Description

Method and device for transmitting information

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for transferring information.

Background

A Machine Type Communication (MTC) User terminal (User Equipment or terminal), also called a Machine to Machine (M2M) User Communication device, is a main application form of the current internet of things.

In recent years, due to the high spectrum efficiency of Long-Term Evolution (Long-Term Evolution, abbreviated LTE)/Long-Term Evolution advanced (Long-Term Evolution Advance, abbreviated LTE-Advance or LTE-a), more and more mobile operators select LTE/LTE-a as the Evolution direction of the broadband wireless communication system. MTC multi-type data services based on LTE/LTE-A will also be more attractive.

MTC devices are generally low-cost devices, and have the characteristics of relatively small supported RF (Radio Frequency) bandwidth, single receiving antenna, and the like, and the transmission and reception bandwidth of the MTC devices is generally 1.4 MHz. There is a class of MTC devices, such as electricity meters, which may be placed in the tin of basement, coverage is very poor, and 3GPP (3rd Generation Partnership Project) stands in R12 and R13, providing a solution for MTC UEs with low cost and requiring coverage enhancement. The current solution for coverage enhancement is to boost coverage by a large number of repetitions for certain channels. One way to reduce the number of repetitions of the channel is to frequency hop the channel in the frequency domain to obtain a frequency diversity gain. The existing PUSCH (Physical Uplink Shared Channel) frequency hopping method is only for frequency hopping within a subframe and between retransmitted subframes, and is not directly used for frequency hopping of a repeated Channel.

Example one

The present embodiment gives an example of a frequency hopping pattern. In this embodiment, the UE transmits uplink information or receives/detects downlink information on a designated PRB according to a frequency hopping pattern, where the transmitted uplink information includes at least one of: a Physical Random Access channel prach (Physical Random Access channel), a Physical Uplink Control channel pucch (Physical Uplink Control channel), a Physical Uplink shared channel pusch (Physical Uplink shared channel), wherein the received Downlink information is a Physical Downlink shared channel pdsch (Physical Downlink shared channel), and the detected Downlink information is a Physical Downlink Control channel pdcch (Physical Downlink Control channel)/enhanced Physical Downlink Control channel epdcch (enhanced Physical Downlink Control channel).

The UE transmits uplink information or receives/detects downlink information on a designated PRB according to a frequency hopping pattern, wherein the frequency hopping pattern is determined by at least one of the following information:

set of available subframes

Set of usable subbands

Time domain frequency hopping granularity

TDD uplink and downlink configuration

The available subframe set refers to a set of available subframes that can be used for frequency hopping. The subframe may be preset, for example, all subframes, or downlink may be the remaining subframes excluding MBSFN subframes. Or it may be eNB configured, such as eNB presets/informs the UE of a period in which usable subframes are indicated by bitmap. For example, a period of 20ms indicates a distribution of available subframes within every 20ms subframe, starting from subframe zero, and indicated by 20 bits. The set of available subframes for each channel may be the same or different.

The set of usable subbands refers to a set of subbands that can be used for frequency hopping. The subband set may be preset, for example, the system bandwidth is divided into a plurality of subbands according to a preset manner, and the usable subbands are all the divided subbands. Or the available subband set may be signaled by the eNB, or may be signaled by SIB or RRC signaling. For example, each system bandwidth is divided into multiple subbands in a preset manner, then the eNB includes a bitmap in a transmitted SIB to indicate that an available subband set includes, for example, the system bandwidth includes 8 subbands with indexes of 0, 1,2, 3, 4, 5, 6, and 7, and then "01111011" is used to indicate that the available subband set includes 6 subbands with indexes of 1,2, 3, 4, 6, and 7.

Or the eNB informs an offset value delta, the set of available subbands includes PRBs # delta-N from the eNB_RB- Δ -1 is divided into a plurality of sub-bands or partial sub-bands according to a predetermined rule, where N_RBNumber of PRBs included for system bandwidth, e.g. 20M time N_RB100. For example, PRB # Δ to N_RBThe- Δ -1 is divided from two sides to the middle, as shown in fig. 1, Δ ═ 2, every 6 consecutive PRBs from two sides to the middle are divided into one subband, and when divided into the middle, several remaining PRBs less than 6 in the middle may constitute one subband, or may not belong to any subband. A specific example is the PRB # Δ N_RBThe direct division of-1 into two sub-bands, also called two zones, is carried out when N_RBAnd when odd, does not include the middle PRBs. Frequency hopping is performed in two areas, for example, uplink control information can be transmitted by mirroring frequency hopping in the two areas. When the usable subband set only includes the partial subbands, specific subbands included in the usable subband set may be preset, for example, only two subbands on two sides, or notified by the eNB, or may notify the number of subbands, for example, 4 subbands from two sides to the center if 4 subbands are notified, such as

subbands #

0, 1,2, and 3 in fig. 1. The practical application is not limited to the above division.

The eNB may inform all channels of one set of available subbands or may inform one or more channels of the set of available subbands separately. The notification may be performed in any of the above manners.

