Description

Method for transmitting data in TDD network using TTI Bundling technology and user equipment supporting TTI Bundling technology in TDD network

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for transmitting data in a TDD network using a TTI Bundling technique and a user equipment supporting the TTI Bundling technique in the TDD network.

Background

In a Long Term Evolution (LTE) system, according to the usage of different time-frequency resources, the LTE system can be divided into an LTE TDD (time division duplex) system and an LTE FDD (frequency division duplex) system.

In the LTE TDD system, there are various uplink and downlink subframe ratios. As shown in table 1, the LTE TDD system can support seven different uplink and downlink subframe allocations, i.e., uplink and downlink allocations 0 to 6, where each uplink and downlink allocation corresponds to a structure of a radio frame (english: frame). Each radio frame includes 10 subframes (english: sub-frames), subframe indexes may also be referred to as subframe numbers, and the subframe indexes are circularly numbered from 0 to 9, for example, the subframe index of the 1 st subframe is 0, and the subframe index of the 11 th subframe is 0. Each subframe includes 2 slots (english: slot), each slot also corresponds to a slot number, and the slot numbers are circularly numbered from 0 to 19, for example, the slot number of the first slot corresponding to the subframe number 1 is 2, the slot number of the second slot corresponding to the subframe number is 3, the slot number of the first slot corresponding to the subframe number 11 is 2, and the slot number of the second slot corresponding to the subframe number is 3. Each subframe has a corresponding subframe type, and the subframe type can be an uplink subframe, a downlink subframe or a special subframe.

TABLE 1

As shown in table 1, D denotes that the subframe is a downlink subframe, S denotes that the subframe is a special subframe, and U denotes that the subframe is an uplink subframe. The downlink subframe is used for downlink transmission, the Uplink subframe is used for Uplink transmission, and the special subframe is composed of three parts, namely a downlink Pilot Time Slot (DwPTS), a Guard Period (GP), and an Uplink Pilot Time Slot (UpPTS).

In order to improve the transmission quality of uplink data of user equipment on an uplink between the user equipment and a base station, a transmission time interval Bundling (TTI Bundling for short) technology and a frequency hopping (hopping) technology are proposed.

The main idea of the TTI Bundling technique is to encode a data packet to form a plurality of different redundancy versions, and transmit the data packets of the plurality of different redundancy versions in a plurality of consecutive uplink subframes, respectively. The consecutive subframes form a Transmission Time Interval (TTI) packet, and transmission using the TTI packet may be referred to as TTI packet transmission. In the LTE system, a subframe corresponds to a Transmission Time Interval (TTI) in terms of time length, and thus, it can also be expressed that one TTI Bundle consists of a plurality of TTIs. The number of TTIs contained in a TTI Bundle may be specified by a parameter TTI _ Bundle _ SIZE, which is specified as 4 in the LTE system, i.e. one TTI Bundle comprises 4 TTIs. After the transmission of one TTI Bundle is completed, the base station feeds back an ACK/NACK for the transmission of the TTI Bundle, instead of feeding back an ACK/NACK for each TTI in one TTI Bundle. When transmission of one TTI Bundle fails, the next TTI Bundle may be used for retransmission. For the initial transmission and the retransmission of the TTI Bundle of the same packet, the same hybrid automatic repeat request (HARQ) process is used to process the initial transmission and the retransmission of the TTI Bundle of the same packet.

In an LTE TDD system, when an uplink and downlink ratio of 0,1 or 6 is adopted, a TTI Bundling technique may be supported. In the LTE TDD system, one TTI Bundle is composed of 4 consecutive uplink subframes. In the LTE TDD system, consecutive uplink subframes do not represent that the uplink subframes are consecutive in time. For example, in uplink/downlink ratio 0 of table 1, subframes 2,3,4, and 7 are consecutive uplink subframes, but subframe 4 and subframe 7 are not consecutive in time.

