Description

Communication device and method thereof

Technical Field

Embodiments of the present invention relate to a communication apparatus and a method thereof, and in particular, to an uplink control information transmitting apparatus, an uplink control information receiving apparatus, and a method thereof via a physical uplink control channel.

Background

In a Machine Type Communication (MTC) Communication system, since a number of terminal devices, such as User Equipment (UE), are numerous, it is an important requirement to reduce the complexity or cost of the terminal.

To meet such a requirement, the bandwidth of a signal that can be supported by a terminal is usually smaller than the maximum system bandwidth of the system (or the maximum channel bandwidth, or the maximum bandwidth configured by the transmission bandwidth configuration) or not larger than a specific system bandwidth (or a specific channel bandwidth, or a specific bandwidth configured by the transmission bandwidth configuration).

Taking Long Term Evolution (LTE) communication system as an example, it specifies 6 system bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20 MHz. The system can determine the required system bandwidth among these 6. For example, when the determined system bandwidth in the LTE system is 20MHz, if a certain terminal only supports a bandwidth of 5 MHz. It is obvious that the bandwidth of the terminal cannot cover the whole system bandwidth of 20 MHz.

The prior art does not consider the situation that the terminal capability is limited. When the limited terminals, i.e. low complexity or low cost terminals, cannot support the bandwidth to cover the whole system bandwidth, the signals of the terminals cannot be compatible with the system bandwidth.

Detailed Description

The invention is mainly applied to an LTE system or an LTE-Advanced (LTE-A) system. The present invention can also be applied to other communication systems in which other entities can receive uplink control information as long as the entity can transmit the uplink control information.

Fig. 1 shows a communication system consisting of a base station and UEs 1-6, in which at least one of the UEs 1-6 may transmit uplink information to the base station, and the base station may receive the uplink information transmitted by at least one of the UEs 1-6. In addition, the UEs 4 to 6 also form a communication system, in which the UE4 or the UE6 may send uplink information to the UE5, the UE5 may receive the uplink information sent by the UE4 or the UE6, and the UE5 may further send the uplink information to the base station.

In a conventional LTE system, the system transmits data through a Physical Resource Block (PRB). The system resources may be divided in frequency into subcarriers. The subcarrier spacing may be 15 KHz.

Fig. 2 shows resources occupied by one uplink subframe, and particularly shows a relationship between a bandwidth supported by a restricted terminal and a system bandwidth. The ordinate is frequency and the abscissa is time. The system resources are divided in time into radio frames (also called system frames). Typically, a radio frame contains 10 subframes, one subframe being 1ms long, each subframe containing two slots. System bandwidth division in frequency

One PRB, n_PRBIs the index of the PRB. One PRB occupies a frequency resource of 180KHz, i.e., the frequency resource of one PRB includes 12 subcarriers. Taking the example that the limited terminal is a low-complexity or low-cost UE, it is assumed that the transmission signal bandwidth that can be supported by the UE is 1.4MHz or N (N is a positive integer, e.g., N ═ 6) PRBs. The corresponding system bandwidth is 20MHz, and obviously, the bandwidth supported by the UE cannot cover the system bandwidth.

The system may partition at least one subband in communication with the terminals. A subband includes one or more frequency resources. For example, a subband may contain one or more PRBs and may also contain one or more subcarriers. The frequency width and the frequency resource location of the frequency resources included in the sub-band may be predetermined or configured by the system according to field conditions. Generally, a frequency width occupied by one sub-band does not exceed a signal bandwidth supported by a terminal. In one subframe, a restricted terminal can receive or transmit signals only in one sub-band. The subbands may also be referred to as narrowband.

The following describes uplink control information.

In the conventional LTE system, the UE transmits uplink control information through a Physical Uplink Control Channel (PUCCH). A conventional PUCCH occupies a frequency width of 1 PRB in frequency, and the 1 PRB may be a PRB on the edge of the system bandwidth. In different slots in the same subframe, the frequency resources mapped by the PUCCH have two different frequency positions. Therefore, when the first slot of the same subframe occupies the PRB at one end of the system bandwidth edge and the other slot occupies the PRB at the other end of the system bandwidth edge, the subframe uses the frequency resources at both ends of the entire system bandwidth.

Fig. 3 is a diagram illustrating physical resource mapping of a conventional PUCCH. When m is different in value, the PUCCH is mapped to different PRBs. m is a parameter obtained from the PUCCH resource index. It can be seen that for the case of m-0, slot 0 and slot 1 are mapped to both ends of the system bandwidth, respectively. For the restricted UE, the supported bandwidth is limited, and the entire system bandwidth cannot be covered, so that the restricted UE cannot transmit uplink control information in the conventional LTE system. In this case, the restricted UE has to adjust the sub-band of the transmission signal between different slots of a subframe to transmit the information carried by the PUCCH, which may cause additional complexity. Considering the adjustment time of the subband in which the signal is transmitted, the UE cannot transmit data within the adjustment time, which may cause a waste of resources within the adjustment time. In addition, if the limited bandwidth of the limited UE is compatible, the system only uses a part of the system bandwidth for data transmission, so that the system bandwidth cannot be fully utilized, and the peak rate of uplink data or the uplink data receiving performance is affected.

In order to solve the above problem, embodiments of the present invention provide an uplink information sending and receiving scheme, so that a base station can reasonably schedule resources for a limited terminal in the entire system bandwidth and fully utilize the system bandwidth.

The radio resource control signaling may be radio resource control common signaling and/or radio resource control proprietary signaling in all embodiments of the present invention. The radio resource control common signaling may be one or more of system information, a system information block, a master information block. The medium access control signaling may be a control element of medium access control. The physical layer signaling may be a control channel carrying control information. The physical uplink control channel is used for carrying uplink control information. The uplink control information may be at least one of Acknowledgement (ACK) information, Negative Acknowledgement (Nack) information, Scheduling Request (SR), Channel State Information (CSI), Channel Quality Indicator (CQI), Rank Indicator (RI), and Precoding Matrix Indicator (PMI). The Physical uplink control channel PUCCH may also be an Enhanced Physical uplink control channel (ePUCCH), a narrowband Physical uplink control channel (Narrow Band PUCCH, NBPUCCH), a Machine Type Physical uplink control channel (Machine Type PUCCH, MPUCCH), or another channel carrying uplink control information.

