Description

[0001] This application is a divisional application of the Chinese patent application with application number 201580069747.5, application date July 30, 2015, and invention name “A communication method and communication device”, all contents of which are incorporated into this application by reference. Technical Field

[0002] The present invention relates to the field of communication technology, and in particular to a communication method and communication equipment. Background Art

[0003] The Long Term Evolution (LTE) communication system aims to provide low-latency and high-reliability data transmission.

[0004] In current communication methods, in order to improve the reliability of data transmission between the sender and the receiver, multiple retransmissions are usually used, for example:

[0005] When the receiving end fails to decode a data packet, the receiving end will feedback a negative confirmation to the sending end; after receiving the negative confirmation feedback from the receiving end, the sending end will resend the unsuccessfully decoded data packet to the receiving end, and the above process can be performed multiple times.

[0006] However, the above-mentioned method of adopting multiple retransmissions ensures the reliability of data transmission to a certain extent, but multiple transmissions inevitably increase the data transmission delay.

[0312] In the communication method provided by an embodiment of the present invention, a communication device determines a parallel HARQ communication indication, and sends or receives data in a parallel HARQ manner according to the parallel HARQ communication indication. In an embodiment of the present invention, the parallel HARQ communication indication is used to instruct the communication device to send or receive data in a parallel HARQ manner; for example, it may be an HARQ configuration parameter for the communication device to send or receive data in a parallel HARQ manner.

[0314] The communication device in the embodiment of the present invention may be a network device or a user equipment.

[0315] The present invention will hereinafter describe in detail the communication method and communication device provided by the embodiments of the present invention in conjunction with specific embodiments.

[0316] Figure 4 FIG. 1 is a flow chart of a communication method provided by an embodiment of the present invention. Figure 4 The execution subject of the communication method shown is a user device, that is, the communication device is a user device, such as Figure 4 Shown include:

[0317] S101: The user equipment determines a parallel HARQ communication indication.

[0318] In the embodiment of the present invention, the parallel HARQ communication indication is used to instruct the user equipment to send or receive data in a parallel HARQ manner.

[0319] The user equipment sending data in parallel HARQ mode means that the user equipment sends at least one data packet with the same content in the same transmission time interval. For example, the user equipment can send at least one data packet with the same content to the base station on different physical resources in the same transmission time interval such as TTI (Transmission Time Interval).

[0320] Specifically, the so-called identical content can be understood as the identical content contained in the MAC service data units (Medium Access Control Service Data Units, MAC SDU), or the identical content contained in the Medium Access Control Protocol Data Units (Medium Access Control Packet Data Unit, MAC PDU), or the identical content of the transport blocks (Transport Block, TB).

[0321] The user equipment receiving data in a parallel HARQ manner means that the user equipment receives at least one data packet with the same content in the same transmission time interval, and combines and decodes the at least one received data packet with the same content. For example, the user equipment may receive at least one data packet with the same content sent by the base station on different physical resources in the same transmission time interval such as TTI, and combine and decode multiple data packets with the same content to further enhance the data decoding success rate.

[0322] Specifically, merged decoding may refer to the user device directly merging and decoding multiple data packets with the same content, or the user device first decodes some of the data packets. If the decoding is unsuccessful, all multiple data packets with the same content are merged and decoded. The specific decoding process is not limited by the present invention.

[0323] It should be noted that the embodiment of the present invention does not limit the specific transmission time interval within which the user equipment sends or receives the data.

[0324] It should be further explained that the parallel HARQ communication indication determined by the user equipment in the embodiment of the present invention may be sent by a network device such as an eNB, and the user equipment receives the parallel HARQ communication indication sent by the network device, which is not limited in the embodiment of the present invention.

[0325] S102: The user equipment sends or receives data in a parallel HARQ manner according to the parallel HARQ communication indication.

[0326] In the embodiment of the present invention, the user equipment sends data in a parallel HARQ manner, which may be that the user equipment sends uplink data to a network device such as an eNB.

[0327] Specifically, for a user equipment sending uplink data in a parallel HARQ manner, the user equipment simultaneously performs multiple HARQ transmissions according to commands from network equipment such as an eNB, such as uplink authorization, and the parallel HARQ communication indication, such as uplink HARQ configuration parameters, and maps the uplink data to multiple different physical resources (including at least one different domain among time, frequency domain, code domain, etc.) for parallel transmission.