The main idea of the frequency hopping technique is to use different frequency resources for two different time slots of the same subframe, or to use different frequency resources for different subframes, to obtain frequency diversity gain. For the time-frequency resource, from the perspective of the frequency domain, the frequency-domain resource can be divided into different Resource Blocks (RBs), so that each RB corresponds to a frequency-domain position, that is, the frequency-domain position can be expressed by using the number of the RB. Since an RB may be generally referred to as a Physical Resource Block (PRB), the frequency domain position may be represented by the number of the PRB. The uplink bandwidth generally refers to a frequency domain size of a time-frequency resource for uplink transmission, and may be represented by the number of RBs included in a frequency domain. For example, the uplink bandwidth is 50 RBs. Among these RBs, a part of the RBs is used for transmission of PUCCH and another part of the RBs is used for transmission of PUSCH, where the number of RBs used for transmission of PUSCH is called a hopping bandwidth, that is, uplink data transmission can be hopped among the RBs used for transmission of PUSCH. In the LTE system, there are two hopping types, one is type one (english: type1) and the other is type two (english: type 2). The main idea of Type1 frequency hopping is to cyclically shift several RBs in the high frequency direction on the basis of the original RB, i.e. frequency hopping from the original frequency domain position to the target frequency domain position is realized. The main idea of Type2 frequency hopping is to divide the frequency domain resource for the transmission of PUSCH into multiple equal bandwidth sub-bands (English: subband) and cyclically shift several sub-bands based on the original RB. Wherein each sub-band comprises a plurality of consecutive RBs, and the number of RBs comprised by the sub-band can be configured by the base station. In addition, the Type2 frequency hopping further supports a mirror image function, and is used for performing mirror image mapping on the frequency domain based on the center position of the sub-band where the frequency domain position obtained after shifting is located on the basis of circularly shifting several sub-bands to obtain the mirror image mapped frequency domain position.

Currently, how to correctly apply frequency hopping technology to the TTI Bundle of an LTE TDD network is used for a problem to be solved.

According to the method and the user equipment provided by the embodiment of the invention, the frequency domain positions corresponding to the rest subframes in the TTI Bundle are kept consistent with the frequency domain positions corresponding to the first subframe in the TTI Bundle or the frequency domain positions corresponding to the first subframe after frequency hopping of the first subframe of the TTI Group in the TTI Bundle, so that frequency hopping between TTI bundles in a TDD network or between and in the TTI Bundle is realized, and therefore, better frequency gain can be obtained. The frequency hopping scheme is compatible with the existing frequency hopping scheme of non-TTI Bundle frequency hopping, so that the implementation complexity of the frequency hopping of the TTI Bundle of the TDD system is reduced.

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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 network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

For convenience of understanding, the embodiment of the present invention is described by taking an LTE TDD network defined by 3GPP as an example. Third generation partnership project (English: 3)^rdgeneration partnership project, 3GPP for short) is a project that is dedicated to the development of wireless communication networks. The LTE TDD network in the embodiments of the present invention complies with the 3GPP standard, except where specifically noted in the embodiments. Those skilled in the art will appreciate that the solution of the embodiments of the present invention may be applied to other TDD networks.

Fig. 1 shows an LTE TDD network. For convenience of describing the solution of the embodiment of the present invention, the network in fig. 1 only shows the user equipment 101 and the base station 102, and those skilled in the art should understand that other devices exist in the actual network. The ue 101 is located in a coverage area of the base station 102, and may perform service transmission with the base station through a wireless air interface technology. Generally, data transmission from the user equipment to the base station may be referred to as uplink transmission, and data transmitted in uplink may be referred to as uplink data. Uplink data is typically transmitted on the PUSCH.

As can be understood by those skilled in the art, a User Equipment (UE) is a terminal device, and may be a mobile terminal device or an immobile terminal device. The device is mainly used for receiving or sending service data. The user equipments may be distributed in networks where the user equipments have different names, such as: a terminal, mobile station, subscriber unit, station, cellular telephone, personal digital assistant, wireless modem, wireless communication device, handheld device, laptop computer, cordless telephone, wireless local loop station, or the like.