The time domain hopping granularity Y of the frequency hopping means that the subbands where the designated PRB, in which the UE transmits the uplink information or receives/detects the downlink information according to the hopping pattern, are the same in Y consecutive subframes. Y consecutive subframes may be consecutive physical subframes, that is, a physical subframe defined in the prior art, for example, Y ═ 5, transmitted in sub-band #0 in sub-frames 0 to 4, and transmitted in sub-band #1 in sub-frames #5 to 9, where a subframe actually used for transmission may be available subframes in available subframe set, that is, subframes #0 to 9, or partial subframes in subframes #0 to 9, for example, available subframes are 1, 3, 7, 8, and 9, then transmitted in sub-band #0 in sub-frames 1 and 3, and transmitted in sub-band #1 in sub-frames 7, 8, and 9. Alternatively, Y consecutive subframes may be available subframes in Y available subframe sets, for example, in one radio frame, Y is 4, the available subframes are 0, 2, 3, 4, 5, 6, 8, and 9, and are transmitted on

available subframe #

0, 2, 3, and 4 in subband #0, and are transmitted on

subframes #

0, 2, 3, and 4 in subband # 1.

The time domain hopping granularity may be a preset value or a value notified by the eNB. Such as preset or notification Y-4.

The time domain hopping granularity may also be preset to be the number of repetitions corresponding to the lowest repetition level of the uplink channel or the downlink channel with the smallest number of repetitions or half of the number of repetitions in the uplink channel or the downlink channel with the same hopping pattern, for example, assuming that the EPDCCH and the PDSCH use the same hopping pattern, the number of repetitions of the PDSCH is the smallest, and the number of repetitions corresponding to the lowest repetition level is 10, then Y is 10 or 5.

Alternatively, for a channel, the time-domain hopping granularity may be defined as the number of repetitions corresponding to the lowest repetition level of the channel or half of the number of repetitions.

Alternatively, for a channel, the time-domain hopping granularity may be defined as the number of repetitions corresponding to the repetition level of the channel or half of the number of repetitions. For example, the PDSCH has a repetition level of 2, and the corresponding repetition level has a repetition number of 36, so that Y is 36 or 18.

The time domain frequency hopping granularity Y is determined by a third repetition number and the number of subbands to be frequency hopped in one repetition transmission, where the third repetition number is the repetition number required by one repetition transmission, for example, assuming that a PUSCH repetition transmission occupies 10 subframes and requires a PUSCH transmission to be frequency hopped between two subbands, the time domain frequency hopping granularity Y is 10/2-5. For example, a PUSCH repeat transmission occupies 20 subframes at a time, and requires PUSCH frequency hopping transmission between 4 subbands, so that the time domain frequency hopping granularity Y is 20/4-5.

Further, in order to randomize the inter-cell interference, the time-domain hopping granularity may also be a function of a cell identifier, such as Y ═ a + f (cell-ID), where a is a preset number or a number notified by the eNB, the cell-ID is the cell identifier, and f (cell-ID) is a function of the cell identifier, for example, f (cell-ID) ═ cell-ID mod 4, where mod represents a remainder.

Further, in an actual hopping pattern, if an unavailable subframe is encountered and the number of subframes transmitted/received on the same subband before the unavailable subframe does not exceed the time domain hopping granularity, hopping may occur at the unavailable subframe. For example, the available subframes are

subframes #

0, 1, 3, 4, 5, 6, 7, 8, 9, the time-domain hopping granularity is 4, and the starting hopping subframe is #0, then subframe #0, 1 is transmitted on subband #0, subframe #2 is unavailable,

subframe #

4, 5, 6, 7 is transmitted on subband #1 according to a hopping pattern, and subframe #9, 9 is hopped to subband #2 for transmission.

Further, the frequency hopping pattern is also determined by the number of PRBs and/or cell identities contained in the available subbands. The number of PRBs included in a subband may be preset or configured by the eNB. For example, the number of PRBs included in a subband is 6.

Further, in the TDD system, the time domain hopping granularity is also determined by the TDD uplink and downlink configuration.

For an uplink channel, the time domain frequency hopping granularity should be less than or equal to the number of continuous uplink subframes in the TDD uplink and downlink configuration.

For a downlink channel, the time domain frequency hopping granularity should be less than or equal to the number of continuous downlink subframes in the TDD uplink and downlink configuration. For example, the uplink and downlink configuration in the existing Rel-8 LTE protocol is shown in table 1, where the first column is an index of the uplink and downlink configuration.

For example, for the uplink and downlink configuration #2 including the special subframe, the number of consecutive downlink subframes is at most 3, and the downlink time domain hopping granularity Y may be set to 3, or a number smaller than 3, such as 2. When Y is 3, the UE transmits on the same narrowband in

subframes #

4, 5, 6, hopping to another narrowband in subframe 9 and subframes 0 and 1 of the next radio frame. Or for the uplink and downlink configuration #4 including the special subframe, the number of consecutive downlink subframes is at most 8, and the time domain frequency hopping granularity Y may be set to 8, or may be a number smaller than 8, for example, 4, and in 8 consecutive subframes, a hop to another subband after the 4 th subframe.

