Description

Method, network equipment and terminal equipment for transmitting uplink information without authorization

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a network device, and a terminal device for transmitting uplink information without authorization.

Background

In a wireless cellular network, for example, in a Long Term Evolution (LTE) system, before sending uplink data, a terminal device first needs to establish a radio resource control connection with a base station, enter a radio resource control connection state, and after obtaining an authorization instruction of the base station, can send the uplink data according to an instruction requirement of the base station. This method of sending data upstream is called grant transmission. Since the terminal device needs a large amount of signaling interaction from the time when it is determined that there is uplink data to be sent to the time when the uplink data is sent out from the air interface, the time delay of the authorized transmission is large.

Large-scale machine communication is an important application scenario in the fifth generation communication technology in the future. In an MTC communication scenario, the number of terminal devices is huge, the service type is mainly a small data packet service, and there is a certain requirement for low latency. In this scenario, the unlicensed transmission is considered to be an uplink data transmission method better than the licensed transmission. The basic idea of the authorization-free transmission is that data is transmitted from the beginning to the end, that is, when the terminal determines that there is uplink data to be transmitted, the terminal does not need to perform the interaction process of transmitting an uplink scheduling request and waiting for receiving an authorization instruction of the base station, but directly transmits the data to the base station after certain processing.

Low-Latency high-reliability Communication (URLLC) is also an important scenario in 5G. For some services such as car networking, unmanned driving, industrial control, etc., system capacity is not a major issue, but there are high requirements for delay and reliability. Therefore, the unlicensed transmission is considered to be more suitable for a low-latency high-reliability scenario.

In the method for transmitting uplink information without grant provided in the prior art, the same transport block TB is transmitted multiple times on consecutive uplink subframes without waiting for Acknowledgement (ACK) or Negative Acknowledgement (NACK). This technique is called subframe Bundling (TTI Bundling). However, the subframe bundling technique only utilizes time diversity to shorten the delay, and the flexibility is low.

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, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

The technical scheme provided by the embodiment of the invention can be applied to various communication systems of a wireless cellular network, such as: global System for Mobile communications (GSM) System, Code Division Multiple Access (CDMA) System, Wideband Code Division Multiple Access (WCDMA) System, General Packet Radio Service (GPRS) System, Long Term Evolution (LTE) System, Universal Mobile Telecommunications System (UMTS), next generation Mobile communications System (e.g., 5G), and Machine to Machine (M2M) communication System, etc.

First, a brief description will be given of related concepts related to the embodiments of the present invention.

It should be appreciated that conventional licensed spectrum resources generally require a national or local wireless committee approval for the spectrum resources that may be used. Different systems (e.g., LTE systems, WiFi systems) or systems of different operators may not share the usage of the licensed spectrum resources.

Conventional unlicensed spectrum resource transmission refers to that, without system allocation, each communication device can share and use resources included in an unlicensed spectrum. Resource sharing on the unlicensed frequency band means that only the limit on indexes such as transmission power, out-of-band leakage and the like is specified for the use of a specific frequency spectrum, so as to ensure that a plurality of devices commonly using the frequency band meet basic coexistence requirements.

It should be noted that, the unlicensed transmission according to the embodiment of the present invention is different from the unlicensed spectrum resource transmission described above, and a process of allocating unlicensed transmission resources to a user through a user access network and a base station is required. When the user has data to send, it sends directly on the resource without authorization allocated by the base station. Therefore, the unlicensed spectrum resource transmission described in the embodiment of the present invention is different from the conventional unlicensed spectrum resource transmission in that resources for unlicensed transmission in the embodiment of the present invention need to be allocated in advance by a system.

In the embodiment of the present invention, the network device can perform wireless communication through the above-mentioned unlicensed transmission. In addition, the network device may also communicate wirelessly through the licensed spectrum resource transmission.

Various embodiments are described herein in connection with a terminal device. A terminal device may also be referred to as a User Equipment (UE), a mobile station, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment, etc. The terminal device may be a station (station, ST) in a Wireless Local Area Network (WLAN), and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, and a mobile station in a future communication network (e.g., 5G) or a terminal device in a future evolved PLMN network, and so on.

In the embodiment of the invention, the terminal equipment can carry out wireless communication through the authorization-free transmission. In addition, the terminal device may also perform wireless communication through authorized spectrum resource transmission.

