Description

Method and device for determining base sequence and cyclic shift hopping

The present invention relates to the field of communications, and in particular, to a method for determining a sequence of uplink channels and signal transmissions, a cyclic shift hopping, and an apparatus therefor. Background technique

In the Long Term Evolution Advanced (LTE-A) system, Coordinated Multi-point (CoMP) transmission/reception is included as one of the key technologies in the LTE-A system. The cooperative transmission scenario uses the geographically adjacent transmission points to cooperatively transmit signals to the user equipment. For the small-area users, the signal quality can be improved and the coverage can be expanded.

Currently, the following four scenarios are included for the uplink and downlink CoMP (UL/DL CoMP) system.

Scenario 1: Homogenous Network with Intra-site CoMP (Scenario 2): Scenario 2: A homogeneous network with high transmit power remote radio unit (RRH); Scenario 3: Macro cell range A heterogeneous network scenario with different cell identities (Cell IDs) that distribute low-power RRHs;

Scenario 4: The macro cell range distributes heterogeneous network scenarios with the same cell ID for low-power RRHs.

The uplink channel may include a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Share Channel (PUSCH). The uplink signal transmission may include a modulation reference signal (DMRS, Demodulation Reference Signal) transmission. The following is an example of PUSCH DMRS.

Currently, in the uplink DMRS scheme in Rel. 10, the PUSCH DMRS base sequence is divided into 30 sequence groups, and the sequence group label is represented by M, t/e {0, 1, 2, ..., 29} Each sequence group contains one or two base sequences, and V represents the label of the base sequence in a sequence group, ν = 0,1. The PUSCH DMRS base sequence of a user is determined by the sequence group label M and the base sequence label V in a sequence group. All users in the same cell adopt the same sequence group, and users in different cells adopt different sequence groups. Since different users of a cell use the same sequence group label, when two users occupy the same or partially overlapping uplink resources to send DMRS, they can pass different cyclic shifts (CS, Cyclic Shift) and/or different positive The Orthogonal Cover Code (0CC) ensures the orthogonality of the DMRS in the cell, thereby ensuring low inter-cell interference. In addition, cell-specific (Cel-specific) cyclic shift hopping (CSH, Cycl ic Shift Hopping) and cell-specific (Cel l-specific) sequence group hopping (SGH, Sequence Group Hopping), uplink DMRS The CS value and the sequence group label jump with different time slots (Slots), thereby achieving further inter-cell interference randomization effects.

However, in the process of implementing the present invention, the inventors have found that in the uplink CoMP scenario of Rel. 11, this scheme of the uplink DMRS does not work well. The following examples illustrate:

Figure 1 is a schematic diagram of a CoMP scenario 3/4. As shown in FIG. 1 , in the CoMP scenario 3, the downlink physical control channel (PDCCH) of the CoMP UE1 is scheduled by the macro base station (Macro eNB), but the uplink signal is received by the macro base station and the RRH1. If the scheme of Rel. 10 is adopted, when the uplink resource transmission signal of the same or partially overlapping UE2 is occupied by the UE2 in the RRH1, the CoMP UE1 and the UE2 use different DMRS sequence groups, and the uplink signal of the UE2 interferes with the CoMP UE1. Thereby affecting the performance of the RRH1 receiving the CoMP UE1 signal.

In the case of CoMP scenario 4, the RRH and the macro base station share a cell identity. If the scheme in Rel. 10 is adopted, the uplink DMRS transmission of all users adopts the same sequence group, and on the one hand, the cell splitting gain cannot be achieved (Cel l Spl). On the other hand, due to the introduction of RRH, the number of users serving at the same time increases. Therefore, this scheme cannot provide sufficient orthogonal resources, such as CS and 0CC, and there will be a large amount of interference between RRHs, that is, inter-point. interference.

For PUCCH, the above problem also exists, and will not be described here. Summary of the invention

Various embodiments of the present invention will be described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not limiting of the invention. In order to enable a person skilled in the art to easily understand the principles and embodiments of the present invention, an embodiment of the present invention determines an uplink channel of a CoMP transmission system and a base sequence of a signal transmission thereof, and a method of cyclic shift hopping as an example. Note, but it can be understood that the present invention is not limited to the above system, and is applicable to other systems involving a base sequence for determining an uplink channel and its signal transmission, and cyclic shift hopping.

Currently, in Rel. 11, it has been determined that PUSCH DMRS is configured for user-specific (UE-specif ic) Base sequence and user-specific (UE-specific) cyclic shift hopping (CSH, Cycl ic Shift Hopping) ₀ User-specific base sequence can enable different cells in the CoMP scenario 1/2/3 The inter-user equipment UEs use the same base sequence to achieve orthogonality in different CS modes or 0CC modes. On the other hand, users in different RRHs in CoMP scenario 4 can adopt RRH-specific base sequences to achieve interference between RRHs. Randomization; User-specific CSH enables users between different cells under CoMP scenario 1/2/3 to achieve orthogonality in different 0CC manners based on different base sequences but the same CSH. At present, the corresponding solutions for how to implement the user-specific base sequence and user-specific cyclic shift jump are proposed, which are mainly classified into the following two types:

method one:

Independently configure user-specific base sequence and user-specific cyclic shift hopping, and control w ^BSI n ^{BSI CSH} through radio resources

(RRC, Radio Resource Control) protocol configures multiple sets of user-specific parameters V ^v ^ss ^Mt / 1, where, and jointly determine the user-specific base sequence, ^ replaces the cell that generates the base sequence in _Re l.

/•PUSCH /-PUSCH ₌ ( /-PUCCH ^^ ^Α CSH

, ie ^ ^ ; ^Ci "i' determines the user-specific cyclic shift hopping. Select one of the groups for the generation of the uplink DMRS by dynamic signaling.

For the above method, the independently configured user-specific base sequence and the user-specific cyclic shift hopping can realize that the users of different cells reach the orthogonality of the uplink DMRS in the 0CC manner based on different base sequences but the same cyclic shift hopping, but the method The RRC signaling overhead increases linearly when multiple sets of parameters are configured in the upper layer.

Method Two:

The user-specific base sequence and the user-specific cyclic shift hopping are jointly configured, and a virtual cell ID (virtual cel l ID ) is configured through RRC, and the virtual cell ID generates both a user-specific base sequence and a user-specific cyclic shift. Bit jump.