Further, the hopping pattern should be such that hopping occurs at the transition between uplink and downlink, so that unnecessary hopping is avoided. For example, for the uplink and downlink configuration #2 including a special subframe, the number of consecutive downlink subframes is at most 3, the downlink time domain hopping granularity Y is 3, and assuming that the UE receives downlink signals on the same narrowband on the consecutive Y subframes and the hopping occurs in the last subframe of the Y subframes, the hopping should occur in subframe 6 or subframe 1, for example, occupying subframe 6 or subframe 1 or occupying the first symbols of subframe 6 or subframe 1; assuming that the UE receives downlink signals on the same narrowband on Y consecutive subframes and that the frequency hopping occurs in the first subframe of the Y subframes, the frequency hopping should occur in subframe 4 or subframe 9, such as occupying subframe 4 or subframe 9 or occupying the first few symbols of subframe 4 or subframe 9.

Or, in the TDD system, the time domain hopping granularity is an uplink/downlink switching period or an integer multiple of the uplink/downlink switching period, where the time domain hopping granularity refers to a physical subframe. For example, for an uplink and downlink configuration with a downlink-to-uplink switching period of 5ms, the time-domain hopping granularity is 5ms or an integer multiple of 5ms, for example, transmission is performed on one sub-band #0 in

sub-frames #

0, 1,2, 3, and 4, where the uplink and downlink sub-frames are both transmitted on sub-band #0, and transmission is performed on sub-band #1 in

sub-frames #

5, 6, 7, 8, and 9, where the uplink and downlink sub-frames are both transmitted on sub-band # 1. For the uplink and downlink configuration with the downlink-to-uplink conversion period of 10ms, the time-domain hopping granularity may be 10ms or an integer multiple of 10 ms.

Example two

Assume that the total number of candidate frequency hopping sub-bands is N_sbThe candidate frequency hopping sub-bands are numbered as 0, 1,2 … … and N in sequence from lowest to highest according to the index of the starting PRB_sb-1, the number of PRBs contained in a subband is N_RB ^sb. Obtaining the virtual PRB index from the lowest index to the highest index from zero number of all the PRBs in the candidate sub-bands to be 0-N_sb×N_RB ^sb-1. Suppose that the PRB of the UE sending the uplink signal/receiving the downlink signal/detecting the downlink signal before the last frequency hopping is n_RBThe sub-band where is n_sb. E.g. virtual PRB index n_RB＝12，13，N _RB ^sb6, then the sub-band n in which it is located_sb＝3。

The following gives the hopping pattern expressed in terms of subband indices. Sub-band where resource of UE for sending uplink information or receiving/detecting downlink information is located

Can be derived from the following formula, here

Wherein t is a sub-frame number,

indicating a rounding down. f. of_hop(i) Is a frequency hopping factor, f_hop(-1)＝0。f_m(i) Is a mirror factor indicating that the resource allocated to the UE is mirrored in the narrow band after hopping to another narrow band, and in practical application, f_m(i) It may also be set to 0, i.e. no mirroring is performed. Pseudo-random sequence c (n) is generated from a 31 long Gold sequence:

c(n)＝(x₁(n+N_C)+x₂(n+N_C))mod2

x₁(n+31)＝(x₁(n+3)+x₁(n))mod2

x₂(n+31)＝(x₂(n+3)+x₂(n+2)+x₂(n+1)+x₂(n))mod2

where N is_c1600, the first m-sequence takes x₁(0)＝1,x₁(n) ═ 0, n ═ 1,2, 30. Initialization is performed and the second m-sequence is initialized with the cell identity indication, e.g. for FDD,

further, c_initIt can also be initialized with the type of information, e.g. for downstream data

For SIB, then

For EPDCCH, then

Further, c_initTime domain hopping granularity may also be used for initialization, such as

Further, c_initThe identity of the UE may also be used for initialization. For example

Wherein M is a constant.

In practical application, c may be generated according to one or more of cell identifier, uplink information or information type of the downlink information, time domain hopping granularity, and UE identifier_init。

The frequency hopping pattern, represented by the virtual PRB index, is given below.

Resource for UE to send uplink information or receive/detect downlink information

Can be derived from the following formula, here

Also a virtual index.

f_m(i)＝c(i·10)

Where t is a subframe number, for example, a subframe number in the prior art, i.e., a physical subframe number, i.e., t ═ 10 × n_f+n_sfWherein n is_fIs the radio frame number, n_sfFor subframe number, or there may be a fixed offset to the existing subframe number, e.g. t ═ 10 × n_f+n_sf+ C, wherein C is an integer. Or t may also be the number of the valid subframes, for example, all valid subframes in one period are sequentially increased from 0 to be numbered, for example, one period is 100 subframes, wherein the number of the valid subframes is 60, and the number is sequentially 0 to 59. The definition of t mentioned later is as described above.

f_m(i) Is composed ofAnd a mirroring factor indicating that resources allocated to the UE are mirrored in the narrowband after hopping to another narrowband.

