technical field

The embodiment of the present invention relates to the field of mobile communication, in particular, a method for configuring and sending PUCCH resources of a physical layer uplink control channel and a device thereof. the

Background technique

In a wireless communication system, in order to assist the communication between the base station and the user equipment, the user equipment needs to feed back uplink control information to the base station. Uplink control information includes: Acknowledgment/Negative-Acknowledgment (ACK/NACK), which is used for user equipment to indicate to the base station whether the data is received correctly; rank indicator (Rank Indicator, RI), channel quality indicator (Channel Quality Indicator , CQI) and Precoding Matrix Indicator (Precoding Matrix Indicator, PMI), used for user equipment to indicate the measured downlink channel quality conditions to the base station; scheduling request indicator (Scheduling Request Indicator, SRI), used for user equipment to request uplink data from the base station resources, and other control information related to the uplink data transmission format. the

In the 3GPP ( ^3rd Generation Partnership Project, 3rd Generation Partnership Project) E-UTRA (Evolved Universal Terrestrial Radio Access, Evolved Global Terrestrial Radio Access) system, the user equipment needs to transmit the above-mentioned ACK/NACK, RI/ In order to transmit three kinds of uplink control information, CQI/PMI and SRI, the base station allocates dedicated physical layer uplink control channel (Physical Uplink Control Channel, PUCCH) resources for the user equipment respectively. As shown in Figure 1, it is a schematic diagram of mapping from PUCCH resource blocks to physical resource blocks in a subframe in the prior art, and 4 PUCCH resource blocks are reserved in PUCCH, respectively m=0, 1, 2, 3, where A PUCCH resource block occupies the upper and lower sidebands of the system respectively in two time slots of a subframe. The PUCCH channels are multiplexed through code division within one PUCCH resource block, and multiplexed through frequency division among different PUCCH resource blocks.

In the further evolution of 3GPP E-UTRA (Further Advancements for E-UTRA) system, more than two component carriers (Component Carrier) are supported to aggregate together for larger bandwidth transmission, and each component carrier can be configured to be compatible E-UTRA user equipment. E-UTRA user equipment is referred to as LTE user equipment for short, and the user equipment of the further evolution system of E-UTRA is referred to as LTE-A user equipment for short. From the perspective of LTE-A user equipment, the system can configure unequal numbers of downlink component carriers and uplink component carriers. Usually, the number of downlink component carriers is greater than the number of uplink component carriers; The number of carriers is greater than the number of uplink component carriers. At this time, in order to be better compatible with the LTE user equipment, it is necessary to reserve PUCCH resources compatible with the LTE user equipment of multiple downlink component carriers in one uplink component carrier. the

In order to realize the reservation of PUCCH resources compatible with LTE user equipment of multiple downlink component carriers in one uplink component carrier, one implementation method is to set different dynamic ACK/NACK resource mappings in the downlink broadcast information of each component carrier , and the PUCCH resources between different downlink component carriers do not overlap with each other. the

However, the sharing of PUCCH resources of multiple downlink component carriers and the compression of dynamic ACK/NACK mapping resource overhead of multiple downlink component carriers cannot be realized, so that the reserved PUCCH resources cannot be effectively used. the

Detailed ways

The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments. the

In the 3GPP E-UTRA system, there are two types of PUCCH channel structures, the first is called PUCCH format 1/1a/1b channel, and the second is called PUCCH format 2/2a/2b channel. The function of the PUCCH format 1/1a/1b channel is that the user equipment feeds back SRI or ACK/NACK information to the base station; the function of the PUCCH format 2/2a/2b channel is that the user equipment feeds back RI/CQI/PMI information to the base station, or simultaneously sends Feedback RI/CQI/PMI and ACK/NACK information. PUCCH format 1/1a/1b channels are code-division multiplexed on one PUCCH resource block through the cyclic shift of constant-amplitude zero-autocorrelation sequences and orthogonal block spreading sequences, and PUCCH format 2/2a/2b channels are The cyclic shift code division multiplexing of the related sequence is on a PUCCH resource block, and the PUCCH format 1/1a/1b channel and the PUCCH format 2/2a/2b channel can also be divided by the cyclic shift code division of the constant amplitude zero autocorrelation sequence Multiplexed on one PUCCH resource block. A PUCCH resource block that simultaneously multiplexes a PUCCH format 1/1a/1b channel and a PUCCH format 2/2a/2b channel is called a PUCCH mixed resource block. the

And in the 3GPP E-UTRA system, the resources reserved for PUCCH are determined by the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ and the fourth parameter N _PUCCH ⁽¹⁾ , where the first parameter N _RB ^HO represents the starting offset of the physical layer uplink shared channel when performing frequency hopping in the frequency domain, and is also the maximum number of resource blocks that can be used for PUCCH channel transmission in a time slot, and the second parameter N _RB ⁽²⁾ represents the maximum number of resource blocks that are only used to transmit PUCCH format 2/2a/2b channels, and the third parameter N _CS ⁽¹⁾ represents the number of resources allocated to PUCCH format 1/1a/1b channels on the PUCCH mixed resource blocks The number of cyclic shifts of the banner zero autocorrelation sequence, the fourth parameter N _PUCCH ⁽¹⁾ indicates the starting offset of dynamic ACK/NACK resource mapping in all PUCCH format 1/1a/1b channels. The dynamic ACK/NACK resource refers to the ACK/NACK resource implicitly corresponding to the control channel element label of the physical layer downlink control channel. As shown in Figure 2, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ and the fourth parameter N _PUCCH ⁽¹⁾ in the PUCCH resource configuration method according to the embodiment of the present invention Schematic diagram of the relationship with PUCCH resource blocks. In the figure, m represents a PUCCH resource block number. The first N _RB ⁽²⁾ (marked as m=0 to $m=N_{\mathrm{RB}}^{\left(2\right)}-1$ ) PUCCH resource blocks can be used to transmit PUCCH format 2/2a/2b channels, labeled as $m=N_{\mathrm{RB}}^{\left(2\right)}$ The PUCCH resource block is a hybrid PUCCH resource block, in which there are N _CS ⁽¹⁾ cyclic shifts of zero autocorrelation sequences for the transmission of PUCCH format 1/1a/1b channels, and the remaining labeled PUCCH resource blocks can be used for transmission of PUCCH format 1/1a/1b channel. It can be seen that the starting point of the PUCCH format 2/2a/2b channel is the starting point of the PUCCH resource block, and no notification is required; the starting point of the PUCCH format 1/1a/1b channel is determined by the second parameter and the third parameter notification. The second parameter Which PUCCH resource block the starting point is located in is given, and the third parameter further gives the starting point in the PUCCH resource block.

