S201, the network equipment determine the MCS communicated with terminal.

In the present embodiment, MCS contains encoder bit rate information and modulation system information, and the network equipment for example can be according to end The CQI (such as noise receives reliability requirement etc. than condition, the data of terminal transmission, end-on) etc. reported is held, determines network The MCS that equipment is communicated with terminal.MCS that the network equipment is communicated with terminal is also possible to either be used for the MCS of uplink communication Both for the MCS of downlink communication, can also include.

S202, the network equipment determine the grain to the terminal distribution for the frequency domain resource of communication according to determining MCS Degree.

In the present embodiment, the network equipment determines the granularity of frequency domain resource according to determining MCS, which is instruction net Frequency domain resource of the network equipment to terminal distribution for communication.Such as: it can be different the grain that MCS corresponds to different frequency domain resources Degree, alternatively, the MCS that can be different groups corresponds to the granularity of different frequency domain resources, every group of MCS includes at least one MCS, this reality Example is applied not limit this.Wherein, the granularity of the frequency domain resource be represented to terminal distribution for communication frequency domain resource Size.

Wherein, the granularity of above-mentioned frequency domain resource can be resource block group (Resource block group, RBG), It is exactly frequency domain resource of the network equipment as unit of resource block group for terminal distribution for communication, each RBG is made of P RB, P For the integer more than or equal to 1.Alternatively,

S203, the network equipment send control information to the terminal.Terminal receives the control letter that the network equipment is sent Breath.

In the present embodiment, the network equipment is determined as the frequency domain of terminal distribution according to the granularity of the frequency domain resource of above-mentioned determination Resource, and be the granularity determined in S202 for the granularity of the frequency domain resource of terminal distribution.Then the network equipment needs to inform It is the frequency domain resource of terminal distribution to terminal, i.e., which corresponding frequency domain resource of described granularity distributes to terminal.Therefore, this reality The network equipment for applying example sends control information to terminal, wherein the control information is, for example, Downlink Control Information (Downlink Control Information, DCI), include resource allocation field in the control information, carries in the resource allocation field as this The information of the frequency domain resource of terminal distribution, the information are, for example, the location information of the frequency domain resource.

Correspondingly, terminal receives the control information that the network equipment is sent.

S204, the terminal determine that the network equipment is used to the terminal distribution according to the domain MCS of the control information In the granularity of the frequency domain resource of communication.

It include the domain MCS in the control information that the above-mentioned network equipment is sent in the present embodiment, terminal passes through parsing control information The domain MCS obtain MCS, be network equipment root since the network equipment is granularity of the terminal distribution for the frequency domain resource of communication It is determined according to MCS, therefore, the MCS that terminal can be indicated based on the domain MCS determines the network equipment to terminal distribution for communication The granularity of frequency domain resource.

S205, the terminal parse the resource allocation field of the control information, determine according to the granularity of the frequency domain resource Information of the terminal for the frequency domain resource of communication.

In the present embodiment, terminal goes the resource point of parsing control information according to the granularity of the frequency domain resource determined in S204 With domain, to obtain the information of frequency domain resource of the terminal carried in resource allocation field for communicating.Such as: the grain of frequency domain resource Degree is bigger, and the bit position obtained in the resource allocation field of parsing control information needed for the information of frequency domain resource is fewer.With frequency domain It include 100 RB in system bandwidth for the granularity of resource is RBG, if RBG (i.e. the granularity of frequency domain resource) is 10 RB, Then system bandwidth is divided into 10 RBG, and the information instruction terminal of 10 bit positions in resource allocation field is correspondingly needed to be used for The information of the frequency domain resource of communication, if such as the 1st bit position information be 1, illustrate the 1st RBG be terminal be used for lead to The frequency domain resource of letter illustrates that the 1st RBG is not frequency domain money of the terminal for communication if the information of the 1st bit position is 0 Source.If RBG (i.e. the granularity of frequency domain resource) is 20 RB, system bandwidth is divided into 5 RBG, correspondingly needs resource point Information of the information instruction terminal with 5 bit positions in domain for the frequency domain resource of communication.Therefore, according to the grain of frequency domain resource Degree, can determine the information that several bit positions are parsed in resource allocation field, so that it may obtain terminal for communication frequency domain The information of resource.