Further, the c (n) may also be a preset sequence independent of the cell identity.

In the frequency hopping formula described above and in the several embodiments that follow, n for PDSCH/PUSCH_RBOr n_sbThe resource allocation domain in the downlink authorization/uplink authorization can be obtained, for example, two candidate frequency hopping sub-bands are obtained, the actual PRB indexes are 5-10 and 20-25, and the virtual indexes obtained after renumbering are 0-11 in sequence. The actual PRB indices of the frequency domain resources allocated to the UE in the downlink grant are 24 and 25, corresponding to a virtual index n_RB10 and 11, the frequency domain position on each subframe, i.e. 10 and 11, can be obtained by applying the above formula. For the EPDCCH, the eNB may also configure resources through RRC signaling, and the same method may obtain the frequency domain location of the EPDCCH on each subframe.

Alternatively, the frequency domain resource allocated to the UE may correspond to a preset subframe, that is, the resource refers to a resource of the UE on a certain preset subframe, for example, a resource of subframe #0 on a radio frame # 0. That is, for the above-described hopping pattern, the frequency domain resource allocated to the UE corresponds to subframe #0 over radio frame # 0. On the UE side, the UE regards the frequency domain resource allocated to the UE as

The UE may first n_f＝0、n _sf0 and

substituting the frequency hopping formula to reversely deduce n_RB. Then for other subframes, the UE combines the radio frame, subframe number and n of the other subframes_RBSubstituting the frequency hopping formula to obtain the frequency hopping values on other sub-frames

Or, the frequency domain resource allocated to the UE corresponds to a preset subframe forPDSCH/PUSCH, the preset subframe may be a starting subframe in which the UE receives the PDSCH or transmits the PUSCH. Similar to the above, that is, for the above-mentioned frequency hopping pattern, the preset or eNB configured resource

The corresponding UE receives the PDSCH or transmits the starting subframe of the PUSCH. The UE may first start n corresponding to the starting subframe_f、n_sfAnd

The frequency hopping formula can also be represented by the frequency domain positions before and after frequency hopping, i.e. the frequency domain position after frequency hopping is a function of the frequency before frequency hopping.

Or

For several embodiments in which the above-described hopping formula and following hopping patterns are defined by frequency domain positions before and after hopping, the initial frequency domain position may be preset or eNB configured. For example, for EPDCCH, a subband of EPDCCH configured by an eNB may be preset to detect the subband of EPDCCH for a UE on a preset subframe, such as subframe #0 on radio frame # 0. Every Y consecutive subframes the UE detects EPDCCH on the same subband and hops to another subband for reception until the next Y subframes. For PDSCH/PUSCH, the initial frequency domain location may be PRB allocated for downlink grant or uplink grant. The sub-frame where frequency hopping occurs during frequency hopping mayDetermined by the initial subframe in which the PDSCH/PUSCH is transmitted, e.g., starting from the initial subframe, every Y consecutive subframes are on the same subband, and the next Y subframes are hopped to another subband. Or frequency hopping at a fixed location, e.g. in the above equation

PRB allocated by downlink authorization or uplink authorization is the frequency domain position on the initial subframe for transmitting PDSCH/PUSCH according to

And the frequency hopping formula calculates the frequency domain location of the subsequent transmission.

EXAMPLE III

This embodiment gives an example of frequency hopping.

The rule of frequency hopping is to mirror frequency hopping within the candidate hopping subband or PRB, with the number of hopping subbands being 2. Assuming time-domain hopping granularity of Y, i.e., mirroring frequency hopping between two subbands every Y granularities, the frequency hopping times may be multiple. Assume that the total number of candidate frequency hopping sub-bands is N_sbThe candidate frequency hopping sub-bands are numbered as 0, 1,2 … … and N in sequence from lowest to highest according to the index of the starting PRB_sb-1, the number of PRBs contained in a subband is N_RB ^sb. Obtaining the virtual PRB index from the lowest index to the highest index from zero number of all the PRBs in the candidate sub-bands to be 0-N_sb×N_RB ^sb-1. Suppose that the PRB of the UE sending the uplink signal/receiving the downlink signal/detecting the downlink signal before the last frequency hopping is n_RBThe sub-band where is n_sb. E.g. virtual PRB index n_RB＝12，13，N _RB ^sb6, then the sub-band n in which it is located_sb＝3。

The frequency hopping is mirrored once at the 1 st subframe of each radio frame.

The frequency hopping pattern, represented by the virtual PRB index, is given below. Resource for UE to send uplink information or receive/detect downlink information

Can be derived from the following formula, here

Is the virtual index of the PRB.

Or

Wherein t is a subframe number.

In fig. 3, the total number of candidate subbands is 6, the time domain granule Y is 10, and the subframe of the initial transmission is subframe #0 on radio frame # 0. The subband index assigned to a UE is n_sb＝4，N_RB ^sb＝6，n _RB4 × 6+3 is 27. Mirrored PRB index of N_sb×N_RB ^sb-n_RB-1-8. The frequency hopping is mirrored once at #1 subframe of each radio frame.