The network device and the terminal device described in the embodiments of the present invention may be implemented by way of a computer device (or system) 100 as shown in fig. 1.

Alternatively, it may be possible to perform more operations or steps than those shown in the embodiments of the present invention.

For convenience of understanding and explanation, the following describes a method for transmitting uplink information without grant according to an embodiment of the present invention, with only a UE and a base station as examples of a terminal device and a network device, respectively.

Fig. 2 shows a schematic interaction diagram of a method for unlicensed uplink information transmission according to an embodiment of the present invention. As shown in fig. 2, the method mainly includes steps 210 to 230.

210. The UE determines a plurality of target multi-access resources MARs carrying at least one redundancy version, each redundancy version at least comprises uplink information which needs to be sent to a base station by the terminal equipment, and the plurality of target MARs can be distinguished through frequency diversity or signature diversity.

It should be understood that a Multiple Access Resource (MAR) is composed of a Multiple Access Physical Resource (MAPR) and a Multiple Access Signature (MA Signature, MAs). Wherein MAPR refers to Time Frequency Resource (Time Frequency Resource) exclusively. And the MAS includes at least one of, but not limited to: a Codebook (Codebook), a Codeword (Codeword), a Sequence (Sequence), an interleaving pattern (Interleaver pattern), a mapping pattern (mapping pattern), a Demodulation reference signal (Demodulation reference signal), a Preamble (Preamble), a Spatial-dimension (Spatial-dimension), and a Power dimension (Power dimension).

Alternatively, as one embodiment, the multiple target MARs can be distinguished by any combination of frequency diversity, signature diversity, and time diversity.

It should be noted that, when the UE sends the uplink information, one redundancy version or multiple redundancy versions may be sent, which is not limited in this embodiment of the present invention.

A redundancy version as referred to herein means that there is only one version number. Multiple redundancy versions refer to multiple version numbers. It should be understood that the Redundancy Version (RV) described in the embodiment of the present invention is used to implement a Hybrid Automatic Repeat Request (HARQ) of an Incremental Redundancy (IR), that is, Redundancy bits (Redundancy Bit) generated for Transport Blocks (TBs) are divided into a plurality of groups, each RV defines a transmission starting point, and different RVs are used for the first transmission and each retransmission, so as to implement gradual accumulation of the Redundancy bits and complete the Incremental Redundancy HARQ. More specifically, the detailed description of the redundancy version may refer to the definitions in the prior art, which are not described in detail herein. In particular, when the redundancy versions sent on the various MARs are identical, this method of incremental redundancy becomes the Chase Combining (Chase Combining, abbreviated CC) method.

Specifically, in the embodiment of the present invention, the UE determines multiple target MARs carrying at least one redundancy version, which includes multiple ways.

Mode 1

The UE determines a target MAR according to binding information, wherein the binding information is predetermined by the terminal equipment and the network equipment.

The binding information may be related to the following factors:

whether to retransmit: the UE may use the same bundling information as the initial transmission or may use different bundling information for the initial transmission during the retransmission. For example, the UE may increase the number of RVs, increase the number of MARs, or place RVs in more diverse MARs upon retransmission, etc.

Quality of Service (QoS) of UE: the UE uses different bundling information for packets with different QoS requirements. For example, for data packets with high delay requirements, frequency diversity or signature diversity is selected rather than time diversity. Alternatively, the base station may attempt decoding in a shorter time by a preset rule of the system. For another example, for a packet with a higher reliability requirement, more RVs may be transmitted, the number of MARs occupied by the RVs may be increased, the RVs may be placed in MARs with higher diversity, and so on.

Specifically, the Bundling information in the embodiment of the present invention may include at least one of the following information: the number of redundancy versions used when sending the uplink information, the number and size of the MAR occupied by the redundancy versions used when sending the uplink information, the location of the MAR, the mapping relationship between the redundancy versions used when sending the uplink information and the MAR, the number of the load-bearing redundancy versions on each MAR, and the Modulation and Coding Scheme (MCS) that each MAR can use.

Optionally, as an embodiment, each target MAR in the multiple target MARs carries identification information of the UE and a version number of the carried redundancy version, each target MAR carries a second control channel, the second control channel carries second indication information, and the second indication information is used to indicate the identification information and the version number, so that the base station combines the at least one redundancy version to obtain the uplink information.