For the above method, since the user-specific base sequence and the user-specific cyclic shift hopping are commonly configured, it is impossible to implement orthogonality of the 0CC mode based on different base sequences between different users in the cell.

In order to solve the problem in the foregoing solution, an embodiment of the present invention provides a method for determining an uplink channel and a signal thereof. User-specific base sequence and user-specific cyclic shift hopping methods and apparatus for transmission.

On the network side, the method includes: configuring a related parameter, where the related parameter includes multiple user-specific virtual cell identifiers, or multiple sets of parameter information, and each set of parameter information includes users respectively used to determine a base sequence and a cyclic shift hopping a dedicated virtual cell identifier, or a plurality of sets of parameter information, and each set of parameter information includes a user-specific virtual cell identifier and a user-specific sequence group allocation label A _ss ; and selected from the configured related parameters for determining an uplink channel and a signal transmission The base sequence and the parameters of the cyclic shift hopping; the selected parameter is notified to the user equipment, and the user equipment determines the base sequence and the cyclic shift hop according to the parameter. The above problem can be solved by the embodiment of the present invention, which not only reduces signaling overhead, but also ensures system performance.

In this embodiment, when the related parameters are configured, the user-specific virtual cell identifier in the related parameter may be configured as follows: The same base sequence can be generated with the neighboring cell or the user equipment of the neighboring RRH, or the same cyclic shift Jump, or different base sequence and / or different cyclic shift jumps.

The configured user-specific virtual identifier may be an actual cell identifier or an identifier of an equivalent cell. For example, for the PUCCH transmission, the configured user-specific virtual cell identifier may include the cell identifier of the cell where the user equipment is located and the cell identifier of the neighboring cell; for PUSCH DMRS transmission, the configured multiple user-specific virtual cell identifier includes the The cell identifier of the cell where the user equipment is located, and the cell-specific parameter sequence group allocation label of the cell in which the user equipment is located can generate an equivalent cell identifier that is the same cyclic shift hopping as other user equipments in the neighboring cell.

In this embodiment, the parameters for determining the base sequence and cyclic shift hopping of the uplink channel and the signal transmission may be selected from the configured related parameters according to the actual scheduling situation of the user equipment and different purposes.

For example, when realizing inter-cell orthogonal PUCCH or PUSCH DM S transmission, selecting a user-specific virtual cell identifier that can generate the same base sequence as other user equipments of neighboring cells; or selecting other user equipments with neighboring cells can Generating two user-specific virtual cell identities of different base sequences and the same cyclic shift hopping; when transmitting PUCCH or PUSCH DM S for interference randomization, selecting other user equipments with neighboring RRHs can generate different base sequences And two or two user-specific virtual cell identities of different cyclic shift hops.

Specifically, when the configuration parameter is a plurality of user-specific virtual cell identifiers, for PUCCH transmission based on inter-cell orthogonal, selecting a virtual cell identifier that can generate the same base sequence as other user equipments of the neighboring cells, or selecting and phase Other user equipments of the neighboring cell can generate two user-specific virtual cell identifiers with different base sequences but the same cyclic shift hopping; for PUCCH transmissions to achieve interference randomization, selection and phase Other user equipments of the neighboring RRHs are capable of generating virtual cell identities of different base sequences and/or different cyclic shift hopping;

In addition, for the PUSCH DMRS transmission based on inter-cell orthogonality, when the virtual cell identifier is selected, the cell-specific sequence group allocation label is used for selection. That is, the two virtual cell identifiers are selected such that the cell-specific sequence group allocation label A _ss combined with the cell in which the user equipment is located can generate the same base sequence or different base sequence as other user equipments in the neighboring cell but the same cyclic shift hopping change. For the PUCCH transmission to achieve interference randomization, the two virtual cell identifiers are selected such that the cell-specific sequence group allocation label A _ss combined with the cell in which the user equipment is located can generate a base sequence different from other user equipments of the neighboring RRHs. / or different cyclic shift jumps.

For example, when the configured related parameters include multiple groups and each group includes user-specific virtual identifiers for determining a base sequence and a cyclic shift hop, respectively, for inter-cell based orthogonal transmission, the selection enables the user equipment and phase The other user equipments of the neighboring cell generate a set of parameters of the orthogonal PUCCH or PUSCH DM S sequence; for the transmission to interfere with the randomization, the selection may enable the user equipment to generate different base sequences and/or cyclic shifts with other user equipments of the adjacent RRHs. A set of parameters for a bit hopping PUCCH or PUSCH DMRS. Similar to the above, for the PUSCH DMRS transmission, when the virtual cell identifier is selected, the cell-specific sequence allocation label is used for selection. On the user side, the method includes: receiving parameter information for determining a base sequence and a cyclic shift hopping of the uplink channel and the signal transmission, where the parameter information may include a user-specific virtual cell identifier; or the parameter information may include two groups. The parameter and each set of parameters includes a user-specific virtual cell identifier and a user-specific sequence group allocation label A _ss; and the uplink channel and the signal transmission are determined according to the parameter information or according to the parameter information and the cell-specific parameter A _ss of the cell where the user equipment is located. Base sequence and cyclic shift jumps.

The following takes the PUCCH and the PUSCH as an example to describe a method for determining a user-specific base sequence and a user-specific cyclic shift hopping according to an embodiment of the present invention.

First, the case where the relevant parameters of the network side configuration are multiple cell identifiers will be described with reference to the accompanying drawings.

For PUCCH transmission and DMRS transmission carried on PUCCH:

Step 201: Configure related parameters.

In this embodiment, the related parameter includes a plurality of user-specific virtual cell identifiers N, and the configured multiple related parameters may be expressed as

}. Step 202: Select, from the configured related parameters, a parameter for determining a base channel (BS) and a cyclic shift hopping (CSH) of the uplink channel and the signal transmission;

In this case, two parameters can be selected from the configured related parameters, and the two parameters can be used to determine the base sequence BS and CSH respectively, and the selected two parameters, that is, the two cell identifiers N can be the same, or Different, it can be selected according to the actual scheduling situation and different purposes.

Step 203: Notify the user equipment UE of the selected parameter.

In this embodiment, the selected two cell identifiers may be respectively notified to the user equipment by using two independent signalings. When the user equipment UE obtains the parameter notified by the network side, the user-specific BS may be determined according to the parameter. And CSH.