[0328] In the embodiment of the present invention, the user equipment receives data in a parallel HARQ manner, which may be that the user equipment receives downlink data sent by a network device such as an eNB.

[0329] Specifically, for a user equipment receiving downlink data in a parallel HARQ manner, the user equipment may perform multiple HARQ transmissions simultaneously, such as parallel transmissions in multiple different physical resources (including time, frequency domain, code domain, etc.), according to a command of a network device such as an eNB, such as a downlink assignment (DL Assignment), and the parallel HARQ communication indication, such as a HARQ configuration parameter, such as a downlink HARQ configuration parameter. Furthermore, multiple parallel transmitted data may be combined and decoded.

[0330] Specifically, in the embodiment of the present invention, the physical resources used by the user equipment to send uplink data in a parallel HARQ manner or to receive downlink data in a parallel HARQ manner may be indicated by a command sent by the eNB. For example, the command sent by the eNB may carry all the physical resource information used by multiple parallel HARQ transmissions; or the command sent by the eNB may also carry a part of the physical resource information used by multiple parallel HARQ transmissions, and the other physical resource information is indicated by the parallel HARQ communication, such as the HARQ configuration parameter. For example, the command sent by the eNB indicates physical resource 1, and the other physical resources are indicated by the configuration parameter; or a part of the physical resources are indicated by the command sent by the eNB, and the other physical resources are indicated by the parallel HARQ communication, such as the rules in the HARQ configuration parameter and the command sent by the eNB. For example, the command sent by the eNB indicates physical resource 1, and the rule in the HARQ configuration parameter is to use the physical resource continuously, then the user equipment can determine all the physical resources used according to the command and the rule.

[0331] In the embodiment of the present invention, the user equipment sends or receives data in a parallel HARQ manner according to the parallel HARQ communication indication, sends or receives at least one data packet with the same content within the same transmission time interval, and realizes parallel sending or receiving of data packets, which can reduce the delay, and the sending or receiving of multiple data packets within the same transmission time also improves the reliability of data transmission.

[0332] Optionally, the parallel HARQ communication indication in the embodiment of the present invention may be a HARQ configuration parameter, where the HARQ configuration parameter is a configuration parameter for the user equipment to send or receive the data in a parallel HARQ manner. The specific execution process is as follows: Figure 5 As shown, including:

[0333] S201: User equipment receives HARQ configuration parameters.

[0334] Optionally, the HARQ configuration parameters in an embodiment of the present invention may include a parallel HARQ number parameter such as a user equipment sending or receiving data in a parallel HARQ manner, wherein the parallel HARQ number parameter includes the maximum number of parallel HARQs performed each time the user equipment sends or receives the data, or the specific number of parallel HARQs.

[0335] In an embodiment of the present invention, when the parallel HARQ number parameter includes the maximum number of parallel HARQs, other signaling notification methods, such as downlink control signaling notification methods, may be used to notify the specific number of parallel HARQs currently being performed for the data sending or receiving, thereby reducing the overhead of physical channel resources and allowing the user equipment to use a different number of parallel HARQs each time it sends or receives the data, so as to dynamically adapt to changes in channel conditions and ensure low latency and high reliability of data sending or receiving.

[0336] It should be noted that the HARQ configuration parameters in the embodiment of the present invention may be set to include different contents according to actual conditions. For example, parameter information such as carrier information and feedback resource information used to indicate the user equipment to send or receive data in a parallel HARQ manner may also be included, and the embodiment of the present invention does not limit this.

[0337] It should be further explained that, in the embodiment of the present invention, the HARQ configuration parameters may include uplink HARQ configuration parameters and downlink HARQ configuration parameters, and the uplink HARQ configuration parameters indicate the configuration parameters required for the user equipment to send the data in a parallel HARQ manner, and the downlink HARQ configuration parameters indicate the configuration parameters required for the user equipment to receive the data in a parallel HARQ manner. Of course, the embodiment of the present invention is not limited to the above method.

[0338] In the embodiment of the present invention, the user equipment may receive the HARQ configuration parameters through a Radio Resource Control (RRC) message, such as a system message, or a dedicated RRC message, such as an RRC connection reconfiguration message. Of course, the embodiment of the present invention does not limit the specific receiving method of the HARQ configuration parameters, for example, it may also be received through a physical layer message or a media access control (MAC) layer message.