First embodiment

The present example provides an uplink control information transmitting apparatus, wherein a bandwidth supported by the transmitting apparatus is smaller than a system bandwidth, and the system bandwidth includes a plurality of frequency resources. The frequency resource which can be accommodated by the bandwidth supported by the sending device is a part of the frequency resource in a plurality of frequency resources contained in the system bandwidth. In one subframe, the transmitting device can transmit uplink information only in a part of frequency resources in a system bandwidth, wherein the part of frequency resources comprises a plurality of frequency resources. Typically the transmitting apparatus may be a user terminal, such as User Equipment (UE). The system bandwidth is a frequency bandwidth of all frequency resources supported by the system, and the system bandwidth is divided into a plurality of frequency resources. The frequency resource may be a resource occupied by a Physical Resource Block (PRB) in frequency, or the frequency resource may also be a subcarrier. Although the present embodiment describes the technical solution with uplink control information, those skilled in the art can understand that the solution of the present embodiment can be applied to the transmission of other uplink information based on the same principle and concept.

As shown in fig. 13, the transmission apparatus 100 includes:

a processing unit 102 for determining a first quantity p 1; the first parameter is less than or equal to a first quantity; the first amount is the amount of frequency resources that can be accommodated by the bandwidth supported by the sending device;

the processing unit 102 is configured to determine frequency resource information according to the first parameter;

the processing unit 102 is configured to map a physical uplink control channel to the frequency resource indicated by the frequency resource information;

a sending unit 101, configured to send uplink control information through the physical uplink control channel.

By setting the value of the first parameter p1, determining the corresponding frequency resource mapping, and sending the uplink control information, the sent uplink control information can be limited within the bandwidth supported by the sending device, so that the limited terminal is ensured to transmit the uplink control information, and the limited terminal does not always transmit the uplink control information in the center of the system bandwidth, thereby sufficiently ensuring the peak rate of the uplink data or the receiving performance of the uplink data.

The processing unit, determining the first parameter p1 may be implemented in various ways.

In a first mode, the processing unit is configured to determine a second parameter m according to a physical uplink control channel resource index, where the second parameter is less than or equal to the first quantity; the first parameter is then determined based on the second parameter.

The processing unit is configured to determine a second parameter m according to the physical uplink control channel resource index, and may include: the processing unit is configured to determine a physical uplink control channel resource index according to at least one of the following parameters: a parameter included in Radio Resource Control (RRC) signaling, a parameter included in physical layer signaling, a sequence number of a first Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) carrying downlink control information, a sequence number of a first Enhanced Control Channel Element (ECCE) of an Enhanced Physical Downlink Control Channel (EPDCCH) carrying downlink control information, and a sequence number of a first control channel element of a Physical Downlink Control Channel (PDCCH) of machine type communication carrying downlink control information; and the processing unit is used for determining a second parameter m according to the physical uplink control channel resource index, wherein the second parameter is less than or equal to the first quantity.

Optionally, the PDCCH or EPDCCH may also be another channel for carrying downlink control information, such as a physical downlink control channel for machine type communication carrying downlink control information. The CCE or ECCE may also be an element constituting another channel for carrying downlink control information, such as a control channel element constituting a physical downlink control channel for machine type communication.

For example, one way for the processing unit to determine the second parameter m according to the physical uplink control channel resource index is as follows:

wherein the content of the first and second substances,

is the physical uplink control channel resource index. Alternatively to this, the first and second parts may,

is a parameter configured by Radio Resource Control (RRC) signaling, or is a parameter calculated by the parameter configured by RRC signaling and a sequence number of a first (lowest) control channel element constituting a physical downlink control channel. The physical downlink control channel may be a PDCCHOr EPDCCH, or other channel for carrying downlink control information. The control channel element may be a CCE, or an ECCE, or an element constituting another channel for carrying downlink control information. The Downlink control information includes resource scheduling information of a Physical Downlink Shared Channel (PDSCH), and the Physical uplink control channel carries acknowledgement or negative acknowledgement information of the PDSCH.

Indicating the number of available PRBs per time slot for transmission of the physical uplink control channel format 2/2a/2 b.

Indicates the number of cyclic shifts used for the physical uplink control channel format 1/1a/1b in PRBs used for hybrid mapping of the physical uplink control channel format 1/1a/1b and the format 2/2a/2 b.

Is a parameter of RRC signaling configuration.

Is the number of subcarriers included in the frequency domain by the PRB.

In order to make the second parameter less than or equal to the first quantity, the maximum value of the physical uplink control channel resource index needs to be less than a certain value, for example, the maximum value is less than 2047.

The processing unit is configured to determine the first parameter according to the second parameter by using the following formula:

alternatively, p1 ═ m ═ 2)

Or

Or

Or

Or

Wherein N is_NBM is the second parameter, p1 is the first parameter, n is the first quantity_sIs the time slot number, n_sfIs the subframe number.

Denotes rounding down, X is the sum n_s、n_sfAt least one related parameter among the number of the wireless frame, the number of the uplink subframe included between the starting subframe for transmitting the uplink control information and the current subframe. For example X is n_sf. And for example X is 10X SFN + n_sfSFN is the radio frame number. For another example, X is the number of subframes included between the starting subframe for transmitting the uplink control information and the current subframe or the number of uplink subframes. Y is a predefined parameter, or Y is a parameter related to the physical uplink control channel frequency hopping granularity, or Y is a parameter related to the physical uplink control channel frequency hopping period. The frequency resource mapped by the physical uplink control channel may change, which is called physical uplink control channel frequency hopping. The frequency resource mapped by the physical uplink control channel changes once every G subframes, which is called as physical uplink control channel frequency hopping granularity. The change rule of the frequency resource mapped by the physical uplink control channel is repeated once every H subframes, and then the H subframes are called as a frequency hopping period of the physical uplink control channel. For example, Y is the physical uplink control channel hopping granularity. The physical uplink control channel hopping may occur in a plurality of subframes in which the physical uplink control channel is mapped or the transmitting unit transmits the uplink control information. I.e. a plurality of sub-frames before and after the frequency resource mapped by the physical uplink control channel changes, the transmitting unit transmits the phaseThe same uplink control information. X and Y determine the time of frequency hopping of the physical uplink control channel.

For example, referring to formula (1), when the transmission bandwidth supported by the UE can only accommodate 6 PRBs in frequency, the number of frequency resources that can be accommodated by the transmission bandwidth supported by the UE is 6, N _NB6. The base station enables the value range of the calculated m value to be 0-5 by selecting at least one of the value of RRC signaling configuration, the CCE forming the PDCCH and the ECCE forming the EPDCCH, so that the base station can obtain the M value with the maximum transmission rate

The value range of (A) is 0 to 2,

the value range of (2) is 3-5, and the value of the first parameter determined by the UE is not more than 6.

Fig. 4 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (1). Wherein the shaded portion is the physical resource of the physical uplink control channel when m is 0.

Fig. 5 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (2). Wherein the shaded portion is the physical resource of the physical uplink control channel when m is 0. Fig. 5 and equation (2) show that the first parameter p1 is determined according to the physical uplink control channel resource index.