Fig. 3 is the flow chart for the communication means that another embodiment of the application provides, as shown in figure 3, the method for the present embodiment May include:

S301, the network equipment determine the MCS communicated with terminal.

In the present embodiment, the specific implementation process of S301 may refer to the associated description in embodiment illustrated in fig. 2, herein not It repeats again.

S302, when determining MCS belongs to the first MCS set, network equipment determination is used for the terminal distribution The granularity of the frequency domain resource of communication is the first granularity；When determining MCS belongs to the 2nd MCS set, the network equipment is determined The granularity of frequency domain resource to the terminal distribution for communicating is the second granularity.

There are the first MCS set and the 2nd MCS set in the present embodiment, and the first MCS set includes at least one MCS, the 2nd MCS set also include at least one MCS, and the first MCS set integrates with the 2nd MCS intersection of sets as empty set.It is real one It applies in example, the corresponding code rate of any one MCS in the first MCS set is respectively less than any one MCS institute in the 2nd MCS set Corresponding code rate.Wherein, the corresponding encoder bit rate of different MCS can not also be identical, it is however generally that, for identical modulation methods Formula, encoder bit rate is smaller, indicates that the index of the MCS of the encoder bit rate also can be smaller.After the network equipment determines MCS, determine The MCS belongs to the first MCS set or the 2nd MCS set, when determining MCS belongs to the first MCS set, it is also assumed that should The corresponding encoder bit rate of MCS is less than default first encoder bit rate, and the network equipment determines the frequency domain to the terminal distribution for communication The granularity of resource is the first granularity；When determining MCS belongs to the 2nd MCS set, it is also assumed that the corresponding coding code of the MCS Rate is more than or equal to default first encoder bit rate, and the network equipment determines that the granularity to the terminal distribution for the frequency domain resource of communication is Second granularity.

For the same transmission block, under identical modulation system, encoder bit rate is smaller, indicates that required interface-free resources are got over More, correspondingly, required frequency domain resource is more, if using lesser granularity when distributing frequency domain resource, needs more The information of bit position is used to indicate the position for distributing to the frequency domain resource of terminal, but if when distributing frequency domain resource using compared with Big granularity is used to distribute, then less bit position is needed to be used to indicate the position for distributing to the frequency domain resource of terminal；Cause This for distributing, then may not need using the frequency domain resource of higher granularity and increase bit position, so that it may which end is distributed in instruction The position of the frequency domain resource at end.Therefore, above-mentioned first granularity in the present embodiment is greater than the second granularity.

In some embodiments, when the MCS of the determination belongs to the first MCS set, the network equipment also determines institute Stating the first granularity includes N number of RB；When the MCS of the determination belongs to the 2nd MCS set, the network equipment also determines second Degree includes M RB.Moreover, N is greater than M.Wherein, the information of the frequency domain resource with the second granularity occupies in the resource allocation field All bit positions, the information of frequency domain resource with the first granularity occupies the partial bit position in the resource allocation field It sets.

S303, the network equipment send control information to the terminal.Terminal receives the control letter that the network equipment is sent Breath.

In the present embodiment, the specific implementation process of S303 may refer to the associated description in embodiment illustrated in fig. 2, herein not It repeats again.

In some embodiments, the network equipment sends the index of the MCS of above-mentioned determination to terminal.Wherein, the index of the MCS Terminal can be sent to by above-mentioned control information, wherein carrying the index of the MCS in control information may include such as lower section Formula.

In some embodiments, the information of the frequency domain resource with the second granularity occupies the institute in the resource allocation field There is bit position, the information of the frequency domain resource with the first granularity occupies the partial bit position in the resource allocation field, such as Q A bit position.The network equipment also determines whether the MCS of above-mentioned determination belongs to the 3rd MCS set, wherein the 3rd MCS set For above-mentioned first MCS set subset, such as: the 3rd MCS set be the first MCS set, alternatively, the 3rd MCS gather For the proper subclass of the first MCS set.