[0339] S202: The user equipment sends or receives the data in a parallel HARQ manner according to the HARQ configuration parameters.

[0340] In the embodiment of the present invention, the user equipment sends or receives data in a parallel HARQ manner according to the received HARQ configuration parameters, and can implement the parallel HARQ manner to send or receive data with less signaling overhead, reduce delay, and improve reliability.

[0341] Optional, in Figure 4 and Figure 5 Based on the communication execution process shown in the figure, in the embodiment of the present invention, before the user equipment sends or receives the data in a parallel HARQ manner according to the parallel HARQ communication indication, it can also receive downlink control signaling, and send or receive the data in a parallel HARQ manner according to the physical resources, modulation and coding mode, and parallel HARQ number parameters used by the user equipment to send or receive the data in a parallel HARQ manner included in the downlink control signaling. Figure 5 The method shown includes the above execution method as an example for illustration. Figure 6 As shown, including:

[0342] S301: User equipment receives HARQ configuration parameters.

[0343] S302: The user equipment receives at least one downlink control signaling.

[0344] In the embodiment of the present invention, the at least one downlink control signaling includes the physical resources, modulation and coding mode, and parallel HARQ number parameters used by the user equipment to send or receive the data in parallel HARQ mode. Of course, in the embodiment of the present invention, the downlink control signaling may also include at least one of the physical resources, modulation and coding mode, and parallel HARQ number parameters used by the user equipment to send or receive the data in parallel HARQ mode. For information not included in the downlink control signaling, other methods may be used to notify the user equipment, for example, through HARQ configuration parameters.

[0345] It should be noted that the parallel HARQ number parameter included in the downlink control signaling in the embodiment of the present invention may be the maximum number of parallel HARQs executed by the user equipment each time the data is sent or received, or may be the specific number of parallel HARQs. Of course, if the HARQ configuration parameter already includes the specific number of parallel HARQs executed by the user equipment each time the data is sent or received, then the specific number of parallel HARQs does not need to be included in the downlink control signaling.

[0346] S303: The user equipment sends or receives data in a parallel HARQ manner according to the HARQ configuration parameter and the at least one downlink control signaling.

[0347] In the embodiment of the present invention, downlink control signaling is used to notify the user equipment of information such as the physical resources, modulation and coding method, and parallel HARQ number parameters used to send or receive the data in a parallel HARQ manner, so that it is not necessary to include all parameter information for executing parallel HARQ in the HARQ communication indication.

[0348] It should be noted that, in the embodiment of the present invention, the execution process of S301 and S302 is not in order, and S301 and S302 can also be executed in parallel. Figure 6 The process shown is for illustrative purposes only.

[0349] In the embodiment of the present invention, the user equipment may receive the downlink control signaling via a Radio Resource Control (RRC) message, such as a system message, or a dedicated RRC message, such as an RRC connection reconfiguration message. Of course, the embodiment of the present invention does not limit the specific receiving method of the downlink control signaling, for example, it may also be received via a physical layer message or a media access control (MAC) layer message.

[0350] In the embodiment of the present invention, the at least one downlink control signaling may be received separately through a physical layer message. Optionally, when the at least one downlink control signaling is received separately through a physical layer message, each downlink control signaling in the at least one downlink control signaling includes at least one of all physical resources used by the user equipment to send or receive the data in a parallel HARQ manner.

[0351] Specifically, all physical resources refer to a set of physical resources used by each HARQ transmission or reception when the data is sent or received in a parallel HARQ manner.

[0352] Specifically, if the downlink control signaling is one, the downlink control signaling may include all physical resources used by the user equipment, and may also include some physical resources among all physical resources used by the user equipment. In the case where the downlink control signaling includes some physical resources among all physical resources, other physical resources used by the user equipment may be obtained through the physical resources included in the downlink control signaling and a predetermined rule. For example, the downlink control signaling includes one physical resource, and the predetermined rule is that a set number of physical resources of a physical resource included in the downlink control signaling that are continuous in the frequency domain are all physical resources allocated to the user equipment for use, such as Figure 7 As shown, the physical resource included in the downlink control signaling is TB1, and the next physical resource TB2 continuous in the frequency domain is also a physical resource used by the user equipment. Of course, the predetermined rule can also be other ways, such as a physical resource included in the downlink control signaling having a fixed interval in the frequency domain is a physical resource allocated to the user equipment for use, which is not limited in the embodiment of the present invention.