For example, the structure of the user equipment 101 may be as shown in fig. 2. As shown in fig. 2, the user equipment 101 includes a processing unit 201 and a transceiving unit 202. The processing unit 201 is generally configured to process data, instructions, and the like, and the transceiver unit 202 is generally configured to receive or transmit information through an air interface technology. As an alternative embodiment, the functions of the processing unit 201 may be integrated in the processor, and implemented by the processor. The processor may be, for example, a general-purpose processor, or a special-purpose processor; the functions of the transceiver unit 202 may be implemented by a transceiver. As another alternative, a set of instructions to implement the functions of the processing unit 201 and the transceiver unit 202 may be stored in a storage medium, and read and executed by a processor to implement the functions of the processing unit 201 and the transceiver unit 202.

As will be understood by those skilled in the art, a Base Station (BS), also referred to as a base station device, is a device deployed in a radio access network for providing wireless communication functions. For example, the device providing the base station function in the LTE network includes an evolved node B (eNB or eNodeB), the device providing the base station function in the 2G network includes a Base Transceiver Station (BTS) and a Base Station Controller (BSC), and the device providing the base station function in the 3G network includes a node B (NodeB) and a Radio Network Controller (RNC).

Illustratively, the structure of the base station 102 may be as shown in fig. 3. As shown in fig. 3, the base station 102 includes a processing unit 301 and a transceiving unit 302. The processing unit 301 is generally configured to process data, instructions, and the like, and the transceiver unit 302 is generally configured to receive or transmit information through an air interface technology. As an alternative implementation, the functions of the processing unit 301 may be integrated into a processor or a processing board, and the processor or the processing board implements the functions. For example, the processor may be a general-purpose processor or a special-purpose processor, and the processing board is a board with signaling and data processing functions; the functions of the transceiver unit 302 may be implemented by a transceiver. As another alternative, a set of instructions implementing the functionality of the processing unit 301 and the transceiver unit 302 may be stored in a storage medium and read and executed by a processor to implement the functionality of the processing unit 301 and the transceiver unit 302.

In the LTE TDD network shown in fig. 1, it is assumed that the uplink and downlink ratio configured by the network is uplink and downlink ratio 0, and the SIZE of the TTI Bundle (the small TTI Bundle can be represented by the parameter TTI _ Bundle _ SIZE) is 4. Those skilled in the art should understand that the solution of the embodiment of the present invention can also be applied to other uplink and downlink allocations and other scenarios of TTI Bundle size.

TABLE 2

As shown in table 2, when the uplink/downlink ratio is 0, uplink subframes 2,3,4, and 7 of radio frame #1 form a TTI Bundle, which is labeled as TTI Bundle # 1-1; uplink subframes 8 and 9 of the radio frame #1 and uplink subframes 2 and 3 of the radio frame #2 form a TTI Bundle, and the TTI Bundle is marked as TTI Bundle # 2-1; uplink subframes 4,7,8 and 9 of radio frame #2 form a TTI Bundle, which is labeled as TTI Bundle # 3-1. Uplink subframes 2,3,4 and 7 of the radio frame #3 form a TTI Bundle marked as TTI Bundle #1-2, uplink subframes 8 and 9 of the radio frame #3 and uplink subframes 2 and 3 of the radio frame #4 form a TTI Bundle marked as TTI Bundle # 2-2; uplink subframes 4,7,8, and 9 of radio frame #4 constitute a TTI Bundle, labeled TTI Bundle # 3-2. Those skilled in the art will appreciate that for ease of description, table 2 only lists the first 40 subframes, and that more TTI bundles exist in an actual network environment.