3 is a flow chart of a method for determining a user-specific base sequence and cyclic shift hopping according to Embodiment 2 of the present invention. As shown in FIG. 3, on the user equipment side, the method includes:

Step 301: Receive, by the network side, parameters for determining a base sequence and a cyclic shift hopping of the uplink channel and the signal transmission;

In this embodiment, the network side may respectively indicate that the user equipment UE determines the parameters of the BS and the CSH by using two independent signalings, so that the user equipment UE respectively receives parameters for determining the BS and parameters for determining the CSH;

In this embodiment, the two user-specific virtual cell identifiers received by the UE may be the same or different. For example, different user-specific virtual cell identifiers, such as ^{V fll} , are used to determine the BS. And ¹ , ^im , used to determine CSH.

Step 302: Determine a base sequence and a cyclic shift hopping of the uplink channel and the signal transmission according to the parameter. In this embodiment, after obtaining the foregoing parameters, the BS and the CSH may be determined by using the foregoing parameters, where the BS and the CSH may be determined. It is determined by any means existing, and the following is explained by way of example. In this embodiment, if the parameter for determining the BS received in step 301 is ^Vffil and the received parameter for determining the CSH is as an example, the process of determining the BS and the CSH is as follows:

1, the determination of the base sequence

In this embodiment, the DMRS sequence carried on the PUCCH and the PUCCH is transmitted. For a user equipment, the PUCCH occupies only one resource block (Resource Block, RB), and the base sequence BS only follows the sequence group. The label "related" is independent of the base sequence label ^v .

In the time slot, the sequence group label M is determined by a combination of a group Hopping Pattern and a Sequence Shift Pattern, and its expression is

« = (/ _gh ) + / _ss ) mod30 (1) where /^ denotes a sequence group hopping pattern, indicating a time slot label, the range is [0~19], / _∞ denotes a sequence shift pattern.

The sequence group hopping pattern / _A can be obtained by using formula (2) _:

In equation (1), c ) = _C (8 + 0 is a pseudo-random sequence;

The initial value of _{cO Ci} „ As shown in equation (3), the initialization value of the pseudo-random sequence can be calculated at the beginning of each radio frame.

N rcell

ID

Init (3)

30 In equation (3), N is the cell identifier, and "L" means rounding down.

In addition, the sequence shift pattern of the PUCCH sequence can be obtained by using equation (4) / _∞

(4) It can be seen from equation (4) that the sequence shift pattern of the PUCCH sequence is determined by the cell identifier, that is, N. As can be seen from the above, the sequence group label " can be obtained by using equations (1) to (4), and it can be seen from the above formula that the sequence group label ί is related to the parameter.

It can be seen from the above that the base sequence of PUCCH and PUCCHDMRS can be obtained by using equations (1) to (4), and the base sequence is determined by the cell identity. Therefore, the user equipment can obtain the base sequence using equations (1) to (4) using the received parameter "" for determining the base sequence, such as N.

2. Cyclic shift hopping CSH determination Cyclic shift hopping pattern ^ Can be obtained by using equation (5):

(5)

In formula (5), _C (X) =

A, determined by the cell identifier N; / indicates the uplink symbol label of the current subframe, and for the regular cyclic prefix, the value ranges from / e (0, 6).

It can be seen from the above that CSH can be obtained by using equation (5), and the CSH is determined by the cell identifier. Therefore, the user equipment can use (5) to obtain CSH using the received parameters for determining CSH.

It can be seen from the foregoing Embodiments 1 and 2 that a plurality of user-specific virtual cell identifiers N for determining the base sequence and the CSH are configured on the network side, and parameters for determining the base sequence and the CSH are selected therefrom, and the user is notified by signaling. The device, after obtaining the parameter, the user equipment UE can obtain the base sequence and the CSH by using the parameter. In this way, both the signaling overhead and the performance of the system are not affected.

In this embodiment, the BS and CSH may be determined by an initialization seed of a CSI-RS sequence in a non-zero power channel state information reference signal resource configured in a predetermined downlink CoMP. In this way, the network side does not need to configure the virtual cell identifier dedicated to the user, and reuses the pre-configured initialization seed to reduce the network side signaling overhead.

Based on Embodiment 1, in order to further reduce the signaling overhead, the network side may not configure the multiple user-specific virtual cell identifiers, but use the non-zero power channel state information reference signal configured in the downlink CoMP (NZP CSI-S The initialization seed of the CSI-RS sequence in the resource. Thus, step 101 can be omitted. In step 102, one of the initialization seeds of the CSI-RS sequence in the non-zero power channel state information reference signal (NZP CSI-RS) resource configured in the predetermined downlink CoMP is directly selected. Or two initialization seeds are used as user-specific virtual cell identifiers; in step 103, the selected initialization seed is separately notified to the user equipment.

For DMRS transmission carried on the PUSCH during PUSCH transmission:

^(1)' (2)"'" (Λ }. Thus, the network side can reuse the initialization seed O of the CSI-RS sequence without separately configuring related parameters.

When determining the BS and the CSH, the network side may select two initial seeds for determining the BS and CSH from the pre-configured initial seed, such as Ο') for determining the BS, (for determining the SCH; and then passing the independent letter) The user equipment is notified to the user equipment; after receiving the parameters sent by the network side, that is, after the initial seed, the user equipment can determine the BS and CSH of the PUCCH format la/lb by using the parameter respectively. The specific calculation process is as described in Embodiment 2. Let me repeat.

Secondly, the PUSCH DMRS transmission in the above CoMP scenario is taken as an example for description.

Example 1: On the network side, the network side semi-statically configures the N sets of parameters { , ^Ν ^ ¹ Β } through high-level signaling (RRC parameters), and selects one of the group parameters, for example, the group parameters are selected. { ^^ , ^"; where, the determining BS is used to determine the _{CSH; the} network side notifies the user equipment by dynamic signaling, and specifically, can be dynamically indicated in the DCI. On the user equipment side, the user equipment receives the group After the parameter, the base sequence can be determined based on the cell-specific sequence group assignment label " ^Δ ". For details, see Embodiment 1; CSH is determined based on the cell-specific sequence group assignment label " ^Δ- ", as shown in Embodiment 2.