Fig. 6 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (3). Wherein the shaded portion is the physical resource of the physical uplink control channel when m is 0.

Fig. 23 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (4). The shaded part is the physical resource of the physical uplink control channel when m is 0 and the physical resource of the physical uplink control channel when m is 1.

Fig. 24 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (5). The shaded part is the physical resource of the physical uplink control channel when m is 0 and the physical resource of the physical uplink control channel when m is 1.

Fig. 25 exemplarily shows a relationship of a frequency resource and a time slot obtained according to equation (6). The shaded part is the physical resource of the physical uplink control channel when m is 0 and the physical resource of the physical uplink control channel when m is 1.

As can be seen from fig. 4-6 and fig. 23-25, the physical resources corresponding to m ═ 0 or m ═ 1 are within the sub-band range, and scheduling within the entire system bandwidth can be implemented according to the difference of m ×, and the difference of sub-bands.

The processing unit, determining the first parameter p1 may be implemented in a second manner of a plurality of manners, and the processing unit, configured to determine the first parameter p1, includes:

wherein

Wherein the content of the first and second substances,

is the number of frequency resources, N, contained in the system bandwidth_NBM is a parameter determined according to a physical uplink control channel resource index, p1 is the first parameter, n is the first quantity_sIs the time slot number, n_PRBIs an intermediate variable. The physical uplink control channel resource index may be an existing PUCCH index. The determination method of m is the same as that of the existing PUCCH. For example, when the system bandwidth may contain 100 PRBs in frequency,

n_PRBthe value range is 0-99. When the transmission bandwidth supported by the UE can only accommodate 6 PRBs in frequency, the number of frequency resources that can be accommodated by the transmission bandwidth supported by the UE is 6, N_NB＝6。

The value range of p1 is 0-5 and not more than 6.

The processing unit, determining the first parameter p1 may be implemented in a third manner of a plurality of manners, and the processing unit, configured to determine the first parameter p1, includes: the processing unit is configured to determine the first parameter p1 according to the physical uplink control channel resource index.

Specifically, the processing unit is configured to determine a physical uplink control channel resource index according to at least one of the following parameters: parameters contained in Radio Resource Control (RRC) signaling, parameters contained in physical layer signaling, a sequence number of a first Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) bearing downlink control information, a sequence number of a first Enhanced Control Channel Element (ECCE) of an Enhanced Physical Downlink Control Channel (EPDCCH) bearing downlink control information, and a sequence number of a first control channel element of a physical downlink control channel of machine type communication bearing downlink control information; the processing unit is configured to determine a first parameter p1 according to the physical uplink control channel resource index.

For example, one way for the processing unit to determine the first parameter p1 according to the physical uplink control channel resource index is as follows:

wherein the content of the first and second substances,

is the physical uplink control channel resource index.

And other parameters are specifically described in the first way of determining the first parameter p1 by the processing unit, and are not described herein again.

In order to make the first parameter less than or equal to the first quantity, the maximum value of the physical uplink control channel resource index needs to be less than a certain value, for example, the maximum value is less than 2047.

The manner of determining the first parameter p1 can limit the transmitted uplink control information within the bandwidth supported by the transmitting apparatus, thereby ensuring that the limited device transmits the uplink control information, and fully utilizing the peak rate of the uplink data or ensuring the receiving performance of the uplink data.

To more specifically illustrate the manner in which frequency resource information is determined, the concept of subbands may be introduced. However, the present invention is not limited to the necessity of using subbands to determine frequency resource information. It will be appreciated that in some specific ways, instead of using the concept of sub-bands, the range of frequency resources used may also be limited to a certain range to produce the same technical effect.

The system bandwidth may include one or more sub-bands, the sub-bands having bandwidths less than or equal to bandwidths supported by the transmitting device, the sub-bands including at least one frequency resource,

the processing unit, configured to determine frequency resource information according to the first parameter, may include:

For example, if the sub-band index of the first sub-band is even and the sub-band index of the second sub-band is the smallest odd number greater than the sub-band index of the first sub-band, the processing unit determines the sub-band index of the first sub-band by receiving the system information block, and determines that the sub-band index of the second sub-band is the sub-band index of the first sub-band plus 1 according to the sub-band index of the first sub-band. After determining the subband index of the first subband and the subband index of the second subband, the processing unit may determine the first subband and the second subband indicated by the subband index according to the subband index, a predefined subband and a subband number.

For another example, when the first information of the first sub-band is a minimum wideband frequency resource index of frequency resources included in the first sub-band and the first information of the second sub-band is a minimum wideband frequency resource index of frequency resources included in the second sub-band, the processing unit determines the second sub-band by receiving a system information blockThe minimum broadband frequency resource index of the frequency resources contained in one sub-band is f_{NB1_min}Then, the minimum wideband frequency resource index of the frequency resource contained in the second sub-band can be determined as

From the frequency resource location contained in the first subband, the frequency resource location symmetrical to the frequency resource location contained in the first subband about the center of the system bandwidth, i.e. the second subband is determined.

Thirteenth embodiment

The present example provides a terminal. Although the present embodiment describes the technical solution with uplink control information, those skilled in the art can understand that the solution of the present embodiment can be applied to the transmission of other uplink information based on the same principle and concept.

As shown in fig. 30, the terminal 1300 includes:

a processing unit 1301, configured to determine at least two sub-bands, where each sub-band includes at least one frequency resource, and a bandwidth of each sub-band is less than or equal to a bandwidth supported by the terminal;

the processing unit 1301 is further configured to determine third frequency resource information according to a sub-band region physical uplink control channel resource index, where the third frequency resource information indicates a third frequency resource in frequency resources included in the at least two sub-bands, and the sub-band region physical uplink control channel resource index indicates a physical uplink control channel resource in the at least two sub-bands;

the processing unit 1301 is further configured to map a physical uplink control channel to the third frequency resource;

a transceiving unit 1302, configured to send the uplink control information through the physical uplink control channel.

By determining at least two sub-bands, further determining corresponding frequency resource mapping, and sending uplink control information, the sent uplink control information can be limited within the sub-bands, i.e., within the bandwidth supported by the sending device, thereby ensuring that the limited terminal transmits the uplink control information, being beneficial to avoiding the uplink control information from dividing the frequency resources within the uplink system bandwidth into several parts, and further ensuring the peak rate of uplink data and the receiving performance of the uplink data.