The frequency hopping formula can also be represented by the frequency domain positions before and after frequency hopping, i.e. the frequency domain position after frequency hopping is a function of the frequency before frequency hopping. The following were used:

Example four

This embodiment gives an example of frequency hopping.

The rule of frequency hopping is fixed offset hopping within the candidate hopping subband or PRB, the number of hopping subbands being at least 2. Assuming time-domain hopping granularity of Y, fixed offset hopping occurs every Y granularities. Assume that the total number of candidate frequency hopping sub-bands is N_sbThe candidate frequency hopping sub-bands are numbered as 0, 1,2 … … and N in sequence from lowest to highest according to the index of the starting PRB_sb-1, the number of PRBs contained in a subband is N_RB ^sb. Obtaining the virtual PRB index from the lowest index to the highest index from zero number of all the candidate sub-bands as 0 to EN_sb×N_RB ^sb-1. Suppose that the PRB of the UE sending the uplink signal/receiving the downlink signal/detecting the downlink signal before the last frequency hopping is n_RBThe sub-band where is n_sb. E.g. virtual PRB index n_RB＝12，13，N _RB ^sb6, then the sub-band n in which it is located_sb＝3。

The sub-band index where the resource allocated to the UE is located is n_sbFix offset N as 1_sbOffset 4, i.e., a fixed offset of 4 subbands per half radio frame. The cyclic offset is from subband 0 when the offset exceeds the subband maximum index. Hopping once every 5 subframes. The number of hopping subbands in this example can be found to be 3.

I.e. a span of 4 sub-bands. The PRB index after frequency hopping is n_RB10+ 24-34. Hopping once every 5 subframes.

The frequency hopping formula can also be represented by the frequency domain positions before and after frequency hopping, i.e. the frequency domain position after frequency hopping is a function of the frequency before frequency hopping. As follows.

The rule of frequency hopping is fixed offset hopping within the candidate hopping subband or PRB, the number of hopping subbands being 2. Assuming that the time-domain hopping granularity is Y, i.e. fixed offset hopping is performed every Y granularities, the frequency hopping may be performed many times.

EXAMPLE six

The rule of frequency hopping is to hop within a candidate hopping subband or PRB according to a certain rule, the number of hopping subbands being at least 2. Assuming that the time domain hopping granularity is Y, i.e. every Y granularities a certain regular frequency hopping is performed, the frequency hopping times may be multiple. Assume that the total number of candidate frequency hopping sub-bands is N_sbThe candidate frequency hopping sub-bands are numbered as 0, 1,2 … … and N in sequence from lowest to highest according to the index of the starting PRB_sb-1, the number of PRBs contained in a subband is N_RB ^sb. Obtaining the virtual PRB index from the lowest index to the highest index from zero number of all the PRBs in the candidate sub-bands to be 0-N_sb×N_RB ^sb-1.

The following gives the hopping pattern expressed in terms of subband indices. The sub-band where the resource for transmitting uplink information or receiving/detecting downlink information by the UE is located

Can be derived from the following formula, here

Is a subband index. The frequency hopping formula is represented by the frequency domain positions before and after frequency hopping, i.e., the frequency domain position after frequency hopping is a function of the frequency before frequency hopping. As follows.

The null value is ignored when reading.

Here, the

The hopping pattern represented by the virtual PRB index is:

example eight

The present embodiment provides a solution to frequency hopping in case of collision.

In a sending subframe of the PRACH, when a designated PRB corresponding to a hopping pattern for sending uplink data overlaps or partially overlaps with the PRACH resource, the uplink data is hopped to another available subband, for example, to an adjacent available subband, or is not sent, that is, the sending is abandoned in a subframe where the PRACH is located. As shown in fig. 8.

And the repetition level of the PUSCH is not lower than the repetition level of the PRACH. Here, the higher the repetition level, the greater the corresponding number of repetitions. For example, the repetition level of the PUSCH is 1, the corresponding repetition number is 50, the repetition level of the PRACH is 0, and the corresponding repetition number is 10, so that when the PUSCH hops to a subband configured for the PRACH in a certain subframe according to a hopping pattern, transmission should be skipped or abandoned. This process can avoid the PUSCH being affected by PRACH signals with better channel conditions.

Or the repetition level of the PUSCH is not lower than the repetition level of the PRACH. This process may protect the normal transmission of PRACH.

And when the designated PRB corresponding to the frequency hopping pattern for sending the downlink data and the PRB or the sub-band of the SIB, PBCH or Paging are completely or partially overlapped, skipping to other available sub-bands to send the downlink data or not sending the downlink data on the sub-frames, namely, abandoning sending in the SIB and/or the physical broadcast channel and/or the sub-frames of the Paging message and/or the scheduling Paging message. For example, in subframe #0, SIB1/paging is blindly transmitted on subband #4, and according to the hopping pattern, if the PDSCH in subframe #0 is transmitted on subband #4, the UE should not transmit in this subframe.

