Embodiment

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

The embodiment of the invention provides a kind of implementation method, device and communication system of frequency hopping.Below be elaborated respectively.

Embodiment one,

Present embodiment will be described from the angle of the network equipment, and this network equipment specifically can be eNodeB, perhaps for having other network entities with the eNodeB similar functions.

A kind of implementation method of frequency hopping comprises: it is the Synthesized Frequency Hopping pattern that frequency-hopping mode is set, and frequency hopping type is set is Class1; Obtain ascending resource total bandwidth and the bandwidth of keeping for the PUCCH channel; According to ascending resource total bandwidth and bandwidth poor of keeping for the PUCCH channel, calculate the bandwidth of distributing to the PUSCH channel; Bandwidth, frequency-hopping mode and frequency hopping type according to the PUSCH channel that calculates carry out the distribution of ascending resource.

Schematic flow sheet referring to Fig. 2 comprises the steps:

101, frequency-hopping mode being set is the Synthesized Frequency Hopping pattern, and frequency hopping type is set is Class1.

Wherein, The Synthesized Frequency Hopping pattern refers to the Synthesized Frequency Hopping pattern that adds in the TTI between TTI; Class1 (Type1) is meant that the ascending resource information of sending according to eNodeB of giving carries out the type of frequency hopping (referring to the explanation in the background technology), and concrete setting can be repeated no more at this referring to prior art.

102, obtain ascending resource total bandwidth and keep for the bandwidth of PUCCH channel, perhaps, obtain the actual shared bandwidth of ascending resource total bandwidth and PUCCH channel.

Wherein, obtain the bandwidth of keeping for the PUCCH channel and can adopt following method:

Obtain the actual shared bandwidth of PUCCH channel; If the actual shared bandwidth of the PUCCH channel that gets access to is an odd number, then the actual shared bandwidth of PUCCH channel is added 1 bandwidth unit as the bandwidth of keeping for the PUCCH channel; If the actual shared bandwidth of the PUCCH channel that gets access to is an even number, then with the actual shared bandwidth of PUCCH channel as the bandwidth of keeping for the PUCCH channel.

For example, bandwidth all representes with the RB number, For keeping for the RB number of PUCCH channel, N _RB ^HOBe the actual shared RB number of PUCCH channel, then can use following formulate:

Work as N _RB ^HODuring for odd number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}+1;$

Work as N _RB ^HODuring for even number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}.$

Wherein, the concrete acquisition methods of the actual shared bandwidth of ascending resource total bandwidth and PUCCH channel can repeat no more at this referring to prior art.

What need explanation is that the execution sequence of step 101 and step 102 can be in no particular order.

103, the ascending resource total bandwidth that step 102 is got access to is poor with the bandwidth of keeping for the PUCCH channel, as the bandwidth of distributing to the PUSCH channel.

For example, bandwidth is all represented with the RB number, N _RB ^PUSCHThe RB number of PUSCH channel is distributed in expression,

For keeping for the RB number of PUCCH channel, N _RB ^ULBe the RB total number that ascending resource had, N _RB ^HOBe the actual shared RB number of PUCCH channel, the RB number of then distributing to the PUSCH channel is formulated as:

$N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-{\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}};$

Perhaps, in order to utilize idle RB more fully, better improve the utilance of band resource, ascending resource total bandwidth that also can step 102 be got access to and the actual shared bandwidth of PUCCH channel poor is as the bandwidth of distributing to the PUSCH channel;

Equally, for example, bandwidth is all represented with the RB number, N _RB ^PUSCHThe RB number of PUSCH channel, N are distributed in expression _RB ^ULBe the RB total number that ascending resource had, N _RB ^HOBe the actual shared RB number of PUCCH channel, the RB number of then distributing to the PUSCH channel is formulated as:

$N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-N_{\mathrm{RB}}^{\mathrm{HO}}.$

What need explanation is that when distributing bandwidth, some bandwidth may be distributed to RACH (RACH; Random Access Channel), still, RACH is not that each subframe all has; It carries out the periodicity assignment by high level; If there is RACH, then also need deduct the shared bandwidth of RACH again, be about to the bandwidth that the PUSCH channel is distributed in ascending resource total bandwidth and the poor conduct of " the actual occupied bandwidth of PUCCH channel and RACH bandwidth with "; Perhaps; The difference of ascending resource total bandwidth and " bandwidth of keeping for the PUCCH channel with RACH bandwidth with " as the bandwidth of distributing to the PUSCH channel, because whether RACH exist and do not influence this scheme, so is all supposed not exist RACH in embodiments of the present invention.