When the uplink and downlink ratio is 0, there are 3 HARQ processes, which are respectively labeled as HARQ #1, HARQ #2 and HARQ # 3. Therefore, HARQ #1 can transmit data in TTI Bundle #1-1, HARQ #2 can transmit data in TTI Bundle #2-1, and HARQ #3 can transmit data in TTI Bundle # 3-1. If the transmission of the first TTI Bundle fails, HARQ #1 may use TTI Bundle #1-2 to perform the retransmission of the first TTI Bundle, HARQ #2 may use TTI Bundle #2-2 to perform the retransmission of the first TTI Bundle, and HARQ #2 may use TTI Bundle #3-2 to perform the retransmission of the first TTI Bundle.

For ease of understanding, the scheme of the embodiment of the present invention will be described below by taking HARQ #1 as an example.

In order to realize frequency hopping of TTI Bundle in TDD network, the embodiment of the invention provides two frequency hopping modes of TTI Bundle.

The first frequency hopping mode of TTI Bundle is inter-Bundle hopping (english), that is, for transmission of two adjacent TTI bundles of the same HARQ process, different frequency domain resources (different frequency domain resources can be understood to have different frequency domain positions in the frequency domain) are used, and subframes in the same TTI Bundle use the same frequency domain resource. For example, in the inter-TTI Bundle frequency hopping mode, for HARQ #1, the frequency domain resource f1 is used for transmission of TTI Bundle #1-1, the frequency domain resource f2 is used for transmission of TTI Bundle #1-2, the frequency domain resource f1 is corresponding to the sub-frame in TTI Bundle #1-1, and the frequency domain resource f2 is corresponding to the sub-frame in TTI Bundle # 1-2.

The second frequency hopping mode of TTI Bundle is intra-and inter-TTI Bundle frequency hopping (english: intra-and inter-Bundle hopping), that is, for transmission of one TTI Bundle of the same HARQ process, subframes in the TTI Bundle use different frequency domain resources. For example, for TTI Bundle #1-1, subframes 2 and 3 correspond to frequency domain resource f3, and subframes 4 and 7 correspond to frequency domain resource f4, or subframes 2,3, and 4 correspond to frequency domain resource f5, and subframe 7 corresponds to frequency domain resource f 6. It can be seen that in order to realize intra and inter-Bundle hopping, the subframes of TTI Bundle #1-1 need to be grouped, and such grouping of subframes can be referred to as TTI Group. Regarding the grouping manner, the embodiment of the present invention proposes 2 methods. In the first grouping method, the number of subframes included in each group (which may also be referred to as a group size) may be specified by the network, and the group size may be configured by the base station to the user equipment or may be predetermined. For example, when the packet size is 2, the TTI Bundle #1 may be divided into 2 TTI groups, one TTI Group #1 including subframes 2 and 3, and the other TTI Group #2 including subframes 4 and 7. In the second grouping method, the subframes in the TTI Bundle may be grouped into a group according to whether the subframes are grouped in the time domain continuously. For example, for TTI Bundle #1-1, subframes 2,3, and 4 are contiguous in the time domain, and subframe 7 is non-contiguous in the time domain with subframe 4, so subframes 2,3, and 4 may form a TTI Group, and subframe 7 forms a TTI Group. It can be seen that one TTI Group may include one or more subframes, different TTI groups are not consecutive in the time domain, and if one TTI Group includes multiple subframes, the subframes are consecutive in the time domain. Therefore, for intra and inter-Bundle hopping, in one TTI Bundle, two adjacent TTI groups use different frequency domain resources, and subframes in the same TTI Group use the same frequency domain resources, for example, f7 for TTI Group #1 and f8 for TTI Group #2, so that intra and inter-Bundle hopping can be achieved.

Illustratively, which frequency hopping pattern the user equipment should use may be configured by the base station. For example, the base station may send an indication message to the ue indicating that the ue is using inter-bundle hopping or intra-and inter-bundle hopping. Optionally, the UE may set one of the frequency hopping modes when the UE leaves the factory, so that the UE only supports one frequency hopping mode, and when frequency hopping is needed, the UE may report its own frequency hopping mode to the base station.