Example nine

The frequency domain hopping rule of the frequency hopping pattern of the uplink data and the frequency hopping pattern of the uplink control information is the same, or the frequency domain hopping rule of the frequency hopping pattern of the uplink data and the frequency hopping pattern of the PRACH is the same, or the frequency domain hopping rule of the frequency hopping pattern of the uplink control information and the frequency domain hopping pattern of the PRACH is the same, or the frequency domain hopping rule of the frequency hopping pattern of the downlink control information and the frequency hopping pattern of the downlink data is the same.

Further, the frequency hopping pattern of the downlink control information is identical to a frequency domain hopping rule of the frequency hopping pattern of the downlink data except for the SIB 1.

The same frequency domain hopping rule means that the relationship between the subband positions before and after the frequency hopping or the PRB position is the same, for example, in the foregoing embodiments 2 to 7, the UE transmits the uplink signal/receives the downlink signal/detects the subband position of the downlink signal this time

Relative to the position of the subband prior to the last hop

The formula of (c) is the same.

Example ten

The sub-frame where the frequency hopping occurs is determined by a cell identity. Such as the frequency hopping formula for the above embodiments

May be related to cell identity, e.g. by changing the expression of i to

Where cell-ID is a cell identity and f (cell-ID) is a function of the cell identity, such as f (cell-ID) ═ cell-ID mod 10. This randomizes the frequency hopping between different cells and avoids interference from always occurring.

EXAMPLE eleven

If the number of repetitions N_repIs preset or semi-statically configured, and the frequency hopping of the UE is enabled by DCI dynamic configuration, the number of repetitions when the UE actually transmits should be determined according to whether the frequency hopping is enabled.

Number of repetitions N if preset or semi-static configuration_repCorresponding to the repetition times when no frequency hopping is carried out, the frequency hopping is not enabled during actual transmission, and the repetition times of the actual transmission is N_rep(ii) a If frequency hopping is enabled for actual transmission, then frequency hopping is performedWill bring gain, the number of actual transmission repetitions should be larger than N_repSmall, e.g. α N_repWhere α is a hopping adjustment factor and is a value smaller than 1, for example, α is 0.8. Or the actual number of repetitions is N_rep- α ', where α' is another method of defining the hopping adjustment factor. The frequency hopping factor may be preset or eNB configured. The definition of the frequency hopping adjustment factor and the relationship between the number of repetitions of actual repeated transmission and the adjustment factor in practical applications are not limited to the above, as long as the obtained ratio of the number of repetitions of actual transmission to N is obtained_repIs small in size.

Number of repetitions N if preset or semi-static configuration_repThe corresponding repetition times during frequency hopping are not enabled during actual transmission, and the repetition times during actual transmission are more than N_repLarge, e.g. as beta N_repWhere β is a frequency hopping adjustment factor, and is a preset value greater than 1, for example, α ═ 1.2; if frequency hopping is enabled during actual transmission, the number of repetitions of actual transmission is N_rep. Or the actual number of repetitions is N_rep+ β ', where β' is another method of defining the hopping adjustment factor. The definition of the frequency hopping adjustment factor and the relationship between the number of repetitions of actual repeated transmission and the adjustment factor in practical applications are not limited to the above, as long as the obtained ratio of the number of repetitions of actual transmission to N is obtained_repThe size is large. Practical application is not limited to N_repIs preset or semi-statically configured and the enabling of the frequency hopping of the UE is the case of DCI dynamic configuration, but can also be used in the case of other configurations. May be used for each uplink and downlink channel.

Further, the aforementioned frequency hopping adjustment factor may be set by N_repDetermining, different N_repCorresponding to different hopping adjustment factors.

Further, for the downlink control information, the aggregation level thereof may also be determined by C in a preset manner, where C is a preset aggregation level or an aggregation level configured by the eNB, for example, when frequency hopping is not enabled, the aggregation level is still C, and after frequency hopping is enabled, the actual aggregation level is reduced to half, or reduced by one level, for example, reduced to 4 from aggregation level 8.

Example twelve

In the TDD system, during the time when the UE transmits PUSCH/PUCCH according to the frequency hopping pattern, the UE may not receive EPDCCH, or the UE temporarily jumps to the same narrowband as PUSCH/PUCCH to receive EPDCCH. For example, for the uplink and downlink subframe configuration #1, subframes 0 to 9 are DSUUDDSUUD respectively, assuming that the UE transmits PUSCH/PUCCH in narrowband #0 at subframes 2 and 3, the UE also detects EPDCCH in narrowband #0 at

subframes

4, 5, and 6, and assuming that the UE transmits PUSCH/PUCCH in narrowband #1 at subframes 7 and 8, the UE also detects EPDCCH in narrowband #1 at subframe 9 and subframes 0 and 1 of the next radio frame. Alternatively, assuming that the UE transmits PUSCH/PUCCH in narrowband #0 at subframes 2 and 3, the UE detects EPDCCH in narrowband #0 also at subframe 1 and 2 and subframe 9 of the last radio frame, and assuming that the UE transmits PUSCH/PUCCH in narrowband #1 at subframes 7 and 8, the UE detects EPDCCH in narrowband #1 also at

subframes

4, 5, and 6.