[0353] The user equipment obtains all physical resources used to send or receive the data in HARQ mode through the downlink control signaling or the downlink control signaling and a predetermined rule, and uses all the physical resources to send or receive the data in parallel HARQ mode, wherein each physical resource corresponds to one HARQ transmission or reception.

[0354] Specifically, if there are at least two downlink control signalings, the at least two downlink control signalings may include all physical resources used by the user equipment, and may also include some physical resources used by the user equipment. Similarly, in the case where the downlink control signaling includes some physical resources among all physical resources, other physical resources used by the user equipment may be obtained through the physical resources included in the downlink control signaling and a predetermined rule.

[0355] Further, the physical resources included in each of the at least two downlink control signalings may be the same or different. For example, the user equipment receives two downlink control signalings, including downlink control signaling 1 and downlink control signaling 2, and uses two physical resources, namely physical resource 1 and physical resource 2, wherein each physical resource corresponds to a HARQ transmission or reception, and there are the following ways:

[0356] The first type: Downlink control signaling 1 includes physical resource 1, and downlink control signaling 2 includes physical resource 2, such as Figure 8 shown.

[0357] The second type: Downlink control signaling 1 includes physical resource 1 and physical resource 2, and downlink control signaling 2 includes physical resource 1 and physical resource 2, such as Fig. 9 shown.

[0358] The third type: Downlink control signaling 1 includes physical resource 1, downlink control signaling 2 includes physical resource 1, and the user equipment obtains physical resource 2 according to a predetermined rule, such as Fig.10 Of course, the downlink control signaling 1 may include the physical resource 2, the downlink control signaling 2 may include the physical resource 2, and the user equipment may obtain the physical resource 1 according to a predetermined rule.

[0359] In the embodiment of the present invention, the above-mentioned method in which each downlink control signaling in the at least one downlink control signaling includes at least one of all physical resources used by the user equipment to send or receive the data in a HARQ manner, and the user equipment uses all the physical resources to send or receive the data in a parallel HARQ manner, which can reduce signaling overhead compared to the traditional method of one signaling corresponding to one physical resource.

[0360] When the user equipment receives at least two downlink control signalings and the physical resources included in each downlink control signaling are the same, such as the second and third forms mentioned above, as long as the user equipment can successfully decode one downlink control signaling, it can obtain the physical resources used by the user equipment to send or receive the data in a parallel HARQ manner, thereby enhancing reliability.

[0361] Further, in order to further enhance the reliability of downlink control signaling transmission, when the user equipment receives at least two downlink control signalings and the physical resources included in each downlink control signaling are the same, the user equipment may combine and decode the at least two downlink control signalings. The specific execution process is as follows: Fig.11 As shown, including:

[0362] S401: User equipment receives HARQ configuration parameters.

[0363] S402: The user equipment receives at least one downlink control signaling.

[0364] The user equipment receives at least two downlink control signalings, and the physical resources included in each downlink control signaling are the same.

[0365] S403: The user equipment combines and decodes the at least two downlink control signalings.

[0366] S404: The user equipment uses all physical resources to send or receive the data in a parallel HARQ manner according to the HARQ configuration parameters and the physical resources included in the at least one downlink control signaling.

[0367] Optionally, before the user equipment in the embodiment of the present invention receives at least one downlink control signaling, the following steps are further included:

[0368] S402a: The user equipment receives a first carrier parameter, where the first carrier parameter is used to indicate a first carrier used by the user equipment to receive the at least one downlink control signaling.

[0369] Then, the user equipment receives at least one downlink control signaling, which can be specifically implemented in the following manner:

[0370] The user equipment receives the at least one downlink control signaling according to the first carrier indicated by the first carrier parameter.

[0371] The specific method flow chart including the step S402a in the embodiment of the present invention can be found in Fig.12 shown.

[0372] Optionally, before the user equipment sends or receives the data in a parallel HARQ manner, the following steps are further included:

[0373] S404a: The user equipment receives a second carrier parameter, where the second carrier parameter is used to indicate a second carrier used by the user equipment to send or receive the data in a parallel HARQ manner.

