initially transmitted data block is erroneous in a specified initially transmitted resource period, the initially transmitted data block is retransmitted;

if there is more than one data block with errors in a specified initial transmission resource period, the sending terminal and the receiving terminal may default to some retransmission rules, for example, the first erroneous initial transmission in the initial transmission resource period is retransmitted, or the data block with the shorter initial transmission resource period is retransmitted (generally, it is considered that the data block with the shorter period may have a higher QoS requirement);

the RRC signaling shows rules for configuring retransmission, for example, when retransmission resources are sufficient, sequentially retransmitting error data blocks, and if the retransmission resources conflict, selecting and fixing data on one initial transmission resource for retransmission.

In another implementation manner, the displayed HARQ Process ID may be carried at each data transmission, for example, the transport block of the first initial transmission resource carries all Process IDs =1, the transport block of the second initial transmission resource carries all Process IDs =2, and the retransmitted data block also sets the same Process ID according to the initial transmission data, so that the receiving end can know which data is retransmitted at any time, and can perform retransmission and combining without error.

For ease of understanding, examples are illustrated below:

it is assumed that the network side device is configured with two initial transmission resources, which are a second periodic resource a and a second periodic resource b, respectively, and the periods and offsets, resource locations, and even transmission parameter configurations of the second periodic resource a and the second periodic resource b may be completely independent, and are configured according to the service requirements. In order to cooperate with the two second period resources for retransmission, a common retransmission resource, a first period resource, a period of the retransmission resource and an offset need to consider the requirements of the prior initial transmission resource period and the service QoS, if the block error rate required by the service is higher and the time delay is smaller, the retransmission resource with a shorter period can be configured to meet the requirement of retransmission as soon as possible, and if the block error rate required by the service and the time delay requirement are not high, the retransmission resource with a larger period can be configured in view of saving resources. The retransmission resource can be independent parameter configuration, but the resource size should not be smaller than the size of any initial transmission resource, so as to avoid the problem that the retransmission cannot be performed when the resource is too small. After configuration, the two initial transmission resources respectively transmit the service according to the arrival of the service, and when transmission errors occur, retransmission is performed on the nearby retransmission resources under the condition that no conflict occurs.

As shown in fig. 3d, it is assumed that the second periodic resource a is used for the initial transmission of the data block 11 and the data block 12, and the second periodic resource b is used for the initial transmission of the data block 21 and the data block 22, wherein the data block 11 and the data block 22 have retransmission requirements, and therefore, the retransmission of the data block 11 and the data block 22 can be performed on the first periodic resource.

Since the first periodic resource is a common retransmission resource of data initially transmitted by the plurality of second periodic resources, there is a high possibility that the first transmission requirement conflicts. Optionally, the performing, under the condition that there is the first requirement, the first transmission of the first data by using the first periodic resource includes:

under the condition that a first transmission demand exists and a demand conflict exists, performing first transmission of the first data by using the first periodic resource according to a first sequence;

wherein the first order comprises at least one of:

the first data has a time sequence of first transmission requirements;

the first data is subjected to a priority order of first transmissions.

In specific implementation, when there is a first transmission requirement and there is a requirement conflict, the first transmission of the first data may be performed by using the first periodic resource according to the time sequence of the first data having the first transmission requirement. For example, if there is a first transmission requirement for data block 1 and data block 2, and there is a requirement conflict, and the sending terminal receives NACK corresponding to data block 1 first and then receives NACK corresponding to data block 2, the sending terminal may first perform the first transmission for data block 1 and then perform the first transmission for data block 2.

When there is a first transmission demand and there is a demand conflict, the first transmission of the first data may be performed by using the first periodic resource according to an order from high to low of priorities of first transmissions performed on data blocks in the first data. For example, if there is a first transmission requirement for data block 1 and data block 2, and there is a conflict between the requirements, and in addition, the priority of the first transmission for data block 2 is higher than that of the first transmission for data block 1, the sending terminal may perform the first transmission for data block 2 first, and then perform the first transmission for data block 1.

Further, in practical applications, optionally, the method further includes:

under the condition that a third data block in the first data is to be transmitted, selecting a third resource in the second periodic resources to perform initial transmission of the third data block, wherein the third resource is a resource which meets the transmission condition of the third data block on a first time domain in the current remaining available resources;

and under the condition that the third data block has a first transmission requirement, selecting a fourth resource in the first periodic resource to perform first transmission of the third data block, wherein the fourth resource is a resource which meets the transmission condition of the third data block in a first time domain in the current remaining available resources.

It should be understood that the third data block may be any data block in the first data.

In practical application, after receiving the first periodic resource and the second periodic resource, the terminal can know the resource which can be freely used by itself, so that when the UE has a data block to transmit, the closest resource meeting the transmission condition of the data block in the time domain can be selected for transmission.