Similarly, during the transmission of PRACH, the UE may not receive EPDCCH or the UE temporarily jumps to the same narrowband as the PRACH to receive EPDCCH.

EXAMPLE thirteen

When there are both UEs with enhanced coverage and UEs with enhanced non-coverage in a cell, the downlink information or uplink information of the UEs with enhanced non-coverage may use the same frequency hopping pattern as that of the UEs with enhanced coverage in the above several embodiments. Here, a non-coverage enhanced UE is a UE that does not use repeated transmission, i.e. only occupies one subframe at a time for transmission. For example, the downlink control information of the UE under non-coverage enhancement may be transmitted using the same frequency hopping pattern as the downlink control information of the UE under coverage enhancement in the cell.

Example fourteen:

the hopping pattern comprises a special hopping pattern, i.e. there is no hopping, i.e. either the uplink information or the downlink information is transmitted on the same narrowband during a transmission. The remaining hopping patterns can all be referred to as hopping patterns where there is frequency hopping. For example, for PUSCH, the eNB schedules PUSCH transmission on narrowband #1 with a repetition number R of 20 subframes, and then within the 20 subframes of the PUSCH transmission, the PUSCH is always transmitted on narrowband # 1. The time domain hopping granularity may be considered meaningless at this point, or may be considered infinite.

Example fifteen:

during one transmission of the uplink information or the downlink information, the redundancy version RV of the information and/or the scrambling code sequence changes once every Z subframes (the change period of the redundancy version RV of the downlink information or the uplink information and/or the scrambling code sequence is Z subframes). The determination of Z is given in this example. When the downlink information is control information, scrambling code sequence is used for scrambling and carrying downlink control information of one or more users; when the downlink information and the up-down information are service information, the scrambling code sequence is used for scrambling a code word block of a single user.

Z is determined by the number of repetitions. Which may be equal to R, R/4, or floor (R/4), or ceil (R/4), where R is the number of repetitions of the information, floor () represents rounded down and ceil () represents rounded up. Or Z ═ R/(4k), floor (R/(4k)), or ceil (R/(4k)), where k is a positive integer. This applies to both scenarios where there is no frequency hopping for the hopping pattern and scenarios where there is frequency hopping for the hopping pattern.

Alternatively, Z is a fixed number, and Z ∈ {1, 2, 4}, which applies to both scenarios where the hopping pattern does not exist and scenarios where the hopping pattern does exist.

Alternatively, Z ═ 5k, or Z ═ 10k, where k is a positive integer greater than 0. This applies to both scenarios where there is no frequency hopping for the hopping pattern and scenarios where there is frequency hopping for the hopping pattern.

Alternatively, Z may also be determined by the time-domain hopping granularity Y, such as Z min (4, Y), or Z Y/4, or Y/4 rounded down, or Y/4 rounded up, or Y/2 rounded down, or Y/2 rounded up, or maximum of Y/4 and 2, maximum of Y/4 rounded down and 2, maximum of Y/4 rounded up and 2, or maximum of Y/2 and 2, maximum of Y/2 rounded down and 2, maximum of Y/2 rounded up and 2, and maximum of Y/2 rounded up and 2. This applies to the scenario where the hopping pattern is present.

Alternatively, Z may be a combination of the above-mentioned methods, for example, the minimum value calculated for any two of the above-mentioned methods, for example, Z ═ min (R/4, min (4, Y)), or Z ═ min (R/4, 2), or Z ═ min (R/4, Y). The Y-dependent approach can only be used for scenarios where the hopping pattern is hopping, and the Y-independent approach can be used for all scenarios.

In addition, Z may also be determined by whether there is frequency hopping in the frequency hopping pattern, for example, when there is no frequency hopping in the frequency hopping pattern, Z is R/4; when there is frequency hopping in the hopping pattern, Z ═ min (4, Y).

The RV may change every Z subframes according to a preset rule, for example, according to the order of 0, 2, 3, and 1.

The Z subframes may be physical subframes or usable subframes.

Example sixteen:

the present embodiment provides a method of transmitting information.

The method proposed by the embodiment can be used in mtc (machine Type communication) technology and NB-IoT (narrow-Internet of Things) system, and the method is not limited to be used in these two scenarios.

In this embodiment, the UE or eNB needs to repeat the frequency hopping transmission for a long time. For example, the UE repeatedly transmits 2048 subframes to transmit one uplink data packet. For full-duplex UE, when the UE transmits uplink information, it cannot receive downlink, and if the uplink transmission time is too long, the UE may lose time-frequency synchronization, so that some transmission gaps should be set in one-time repeated transmission of the UE, and in these transmission gaps, the UE stops sending information, and receives downlink information to perform time-frequency synchronization. The method mentioned in this embodiment may be used for uplink and downlink, and is not limited to be used for half-duplex UEs, but also may be used for full-duplex UEs. The following description is made by way of an example.

Determining a transmission gap (transmission interval) and a transmission period, and sending uplink information on a designated physical resource transmission block (PRB) according to the transmission gap, the transmission period and a frequency hopping pattern, or receiving or detecting downlink information on the designated PRB according to the frequency hopping pattern.