When the MCS of above-mentioned determination belongs to the 3rd MCS set, indicate that the corresponding encoder bit rate of the MCS is less than or equal to the domain MCS Minimum encoder bit rate corresponding to indicated MCS illustrates that the bit position in the domain MCS is fewer than the rope for indicating the MCS Draw, but also be represented to terminal distribution for communication frequency domain resource granularity be the first granularity, under the first granularity, resource divide It is sufficiently used for being indicated to the position of the frequency domain resource of terminal distribution with the bit position in domain, illustrates to provide for the frequency domain of terminal distribution The information in source occupies the partial bit position of resource allocation field, such as Q bit position, and the resource allocation field is in addition to for referring to Except the bit position for showing the position of the frequency domain resource, extra bit position is also had.It follows that being deposited in resource allocation field In extra bit position, but inadequate bit position is used to indicate the index of MCS in the domain MCS, and therefore, the network equipment is to terminal The index for sending the MCS occupies preset K bit position in the resource allocation field, and the K is the integer more than or equal to 1. In some embodiments, the bit position in the resource allocation field in addition to the K bit position is used to indicate frequency domain money The information in source includes Q+K bit position that is, in resource allocation field, wherein K bit position is used to indicate the index of MCS, separately Outer Q bit position is used to indicate the information of frequency domain resource.Therefore, the present embodiment is by bit position extra in resource allocation field Be used to indicate the index of the MCS so that the bit position in resource allocation field is effectively utilized, and the domain MCS without It is further added by bit position, avoids the size for increasing control information.

When the MCS of above-mentioned determination is not belonging to the 3rd MCS set, indicate that the encoder bit rate of MCS instruction is greater than or equal to Minimum encoder bit rate corresponding to MCS indicated by the domain MCS illustrates that the bit position in the domain MCS is sufficiently used for indicating the MCS's Index, also illustrates that the index of the MCS is not take up the bit position in resource allocation field.What then the network equipment was sent to terminal should The index of MCS occupies the domain MCS in the control information.

In some embodiments, when the MCS that the network equipment determines belongs to the 3rd MCS set, the index of the MCS is accounted for With K bit position of resource allocation field, and the bit position in the domain MCS no longer indicates the index of the MCS, therefore, the net Network equipment fills preset index in the domain MCS of the control information, and the preset index is used to indicate need to be from the money The index of the MCS of the determination is parsed in the distribution domain of source.Such as: the preset index is call number 0 or reserved MCS rope Quotation marks.

When S304, the index indicated by the domain MCS belong to the first MCS index set, the terminal determines the net Network equipment is the first granularity for the granularity of the frequency domain resource of communication to the terminal distribution；The rope indicated by the domain MCS Draw belong to the 2nd MCS index set when, the terminal determine the network equipment to the terminal distribution for communication frequency domain The granularity of resource is the second granularity.

In the present embodiment, terminal can obtain index indicated by the domain MCS according to the domain MCS in parsing control information.So It determines that index indicated by the domain MCS obtained belongs to the first MCS index set and still falls within the 2nd MCS index set afterwards, works as MCS When index indicated by domain belongs to the first MCS index set, the terminal determines that the network equipment is used to the terminal distribution In communication frequency domain resource granularity be the first granularity；The index indicated by the domain MCS belongs to the 2nd MCS index set When, the terminal determines that the granularity of frequency domain resource of the network equipment to the terminal distribution for communicating is the second granularity.

In some embodiments, any one MCS index in the first MCS index set is respectively less than described second Any one MCS index in MCS index set, first granularity are greater than the second granularity.

When the index indicated by the domain MCS belongs to the first MCS index set, indicate index indicated by the domain MCS be less than (or Person is less than or equal to) the first MCS index is preset, but also presentation code code rate is less than (or being less than or equal to) first pre-arranged code code Rate, terminal determine that the granularity of frequency domain resource of the network equipment to terminal distribution for communicating is coarseness, that is, the first granularity. When the index indicated by the domain MCS belongs to the 2nd MCS index set, it is (or big to indicate that index indicated by the domain MCS is more than or equal to In) the first MCS index is preset, but also presentation code code rate is more than or equal to (or being greater than) first pre-arranged code code rate, terminal The granularity for determining frequency domain resource of the network equipment to terminal distribution for communicating is fine granularity, that is, the second granularity.