When a MAR carrying a redundancy version (i.e., a target MAR) carries identification information of a UE and a version number of an RV, each target MAR may carry a control channel (i.e., a second control channel) separately, and the control channel carries indication information (i.e., second indication information) of the UE identification information and the RV version number. Thus, when receiving the RV, the base station receives the UE identity information and the version number of the RV, which are carried on the MAR at the same time. The base station can acquire the version number of each RV and the UE to which the RV belongs based on the identification information and the version number of the UE, so that the RV of each UE can be merged and decoded.

That is, in the mode 1, which MARs are used when the UE transmits the redundancy version is determined entirely by the system definition. Here, the system definition may mean that it is pre-agreed by the base station and the UE. Alternatively, system definition may also refer to specification by a standard.

Mode 2

The UE refers to the bundling information determination.

Optionally, as an embodiment, the determining, by the UE, a plurality of target MARs carrying at least one redundancy version includes:

the UE determines a plurality of first MARs corresponding to at least one redundancy version according to binding information, wherein the binding information is predetermined by the UE and network equipment, and the binding information comprises at least one of the following information: the number of redundancy versions used when sending the uplink information, the number and size of MARs occupied by the redundancy versions used when sending the uplink information, the positions of the first MARs, the mapping relation between the redundancy versions used when sending the uplink information and the first MARs, the number of the redundancy versions borne on each first MAR and the modulation and coding strategy MCS which can be used by each first MAR;

the UE determines the plurality of target MARs from the plurality of first MARs.

It should be understood that the first MAR herein refers to a system defined MAR carrying an RV. The target MAR is the MAR that the UE determines from the plurality of first MARs to use when actually transmitting the RV.

It can be understood that, in the mode 2, the network side can only know the MAR predefined by the system (i.e., the network side only knows the first MAR), and does not know the MAR used when the UE actually sends the RV. Therefore, the UE needs to inform the network device of the MAR used when the RV is actually transmitted (i.e., the target MAR).

Optionally, as an embodiment, the method further includes:

and the UE sends a third control channel to the network equipment, wherein the third control channel carries third indication information, and the third indication information is used for indicating the plurality of target MARs determined by the UE based on the binding information, so that the network equipment can receive the at least one redundancy version on the target MARs in the plurality of first MARs according to the binding information and the third indication information.

As can be seen, in mode 2, the UE determines the target MAR based on the bundling information. Unlike equation 1 above, in this approach, the UE simply defines the system as a reference when transmitting the RV. Therefore, the MAR carrying the RV (i.e., the target MAR) transmitted by the UE may not be completely system defined. In this way, the UE needs to inform the base station of the MAR that has been selected by itself to transmit the RV.

Mode 3

The UE determines autonomously.

Optionally, as an embodiment, the method further includes:

the UE sends a first control channel to the network equipment, wherein the first control channel carries first indication information, and the first indication information is used for indicating the target MARs, so that the network equipment can receive the at least one redundancy version on the target MARs according to the first indication information.

It can be understood that since in mode 3, the MAR used by the UE when transmitting the RV (i.e., the target MAR) can be completely determined by the UE itself. Therefore, in this way, the UE also needs to inform the network side of the MAR of the bearer RV selected by the UE.

After determining the target MAR based on the above manners, the UE may send one or more redundancy versions to the base station on the target MAR. Each redundancy version at least comprises uplink information which needs to be sent to the base station by the UE.

The target MAR (i.e., the MAR for carrying the redundancy version RV) according to the embodiment of the present invention is described in detail below with reference to several embodiments.

Fig. 3 shows one way for the UE to send one redundancy version. As shown in fig. 3, the UE sends one Transport Block (TB) at a time, and the TB has only one redundancy version.

It should be understood that, in the embodiments of the present invention, a redundancy version refers to the same version number of the redundancy version sent by the UE to the network side, i.e. there is only one version number. Similarly, the multiple redundancy versions mean that the redundancy version sent by the UE to the network side has multiple version numbers.

In the following, a case where only one redundancy version is carried on the target MAR will be described.

FIG. 4 shows a schematic diagram of a MAR in accordance with an embodiment of the present invention. In this embodiment, time-frequency resource blocks with continuous time and fixed length are defined as a resource group by using the same Multiple Access Signature (MAS). The multiple MARs included in each resource group may employ different Modulation and Coding Schemes (MCS). Wherein the partitioning of each resource group is known by the UE and the base station prior to transmission of the uplink information.