The embodiment of the present invention uses the PUCCH resource configuration parameters of the 3GPP E-UTRA system to reserve PUCCH resources compatible with LTE user equipment for multiple downlink component carriers in one uplink component carrier, so as to realize PUCCH resource sharing and dynamic ACK/NACK mapping resources overhead compression method. the

Embodiment one

As shown in FIG. 3 , the PUCCH resource configuration method in Embodiment 1 of the present invention is to set the same PUCCH format channel starting point and different dynamic acknowledgment/negative response resource mapping start offsets for multiple downlink component carriers; The PUCCH resources of the multiple downlink component carriers correspond to the same uplink component carrier. The starting point of setting the same PUCCH format channel is specifically setting the same second parameter and third parameter, wherein the second parameter indicates the maximum number of resource blocks used to transmit the PUCCH format 2/2a/2b channel; The number of cyclic shifts of the banner zero autocorrelation sequence allocated to the PUCCH format 1/1a/1b channel on the resource block. The setting of different dynamic acknowledgment/negative response resource mapping start offsets is specifically setting different fourth parameters, wherein the fourth parameter indicates that dynamic acknowledgment/negative response resources are mapped in all PUCCH format 1/1a/1b channels starting bias. Wherein when the difference between the fourth parameter of the second component carrier and the fourth parameter of the first component carrier is not less than the maximum number of control channel elements occupied by the first component carrier, the dynamic confirmation of the first component carrier and the second component carrier is set Acknowledgment/Nack Acknowledgment mapping resources do not overlap each other; or when the difference between the fourth parameter of the second component carrier and the fourth parameter of the first component carrier is less than the maximum number of control channel units occupied by the first component carrier, set the first component carrier The dynamic acknowledgment/negative response mapping resources of the carrier and the second component carrier overlap each other; the second component carrier is the next component carrier of the first carrier. Among them, in the further evolution system of 3GPP E-UTRA, in order to be better compatible with LTE user equipment, it is still necessary to broadcast and notify the first parameter, the second parameter, the third parameter and the fourth parameter in the downlink component carrier compatible with LTE user equipment . These parameters are receivable by both the LTE user equipment and the LTE-A user equipment. the

From the perspective of the communication system, when the number of downlink component carriers in the system is greater than the number of uplink component carriers, all user equipment scheduled on multiple downlink component carriers must obtain PUCCH resources from the same uplink component carrier. The same second parameter N _RB ⁽²⁾ and third parameter N _CS ⁽¹⁾ are broadcast and notified among multiple downlink component carriers that obtain PUCCH resources in the uplink component carrier to set the same PUCCH format 1/1a/1b channel starting point, and notify different The fourth parameter N _PUCCH ⁽¹⁾ is used to set different dynamic ACK/NACK resource mapping start offsets.

As shown in FIG. 4 , it is one of the schematic diagrams of the uplink carrier and the downlink carrier in the PUCCH resource configuration method of the embodiment of the present invention. In the figure, the downlink carrier has four downlink component carriers, which are downlink component carrier 1 and downlink component carrier 2 respectively. , downlink component carrier 3 and downlink component carrier 4, the uplink component carrier has 3 uplink component carriers, namely uplink component carrier 1, uplink component carrier 2 and uplink component carrier 3, the arrow is the uplink component carrier where the PUCCH corresponding to the downlink component carrier is located Indicates that all users scheduled by downlink component carrier 3 and downlink component carrier 4 must obtain PUCCH resources in uplink component carrier 3, and notify the same second parameter N _RB ^{(2 )} and the third parameter N _CS ⁽¹⁾ and the different fourth parameter N _PUCCH ⁽¹⁾ can reserve PUCCH resources compatible with LTE user equipment for the downlink component carrier 3 and the downlink component carrier 4 in the uplink component carrier 3, The broadcast notification of the second parameter N _RB ⁽²⁾ and the third parameter N _CS ⁽¹⁾ and the different fourth parameter N _PUCCH ⁽¹⁾ can be received by both the LTE user equipment and the LTE-A user equipment.

In this case, each downlink component carrier only needs to notify the user equipment of a set of PUCCH resource configuration parameters through a broadcast message, that is, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , and the third parameter N _CS ^{( 1)} and the fourth parameter N _PUCCH ⁽¹⁾ .

In this way, the base station transmits the same PUCCH resource configuration second parameter N _RB ⁽²⁾ , third parameter N _CS ⁽¹⁾ , and different PUCCH resource configuration fourth parameter N _PUCCH ⁽¹⁾ in multiple downlink component carriers. PUCCH resources compatible with LTE user equipment are reserved for the multiple downlink component carriers in one uplink component carrier.

As shown in FIG. 5, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ and the fourth parameter N _PUCCH ^{(1 )} , where N _PUCCH,i ⁽¹⁾ represents the fourth parameter N _PUCCH ⁽¹⁾ of the i-th downlink component carrier. It can be seen from the figure that different fourth parameters N _{PUCCH, i} ⁽¹⁾ and N _{PUCCH, i+1} ⁽¹⁾ are respectively set for the i-th and i+1-th downlink component carriers.

Further, regardless of whether the number of downlink component carriers in the system is equal to the number of uplink component carriers, an LTE user equipment can only identify one downlink component carrier and one uplink component carrier, and an LTE-A user equipment can identify n1 downlink component carriers and n2 uplink component carriers, wherein n1 downlink carriers and n2 uplink component carriers are configured by the base station for LTE-A user equipment, n1≥1, n2≥1, and n1 and n2 may not be equal. A downlink component carrier and an uplink component carrier that can be identified by an LTE user equipment are called a paired component carrier, otherwise they are called an unpaired component carrier. the