[0374] Then, the user equipment sends or receives the data in a parallel HARQ manner, which may be specifically in the following manner:

[0375] The user equipment sends or receives the data in a parallel HARQ manner according to the second carrier indicated by the second carrier parameter.

[0376] The specific method flow chart including the step S404a in the embodiment of the present invention can be found in Fig.13 shown.

[0377] Embodiments of the present invention Fig.13 A specific implementation scenario of the method execution process shown may include the following two scenarios:

[0378] The first scenario:

[0379] The second carrier indicated by the second carrier parameter is carrier 1, then the user equipment sends or receives the data in a parallel HARQ manner on carrier 1, and does not send or receive data in a parallel HARQ manner on other carriers, such as Fig.14 shown.

[0380] Second scenario:

[0381] The second carrier indicated by the second carrier parameter is carrier 1 and carrier 2, then the user equipment can send or receive the data in a parallel HARQ manner on carrier 1, carrier 2, or carrier 1 and carrier 2, and does not send or receive data in a parallel HARQ manner on other carriers, such as Fig.15 shown.

[0382] Optionally, in an embodiment of the present invention, the user equipment may also receive cross-carrier parameter information indicating whether to perform parallel HARQ across carriers. The cross-carrier parameter information is used to indicate whether the user equipment can send or receive data in a parallel HARQ manner on multiple carriers. If the user equipment receives cross-carrier parameter information indicating that the user equipment performs parallel HARQ across carriers, the user equipment sends or receives data in a parallel HARQ manner on multiple carriers. Otherwise, the user equipment sends or receives data in a parallel HARQ manner on one carrier.

[0383] In the embodiment of the present invention, when the user equipment is allowed to perform parallel HARQ, the multiple carriers may be licensed spectrum carriers, unlicensed spectrum carriers, or a mixture of licensed spectrum carriers and unlicensed spectrum carriers, which is not limited in the present invention.

[0384] It should be noted that the embodiments of the present invention Fig.12 In the method flow shown, the function of the first carrier parameter used to indicate the first carrier used for receiving downlink control signaling is similar to that of the second carrier parameter, which will not be described in detail herein.

[0385] In the embodiment of the present invention, the second carrier indicated by the second carrier parameter may be one or more than one. Further, when the second carrier is more than one, that is, includes at least two carriers, the following steps may be further included:

[0386] S404b: Receive indication information for configuring at least two subcarriers included in the second carrier as a virtual carrier.

[0387] Then, the user equipment sends or receives the data in a parallel HARQ manner according to the second carrier indicated by the second carrier parameter, and specifically adopts the following manner:

[0388] According to the indication information of configuring at least two subcarriers included in the second carrier as a virtual carrier, at least two subcarriers included in the second carrier are configured as a virtual carrier; and the data is sent or received in a parallel HARQ manner on the virtual carrier.

[0389] The specific method flow chart of the embodiment of the present invention including the above-mentioned S404b execution step can be found in Fig.16 shown.

[0390] Embodiments of the present invention Fig.16 A specific implementation scenario of the method execution process shown may be, for example:

[0391] When the user equipment receives the indication information that the carrier 1 and the carrier 2 are configured as a virtual carrier, the user equipment configures the carrier 1 and the carrier 2 as a virtual carrier, and sends or receives data in a parallel HARQ manner on the virtual carrier, such as Fig.17 shown.

[0392] In the embodiment of the present invention, the first carrier parameter, the second carrier parameter, the cross-carrier indication information, and the indication information for configuring the virtual carrier may be configured in the HARQ configuration parameters or in the downlink control signaling, which is not limited in the embodiment of the present invention.

[0393] Optionally, before the user equipment in the embodiment of the present invention receives the parallel HARQ communication indication, the method further includes the following steps:

[0394] S401a: The user equipment sends capability information for indicating that the user equipment supports sending or receiving the data in a parallel HARQ manner.

[0395] The specific method flow chart of the embodiment of the present invention including the above-mentioned S401a execution step can be found in Fig.18 shown.

[0396] In an embodiment of the present invention, the capability information sent by the user equipment to characterize that the user equipment supports sending or receiving the data in a parallel HARQ manner may be the capability of characterizing whether the user equipment supports sending or receiving the data in a parallel HARQ manner, or the capability of characterizing the number of parallel HARQs that the user equipment supports to send or receive the data in a parallel HARQ manner.

