Description

User equipment, access network equipment, method and device for transmitting and receiving uplink control information

Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a user equipment, an access network device, and a method and device for transmitting and receiving uplink control information.

Background technique

In the communication system, the user equipment (User Equipment, UE) needs to send uplink control information (UCI) to the access network device. The UE sends the UCI through the uplink channel resource indicated by the access network device.

In a carrier aggregation (CA) scenario, an access network device simultaneously transmits downlink data to a UE by using multiple carriers, where the multiple carriers include one primary carrier and multiple secondary carriers. At the same time, the UE needs to feed back the UCI to the access network device for the multiple carriers. When the UE feeds back the UCI, the UE needs to select the uplink channel resource used this time from among the four uplink channel resources that are pre-configured. The method for the UE to select the uplink channel resource includes: the UE reads the information carried in the predetermined bit from the Downlink Control Information (DCI) in the physical downlink control channel (PDCCH) of the multiple secondary carriers. The information determines the uplink channel resource used this time according to the information carried on the predetermined bit. The predetermined bit may be a bit corresponding to a physical uplink control channel transmit power control command (Transmisson Power Contral Command for Physical Uplink Control Channel, TPC Command for PUCCH). The predetermined bit in the downlink control information of the plurality of secondary carriers carries the same information, and the predetermined bit is usually represented by 2 bits.

For example, when the information carried on the predetermined bit is 00, the UE transmits the UCI by using the first uplink channel resource; when the information carried on the predetermined bit is 01, the UE transmits the UCI by using the second uplink channel resource; When the information carried on the bit is 10, the UE transmits the UCI by using the third uplink channel resource; when the information carried on the predetermined bit is 11, the UE transmits the UCI by using the fourth uplink channel resource.

In the process of implementing the embodiments of the present invention, the inventor has found that at least the following problems exist in the prior art: in the carrier aggregation scenario, there may be many uplink channel resources for the UCI to be pre-configured by the access network device to the UE, such as 16 or 32. For example, if the pre-configured uplink channel resource is 16, the access network device needs to modify the predetermined bit from 2 bits to log ₂ 16=4 bits before indicating to the UE the uplink channel resource used this time. Will cause a large transmission load on the PDCCH channel.

detailed description

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

In the CA scenario, the access network device can send downlink data to the UE through one primary carrier and multiple secondary carriers. For each carrier that transmits downlink data to the UE, the access network device sends the DCI corresponding to the downlink data to the UE through the PDCCH. The information carried in the DCI includes: physical downlink sharing. Resource indication information of the Physical Downlink Shared Channel (PDSCH), Downlink Assignment Index (DAI), and TPC command for PUCCH.

The resource indication information of the PDSCH is used to inform the UE which resources in the PDSCH of the carrier to receive downlink data. The DAI is used to inform the UE of the count value of the PDSCH in all PDSCHs sent to the UE. For example, if there are X PDSCHs transmitted to the UE, the count value is the current PDSCH is the PDSCH of the X PDSCHs.

For example, in a Frequency Division Dual (FDD) system, there are downlink data transmitted by the UE on M carriers in a Transmission Time Interval (TTI), and it is assumed that the M carriers correspond to each other. the carrier number from small to large are _{_{N 0, N 1, ...... N}} M-1, the count value of the DAI DCI downlink data on the M carriers each corresponding PDCCH transmission channel indicated by the following sequentially carrier number Sort. For example, the count value indicated by the DAI in the DCI corresponding to the downlink data corresponding to the downlink data transmitted on the carrier with the carrier number of N ₁ is 0, and the PDCCH channel corresponding to the downlink data sent on the carrier whose carrier number is N ₁ The count value indicated by the DAI in the DCI is 1, and the count value indicated by the DAI in the DCI in the PDCCH channel corresponding to the downlink data transmitted on the carrier whose carrier number is N _M-1 is M-1.

For example, in a Time Division Duplexing (TDD) system, each of the downlink sub-frames corresponding to the LTIs on one uplink feedback has multiple carriers transmitting downlink data to the UE, The count values indicated by the DAI of the DCI in the PDCCH channel corresponding to the downlink data transmitted on the plurality of carriers of the L downlink subframes are first sorted according to the carrier sequence number, and then sorted according to the subframe sequence number. Taking L=2 as an example, it is assumed that downlink data transmitted by the UE exists on the M carriers of the first subframe, and downlink data transmitted to the UE exists on the K carriers of the second subframe. Counting the number of the first sub-carrier downlink data frame is transmitted on a carrier corresponding to the N ₁ in the PDCCH DCI channel DAI indicated value of 0, the first sub-carrier number of the carrier frame of N ₁ The count value indicated by the DAI in the DCI in the PDCCH channel corresponding to the uplink and downlink data is 1, ... the DCI in the PDCCH channel corresponding to the downlink data sent on the carrier with the carrier number of the first subframe is N _M-1 The count value indicated by the DAI in the DAI is M-1, and the count value indicated by the DAI in the DCI in the PDCCH channel corresponding to the downlink data transmitted on the carrier whose carrier number is N ₁ in the second subframe is M, and the second The count value indicated by the DAI in the DCI of the PDCCH channel corresponding to the downlink data transmitted on the carrier whose carrier number is N ₂ is the M+1, ... the carrier number of the second subframe is N _K-1 The count value indicated by the DAI in the DCI in the PDCCH channel corresponding to the downlink data transmitted on the carrier is M+K-1.