S305, the terminal parse the resource allocation field of the control information, determine according to the granularity of the frequency domain resource Information of the terminal for the frequency domain resource of communication.

In the present embodiment, the specific implementation process of S305 may refer to the associated description of embodiment illustrated in fig. 2, herein no longer It repeats.

In some embodiments, terminal is also according to the domain MCS, the determining index with the MCS of network device communications.In addition, The terminal of the present embodiment can also determine the size of TBS, can also determine encoder bit rate, specifically according to the index of the MCS of acquisition Similarly to the prior art, details are not described herein again for realization process.

Wherein, how terminal determines that the index of MCS has such as under type.

In some embodiments, the domain MCS in terminal parsing control information, can obtain index indicated by the domain MCS, Then determine whether the index of the domain MCS instruction belongs to the 3rd MCS index set, wherein the 3rd MCS indexed set is combined into above-mentioned The subset of first MCS index set, such as: the 3rd MCS indexed set is combined into the proper subclass of the first MCS index set, alternatively, 3rd MCS indexed set is combined into the first MCS index set itself.In some embodiments, in the 3rd MCS index set The index of MCS be less than (being perhaps less than or equal to) preset the 2nd MCS index but also presentation code code rate be less than (or less than etc. In) the second encoder bit rate is preset, it presets the second encoder bit rate and is less than or equal to default first encoder bit rate.Wherein, this default the Two MCS indexes are less than or equal to above-mentioned default first MCS index, if the default 2nd MCS index is less than default first MCS rope Draw, then the 3rd MCS indexed set is combined into the proper subclass of the first MCS index set, if the default 2nd MCS index, which is equal to, presets the One MCS index, then the 3rd MCS indexed set is combined into the first MCS index set itself.In one embodiment, in identical modulation Under mode, the corresponding encoder bit rate of lesser MCS index is smaller, and the corresponding encoder bit rate of biggish MCS index is larger.

, can be prespecified in the present embodiment, when the index of the domain MCS instruction belongs to the 3rd MCS index set, the MCS Index occupy resource allocation field in preset K bit position；And/or the index of the domain MCS instruction is not belonging to the 3rd MCS rope When drawing set, the index of the MCS occupies the domain MCS.

Index due to being more than or equal to the MCS of default 2nd MCS index occupies the bit position in the domain MCS, terminal Interpret the domain MCS, so that it may obtain the index of the MCS, the index of the MCS is more than or equal to default 2nd MCS index.It is pre- due to being less than If the index of the MCS of the 2nd MCS index occupies the bit position of resource allocation field, therefore, terminal is first interpreted the domain MCS and is interpreted again Resource allocation field specifically interprets K bit position in resource allocation field, so that it may the index of the MCS is obtained, the MCS's Index is less than default 2nd MCS index.

When terminal determines that the index that the domain MCS indicates belongs to the 3rd MCS index set, illustrate there is portion in resource allocation field The information of point bit position is used to indicate the index of MCS, and terminal is according to the letter on K bit position preset in resource allocation field The determining index with the MCS of the network device communications of breath.In some embodiments, except the K in the resource allocation field Bit position except bit position is used to indicate the information of frequency domain resource, such as resource allocation field includes T bit position altogether, Wherein preset K bit position is used to indicate the index of MCS, and correspondingly, Q bit position is used to indicate as terminal distribution The information of frequency domain resource, the Q=T-K.Therefore, bit position idle in resource allocation field is used in the present embodiment for referring to The index for showing MCS without increasing the bit position in the domain MCS, and then avoids the size for increasing control information.

When the index of the domain MCS instruction is not belonging to the 3rd MCS index set, illustrate that the index of MCS occupies the domain MCS, And the index for not having bit position to be used to indicate MCS in resource allocation field, terminal determine that index indicated by the domain MCS is Index for terminal and the MCS of the network device communications.

