Detailed Description

The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.

wherein each of the communication resources comprises S sets of communication resources; each group of communication resources belonging to the same communication resource comprises the same number of communication resources; each group of the communication resources in different shares of the communication resources comprises different communication resources; wherein S is an integer not less than 2.

The PUCCH resource configuration method described in this embodiment may be applied to a base station or a network element performing resource configuration in any one of the base stations. The communication resources include resources that can be used for wireless communication.

In this embodiment, the maximum number N of communication resources occupied by one PUCCH is first determined. In this embodiment, M communication resources are allocated, where M may be a positive integer less than or equal to N, and is preferably equal to N. S here may be a number of 2, 3, or 4, and the value of S in this embodiment is preferably 4. In this embodiment, the configuration information of the M pieces of communication resources is sent to the terminal, so that the terminal can select the corresponding communication resource to send the physical uplink control feedback information according to the requirement. Here, the

Each part of the communication resources comprises 4 groups of communication resources, the number of the resources included in each group of communication resources in the same part of communication resources is the same, and the number of the communication resources included in each group of communication resources in different parts of communication resources is different, so that the terminal can conveniently select a corresponding part of the communication resources to upload the feedback information of the physical uplink control channel according to the needs of the terminal.

As shown in fig. 2, the step S110 may include:

s111, determining the maximum value N1 of the number of Resource Blocks (RB) of the time-frequency resources occupied by the PUCCH;

the step S120 may include:

step S121: configuring M1 time-frequency resources; the M1 is a positive integer less than or equal to the N1;

wherein, the RB quantity of each group of time frequency resources belonging to the same time frequency resource is the same;

and the number of RBs included in each group of the time frequency resources in different parts of the time frequency resources is different.

In this embodiment, the RB is an abbreviation of Resource Block, and is a Resource unit of a time-frequency Resource.

In this embodiment, the step S110 determines the number N1 of RBs of the time-frequency resource occupied by one PUCCH, and configures M1 time-frequency resources. The value of M1 is a positive integer less than or equal to M1. The number of RBs included in each group of time-frequency resources in different parts of time-frequency resources is different, so that the part of the communication resources can be conveniently determined according to the number of RBs occupied by the data volume required to be sent by the user.

As shown in fig. 3, the step S110 further includes:

step S112: determining a maximum value N2 of the number of orthogonal resources occupied by one PUCCH;

The orthogonal resource described in this embodiment may include a resource in the PUCCH format 3, and a minimum resource unit corresponding to the PUCCH format of code division multiplexing, for example, the orthogonal resource may include an orthogonal sequence used for communication.

The M portions of communication resources may include M1 portions of time-frequency resources and M2 portions of orthogonal resources. The M parts of communication resources may also include only M1 parts of time-frequency resources or M2 parts of orthogonal resources.

The step S130 may include: and sending configuration information to the terminal through high-level signaling.

As a further improvement of this embodiment, the PUCCH formats include X PUCCH formats; wherein X is an integer of not less than 2. For example, the PUCCH format herein may include PUCCH format 3, PUCCH format1b, and the like. The Chinese corresponding to the format is the format. The X PUCCH formats are PUCCH formats configured or required to be used by the communication system in which the base station is located.

The method further comprises the following steps:

Each of the communication resources in this embodiment includes S sets of communication resources, and when it is determined which communication resource is used for transmission of the PUCCH feedback information, which set of communication resource among the communication resources is used for transmission. The transmission power control command is used for indication in this embodiment. And in this embodiment, the transmission power control command can indicate the s-th group of communication resources used by the PUCCH feedback information of at least two PUCCH formats in the X types. It is apparent that S is a positive integer not greater than S.

Two specific indications are provided below in connection with the present embodiment:

the first method is as follows:

the s-th group of communication resources used by the PUCCH feedback information indicating the X PUCCH formats by using the transmission power control command includes:

dividing the secondary cells into X groups;

The cell corresponding to the terminal is divided into a main cell and an auxiliary cell; and typically there may be more than one secondary cell. In this embodiment, the secondary cells are grouped into x groups. And the transmission power control command of each group of the secondary cells indicates the s-th group of communication resources used by the PUCCH feedback information of one PUCCH format.

And a communication resource group used by the PUCCH feedback information of different PUCCH formats indicated by the secondary cells of different groups.

The second method comprises the following steps:

In this embodiment, the secondary cell will indicate the s-th group of communication resources used by the PUCCH feedback information of various PUCCH formats by using respective transmission control commands in turn. In this way, when determining which PUCCH format to use for transmission of PUCCH feedback information, the terminal can use which set of communication resources among the communication resources to perform transmission of the PUCCH feedback information.