The resource group described in the embodiments of the present invention may be selected by the UE itself, or may also adopt a semi-static configuration mode.

It should be understood that the semi-static configuration described herein refers to a pre-configuration based on the network side when the UE initially transmits the RV, and stores the configuration information of the network side. At regular intervals, the UE transmits the RV using the same MAR resource as when the RV was transmitted for the first time.

As shown in fig. 4, UE #1 selects resource group #1, UE #2 selects resource group #3, and UE #3 selects resource group 4. For each UE, a redundancy version including uplink information is placed on all MARs in the selected resource group.

Correspondingly, on the network side, the base station performs merging decoding on the redundancy versions on all the MARs on each resource group. And under the condition of correct decoding, the base station can obtain the uplink information sent by the UE.

FIG. 5 shows a schematic of a MAR according to another embodiment of the present invention. As shown in fig. 5, in this embodiment, time-frequency resource blocks with continuous time, the same multiple access signature and unfixed length are defined as a resource group.

As shown in fig. 5, resource group #1 and resource group #2 have different lengths from resource group #3 and resource group # 4. UE #1 selects resource group #1, and UE #2 selects resource group # 3. UE #3 selects resource group # 4. The UE places the RV for the respective TB on each MAR in the selected resource group.

Correspondingly, on the network side, the base station combines and decodes the redundancy versions on all the MARs included in each resource group to obtain the uplink information sent by the UE.

FIG. 6 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, a time-frequency resource block with discontinuous time, the same multiple access signature and a non-fixed length is defined as a resource group. In each resource, placing (or carrying) redundancy versions multiple MARs may be contiguous or may not be contiguous in the time domain.

As shown in fig. 6, resource group #1 is not contiguous in the time domain. Resource group #3 and resource group #4 are contiguous in the time domain. Among them, UE #1 selects resource group #1, UE #2 selects resource group 3, and UE #3 selects resource group 4. Each UE places a respective TB-generated RV on each MAR in a selected resource group.

Correspondingly, the base station performs merging decoding on the redundancy versions on all MARs on each resource group to obtain the uplink information sent by the UE.

FIG. 7 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, a time-frequency resource block, which is discontinuous in time, adopts the same multi-access signature, is not fixed in length, and is located in different frequency domains, is defined as a resource group.

As shown in fig. 7, resource group #1 selects discontinuous resources in the time domain and is distributed in different frequency domains. UE #1 selects resource group #1, and UE #2 selects resource group # 2. UE #3 selects resource group # 3. The UE places the RV generated by the respective TB on each MAR in the selected resource group.

Correspondingly, the base station combines and decodes the redundancy versions on all MARs of each resource group, thereby acquiring the uplink information sent to the base station by the UE.

FIG. 8 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, a time-frequency resource block, which is discontinuous in time, adopts different multiple access signatures, is not fixed in length, and is located in different frequency domains, is defined as a resource group.

As shown in fig. 8, resource group #1 selects discontinuous resources in the time domain and is distributed in different frequency domains. UE #1 selects resource group # 1. UE #2 selects resource group # 2. UE #3 selects resource group # 3. The UE places the respective TB-generated RVs on each MAR in the selected resource group.

Correspondingly, on the network side, the base station combines and decodes the redundancy versions of all MARs on each resource group to obtain the uplink information sent to the base station by the UE.

Fig. 9 shows another way for the UE to send one redundancy version. In this embodiment, the UE sends one Transport Block (TB) at a time, and one TB has only one redundancy version. Control words are transmitted on each MAR.

FIG. 10 shows a schematic of a MAR according to yet another embodiment of the present invention. As shown in fig. 10, the UE selects a different number of MARs in different locations to send redundancy versions, while transmitting a control word on each MAR.

Optionally, as an embodiment, the control word carries the UE ID and End (End) position indication information.

Correspondingly, the base station demodulates the control words from each MAR. When detecting that the End position indication (End) of the control word is 1, merging and decoding all previously received RVs carried on the MAR and having the same UE ID carried in the control word, and acquiring uplink information sent by the UE.

It should be understood that, in the embodiment of the present invention, it is only exemplified that the End of the sequential uplink transmission is indicated when the End position indication (End) is "1". Obviously, the End position indication (End) information may be set in various forms, for example, the End position indication (End) may also be set to "0". The embodiment of the present invention is not limited thereto.

Optionally, as an embodiment, the control word carries the UE ID and a maximum transmission time indication (Bundling Size).