In some embodiments, the index of the MCS in the 3rd MCS index set is used to indicate the index of real MCS (i.e. The index of MCS used by terminal and the network device communications) bit position in resource allocation field is occupied, it need to be from described The index with the MCS of network device communications is parsed in resource allocation field.Therefore, when terminal determines rope indicated by the domain MCS Draw when belonging to the 3rd MCS index set, terminal index according to indicated by the domain MCS is determined and needed from the resource Distribute parsing in domain the index with the MCS of network device communications.Optionally, the 3rd MCS index set includes index 0.

In some embodiments, when terminal determines that the index that the domain MCS indicates belongs to the first MCS index set, institute It states terminal and also determines that first granularity includes N number of RB, for terminal according to the first granularity, parsing controls resource allocation field in information The information of Q bit position, determine terminal for communication frequency domain resource information；It is indicated in the domain MCS that terminal determines Index belong to the 2nd MCS index set when, the terminal also determine the second granularity include M RB, the terminal is according to second Granularity, resolving resource distribute domain all bit positions, determine terminal for communication frequency domain resource information.Wherein, N is greater than M。

On the basis of the various embodiments described above, in some embodiments, the index of the MCS in the 4th MCS index set is used The granularity of frequency domain resource in the instruction network equipment to the terminal distribution for communicating is the first granularity.Described in terminal determines After index indicated by the domain MCS, also determine whether index indicated by the domain MCS belongs to the 4th MCS index set, when this When index indicated by the domain MCS belongs to the 4th MCS index set, the terminal determines the network equipment to the terminal distribution The granularity of frequency domain resource for communication is the first granularity, wherein the 4th MCS index set and the first MCS index Intersection of sets integrates as empty set, and intersection of the 4th MCS index set in conjunction with the 2nd MCS index is also empty set.It is optional Ground, when the domain MCS instruction index be not belonging to the 4th MCS index set when, terminal can by the domain MCS indicate index and First MCS index set, the 2nd MCS index set are compared, to determine the network equipment to the terminal distribution for communicating Frequency domain resource granularity, specific implementation process may refer to foregoing description, and details are not described herein again.

In some embodiments, the index that the index of the MCS in the 4th MCS index set is used to indicate real MCS accounts for With the bit position in resource allocation field, need to information from the resource allocation field on preset K bit position, parsing With the index of the MCS of network device communications.Therefore, when terminal determines that index indicated by the domain MCS belongs to the 4th MCS When index set, terminal is determined according to the information on K bit position preset in the resource allocation field and is set with the network The index of the MCS of standby communication.Optionally, the 4th MCS index set includes reserved MCS call number, for example, call number 29 or 30 or 31, the present embodiment is not limited to this.

It include call number 0 with the 3rd MCS index set, above-mentioned 4th MCS index set includes that reserved MCS call number is Example is illustrated.It is, when terminal obtain the domain MCS indicated by index be call number 0 when, the call number 0 is no longer Indicate a kind of MCS, but rather indicate that the index of MCS need to be parsed from the resource allocation field, therefore, the distribution of terminal resolving resource The information of preset K bit position in domain, the information that parsing is obtained is as the index of MCS.When the domain the MCS institute that terminal obtains When the index of instruction is reserved MCS call number, terminal can determine that the reserved MCS call number is not real MCS Index, then again resolving resource distribution domain in preset K bit position information, will parsing acquisition information as MCS's Index.The index indicated by the domain MCS that terminal obtains neither call number 0 nor reserved MCS call number, then explanation should Index indicated by the domain MCS is exactly the index of real MCS, and then terminal is by index indicated by the domain MCS as the MCS's Index.

In addition, in the above-described embodiments, it is mainly smaller with the index of the MCS under identical modulation system, to indicate to compile Code code rate is smaller, but can also be bigger with the index of the MCS under identical modulation system, and it is smaller to carry out presentation code code rate.? In other embodiments, any one MCS index in the first MCS index set is all larger than the 2nd MCS indexed set Any one MCS index in conjunction, first granularity are greater than second granularity.