The UE may receive downlink data according to resource indication information of the PDSCH. The UE may further determine, according to the indication of the DAI, whether there is a downlink data that is not received by the access network device. For each downlink data, if the UE successfully receives the downlink data, it generates an acknowledgement (ACK) message, and if the UE fails to successfully receive the downlink data, generates a non-acknowledgement (NACK) message, that is, a hybrid automatic repeat request. (Hybrid Automatic Repeat Request, HARQ) mechanism. The ACK information and the NACK information may be collectively referred to as HARQ-ACK, that is, hybrid automatic repeat request feedback.

In addition, the UE also needs to report periodic channel state information (CSI) of each downlink carrier that is in an active state to the access network device. The time at which the UE needs to transmit the periodic CSI information of each carrier is determined according to the pre-configuration information of the periodic CSI of each carrier by the access network device.

The UCI includes: HARQ-ACK and periodic CSI. To support the UE to transmit UCI on a specific uplink subframe, the access network device pre-configures four uplink channel resources for the UE. On the current subframe, the UE needs to determine an uplink channel resource for transmitting uplink control information in the current subframe from the four uplink channel resources. Optionally, the uplink channel resource is a PUCCH resource.

It should be noted that the information “TPC command for PUCCH” carried by the DCI of the PDCCH channel of all the secondary carriers used for transmitting the PDSCH to the UE in the downlink subframe corresponding to the current subframe is in the pre-configured four The uplink channel resources used in the current subframe are determined in the uplink channel resources. The "TPC command for PUCCH" in the DCI of these PDCCH channels carries the same information. At the same time, the UE determines the transmission power used for transmitting the PUCCH channel of the UCI by using the “TPC command for PUCCH” carried in the DCI of the PDCCH channel corresponding to the PDSCH on the primary carrier.

However, in some CA scenarios involved in the embodiments of the present invention, the access network device may configure more carriers for the UE to send downlink data, for example, up to 16 carriers or 32 carriers. At this time, the HARQ-ACK information that the UE needs to feed back on the current subframe is determined by the number of carriers that transmit downlink data for the UE in the downlink subframe corresponding to the current subframe. Since the number of carriers that transmit downlink data for the UE in each downlink subframe varies between a plurality of carriers, the data amount of the HARQ-ACK information transmitted by the UE varies in a different uplink subframe. At the same time, according to the pre-configuration information of the periodic CSI of the access network device, the UE also needs to send a different number of periodic CSIs in different uplink subframes, so the UE sends in different uplink subframes. The data amount of the periodic CSI information also varies widely. In short, the amount of data of the UCI that the UE needs to transmit in different uplink subframes is relatively large.

To accommodate the UCI feedback requirements of different data volumes, the access network device pre-configures more uplink channel resources, such as 16 or 32, to the UE. The "TPC command for PUCCH" control bit of the DCI in the PDCCH is only 2 bits, which is insufficient to indicate to the UE, for determining the uplink channel resource used in the current subframe in the pre-configured multiple uplink channel resources. If the number of bits occupied by the TPC command for PUCCH control bit is increased, the PDCCH will impose a large burden on the PDCCH.

Please refer to FIG. 4, which is a flowchart of a method for transmitting and receiving uplink control information according to an exemplary embodiment of the present invention. This embodiment is applied to the communication system shown in FIG. 1 by the method, and the method includes:

Step 401: The access network device determines resource indication information, where the resource indication information includes at least two fields.

The resource indication information is used to indicate that the UE determines an uplink channel resource for sending uplink control information in the pre-configured uplink channel resource set. In an LTE system, the uplink channel resource refers to a PUCCH resource having a specific PUCCH format and a specific time-frequency location. Optionally, all or part of the pre-configured uplink channel resources further include: attribute information that supports the maximum number of transmitted bits of the UCI, and the maximum coding rate that can be used when transmitting the UCI.

Optionally, the resource indication information may also be referred to as another name, such as channel indication information, channel identifier information, or resource identifier information, which is not limited in this embodiment.

The resource indication information includes M fields, each of which includes the same number of bits or a different ratio Special number, M ≥ 2. For example, the resource indication information includes three fields, each of which includes 2 bits, that is, the resource indication information includes a total of 6 bits.

Step 402: The access network device sends each field to the UE by using DCI in one PDCCH set, and each PDCCH set includes a plurality of PDCCHs for scheduling the UE to receive downlink data in the secondary carrier.

In the CA scenario, the access network device configures multiple downlink carriers for the UE, for example, configuring 16, 32, or more downlink carriers for the UE. These downlink carriers include one primary carrier and multiple secondary carriers.

The access network device divides the PDCCH for scheduling the UE to receive downlink data in multiple secondary carriers into M PDCCH sets, and each PDCCH set is used to send one field in the resource indication information.