For inter-Bundle hopping, how to determine the frequency domain resource corresponding to each TTI Bundle, that is, how to determine the frequency domain position corresponding to the TTI Bundle, the embodiment of the present invention proposes that the frequency domain position corresponding to the first subframe in the TTI Bundle is determined by determining the frequency domain position corresponding to the first subframe, that is, the frequency domain position corresponding to the first subframe in the TTI Bundle is also used as the frequency domain position corresponding to other subframes in the TTI Bundle, so that the entire TTI Bundle corresponds to one frequency domain position.

For intra and inter-bundle hopping, how to determine the frequency domain resource corresponding to each TTI Group, that is, how to determine the frequency domain position corresponding to the TTI Group, the embodiment of the present invention proposes that the frequency domain resource corresponding to the first subframe in the TTI Group is determined by determining the frequency domain corresponding to the first subframe, that is, the frequency domain position corresponding to the first subframe in the TTI Group is also used as the frequency domain position corresponding to other subframes in the TTI Group, so that the whole TTI Group corresponds to one frequency domain position.

Regarding how to determine the frequency domain position corresponding to the first subframe in the TTI Bundle, the embodiment of the present invention provides two frequency hopping methods to determine the frequency domain position corresponding to the first subframe.

The idea of the first frequency hopping method is to associate the frequency domain position corresponding to the first subframe in the TTI Bundle with the current transmission times of the TTI Bundle. In the embodiment of the present invention, the first frequency hopping scheme is called type one (type 1). The current transmission times of the TTI Bundle refer to the times of transmitting the same data packet by using the TTI Bundle for the same HARQ process, for example, the HARQ #1 transmits the data packet a in the TTI Bundle #1-1, the current transmission times may be counted as 1, if the transmission fails, the data packet a is retransmitted in the TTI Bundle #1-2, and the current transmission times may be counted as 2. When the current transmission frequency is an even number, the frequency domain position corresponding to the first subframe in the TTI Bundle may be set to be equal to the first frequency domain position, and when the current transmission frequency is an odd number, the frequency domain position corresponding to the first subframe in the TTI Bundle may be set to be equal to the second frequency domain position. Of course, the frequency domain position corresponding to the first subframe in the TTI Bundle may be set to be equal to the first frequency domain position when the current transmission frequency is odd, and the frequency domain position corresponding to the first subframe in the TTI Bundle may be set to be equal to the second frequency domain position when the current transmission frequency is even.

For example, the first frequency domain position may be determined according to an indication of the base station, that is, the base station sends indication information to the user equipment to inform the user equipment of the first frequency domain position. After the first frequency domain location is known, the second frequency domain location can be determined according to one of the following 3 equations.

Wherein n is_PRBThe number of the Resource Blocks (RBs) occupied by the Physical Uplink Shared Channel (PUSCH) in the frequency domain is the second frequency domain position, the first frequency domain position, and the number of the RBs occupied by the Physical Uplink Control Channel (PUCCH) in the frequency domain.

In order to reduce implementation complexity, a mapping relationship between the first frequency domain location and the second frequency domain location may be configured on the user equipment, and the mapping relationship satisfies one of the above 3 formulas. The user equipment can determine the second frequency domain position by means of table lookup instead of calculating the second frequency domain position according to the formula each time.

For example, the base station may also determine a second frequency domain position according to the first frequency domain position, so as to receive uplink data sent by the user equipment at the second frequency domain position.

For example, which formula of the above 3 formulas should be selected may be indicated by the base station through the indication information to instruct the user equipment to select the corresponding formula. For example, the base station sends information of two bits to the ue, where 00 represents formula (1), 01 represents formula (2), and 03 represents formula (3).

The idea of the second frequency hopping method is to associate the frequency domain position corresponding to the first subframe in the TTI Bundle with the slot number of the first subframe including one of two slots. In the embodiment of the present invention, the second frequency hopping scheme is called type two (type 2). Wherein, in the LTE system, one subframe includes two slots, and the slot number of any one slot can be selected here.