In some embodiments, when the index indicated by the domain MCS belongs to the first MCS index set, indicate that the domain MCS is signified The index shown be greater than (being perhaps more than or equal to) preset the 3rd MCS index but also presentation code code rate be less than (or less than etc. In) the first pre-arranged code code rate, terminal determine the network equipment to terminal distribution for communication frequency domain resource granularity be coarse grain Degree, that is, the first granularity.When the index indicated by the domain MCS belongs to the 2nd MCS index set, indicate indicated by the domain MCS Index is less than or equal to (being perhaps less than) and presets the 3rd MCS index but also presentation code code rate more than or equal to (or being greater than) the One pre-arranged code code rate, terminal determine that the granularity of frequency domain resource of the network equipment to terminal distribution for communicating is fine granularity, It is exactly the second granularity.In the case where the judgement granularity, other further embodiments are similar with the description above scheme, Ke Yican See the record in the various embodiments described above, details are not described herein again.

Below it is the example for showing MCS index in table form, as shown in Table 1, is carried out in conjunction with table a pair of embodiment Description.In application, MCS table shown in table one can be referred to as the first MCS table.

Table one

For convenience, the present embodiment is to be divided into the first MCS index set for call number 0, i.e., the 3rd MCS indexed set is combined into first MCS index set itself, at this time it is considered that table one is divided into three index set, call number 0 is the first MCS index set (i.e. the 3rd MCS index set), call number 1-28 are the 2nd MCS index set, reserved MCS call number (i.e. call number 29- 30) gather for the 4th MCS index.

When index indicated by terminal determines the domain MCS is call number 0, then terminal determines the network equipment to the end End distribution is the first granularity for the granularity of the frequency domain resource of communication, and determines that the call number 0 is not used to terminal and net The index of the MCS of network equipment communication, then terminal resolving resource distributes the information of preset K bit position in domain, is used In the index of terminal and the MCS of network device communications.When terminal determine the domain MCS indicated by call number be call number 1 to 28 In any one call number when, then terminal determines that call number indicated by the domain MCS is for terminal and network device communications The index of MCS.When terminal determine the domain MCS shown in call number be call number 29 to 31 in any one call number when, then eventually End determines that the granularity of frequency domain resource of the network equipment to the terminal distribution for communicating is the first granularity, and determining should Call number 0 is not used to the index of the MCS of terminal and network device communications, then preset in terminal resolving resource distribution domain The information of K bit position obtains the index of the MCS for terminal and network device communications.

In some embodiments, call number 0-31 points can be first by the index list based on MCS shown in table one MCS index set and the 2nd MCS index set.Wherein, by reserved MCS call number, also call number 29,30,31 is divided For the first MCS index set, the call number 0-28 in table one is divided into the 2nd MCS index set.

When index indicated by terminal determines the domain MCS is any one call number in call number 29 to 31, then terminal is true The granularity of frequency domain resource of the fixed network equipment to the terminal distribution for communication is the first granularity, and determines the domain MCS Indicated index is not used to the index of the MCS of terminal and network device communications, then in terminal resolving resource distribution domain The information of preset K bit position obtains the index of the MCS for terminal and network device communications.As the MCS that terminal determines When call number indicated by domain is any one call number in call number 0 to 28, then terminal determines index indicated by the domain MCS Number for index for terminal and the MCS of network device communications.

When the index of the MCS to go together for terminal and the network equipment is parsed from resource allocation field to be obtained, terminal can be with The MCS for obtaining it with network device communications according to the 2nd MCS table that the index goes lookup to pre-save.Wherein, the 2nd MCS table MCS indicated by each index in lattice in MCS indicated by each index and the first MCS table is different, or at most only One is sample.In the first MCS table of the application and the 2nd MCS table can be as defined in standard or the network equipment Reciprocally negotiated with terminal it is determining, can also have other way determine.As for the first MCS table and the 2nd MCS table Lattice how to determine and table in value of the parameters under different index, the application is not construed as limiting.

When parsed from the domain MCS for the index of terminal and the MCS of network device communications obtain when, terminal device is searched pre- The MCS that the first MCS table first saved obtains it with network device communications.