As shown in FIG. 18, the uplink receiving point of the CoMP UE is the eNB and the RRH1. When the CoMP UE and the legacy UE in the RRH1 occupy the same resource to send the PUSCH, the positive UE in the CoMP UE and the neighboring cell RRH1 is implemented. For the PUSCH DMRS, the network side can configure two sets of parameter information for the CoMP UE, namely, parameter group 1 { ^m , ^m } and parameter group 2 { ¹⁰ , . The parameter group 1 { ^Vm , ^Vm } indicates that the CoMP UE can generate the same PUSCH DMRS base sequence BS and the legacy UE in the coverage of the eNB based on the cell identifier of the eNB and the cell-specific sequence group allocation label ^{Δ of the} eNB.

On the user equipment side, the user equipment determines BS and CSH respectively based on the two parameters and the cell-specific sequence group allocation label. For the specific process, see Embodiment 2.

Example 3:

As shown in FIG. 18, N groups of NZP CSI-RS resources are pre-configured for the CoMP UE, and the initial seed "X" of the CSI-RS sequence of each group of resources is semi-statically notified to the CoMP UE, ie, CoMP, through high layer signaling (RRC parameters).

The PUCCH format la/lb (PUCCH format la/lb) for transmitting ACK/NACK in the above CoMP scenario is taken as an example to determine a user-specific base sequence and a user-specific cyclic shift hop (UE-specific base sequence and UE). -specific CS hopping ), to implement orthogonal transmission of inter-cell PUCCH format la/lb under CoMP scenario 1/2/3, and method for interference randomization transmission of PUCCH format la/lb between RRHs in CoMP scenario 4. Example 1: Implementation of CoMP scenario Orthogonal transmission of inter-cell PUCCH format la/lb under 1/2/3: FIG. 19 is a schematic diagram of PUCCH transmission in CoMP scenario 3 of an application example of the present invention. As shown in FIG. 19, the downlink control channel (PDCCH) of the CoMP UE is controlled by the eNB, and the eNBs RRH1 and RRH2 together constitute a downlink CoMP Management Set of the CoMP UE. The downlink CoMP management set of the CoMP UE is a set of points that the CoMP UE needs to perform CSI Channel State Information measurement.

In this example, the network side, such as an eNB, semi-statically configures three user-specific parameters through high-layer RRC signaling. ί ^ce11 r ^ce11 r ^ce11 I

The ρ _{υ of} the _{C() Mp} _(Η transmission is received by the _eNB and the R _RH 1 two points, at which time the legacy user UE1 in the coverage of the RRH1 transmits the PUCCH on the same time-frequency resource, The orthogonal transmission of the PUCCH of the CoMP UE and UE1 can be implemented in the following two ways:

Method 1: The CoMP UE and the PUCCH of UE1 use the same BS, and the orthogonality is achieved by different cyclic shift CS or 0CC, and the PUCCH of the CoMP UE and UE1 may adopt the same or different CSH. The specific implementation is as follows:

^ID eWs lD " any value in ^ID ₂ to determine CSH, for example to determine CSH

In this example, the PUCCH cyclic shift hopping CSH of the CoMP UE may be determined by the " _eNB " by using a _2- bit signaling parameter; and the PUCCH-based sequence BS of the CoMP UE is indicated by the _2- bit signaling parameter based on ί-cell - Cell A[ ^cel1 \ Al ^cel1

The \D stone angle in e RR /1 is set on the user equipment side, and the CoMP UE can receive the parameter for determining the BS and the parameter " ^m " for determining the CSH indicated by the network side; then determining the BS and the CSH based on the above parameters. For a specific calculation process, refer to Embodiment 2, and details are not described herein again.

It can be seen from the foregoing example that the PUCCH sequence sent by the CoMP UE is generated according to the cell ID of the RRH1, and the cyclic shift hopping is generated according to the cell ID of the cell eNB in which the cell is located. In this way, the PUCCH sequence sent by the CoMP UE has the same base sequence as the PUCCH sequence sent by the legacy user UE1 in the coverage of the RRH1, so as to achieve orthogonality by using the same base sequence with different cyclic shifts or different orthogonal masks. In addition, the cyclic shift hopping of the PUCCH sequence of the CoMP UE is generated according to the cell ID of the cell eNB in which the cell is located, indicating that the PUCCH sent by the CoMP UE and other users in the coverage of the eNB can be hopped in different base sequences but in the same cyclic shift. The orthogonality is achieved by different orthogonal masking methods.

Method 2. The CoMP UE and UE1's PUCCH adopt different base sequences, but the same cyclic shift hopping, and orthogonality is achieved by different orthogonal masks (0CC). The specific implementation is as follows: The difference from the method 1 is that for the CoMP UE, the network side selects {^ ^11βΛ3⁄4 ' ^Ν ^2 }

M ^cel1

The second parameter is used to determine CSH such that the CSH of the PUCCH sequence of the CoMP UE is the same as the CSH of the PUCCH sequence of UE1. At this time, even if the base sequences of the two user PUCCH sequences are different, the orthogonal transmission of the PUCCH on the same time-frequency resource can be realized by different orthogonal masks 0CC. In addition, since the CoMP UE and UE1 are orthogonal through different 0 CCs based on the same CSH, there is no requirement for the PUCCH base sequence of the CoMP UE and UE1. Therefore the CoMP UE can be based on

Any value in {^ ^' ^ ₂ } is determined, for example, "" is selected to determine the BS. The method for notifying the CoMP UE of the selected parameter and the method for determining the BS and the CSH by the CoMP UE is similar to the method 1 and is not described here.

It can be seen from the foregoing example 2 that the PUCCH sequence sent by the CoMP UE is generated by the BS according to the cell ID of the cell eNB in which the cell is located, and the CSH is generated according to the cell ID of the RRH1. In this way, the PUCCH sequence sent by the CoMP UE has the same CSH as the PUCCH sequence sent by the UE1, and different BSs can implement orthogonal transmission of the PUCCH of the CoMP UE and the UE1 on the same time-frequency resource with different orthogonal masks 0CC. . In addition, the base sequence of the PUCCH of the CoMP UE is generated according to the cell ID of the cell eNB in which the cell is located, indicating that the PUCCH sent by the CoMP UE and other users in the coverage of the eNB can be shifted by different cyclic cycles or different in the same base sequence. The orthogonal masking mode implements orthogonal transmission of PUCCHs of two users on the same time-frequency resource. Example 2 CoMP scenario Orthogonal transmission of inter-cell PUCCH format la/lb under 1/2/3: Figure 20 is a schematic diagram of PUCCH transmission in CoMP scenario 3 of an application example of the present invention. As shown in Figure 20,

The downlink control channel (PDCCH) of the CoMP UE is controlled by the eNB, and the eNB and the RRH1 together constitute a downlink CoMP management set of the CoMP UE. On the network side, four sets of user-specific parameters can be semi-statically configured through high-level RRC signaling.