When the data to be transmitted needs to be transmitted, the sending terminal can select the nearest resource suitable for transmission in the time domain to perform initial transmission, and if ACK feedback of the opposite terminal is received, one-time successful transmission is completed. If NACK feedback of the opposite end is received, retransmission is carried out on the latest retransmission-suitable resource bound with the initial transmission position, feedback is waited for again, if NACK is carried out again, retransmission resource retransmission is selected again until success is achieved, and if no retransmission-suitable resource exists, the retransmission is abandoned.

It should be noted that the correspondence between the first periodic resource (i.e., retransmission resource) and the second periodic resource (i.e., initial transmission resource) is only an example. In practical application, the number of the initial transmission resources and the number of the retransmission resources are configurable, various combinations can be supported, reasonable configuration is carried out according to needs, and reasonable compromise is carried out between meeting business requirements and resource efficiency. The retransmission times may also be multiple times, that is, under the condition that retransmission still fails for one data block, retransmission may also be performed again to meet a certain block error rate requirement, and the data block retransmitted again may still complete dynamic identification with the initially transmitted data in an explicit Process ID manner or a predetermined/configured manner.

In addition, in the above description and examples, a set of corresponding periodic resources is configured as an example, if necessary, the network side may completely configure multiple sets of such resources for the UE, and the number of retransmission resources carried by each set of resources is configurable and may not be equal, depending on service requirements.

Compared with the first embodiment, the first transmission and the retransmission adopt different periodic resources for transmission, so that a simpler and faster retransmission combining effect can be obtained.

However, since the probability of retransmission is relatively low, for example, approximately 10% -0.1%, most of the retransmission resources are not used, and therefore, compared with the first embodiment, the resource utilization rate is relatively low.

In order to improve the resource utilization rate, optionally, under the condition that the sending terminal has no first transmission requirement, the sending terminal is fed back to the network side device without using the first periodic resource.

Therefore, the network side can use the unused retransmission resources for other scheduling, and further can improve the resource utilization rate.

In a specific implementation, optionally, the feeding back, to the network side device, that the sending terminal does not need to use the first periodic resource includes:

in a first mode, first indication information is sent to the network side device, where the first indication information is used to indicate that the sending terminal does not need to use the first periodic resource; or the like, or, alternatively,

and stopping sending second indication information to the network side equipment, wherein the second indication information is used for indicating that the sending terminal needs to use the first periodic resource.

In a specific implementation, the first indication information and the second indication information may be Resource Skip (Resource Skip) signaling, and the Resource Skip signaling may be specifically represented as L1 signaling or Medium Access Control (MAC) signaling.

If the L1 signaling is used, the resource location and configuration of the L1 signaling may also be allocated together when allocating the initial transmission and retransmission resources, because its location is also related to the initial transmission, the transmitting terminal can transmit after receiving feedback, before retransmitting the resources next time.

If the MAC signaling is used, the MAC signaling may correspond to a periodic resource on the Uu interface, where the periodic location is located between the initial transmission and the retransmission, and is used to indicate that the subsequent retransmission is not used.

In the first mode, when the sending terminal receives the ACK feedback from the receiving terminal and determines that the retransmission resource is not used, the uplink display signaling informs the network side device that all the retransmission resources bound with the initial transmission are not used next.

In the second mode, the sending terminal may implicitly notify the network side device that all retransmission resources bound with the initial transmission need not be used next when receiving the ACK feedback of the receiving terminal and determining that the retransmission resources are not used.

In the second mode, the second indication information is sent when the retransmission resource needs to be used, and if the second indication information is not sent, the retransmission resource is not used. Therefore, the probability of retransmission is low, and the sending probability of the second indication information is less than that of the first indication information, so that the uplink signaling overhead can be saved in the second mode compared with the first mode.

In this embodiment of the present invention, further, the first configuration information may be further configured to configure at least one of transmission parameter information and usage restriction information of the first periodic resource.

Wherein the transmission parameter information of the first periodic resource may include at least one of:

an antenna parameter;

a reference signal parameter;

power control parameters;

coding and transmission parameters such as Modulation and Coding Scheme (MCS) and Transport Block Set (TBS);

HARQ process parameters;

control information and feedback parameters, etc.

The usage restriction information of the first periodic resource may be used to restrict at least one of:

logical channel information transmitted by the first periodic resource;

a transmission priority parameter of data transmitted by the first periodic resource.

The logical channel information may include information such as a service data type. For example, the network side device may limit transmission of data of a specific service only on the first periodic resource.

In this embodiment of the present invention, optionally, the first periodic resource is used for first transmission of first data of a sidelink. Of course, in other embodiments, the first periodic resource may also be used for the first transmission of the first data of other links, such as the Uu link.