Example two:

as shown in fig. 4, an embodiment of the present invention provides a method for sending uplink channel control PUCCH feedback information, where the method includes:

step S210: receiving configuration information including M parts of communication resources from a base station; wherein, the M is determined according to the number N of communication resources occupied by a physical uplink control channel PUCCH; each of said communication resources comprises S sets of communication resources; each group of communication resources belonging to the same communication resource comprises the same number of communication resources; each group of the communication resources in different shares of the communication resources comprises different communication resources; s is an integer not less than 2;

step S220: selecting one communication resource from the M parts of communication resources to be used for sending the physical uplink control channel feedback information according to the information quantity of the physical uplink control channel feedback information to be sent currently and the quantity of the communication resources included in each group of communication resources in each part of communication resources;

step S230: and sending the feedback information of the physical uplink control channel by using the selected communication resource.

In this embodiment, it may be a communication method applied in a terminal, and the configuration information of the M pieces of communication resources is to be received from a base station. And the number of the communication resources is determined according to the number N of the communication resources occupied by one PUCCH.

In step S220, an appropriate communication resource is selected to transmit the uplink channel feedback information according to the information amount of the currently transmitted physical uplink control channel feedback information.

For example, if the physical uplink control channel feedback information needs 2 RBs to be transmitted, the communication resource with each group of communication resources at least including 2 RBs is selected as the communication resource for transmitting the physical uplink control channel feedback information.

The physical uplink control channel feedback information is transmitted using the selected communication resource in step S230. Obviously, this can easily solve the problem that the PUCCH channel in the prior art cannot provide enough communication resources for the terminal to send PUCCH feedback information to the base station.

The M parts of communication resources comprise at least one of the following:

m1 parts of time-frequency resources; the resource blocks RB included in each group of time frequency resources belonging to the same time frequency resource are the same in number; the number of RBs included in each group of the time frequency resources in different parts of the time frequency resources is different;

m2 parts of orthogonal resources; the orthogonal resources included in each group of time frequency resources belonging to the same part of the orthogonal resources have the same number; and the quantity of orthogonal resources included in each group of time frequency resources in different parts of orthogonal resources is different.

The configuration information of the M parts of communication resources may include configuration information of M1 parts of time frequency resources or configuration information of M2 parts of orthogonal resources or configuration information of M1 time frequency resources and configuration information of M2 orthogonal resources.

When the terminal needs to send the PUCCH feedback information, the required communication resources are determined according to the data volume of the PUCCH feedback information to be sent, and then the corresponding communication resources are selected from the configuration information of M1 parts of time-frequency resources, the configuration information of M2 parts of orthogonal resources, the configuration information of M1 parts of time-frequency resources and the configuration information of M2 orthogonal resources to send data.

The step S220 may specifically include:

selecting the mth communication resource of which the number of the communication resources included in each group of communication resources is not less than P as the communication resource for sending the PUCCH feedback information; wherein M is a positive integer not greater than M. For example, if two orthogonal sequences are required for the current terminal to transmit the PUCCH feedback information, the communication resource with each set of orthogonal resources including 2 orthogonal sequences is selected as the communication resource for transmitting the PUCCH feedback information. Thus, step S230 determines which set of communication resources is selected to transmit data according to the selected one of the communication resources and the DCI; obviously, the problem that when the number of carrier aggregation reaches 32, the PUCCH feedback information cannot acquire enough communication resources to be sent is solved skillfully.

In short, by using the PUCCH resource configuration method described in this embodiment, the transmission of PUCCH information in a scenario supporting 32 carrier aggregation can be configured, and communication can be better achieved. It should be noted that the values of M, N, M1, M2, and S in this embodiment are the same as those in the previous embodiment.

Since each of the communication resources includes S sets of communication resources, another method is provided in this embodiment for determining which set of communication resources is used for transmission of the PUCCH feedback information after determining which communication resource is used.

The method further comprises the following steps:

The terminal also receives transmission power control commands from the base station in this embodiment. The transmission power control command herein may correspond to that in the foregoing embodiments. For example, the transmission power control commands of the secondary cells in different groups are received, and the s-th group of communication resources used by the PUCCH feedback information of the corresponding PUCCH format indicated by the transmission power control commands of the secondary cells in each group are determined. For another example, a transmission power control command which is transmitted by each secondary cell in turn and is used for indicating PUCCH feedback information of the PUCCH format is received. Of course, when PUCCH feedback information is transmitted, the PUCCH format to be used by the PUCCH feedback information may be determined according to the information amount of the PUCCH feedback information. Therefore, in this embodiment, it can also be determined which set of communication resources is specifically used according to the PUCCH format and the transmission power control command that need to be used when the PUCCH is fed back.

