Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to a Long Term Evolution Advanced (LTE-Advanced) technology, and in particular to an uplink channel processing method, terminal, Evolved Node B (eNB), system and computer storage medium for dual-link multicarrier transmission in LTE-Advanced. 
       BACKGROUND 
       [0002]    In LTE, uplink channels of a terminal include a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH) and a Physical Random Access Channel (PRACH). 
         [0003]    Data information, a Scheduling Request (SR), a Hybrid Automatic Repeat Request (HARQ) and Channel State Information (CSI) may be transmitted via a PUSCH, and the SR, the HARQ and the CSI may be transmitted via a PUCCH. A PRACH is mainly configured for uplink access of a terminal, including random access implemented by transmitting a preamble on a configured time/frequency resource. An eNB is required to transmit Message 2 (Msg2) for responding to random access to the terminal when receiving the preamble transmitted by the terminal. In case of non-competition-based random access of the terminal, the terminal determines that random access succeeds when receiving Msg2. In case of competition-based random access, the terminal is further required to transmit Msg3 for resolving a random access conflict after receiving Msg2. The eNB is required to send Msg4 for containing an access competition resolving identifier to the terminal after receiving Msg3 transmitted by the terminal. And when the competition resolving identifier in Msg4 received by the terminal from the eNB is consistent with a competition resolving identifier in Msg3, the terminal determines that competition resolution succeeds. 
         [0004]    In a scenario of a Carrier Aggregation (CA) in a related technology, if a plurality of component carriers are aggregated for performing transmission, a process of simultaneously transmitting a random access channel and a PUCCH on a plurality of carriers may not occur, because the random access channel is transmitted only on a Primary Cell (Pcell) and the PUCCH is also transmitted only on the Pcell. In case of simultaneous transmitting of PUSCHs of the plurality of carriers, if a sum of power of the plurality of PUSCHs exceeds a maximum power value supported by a terminal due to limitation on power of the terminal, it is necessary to optionally guarantee power of the PUSCH with Uplink Control Information (UCI), and then power is equally allocated to the other PUSCHs without any UCI. During simultaneous transmission of the PUCCH and the PUSCHs, if a sum of power of the PUCCH and one or more PUSCHs exceeds the maximum power value supported by the terminal due to limitation on the power of the terminal, it is necessary to sequentially guarantee power of the PUCCH and the power of the PUSCH with the UCI, and then power is equally allocated to the other PUSCHs without any UCI. 
         [0005]    Since backhauls are absorbed to timely share scheduling information and power allocation information among a plurality of carriers in a CA scenario, the plurality of carriers may cooperate with each other to avoid power exceeding maximum power of a terminal. When the power exceeds the maximum power of the terminal, a plurality of carrier machines corresponding to the plurality of carriers may predict and calculate corresponding adjusted values of the terminal for the respective carriers and channels. 
         [0006]    Introduction of a dual-link technology is considered in Stage Release 12 (R12). The main difference between the dual-link technology and CA is that two eNBs involved in a dual link adopt a non-ideal backhaul connection That is, an independent scheduling manner is adopted for the two eNBs. With introduction of independent scheduling, two carriers cannot dynamically share uplink scheduling information and corresponding power control information. In such case, if the two carriers are independently configured with maximum power values, uplink power may be limited and wasted. In case of no independent limitation, a sum of power for the terminal to transmit channels corresponding to the two eNBs may exceed a maximum power value supported by the terminal. 
         [0007]    With respect to the problem of how to effectively process power for performing transmission via a plurality of channels by a terminal in a dual-link scenario, there is yet no an effective solution in the related technology.

       Embodiment 1 
       [0069]    The embodiment provides an uplink channel processing method. As shown in  FIG. 1 , the method includes the following steps. 
         [0070]    In Step  101 , before simultaneously performing transmission via at least two uplink channels at a preset moment, a terminal detects whether a sum of power of the uplink channels exceeds maximum power supported by the terminal or not. The process proceeds to Step  102  and Step  103 , if the sum of power of the uplink channels exceeds the maximum power supported by the terminal, otherwise, the process proceeds to Step  104 . 
         [0071]    Simultaneously performing transmission via the at least two uplink channels at the preset moment means that the at least two uplink channels partly overlapped with each other at a preset observation moment. 
         [0072]    In Step  102 , priorities of the uplink channels are determined according to information on the uplink channels.

         [0076]    amounts of information represented by the uplink channels, 
         [0077]    number of types of the uplink channels, 
         [0078]    indexes of serving cells represented by the uplink channels, and

       Embodiment 5 
       [0246]    The embodiment provides an uplink channel processing system. As shown in  FIG. 5 , the system includes a terminal  51  and an eNB  52 . The terminal  51  is structured as shown in  FIG. 3  and the eNB  52  is structured as shown in  FIG. 4 , which will not be elaborated in the embodiment. 
       Embodiment 6 
       [0247]    The embodiment provides a computer storage medium having stored therein computer-executable instructions for executing an uplink channel processing method shown in  FIG. 1 or 2 . 
         [0248]    Detailed descriptions will be further made below with reference to a dual-link scenario. 
         [0249]    In a dual-link scenario, there exist at least two eNBs, which are called a Master eNB (MeNB) and a Secondary eNB (SeNB) respectively. The MeNB is a master serving eNB, the SeNB is a non-master serving eNB (or called a secondary serving eNB). The MeNB may be responsible for transmitting some system messages and some high-layer configuration signalling of the SeNB to a terminal. The MeNB and the SeNB may implement independent scheduling of Media Access Control (MAC) layer. 
         [0250]    A plurality of serving cells (carriers) may be configured under the MeNB. One of the plurality of serving cells is a Pcell of the MeNB, called MPcell. PUCCHs of all the serving cells under the MeNB are only transmitted through the carrier corresponding to MPcell. Moreover, the terminal only detects system information and paging messages of the MeNB on MPcell. 
         [0251]    A plurality of serving cells (carriers) may be configured under the SeNB. One of the plurality of serving cells is a Pcell of the SeNB, called SPcell. PUCCHs of all the serving cells under the SeNB are only transmitted through the carrier corresponding to SPcell. Moreover, the terminal only detects uplink random access response information (i.e. Msg2) corresponding to different Timing Alignment Group (TAG) cells (carriers) in the SeNB on SPcell. 
         [0252]    Optionally, the PUCCHs of the serving cells under the SeNB may be transmitted through the carrier of the MPcell. 
         [0253]    The serving cells in the MeNB may be grouped into a CG, called MCG, and the serving cells in the SeNB may be grouped into a CG, called SCG 
       Embodiment 7 
       [0254]    It is assumed that there exist two dual-link eNBs, i.e. MeNB and SeNB, and a dual-link terminal, and the terminal establishes a dual link on the MeNB and the SeNB. When PRACHs transmitted to the two eNBs by the terminal temporally overlap, the terminal is required to determine priorities of the PRACHs for the two eNBs. 
         [0255]    The determination is made according to different PRACH formats: the PRACHs have different preamble formats, and the PRACH with a longest preamble format duration has a highest priority. In the two transmitted PRACHs, the PRACH with the longest preamble format duration covers most subframes, and subframes covered by the PRACH with a shortest preamble format duration may not correspond to the subframes covered by the PRACH with the longest preamble format duration one to one, so that the priority of the PRACH with a longer preamble format duration is accordingly higher. 
       Embodiment 8 
       [0256]    It is assumed that there exist two dual-link eNBs, i.e. MeNB and SeNB, and a dual-link terminal, and the terminal establishes a dual link on the MeNB and the SeNB. When PRACHs transmitted to the two eNBs by the terminal temporally overlap, the terminal is required to determine priorities of the PRACHs for the two eNBs. 
         [0257]    The priorities are determined according to a sequence of transmission time of different PRACHs: the PRACHs may be transmitted at different time, and the PRACH of which the transmission time is earlier (which is transmitted earlier, or of which the transmission time is earlier, or which is transmitted at previous time) has a highest priority. 
       Embodiment 9 
       [0258]    It is assumed that there exist two dual-link eNBs, i.e. MeNB and SeNB, and a dual-link terminal, and the terminal establishes a dual link on the MeNB and the SeNB. When preambles transmitted to the two eNBs by the terminal temporally overlap, the terminal is required to determine priorities of PRACHs for the two eNBs. 
         [0259]    Determination is made according to different PRACH completion manners. The preambles may be divided into: preamble transmitted based on non-competition and preamble transmitted based on competition. Preamble transmitted based on non-competition has a priority higher than that of preamble transmitted based on competition. Such a design may ensure timeliness of random access and ensure selectivity of time-domain transmission resources.