[0397] For example, the user equipment may send the capability of the user equipment to support sending or receiving data in M ​​parallel HARQ modes, where M is a positive integer, for example, M may be 1, 2, 3, 4, etc., to reflect that different user equipments have different parallel HARQ capabilities.

[0398] In an embodiment of the present invention, when the user equipment only sends a signal indicating whether the user equipment supports the capability of sending or receiving the data in a parallel HARQ manner, and does not send the number of parallel HARQs specifically supported by the user equipment, the number of parallel HARQs specifically supported by the user equipment can be specified by means such as protocol notification.

[0399] Optionally, the number of parallel HARQs supported by the user equipment in the embodiment of the present invention for sending or receiving the data in a parallel HARQ manner is specifically determined in the following manner:

[0400] The user equipment determines the number of carriers that can support carrier aggregation, and determines the determined number of carriers as the number of parallel HARQs supported by the user equipment for sending or receiving the data in a parallel HARQ manner.

[0401] In the embodiment of the present invention, the user equipment determines the number of parallel HARQs that the user equipment supports for sending or receiving the data in a parallel HARQ manner according to the supported carrier aggregation capability, which may specifically include the following application scenarios:

[0402] The first scenario:

[0403] The user equipment supports aggregation of carrier 1 and carrier 2, that is, the number of carriers supported by the user equipment for carrier aggregation is 2, and the number of parallel HARQs supported by the user equipment for sending or receiving the data in a parallel HARQ manner is 2, that is, the user equipment can support sending or receiving the data in a parallel HARQ manner with a HARQ number of 2 on carrier 1, carrier 2, carrier 1 and carrier 2, or other carriers except carrier 1 and carrier 2.

[0404] Second scenario:

[0405] The user equipment supports aggregation of carrier 3, carrier 4 and carrier 5, that is, the number of carriers supported by the user equipment for carrier aggregation is 3, then the number of parallel HARQs supported by the user equipment for sending or receiving the data in a parallel HARQ manner is 3, that is, the user equipment can send or receive the data in a parallel HARQ manner with a HARQ number of 3 on carrier 3, carrier 4, carrier 5, carrier 3+carrier 4+carrier 5, or other carriers except carrier 3, carrier 4 and carrier 5.

[0406] The third scenario:

[0407] The user equipment supports aggregation of carrier 1 and carrier 2, and also supports aggregation of carrier 3, carrier 4 and carrier 5, that is, the maximum number of carriers supported by the user equipment for carrier aggregation is 3, and the number of parallel HARQs supported by the user equipment for sending or receiving the data in parallel HARQ mode is 3, that is, the user equipment can send or receive the data in parallel HARQ mode with a HARQ number of 3 on any supported carrier or any multiple supported carriers.

[0408] Optionally, after the user equipment in the embodiment of the present invention sends and receives the data in a parallel HARQ manner, the method further includes the following steps:

[0409] S405: The user equipment sends feedback information through at least one uplink feedback resource, or receives feedback information through at least one downlink feedback resource.

[0410] The feedback information may include, for example, positive confirmation information and negative confirmation information, which is used to indicate whether the user equipment retransmits or receives the data.

[0411] The at least one uplink feedback resource is a transmission resource determined according to the physical resource used by the at least one downlink control signaling received by the user equipment. The at least one downlink feedback resource is a transmission resource determined according to the physical resource used by the user equipment to send or receive the data in a parallel HARQ manner. For example, an uplink feedback resource can be determined by each of the multiple downlink control signalings, which is equivalent to having multiple uplink feedback resources in total. Specifically, when there are multiple downlink control signalings, an uplink feedback resource is mapped out according to the position of the physical resource occupied by each downlink control signaling, such as CCE (Control Channel Element), and then uplink feedback is performed according to the multiple feedback resources; or, a downlink feedback resource is determined by each transmission resource of multiple uplink HARQ transmissions, which is equivalent to having multiple downlink feedback resources in total. Specifically, a downlink feedback resource is mapped out according to the position of the resource of each uplink HARQ transmission, such as PRB (Physical Resource Block), and then downlink feedback is performed according to the multiple feedback resources.

[0412] The specific method flow chart of the embodiment of the present invention including the above-mentioned S405 execution step can be found in Fig.19 shown.