Correspondingly, when the base station detects that the number of MARs from the same UE ID is equal to the maximum transmission times, the uplink transmission of the UE identified by the UE ID is finished.

Correspondingly, the base station combines and decodes a plurality of redundancy versions of the same UE ID to obtain the uplink information sent by the UE.

Optionally, as an embodiment, the control word carries a UE ID, a maximum transmission number indication (Bundling Size), and an End position indication (End).

Correspondingly, when the base station detects that the number of MARs from the same UE ID is equal to the maximum transmission times or the ending position indication (End) of the control word is '1', the uplink transmission of the UE identified by the UE ID is ended. And the base station combines and decodes all received RVs loaded on the MAR and having the same ID with the UE carried in the control word to obtain the uplink information sent by the UE.

It should be noted that the resource group described in the above embodiments may be selected by the UE itself. Or may be specified by a standard or pre-agreed by the UE and the base station. The UE places one or more RVs needing to be transmitted on each MAR in the resources and sends the MARs to the network side.

Optionally, as an embodiment, when the version number of the at least one redundancy version sent by the UE to the network side is the same, the uplink data transmitted to the network side on each target MAR is the same.

The following describes a case where there are a plurality of redundancy versions.

Fig. 11 shows a manner in which a UE transmits multiple redundancy versions according to an embodiment of the present invention. In this embodiment, the UE transmits one TB at a time, which includes a plurality of redundancy versions. As shown in fig. 11, the TB of UE #1 includes 4 redundancy versions, RV0, RV1, RV2, and RV3, respectively. The TBs of UE #2 and UE #3 each include 2 redundancy versions, both RV0 and RV 1.

FIG. 12 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, a time-frequency resource block with discontinuous time, different multiple access signatures, and unfixed length and on different frequency domains is defined as a resource group.

As shown in fig. 12, resource group #1 may transmit 4 different versions of RVs, RV0, RV1, RV2, and RV3, respectively, and be distributed over different time and frequency domains. Resource group #2 may transmit 2 versions of RV, RV0 and RV 1. Resource group #3 transmits only one redundancy version RV 0. UE #1 selects resource group #1, UE #2 selects resource group #2, and UE #3 selects resource group # 3. Each UE places the RV generated by a respective TB on each MAR in a selected resource group.

Correspondingly, at the network side, the eNB combines the redundancy versions on all the MARs of each resource group and then decodes the combination to obtain the uplink information sent to the eNB by the UE.

Fig. 13 shows another way for the UE to transmit multiple redundancy versions according to an embodiment of the present invention. In this embodiment, the UE transmits one TB at a time and has multiple RVs. The UE selects MARs with different numbers and different positions for transmission. The RV version carried on each MAR is fixed. Control words are transmitted on each MAR. The control word carries a UE ID, a maximum transmission time indication (Bundling Size), and an End position indication (End).

Correspondingly, when the base station detects that the number of MARs from the same UE ID is equal to the maximum transmission times or the ending position indication (End) of the control word is '1', the uplink transmission of the UE is ended.

FIG. 14 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, the UE transmits one TB at a time and has multiple RVs. The UE selects MARs with different numbers and different positions for transmission. The UE places the RV of the MAR specified version number on a different MAR and places a control word on all MARs.

Optionally, as an embodiment, the control word carries an RV ID to indicate a version number of an RV carried on the MAR.

Correspondingly, on the network side, the base station obtains the version number of the RV according to the pre-correspondence rule of MAR and RV, and combines the version number, specifically, for the RV with the same version number, a Chase Combining (CC) method is used. For RVs with different version numbers, an Incremental Redundancy (IR) merging method is adopted.

FIG. 15 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, after demodulating the control word of each MAR, the eNB counts the MARs from each UE, and when the count exceeds a threshold, performs merging decoding on all received RVs from each UE respectively.

As shown in fig. 15, assume that the eNB starts the merging decoding after receiving 2 MARs from the same UE. In slot #2, the MAR resource selected by UE #1 collides with the MAR resource selected by UE # 2. In slot #3, the eNB receives the number of MARs from UE #1 reaching the threshold. The eNB combines RV0 and RV2 for decoding. And if the decoding is successful, the eNB feeds back ACK to the UE. If the decoding fails, the eNB performs second merging decoding when receiving the RV 3. The embodiment may enable the eNB to start the merging decoding mechanism when the partial control word is collided.