Optionally, the processing unit may determine at least two sub-bands and may determine an even number of sub-bands, such as: 2 subbands, 4 subbands, 6 subbands. To identify the different subbands, a subband index may be used. A sub-band may also have a minimum wideband frequency resource index of the frequency resources contained by the sub-band, a maximum wideband frequency resource index of the frequency resources contained by the sub-band, and a center frequency resource index of the frequency resources contained by the sub-band. Therefore, the processing unit may determine first information of the at least two sub-bands, the first information of the sub-bands including at least one of: a subband index, a minimum wideband frequency resource index of the frequency resources contained in the subband, a maximum wideband frequency resource index of the frequency resources contained in the subband, and a center frequency resource index of the frequency resources contained in the subband. Through the first information of the sub-band, the relevant characteristics of the sub-band can be known, i.e. the sub-band is determined. Such as the width of the sub-band, all frequency resources of the sub-band.

Optionally, when there are two or more terminals, the terminal is divided into a plurality of terminal pairs, and each terminal pair includes a first terminal and a second terminal. And the third frequency resource indicated by the third frequency resource information determined by the first terminal and the third frequency resource indicated by the third frequency resource information determined by the second terminal are symmetrical relative to the center frequency of the system bandwidth. Therefore, when the terminal with limited transmission bandwidth transmits the uplink control information, the uplink control information divides the frequency resource in the uplink system bandwidth into a plurality of parts, thereby ensuring that the uplink data occupies continuous frequency resources and achieving the peak rate of the uplink data.

It can be understood that when even number of subbands contain frequency resources that are symmetric with respect to the center frequency of the system bandwidth, it is easier to make the frequency resources occupied by these even number of terminals symmetric with respect to the center frequency of the system bandwidth when the even number of terminals belong to symmetric subbands. In other words, the at least two sub-bands include a first sub-band and a second sub-band, the frequency resources included in the first sub-band and the frequency resources included in the second sub-band are symmetric with respect to a center frequency of the system bandwidth, wherein the third frequency resource information of the first terminal indicates a third frequency resource in the frequency resources included in the first sub-band, and the third frequency resource information of the second terminal indicates a third frequency resource in the frequency resources included in the second sub-band.

The present embodiment also includes the case where the sub-band is asymmetric, and the same effect can be achieved as long as the frequency resources occupied by the even number of terminals are symmetric with respect to the center frequency of the system bandwidth.

How the sub-bands are determined is explained below. The processing unit determines at least two sub-bands, and a system information block SIB can be received by the transceiver unit; and a processing unit configured to determine first information of the first subband by the system information block SIB; and then determining the second sub-band according to the first information of the first sub-band. Or, in the case that the first sub-band is known, the characteristic of the second sub-band can be known according to the symmetrical characteristic of the first sub-band and the second sub-band with respect to the center frequency of the system bandwidth.

For example, when the first information of the first subband is a subband index of the first subband and the first information of the second subband is a subband index of the second subband, and the subband index of the first subband and the subband index of the second subband are continuous natural numbers, the processing unit may determine the subband index of the first subband by receiving the system information block, and may determine that the subband index of the second subband is the subband index of the first subband plus 1 or minus 1 according to the subband index of the first subband. For example, if the sub-band index of the first sub-band is even and the sub-band index of the second sub-band is the smallest odd number greater than the sub-band index of the first sub-band, the processing unit determines the sub-band index of the first sub-band by receiving the system information block, and determines that the sub-band index of the second sub-band is the sub-band index of the first sub-band plus 1 according to the sub-band index of the first sub-band. The processing unit may determine the second subband based on a subband index of the second subband.

Wherein the content of the first and second substances,

is the number of frequency resources, N, contained in the system bandwidth_NBIs the first number. The processing unit may determine the second sub-band according to a minimum wideband frequency resource index of the frequency resources included in the second sub-band and the number of frequency resources included in the second sub-band.

For another example, when the first information of the first subband is a subband index of the first subband, the processing unit may determine the subband index of the first subband by receiving a system information block, and determine the first subband indicated by the subband index according to the subband index, a predefined subband and a predefined subband number. From the frequency resource location contained in the first subband, the frequency resource location symmetrical to the frequency resource location contained in the first subband about the center of the system bandwidth, i.e. the second subband is determined. Such as one of the frequencies comprised by said first sub-bandA wideband frequency resource index of the rate resource is f_NB1Then the wideband frequency resource index of the frequency resource which is symmetric about the center of the system bandwidth is

Wherein the content of the first and second substances,

is the amount of frequency resources contained in the system bandwidth.

By the above manner, the processing unit determines the second sub-band according to the first information of the first sub-band, so that signaling overhead of the base station for configuring the first information of the first sub-band and the second sub-band is saved.

The sub-band region physical uplink control channel resource index indicates physical uplink control channel resources in the at least two sub-bands. And numbering the physical uplink control channel resources in the at least two sub-bands, namely, the sub-band region physical uplink control channel resource index. On one frequency resource of one subframe, there may be a plurality of physical uplink control channel resources, which are code division multiplexed. The number is a joint number of the physical uplink control channel resources in the at least two subbands.

How to determine the sub-band region physical uplink control channel resource index is described below, the sub-band region physical uplink control channel resource index may be determined according to at least one of the following parameters: parameters contained in Radio Resource Control (RRC) signaling, parameters contained in physical layer signaling, a sequence number of a first Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) bearing downlink control information, a sequence number of a first Enhanced Control Channel Element (ECCE) of an Enhanced Physical Downlink Control Channel (EPDCCH) bearing downlink control information, and a sequence number of a first control channel element of a physical downlink control channel of machine type communication bearing downlink control information. Optionally, the determining method of the subband region physical uplink control channel resource index is the same as the determining method of the existing PUCCH resource index. Different from the existing PUCCH resource index, to ensure that the subband area physical uplink control channel resource index is the number of the physical uplink control channel resource in the at least two subbands, the value ranges of one or more of the parameters included in the RRC signaling, the parameters included in the physical layer signaling, and the sequence number of the first control channel element are different from the value ranges of the above parameters determining the existing PUCCH resource index.

In this embodiment, the frequency resources included in the at least two sub-bands form an integrated frequency resource set. To indicate these frequency resources, a third frequency resource index n may be used_{PRB_NB_MUL_s1}. The third frequency resource index may be a number of frequency resources included in the at least two sub-bands. The value range is 0 to the number of frequency resources-1 contained in the at least two sub-bands. For example, the range of values may be

The third frequency resource index may also be numbered from 1, and the physical resource mapping methods of the corresponding physical uplink control channels all belong to the protection scope of the embodiment of the present invention. The processing unit may determine third frequency resource information according to a subband region physical uplink control channel resource index, including:

the processing unit is configured to determine a third parameter m 'according to a resource index of a physical uplink control channel in a subband region, where m' is less than or equal to the number of frequency resources included in the at least two subbands; determining the index n of the third frequency resource according to m_{PRB_NB_MUL_s1}。

wherein the content of the first and second substances,

is the physical uplink control channel resource index of the sub-band region. The other parameters are specifically described in the first manner of determining the first parameter p1 by the processing unit in the first embodiment, and are not described herein again.