[0413] Specifically, in the embodiment of the present invention, when the user equipment sends uplink data in a parallel HARQ manner, the user equipment can receive feedback information sent by a network device such as an eNB through at least one feedback resource to determine whether data retransmission is required. If the feedback information received by the user equipment is that the network device such as the eNB successfully received the uplink data, there is no need to resend the data. If the feedback information received by the user equipment is that the network device such as the eNB did not successfully receive the uplink data, the user equipment resends the data in a parallel HARQ manner.

[0414] Specifically, in the embodiment of the present invention, when the user equipment receives downlink data in a parallel HARQ manner, the user equipment can send feedback information to a network device such as an eNB through at least one feedback resource. When the user equipment successfully receives the downlink data, the user equipment delivers the data to a higher layer and sends a positive confirmation message to a network device such as an eNB, and does not need to receive the data again. When the user equipment fails to receive the data, it sends a negative confirmation message to a network device such as an eNB, and needs to receive the data again.

[0415] Optionally, in an embodiment of the present invention, feedback information may be sent or received via at least two feedback resources to improve feedback reliability.

[0416] It should be noted that, in the embodiment of the present invention, the specific number of feedback resources used to send feedback information may be in the form of protocol notification or in the form of HARQ configuration parameter configuration, which is not limited in the embodiment of the present invention.

[0417] In another embodiment of the present invention, the execution subject of the communication method for sending or receiving data in parallel HARQ mode is a network device, that is, the communication device involved in the embodiment of the present invention is a network device.

[0418] When the communication device is a network device, the implementation process of the communication method for sending or receiving data in a parallel HARQ manner provided by the embodiment of the present invention is similar to the implementation process of the above-mentioned execution subject being a user device, except that the network device does not involve receiving downlink control signaling, and based on the information included in the downlink control signaling, implements the parallel HARQ method to send or receive data. Therefore, the implementation process of the communication method when the communication device is a network device will not be repeated here, and reference may be made to the implementation method when the execution subject is a user device.

[0419] Fig. 20 FIG. 1 is a flow chart showing another implementation method of a communication method provided by an embodiment of the present invention. Fig. 20 The method shown is performed by a network device, such as Fig. 20 As shown, including:

[0420] S501: The network device determines a parallel HARQ communication indication.

[0421] The parallel HARQ communication indication in the embodiment of the present invention is used to instruct the user equipment to send or receive data in a parallel HARQ manner, wherein sending data in a parallel HARQ manner means sending at least one data packet with the same content within the same transmission time interval, and receiving data in a parallel HARQ manner means receiving at least one data packet with the same content within the same transmission time interval, and merging and decoding the at least one received data packet with the same content.

[0422] The network device in the embodiment of the present invention can be an evolved base station (eNB) in the LTE system, a base station (NodeB) in the Universal Mobile Telecommunications System (UMTS), or other network devices that communicate with user equipment and perform resource configuration and scheduling for the user equipment, which is not limited in the embodiment of the present invention.

[0423] S502: The network device sends the parallel HARQ communication indication to the user equipment.

[0424] In the embodiment of the present invention, the network device may send the parallel HARQ communication indication via a Radio Resource Control (RRC) message, such as a system message, or a dedicated RRC message, such as an RRC connection reconfiguration message. Of course, the embodiment of the present invention is not limited thereto, and may also be received via a physical layer message or a media access control (MAC) layer message.

[0425] In the embodiment of the present invention, the network device sends a parallel HARQ communication indication to the user equipment, so that the user equipment can send or receive data in a parallel HARQ manner according to the parallel HARQ communication indication, and send or receive at least one data packet with the same content within the same transmission time interval, thereby realizing parallel sending or receiving of data packets, which can reduce latency, and the sending or receiving of multiple data packets within the same transmission time also improves the reliability of data transmission.

[0426] Optionally, the parallel HARQ communication indication determined by the network device in the embodiment of the present invention may be a HARQ configuration parameter. The HARQ configuration parameter is a configuration parameter for the user equipment to send or receive the data in a parallel HARQ manner.

[0427] In the embodiment of the present invention, the HARQ configuration parameters used as parallel HARQ communication indications may be set to include different configuration parameters according to actual conditions. For example, in the embodiment of the present invention, the HARQ configuration parameters may include parameter information such as the number of parallel HARQ parameters for the user equipment to send or receive data in a parallel HARQ manner, carrier information used to indicate the user equipment to send or receive data in a parallel HARQ manner, feedback resource information, etc., which is not limited in the embodiment of the present invention.