FIG. 16 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, the eNB performs the merging decoding on the redundancy versions of all UEs at regular time intervals (or time intervals). As shown in fig. 16, it is assumed that the eNB performs the combining decoding every two slots. In slot 2, the eNB decodes the RV0 received from UE #1, decodes the RV0 from UE #2, and combines and decodes the 2 RVs 0 from UE # 3. And if the decoding is successful, the eNB feeds back ACK to the UE. If the decoding fails, the eNB performs second merging decoding in the time slot # 4. The embodiment may enable the eNB to start the merging decoding mechanism when the partial control word is collided.

Fig. 17 shows another way for the UE to send multiple redundancy versions according to an embodiment of the present invention. In this embodiment, the UE transmits multiple TBs at a time and has multiple RVs. The UE selects MARs with different numbers and different positions for transmission. While control words are transmitted on each MAR. Unlike the previous embodiment, the control word carries the TB ID in addition to the UE ID, the maximum transmission Size (Bundling Size), and the End position indication (End). The TB ID is used to distinguish to which TB the RV belongs.

FIG. 18 shows a schematic of a MAR according to yet another embodiment of the present invention. In this embodiment, correspondingly, when performing combining and decoding, the base station needs to combine and decode redundancy versions with the same UE ID and the same TB ID, so as to obtain uplink information sent by the UE.

In the above embodiments, the eNB feeds back an ACK to the UE after successful decoding. And the UE starts to send the uplink information of the next TB after receiving the ACK. If the transmission of the uplink information fails, the uplink information with transmission failure can be retransmitted in the following two ways.

(1) And the eNB feeds back NACK information to the UE.

Correspondingly, the UE retransmits the NACK message after receiving the NACK message.

(2) The eNB does not feed NACK information back to the UE.

Correspondingly, if the UE does not receive the ACK information fed back by the eNB in the preset time period, it determines that the transmission fails, and performs retransmission. The same resource group or MAR as before may be selected for retransmission. Different resource groups or MARs may also be reselected. For example, a higher number of MARs with higher diversity are used in retransmissions to improve the reliability of the transmission.

It can be seen that, in the method for transmitting uplink information without authorization according to the embodiment of the present invention, the UE transmits the redundancy version carrying the uplink information through frequency diversity or signature diversity (or any combination of time diversity, frequency diversity, and signature diversity). Compared with the prior art, the flexibility of transmitting the uplink information is improved on the premise of ensuring low time delay.

220. The UE transmits the at least one redundancy version to the base station over the plurality of target MARs, and the base station receiving terminal device transmits the at least one redundancy version to the base station over the plurality of target MARs.

As described above, the UE determines the MAR used when transmitting the redundancy version (i.e., the target MAR) in different manners. Correspondingly, the base station receives the MAR used when the UE sends the redundancy version in different modes, so that the redundancy version sent by the UE is received on the target MAR.

For example, in the above manner 1, the UE selects the MAR to transmit the redundancy version according to the preset rule. Correspondingly, the base station can acquire the MAR used by the UE for sending the redundancy version according to the preset rule, so that the redundancy version is received on the corresponding MAR.

For another example, in the mode 2, the UE refers to a preset rule (i.e., preset bundling information) and informs the base station of the actually selected MAR when transmitting the redundancy version. Correspondingly, the base station can also know which MAR resources the UE has sent the redundancy version on, and receive the redundancy version.

For another example, in the method 3, the UE autonomously determines the MAR resource used when transmitting the redundancy version and informs the base station (for example, transmits the indication information) of the MAR used when transmitting the redundancy version. Correspondingly, the base station receives the redundancy version according to the indication information target MAR sent by the UE.

230. And the base station combines the at least one redundancy version to obtain the uplink information.

Specifically, the base station receives the redundancy version sent by the UE, and performs merging and decoding to obtain the uplink information sent by the UE.

Optionally, the base station may perform merging decoding on the received multiple RVs of one UE when the number of received MARs sent by the UE reaches a preset number based on a preset number of MARs. This embodiment is described with reference to fig. 15. For brevity, no further description is provided herein.

Optionally, the base station performs merging decoding on the received redundancy version sent by one UE based on a preset time period. This embodiment is described with reference to fig. 16. And will not be described in detail herein.

It should be noted that the number of MARs included in the resource group in each of the above embodiments is merely an example, and should not limit the scope of the embodiments of the present invention.