As shown in FIG. 6 , it is the second schematic diagram of the uplink carrier and the downlink carrier in the PUCCH resource configuration method of the embodiment of the present invention. The downlink carrier in the system has four downlink component carriers, which are downlink component carrier 1 and downlink component carrier 2 respectively. , downlink component carrier 3 and downlink component carrier 4, the uplink component carrier in the system has 4 uplink component carriers, which are uplink component carrier 1, uplink component carrier 2, uplink component carrier 3 and uplink component carrier 4, forming 4 pairs Component carriers (downlink component carrier 1 and uplink component carrier 1, downlink component carrier 2 and uplink component carrier 2, downlink component carrier 3 and uplink component carrier 3, downlink component carrier 4 and uplink component carrier 4). The hollow arrow in the figure indicates the indication of the uplink component carrier where the PUCCH corresponding to the downlink component carrier of the LTE user equipment is located, and the solid arrow indicates the indication of the uplink component carrier where the PUCCH corresponding to the downlink component carrier of the LTE-A user equipment is located. The base station also configures three downlink component carriers for a certain LTE-A user equipment, that is, downlink component carrier 2, downlink component carrier 3 and downlink component carrier 4, and one uplink component carrier, that is, uplink component carrier 3. When the base station configures multiple downlink component carriers and multiple uplink component carriers for an LTE-A user equipment at the same time, the PUCCH resources of the multiple downlink component carriers of the user equipment can be distributed to multiple uplink component carriers for acquisition, or Collect and obtain from one uplink component carrier, which is called the uplink primary component carrier of the LTE-A user equipment. the

For LTE-A user equipment, the base station can configure multiple downlink component carriers to support higher data transmission rates, and the number of ACK/NACK bits fed back is more than that of LTE user equipment. The ACK/NACK feedback of the LTE-A user equipment may use the PUCCH format 1/1a/1b channel, or the PUCCH format 2/2a/2b channel. These two channel formats are already supported by the LTE user equipment, and the adoption of these two channel formats for the ACK/NACK feedback of the LTE-A user equipment can enable the LTE user equipment and the LTE-A user equipment to coexist better in the system. The timing relationship between the physical layer downlink control channel and the uplink ACK/NACK feedback of the LTE-A user equipment and the LTE user equipment may be the same or different. the

The LTE-A user equipment carrier is defined as follows: When the LTE user equipment and the LTE-A user equipment have different timing relationships from the physical layer downlink control channel to the uplink ACK/NACK feedback, and the ACK/NACK feedback of the LTE-A user equipment uses PUCCH For channel format 1/1a/1b, it refers to paired and unpaired downlink component carriers configured for LTE-A user equipment; when LTE user equipment and LTE-A user equipment have the same physical layer downlink control channel to uplink ACK/NACK The timing relationship of the feedback, and when the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel, it refers to the unpaired downlink component carrier configured for the LTE-A user equipment; when the ACK of the LTE-A user equipment When the /NACK feedback adopts the PUCCH format 2/2a/2b channel, it refers to the paired and unpaired downlink component carriers configured for the LTE-A user equipment. the

In addition to broadcasting the first parameter, the second parameter, the third parameter and the fourth parameter of the paired uplink component carrier on each downlink component carrier, the base station also notifies the LTE-A user equipment of the dynamic ACK/NACK resource mapping of the carrier starting bias. Setting the same PUCCH format 1/1a/1b channel starting point at this time refers to setting the same PUCCH format 1/1a/1b channel for the LTE-A user equipment carrier that obtains PUCCH resources in an uplink component carrier and the paired downlink component carrier starting point. Because the first parameter, the second parameter, the third parameter and the fourth parameter broadcasted in the downlink paired component carrier can be received by both the LTE user equipment and the LTE-A user equipment, the second parameter and the fourth parameter notified by broadcasting The third parameter can set the same PUCCH format 1/1a/1b channel starting point for the LTE-A user equipment carrier and the paired downlink component carrier that obtains the PUCCH resource in one uplink component carrier. The specific method of notifying the dynamic ACK/NACK resource mapping start offset of the carrier to the LTE-A user equipment may be that the base station notifies each LTE-A user equipment of its carrier dynamic ACK/NACK resource mapping start offset; or the base station broadcasts the dynamic ACK/NACK resource mapping start offset of the LTE-A user equipment carrier, and further, broadcasts the notification in the paired downlink component carrier with the uplink component carrier Dynamic ACK/NACK resource mapping start offset of LTE-A user equipment carrier. the

When the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel, the starting offset of the dynamic ACK/NACK resource mapping of the carrier of the LTE-A user equipment may be corresponding to the uplink component carrier Each LTE-A user equipment carrier notifies a sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ , where N _{PUCCH_LTEA} ⁽¹⁾ indicates that the dynamic ACK/NACK resource of the LTE-A user equipment carrier is in all PUCCH format 1/1a/1b channels The starting offset of the mapping. As shown in FIG. 7, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ , and the fourth parameter N _PUCCH ⁽¹⁾ in the PUCCH resource configuration method according to the embodiment of the present invention and one of the schematic diagrams of the sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ (increased notification for each LTE-A user equipment carrier), in the figure, the fourth parameter N _PUCCH ⁽¹⁾ represents the dynamic ACK/NACK for the downlink component carrier Resource mapping start offset, the sixth parameter N _{PUCCH_LTEA, i} ⁽¹⁾ and N _{PUCCH_LTEA, i+1} ⁽¹⁾ respectively represent the dynamic ACK/NACK resources of the i-th and i+1-th LTE-A user equipment carriers Mapping start offset. Each downlink component carrier adopts an implicit mapping method of dynamic ACK/NACK resources similar to the 3GPP E-UTRA FDD system.

When the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel and the LTE-A user equipment also knows the system bandwidth of all LTE-A user equipment carriers corresponding to the uplink component carrier, the above LTE-A The dynamic ACK/NACK resource mapping start offset of the A user equipment carrier may be to notify a common sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ for all LTE-A user equipment carriers corresponding to the uplink component carrier, as shown in FIG. 8 Shown is the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ , the fourth parameter N _PUCCH ⁽¹⁾ and the sixth parameter in the method for configuring PUCCH resources in the embodiment of the present invention The second schematic diagram of N _{PUCCH_LTEA} ⁽¹⁾ , in the figure, the fourth parameter N _PUCCH ⁽¹⁾ represents the dynamic ACK/NACK resource mapping start offset for downlink component carriers, and the sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ represents all LTE - Dynamic ACK/NACK resource mapping start offset of A user equipment carrier. The implicit mapping of dynamic ACK/NACK resources similar to the 3GPP E-UTRA FDD system is adopted within the paired downlink component carriers, and the multi-subframe dynamic ACK/NACK resources similar to the 3GPP E-UTRA TDD system are adopted between LTE-A user equipment carriers Implicit mapping method.