Where each group represents a user-specific base sequence and user-specific cyclic shift

The N: N' bit hopping method also represents a method of generating a PUCCH sequence. Group 1 ^ ww w j indicates

The PUCCH base sequence BS and CSH are both generated based on the cell ID of the eNB; the group 2 { ^Ν ^^ ^Β ' ^ ^U ^ indicates that the PUCCH base sequence BS is generated based on the cell ID of the eNB, and the CSH is generated based on the cell ID of the RRH1;

A _eA3⁄4 } is opposite to group 2 and will not be described here; group ₄ {W ¹¹ AJ indicates that both the _pucCH -based sequence BS and CSH are generated based on the cell ID of RRH1.

The network side may indicate which combination is used to determine the BS and the CSH according to the specific scheduling condition of the CoMP UE uplink PUCCH. In this example, the PUCCH transmission of the CoMP UE is received by the eNB and the RRH1, and the legacy user UE1 in the coverage area of the RRH1 transmits the PUCCH on the same time-frequency resource. The following two ways are implemented to implement the CoMP UE and the UE1 in the phase. Orthogonal transmission of PUCCH on the same frequency resource:

method 1 :

The CoMP UE and the PUCCH of the UE1 adopt the same BS, and the orthogonality is achieved by different CSs or different 0 CCs, and the PUCCH of the CoMP UE and the UE1 may adopt the same or different CSHs. The specific implementation is as follows: Βρ ί^ ^ '

And select a set of parameters from the 4 groups, i.e., group ^{^{3 {^ U Ν ^ 1 ^}} }, wherein the BS is determined based on a cell ID ^{V lD} RRH1 determined on the basis of his _CSH cell eNB cell ID _"eNB".

Determining, by the 2-bit signaling parameter, the CoMP UE determines the group used by the BS and the CSH, that is, the group 3 is on the user side, and the CoMP UE receives the signaling sent by the network side, and can determine the BS and the CSH according to the parameters indicated by the network side. As described in Embodiment 2, details are not described herein again.

It can be seen from the above example that the PUCCH sequence sent by the CoMP UE is generated by the BS following the cell ID of the RRH1, and the CSH is generated according to the cell ID of the cell eNB in which the cell is located. In this way, the PUCCH sequence sent by the CoMP UE has the same base sequence as the PUCCH sequence sent by the UE1, so as to achieve orthogonality by different cyclic shifts or different orthogonal masking manners of the same base sequence. In addition, the CSH of the PUCCH sequence of the CoMP UE is generated according to the cell ID of the cell eNB in which the cell is located, indicating that the PUCCH sent by the CoMP UE and other users in the coverage of the eNB can be different in different base sequences but in the same cyclic shift. The orthogonal mask mode is orthogonal.

Method 2:

The CoMP UE uses different BSs from the PUCCH of UE1, but the same CSH is orthogonal to each other through different DE 0CCs. The specific implementation is as follows: ^ to determine

BS and CSH. That is, the BS of the PUCCH is generated based on the cell ID of the cell eNB in which it is located, PUCCH

]j ^ce11

The CSH is generated based on the cell ID of the RRH1. Others are similar to Method 1, and are not described here.

In this example, the PUCCH sequence sent by the CoMP UE is generated by the BS following the cell ID of the cell eNB in which it is located, and the CSH is generated according to the cell ID of the RRH1. In this way, the PUCCH sequence sent by the CoMP UE is The PUCCH sequence sent by UE1 has the same CSH, and different BSs can implement orthogonal transmission of the PUCCH of the CoMP UE and UE1 on the same time-frequency resource with different OCC. In addition, the BS of the PUCCH of the CoMP UE is generated according to the cell ID of the cell eNB in which the cell is located, indicating that the PUCCH sent by the CoMP UE and other users in the coverage of the eNB can be transmitted through different cyclic shifts or different positives in the same base sequence. The cross-masking mode implements orthogonal transmission of PUCCHs of two users on the same time-frequency resource. Example 3: Interference randomization transmission of PUCCH format la/lb between RRHs in CoMP scenario 4: FIG. 21 is a schematic diagram of PUCCH transmission in CoMP scenario 4 according to an application example of the present invention. As shown in FIG. 21, there are RRH1 and RRH2 in the eNB coverage, which share a cell ID _eNB , and legs i and 2 constitute a downlink CoMP measurement set of the CoMP UE, that is, three sets of CSI-RS resources allocated to the CoMP UE are used. For CSI measurement, the initialization seeds of the CSI-RS sequences of each group of CSI-RS resources are: and . Among them, ^l and ^z can be regarded as the virtual cell ID corresponding to RRH1 and RRH2. The RRH1 coverage area exists in Rel. 11 user UE1, and the RRH2 coverage area exists in Rel. 11 user UE2. CSH BS and the network side from a predetermined parameter selected for determining the initialization seeds, i.e., and ^ί N ceU X \ M ^eii

^ ^{m eNB} , ² >, where the cell ID " ^ allows the UE 1 to fal l back to the RIO mode of operation. The cell ID " allows the UE 2 to fal l back to the RIO mode of operation.

As shown in FIG. 21, the UE1 and the UE2 belong to the R11 users of different RRH coverages respectively. To obtain the cell splitting gain, the UE1 and the UE2 can occupy the same time-frequency resource to send the PUCCH, and at the same time, to randomize the interference of the two users between the RRHs. A different PUCCH base sequence BS and cyclic shift hopping CSH of UE1 and UE2 may be configured. In the present example, the network side indicates UE1 via a signaling bit based on ^{m eNB} ^{^,} Λ ^ PUCCH selected parameters to generate a sequence group, a 1-bit signaling indicates UE1 generates PUCCH cyclic shift hopping based on the selection parameters A . That is, the PUCCH sequence transmitted by UE1, whose base sequence and cyclic shift hopping are generated based on the virtual cell ID "I" of RRH1. For UE2, the network side indicates that UE2 generates a PUCCH base sequence based on the selection parameter in ^X ^ by 1-bit signaling, and the 1-bit signaling indicates that UE2 selects parameter ₂ based on ^v , ^1) to generate _PU CCH. The cyclic shift jumps. That is, the PUCCH sequence transmitted by the UE2, the base sequence and the cyclic shift hopping are both generated based on the virtual cell ID of the RRH2, and the method for determining the BS and the CSH is as described in Embodiment 2.