In a scenario where the first periodic resource is used for a first transmission of first data of a sidelink, further, after the receiving first configuration information, the method further comprises:

and sending the first configuration information to a receiving terminal through a secondary link.

Similarly, after receiving the second configuration information, the sending terminal may also send the second configuration information to the receiving terminal through the secondary link.

Therefore, the receiving terminal can obtain the resource positions of initial transmission and retransmission, and can more conveniently obtain the relationship between initial transmission and retransmission, thereby facilitating retransmission combination. In specific implementation, the receiving terminal may retransmit and combine in the physical layer, and certainly, the receiving terminal may also abandon the retransmission and combination in the physical layer, and may perform self-decoding no matter the retransmission and the initial transmission, and deliver the decoded data to the higher layer for repeat detection after the decoding is correct.

Of course, in some embodiments, the receiving terminal may not acquire the first periodic resource and the second periodic resource, and in this embodiment, the receiving terminal may attempt to decode its data in a resource pool of a larger range, where the resource pool is greater than or equal to all the periodic resources allocated to the transmitting terminal, and the receiving terminal may receive its data (determined according to the Destination ID) and process it, and may perform retransmission and combining if the HARQ process ID and the initial retransmission identifier can be acquired.

Therefore, in practical application, a receiving terminal can receive own data in a large receiving range according to Destination ID, decode the data correctly and deliver the decoded data to a high layer, and the high layer detects repeated data; or, multiple sets of configuration and repeat transmission information are configured to the receiving terminal/the sending terminal by the network side, the multiple sets of configuration and repeat transmission information are transmitted to the receiving terminal through the Sidelink interface message, the receiving terminal knows that the resource positions send repeated data in the same period, certain merging decoding can be carried out, and then correct decoding data is sent to a high layer.

It should be noted that, in the embodiment of the present invention, retransmission and repeated transmission are different in that: the requirements for retransmission are: receiving NACK fed back by a receiving terminal; however, the repeated transmission does not pay attention to the feedback result of the receiving terminal, and even if the receiving terminal feeds back ACK, the transmitting terminal may perform the repeated transmission of data, and therefore, the repeated transmission may also be referred to as active retransmission or duplicate transmission.

The repeated transmission can meet the requirements of time delay and block error rate of the service, and simultaneously reduces the waste of resources. For example, after receiving N resource configurations, for a transmitting terminal, according to a situation that a service arrives, for example, a piece of data arrives, the same repeated data is transmitted at all the N resource locations.

The method improves the block error rate requirement and reduces the retransmission time delay by active retransmission, is suitable for services with higher requirements on time delay and block error rate, and can be configured based on the type of the service. This approach can also be multiplexed with other embodiments, such as where one service configures a repeat mode and the remaining services can use a retransmission mode. For the use of the initial transmission period resource and the retransmission period resource, the RRC may explicitly configure its rules, such as which services are allowed to be used, which services are restricted to be used, when a collision occurs, what the priority is, and so on.

It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.

The embodiment of the invention can configure and control the periodic resources through RRC, wherein the periodic resources and the use rules are configured for retransmission by RRC signaling, and the use of the resources by initial transmission and retransmission mainly comprises the following modes and combinations:

RRC signaling allocates one or more periodic resources, and each periodic resource can be used for initial transmission and retransmission at the same time;

RRC signaling allocates independent resource allocation for initial transmission and retransmission;

RRC signaling allocates one or more sets of periodic resources, each set of resources comprises a primary transmission resource and N corresponding retransmission resources;

RRC signaling simultaneously allocates two or more than two periodic resources for initial transmission and active retransmission/duplicate transmission;

RRC signaling configures the use rule of the initial transmission resource;

RRC signaling configures a usage rule of retransmission resources, and optionally may include a priority order when there is a collision;

RRC signaling configures feedback information of a Uu interface for sending UE, and the UE can timely feed back information whether periodic resources are used;

the configured network side sends the configuration information to the sending end UE;

for the receiving end UE, the configuration may also be obtained from the network side, or obtained from the sending end UE.

The embodiment of the invention supports the configuration of retransmission resources through RRC signaling, avoids the dynamic retransmission resource scheduling across RATs, ensures the effect of Sidelink data transmission, and improves the resource utilization rate and the system efficiency.

In the resource allocation method of this embodiment, the resource used for retransmission or repeated transmission of the data may be a periodic resource, so that even in a scenario that dynamic scheduling of retransmission resources is not supported, the resource allocation for retransmission or repeated transmission may be implemented, so that under the condition that there is a retransmission or repeated transmission demand, the data may be successfully retransmitted or repeatedly transmitted, and further, the reliability of data transmission may be improved.