When the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 2/2a/2b channel, the starting offset of the dynamic ACK/NACK resource mapping of the carrier of the LTE-A user equipment may be corresponding to the uplink component carrier The LTE-A user equipment notifies a seventh parameter N _PUCCH ⁽²⁾ again, wherein the seventh parameter N _PUCCH ⁽²⁾ indicates that the dynamic ACK/NACK resource of the LTE-A user equipment is mapped in all PUCCH format 2/2a/2b channels starting bias. As shown in FIG. 9, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ , and the fourth parameter N _PUCCH ⁽¹⁾ in the PUCCH resource configuration party in the embodiment of the present invention and the schematic diagram of the seventh parameter N _PUCCH ⁽²⁾ . In the figure, the dynamic ACK/NACK resource implicit mapping method similar to that of the 3GPP E-UTRA FDD system is adopted in the paired downlink component carriers, and the LTE-A user equipment carrier can also adopt a method similar to that of the 3GPP E-UTRA FDD system. - An implicit mapping method from the physical layer downlink control channel to the dynamic ACK/NACK resource in the UTRA system.

The base station can use the fourth parameter N _{PUCCH, i} ⁽¹⁾ to control whether the dynamic ACK/NACK mapping resources between multiple downlink component carriers that obtain PUCCH resources on the same uplink component carrier overlap each other. If dynamic ACK/NACK mapping is not performed The configurations do not overlap each other during resource compression, and the configurations overlap each other during dynamic ACK/NACK resource compression. All downlink component carriers that acquire PUCCH resources on the same uplink component carrier have the same PUCCH format 1/1a/1b channel mapping starting point. For the i-th component carrier, its dynamic ACK/NACK mapping resource is based on the fourth parameter N _{PUCCH, i} ⁽¹⁾ is the starting point of consecutive N _i ^maxCCE PUCCH format 1/1a/1b channels, where N _i ^maxCCE represents the maximum number of CCEs (Control Channel Elements) occupied by the PDCCH of the i-th component carrier; PUCCH resources other than ACK/NACK mapping resources are fully shared among these downlink component carriers.

When PUCCH resources other than dynamic ACK/NACK mapping resources are fully shared among multiple downlink component carriers, set the fourth parameter N _{PUCCH of the next component carrier of a component carrier, i+1} ⁽¹⁾ and the downlink component carrier When the difference between the fourth parameter N _PUCCH,i ⁽¹⁾ of the carrier is not less than the maximum number of control channel elements N _i ^maxCCE occupied by the component carrier, the dynamic ACK/NACK mapping resources of the downlink component carrier and the next downlink component carrier have no overlap each other. When PUCCH resources other than dynamic ACK/NACK mapping resources are fully shared among multiple downlink component carriers, set the fourth parameter N PUCCH of the next component carrier of a component carrier N _{PUCCH, i+1} ⁽¹⁾ and the downlink component carrier When the fourth parameter N _{PUCCH, i} ⁽¹⁾ difference of the carrier is less than the maximum number of control channel elements N _i ^maxCCE occupied by the downlink component carrier, the dynamic ACK/NACK mapping resources of the downlink component carrier and the next downlink component carrier have overlap each other.

Instantly $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}\&Greater\; Equal;N_i^{\max \mathrm{CCE}}$ When , the dynamic ACK/NACK mapping resources of the i-th downlink component carrier and the i+1-th downlink component carrier do not overlap each other; when $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}<N_i^{\max \mathrm{CCE}}$ , the dynamic ACK/NACK mapping resources of the i-th downlink component carrier and the i+1-th downlink component carrier overlap with each other. Therefore, the base station can easily use the fourth parameter N _{PUCCH, i} ⁽¹⁾ to control whether the dynamic ACK/NACK mapping resources of the i-th downlink component carrier and the i+1-th downlink component carrier overlap, thereby controlling whether to perform dynamic ACK/NACK mapping. ACK/NACK mapping resource compression.

Idle dynamic ACK/NACK resource blocks can be released for use by the physical layer uplink shared data channel. A better way is to configure the largest dynamic ACK/NACK mapping initial offset value for the component carrier with the largest system bandwidth, that is, configure the first For the four-parameter N _{PUCCH, i} ⁽¹⁾ takes the largest value.

As shown in Fig. 6, only dynamic ACK/NACK mapping resources are different among component carriers, and other PUCCH channel resources are shared among all component carriers. Considering that in the 3GPP E-UTRA system, except that the dynamic ACK/NACK channel is implicitly mapped through the PDCCH, the rest of the PUCCH channel resources are allocated to the user equipment by the base station through high-level signaling, so this part of the channel It is advantageous that resources are shared among all component carriers. the

For example, the load of the i-th component carrier is relatively light, so that the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by the PDCCH in each subframe cannot reach the maximum number of OFDM symbols that can be occupied. Assuming that the maximum number of OFDM symbols occupied by the PDCCH is N, in the 3GPP E-UTRA system, the value of N can be 3 or 4 according to the system bandwidth. According to the load condition of the component carrier, the base station can predict that the number of OFDM symbols occupied by the PDCCH in the next period of time will not exceed n, where 0<n≤N. When reserving dynamic ACK/NACK mapping resources for this component carrier, you can configure $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}=N_i^{\mathrm{no}},$ Where N _i ⁿ represents the number of CCEs when the PDCCH of the i-th component carrier occupies n OFDM symbols. In the system, if load balancing is not performed on each component carrier, then the above configuration can be performed on each component carrier separately, that is, each component carrier can have a different value of n; if load balancing is performed on each component carrier, then the above configuration can be It is the same for all component carriers, that is, all component carriers take the same value of n.

For example, the initial CCE occupied by the PDCCH can only be a multiple of M, and the fourth parameter N _PUCCH ⁽¹⁾ of adjacent component carriers with M equal bandwidths can be set to only have a constant difference, such as 1, offset; Or pair m1 large-bandwidth component carriers with m2 groups of small-bandwidth component carriers, where m1+m2≤M, and configure the fourth parameter N _PUCCH ⁽¹⁾ between the starting component carriers of different pairing groups. A constant, such as 1, offset, configures the fourth parameter N _PUCCH ⁽¹⁾ between adjacent small bandwidth component carriers in the paired group so that $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}=N_i^{\max \mathrm{CCE}}$ or $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}=N_i^{\mathrm{no}}.$ In the 3GPP E-UTRA system, the dynamic ACK/NACK resource label of the user equipment is obtained by mapping the initial CCE label occupied by its PDCCH according to certain rules. For example, in a frequency division duplex system, the dynamic ACK/NACK resource index is the sum of the initial CCE index of the PDCCH and the fourth parameter N _PUCCH ⁽¹⁾ . Assuming that there are two component carriers with equal bandwidth (denoted as component carrier i and i+1), the starting CCEs occupied by the PDCCH are limited to only even-numbered ones, and the base station can configure $N_{\mathrm{PUCCH},i+1}^{\left(1\right)}-N_{\mathrm{PUCCH},i}^{\left(1\right)}=1.$ Assuming that the bandwidths of the component carriers are not equal, the starting CCEs occupied by the PDCCH are limited to even-numbered ones, and the resource compression in Example 1 is not introduced at the same time, and at this time, a large-bandwidth component carrier i can be combined with a group of small-bandwidth component carriers Carriers {j1, j2} are paired for dynamic ACK/NACK mapping resource compression, the base station can configure $N_{\mathrm{PUCCH},i}^{\left(1\right)}-N_{\mathrm{PUCCH},j1}^{\left(1\right)}=1,$ $N_{\mathrm{PUCCH},j2}^{\left(1\right)}-N_{\mathrm{PUCCH},j1}^{\left(1\right)}={\mathrm{<figure-callout\; id="1"\; label="N\; j"\; filenames="H2009100014910E00011.png,H2009100014910E00012.png"\; state="\{\{state\}\}">N</figure-callout>}}_j^1.$

In addition to broadcasting and notifying the first parameter, the second parameter, the third parameter and the fourth parameter of the paired uplink component carrier on each downlink component carrier, the base station also needs to notify the LTE-A user equipment of the sixth parameter N _{PUCCH_LTEA} ^{(1 )} or the seventh parameter N _PUCCH ⁽²⁾ , the purpose of which is to inform the LTE-A user equipment of the dynamic ACK/NACK resource mapping start offset of the carrier. Considering that the dynamic ACK/NACK resource mapping of the LTE-A user equipment carrier only occurs in the LTE-A user equipment, this part of the dynamic ACK/NACK mapping rules may not consider the compatibility of the LTE user equipment. In order to reduce the dynamic ACK/NACK resource overhead of the LTE-A user equipment carrier, the dynamic ACK/NACK resource size reserved for the LTE-A user equipment carrier or the linear extension factor may be increased. When increasing the notification linear extension factor, the base station and LTE-A user equipment can calculate the reserved dynamic ACK/NACK resource size according to the maximum number of control channel elements corresponding to the system bandwidth of the LTE-A user equipment carrier; when LTE-A When the ACK/NACK feedback of the user equipment adopts the PUCCH format 2/2a/2b channel, the base station and the LTE-A user equipment can also calculate the reserved dynamic ACK/NACK resource size.

When the dynamic ACK/NACK resource mapping start offset of the LTE-A user equipment carrier is to notify a sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ for each LTE-A user equipment carrier corresponding to the uplink component carrier, add the notification The dynamic ACK/NACK resource size reserved for each LTE-A user equipment carrier, or increase the linear expansion factor of each LTE-A user equipment carrier, or increase the notification to all LTE components corresponding to the uplink component carrier - A user equipment carrier with the same linear spreading factor.

When the dynamic ACK/NACK resource mapping start offset of the LTE-A user equipment carrier is to notify a common sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ for all LTE-A user equipment carriers corresponding to the uplink component carrier, add the notification The total dynamic ACK/NACK resource size reserved, or increased to notify a common linear scaling factor.

The above-mentioned increase notification parameters of the dynamic ACK/NACK resource size reserved for each LTE-A user equipment carrier, and the resource size and linear extension factor of the increase notification can be sent through broadcast parameters or through high-level signaling dedicated to the user equipment send. the

Embodiment 1 of the PUCCH resource configuration method of the present invention uses the PUCCH of the 3GPP E-UTRA system, the base station sends the same first parameter N _RB ^HO , the second The second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ and the fourth parameter N _PUCCH ⁽¹⁾ are different, setting the same PUCCH format channel starting point and different dynamic ACK/NACK resources for multiple downlink component carriers The mapping start offset makes it possible to reserve PUCCH resources compatible with LTE user equipment for multiple downlink component carriers in one uplink component carrier, so it can support flexible PUCCH resource sharing and overhead compression of dynamic ACK/NACK mapping resources, and This enables the further evolution system of 3GPP E-UTRA to be better compatible with the 3GPP E-UTRA system.

Example two

In the above embodiments, except for the dynamic ACK/NACK mapping resources, the rest of the PUCCH resources are fully shared among all component carriers. Moreover, it is also possible to share the PUCCH resources other than dynamic ACK/NACK mapping resources by setting different second parameters N _RB ⁽²⁾ and/or third parameters N _CS ⁽¹⁾ , and it is also possible to use the fourth parameter N _PUCCH,i ⁽¹⁾ is used to control whether dynamic ACK/NACK mapping resources between multiple downlink component carriers overlap each other.

The method for configuring PUCCH resources in Embodiment 2 of the present invention is to set a different PUCCH format 1/1a/1b channel starting point for at least one of the multiple downlink component carriers, and set a different starting point for the downlink component carrier among the multiple downlink component carriers. Different dynamic ACK/NACK resource mapping start offset settings; wherein the multiple downlink component carriers acquire PUCCH resources in the same uplink component carrier. the

In the further evolution system of 3GPP E-UTRA, in order to be better compatible with LTE user equipment, it is still necessary to broadcast and notify the first parameter, the second parameter, the third parameter and the fourth parameter in the downlink component carrier compatible with LTE user equipment. These parameters are receivable by both the LTE user equipment and the LTE-A user equipment. the

From the perspective of the communication system, when the number of downlink component carriers in the system is greater than the number of uplink component carriers, all user equipment scheduled on multiple downlink component carriers must obtain PUCCH resources from the same uplink component carrier. Broadcast and notify different second parameter N _RB ⁽²⁾ and/or third parameter N _CS ⁽¹⁾ in multiple downlink component carriers that obtain PUCCH resources in the uplink component carrier to set different PUCCH format 1/1a/1b channel starting points , notify different fourth parameters N _PUCCH ⁽¹⁾ to set different dynamic ACK/NACK resource mapping start offsets.