In summary, in the method described in this embodiment, the communication resources used by the PUCCH feedback information in at least two PUCCH formats may be obtained through the transmission power control command sent by the base station.

Two specific examples are provided below in connection with the above embodiments:

example one:

in a wireless communication system, a dynamic indication of Downlink Control Information (DCI) is retained, but more PUCCH resources can be indicated to a terminal. Here, the PUCCH resource is a communication resource for the PUCCH channel. The base station can configure M1 time-frequency resources for the UE through high-layer signaling, where M1 depends on the number of RBs most occupied by transmitting one PUCCH control channel. Each resource still contains 4 sets of resources, where each resource consists of the same number of RB resources. And the number of RBs per resource is different. For example, the high layer signaling configures 3 resources for the UE, and each of the 4 sets of resources of the first resource includes one RB of 110 RBs; the 4 sets of resources of the second resource each include 2 of the 110 RBs; the 4 sets of resources of the third resource each include 3 of the 110 RBs.

Example two:

the dynamic indication of the DCI is reserved, but M2 resources are configured for the UE through higher layer signaling in order to be able to indicate more PUCCH resources to the terminal, where M2 depends on the number of PUCCH orthogonal resources occupied by transmitting one PUCCH control channel at most. Each orthogonal resource still comprises 4 groups of resources, wherein each resource is composed of the same number of PUCCH orthogonal resources, and the PUCCH orthogonal resources can be the existing PUCCH format 3 resources and can also be the minimum resource unit corresponding to other PUCCH format in a CDM multiplexing mode. The number of the PUCCH orthogonal resources corresponding to each resource is different. For example, the high layer signaling configures 3 resources for the UE, and each of the 4 groups of resources of the first resource indicates one resource of the 550 pucchfmat 3 resources; the 4 sets of resources of the second resource each indicate 2 resources of 550 PUCCH format 3 resources; the 4 sets of resources of the third resource each indicate 3 resources of 550 PUCCH format 3 resources.

Example three:

the dynamic indication of the reserved DCI is not changed, but in order to indicate more resources to the terminal, M1+ M2 communication resources are configured for the UE through higher layer signaling, and M1 depends on the number of RBs occupied by transmitting one PUCCH control channel at most. M2 depends on the number of PUCCH orthogonal resources occupied by transmitting one PUCCH control channel at most. Where each of the M1 resources still contains 4 sets of resources, each resource being composed of the same number of RB resources. And the number of RBs per resource is different. For example, the high layer signaling configures 3 parts of resources for the UE, and each of the 4 groups of resources of the first part of resources indicates one RB of 110 RBs; the 4 sets of resources of the second resource each indicate 2 of the 110 RBs; the 4 sets of resources of the third resource each indicate 3 of the 110 RBs. Each of the M2 orthogonal resources includes 4 sets of resources, where each set of orthogonal resources is composed of the same number of PUCCH orthogonal resources, and the PUCCH orthogonal resources may be existing PUCCH format 3 resources, or may be the smallest resource unit corresponding to the PUCCH format of other CDM multiplexing formats. The number of the PUCCH orthogonal resources corresponding to each resource is different. For example, the high layer signaling configures 3 resources for the UE, and each of the 4 groups of resources of the first resource indicates one of 550 PUCCH format 3 resources; the 4 sets of resources of the second resource each indicate 2 resources of 550 PUCCH format 3 resources; the 4 sets of resources of the third resource each indicate 3 resources of 550 PUCCH format 3 resources.

The base station and the terminal can determine the currently adopted uplink control channel format according to a communication protocol or based on negotiation, further determine the number of resources required to be occupied for feedback, select a certain part of the corresponding number of resources from M1 parts, M2 parts or N + M parts of communication resources, and further select the communication resources for physical uplink control information through a Transmit Power Command (TPC) in DCI.

Example three:

as shown in fig. 5, the present embodiment provides a base station, which includes:

a determining unit 110, configured to determine a maximum value N of the number of communication resources occupied by one PUCCH;

a configuration unit 120, configured to configure M communication resources; wherein M is a positive integer less than or equal to N;

a first sending unit 130, configured to send configuration information of the M pieces of communication resources to a terminal;

wherein each of the communication resources comprises S sets of communication resources; each group of communication resources belonging to the same communication resource comprises the same number of communication resources; each set of the communication resources in different shares of the communication resources comprises different numbers of communication resources.