Wherein the processing unit determines the third frequency resource index n according to m_{PRB_NB_MUL_s1}The method comprises the following steps:

the third frequency resource index n_{PRB_NB_MUL_s1}The relationship with m' satisfies the following formula:

alternatively, the first and second electrodes may be,

meaning that the rounding is done down,

x comprises one or more or a combination of more of the following parameters:

time slot number n_sSubframe number n_sfThe wireless frame number, the number of uplink subframes included between the initial subframe for sending the uplink control information and the current subframe;

y comprises one or more or a combination of more of the following parameters:

predefined parameters, the frequency hopping granularity of the physical uplink control channel and the frequency hopping period of the physical uplink control channel.

For example X is n_sf. And for example X is 10X SFN + n_sfSFN is the radio frame number. For another example, X is the number of subframes included between the starting subframe for transmitting the uplink control information and the current subframe or the number of uplink subframes. The frequency resource mapped by the physical uplink control channel may change, which is called physical uplink control channel frequency hopping. The frequency resource mapped by the physical uplink control channel changes once every G subframes, which is called as physical uplink control channel frequency hopping granularity. The change rule of the frequency resource mapped by the physical uplink control channel is repeated once every H subframes, and then the H subframes are called as a frequency hopping period of the physical uplink control channel. For example, Y is the physical uplink control channel hopping granularity. The physical uplink control channel hopping may occur in a plurality of subframes in which the physical uplink control channel is mapped or the transmitting unit transmits the uplink control information. That is, the transmitting unit transmits the same uplink control information in a plurality of subframes before and after a change in frequency resources mapped to the physical uplink control channel. X and Y determine the time of frequency hopping of the physical uplink control channel.

FIG. 26 shows a third frequency resource index n including a first sub-band and a second sub-band_{PRB_NB_MUL_s1}The relationship with m'.

Alternatively, as shown in fig. 27, the third frequency resource occupied by the same terminal may be changed, for example, m ═ 0 is hopped from the first subband to the second subband. Assuming that the determined third frequency resource information is a third frequency resource index n before the third frequency resource information changes_{PRB_NB_MUL_s1_pre}，

When the third frequency resource information changes, determining a third frequency resource index n after the third frequency resource information changes according to the third frequency resource information change rule_{PRB_NB_MUL_s1_after}(ii) a Wherein the third frequency resource information change rule is:

The number of frequency resources contained in the at least two sub-bands.

It is to be understood that the above third frequency resource index is a number of frequency resources included in the at least two sub-bands, and is a relative index.

In order to identify the frequency resources contained in the at least two sub-bands, a wideband frequency resource index may also be used, where the wideband frequency resource index is an index of a frequency resource contained in a system bandwidth, and the system bandwidth is a bandwidth supported by an access network device communicating with the terminal. In other words, the entire bandwidth supported by the access network device is divided into different frequency resources, and all of these frequency resources are indexed with a wideband frequency resource index. This is an absolute index. The value range of the wideband frequency resource index can be 0 to the number of frequency resources contained in the system bandwidth-1. For example, the range of values may be

Assuming that the determined third frequency resource information is a wideband frequency resource index n before the third frequency resource information changes_{PRB_pre}When the third frequency resource information changes, determining the broadband frequency resource index n after the third frequency resource information changes according to the third frequency resource information change rule_{PRB_after}(ii) a Wherein the third frequency resource information change rule is:

wherein

Is the amount of frequency resources contained in the system bandwidth. Optionally, the processing unit is configured to determine, according to a predetermined rule, a time interval at which the third frequency resource information changes or a subframe at which the frequency resource information changes in the plurality of subframes;

optionally, the processing unit is configured to determine a time interval when the third frequency resource information changes or a subframe when the frequency resource information changes by receiving at least one of a radio resource control signaling, a medium access control signaling, and a physical layer signaling;

optionally, the processing unit is configured to determine that a time interval at which the third frequency resource information changes is a divisor of the number of the subframes of the plurality of subframes. The following introduces mapping of physical uplink control channels to the third frequency resources. Since the terminal requires a preparation time at the time of frequency hopping, a sufficient guard time is required to complete the frequency hopping preparation. It is understood that the guard time may be one slot or a plurality of slots, or may be one subframe or a plurality of subframes. Fig. 27 shows a two slot scheme. Besides, the following scheme can be included:

if the third frequency resource indicated by the third frequency resource information determined by the processing unit is different in two adjacent subframes, the processing unit maps the physical uplink control channel to the third frequency resource in the first time slot of the previous subframe of the two subframes, and does not map the physical uplink control channel in the other time slot of the previous subframe; or

The processing unit maps the physical uplink control channel to the third frequency resource in the second time slot of the next subframe of the two subframes, and does not map the physical uplink control channel in the other time slot of the next subframe; or

The processing unit maps the physical uplink control channel to the third frequency resource in the former subframe of the two subframes, and does not map the physical uplink control channel in the latter subframe of the two subframes; or

And the processing unit maps the physical uplink control channel to the third frequency resource in the next subframe of the two subframes, and does not map the physical uplink control channel in the previous subframe of the two subframes.

It can be understood that the frequency resource in this embodiment may be a resource occupied by one physical resource block PRB on a frequency band, or may be other frequency resources with a bandwidth; or the frequency resource is a subcarrier in an LTE system or a similar concept.

The terminal of the embodiment of the invention maps the physical uplink control channel into one sub-band of one sub-frame, so that the frequency width mapped by one sub-frame does not exceed the bandwidth of a sending signal supported by the terminal with low complexity or low cost, and the terminal can be ensured to send the uplink control information. By the determination or change mode of the third frequency resource information in this embodiment, it can be ensured that the frequency resources mapped before and after the frequency hopping of the physical uplink control channel are symmetric with respect to the center of the system bandwidth, thereby reducing the fragmentation of the uplink control information transmission on the uplink data transmission frequency resources, and ensuring the peak rate of the uplink data or the uplink data reception performance.

Fourteenth embodiment

The present example provides a communication method. Although the present embodiment describes the technical solution with uplink control information, those skilled in the art can understand that the solution of the present embodiment can be applied to the transmission of other uplink information based on the same principle and concept. For a specific implementation process, reference may be made to a method implemented by an embodiment of the apparatus in the thirteenth embodiment.

As shown in fig. 31, the method includes:

step 1401, determining at least two sub-bands, wherein the sub-bands comprise at least one frequency resource, and the bandwidth of each sub-band is less than or equal to the bandwidth supported by the terminal;

step 1402, determining third frequency resource information according to a sub-band region physical uplink control channel resource index, where the third frequency resource information indicates a third frequency resource in frequency resources included in the at least two sub-bands, and the sub-band region physical uplink control channel resource index indicates a physical uplink control channel resource in the at least two sub-bands;

step 1403, mapping the physical uplink control channel to the third frequency resource;

step 1404, sending the uplink control information through the physical uplink control channel.