The frequency domain position of the time frequency resource corresponding to the first subframe meets the following formula:

wherein n is_PRBThe frequency domain position, N, of the time-frequency resource corresponding to the first subframe_sbNumber of subbands, number of RBs included for said subbands, n_VRBNumber of RBs occupied by PUCCH in frequency domain, or n, for virtual frequency domain position_sIs the slot number, N, of the first subframe_TXIs the current transmission times of the TTI Bundle, f_hop(i) Is the firstSub-band offset, f, corresponding to a sub-frame_m(i) And the mirror image value is the mirror image value corresponding to the first subframe. Wherein f is_hop(i) And f_m(i) The meaning and calculation method of (a) are consistent with the existing LTE TDD network, and are not described herein. In the formula (4), if the slot numbers of the two slots included in the first subframe of two different TTI bundles are the same, then they are different, or for example: the first subframe 2 of TTI Bundle #1-1 and the first subframe 22 of TTI Bundle #1-2 have the same slot number of the slot, and i corresponding to subframe 2 is different from i corresponding to subframe 22, so the frequency domain position corresponding to subframe 2 is also different from the frequency domain position corresponding to subframe 22.

In order to reduce implementation complexity, a mapping relationship between the first frequency domain location and the second frequency domain location may be configured on the user equipment, and the mapping relationship satisfies the above equation (4). The user equipment can determine the second frequency domain position by means of table lookup instead of calculating the second frequency domain position according to the formula each time.

For example, the virtual frequency domain position may be sent to the user equipment by the base station through indication information, that is, the base station sends indication information to the user equipment, where the indication information is used to indicate the virtual frequency domain position.

For example, the number of subbands may be sent to the user equipment by the base station through indication information, that is, the base station sends indication information to the user equipment, where the indication information is used to indicate the number of subbands. In the LTE system, the base station may inform all the user equipments in the cell of the above subband number through SIB2 message.

For example, as to how to select the frequency hopping pattern, the base station may instruct the user equipment through indication information, that is, the base station sends the indication information to the user equipment, which indicates that the frequency hopping pattern adopted by the user equipment is type1 or type 2.

Regarding how to determine the frequency domain position corresponding to the first subframe in the TTI Group, the embodiment of the present invention provides two frequency hopping manners to determine the frequency domain position corresponding to the first subframe, similar to determining the frequency domain position corresponding to the first subframe of the TTI Bundle.

The idea of the first frequency hopping scheme is to associate the frequency domain position corresponding to the first subframe in the TTI Group with the sequence number of the TTI Group to which the first subframe belongs. In the embodiment of the present invention, the first frequency hopping scheme is called type one (type 1). The number of the TTI Group may be numbered from 0 or 1. When the sequence number of the TTI Group is an even number, the frequency domain position corresponding to the first subframe in the TTI Group may be set to be equal to the first frequency domain position, and when the sequence number of the TTI Group is an odd number, the frequency domain position corresponding to the first subframe in the TTI Group may be set to be equal to the second frequency domain position. Of course, the frequency domain position corresponding to the first subframe in the TTI Group may be set to be equal to the first frequency domain position when the sequence number of the TTI Group is odd, and the frequency domain position corresponding to the first subframe in the TTI Group may be set to be equal to the second frequency domain position when the sequence number of the TTI Group is even.

For example, the first frequency domain position may be determined according to an indication of the base station, that is, the base station sends indication information to the user equipment to inform the user equipment of the first frequency domain position. After the first frequency domain position is known, the second frequency domain position may be determined according to one of the above equations (1), (2) and (3), which is not described herein again.

The idea of the second frequency hopping method is to associate the frequency domain position corresponding to the first subframe in the TTI Group with the slot number of the first subframe including one of two slots. In the embodiment of the present invention, the second frequency hopping scheme is called type two (type 2). Wherein, in the LTE system, one subframe includes two slots, and the slot number of any one slot can be selected here.

The frequency domain position of the time-frequency resource corresponding to the first subframe satisfies the formula (4), and details about the formula (4) are not repeated herein.

In order to better understand the solution of the embodiment of the present invention, it will be explained by an example shown in fig. 4.