The base station in the embodiment of the invention can be an evolution type base station eNB and other structures. The specific structures of the determining unit 110 and the configuring unit 120 in this embodiment may correspond to a processor or a processing circuit; the processor may include an application processor, a central processing unit, a microprocessor, a digital signal processor, or a programmable array of such structures. The processing circuitry may comprise an application specific integrated circuit or the like.

The determining unit 110 and the configuring unit 120 may be integrated to correspond to the same processor or processing circuit, or may be integrated to correspond to different processors or processing circuits, and when the determining unit 110 and the configuring unit 120 are integrated to correspond to the same processor or processing circuit, the processors or processing circuits may use time division multiplexing or concurrent threads to perform the functions of the determining unit 110 and the configuring unit 120, respectively.

The first sending unit 130 may correspond to an air interface of the base station, where the air interface may specifically be an antenna or an antenna array. In summary, the first sending unit is capable of sending the configuration information of the M communication resources to the terminal.

In this embodiment, when PUCCH resource configuration is performed, M parts are configured according to the number N of communication resources occupied by one PUCCH channel. Each share of the communication resources is divided into S groups; s here is an integer of not less than 2, and may be 4, for example. The number of the communication resources in each group of communication resources in different parts of communication resources is different, so that the base station can conveniently select one part of communication resources to carry out communication according to the information quantity of PUCCH feedback information to be sent by the base station; obviously, the phenomenon that the PUCCH which the terminal needs to feed back has too much feedback information and does not have communication resources to transmit can be avoided.

Example four:

as shown in fig. 6, the present embodiment provides a terminal, including:

a receiving unit 210, configured to receive configuration information including M parts of communication resources from a base station; wherein, the M is determined according to the number N of communication resources occupied by a physical uplink control channel PUCCH; each of said communication resources comprises S sets of communication resources; each group of communication resources belonging to the same communication resource comprises the same number of communication resources; each group of the communication resources in different shares of the communication resources comprises different communication resources;

a second transmitting unit 230, configured to transmit the PUCCH feedback information by using the selected communication resource.

The receiving unit 210 in this embodiment may correspond to one or more receiving antennas of the terminal.

The selection unit 220 may correspond to a processor or a processing circuit in the terminal. The processor may be an application processor, a central processing unit, a microprocessor, a digital signal processor, or a programmable array. The processing circuitry may comprise an application specific integrated circuit or the like. In short, the selection unit may select one communication resource according to the communication resource required for transmitting the information amount of the PUCCH feedback information to be transmitted.

The second transmitting unit 230 may include one or more transmitting antennas; may be configured to send the PUCCH feedback information to a base station.

The terminal described in this embodiment may be a single-mode mobile phone, a multi-mode mobile phone, an IOS system mobile phone, an android mobile phone, a tablet with a mobile communication function, or a wearable device with a mobile communication function, and in short, hardware for implementing the PUCCH feedback information sending method described in embodiment two may be provided, so that a phenomenon that sufficient communication resources are not sent due to a large amount of information of the PUCCH feedback information is reduced.

As a further improvement of this embodiment, the M parts of communication resources include at least one of:

In this embodiment, the communication resource may include at least one of a time-frequency resource and an orthogonal resource. The M portions of communication resources may include M1 portions of time-frequency resources and/or M2 portions of orthogonal resources. The time frequency resource refers to a time frequency resource or a frequency domain resource. The orthogonal resources may include resources such as orthogonal sequences.

In this embodiment, the content of the communication resource is specifically limited. In this way, the terminal can respectively select one time-frequency resource and one orthogonal resource to transmit the PUCCH feedback information according to the time-frequency resource and the orthogonal resource required for transmitting the PUCCH feedback information to be transmitted.

In addition, the selecting unit 220 is specifically configured to determine the required number P of communication resources according to the data amount of the current PUCCH feedback information to be sent; selecting the mth communication resource of which the number of the communication resources included in each group of communication resources is not less than P as the communication resource for sending the PUCCH feedback information; wherein M is a positive integer not greater than M.

If each set of communication resources under the set of communication resources includes 3 RBs, the set of communication resources may be selected to transmit the PUCCH feedback information. If, in a specific implementation procedure, each of M1 communication resources does not include 3 RBs, but each of M1 communication resources includes 4 RBs, then the communication resource including 4 RBs may be selected for transmitting the PUCCH feedback information.

In this embodiment, the receiving unit 210 is further configured to receive a transmission power control command sent by the base station. The terminal further comprises: a determining unit, configured to determine, according to the transmission power control command, an s-th group of communication resources used by PUCCH feedback information of various PUCCH formats; wherein the S-th set of communication resources is one of S sets of communication resources.