[0428] In an optional manner in an embodiment of the present invention, a parallel HARQ number parameter is included in the HARQ configuration parameter, and the parallel HARQ number parameter includes the maximum number of parallel HARQs executed by the user equipment each time the user equipment sends or receives the data, or the specific number of parallel HARQs.

[0429] In an embodiment of the present invention, when the parallel HARQ number parameter includes the maximum number of parallel HARQs, other signaling notification methods, such as downlink control signaling notification methods, may be used to notify the specific number of parallel HARQs currently being performed for the data sending or receiving, thereby reducing the overhead of physical channel resources and allowing the user equipment to use a different number of parallel HARQs each time it sends or receives the data, so as to dynamically adapt to changes in channel conditions and ensure low latency and high reliability of data sending or receiving.

[0430] It should be noted that, in the embodiment of the present invention, the HARQ configuration parameters may include uplink HARQ configuration parameters and downlink HARQ configuration parameters, and the uplink HARQ configuration parameters indicate the configuration parameters required for the user equipment to send the data in a parallel HARQ manner, and the downlink HARQ configuration parameters indicate the configuration parameters required for the user equipment to receive the data in a parallel HARQ manner. Of course, the embodiment of the present invention is not limited to the above manner.

[0431] In the embodiment of the present invention, the HARQ configuration parameter is used as a parallel HARQ communication indication, so that the user equipment sends or receives data in a parallel HARQ manner according to the received HARQ configuration parameter. The parallel HARQ manner can be used to send or receive data with less signaling overhead, reduce latency, and improve reliability.

[0432] Optionally, the network device in an embodiment of the present invention may be configured with at least one downlink control signaling, wherein the at least one downlink control signaling includes information such as physical resources, modulation and coding methods, and parallel HARQ number parameters used by the user equipment to send or receive the data in a parallel HARQ manner.

[0433] The embodiment of the present invention is Fig. 20 On the basis of the method flow shown in FIG. 1 , at least one downlink control signaling configured may also be sent to the user equipment to notify the user equipment through the downlink control signaling of information such as the physical resources, modulation and coding mode, and parallel HARQ number parameters used to send or receive the data in a parallel HARQ manner, such as Fig.21 As shown, it also includes:

[0434] S503: The network device configures at least one downlink control signaling.

[0435] The at least one downlink control signaling includes information such as physical resources, modulation and coding methods, and parallel HARQ number parameters used by the user equipment to send or receive the data in a parallel HARQ manner. In the embodiment of the present invention, the information specifically included in the downlink control signaling can be adaptively changed in combination with the content included in the configuration parameters. The information included in the HARQ configuration parameters does not need to be notified through the downlink control signaling. For example, the parallel HARQ number parameter included in the downlink control signaling can be the maximum number of parallel HARQs executed by the user equipment each time it sends or receives the data, or it can be the specific number of parallel HARQs. If the specific number of parallel HARQs executed by the user equipment each time it sends or receives the data is already included in the HARQ configuration parameters, the specific number of parallel HARQs does not need to be included in the downlink control signaling.

[0436] Optionally, each downlink control signaling in the at least one downlink control signaling includes at least one of all physical resources used by the user equipment to send or receive the data in a parallel HARQ manner.

[0437] Specifically, all physical resources refer to a set of physical resources used by each HARQ transmission or reception when the data is sent or received in a parallel HARQ manner.

[0438] Specifically, if the downlink control signaling is one, the downlink control signaling may include all physical resources used by the user equipment, or may include some physical resources among all physical resources used by the user equipment. In the case where the downlink control signaling includes some physical resources among all physical resources, other physical resources used by the user equipment may be obtained through the physical resources included in the downlink control signaling and a predetermined rule.

[0439] Specifically, if there are at least two downlink control signalings, the at least two downlink control signalings may include all physical resources used by the user equipment, and may also include some physical resources used by the user equipment. Similarly, in the case where the downlink control signaling includes some physical resources among all physical resources, other physical resources used by the user equipment may be obtained through the physical resources included in the downlink control signaling and a predetermined rule.

[0440] Optionally, there are at least two downlink control signalings, and the physical resources included in each downlink control signaling are the same.
