Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink power control method, system, and terminal.
Background
LTE (Long Term Evolution) is an Evolution of Universal Mobile Telecommunications System (UMTS) technology dominated by 3rd generation partnership Project (3 GPP), commonly referred to as 3.9G, and is considered the mainstream technology for Evolution from 3G to 4G. The LTE system not only improves the performance of cell-edge users, but also increases cell capacity and reduces system delay, and has technical advantages of high signal rate, packet transfer, delay reduction, wide area coverage, downward compatibility, and the like, compared to 3G.
LTE-a (LTE-Advanced) is a subsequent evolution of LTE technology, LTE systems do not support concurrent configuration of PUSCH (Physical Uplink Shared Channel) and PUCCH (Physical Uplink control Channel), compared to LTE systems, LTE-a Uplink supports Carrier Aggregation (CA) technology, where PUSCH and PUCCH are configured concurrently.
In a scenario where PUSCH and PUCCH are configured to be concurrent, according to the specification in standard 3GPP TS36.213, when PUSCH and PUCCH are configured to be concurrent on serving cell c, PUCCH transmit power of subframe i on the serving cell is defined as:
in this formula:
PCMAX,c=min{PEMAX,c,PUMAX,c}，PEMAX,cis the maximum allowed power, P, of the higher layer configured serving cell cUMAX,cThe maximum supporting transmission power of the UE is determined according to the power level of the UE (user equipment) and the number of the sending frequency band;
PO_PUCCHis a cell-specific parameter PO_NOMINAL_PUCCHAnd UE specific component PO_UE_PUCCHThe sum value of (a) represents;
PLcrepresents the downlink path loss, which can be calculated by the UE;
h(nCQI,nHARQ,nSR) Is determined by the PUCCH formatSection 5.1.2.1 of the standard 3GPP TS36.213 specifies h (n) corresponding to different PUCCH formatsCQI,nHARQ,nSR) A value;
ΔF_PUCCH(F) corresponding to Delta in PUSCH power controlTF(i) Parameters for controlling the received signal-to-interference-and-noise ratio of each PUCCH format, provided by the higher layer;
when the UE is configured by the high layer to transmit PUCCH at two antenna ports, delta isTxD(F') is provided by a higher layer; otherwise, ΔTxD(F')=0；
g (i) represents the current PUCCH channel power control adjustment state, which is used for the base station to control the PUCCH transmission power of the UE in a closed loop mode.
The PUSCH transmission power of subframe i on the serving cell c is defined as:
in this formula:
MPUSCH,c(i) indicating the number of resource blocks allocated by the serving cell c based on the uplink grant;
PO_PUSCH,c(j) is a semi-statically set power reference value which can be used for setting different values for different uplink transmission signal packets, and is defined by a cell-specific parameter PO_NOMINAL_PUSCH,c(j) And UE specific component PO_UE_PUSCH,c(j) The sum value of (a) represents;
αc(j) the amount of compensation for the path loss (path loss compensation factor) is indicated by higher layer signaling.
ΔTF,c(i) Is an offset corresponding to the code rate and modulation scheme;
fc(i) is a Power increment, which is mainly related to TPC (Transmit Power Control) commands.
In addition, for a UE supporting CA, when the total power of a plurality of serving cells exceeds the maximum transmitting power of the UEWhen the power back-off process is needed. The principle of power backoff is: on the premise of ensuring that the power of the PUCCH or the PUSCH mapped with the UCI is not changed, the power of the PUSCH without mapped UCI (Uplink Control Information) is reduced, so that the total power of a plurality of service cells is reduced.
As can be seen from the above description, the PUSCH and PUCCH transmit powers defined by the standard are different.
Since the baseband signal processing procedures of the PUSCH and the PUCCH are not completely the same, the power impact of the fixed-point implementation on the PUSCH and the PUCCH is also not completely the same, that is, the compensation of the power loss introduced by the fixed-point implementation in the baseband processing procedures is also different for the PUSCH and the PUCCH.
Because the power calculation of the PUSCH and the PUCCH and the influence of the baseband processing are independent, in a scenario where the PUSCH and the PUCCH are concurrent, the prior art adopts a parallel power control method, as shown in fig. 1, the processing method may include the following steps:
s1, generating PUSCH and PUCCH baseband signals respectively;
s2, respectively calculating a baseband power control adjustment value and a radio frequency power control adjustment value of the PUSCH and the PUCCH;
s3, performing baseband power control adjustment on the PUSCH baseband signal by using the calculated baseband power control adjustment value of the PUSCH, and performing baseband power control adjustment on the PUCCH baseband signal by using the calculated baseband power control adjustment value of the PUCCH;
and S4, performing radio frequency power control adjustment on the PUSCH baseband signal processed in the step S3 by using the radio frequency power control adjustment value of the PUSCH obtained through calculation, and performing radio frequency power control adjustment on the PUCCH baseband signal processed in the step S3 by using the baseband power control adjustment value of the PUCCH obtained through calculation.
In fig. 1, DMRS is a DeModulation Reference Signal (DeModulation Reference Signal), and SRS is a Sounding Reference Signal (Sounding Reference Signal).
Although the parallel power control method adopted in the prior art can realize power control when the PUSCH and the PUCCH are concurrent, the prior art needs a parallel baseband signal processing flow and a power control processing flow (including baseband power control and radio frequency power control), so that the complexity of realization is extremely high, and the application in an actual system is greatly limited.