Alternatively, it may be determined that at least two subbands may determine an even number of subbands, such as: 2 subbands, 4 subbands, 6 subbands. To identify the different subbands, a subband index may be used. A sub-band may also have a minimum wideband frequency resource index of the frequency resources contained by the sub-band, a maximum wideband frequency resource index of the frequency resources contained by the sub-band, and a center frequency resource index of the frequency resources contained by the sub-band. Therefore, first information of the at least two sub-bands is determined, the first information of the sub-bands comprises at least one of the following: a subband index, a minimum wideband frequency resource index of frequency resources contained in the subband, a maximum wideband frequency resource index of frequency resources contained in the subband, and a center frequency resource index of frequency resources contained in the subband. Optionally, when there are two or more terminals, the terminal is divided into a plurality of terminal pairs, and each terminal pair includes a first terminal and a second terminal. And the third frequency resource indicated by the third frequency resource information determined by the first terminal and the third frequency resource indicated by the third frequency resource information determined by the second terminal are symmetrical relative to the center frequency of the system bandwidth. Therefore, when the terminal with limited transmission bandwidth transmits the uplink control information, the uplink control information divides the frequency resource in the uplink system bandwidth into a plurality of parts, thereby ensuring that the uplink data occupies continuous frequency resources and achieving the peak rate of the uplink data. It can be understood that when even number of subbands contain frequency resources that are symmetric with respect to the center frequency of the system bandwidth, it is easier to make the frequency resources occupied by these even number of terminals symmetric with respect to the center frequency of the system bandwidth when the even number of terminals belong to symmetric subbands. In other words, the at least two sub-bands include a first sub-band and a second sub-band, the frequency resources included in the first sub-band and the frequency resources included in the second sub-band are symmetric with respect to a center frequency of the system bandwidth, wherein the third frequency resource information of the first terminal indicates a third frequency resource in the frequency resources included in the first sub-band, and the third frequency resource information of the second terminal indicates a third frequency resource in the frequency resources included in the second sub-band.

How the sub-bands are determined is explained below. A system information block, SIB, may be received; determining first information of the first sub-band through the system information block SIB; and then determining the second sub-band according to the first information of the first sub-band. Or, in the case that the first sub-band is known, the characteristic of the second sub-band can be known according to the symmetrical characteristic of the first sub-band and the second sub-band with respect to the center frequency of the system bandwidth. For example, when the first information of the first sub-band is a sub-band index of the first sub-band and the first information of the second sub-band is a sub-band index of the second sub-band, and the sub-band index of the first sub-band and the sub-band index of the second sub-band are consecutive natural numbers, the sub-band index of the first sub-band is determined by the receiving system information block, and the sub-band index of the second sub-band can be determined to be the sub-band index of the first sub-band plus or minus 1 according to the sub-band index of the first sub-band. For example, if the sub-band index of the first sub-band is even and the sub-band index of the second sub-band is the smallest odd number greater than the sub-band index of the first sub-band, the sub-band index of the first sub-band is determined by receiving the system information block, and the sub-band index of the second sub-band is determined by adding 1 to the sub-band index of the first sub-band according to the sub-band index of the first sub-band. The second subband may be determined based on the subband index of the second subband.

Also for example, when the first information of the first sub-band is the first sub-bandWhen the minimum wideband frequency resource index of the frequency resources contained in the band is the minimum wideband frequency resource index of the frequency resources contained in the second sub-band, the minimum wideband frequency resource index of the frequency resources contained in the first sub-band is determined to be f by receiving the system information block_{NB1_min}Then, the minimum wideband frequency resource index of the frequency resource contained in the second sub-band can be determined as

Wherein the content of the first and second substances,

is the number of frequency resources, N, contained in the system bandwidth_NBIs the first number. And determining the second sub-band according to the minimum wideband frequency resource index of the frequency resources contained in the second sub-band and the number of the frequency resources contained in the second sub-band.

By the method, the second sub-band is determined according to the first information of the first sub-band, so that the signaling overhead of the base station for configuring the first information of the first sub-band and the second sub-band is saved.

How to determine the sub-band region physical uplink control channel resource index is described below, the sub-band region physical uplink control channel resource index may be determined according to at least one of the following parameters: parameters contained in Radio Resource Control (RRC) signaling, parameters contained in physical layer signaling, a sequence number of a first Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) bearing downlink control information, a sequence number of a first Enhanced Control Channel Element (ECCE) of an Enhanced Physical Downlink Control Channel (EPDCCH) bearing downlink control information, and a sequence number of a first control channel element of a physical downlink control channel of machine type communication bearing downlink control information.

In this embodiment, the frequency resources included in the at least two sub-bands form an integrated frequency resource set. To indicate these frequency resources, a third frequency resource index n may be used_{PRB_NB_MUL_s1}. The third frequency resource index may be a number of frequency resources included in the at least two sub-bands. The value range is 0 to the number of frequency resources-1 contained in the at least two sub-bands.

The third frequency resource information may be determined according to the sub-band region physical uplink control channel resource index, including:

determining a third parameter m 'according to the resource index of the physical uplink control channel in the sub-band region, wherein m' is less than or equal to the number of frequency resources contained in the at least two sub-bands; determining the index n of the third frequency resource according to m_{PRB_NB_MUL_s1}。

Wherein the third frequency resource index n is determined according to m_{PRB_NB_MUL_s1}The method comprises the following steps:

alternatively, the first and second electrodes may be,

wherein

Is the number of frequency resources comprised by the at least two sub-bands,

meaning that the rounding is done down,

x comprises one or more or a combination of more of the following parameters:

y comprises one or more or a combination of more of the following parameters:

For example X is n_sf. And for example X is 10X SFN + n_sfSFN is the radio frame number. For another example, X is the number of subframes included between the starting subframe for transmitting the uplink control information and the current subframe or the number of uplink subframes. The frequency resource mapped by the physical uplink control channel may change, which is called physical uplink control channel frequency hopping. The frequency resource mapped by the physical uplink control channel changes once every G subframes, which is called as physical uplink control channel frequency hopping granularity. The change rule of the frequency resource mapped by the physical uplink control channel is repeated once every H subframes, and then the H subframes are called as a frequency hopping period of the physical uplink control channel. For example, Y is the physical uplink control channel hopping granularity. The physical uplink control channel hopping may occur in a plurality of subframes in which the physical uplink control channel is mapped or uplink control information is transmitted. That is, the same uplink control information is transmitted in a plurality of subframes before and after the frequency resource mapped by the physical uplink control channel changes. X and Y determine the time of frequency hopping of the physical uplink control channel.