Based on the foregoing method, the UE1 and the UE2 can generate a PUCCH sequence based on mutually different virtual cell IDs, and use the same time-frequency resource to transmit the PUCCH, thereby achieving the effect of randomizing interference.

In addition, this example can be extended as follows:

When the UE1 and the UE2 occupy the same time-frequency resource to transmit the PUCCH, randomization interference is required. At the same time, in the RRH1 coverage area, the legacy UE also transmits the PUCCH on the same time-frequency resource. In this case, not only the interference randomization between the RRHs needs to be considered to obtain the cell splitting gain, but also the orthogonal transmission of the PUCCH between the UE1 and the legacy UE is considered. The interference randomization of the users in the coverage area of the RRH1 and the RRH2 is implemented in the following manner, and the orthogonal transmission of the PUCCH between the UE1 and the legacy UE is implemented: the network side indicates that the UE1 selects parameters based on ^v ^, ^A through 1-bit signaling. A generates a PUCCH base sequence, and 1-bit signaling indicates that UE1 generates a cyclic shift hopping of the PUCCH sequence based on the selection parameter "" in i^ ¹¹ '. That is, the base sequence and cyclic shift hopping of UE1's PUCCH are generated based on two different IDs respectively, and the base sequence is generated based on the virtual cell ID "I" of RRH1, and the cyclic shift hopping follows the traditional manner, that is, the cell ID of the eNB is generated. . In this way, the UE1 and the legacy UE are allowed to implement orthogonal transmission of the PUCCH on the same time-frequency resource by using different 0CCs in different PUCCH-based sequences but the same CSH. The network side instructs the UE ² to generate a PUCCH base sequence based on the selection parameters in the ^{Vm eNB} , ² i through 1-bit signaling. The PUCCH cyclic shift hopping of UE2 may be generated based on or based on "2".

On the user side, after the UE1 and the UE2 obtain the above parameters, the BS and the CSH may be determined based on the foregoing parameters, as in Embodiment 2. Example 4: Interference randomized transmission of PUCCH format la/lb between RRHs in CoMP scenario 4: FIG. 22 is a schematic diagram of PUCCH transmission in CoMP scenario 4 according to an application example of the present invention. As shown in Figure 22, there are RRH1 and RRH2 in the eNB coverage, which share a cell ID "". The _e NB, the RRH1, and the RRH2 form a downlink CoMP measurement set of the CoMP UE, that is, the network side allocates the CSI-RS resource to the CoMP UE. The CSI-RS sequence initialization seed of each group of CSI-RS resources is: , ^l and ^ where ι and ² can be regarded as virtual cell IDs corresponding to RRH1 and RRH2. The RRH1 coverage area exists in Rel. 11 user UE1, and the RRH2 coverage area exists in Rel. 11 user UE2.

The network side may semi-statically configure four sets of user-specific parameters for the UE1 through high-layer RRC signaling, where the four sets of parameters are respectively ^eNB , and

^ , where each group represents a method for implementing PUCCH user-specific base sequences and user-specific cyclic shift hopping, and also represents a method for generating PUCCH sequences. 4 may be statically configured network-specific parameters for the set of users UE2 by semi-layer RRC signaling ^{^{^ 1 '^, ί w ceU}} Af cel1 \ {N cel1 Y \ {Υ N cel1 \ ί γ γ \ 4 the set of parameters to the other points ^βΛ , I, and mouth t, . Each group represents a method for implementing a PUCCH user-specific base sequence and user-specific cyclic shift hopping, and also a method of generating a PUCCH sequence.

The network side can indicate which group to adopt through dynamic signaling according to the actual scheduling situation. In order to obtain the cell splitting gain, UE2 in the coverage of RRH1 and UE2 in the coverage of RRH2 can reuse the same time-frequency resource to transmit PUCCH, but randomization interference is required. At this time, the UE1 can be indicated by the 2-bit signaling based on the group 4 X, , X,

^"L" is generated based PUCCH cyclic shift hopping sequence, which is based UE2 RRH2 virtual cell ^ID "Χ ι" base sequence and generates PUCCH cyclic shift hopping. It can be seen that the PUCCH sent by the UE1 and the UE2 not only have different base sequences, but also the sequence group hopping SGH and the cyclic shift hopping CSH are different, thereby achieving the effect of randomizing interference.

The following takes the transmission PUSCH DMRS as an example to determine a user-specific base sequence and a user-specific cyclic shift hopping to implement orthogonal transmission of inter-cell PUSCH DMRS under CoMP scenario 1/2/3, and RRH of CoMP scenario 4 Interference randomized transmission of inter-PUSCH DMRS is described. Example 5: Orthogonal transmission of inter-cell PUSCH DMRS under CoMP scenario 1/2/3:

FIG. 23 is a schematic diagram of PUSCH DMRS transmission in CoMP scenario 3 according to an application example of the present invention. As shown in Figure 23, The downlink control channel (PDCCH) of the CoMP UE is controlled by the eNB, and the eNBs RRH1 and RRH2 together constitute a downlink CoMP management set of the CoMP UE. The downlink CoMP management set of the CoMP UE is a set of points that the CoMP UE needs to perform CSI measurement.

Three sets of user-specific CSI-RS resources are configured for the CoMP UE, where the CSI-RS sequence initialization seed <, ^{= 1} , ² , ³ of each group of CSI-RS resources is the ID of each cell, that is, three groups of CSI-RS. The CSI-RS sequence of the resource generates the initial value according to ^{ro eA3⁄4} , "° leg, ^ro ^ ² respectively. In this example, the initialization seed of the CSI-RS is reused <, ^z ' ^{= 1} , ² , ³ , so that the user equipment can The initialization seed and the BS and CSH of the PUSCH DMRS are determined in combination with user-specific parameters "" configured by higher layer signaling such as RRC. Since the pre-configured initialization seed can be reused in the above case, only the user-specific parameter " ^Δ " is configured on the network side. The signaling overhead can be reduced. On the network side, three user-specific sequence group assignment labels "" are configured by high-layer signaling, such as RRC parameters, to indicate 1 ^ ' ^ ' ^SS , where each parameter is respectively associated with ^{VlD i; A3⁄4} , ^ Leg ¹ , ^{VlD Uiii2} corresponds.