For example, the auxiliary PDCCH is 9 and the resource indication information includes three fields. The access network device divides the three PDCCHs with the count value indicated by the DAI with respect to the remainder of 3 into the first PDCCH set, and is used for transmitting resources. The first field in the indication information; the three PDCCHs that have the count value indicated by the DAI with respect to the remainder of 3 are divided into two PDCCH sets for transmitting the second field in the resource indication information; The three PDCCHs whose count value is 0 with respect to the remainder of 3 are divided into a third PDCCH set for transmitting the third field in the resource indication information, as shown in FIG. 5.

It should be noted that the fields of the resource indication information carried in the DCI of each PDCCH in the same PDCCH set are the same. For example, the first field in the resource indication information is carried in the three DCIs of the three PDCCHs whose count value indicated by the DAI is 0 with respect to the remainder of 3.

Step 403: The UE determines resource indication information, where the resource indication information includes at least two fields, each field is determined by DCI in one PDCCH set, and each PDCCH set includes several PDCCHs corresponding to downlink data received in the secondary carrier. ;

The UE receives multiple DCIs that are sent by the access network device through multiple PDCCH sets, and the UE determines each field in the resource indication information from the DCI in each PDCCH set, and finally determines the resource indication information.

Step 404: The UE determines an uplink channel resource corresponding to the resource indication information in the pre-configured uplink channel resource set.

The pre-configured uplink channel resource set includes at least two PUCCH resources, and the UE uses one of the PUCCH resources to send the UCI to the access network device.

The UE determines an uplink channel resource corresponding to the resource indication information from the pre-configured uplink channel resource set.

Step 405: The UE sends the UCI on the uplink channel resource corresponding to the resource indication information.

Step 406: The access network device receives the UCI sent by the UE on the uplink channel resource corresponding to the resource indication information.

In summary, the method for transmitting and receiving uplink control information provided in this embodiment is to divide resource indication information into at least two fields, each field being carried by DCI in one PDCCH set, and each PDCCH set includes a secondary carrier of the UE. A plurality of PDCCHs corresponding to the received data; when the pre-configured uplink channel resources are many, the access network device needs to increase the bits occupied by the predetermined bits to indicate to the UE that the UCI is used to transmit the UCI in the current subframe. The problem of the uplink channel resource of the information; the access network device does not need to increase the bit occupied by the predetermined bit, and the DCI in each of the multiple PDCCH sets respectively indicates a field of the resource indication information to the UE, On the UE side, the UE obtains resource indication information by determining each field of the resource indication information, and then accurately determines the effect of transmitting the uplink channel resource used by the UCI in the current subframe.

In an optional embodiment provided by the embodiment of FIG. 4, the resource indication information includes M fields, M≥2, that is, M is an integer greater than or equal to 2, and the physical downlink control channel set is M. The i-th field in the resource indication information is determined by information carried on a predetermined bit in the downlink control information in the j-th physical downlink control channel set in the M physical downlink control channel set, where i and j There is a preset correspondence between them.

For example, the resource indication information includes 4 fields, and each field contains 2 bits. There are also four PDCCH sets, and the first field in the resource indication information is determined by the information carried in the predetermined bit in the DCI in the first PDCCH set; the second field in the resource indication information is the second field. Determining information carried on a predetermined bit in the DCI in the PDCCH set; the third field in the resource indication information is determined by information carried on a predetermined bit in the DCI in the third PDCCH set; resource indication information The fourth field in the field is determined by the information carried on the predetermined bit in the DCI in the 4th PDCCH set.

For another example, the resource indication information includes three fields, each of which contains 2 bits. The PDCCH set is also three, and the first field in the resource indication information is determined by the information carried on the predetermined bit in the DCI in the second PDCCH set; the second field in the resource indication information is the third field. The information carried on the predetermined bit in the DCI in the PDCCH set is determined; the third field in the resource indication information is determined by the information carried on the predetermined bit in the DCI in the first PDCCH set.

In an alternative embodiment provided based on the embodiment of FIG. 4, it is assumed that the access network device configures one primary carrier and N secondary carriers for the UE. The access network device and the UE need to divide the N PDCCHs corresponding to the N secondary carriers according to a predetermined division policy to obtain M PDCCH sets, where 1≤M≤N. Optionally, the predetermined splitting strategy is: dividing the PDCCHs with the same remainder into the same PDCCH set according to the remainder of the count value indicated by the DAI in the DCI carried in each PDCCH with respect to M.

For example, the count value indicated by the DAI in the first PDCCH is 0, the count value indicated by the DAI in the second PDCCH is 1, and the count value indicated by the DAI in the third PDCCH is 2, the fourth The count value indicated by the DAI in the PDCCH is 3, and the count value indicated by the DAI in the 5th PDCCH is 4. If M=2, the count value indicated by the DAI in the first PDCCH, the third PDCCH, and the fifth PDCCH is 0 with respect to the remainder of 2, and is divided into the first PDCCH set; the second PDCCH and the The count value indicated by the DAI in the four PDCCHs is 1 with respect to the remainder of 2, and is divided into the second PDCCH set.

It should be noted that the partitioning strategy is not limited to one of the foregoing division manners, as long as the access network device and the UE adopt the same division strategy.

It is to be noted that the PDCCH in each PDCCH set is at least one, and the number of PDCCHs in different PDCCH sets is the same or different, which is not limited in this embodiment.