Alternatively, as shown in fig. 27, the third frequency resource occupied by the same terminal may be changed, for example, m ═ 0 is hopped from the first subband to the second subband. Assuming that the determined third frequency resource information is the third frequency resource information before the third frequency resource information changesN is led_{PRB_NB_MUL_s1_pre}，

wherein

The number of frequency resources contained in the at least two sub-bands.

In order to identify the frequency resources contained in the at least two sub-bands, a wideband frequency resource index may also be used, where the wideband frequency resource index is an index of a frequency resource contained in a system bandwidth, and the system bandwidth is a bandwidth supported by an access network device communicating with the terminal. In other words, the entire bandwidth supported by the access network device is divided into different frequency resources, and all of these frequency resources are indexed with a wideband frequency resource index. This is an absolute index. The value range of the wideband frequency resource index can be 0 to the number of frequency resources contained in the system bandwidth-1.

wherein

Is the amount of frequency resources contained in the system bandwidth.

The following introduces mapping of physical uplink control channels to the third frequency resources. Since the terminal requires a preparation time at the time of frequency hopping, a sufficient guard time is required to complete the frequency hopping preparation. It is understood that the guard time may be one slot or a plurality of slots, or may be one subframe or a plurality of subframes. Fig. 27 shows a two slot scheme. Besides, the following scheme can be included:

if the third frequency resource indicated by the determined third frequency resource information is different in two adjacent subframes, mapping the physical uplink control channel to the third frequency resource in the first time slot of the previous subframe in the two subframes, and not mapping the physical uplink control channel in the other time slot of the previous subframe; or

Mapping the physical uplink control channel to the third frequency resource in the second time slot of the next subframe of the two subframes, and not mapping the physical uplink control channel in the other time slot of the next subframe; or

Mapping the physical uplink control channel to the third frequency resource in the former subframe of the two subframes, and not mapping the physical uplink control channel in the latter subframe of the two subframes; or

And mapping the physical uplink control channel to the third frequency resource in the next subframe of the two subframes, and not mapping the physical uplink control channel in the previous subframe of the two subframes.

The communication method of the embodiment of the invention maps the physical uplink control channel into one sub-band of one sub-frame, so that the frequency width mapped by one sub-frame does not exceed the bandwidth of a sending signal supported by a terminal with low complexity or low cost, and the terminal can be ensured to send uplink control information. By the determination or change mode of the third frequency resource information in this embodiment, it can be ensured that the frequency resources mapped before and after the frequency hopping of the physical uplink control channel are symmetric with respect to the center of the system bandwidth, thereby reducing the fragmentation of the uplink control information transmission on the uplink data transmission frequency resources, and ensuring the peak rate of the uplink data or the uplink data reception performance.

Fifteenth embodiment

The present example provides an access network device, which may be a base station device, such as an evolved node b (eNodeB) or similar device. Although the present embodiment describes the technical solution with uplink control information, those skilled in the art can understand that the solution of the present embodiment can be applied to the transmission of other uplink information based on the same principle and concept. For a specific implementation process, refer to a method implemented by the terminal embodiment in the thirteenth embodiment.

As shown in fig. 32, the access network device 1500 includes:

a processing unit 1501, configured to determine at least two sub-bands, where each sub-band includes at least one frequency resource, and a bandwidth of each sub-band is less than or equal to a bandwidth supported by a terminal;

the processing unit 1501 is further configured to determine third frequency resource information according to a subband region physical uplink control channel resource index, where the third frequency resource information indicates a third frequency resource in frequency resources included in the at least two subbands, and the subband region physical uplink control channel resource index indicates a physical uplink control channel resource in the at least two subbands;

the processing unit 1501 is further configured to map a physical uplink control channel to the third frequency resource;

a transceiving unit 1502, configured to receive the uplink control information through the physical uplink control channel.

By determining at least two sub-bands, determining the corresponding frequency resource mapping and receiving the uplink control information, the received uplink control information can be limited within the sub-bands, i.e. within the bandwidth supported by the sending device, thereby ensuring that the limited terminal transmits the uplink control information, being beneficial to avoiding the uplink control information from dividing the frequency resources in the uplink system bandwidth into several parts, and further ensuring the peak rate of uplink data and the receiving performance of the uplink data. Optionally, the processing unit may determine at least two sub-bands and may determine an even number of sub-bands, such as: 2 subbands, 4 subbands, 6 subbands. To identify the different subbands, a subband index may be used. A sub-band may also have a minimum wideband frequency resource index of the frequency resources contained by the sub-band, a maximum wideband frequency resource index of the frequency resources contained by the sub-band, and a center frequency resource index of the frequency resources contained by the sub-band. Therefore, the processing unit may determine first information of the at least two sub-bands, the first information of the sub-bands including at least one of: a subband index, a minimum wideband frequency resource index of the frequency resources contained in the subband, a maximum wideband frequency resource index of the frequency resources contained in the subband, and a center frequency resource index of the frequency resources contained in the subband. Through the first information of the sub-band, the relevant characteristics of the sub-band can be known, i.e. the sub-band is determined. Such as the width of the sub-band, all frequency resources of the sub-band.

Optionally, when there are two or more terminals, the terminal is divided into a plurality of terminal pairs, and each terminal pair includes a first terminal and a second terminal. And the third frequency resource indicated by the third frequency resource information of the first terminal determined by the processing unit is symmetrical to the third frequency resource indicated by the third frequency resource information determined by the second terminal relative to the center frequency of the system bandwidth. Therefore, when the terminal with limited transmission bandwidth transmits the uplink control information, the uplink control information divides the frequency resource in the uplink system bandwidth into a plurality of parts, thereby ensuring that the uplink data occupies continuous frequency resources and achieving the peak rate of the uplink data.

How the sub-bands are determined is explained below. The processing unit determines at least two sub-bands, and can determine first information of the first sub-band; and then determining the second sub-band according to the first information of the first sub-band. Or, in the case that the first sub-band is known, the characteristic of the second sub-band can be known according to the symmetrical characteristic of the first sub-band and the second sub-band with respect to the center frequency of the system bandwidth.

The receiving and sending unit is configured to send a system information block SIB, where the system information block SIB includes configuration information of the first subband. So that the terminal may determine the second sub-band based on the first information of the first sub-band.

For example, when the first information of the first sub-band is a sub-band index of the first sub-band and the first information of the second sub-band is a sub-band index of the second sub-band, and the sub-band index of the first sub-band and the sub-band index of the second sub-band are consecutive natural numbers, the processing unit determines the sub-band index of the first sub-band, and determines that the sub-band index of the second sub-band is a sub-band index of the first sub-band plus 1 or minus 1 according to the sub-band index of the first sub-band. For example, if the subband index of the first subband is even and the subband index of the second subband is the smallest odd number larger than the subband index of the first subband, the processing unit determines the subband index of the first subband, and determines that the subband index of the second subband is the subband index of the first subband plus 1 according to the subband index of the first subband. The processing unit may determine the second subband based on a subband index of the second subband.