As shown in Figure 23, the PUSCH DMRS transmission of the CoMP UE is received by the eNB and the RRH1. At this time, the legacy user UE1 in the coverage of the RRH1 transmits the PUSCH DMRS on the same time-frequency resource. The following two methods implement CoMP. Orthogonal transmission of PUSCH DMRS on UE and UE1 on the same time-frequency resource:

method 1 :

The CoMP UE and the PUSCH DMRS of the UE1 adopt the same BS, and the orthogonality is achieved by different CSs or different 0 CCs, and the CoMP UE and the PUSCH DMRS of the UE1 may adopt the same or different cyclic shift hopping. The specific implementation manner is as follows: On the network side, three user-specific sequence group assignment labels " ^Δ " are assigned, which are expressed as ^^ '' ^ where each parameter is correspondingly corresponding; 3 = AT ^{611 is} selected to determine BS and CSH Parameters; among them,

1) For the BS: the network side selects, for the CoMP UE, the initialization seed of the second group of CSI-RS resources in the corresponding CSI-RS resource, ie, mw^ ¹ , and indicates the selected parameter by using 2-bit signaling parameters. γ _

2) For CSH: The network side selects which user-specific sequence group is assigned the label " ^Δ ^" for the CoMP UE and the initial seed "" of the corresponding CSI-RS resources in the corresponding CSI-RS resources. In this example, since the CoMP UE and UE1 are orthogonal based on the same BS, there is no requirement for CSH. Therefore, the network side can choose any and its corresponding " ^X ". For example, choose

The CSH of the PUSCH DMRS is generated based on the cell-specific parameter " ^Δ " of the eNB's cell ID " ^N ^ ^eNB " and eNB.

The selected parameter is notified to the parameters selected by the CoMP UE network side by independent signaling. For example, can pass

The signaling parameter indicates that the selected parameter i ^{ω βΛ3⁄4} ^{Δ is} on the user equipment side. After receiving the above parameters, the CoMP UE can determine the BS and CSH specific calculation process according to the parameter, as in Embodiment 2, and details are not described herein again.

It can be seen from the above example that the PUSCH DMRS base sequence of the CoMP UE is the same as the PUSCH DMRS base sequence of the legacy UE1 in the RRH1 coverage. At this time, the CoMP UE and the UE1 can implement orthogonal transmission of the PUSCH DMRS on the same time-frequency resource according to different CSs or different 0CCs.

Method 2: The CoMP UE and UE1's PUSCH DMRS adopt different base sequences, but the same cyclic shift hopping, and orthogonality is achieved by different orthogonal masks (0CC). The specific implementation is as follows:

2) For the BS: The network side selects which user-specific parameter " ^Δ- " for the CoMP UE and the initialization seed " ^X " of the first group of CSI-RS resources in the corresponding CSI-RS resource. In this embodiment, since the CoMP UE and the RRH1 UE1 are orthogonal according to the same CSH through different orthogonal masks 0CC, there is no requirement for the BS. Therefore, the network side can choose any "" and its corresponding " ^X ". For example, selecting, indicating that the BS of the PUSCH DMRS of the _{CoMp UE is} generated based on the cell-specific parameter " ^Δ " of the cell ID " ^N ^ ^eNB " and the eNB of the eNB.

On the user equipment side, after the CoMP UE receives the foregoing parameters, the specific calculation process of the BS and the CSH may be determined according to the parameter, as in Embodiment 2, and details are not described herein again.

In the above example, the PUSCH DMRS sequence sent by the CoMP UE is generated by the BS following the cell ID "" of the cell eNB in which it is located and the cell-specific sequence group allocation label " ^Δ " of the eNB.

A rcell _Λ RRH1 is generated by the cell ID "^ leg" of RRH1 and the cell-specific sequence group assignment label "" of RRH1. In this way, the PUSCH DMRS sequence sent by the CoMP UE has the same CSH as the PUSCH DMRS sequence sent by the UE1, and different BSs can implement the orthogonality of the PUSCH DMRS of the CoMP UE and the UE1 on the same time-frequency resource with different 0CCs. transmission. In addition, the BS of the PUSCH DMRS of the CoMP UE is generated according to the cell ID of the cell eNB in which it is located and the cell-specific sequence group allocation label " ^Δ " of the eNB, indicating that the CoMP UE and other users in the coverage of the eNB are sent. The PUSCH DMRS can implement orthogonal transmission of PUSCH DMRSs of two users on the same time-frequency resource by using different cyclic shifts or different orthogonal masking manners in the same base sequence. Example 6: Orthogonal transmission of inter-cell PUSCH DMRS under CoMP scenario 1/2/3: FIG. 24 is a schematic diagram of PUSCH DMRS transmission in CoMP scenario 3 according to an application example of the present invention. As shown in FIG. 24, the downlink control channel (PDCCH) of the CoMP UE is controlled by the eNB, and the eNB, RRH1 and RRH2 jointly form a downlink CoMP management set of the CoMP UE.

The downlink CoMP management set of the CoMP UE is a set of points that the CoMP UE needs to perform CSI measurement. As shown in FIG. 24, the PUSCH DMRS transmission of the CoMP UE is received by the eNB and the RRH1. In this example, the user-specific BS and the user-specific CHS that the CoMP UE transmits the PUSCH DMRS sequence are determined based on the network-side configured user-specific parameter "^ ^U " and the cell-specific sequence group assignment label " ^Δ ". The network side semi-statically configures three user-specific parameters "", ie, ^v _m ' ^ _ml ^ _ro ² , through high-layer RRC signaling. Wherein, the parameter " ^eNB " and the cell-specific sequence group allocation label " ^Δ " combination of the eNB can generate the BS and CSH of the same PUSCH DMRS as the legacy user within the coverage of the eNB. The cell-specific sequence group assignment label " ^Δ " combination of the parameters "TM" and p _e NB can generate the BS and CSH of the same PUSCH DMRS as the legacy user within the coverage of RRH1. Reference ¾ ^"N ^" cell-specific sequence group and allocating the reference numeral eNB ^"Δ" compositions capable of generating the same coverage RRH2 traditional users PUSCH DMRS BS and CSH.