104, the bandwidth of distributing to the PUSCH channel that calculates according to step 103, and the frequency-hopping mode and frequency hopping type collocating uplink resource allocation information and the frequency hopping information that are provided with in the step 101.

105, send ascending resource and give signaling (UL Grant) to the terminal, wherein, this ascending resource is given and is carried ascending resource assignment information and frequency hopping information in the signaling.

Further; The method that present embodiment provides can also comprise that issuing broadcast gives the terminal, wherein; Broadcast indication current area is supported the Synthesized Frequency Hopping pattern, sends upstream data so that signaling is given according to this broadcast and the ascending resource that receives in the terminal.

By on can know; Present embodiment adopts poor with ascending resource total bandwidth and the bandwidth of keeping for the PUCCH channel, and perhaps poor with ascending resource total bandwidth and the shared bandwidth of PUCCH channel reality is as the bandwidth of distributing to the PUSCH channel; Make the idle bandwidth of PUCCH channel; Be that idle RB can fully be used, avoid using the frequency hopping gain that is caused to descend because idle RB can't distribute to the PUSCH channel, and the problem of the waste of band resource.

For example, if the ascending resource total bandwidth $N_{\mathrm{RB}}^{\mathrm{UL}}=25,$ The actual shared bandwidth of PUCCH channel $N_{\mathrm{RB}}^{\mathrm{HO}}=5,$ Then keep for the bandwidth of PUCCH channel ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=6,$ If according to the scheme of prior art, then can further draw the bandwidth of distributing to the PUSCH channel $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=18,$ So, as shown in Figure 1, sequence number is that 7 and 8 RB resource can't be as the initial RB position of frequency hopping among Fig. 1, and according to the scheme that present embodiment provided, then can obtain distributing to the bandwidth of PUSCH channel $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=19,$ It is thus clear that except the bandwidth of keeping for the PUCCH channel, remaining bandwidth all can be distributed to the PUSCH channel.

Perhaps, again for example, if the ascending resource total bandwidth $N_{\mathrm{RB}}^{\mathrm{UL}}=25,$ The actual shared bandwidth of PUCCH channel $N_{\mathrm{RB}}^{\mathrm{HO}}=5,$ Then distribute to the bandwidth of PUSCH channel $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=20,$ It is thus clear that except the actual shared bandwidth of PUCCH channel, remaining bandwidth all can be distributed to the PUSCH channel; In terms of existing technologies, improved the frequency hopping gain, and the utilance of band resource.

Embodiment two,

According to embodiment one described method, in the present embodiment, will be that eNodeB is that example is done further explain with the network equipment.

Bandwidth is represented with the RB number, N _RB ^PUSCHThe RB number of PUSCH channel is distributed in expression, and

The RB number of PUCCH channel, N are kept in expression _RB ^ULThe expression RB total number that ascending resource had, N _RB ^HOThe actual shared RB number of expression PUCCH channel, then:

$N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-{\tilde{U}}_{\mathrm{RB}}^{\mathrm{HO}},$ Perhaps, $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-N_{\mathrm{RB}}^{\mathrm{HO}};$

Wherein, is:

Work as N _RB ^HODuring for odd number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}+1;$

Work as N _RB ^HODuring for even number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}.$

Can be referring to Fig. 3 and Fig. 4, if the ascending resource total bandwidth $N_{\mathrm{RB}}^{\mathrm{UL}}=25,$ The actual shared bandwidth of PUCCH channel $N_{\mathrm{RB}}^{\mathrm{HO}}=5,$ Then keep for the bandwidth of PUCCH channel ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=6,$ Then, can by $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-{\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}$ Release $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=19,$ Perhaps, by $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-N_{\mathrm{RB}}^{\mathrm{HO}}$ Release $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=20;$ It is thus clear that visible, except the bandwidth or the actual shared bandwidth of PUCCH channel of keeping for the PUCCH channel, remaining bandwidth all can be distributed to the PUSCH channel.