It should be noted that the information carried in the predetermined bits of the DCI in the PDCCH in each PDCCH set is the same, and the information carried in the predetermined bits of the DCI in the PDCCH in different PDCCH sets is the same or different. The embodiment does not limit this.

Optionally, the predetermined bit is a bit occupied by "TPC Command for PUCCH" in the DCI in the PDCCH, and usually occupies 2 bits.

In an optional embodiment provided by the embodiment of FIG. 4, the UE receives the DCI in at least one PDCCH channel in the PUCCH set for the PDCCH set corresponding to each field of the resource indication information, and the foregoing implementation is performed. Step 404 in the example can be implemented as step 404a instead. As shown in Figure 6:

Step 404a: The UE determines an uplink channel resource corresponding to the resource indication information in the pre-configured uplink channel resource set according to the first correspondence, where the first correspondence is preset resource indication information and each of the uplink channel resource set. Correspondence between uplink channel resources;

The resource indication information includes 2 fields, a total of 4 bits, and the access network device is pre-configured for the UE. Taking 16 PUCCH resources as an example, Table 1 exemplarily shows the first correspondence:

资源指示信息Resource indication information	上行信道资源Upstream channel resource
00000000	第1个上行信道资源First uplink channel resource
00010001	第2个上行信道资源2nd uplink channel resource
00100010	第3个上行信道资源Third uplink channel resource
…...	…...
11111111	第16个上行信道资源16th uplink channel resource

Table I

For each PUCCH resource that is configured by the access network device for the UE, the pre-configuration information includes attribute information such as a resource format and a time-frequency location of the PUCCH resource. Optionally, the pre-configuration information further includes attribute information such as a maximum number of transmission bits of the PUCCH resource and/or a maximum coding rate that can be used by the UCI. The maximum number of transmitted bits refers to the maximum number of transmitted bits that support the transmission of UCI.

If the resource indication information determined by the UE is 0001, the uplink channel resource corresponding to the 0001 is the second uplink channel resource, and the resource format and the time-frequency location corresponding to the uplink channel resource may be determined. Optionally, it is also possible to determine the maximum number of transmitted bits of the uplink channel resource to support transmission of UCI, and/or the maximum coding rate that can be used when transmitting UCI.

Correspondingly, the UE sends the UCI on the uplink channel resource corresponding to the resource indication information.

In summary, the embodiment of the present invention determines the uplink channel resource corresponding to the resource indication information by using the first correspondence, and has the advantages of simple correspondence, small calculation amount, and fast calculation speed.

In an optional embodiment provided based on the embodiment of FIG. 4, the pre-configured uplink channel resource set includes two or more sets, and the UE may determine each uplink channel resource set in the pre-configured uplink channel resource set. The uplink channel resource supports the maximum number of bits for transmitting UCI. The maximum number of bits corresponding to each of the pre-configured uplink channel resource sets that support the transmission of the UCI may be configured to the UE by using the high layer signaling, or may be determined by the UE by using the resource format in each uplink channel resource set. For example, the uplink channel resources in the uplink channel resource set are all a set of PUCCH format 3, and the maximum number of bits supporting the transmission of UCI is 22. The manner in which the UE determines that the uplink channel resource in the pre-configured uplink channel resource set supports the maximum number of bits of the UCI is not limited.

Correspondingly, the resource indication information includes: first indication information and second indication information. The first indication information is used to determine a first uplink channel resource set in two or more sets of the pre-configured uplink channel resource set, and the second indication information is used to determine an uplink channel in the first uplink channel resource set. the resources for uplink channel resources used to transmit the UCI, corresponding to the resource indication information field of R _1, R ₁ ≥1; second indication information corresponding to the instruction information resource R ₂ fields, R ₂ ≥1 . If the resource indication information includes K bits, the first indication information is composed of A bits, and the second indication information is composed of KA bits. At this time, step 404 in the above embodiment may be implemented instead as step 404b and step 404c. As shown in Figure 7:

Step 404b: The UE determines, according to the second correspondence, the uplink channel resource set corresponding to the first indication information, as the first uplink channel resource set, in the plurality of pre-configured uplink channel resource sets.

The second correspondence is a correspondence between the preset first indication information and the pre-configured at least two uplink channel resource sets. Taking the first indication information as 2 bits as an example, Table 2 exemplarily shows the second correspondence:

第一指示信息First indication	上行信道资源集合Upstream channel resource set
0000	预配置的上行信道资源集合中的第1个上行信道资源集合The first uplink channel resource set in the pre-configured uplink channel resource set
0101	预配置的上行信道资源集合中的第2个上行信道资源集合The second uplink channel resource set in the pre-configured uplink channel resource set
1010	预配置的上行信道资源集合中的第3个上行信道资源集合The third uplink channel resource set in the pre-configured uplink channel resource set
1111	预配置的上行信道资源集合中的第4个上行信道资源集合The fourth uplink channel resource set in the pre-configured uplink channel resource set

Table II

The PUCCH format X may be any possible PUCCH format, such as the PUCCH format 6 that appears in the future.

Optionally, the resource formats of the first uplink channel resource set, the second uplink channel resource set, the third uplink channel resource set, and the fourth uplink channel resource set are respectively PUCCH format 3 and PUCCH. Format 4, PUCCH format 5, PUCCH format X. The PUCCH format X may be any possible PUCCH format, such as the PUCCH format 6 that appears in the future.

If the resource indication information determined by the UE is 0100, where the first indication information includes a field, which is the first two bits in the resource indication information, the uplink channel resource set corresponding to the first indication information 01 is the second uplink channel. The set of resources, that is, the first uplink channel resource set is the second uplink channel resource set.

Step 404c: The UE determines, according to the third correspondence, the uplink channel resource corresponding to the second indication information in the first uplink channel resource set.

The third correspondence is a correspondence between the preset second indication information and each uplink channel resource in the first uplink channel resource set. Taking the second indication information including 2 bits as an example, Table 3 is exemplary. The third correspondence is shown:

第二指示信息Second indication	第一上行信道资源集合First uplink channel resource set
0000	第1个上行信道资源First uplink channel resource
0101	第2个上行信道资源2nd uplink channel resource
1010	第3个上行信道资源Third uplink channel resource
1111	第4个上行信道资源4th uplink channel resource

Table 3

If the resource indication information determined by the UE is 0100, where the second indication information includes a field, which is the last two bits in the resource indication information, the uplink channel resource corresponding to the second indication information 00 is the first uplink channel resource set. The first uplink channel resource, that is, the uplink channel resource corresponding to the resource indication information, is the first uplink channel resource in the second uplink channel resource set.

In summary, the pre-configured uplink channel resource set in the embodiment of the present invention is composed of at least two sets, and the maximum number of bits corresponding to the uplink transmission channel corresponding to each of the at least two sets is different. The UE may determine, according to the first indication information and the second indication information, that the uplink channel resource in the uplink channel resource set sends the UCI, thereby improving the utilization efficiency of the uplink channel resource.

The PDCCH in the PDCCH sent by the access network device has the possibility of receiving failure on the UE side. The UE may successfully receive the PDCCH corresponding to the downlink data on the scheduled secondary carrier, but the PDCCH is not successfully received. The scenario of the PDCCH corresponding to the downlink data on the other part of the secondary carrier. In this scenario, if the UE does not detect downlink control information on all physical downlink control channels in the Rth physical downlink control channel set corresponding to the Lth field in the resource indication information, the resource indication information The L fields are determined by predetermined rules. The predetermined rule includes: the information of the Lth field is a predetermined value, or the information of the Lth field is the downlink control information received on the physical downlink control channel in the Rth physical downlink control channel set. The information indicated on the bit, 1 ≤ L ≤ M, 1 ≤ R ≠ R' ≤ M, and R has a predetermined correspondence relationship with R'.

That is, step 403 in the above embodiment may be implemented instead as step 403a and step 403b. As shown in Figure 8:

Step 403a: The UE determines at least one field in the resource indication information, where each of the at least one field is determined by a DCI in a PDCCH set corresponding to the field, where each PDCCH set includes a received in a secondary carrier. a number of PDCCHs corresponding to the data;

For example, the resource indication information includes two fields, and the UE determines the first field of the resource indication information according to the predetermined bit bit 01 in the downlink control information in the PDCCH in the first PDCCH set, but the second field of the UE in the resource indication information No downlink control information is detected on all PDCCHs in the corresponding second PDCCH set.

In step 403b, the UE determines the information of the Lth field in the resource indication information, and the UE does not detect the DCI on all the PDCCHs in the PDCCH set corresponding to the Lth field, and the UE determines that the information of other fields is a preset value. Alternatively, the UE determines that the information of the Lth field is the information indicated on the predetermined bit in the DCI received on the PDCCH in the Rth PDCCH set, and there is a preset correspondence between R and R′.

For example, the UE determines that the information of the second field is a predetermined value, and the predetermined value is 01.

For another example, the UE determines that the information of the second field is the information 01 received by the predetermined bit in the downlink control information of the PDCCH in the first PDCCH set, and finally the UE determines that the resource indication information is 0101.

In summary, the embodiment of the present invention provides a method for determining resource indication information for a scenario in which all UEs in the PDCCH set corresponding to the partial field of the resource indication information are not correctly received by the UE, so that even a partial field is obtained. All the PDCCHs in the corresponding PDCCH set are not correctly received by the UE, and the UE can still determine these fields of the resource indication information, thereby determining the resource indication information, and then determining the effect of transmitting the uplink channel resources of the UCI.

Optionally, when the total number of carriers having downlink data in the secondary carrier is small, the total number of PDCCHs corresponding to the downlink data in the secondary carrier is small, and the UE does not correctly receive the PDCCH set corresponding to the partial field of the resource indication information. All PDCCHs are more likely. At this time, each field in the resource indication information determined by the access network device is the same, so that the UE determines that the resource indication information after the partial field is the same as the resource indication information sent by the access network device based on the predetermined rule.

Optionally, in the first correspondence shown in step 404a, the resource indication information that is the same for each field, the corresponding uplink channel resource is a channel resource with PUCCH format 3, or the step 404c is shown. In the third correspondence, for the second indication information that the information of each field is the same, the corresponding uplink channel resource is a channel resource with PUCCH format 3.

It should be noted that the PUCCH format 3, format 4, and format 5 described in this application are specifically:

PUCCH format 3: The original bit channel coded and modulated symbols are placed in two slots of one subframe, respectively. Thus, there are 12 modulation symbols on each time slot, and the 12 modulation symbols are placed on 12 consecutive subcarriers on one time domain symbol of one slot, ie occupying one resource block. 12 subcarriers on a time domain symbol in (Resource Block, RB). Then, for each time slot, the Orthogonal Cover Code (OCC) of length 5 is spread by the sequence w in the time domain, and one time slot occupies 5 time domain symbols in one RB, and different UEs The code division multiplexing can be performed on different RBs by using one orthogonal code, and the other two symbols are used to carry a reference signal (Reference Signal, RS). Then, Discrete Fourier Transform (DFT) precoding and Inverse Fast Fourier Transform (IFFT) are performed on the spread spectrum. In addition, the second time slot of the subframe in which the sounding reference signal is configured is code-multiplexed by using an orthogonal code of length 4, that is, at most 4 UE multiplexing is supported (the PUCCH format at this time is shortened PUCCH format). 3, and non-shortened PUCCH format 3 are collectively referred to as PUCCH format 3).

PUCCH format 4: The PUCCH channel occupies one RB or multiple RBs, and in the case of a normal Cyclic Prefix (normal CP), only one intermediate time domain symbol bearer demodulation reference is included in each slot corresponding to the PUCCH channel. a signal, in the case of an Extended Cyclic Prefix (Extended Cyclic Prefix), the third time domain symbol of each time slot carries a demodulation reference signal; the uplink control information is encoded according to a convolutional code coding manner and The PUCCH channel transmits; or the maximum number of bits of uplink control information that can be carried by the PUCCH channel is greater than 22 bits.

PUCCH format 5: The PUCCH channel occupies one RB, and in the case of a normal cyclic prefix, only one intermediate time domain symbol carries a demodulation reference signal in each slot corresponding to the PUCCH channel, in the case of extending the cyclic prefix, each The third time domain symbol of the time slot carries the demodulation reference signal, and the uplink control information of at least two UEs may be sent in the PUCCH channel by using a code division manner; the uplink control information is encoded according to the convolutional code coding manner and is in the PUCCH channel. Medium transmission; or the maximum number of bits of uplink control information that can be carried by the PUCCH channel is greater than 22 bits.

Please refer to FIG. 9 , which is a flowchart of a method for transmitting and receiving uplink control information according to another embodiment of the present invention. This embodiment is exemplified by applying the method for transmitting and receiving the uplink control information to the communication system shown in FIG. 1. This embodiment also exemplifies a scenario in which an access network device uses multiple carriers to transmit downlink data to a UE. The method includes:

Step 901: The access network device sends resource indication information to the UE.

The resource indication information is used to indicate that the UE determines an uplink channel resource for transmitting the UCI in the pre-configured uplink channel resource set. In an LTE system, the uplink channel resource refers to a PUCCH resource having a specific PUCCH format and a specific time-frequency location. Optionally, all or a part of the pre-configured uplink channel resources further includes: a maximum number of transmission bits supporting the transmission of the UCI, and sending Attribute information such as the maximum encoding rate that can be used when sending UCI.

The resource indication information may include only one field, or the resource indication information includes two or more fields. When the resource indication information includes only one field, the access network device may send the resource indication information to the UE by using a sending method as shown in the background technology; when the resource indication information includes two or more fields, The access network device may send the resource indication information to the UE by using the sending method provided in the embodiment shown in FIG. 4, which is not limited in this embodiment.

Correspondingly, the UE determines the resource indication information according to a preset field in the received physical downlink control channel or determines each field in the resource indication information.

Step 902: The UE determines a UCI of the first uplink subframe, where the UCI includes a HARQ-ACK and a periodic CSI.

The UE may determine, according to the received downlink data, and the timing relationship between the multiple downlink data and the corresponding HARQ-ACK, whether the HARQ-ACK and the codebook size of the HARQ-ACK need to be sent in the first uplink subframe.

The UE further determines, according to the time information of the periodic CSI feedback of each carrier that is configured, and the activation and deactivation states of each carrier, whether the periodic CSI needs to be sent in the first uplink subframe, and the bits of the periodic CSI information are sent. Number or number. If the UE determines that the UCI that the first uplink subframe needs to transmit includes HARQ-ACK and periodic CSI, the following steps are performed.

Step 903: The UE determines a second uplink channel resource set that is composed of a plurality of pre-configured uplink channel resources.

The access network device is pre-configured with a number of uplink channel resources for the UE. The UE determines a second set of uplink channel resources consisting of a plurality of pre-configured uplink channel resources.

Step 904: The UE determines resource indication information.

When the resource indication information includes only one field, the UE determines the resource indication information according to the information indicated on the predetermined bit in the DCI in the PDCCH corresponding to the downlink data in all the secondary carriers.

When the resource indication information includes two or more fields, the UE receives multiple DCIs that are sent by the access network device by using multiple PDCCH sets corresponding to the downlink data in the secondary carrier, and the UE is from the DCI in each PDCCH set. Each field in the resource indication information is determined, and the resource indication information is finally determined.

Step 905: The UE determines that the channel resource corresponding to the resource indication information in the third uplink channel resource set is the first uplink channel resource, the third uplink channel resource set is a subset of the second uplink channel resource set, and the third uplink channel resource The set matches the codebook size of the HARQ-ACK;

The second uplink channel resource set includes at least two uplink channel resource sets, and the UE first determines that one of the uplink channel resources is a third uplink channel resource set, and the third uplink channel resource set and the HARQ-ACK in the UCI to be sent. The codebook size matches.

Taking the second uplink channel resource set including two uplink channel resource sets: the uplink channel resource set A and the uplink channel resource set B as an example, if the uplink channel resource in the uplink channel resource set A supports the range of the number of bits of the transmitted UCI For [P _A1 , P _A2 ], the range of the number of bits of UCI supported for transmission in the uplink channel resource in the uplink channel resource set B is [P _B1 , P _B2 ], and the codebook size of the HARQ-ACK to be transmitted is Q. If Q is in the range of [P _A1 , P _A2 ], the third uplink channel resource set is the uplink channel resource set A; if Q is in the range of [P _B1 , P _B2 ], the third uplink channel resource set is Upstream channel resource set B. In short, the uplink channel resource in the third uplink channel resource set supports the range of the number of bits of the transmitted UCI or the maximum value of the number of bits and the codebook size of the HARQ-ACK.

or,

A preset matching relationship exists between the codebook size of the HARQ-ACK and each of the uplink channel resource sets in the second uplink channel resource set. For example, if the codebook size of the HARQ-ACK is Q within the first value range, and The matched uplink channel resource set is the first uplink channel resource set in the second uplink channel resource set; when the codebook size of the HARQ-ACK is in the second value range, and the matched uplink channel resource set It is a second uplink channel resource set in the second uplink channel resource set. The first value range and the second value range do not overlap.

Preferably, for each of the at least two uplink channel resource sets included in the second uplink channel resource set, the uplink channel resources in the set have the same resource format, for example, the uplink channel resources in the set are The resources of PUCCH format 3, or the uplink channel resources in the set, are resources of PUCCH format 4. In this way, the UE may determine a PUCCH format corresponding thereto according to the codebook size of the HARQ-ACK information, and then determine a third uplink channel resource set in the second uplink channel resource set according to the determined PUCCH format. For example, the uplink channel resources are both the uplink channel resource set of the PUCCH format 3 and the UCI corresponding to the codebook of the HARQ-ACK information not greater than 22. The uplink channel resources are both the uplink channel resource set of the PUCCH format 4 and the code of the HARQ-ACK information. This UCI corresponds to greater than 22.

Step 906: The UE sends some or all of the information in the UCI on the first uplink channel resource of the first uplink subframe.

After the UE determines the first uplink channel resource, the UE sends the UCI on the first uplink channel resource of the first uplink subframe. If the maximum number of bits of the uplink control information that the first uplink channel resource supports is smaller than the total number of bits of the UCI to be sent, the UE discards part of the periodic CSI information according to the preset priority rule, so that the first uplink channel is used. The UCI information sent in the resource is not greater than the maximum number of bits of the uplink control information that the first uplink channel resource supports, and the maximum number of bits of the uplink control information that is supported by the first uplink channel resource is not less than the total bit of the UCI information to be sent. Number, then all information of the UCI transmitted by the UE in the first uplink channel resource.

Step 907: The access network device determines a codebook size of the HARQ-ACK of the UCI of the UE in the first uplink subframe.

The UCI includes HARQ-ACK and periodic CSI.

The access network device determines, according to the multiple downlink data sent to the UE, and the timing relationship between the multiple downlink data and the corresponding HARQ-ACK, the codebook of the UQ HARQ-ACK of the UE in the first uplink subframe. size.

Step 908: The access network device determines a second uplink channel resource set that is composed of a plurality of uplink channel resources pre-configured to the UE.

This step is similar to step 903.

Step 909: The access network device determines that the channel resource corresponding to the resource indication information in the third uplink channel resource set is the first uplink channel resource, the third uplink channel resource set is a subset of the second uplink channel resource set, and the third The uplink channel resource set matches the codebook size of the HARQ-ACK;

This step is similar to step 905;

Step 910: The access network device receives part or all of the information in the UCI sent by the UE on the first uplink channel resource of the first uplink subframe.

It should be noted that, in this embodiment, the order of execution of steps 907 to 909 is not limited, and all or part of steps 907 to 909 may be performed before step 906.

In summary, in the embodiment of the present invention, the uplink channel resource set having the appropriate maximum number of transmission bits is selected as the third uplink channel resource set by using the codebook size of the HARQ-ACK in the UCI, and then from the third uplink channel. The channel resource corresponding to the resource indication information is determined to be the first uplink channel resource, and the utilization efficiency of the uplink channel resource is improved.

Please refer to FIG. 10, which is a flowchart of a method for transmitting and receiving uplink control information according to still another embodiment of the present invention. This embodiment is exemplified by the method being applied to the communication system shown in FIG. 1. The method includes:

Step 1001: The UE determines a UCI of the second uplink subframe.