In this embodiment, the legacy user UE1 in the RRH1 coverage area transmits the PUSCH DMRS on the same time-frequency resource as the CoMP UE, and the following two methods implement the orthogonal transmission of the PUSCH DMRS of the CoMP UE and the UE1: Method 1: The CoMP UE The same BS is used for the PUSCH DMRS of the UE1, and the orthogonality is achieved by different CSs or different 0CCs. The PUSCH DMRS of the CoMP UE and the UE1 may adopt the same or different CSH. The specific implementation is as follows: The network side configures three user-specific parameters ",,, ie ^^^' ^ ^!^ ;

1) For the base sequence BS: Select the second parameter " ^Vrol " among them to determine the BS of the PUSCH DMRS of the CoMP UE, and notify the CoMP UE by the 2-bit signaling parameter. On the user equipment side, after receiving the parameter, the CoMP UE may give the parameter "^ϊ" and the cell-specific parameter " ^Δ " to determine the user-specific BS. Therefore, the BS of the PUSCH DMRS of the CoMP UE is the same as the BS of the PUSCH DMRS of the UE1. At this time, the CoMP UE and the UE1 can implement orthogonal transmission of the PUSCH DMRS on the same time-frequency resource according to different CSs or different 0 CCs. 2) For CSH:

In this example, since the CoMP UE and UE1 are orthogonal based on the same BS, there is no requirement for CSH. Therefore, the CoMP UE can determine the CSH based on any value in {^^' and the cell-specific sequence group assignment label "" of the eNB. For example, in this embodiment, the network side selects the multiple parameters mentioned above.

M ^cel1

The first parameter in the number, " ^{ro eNB} ", informs the CoMP UE through 2-bit signaling parameters. In this way, in the CoMP

After receiving the "" indicated by the 2-bit signaling parameter on the network side, the UE may assign a label "Determining CSH" based on the parameter "" and the cell-specific sequence group.

It can be seen from the above example that the PUSCH DMRS sequence sent by the CoMP UE is the same as the BS of the PUSCH DMRS of the UE1, and the CSH of the PUSCH is the same as the CSH of the PUSCH DMRS of the traditional user of the cell _e NB. In this way, the PUSCH DMRS sequence sent by the CoMP UE has the same BS as the PUSCH DMRS sequence sent by the UE1, so as to achieve orthogonality by different cyclic shifts or different orthogonal masking manners of the same base sequence. In addition,

M ^cel1

The CSH of the PUSCH DMRS sequence of the CoMP UE is generated according to the cell ID " ^{ro eNB} " of the cell eNB in which it is located and the cell-specific sequence group allocation label "" of the eNB, indicating that the CoMP UE and the PUSCH transmitted by other users within the coverage of the eNB The DMRS can be orthogonalized by different orthogonal masking modes with different base sequences but the same cyclic shift hopping.

Method 2: The CoMP UE and UE1's PUSCH DMRS adopt different base sequences, but the same cyclic shift hopping, and orthogonality is achieved by different orthogonal masks (0CC). The specific implementation is as follows: The network side configures three user-specific parameters " ⁷ ^ ", BP^ ^ro ^' ^ro1 ' ^ro2 J _;

1) For cyclic shift hopping CSH: Select the second parameter "^ϊ" to determine the CSH of the PUSCH DMRS of the CoMP UE, and notify the CoMP UE by the 2-bit signaling parameter. On the user equipment side, after receiving the parameter, the CoMP UE can determine the user-specific CSH based on the parameter "" and the cell-specific sequence group allocation label " ^Δ ". Therefore, the CSH of the PUSCH DMRS of the CoMP UE is the same as the CSH of the PUSCH DMRS of the UE1. At this time, even if the base sequence BS of the CoMP UE and the UE1 are different, orthogonal transmission of the PUSCH DMRS on the same time-frequency resource can be implemented by using different orthogonal masks 0CC.

2) For the base sequence BS Since the CoMP UE and UE1 are orthogonal through different 0 CCs based on the same CSH, there is no requirement for the BS of the PUSCH DMRS of the CoMP UE and UE1. Therefore, the CoMP UE can determine the base sequence BS based on any value in {^^^' ^ ¹ '' ^Ν ^ and the cell-specific sequence group assignment label " ^Δ " of the eNB. For example, in this embodiment, the network side selects the first parameter " ^{Vro eNB} " of the plurality of parameters, and notifies the CoMP UE by using 2-bit signaling parameters. In this way, after the CoMP UE receives the "^^B" indicated by the 2-bit signaling parameter on the network side, the CoMP UE may assign a label based on the parameter "^^B" and the cell-specific sequence group.

" " Determine the BS.

It can be seen from the above example that the base sequence BS of the PUSCH DMRS sequence sent by the CoMP UE is the same as the base sequence BS of the PUSCH DMRS of the legacy user in the coverage area of the cell eNB, and the cyclic shift hopping CSH and the PUSCH DMRS of the UE1 are CSH is the same. In this way, the PUSCH DMRS sequence sent by the CoMP UE has the same CSH as the PUSCH DMRS sequence sent by the UE1, and different BSs can implement orthogonality of the PUSCH DMRS of the CoMP UE and the UE1 on the same time-frequency resource with different 0CCs. transmission. In addition, the base sequence BS of the PUSCH DMRS of the CoMP UE is determined according to the cell ID of the cell eNB in which it is located and the cell-specific sequence group allocation label " ^Δ " of the eNB, indicating that the CoMP UE and other users within the coverage of the eNB The transmitted PUSCH DMRS can implement orthogonal transmission of PUSCH DMRSs of two users on the same time-frequency resource by using different cyclic shifts or different orthogonal masking manners in the same base sequence. Example 7: Orthogonal transmission of inter-cell PUSCH DMRS in CoMP scenario 1/2/3:

Figure 25 is a schematic diagram of PUSCH transmission in a CoMP scenario 3 of an application example of the present invention. As shown in FIG. 25, the downlink control channel (PDCCH) of the CoMP UE is controlled by the eNB, and the eNB, RRH1 together constitute a downlink CoMP management set of the CoMP UE. The downlink CoMP management set of the CoMP UE is a set of points that the CoMP UE needs to perform CSI measurement. As shown in Figure 25, the PUSCH DMRS transmission of the CoMP UE is received by the eNB and the RRH1.

The following two ways are implemented to implement the positive PUSCH DMRS on the same time-frequency resource. Delivery:
