Embodiment

Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.

Fig. 1 for the embodiment of the present invention one provide across carrier downlink control channel indicating method flow chart, as shown in Figure 1, its concrete steps are as follows:

Step 101: evolution base station (eNB, Evolution Node Base) according to the frequency of each carrier wave in LTE-A system, according to preset numbers allocation rule, for unique numbering of allocation of carriers of each frequency, this allocation rule is broadcast to all subscriber equipmenies (UE, User Equipment) in system.

Preset numbers allocation rule can be pre-configured on eNB, can be also that eNB and all UE make an appointment.

The numbering of carrier wave can adopt N (N is nonnegative integer) bit-binary digital watch to show.

wherein, for the operator that rounds up, M is the frequency number of all carrier waves in LTE-A system.

Numbering allocation rule can be as follows:

Rule one, according to frequency from small to large or from big to small, by the carrier index of each frequency be successively 0,1,2,3 ....

Rule two, determine and will in step 102, be broadcast to the order of each frequency of UE according to eNB, by the carrier index of each frequency be successively 0,1,2,3 ..., for example: if having frequency a, b, c, d, eNB determines that the order that each frequency is broadcast to UE in step 102 is b, c, a, d, and the numbering of the carrier wave of frequency b, c, a, d is respectively 0,1,2,3.

Step 102:eNB is to the frequency of all carrier waves in all UE broadcast systems in system.

In this step, eNB can be broadcast to UE by the frequency of all carrier waves in system by system message, and system message can be carried in Radio Resource control (RRC, Radio Resource Control) signaling.

If adopt numbering allocation rule one, eNB can not consider the broadcast order of frequency; If adopt numbering allocation rule two, eNB need to, determining after the broadcast order of each frequency, record the frequency of each carrier wave and the corresponding relation of numbering, using as the follow-up foundation that issues descending control signaling.

Step 103:UE receives and records the frequency of all carrier waves in the system that eNB sends.

Step 104:eNB will transmit the descending control signaling for carrier wave A to UE1 on carrier wave B, puts into the numbering of carrier wave A in this descending control signaling, and this descending control signaling is carried on carrier wave B and sends to UE1.

Step 105:UE1 receives this descending control signaling, from signaling, read the numbering of carrier wave A, according to the frequency of all carrier waves in the system of record in numbering allocation rule and step 103, determine the frequency of carrier wave A, on carrier wave A corresponding to this frequency, carry out the content in this descending control signaling.

In actual applications, if numbering allocation rule is to be configured on eNB by administrative staff in advance, in step 101, eNB also can not be broadcast to this allocation rule all UE in system, but in step 102, this allocation rule is broadcast to all UE together with the frequency of all carrier waves in system, or, directly in step 102, the corresponding relation of the frequency of each carrier wave and numbering is broadcast to all UE.

If eNB is broadcast to all UE by the corresponding relation of the frequency of each carrier wave and numbering in step 102, UE need to record the frequency of each carrier wave and the corresponding relation of numbering, and in step 105, UE1 can directly find the frequency of carrier wave A according to this corresponding relation.

Fig. 2 for the embodiment of the present invention two provide across carrier downlink control channel indicating method flow chart, as shown in Figure 2, its concrete steps are as follows:

Step 201: for the UE of each employing polymerization carrier wave in LTE-A system, eNB concentrates the frequency of each carrier wave according to the polymerization carrier wave of this UE, according to the carrier index allocation rule of this default UE, for unique numbering of allocation of carriers of the concentrated each frequency of the polymerization carrier wave of this UE, the carrier index allocation rule of this UE is sent to this UE.

The default carrier index allocation rule of each UE can be pre-configured on eNB, can be also that eNB appoints with each UE respectively.

The carrier index allocation rule of each UE can be identical, also can be different.

Equally, the numbering of the carrier wave of each UE can adopt N (N is nonnegative integer) bit-binary digital watch to show.

wherein, for the operator that rounds up, the frequency number of the concentrated carrier wave of polymerization carrier wave that M is UE.

Numbering allocation rule can be as follows:

Rule one, according to the frequency of the concentrated carrier wave of the polymerization carrier wave of UE from small to large or from big to small, by the carrier index of each frequency be successively 0,1,2,3 ....

Rule two, determine and will in step 202, send to the order of each frequency of this UE according to eNB, by the carrier index of each frequency be successively 0,1,2,3 ....For example: if the frequency of the concentrated carrier wave of the polymerization carrier wave of UE is a, b, c, d, eNB determines that the frequency of each carrier wave being sent to the order of UE in step 202 is b, c, a, d, and the numbering of the carrier wave of frequency b, c, a, d is respectively 0,1,2,3.

Step 202: for each UE, eNB sends the frequency of the concentrated carrier wave of the polymerization carrier wave of this UE to this UE.

In this step, eNB can, by common signaling as system message, also can send to UE by the frequency of carrier wave by dedicated control signaling, and common signaling or dedicated control signaling can be carried in RRC signaling.

Step 203:UE receives and the frequency of the carrier wave that the polymerization carrier wave of minute book UE is concentrated.

Step 204:eNB will transmit the descending control signaling for carrier wave A to UE1 on carrier wave B, puts into the numbering of carrier wave A in this descending control signaling, and this descending control signaling is carried on carrier wave B and sends to UE1.

Step 205:UE1 receives this descending control signaling, from this signaling, read the numbering of carrier wave A, according to the frequency of the concentrated carrier wave of the polymerization carrier wave of the UE1 of record in numbering allocation rule and step 203, determine the frequency of carrier wave A, on carrier wave A corresponding to this frequency, carry out the content in this descending control signaling.

Equally, in actual applications, if the carrier index allocation rule of each UE is to be configured on eNB by administrative staff in advance, in step 201, eNB also can not send to corresponding UE by the carrier index allocation rule of each UE, but in step 202, the allocation rule of each UE is sent to corresponding UE together with the frequency of the concentrated carrier wave of the polymerization carrier wave of this UE, or, directly in step 202, the corresponding relation of the frequency of carrier wave concentrated the polymerization carrier wave of each UE and numbering is sent to corresponding UE.

If eNB sends to corresponding UE by the carrier index allocation rule of each UE together with the frequency of the concentrated carrier wave of the polymerization carrier wave of this UE in step 202, each UE needs the concentrated frequency of carrier wave and the corresponding relation of numbering of polymerization carrier wave of minute book UE, and, in step 205, UE1 can directly find the frequency of carrier wave A according to this corresponding relation.

In Fig. 1,2 illustrated embodiments, to be allocation of carriers numbering according to the frequency of carrier wave, in actual applications, also can be according to the physical channel mark (PCI of carrier wave, Physical Channel Identifier) be allocation of carriers numbering, now, " frequency " in Fig. 1,2 illustrated embodiments all need to be replaced with to " PCI ", simultaneously, " UE1 reads the numbering of carrier wave A from this signaling " in step 105 afterwards, UE1 need to be synchronizeed with the carrier wave in system, to obtain the PCI of each carrier wave; " UE 1 reads the numbering of carrier wave A from this signaling " in step 205 afterwards, the carrier wave that UE1 need to be concentrated with the polymerization carrier wave of UE1 is synchronizeed, to obtain the PCI of each carrier wave.