As shown in FIG. 4 , it is one of the schematic diagrams of the uplink carrier and the downlink carrier in the PUCCH resource configuration method of the embodiment of the present invention. In the figure, the downlink carrier has four downlink component carriers, which are downlink component carrier 1 and downlink component carrier 2 respectively. , downlink component carrier 3 and downlink component carrier 4, the uplink component carrier has 3 uplink component carriers, namely uplink component carrier 1, uplink component carrier 2 and uplink component carrier 3, the arrow is the uplink component carrier where the PUCCH corresponding to the downlink component carrier is located Indicates that all users scheduled by downlink component carrier 3 and downlink component carrier 4 must obtain PUCCH resources in uplink component carrier 3, and notify different second parameters N _RB ^{(2 )} and/or the third parameter N _CS ⁽¹⁾ and different fourth parameter N _PUCCH ⁽¹⁾ can reserve the PUCCH compatible with LTE user equipment for the downlink component carrier 3 and the downlink component carrier 4 in the uplink component carrier 3 Resources, the second parameter N _RB ⁽²⁾ and the third parameter N _CS ⁽¹⁾ of these broadcast notifications, and the different fourth parameter N _PUCCH ⁽¹⁾ can be received by both the LTE user equipment and the LTE-A user equipment. In this case, each downlink component carrier only needs to notify the user equipment of a set of PUCCH resource configuration parameters through a broadcast message, that is, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , and the third parameter N _CS ^{( 1)} and the fourth parameter N _PUCCH ⁽¹⁾ .

As shown in Fig. 10, the first parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ and the fourth parameter N _PUCCH ⁽¹⁾ are the PUCCH resource configuration method according to the second embodiment of the present invention. A schematic diagram of , where N _RB,i ⁽²⁾ , N _CS,i ⁽¹⁾ and N _PUCCH,i ⁽¹⁾ represent the second parameter, the third parameter and the fourth parameter of the i-th downlink component carrier respectively. As can be seen from the figure, different second parameters N _RB,i ⁽²⁾ and N _RB,i+1 ⁽²⁾ and third parameters N _CS,i ⁽¹⁾ and N _CS,i+1 ⁽¹⁾ , the fourth parameter N _PUCCH,i ⁽¹⁾ and N _PUCCH,i+1 ⁽¹⁾ .

Further, regardless of whether the number of downlink component carriers in the system is equal to the number of uplink component carriers, an LTE user equipment can only identify one downlink component carrier and one uplink component carrier, and an LTE-A user equipment can identify n1 downlink component carriers and n2 uplink component carriers, wherein n1 downlink carriers and n2 uplink component carriers are configured by the base station for LTE-A user equipment, n1≥1, n2≥1, and n1 and n2 may not be equal. A downlink component carrier and an uplink component carrier that can be identified by an LTE user equipment are called a paired component carrier, otherwise it is called an unpaired component carrier. the

As shown in FIG. 6 , it is the second schematic diagram of the uplink carrier and the downlink carrier in the PUCCH resource configuration method of the embodiment of the present invention. The downlink carrier in the system has four downlink component carriers, which are downlink component carrier 1 and downlink component carrier 2 respectively. , downlink component carrier 3 and downlink component carrier 4, the uplink component carrier in the system has 4 uplink component carriers, which are uplink component carrier 1, uplink component carrier 2, uplink component carrier 3 and uplink component carrier 4, forming 4 pairs Component carriers (downlink component carrier 1 and uplink component carrier 1, downlink component carrier 2 and uplink component carrier 2, downlink component carrier 3 and uplink component carrier 3, downlink component carrier 4 and uplink component carrier 4). The hollow arrow in the figure indicates the indication of the uplink component carrier where the PUCCH corresponding to the downlink component carrier of the LTE user equipment is located, and the solid arrow indicates the indication of the uplink component carrier where the PUCCH corresponding to the downlink component carrier of the LTE-A user equipment is located. The base station also configures three downlink component carriers, namely, downlink component carrier 2, downlink component carrier 3, and downlink component carrier 4, and one uplink component carrier, namely, uplink component carrier 3, for a certain LTE-A user equipment. When the base station configures multiple downlink component carriers and multiple uplink component carriers for an LTE-A user equipment at the same time, the PUCCH resources of the multiple downlink component carriers of the user equipment can be distributed to multiple uplink component carriers for acquisition, or Collect and obtain from one uplink component carrier, which is called the uplink primary component carrier of the LTE-A user equipment. the

For LTE-A user equipment, the base station can configure multiple downlink component carriers to support higher data transmission rates, and the number of ACK/NACK bits fed back is more than that of LTE user equipment. The ACK/NACK feedback of the LTE-A user equipment may use the PUCCH format 1/1a/1b channel, or the PUCCH format 2/2a/2b channel. These two channel formats are already supported by the LTE user equipment, and the adoption of these two channel formats for the ACK/NACK feedback of the LTE-A user equipment can enable the LTE user equipment and the LTE-A user equipment to coexist better in the system. The timing relationship between the physical layer downlink control channel and the uplink ACK/NACK feedback of the LTE-A user equipment and the LTE user equipment may be the same or different. the

The LTE-A user equipment carrier is defined as follows: When the LTE user equipment and the LTE-A user equipment have different timing relationships from the physical layer downlink control channel to the uplink ACK/NACK feedback, and the ACK/NACK feedback of the LTE-A user equipment uses PUCCH For channel format 1/1a/1b, it refers to paired and unpaired downlink component carriers configured for LTE-A user equipment; when LTE user equipment and LTE-A user equipment have the same physical layer downlink control channel to uplink ACK/NACK The timing relationship of the feedback, and when the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel, it refers to the unpaired downlink component carrier configured for the LTE-A user equipment; when the ACK of the LTE-A user equipment When the /NACK feedback adopts the PUCCH format 2/2a/2b channel, it refers to the paired and unpaired downlink component carriers configured for the LTE-A user equipment. the