Wherein the content of the first and second substances,

In this way, the transceiver unit transmits a system information block SIB including configuration information of the first subband, so that the terminal may determine the second subband according to the first information of the first subband. Signaling overhead for configuring the first information of the first sub-band and the second sub-band by the base station is saved.

The processing unit may determine third frequency resource information according to a subband region physical uplink control channel resource index, including:

alternatively, the first and second electrodes may be,

For example X is n_sf. And for example X is 10X SFN + n_sfSFN is the radio frame number. For another example, X is the number of subframes included between the starting subframe for transmitting the uplink control information and the current subframe or the number of uplink subframes. The frequency resource mapped by the physical uplink control channel may change, which is called physical uplink control channel frequency hopping. The frequency resource mapped by the physical uplink control channel changes once every G subframes, which is called as physical uplink control channel frequency hopping granularity. The change rule of the frequency resource mapped by the physical uplink control channel is repeated once every H subframes, and then the H subframes are called as a frequency hopping period of the physical uplink control channel. For example, Y is the physical uplink control channel hopping granularity. Physical uplink control channel hoppingThe frequency may occur in a plurality of subframes where a physical uplink control channel is mapped or where the receiving unit receives uplink control information. That is, the receiving unit receives the same uplink control information in a plurality of subframes before and after the frequency resource mapped to the physical uplink control channel changes. X and Y determine the time of frequency hopping of the physical uplink control channel.

The access network equipment of the embodiment of the invention maps the physical uplink control channel into one sub-band of one sub-frame, so that the frequency width mapped by one sub-frame does not exceed the bandwidth of a sending signal supported by a terminal with low complexity or low cost, and the terminal can be ensured to send uplink control information. By the determination or change mode of the third frequency resource information in this embodiment, it can be ensured that the frequency resources mapped before and after the frequency hopping of the physical uplink control channel are symmetric with respect to the center of the system bandwidth, thereby reducing the fragmentation of the uplink control information transmission on the uplink data transmission frequency resources, and ensuring the peak rate of the uplink data or the uplink data reception performance.

Sixteenth embodiment

The present example provides a communication method. Although the present embodiment describes the technical solution with uplink control information, those skilled in the art can understand that the solution of the present embodiment can be applied to the transmission of other uplink information based on the same principle and concept. For a specific implementation process, reference may be made to a method implemented by the apparatus embodiment in the fifteenth embodiment.

As shown in fig. 33, the method includes:

step 1601, determining at least two sub-bands, where the sub-bands include at least one frequency resource, and a bandwidth of each sub-band is less than or equal to a bandwidth supported by a terminal;

step 1602, determining third frequency resource information according to a sub-band region physical uplink control channel resource index, where the third frequency resource information indicates a third frequency resource in frequency resources included in the at least two sub-bands, and the sub-band region physical uplink control channel resource index indicates a physical uplink control channel resource in the at least two sub-bands;

step 1603, mapping a physical uplink control channel to the third frequency resource;

step 1604, receiving the uplink control information through the physical uplink control channel.

By determining at least two sub-bands, determining the corresponding frequency resource mapping and receiving the uplink control information, the received uplink control information can be limited within the sub-bands, i.e. within the bandwidth supported by the sending device, thereby ensuring that the limited terminal transmits the uplink control information, being beneficial to avoiding the uplink control information from dividing the frequency resources in the uplink system bandwidth into several parts, and further ensuring the peak rate of uplink data and the receiving performance of the uplink data.

Alternatively, it may be determined that at least two subbands may determine an even number of subbands, such as: 2 subbands, 4 subbands, 6 subbands. To identify the different subbands, a subband index may be used. A sub-band may also have a minimum wideband frequency resource index of the frequency resources contained by the sub-band, a maximum wideband frequency resource index of the frequency resources contained by the sub-band, and a center frequency resource index of the frequency resources contained by the sub-band. Therefore, first information of the at least two sub-bands is determined, the first information of the sub-bands comprises at least one of the following: a subband index, a minimum wideband frequency resource index of frequency resources contained in the subband, a maximum wideband frequency resource index of frequency resources contained in the subband, and a center frequency resource index of frequency resources contained in the subband.

Optionally, when there are two or more terminals, the terminal is divided into a plurality of terminal pairs, and each terminal pair includes a first terminal and a second terminal. The third frequency resource indicated by the third frequency resource information of the first terminal and the third frequency resource indicated by the third frequency resource information of the second terminal are symmetrical with respect to the center frequency of the system bandwidth. Therefore, when the terminal with limited transmission bandwidth transmits the uplink control information, the uplink control information divides the frequency resource in the uplink system bandwidth into a plurality of parts, thereby ensuring that the uplink data occupies continuous frequency resources and achieving the peak rate of the uplink data.

I.e. determining first information of said first subband; and determining the second sub-band according to the first information of the first sub-band.

The method also includes transmitting a system information block SIB containing configuration information of first information of the first subband. So that the terminal may determine the second sub-band based on the first information of the first sub-band.

For example, when the first information of the first sub-band is a sub-band index of the first sub-band and the first information of the second sub-band is a sub-band index of the second sub-band, and the sub-band index of the first sub-band and the sub-band index of the second sub-band are consecutive natural numbers, the sub-band index of the first sub-band is determined, and the sub-band index of the second sub-band can be determined to be the sub-band index of the first sub-band plus 1 or minus 1 according to the sub-band index of the first sub-band. For example, if the subband index of the first subband is even and the subband index of the second subband is the smallest odd number larger than the subband index of the first subband, the subband index of the first subband is determined, and the subband index of the second subband is determined to be the subband index of the first subband plus 1 according to the subband index of the first subband. The second subband may be determined based on the subband index of the second subband.

For another example, when the first information of the first sub-band is the minimum wideband frequency resource index of the frequency resources included in the first sub-band, and the first information of the second sub-band is the minimum wideband frequency resource index of the frequency resources included in the second sub-band, it is determined that the minimum wideband frequency resource index of the frequency resources included in the first sub-band is f_{NB1_min}Then, the minimum wideband frequency resource index of the frequency resource contained in the second sub-band can be determined as

Wherein the content of the first and second substances,

Through the above manner, the system information block SIB is sent, where the system information block SIB includes configuration information of the first subband, so that the terminal may determine the second subband according to the first information of the first subband. Signaling overhead for configuring the first information of the first sub-band and the second sub-band by the base station is saved.