The UE may determine, according to the received downlink data, and the timing relationship between the multiple downlink data and the corresponding HARQ-ACK, whether the HARQ-ACK and the codebook size of the HARQ-ACK need to be sent in the second uplink subframe.

The UE further determines, according to the time information of the periodic CSI feedback of each carrier that is configured, and the activation and deactivation states of each carrier, whether the periodic CSI needs to be sent in the second uplink subframe, and the bits of the periodic CSI information are sent. Number or number.

Step 1002: The UE determines a fourth uplink channel resource set that is composed of a plurality of pre-configured uplink channel resources, and the uplink channel resource in the fourth uplink channel resource set supports the same maximum number of UCIs to be sent.

The access network device is pre-configured with a number of uplink channel resources for the UE. In an LTE system, the uplink channel resource refers to a PUCCH resource having a specific PUCCH format and a specific time-frequency location. Optionally, all or part of the pre-configured uplink channel resources further include: attribute information that supports the maximum number of transmitted bits of the UCI, and the maximum coding rate that can be used when transmitting the UCI.

For example, the access network device configures uplink channel resources of PUCCH format 2 for transmitting periodic CSI of each serving cell of the UE by using high layer signaling. For the uplink channel resource of the PUCCH format 2 for transmitting the periodic CSI of each serving cell, the configuration information includes the index number "cqi-PUCCH-ResourceIndex" of the PUCCH resource, and the value range of the index number is selected for the primary carrier. The value ranges from 0 to 1185. For the secondary carrier, the index number ranges from 0 to 1184. Based on the index number and other configuration information of the PUCCH, the time-frequency location corresponding to the PUCCH resource and the sequence resource used may be determined. The maximum number of bits of UCI that can be transmitted on the resources of these PUCCH format 2 is 11. Or, for the PUCCH resource of other formats, the configuration information of the PUCCH resource may further include: a maximum number of bits supporting the UCI, a maximum coding rate that can be used when the UCI is transmitted, and the like.

Step 1003: The UE determines a second uplink channel resource in the fourth uplink channel resource set.

The UE needs to determine a second uplink channel resource in the fourth uplink channel resource set, where the second uplink channel resource is used to send the UCI of the second uplink subframe. If the maximum number of bits of the UCI supported by the uplink channel resource in the fourth uplink channel resource set is the same, the second uplink channel resource is any of the following One:

First, the uplink channel resource with the smallest resource index number in the fourth uplink channel resource set, or

Second, the uplink channel resource with the largest resource index number in the fourth uplink channel resource set, or

Taking the channel resource in the fourth uplink channel resource set as the resource of the PUCCH format 2 as an example. If the UCI of the second uplink subframe includes the periodic CSI information of the at least two serving cells, the second uplink channel resource is the PUCCH resource configured for the at least two serving cells, and the “cqi-PUCCH-ResourceIndex” index number is taken. The uplink channel resource with the smallest value range or the uplink channel resource with the largest value range of the cqi-PUCCH-ResourceIndex index number.

Third, the uplink channel resource with the lowest index of the resource block of the uplink channel resource in the fourth uplink channel resource set, or

Fourth, the resource block of the uplink channel resource in the fourth uplink channel resource set has the largest uplink channel resource index.

Taking the channel resource in the fourth uplink channel resource set as the resource of the PUCCH format 2 as an example. If the UCI information of the second uplink subframe includes the periodic CSI information of the at least two serving cells, the second uplink channel resource is the uplink channel resource with the lowest resource index lower index in each PUCCH resource configured for the at least two serving cells. , or the upstream channel resource with the largest index of the resource block lower index. For example, the resource block index of the PUCCH resource configured for the first serving cell in the at least two serving cells is Q ₁ ～ Q ₂ , where Q ₂ ≥ Q ₁ is the second service of at least two serving cells. The resource block index of the PUCCH resource configured by the cell is Q ₃ ～ Q ₄ , where Q ₄ ≥ Q ₃ , and if Q ₃ > Q ₁ , the uplink channel resource with the smallest resource block index of the uplink channel resource is the first serving cell. The allocated PUCCH resource, the resource block index of the uplink channel resource, and the largest uplink channel resource is the PUCCH resource configured for the second serving cell.

Step 1004: The UE sends the UCI on the second uplink channel resource.

Step 1005: The access network device determines a fourth uplink channel resource set that is composed of a plurality of uplink channel resources that are pre-configured to the UE, and the uplink channel resource in the fourth uplink channel resource set supports the same as the maximum number of transmission bits of the UCI.

This step is similar to step 1002.

Step 1006: The access network device determines a second uplink channel resource in the fourth uplink channel resource set.

This step is similar to step 1003.

Step 1007: The access network device receives the UCI sent by the UE on the second uplink channel resource.

It should be noted that, in this embodiment, the sequence between step 1004 and step 1005 is not limited, and step 1005 may be performed before step 1004. This example does not limit the sequence between step 1004 and step 1006. Step 1006 can be performed prior to step 1004.

In summary, in the embodiment of the present invention, the UE or the access network device determines, by using a pre-configured fourth uplink channel resource set, the second uplink channel resource is the uplink channel used for the current use. The resource does not need to access the network device to send resource indication information to the UE, which saves signaling resources between the UE and the access network device.