In addition to broadcasting the first parameter, the second parameter, the third parameter and the fourth parameter of the paired uplink component carrier on each downlink component carrier, the base station also notifies the LTE-A user equipment of the dynamic ACK/NACK resource mapping of the carrier starting bias. Because the first parameter, the second parameter, the third parameter and the fourth parameter broadcasted in the downlink paired component carrier can be received by both the LTE user equipment and the LTE-A user equipment, the second parameter and the fourth parameter notified by broadcasting With three parameters, the same PUCCH format 1/1a/1b channel starting point can be set for the LTE-A user equipment carrier and the paired downlink component carrier obtaining PUCCH resources in one uplink component carrier. For the LTE-A user equipment carrier, the starting point of the PUCCH format 1/1a/1b channel can be set to the starting point of the PUCCH format 1/1a/1b channel determined by the second parameter and the third parameter broadcast and notified in the paired downlink component carrier Different, at this time, the LTE-A user equipment should also be notified of the maximum number of resource blocks N _{RB, add} ⁽²⁾ and the PUCCH mixed resource blocks allocated to the PUCCH format that the carrier considers to be used to transmit the PUCCH format 2/2a/2b channel The number of cyclic shifts N _CS,add ⁽¹⁾ of the banner zero autocorrelation sequence of the 1/1a/1b channel. The specific method of notifying the dynamic ACK/NACK resource mapping start offset of the LTE-A user equipment carrier may be that the base station notifies each LTE-A user equipment of its ACK carrier separately through LTE-A user equipment-specific high-layer signaling Dynamic ACK/NACK resource mapping start offset and possible N _{RB, add} ⁽²⁾ and N _{CS, add} ⁽¹⁾ ; or the base station broadcasts the dynamic ACK/NACK resource mapping start offset of the LTE-A user equipment carrier And possible N _{RB, add} ⁽²⁾ and N _{CS, add} ⁽¹⁾ , further, broadcast the dynamic ACK/NACK resource mapping of LTE-A user equipment carrier in the paired downlink component carrier with the uplink component carrier Starting bias and possibly N _{RB, add} ⁽²⁾ and N _{CS, add} ⁽¹⁾ .

When the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel, the starting offset of the dynamic ACK/NACK resource mapping of the carrier of the LTE-A user equipment may be corresponding to the uplink component carrier Each LTE-A user equipment carrier notifies a sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ , where N _{PUCCH_LTEA} ⁽¹⁾ indicates that the dynamic ACK/NACK resource of the LTE-A user equipment carrier is in all PUCCH format 1/1a/1b channels The starting offset of the mapping. In addition, it is possible to notify one N _{RB, add} ⁽²⁾ and one N _{CS, add} ⁽¹⁾ for each LTE-A user equipment carrier, as shown in FIG. 7 , which is the first PUCCH resource configuration method in the embodiment of the present invention. One of the schematic diagrams of the parameter N _RB ^HO , the second parameter N _RB ⁽²⁾ , the third parameter N _CS ⁽¹⁾ , the fourth parameter N _PUCCH ⁽¹⁾ and the sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ , the figure does not notify N _{RB, add} ⁽²⁾ and N _{CS, add} ⁽¹⁾ . The fourth parameter N _PUCCH ⁽¹⁾ represents the dynamic ACK/NACK resource mapping start offset for downlink component carriers, and the sixth parameter N _{PUCCH_LTEA, i} ⁽¹⁾ and N _{PUCCH_LTEA, i+1} ⁽¹⁾ represent the i-th Dynamic ACK/NACK resource mapping start offset of the i-th and i+1-th LTE-A user equipment carriers. Each downlink component carrier adopts an implicit mapping method of dynamic ACK/NACK resources similar to the 3GPP E-UTRA FDD system.

When the ACK/NACK feedback of the LTE-A user equipment adopts the PUCCH format 1/1a/1b channel and the LTE-A user equipment also knows the system bandwidth of all LTE-A user equipment carriers corresponding to the uplink component carrier, the above LTE-A The dynamic ACK/NACK resource mapping start offset of A user equipment carrier may be to notify a common sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ for all LTE-A user equipment carriers corresponding to the uplink component carrier, and may further notify A common N _{RB, add} ⁽²⁾ and a common N _{CS, add} ⁽¹⁾ , as shown in FIG. 8, are the first parameter N _RB ^HO and the second parameter N in the method for configuring PUCCH resources in the embodiment of the present invention. The second schematic diagram _{of RB} ⁽²⁾ , the third parameter N _CS ⁽¹⁾ , the fourth parameter N _PUCCH ⁽¹⁾ and the sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ , in the figure, the fourth parameter N _PUCCH ⁽¹⁾ represents a pair The dynamic ACK/NACK resource mapping start offset of the downlink component carrier, the sixth parameter N _{PUCCH_LTEA} ⁽¹⁾ indicates the dynamic ACK/NACK resource mapping start offset of all LTE-A user equipment carriers. The implicit mapping of dynamic ACK/NACK resources similar to the 3GPP E-UTRA FDD system is adopted within the paired downlink component carriers, and the multi-subframe dynamic ACK/NACK resources similar to the 3GPP E-UTRA TDD system are adopted between LTE-A user equipment carriers Implicit mapping method.

As shown in Figure 10, N _{RB, i} ⁽²⁾ and N _{CS, i} ⁽¹⁾ configured for component carrier i indicate the actual number of resource blocks in the system that are only used to transmit PUCCH format 2/2a/2b , the number of cyclic shifts of the banner zero autocorrelation sequence assigned to the PUCCH format 1/1a/1b channel on the PUCCH mixed resource block; N _{RB, i} ⁽²⁾ and N _{CS, i} ⁽¹⁾ configured for component carrier i+1 ⁾ indicates that the number of resource blocks that are only used to transmit PUCCH format 2/2a/2b is greater than the actual value of the system by 1, and there is no PUCCH mixed resource block. Therefore, the real starting point of the PUCCH format 1/1a/1b channel configured in the uplink component carrier is the same as the starting point of the PUCCH format 1/1a/1b channel considered by the downlink component carrier i, and the PUCCH format 1/1b channel considered by the downlink component carrier i+1. The starting point of the 1a/1b channel is different from the number of PUCCH format 1/1a/1b channels corresponding to N _CS,i ⁽¹⁾ constant amplitude zero autocorrelation sequence cyclic shifts.

When the PUCCH resources other than the dynamic ACK/NACK mapping resources are only partially shared, the starting point of the PUCCH format 1/1a/1b channel considered by each component carrier may be different, which is different from the PUCCH format 1/1b channel actually configured by the system on the uplink component carrier. The actual starting point of the 1a/1b channel may also be different. For the i-th downlink component carrier, the starting offset N _{PUCCH, i} ⁽¹⁾ of its dynamic ACK/NACK resource mapping is indicated relative to N _{RB, i} ⁽²⁾ and N _{CS, i} ⁽¹⁾ The starting point of the PUCCH format 1/1a/1b channel is calculated. When using the fourth parameter N _{PUCCH, i} ⁽¹⁾ to control whether the dynamic ACK/NACK mapping resources between multiple downlink component carriers overlap each other, it is necessary to select a same N _{PUCCH, i} ⁽¹⁾ for all downlink component carriers The same PUCCH format 1/1a/1b channel reference starting point can usually select the real starting point of the PUCCH format 1/1a/1b channel configured by the uplink component carrier.