Example five:

in this embodiment, a method for indicating PUCCH resources in a physical uplink control channel is provided, where the PUCCH formats include X PUCCH formats; wherein X is an integer of not less than 2;

the method comprises the following steps:

In the method of the present embodiment, the communication resource used for transmitting PUCCH feedback information of at least 2 PUCCH formats by using the transmission power control command is used. The PUCCH format here may be PUCCH format 3, PUCCH format1b, and the like.

In this embodiment, the transmission power command of the secondary cell may be specifically utilized for indication.

Two specific indications are provided below:

the first method is as follows:

the communication resource used by the PUCCH feedback information indicating the X PUCCH formats by using the transmission power control command includes:

dividing the secondary cells into X groups;

Such a set of secondary cells indicates the communication resources used by the PUCCH feedback information for one PUCCH format.

The second method comprises the following steps:

For example: and grouping the secondary cell Scell, wherein the transmission power control command of the Scell in different groups indicates the communication resources used by the PUCCH feedback information in different PUCCH formats. For example, the number of carriers currently configured to the UE is 10, the first 4 except for the primary cell Pcell are 1 group, the remaining 5 are 2 groups, and the PUCCH field of the transmission power control command of the Scell in the first group indicates the communication resource used by the PUCCH feedback information of the first PUCCH format. As for the PUCCH format based on code division multiplexing CDM, the PUCCH field of the transmission power control command of Scell in the second group indicates a resource of another PUCCH format. Such as PUCCH format of PUSCH-like. After determining the fed-back PUCCH format, the terminal may determine the communication resource used for transmitting the PUCCH feedback information according to the PUCCH field of the transmission power control command in the corresponding group.

For another example: except for the transmission power control command used for indicating the corresponding PUCCH power control on the Pcell, the transmission power control commands H on other Scell indicate communication resources used by PUCCH feedback information of different PUCCH formats in turn.

Fig. 8 is a schematic diagram of a PUCCH resource indication method according to this embodiment. Each row represents a carrier in fig. 8; one carrier corresponds to one cell. The first row corresponds to the primary cell, and the other rows after the first row correspond to the secondary cells. And time corresponding to the horizontal axis, and each small square corresponds to a time-frequency resource.

As shown in fig. 8, except that the TPC command on the Pcell is used for power control, resources of different PUCCH formats are indicated in turn on other scells scheduled for transmission according to a sequence of frequency domain first and time domain later; the PUCCH format indicated first may be a PUCCH format with a smaller corresponding feedback amount. The PUCCH format of the two formats will be indicated with the TPC of the secondary cell in fig. 8. As can be seen from fig. 8, the TPC of the secondary cell sequentially indicates the first PUCCH format and the second PUCCH format in a time domain first and frequency second rotation manner.

Example six:

The transmission power control command can be sent. Of course, in a specific implementation process, the base station further includes a forming unit that forms the transmission power control command. The forming unit may correspond to a processor or a processing circuit. A detailed description of the processor or processing circuitry herein may be found in the corresponding parts of the foregoing embodiments and will not be repeated here.

the grouping module is used for grouping the auxiliary cells into X groups;

In this embodiment, the indication unit is a grouping module that groups the secondary cells; the grouping module may correspond to a processor or a processing circuit and a storage medium. The storage medium may be used to store the grouping results. The indication module may correspond to a transmission interface, and transmit the transmission power control command to the terminal using the transmission interface.

For another example, the indicating unit is further specifically configured to indicate, in turn, communication resources used by PUCCH feedback information of various PUCCH formats by using the transmission power control command of each secondary cell. In this embodiment, the base station uses the indication unit to control the communication resources used by each secondary cell to send PUCCH feedback information in various PUCCH formats in turn.

In summary, the base station according to this embodiment may indicate, by using the transmission control command of the secondary cell, communication resources used by PUCCH feedback information of at least two PUCCH formats.

Of course, the terminal side receives the transmission power control command, analyzes the transmission power control command, and determines communication resources used by PUCCH feedback signals of various PUCCH formats according to the analysis result. When receiving the transmission power control command, determining which PUCCH format the communication resource indicated by the transmission power control command currently corresponds to according to the group or transmission order of the secondary cells sending the transmission power control command. Of course, the base station may also carry the corresponding indication information indicating the PUCCH format in the transmission power control command, so that the terminal can directly analyze the transmission power control command, and know the currently indicated PUCCH format and the communication resource used by the PUCCH feedback information of the PUCCH format.