401: the base station 102 transmits the frequency hopping configuration information to the user equipment 101.

As an alternative, the transceiver unit 302 of the base station 102 may send the frequency hopping configuration to the user equipment 101.

As an alternative, the transceiver unit 202 of the user equipment 101 may receive the frequency hopping configuration transmitted by the base station 102.

402: the user equipment 101 determines the frequency domain position of the time-frequency resource corresponding to one subframe according to the frequency hopping configuration information;

as an alternative embodiment, the processing unit 201 of the user equipment 101 may be configured to determine a frequency domain location of a time-frequency resource corresponding to one subframe.

As an optional implementation manner, the processing unit 301 of the base station apparatus 102 may be configured to determine a frequency domain location of a time-frequency resource corresponding to one subframe.

403: the user equipment 101 sends a data packet to the base station 102 on a time-frequency resource corresponding to a current subframe;

as an optional implementation manner, the transceiver unit 202 of the user equipment 101 may be configured to send data to the base station 102 through the determined time-frequency resource corresponding to one subframe.

In step 403, the base station 102 may receive the data packet sent by the ue 101 on the corresponding time-frequency resource.

As an optional embodiment, the transceiver unit of the base station 102 may be configured to receive, through the determined time-frequency resource corresponding to one subframe, a data packet sent by the user equipment 101 in the time-frequency resource.

The base station 102 may send the frequency hopping configuration information to the user equipment 101 through one or more of a system broadcast message, downlink control information (downlink control information), SIB2 message, and uplink Grant (UL Grant).

As an example, in step 401, the frequency hopping configuration transmitted by the base station 102 to the user equipment 101 is as follows:

parameter 1: frequency hopping mode: inter-bundle hopping

Parameter 2: the frequency hopping formula: formula (1)

Parameter 3: first frequency domain position: n1

Those skilled in the art will understand that the indication information indicating the frequency hopping formula is carried in the frequency hopping configuration here, which is exactly equal to what kind of frequency hopping type is indicated, i.e. type1 or type 2.

Accordingly, in step 402, the ue 101 sends data to the base station 102 in subframe 2 of TTI Bundle #1-1, and knows that the number of transmission times of the current TTI Bundle is 1, and if the number of transmission times is odd, the ue sets the frequency domain position corresponding to the first subframe in the TTI Bundle to be equal to the first frequency domain position indicated by the base station, so that the ue determines that the frequency domain position corresponding to the current subframe 2 is N1, and sends data in the frequency domain position in step 403. For subframes 3,4, and 7, the ue 101 may determine that the frequency domain positions corresponding to subframes 3,4, and 7 are the frequency domain position of subframe 2, that is, may send the data packet to the base station 102 at frequency domain position N1. If the data transmitted by the ue 101 in TTI Bundle #1-1 is not correctly received by the bs 102, the ue 101 retransmits the data in TTI Bundle # 1-2. The first subframe of TTI Bundle #1-2 is subframe 2, and for subframe 2, the ue knows that the transmission frequency of the current TTI Bundle is 2, and assumes that the frequency domain position corresponding to the first subframe in the TTI Bundle is set to be equal to the second frequency domain position when the current transmission frequency is even, and the second frequency domain position is determined according to the first frequency domain position and formula (1), at this time, the ue 101 obtains the second frequency domain position N2 according to formula (1) and the first frequency domain position N1, and sends data to the base station 102 at the frequency domain position N2 in step 403. For other subframes 3,4, and 7 of TTI Bundle #1-2, the ue 101 may determine that the frequency domain positions corresponding to subframes 3,4, and 7 of TTI Bundle #1-2 are the same as the frequency domain position corresponding to subframe 2 of TTI Bundle #1-2, i.e., transmit data to the bs 102 at frequency domain position N2. The second frequency domain position may also be determined by the same method for the base station 102, so that the base station 102 may receive the data transmitted by the user equipment 101 at the second frequency domain position N2. The frequency hopping results of this example are shown in FIG. 5, where TTI Bundle #1-1 is data transmitted at frequency domain position N1, and TTI Bundle #1-2 is data transmitted at frequency domain position N2.