Here, the transmission period may include the transmission gap, for example, the transmission period is 512ms, and the transmission gap may be the last 60ms of the transmission period, i.e., 452ms is sent by the UE, and then 60ms is stopped being sent, followed by 452ms being sent again, and then 60ms is stopped being sent until the sending is completed. Alternatively, the transmission period may not include the transmission gap, for example, the transmission period is 512ms, the transmission gap is 60ms, and the UE sends 512ms, stops sending 60ms, then sends 512ms again, and then stops sending 60ms until the sending is completed.

The transmission gap or transmission period is preset or eNB configured. For example, the transmission gap or the transmission period is notified by DCI or RRC signaling or SIB.

The transmission period or the subframe corresponding to the transmission gap is preset or determined by the starting subframe sent by the UE.

For a preset subframe, for example, starting from subframe #0 of radio frame #0, the transmission period is 512ms, and the transmission gap is 60ms, if the UE transmits the starting subframe of subframe #0 of radio frame #50, then 12 subframes are transmitted, the transmission is stopped for 60ms, followed by 512 subframes, and then the transmission is stopped for 60ms until the transmission is completed. Or, the starting subframe of the transmission. For example, if the UE transmits 512 subframes from the starting subframe of the UE transmission, the UE stops transmitting for 60ms, then transmits 512 subframes, and then stops transmitting for 60ms until the transmission is completed.

Optionally, starting from a starting subframe of transmission, stopping transmitting y subframes every x subframes until the transmission is completed, wherein a transmission period is x subframes, and a transmission interval is y subframes.

Optionally, starting from a starting subframe of transmission, stopping transmitting y subframes every x-y subframes until the transmission is completed, wherein the transmission period is x subframes, and the transmission interval is y subframes.

Alternatively, starting with the starting subframe of the transmission, stopping transmitting y subframes for every a subframes transmitted, until the transmission is complete, wherein,

or

Or

Or

The transmission period is x subframes, the transmission interval is y subframes, and N is the total number of transmitted subframes. For example, assuming that N is 512, x is 200, and y is 60, then

The value of the transmission gap or the number of subframes corresponding to the transmission period is one of the following values:

1) an integer power of 2;

2)2 or 4 or multiples of 8 or 16

3) Integral multiples of the maximum time domain frequency hopping granularity, for example, the time domain frequency hopping granularity is one of 2, 4, 8 and 16, and if the maximum time domain frequency hopping granularity is 16, the value of the transmission gap or the transmission period is integral multiples of 16;

4) an integer multiple of 60;

5) an integer multiple of 100.

The following gives a way to determine the narrow band of transmission on the first subframe after the gap is transmitted.

On the first subframe after the transmission gap, the narrowband corresponding to the designated PRB may be the same as the narrowband corresponding to the last subframe before the transmission gap. As shown in fig. 10, the time domain hopping granularity Ych is 16, the UE hops between two narrow bands, and the hopping sequence is: narrow band 1, narrow band 2, … …. There is a frequency offset between the two narrow bands. The narrow band on the first subframe after Gap is the same as the narrow band on the last subframe before. Here, the subframe may be a physical subframe or an available subframe, and this definition is also applied to other parts of this embodiment.

Or, on the first subframe after the gap is transmitted, the narrowband corresponding to the designated PRB is the next frequency-hopping narrowband corresponding to the last subframe before the gap is transmitted. As shown in fig. 11, the time domain hopping granularity Ych is 16, the UE hops between two narrow bands, and the hopping sequence is: narrow band 1, narrow band 2, … …. There is a frequency offset between the two narrow bands. There is a frequency offset between the two narrow bands. And transmitting the narrow band 1 corresponding to the last subframe before the gap, and then the narrow band corresponding to the first subframe after the gap is the narrow band 2.

Or, on the first subframe after the transmission gap, the narrowband corresponding to the designated PRB is a frequency hopping narrowband obtained according to the frequency hopping pattern, with the subframe in the transmission gap as the transmission time. As shown in fig. 12, the time domain hopping granularity Ych is 16, the UE hops between two narrow bands, and the hopping sequence is: narrow band 1, narrow band 2, … …. There is a frequency offset between the two narrow bands. There is a frequency offset between the two narrow bands. And taking the transmission gap as transmission time, and obtaining a frequency hopping narrow band according to a frequency hopping pattern as a narrow band 2.

The following gives a way to determine the first hop after the transmission of the gap.

The first frequency hopping after the transmission gap is the first frequency hopping obtained according to the frequency hopping pattern by using the sub-frame in the transmission gap as the transmission time, as shown in fig. 12.

Alternatively, the first hop after the transmission gap is to hop for Ych subframes sent after the transmission gap. For example, when Ych is 16, 16 subframes are transmitted after the gap for frequency hopping.

The above-mentioned determination method of the first frequency hopping after the gap transmission and the determination method of the transmission narrowband on the first subframe after the gap transmission may be arbitrarily combined.
