A kind of band configurations method and system provided by the present invention, by base station (bs) setting db-dc-hsdpa configuration mould Formula, the upstream band in described db-dc-hsdpa configuration mode is xxv or iv, downstream bands are xxv and iv；Bs by arrange Db-dc-hsdpa configuration mode is sent to user equipment (ue) by descending control signaling；Ue is according to db- in descending control signaling The band configurations of dc-hsdpa configuration mode, carry out up transmitting.
By means of the invention it is possible to support in the block g frequency range of e1900 frequency range using db-dc-hsdpa.In addition, this Invention uses control signaling form, can compatible Long Term Evolution (lte) system uplink mission need, and disclosure satisfy that senior long-term Evolution (lte-a) system uplink launch requirements；Descending control signaling expense can be reduced, thus effectively improving system throughput.
Brief description
Fig. 1 is a kind of flow chart of present invention band configurations method；
Fig. 2 is a kind of composition structural representation of present invention band configurations system.
Specific embodiment
The technical solution of the present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
For supporting in the block g frequency range of e1900 frequency range using db-dc-hsdpa, a kind of frequency provided by the present invention Band collocation method, in the present invention, the configuration mode of setting is referred to as configuring 4 patterns, as shown in figure 1, mainly comprising the steps that
Step 101, bs setting db-dc-hsdpa configures 4 patterns.
The db-dc-hsdpa configuration of increased configuration 4 pattern is as shown in table 2 below:
Db-dc-hsdpa configures Upstream band Downstream bands
1 i or viii i and viii
2 ii or iv ii and iv
3 i or v i and v