When PUCCH resources other than dynamic ACK/NACK mapping resources are shared among multiple downlink component carriers, set the fourth parameter N _{PUCCH of the next component carrier of a component carrier, i+1} ⁽¹⁾ and the fifth parameter N _i+1 ^{(1), the sum of delta} , and the fourth parameter N _{PUCCH of the downlink component carrier, i} ⁽¹⁾ and the fifth parameter N _i ^{(1), the difference between the sum of delta} is not less than the downlink component carrier When the maximum number of occupied control channel elements is N _i ^maxCCE , the dynamic ACK/NACK mapping resources of the downlink component carrier and the next downlink component carrier do not overlap each other; the fifth parameter is the difference between the channel starting point and the channel reference starting point. When PUCCH resources other than dynamic ACK/NACK mapping resources are partially shared among multiple downlink component carriers, set the fourth parameter N PUCCH of the next component carrier of a component carrier N _{PUCCH, i+1} ⁽¹⁾ and the fifth parameter The difference between the sum N _i+1 ^{(1), delta} , and the sum of the fourth parameter N _{PUCCH, i} ⁽¹⁾ and the fifth parameter N _i ^{(1), delta} of the downlink component carrier is smaller than the occupancy of the downlink component carrier When the maximum number of control channel elements N _i ^maxCCE , the dynamic ACK/NACK mapping resources of the downlink component carrier and the next downlink component carrier overlap each other; the fifth parameter is the difference between the channel starting point and the channel reference starting point.

That is, the starting point of the PUCCH format 1/1a/1b channel determined by its parameters N _RB,i ⁽²⁾ and N _CS,i ⁽¹⁾ of the i-th downlink component carrier and the selected PUCCH format 1/1a/1b channel reference The difference between the starting points is the fifth parameter (N _i ^{(1), delta} ) PUCCH format 1/1a/1b channels. As shown in Figure 10, the starting point of the PUCCH format 1/1a/1b channel configured in the uplink component carrier is selected as the reference starting point of the PUCCH format 1/1a/1b channel, then $N_i^{\left(1\right),\mathrm{delta}}=0,$ N _i+1 ^{(1), delta} is equal to the number of PUCCH format 1/1a/1b channels corresponding to N _{CS, i} ⁽¹⁾ constant amplitude zero autocorrelation sequence cyclic shifts. The base station uses the fourth parameter N _{PUCCH, i} ⁽¹⁾ to control whether the dynamic ACK/NACK mapping resources between multiple downlink component carriers overlap each other, when $(N_{\mathrm{PUCCH},i+1}^{\left(1\right)}+N_{i+1}^{\left(1\right),\mathrm{delta}})-(N_{\mathrm{PUCCH},i}^{\left(1\right)}+N_i^{\left(1\right),\mathrm{delta}})\&Greater\; Equal;N_i^{\max \mathrm{CCE}}$ When , the dynamic ACK/NACK mapping resources of the i-th downlink component carrier and the i+1-th downlink component carrier do not overlap each other; when $(N_{\mathrm{PUCCH},i+1}^{\left(1\right)}+N_{i+1}^{\left(1\right),\mathrm{delta}})-(N_{\mathrm{PUCCH},i}^{\left(1\right)}+N_i^{\left(1\right),\mathrm{delta}}){<N}_i^{\max \mathrm{CCE}}$ , the dynamic ACK/NACK mapping resources of the i-th downlink component carrier and the i+1-th downlink component carrier overlap with each other.

It is assumed that the load of the i-th component carrier is relatively light, so that the number of OFDM symbols occupied by the PDCCH in each subframe does not reach the maximum number of OFDM symbols that can be occupied. Note that the maximum number of OFDM symbols occupied by the PDCCH is N. In the 3GPP E-UTRA system, the bandwidth N can be 3 or 4 according to system requirements. According to the load condition of the component carrier, the base station can predict that the number of OFDM symbols occupied by the PDCCH in the next period of time will not exceed n, where 0<n≤N. Then when reserving dynamic ACK/NACK mapping resources for this component carrier, you can configure $(N_{\mathrm{PUCCH},i+1}^{\left(1\right)}+N_{i+1}^{\left(1\right),\mathrm{delta}})-(N_{\mathrm{PUCCH},i}^{\left(1\right)}+N_i^{\left(1\right),\mathrm{delta}})=N_i^{\mathrm{no}},$ Where N _i ⁿ represents the number of CCEs when the PDCCH of the i-th component carrier occupies n OFDM symbols. In the system, if load balancing is not performed on each component carrier, then the above configuration can be performed on each component carrier separately, that is, each component carrier can have a different value of n; if load balancing is performed on each component carrier, then the above configuration can be It is the same for all component carriers, that is, all component carriers take the same value of n.

For example, the initial CCE occupied by the PDCCH can only be a multiple of M, and the fourth parameter N _PUCCH ⁽¹⁾ of adjacent component carriers of M equal bandwidths can be set to only have a constant difference, such as 1, offset; Or pair m1 large-bandwidth component carriers with m2 groups of small-bandwidth component carriers, where m1+m2≤M, and configure the fourth parameter N _PUCCH ⁽¹⁾ between the starting component carriers of different pairing groups. A constant, such as 1, offset, configures the fourth parameter N _PUCCH ⁽¹⁾ between adjacent small bandwidth component carriers in the paired group so that $(N_{\mathrm{PUCCH},i+1}^{\left(1\right)}+N_{i+1}^{\left(1\right),\mathrm{delta}})-(N_{\mathrm{PUCCH},i}^{\left(1\right)}+N_i^{\left(1\right),\mathrm{delta}})=N_i^{\max \mathrm{CCE}}$ or $(N_{\mathrm{PUCCH},i+1}^{\left(1\right)}+N_{i+1}^{\left(1\right),\mathrm{delta}})-(N_{\mathrm{PUCCH},i}^{\left(1\right)}+N_i^{\left(1\right),\mathrm{delta}})=N_i^{\mathrm{no}}.$ In the 3GPP E-UTRA system, the dynamic ACK/NACK resource label of the user equipment is obtained by mapping the initial CCE label occupied by its PDCCH according to certain rules.
