Embodiment
The embodiment of the invention is according to maximum transmission power and report the uplink gross power of the subframe of PHR to calculate PH, like this, no matter having what member carriers to participate in upstream data sends, all have to a PH, thereby only report a PHR, realized reporting uplink power margin information under the situation of carrier aggregation.
Referring to Fig. 1, the main method flow process of reporting uplink power margin information is as follows in the present embodiment:
Step 101:UE obtains the maximum transmission power of self and reports the uplink gross power of the subframe of PHR.
Step 102:UE calculates PH according to maximum transmission power and the uplink gross power that reports the subframe of PHR.That is PH=P,
Max-∑ P
CC(reporting the uplink gross power of the subframe of PHR).
Step 103:UE reports the PHR that comprises PH.
Wherein, the form that UE reports PHR to adopt comprises MAC (medium access control) head and MACCE (Control Element, control unit).MAC as shown in Figure 2, and MAC CE as shown in Figure 3.LCID (Logical Channel ID) in the MAC head is used to identify the logical channel number of corresponding load part, reports for PHR, and LCID is used to identify corresponding load and partly is PHR.E represents extended bit, and being used to indicate next byte is MAC head or MAC load.R represents reserved bit.PH represents uplink power margin.MAC CE also can not comprise reserved bit R, perhaps increases or reduce the quantity of reserved bit R as required, and Fig. 3 only provides an example.
UE just reports PHR after the triggering that is subjected to trigger condition.Trigger condition has multiple, as comprising one of following condition at least:
Have ascending resource to use, forbid that PHR timer (prohibitPHR-Timer) is overtime, and the path loss that the difference between current PHR subframe path loss and the last subframe path loss that reports PHR surpasses configuration changes thresholding (dl-PathlossChange);
It is overtime that the PHR cycle is triggered timer (periodicPHR-Timer);
Dispose PHR for the first time or PHR is carried out reprovision.
Wherein, prohibitPHR-Timer, periodicPHR-Timer and dl-PathlossChange are pre-configured.The base station can send to UE with these three parameters by RRC (Radio Resource control) signaling, so that UE carries out relevant configuration.The base station is dl-PathlossChange of each member carrier configuration, and the dl-PathlossChange of different members carrier wave configuration can be the same or different.Perhaps, the base station is that UE only disposes a dl-PathlossChange.Because the path loss between the discontinuous member carrier may differ greatly, institute thinks that the different members carrier wave disposes different dl-PathlossChange, and this scheme is applicable to the scene of discontinuous member carrier.For the identical dl-PathlossChange of all member carriers configuration or be that a UE only disposes a dl-PathlossChange, this scheme is applicable to the scene of continuous member carrier.
Path loss is all arranged on each member carrier, and the circuit loss value on each member carrier may be different.So so many circuit loss value, how carrying out the path loss variation relatively is following problem to be solved.Circuit loss value of giving the correct time on the last PHR and current circuit loss value all are one of following:
The mean value of the path loss of all member carriers; That is average value P L,
Ave=(PL
1+ ... PL
N)/N, PL
NThe path loss of representing N member carrier.
The smooth value of the path loss of all member carriers; That is, since the 2nd member carrier, successively according to formula PL
Ave_N=PL
Ave_N-1+ (1-p) PL
NObtain the smooth value of each member carrier, then with the smooth value of last member carrier smooth value as the path loss of all member carriers.Wherein p is a smoothing factor, can be by RRC parameter configuration or fixing in agreement, PL
Ave_NIt is the smooth value of N member carrier.
The maximum of path loss in all member carriers;
The minimum value of path loss in all member carriers;
The circuit loss value of mandatory member's carrier wave;
The circuit loss value of the member carrier that resource utilization is the highest;
The circuit loss value of the member carrier of current monitoring physics Dedicated Control Channel (PDCCH).
Adopt the mean value or the smooth value of path loss, can consider the path loss situation of all member carriers, and comprehensively these factors obtain the circuit loss value of an equilibrium, it is more comprehensive that this mode is considered.Adopting the maximum or the minimum value of path loss, is that the peak value (or extreme value) according to path loss compares.Represent the circuit loss value of all member carriers to participate in relatively by the peak value that outstanding role is arranged, under the result's who is applicable to practical application situation, determine that from the path loss of a plurality of member carriers the scheme ratio of a path loss is easier to realize.Adopt the circuit loss value of the member carrier of appointment, that resource utilization is the highest or current monitoring PDCCH to participate in relatively, be to consider to be responsible for main business or to carry the member carrier of more data volume, consider from operational angle, this member carrier is being brought into play main effect, so the variable quantity of the circuit loss value of this member carrier surpasses dl-PathlossChange dB, just thinks to satisfy condition.
In a word, can determine from the path loss of a plurality of member carriers that a path loss participates in scheme relatively, all be suitable for present embodiment.
More than each that reports PHR realized that details all done detailed introduction, further understand the relation of each step below by an embodiment.
Referring to Fig. 4, the detailed method flow process of reporting uplink power margin information is as follows in the present embodiment:
The base station sends to UE by the RRC signaling with PHR parameters such as prohibitPHR-Timer, periodicPHR-Timer and dl-PathlossChange, and UE carries out relevant configuration according to the information of receiving.
Step 401:UE obtains the maximum transmission power of self and reports the uplink gross power of the subframe of PHR.
Step 402:UE is according to maximum transmission power and report the uplink gross power of the subframe of PHR to calculate PH.
Step 403:UE finds to have satisfied trigger condition.As long as there is an aforesaid trigger condition to satisfy.
Step 404:UE sends PHR on first can hold the uplink transmission resource of PHR.Report form referring to Fig. 2 and shown in Figure 3.
Step 405:UE starts or restarts prohibitPHR-Timer, periodicPHR-Timer.
Wherein, step 401 and 402 is two independently processes with respect to step 403, after the strict execution of nothing is lost.