The method that schematic flow sheet as shown in Figure 5, present embodiment provide can comprise the steps:

201, frequency-hopping mode is set is the Synthesized Frequency Hopping pattern to eNodeB, and issues broadcast, and the indication current area is supported the Synthesized Frequency Hopping pattern in broadcast.

202, frequency hopping type is set is Class1 to eNodeB.

For example, eNodeB gives the frequency hopping information in the resource allocation information of signaling to ascending resource bit (Hopping bit) is provided with, and it is set to the Class1 frequency hopping.

203, eNodeB obtains ascending resource total bandwidth N _RB ^ULWith the bandwidth of keeping for the PUCCH channel

Perhaps, eNodeB obtains ascending resource total bandwidth N _RB ^ULWith the actual shared bandwidth of PUCCH channel.

Wherein, eNodeB obtains ascending resource total bandwidth N _RB ^ULCan directly obtain, and keep for the bandwidth of PUCCH channel

Then can be through obtaining the actual shared bandwidth N of PUCCH channel _RB ^HO, then according to the actual shared bandwidth N of the PUCCH channel that gets access to _RB ^HOCalculate, computational methods are following:

Work as N _RB ^HODuring for odd number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}+1;$

Work as N _RB ^HODuring for even number, ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=N_{\mathrm{RB}}^{\mathrm{HO}}.$

What need explanation is that the execution sequence of step 201, step 202 and step 203 in no particular order.

204, with ascending resource total bandwidth and the difference of bandwidth of keeping for the PUCCH channel as the bandwidth of distributing to PUSCH, perhaps, with differing from of the shared bandwidth of ascending resource total bandwidth and PUCCH channel reality as the bandwidth of distributing to PUSCH.As follows:

ENodeB is according to the ascending resource total bandwidth N that gets access in the step 203 _RB ^ULWith the bandwidth of keeping for the PUCCH channel Utilize formula $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-{\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}},$ Calculate the bandwidth N that distributes to PUSCH _RB ^PUSCHPerhaps,

ENodeB is according to the ascending resource total bandwidth N that gets access in the step 203 _RB ^ULWith the actual shared bandwidth N of PUCCH channel _RB ^HO, utilize formula $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=N_{\mathrm{RB}}^{\mathrm{UL}}-N_{\mathrm{RB}}^{\mathrm{HO}},$ Calculate the bandwidth N that distributes to PUSCH _RB ^PUSCH

205, according to the bandwidth of distributing to the PUSCH channel, and frequency-hopping mode and frequency hopping type collocating uplink resource allocation information and frequency hopping information.As follows:

The bandwidth of distributing to the PUSCH channel that eNodeB calculates according to step 204, and the frequency-hopping mode and frequency hopping type collocating uplink resource allocation information and the frequency hopping information that are provided with in step 201 and the step 202.Wherein, ascending resource assignment information and frequency hopping information can be shown in tables one.

Table one

Type?2?PUSCH?Hopping

Wherein, " System BW " expression system bandwidth in the table one, at present, the general bandwidth of supporting from 6RB～110RB scope of system; " Number of Hopping bits " be the bit number of indicative of frequency hopping information then, and the bit number of this frequency hopping information can be divided into 1 bit and two kinds of situation of dibit, and in the time of in bandwidth is 6～49RB scope, system default frequency hopping information is 1 bit; When bandwidth was 50～110RB, system default frequency hopping information was 2 bits; " Information in Hopping bits " then indicates the information of the bit of relevant frequency hopping information; Corresponding with " Number of Hopping bits "; When frequency hopping information is 1 bit; Then can be divided into " 0 " and " 1 " two kinds of situation; When frequency hopping information is 2 bits, then can be divided into " 00 ", " 01 ", " 10 " and " 11 " four kinds of situation, be directed to this four kinds of situation; Indicated the different calculation methods of the pairing frequency domain position of bit (Hopping-bit)

of frequency hopping information respectively, as follows:

For the Synthesized Frequency Hopping pattern, the initial index (n of the RB of time slot 0 _PRB ^S1(i)) by the initial RB (RB in the resource allocation information _START) indication, the initial index (n of the RB of time slot 1 _PRB(i)) by the pairing frequency domain position of bit (Hopping-bit) of frequency hopping information

Conversion obtains, and the initial index of RB of the frequency hopping between time slot 0 and the time slot 1

Then by the initial index (n of the RB of time slot 0 _PRB ^S1(i)) conversion obtains, and being formulated then can be following:

$n_{\mathrm{PRB}}^{S1}\left(i\right)={\mathrm{RB}}_{\mathrm{START}}$

${\tilde{n}}_{\mathrm{PRB}}^{S1}\left(i\right)=n_{\mathrm{PRB}}^{S1}\left(i\right)-{\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}/2$

$n_{\mathrm{PRB}}\left(i\right)={\tilde{n}}_{\mathrm{PRB}}\left(i\right)+{\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}/2$

What need explanation is, " Type 2 PUSCH Hopping " expression type 2 frequency hoppings in the table one, owing in each embodiment of the present invention, do not relate to the content aspect this, thus do not describe at this, specifically can be referring to prior art.

206, eNodeB issues ascending resource and gives signaling to the terminal.

Wherein, this ascending resource is given and is carried ascending resource assignment information and frequency hopping information in the signaling; In addition, give in the signaling flag bit that can frequency hopping identifies (Hopping Flag) at this ascending resource and be set to 1, need carry out ascending frequency-hopping with indicating terminal.

207, resolve broadcast and ascending resource and give signaling.

The terminal receives the broadcast that eNodeB issues, and through resolving this broadcast, knows current area support Synthesized Frequency Hopping pattern; In addition; The terminal also receives the ascending resource that eNodeB issues and gives signaling, gives signaling through resolving this ascending resource, and the frequency hopping type of knowing current support is a Class1; Meanwhile, give signaling through the parsing ascending resource and can also know ascending resource assignment information and frequency hopping information.

208, the Class1 frequency hopping mode of Synthesized Frequency Hopping pattern is adopted at the terminal, distributes at eNodeB according to ascending resource assignment information and frequency hopping information on the bandwidth of PUSCH channel and sends upstream data, and concrete sending method can repeat no more at this referring to prior art.

It is understandable that in the present embodiment, the bandwidth of distribution can RB be a unit.

By on can know; Present embodiment adopts poor with ascending resource total bandwidth and the bandwidth of keeping for the PUCCH channel, and perhaps poor with ascending resource total bandwidth and the shared bandwidth of PUCCH channel reality is as the bandwidth of distributing to the PUSCH channel; Make the idle bandwidth of PUCCH channel; Be that idle RB can fully be used, for example, the ascending resource total bandwidth $N_{\mathrm{RB}}^{\mathrm{UL}}=25,$ The actual shared bandwidth of PUCCH channel $N_{\mathrm{RB}}^{\mathrm{HO}}=5,$ Then keep for the bandwidth of PUCCH channel ${\tilde{N}}_{\mathrm{RB}}^{\mathrm{HO}}=6,$ $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=19,$ Perhaps can obtain $N_{\mathrm{RB}}^{\mathrm{PUSCH}}=20,$ It is thus clear that except the bandwidth or the actual shared bandwidth of PUCCH channel of keeping for the PUCCH channel, remaining bandwidth all can be distributed to the PUSCH channel, thereby has improved the utilance of frequency hopping gain and band resource, and has simplified N _RB ^PUSCHAccount form, reduced the complexity of system.