Those skilled in the art will appreciate that equation (1) in the above described frequency hopping configuration may also be replaced with equation (2), or equation (3), or equation (4). When formula (4) is substituted, the above frequency hopping configuration may further include parameter 4: the number of subbands, parameter 3, may be a virtual frequency domain position. It will be appreciated by those skilled in the art that the different parameters in the above described hopping configuration may be sent in one message or in different messages.

As another example, in step 402, the frequency hopping configuration transmitted by the base station 102 to the user equipment 101 is as follows:

parameter 1: frequency hopping mode: intra and inter-bundle hopping

Parameter 2: the frequency hopping formula: formula (4)

Parameter 3: virtual frequency domain position: VN3

Parameter 4: number of subbands: 2

Parameter 5: the number of sub-frames in TTI Group is 2

Those skilled in the art will understand that the parameter 2 in the frequency hopping configuration indicates the frequency hopping formula (4), which in fact implicitly indicates the frequency hopping pattern as type 2. Similarly, if the parameter 2 indicates the frequency hopping formula (1) or (2) or (3), the frequency hopping pattern is implicitly indicated as type 1.

It will be appreciated by those skilled in the art that the parameter 5 here indicates the first grouping method described above. Optionally, the parameter 5 may also indicate the second grouping method described above. Alternatively, if no grouping method is indicated in the hopping configuration, the user equipment 101 may default to the second grouping method.

Accordingly, in step 402, the user equipment 101 determines the frequency domain location corresponding to the subframe. Specifically, the ue 101 transmits data to the base station 102 in TTI Bundle # 1-1. According to parameter 5, TTI Bundle #1-1 will be divided into two TTI groups, one TTI Group #1 and the other TTI Group #2, TTI Group #1 comprising subframes 2 and 3 and TTI Group #2 comprising subframes 4 and 7. For subframe 2, since subframe 2 is the first subframe of TTI Group #1, the frequency domain position N3 corresponding to subframe 2 can be obtained through formula (4), and therefore, the ue 101 can transmit data corresponding to subframe 2 to the base station 102 through the frequency domain position N3 in step 403. For sub-frame 3, it may be directly determined that the frequency domain position of sub-frame 3 is equal to the frequency domain position of sub-frame 2, i.e., equal to frequency domain position N3. For subframe 4, since subframe 4 is the first subframe of TTI Group #2, the frequency domain position N4 corresponding to subframe 4 can be obtained through formula (4), i.e. in step 403, the user equipment 101 may transmit data corresponding to subframe 4 at frequency domain position N4. For subframe 7, the frequency domain position of subframe 4, that is, frequency domain position N4, may be directly determined, so that the user equipment may transmit data corresponding to subframe 7 at frequency domain position N4. If the transmission of TTI Bundle #1-1 fails, the user equipment 101 may utilize TTI Bundle #1-2 to perform a second transmission, at this time, TTI Group #1 of TTI Bundle #1-2 may send data at frequency domain position N5, and TTI Group #2 of TTI Bundle #1-2 may send data at frequency domain position N6, where the frequency hopping result of this example is shown in fig. 6 and will not be described herein. Wherein, N3 and N5 may be the same or different, and N4 and N6 may be the same or different.

Through the above description of the scheme of the embodiment of the present invention, it can be seen that frequency domain positions corresponding to the remaining subframes in the TTI Bundle are kept consistent with frequency domain positions corresponding to the first subframe in the TTI Bundle or the first subframe of the TTI Group in the TTI Bundle after frequency hopping, and frequency hopping between TTI bundles, or both within and between TTI bundles in the TDD network is achieved, so that a better frequency gain can be obtained. The frequency hopping scheme is compatible with the existing frequency hopping scheme of non-TTI Bundle frequency hopping, so that the implementation complexity of the frequency hopping of the TTI Bundle of the TDD system is reduced.
