Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
Adopt the method for ascending power compression of the present invention, can solve under the up-link carrier aggregation scene problem of UE power limited.And, again PUCCH is carried out power compression owing to when power compression, consider earlier PUSCH is compressed if needed.Like this, as much as possible little to the influence of the PUCCH of up feedback control information, because the PUCCH carrying is uplink feedback information about downlink data transmission, so reduced influence to the full extent to downlink data transmission; When PUSCH is carried out power compression, considered the difference of different PUSCH simultaneously, carried out power compression in various degree, so also guaranteed transmission of uplink data to the full extent.
The method of ascending power compression provided by the invention specifically comprises: if adopt plural up channel transmission information simultaneously, then in each up channel power demand sum during greater than the maximum transmission power of subscriber equipment, part or all of up channel is carried out power compression, power sum after each up channel compression is not more than the maximum transmission power of subscriber equipment, and described part or all of up channel adopts the power after the compression to carry out message transmission respectively.
Wherein, the plural up channel of Cai Yonging can all be PUSCH or all be PUCCH simultaneously, also can not only comprise PUSCH but also comprise PUCCH.
When part or all of up channel is carried out power compression, the descending order or the descending order of power demand of transmission block that can take according to ascending order of detection reference signal SRS or up channel, perhaps according to the resulting order of combination of two above factors in the size of the size of the size of SRS, transmission block, power demand, up channel is carried out power compression in a certain order, certainly for different up channels, can carry out power compression according to different ratios; Be the power of the intact up channel of every compression, just judge whether the power sum after each up channel compresses is not more than the maximum transmission power of subscriber equipment, if, according to the power of the next up channel of described sequential compression, the power sum after each up channel compression is not more than the maximum transmission power of subscriber equipment.
Perhaps when part or all of up channel is carried out power compression, according to predetermined ratio whole up channels of same type are carried out power compression, for example all PUSCH are carried out power compression according to predetermined ratio, perhaps all PUCCH are carried out power compression according to predetermined ratio.Wherein, can adopt identical ratio to carry out power compression, also can adopt different ratios to carry out power compression different up channels.
Wherein, the present invention can also stop to adopt part up channel transmission information wherein, perhaps circularly up channel is carried out power compression, for example: the up channel to current transmission information carries out power compression, power sum after the whole up channels compression of current transmission information is during greater than the maximum transmission power of subscriber equipment, stop to adopt part up channel transmission information wherein, in whole up channel power demand sums of residue transmission information during greater than the maximum transmission power of subscriber equipment, return the step of the up channel of current transmission information being carried out power compression, when whole up channel power demand sums of residue transmission information were not more than the maximum transmission power of subscriber equipment, whole up channels of residue transmission information adopted required separately power to carry out message transmission respectively; When the power sum after whole up channel compressions of current transmission information was not more than the maximum transmission power that is used for equipment, whole up channels of current transmission information adopted the power after the compression separately to carry out message transmission respectively.
