Technical Field

The present invention relates to a power control technology of a mobile communication system, and in particular, to a power setting method of a physical uplink control channel of a Long Term Evolution (LTE) system and a user equipment.

Background

In The third generation partnership project (3 GPP), The3rd generation partnership project (3 GPP) LTE system, uplink power control (uplink power control, abbreviated as uplink power control) is used to control The transmission power of an uplink physical channel (uplink physical channel) to compensate for The path loss and shadow fading of The channel and suppress inter-cell interference. The uplink physical channel controlled by the uplink power control includes a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and a Sounding Reference Signal (SRS). The uplink power control of the LTE system adopts a control mode combining open loop (openloop) and closed loop (closed loop).

In the LTE system, the transmit power of a physical uplink control channel PUCCH of a User Equipment (UE) in an ith subframe (subframe) (abbreviated as subframe i) is defined by the following equation (1) (unit is dBm):

P_PUCCH(i)＝min{P_CMAX，P_{O_PUCCH}+PL+h(n_CQI，n_HARQ)+Δ_{F_PUCCH}(F)+g(i)}(1)

in the above formula, each parameter represents:

(1)P_CMAXthe value range of the maximum configured output power (the configurable maximum power output power) of the UE, which is set by the UE, is determined by a plurality of parameters, and includes: a maximum UE power (the maximum UE power) determined by the UE power class (the UE power class), a maximum configured power (IEP-Max) of the system configuration, a maximum configured output power deviation (P)_CMAXtolerance), Maximum Power Reduction (MPR), and additional maximum power reduction (a-MPR).

(2)P_{O_PUCCH}Is an open loop power control parameter, is a cell specific (cell specific) quantity P_{O_NOMINAL_PUCCH}And a UE specific (UEspecific) quantity P_{O_UE_PUCCH}The sum of (1).

(4)Δ_FPUCCH(F) the LTE system defines 6 PUCCH formats, namely PUCCHformat1/1a/1b/2/2a/2 b.

in the formula, for a Frequency Division Duplex (FDD) system, M is 1, k₀4. That is, for FDD system, the power control adjustment state (i.e. current power control adjustment state) g (i) of PUCCH in sub-frame i is the power control adjustment state g (i-1) in sub-frame i-1 and the transmission power control command (TPCcomp) indicated by the base station in sub-frame i-4_PUCCHThe cumulative value of (c).

Time Division Duplex (TDD) system, M and k_mThe value of (a) is related to the Uplink-downlink configurations (Uplink-downlink configurations). That is, for TDD systems, the power control adjustment state (i.e., the current power control adjustment state) g (i) of PUCCH in subframe i is the power control adjustment state g (i-1) in subframe i-1 and subframe i-k₀，i-k₁，...，i-k_M-1Multiple transmit power control commands indicated by upper base station_PUCCHThe cumulative value of the sum of (a).

For the TDD system, if subframe i is not one uplink subframe, g (i) is g (i-1).

Transmitting power control commands_PUCCHIs a UE-specific (UE specific) closed loop correction value, which is sent by the base station to the target UE through a Physical Downlink Control Channel (PDCCH).

If the UE does not detect TPCcomp on a subframe, the UE determines whether the TPCcomp is detected_PUCCH＝0dB。

The PUCCH is used to carry Uplink Control Information (UCI), and includes Scheduling Request (SR), acknowledgement/negative acknowledgement (ACK/NACK) of hybrid automatic repeat request HARQ of Physical Downlink Shared Channel (PDSCH), and downlink Channel State Information (CSI) fed back by the UE. Wherein, the CSI comprises three forms: channel Quality Indication (CQI), Precoding Matrix Indication (PMI), and Rank Indication (RI).

An LTE-Advanced system (LTE-a system for short) is a next-generation evolution system of the LTE system.

As shown in fig. 1, an LTE-a system adopts a carrier aggregation (carrier aggregation) technique to extend a transmission bandwidth, where each aggregated carrier is referred to as a "component carrier" (CC), also called a "cell". The plurality of component carriers may be contiguous or non-contiguous; the two frequency bands may be located in the same frequency band (operating band) or in different frequency bands.

The prior art proposes that in LTE-a systems, a user equipment may receive multiple PDSCHs simultaneously on multiple configured or activated component carriers. Acknowledgement information ACK/NACK of multiple PDSCHs is transmitted on one UE specific (UE specific) component carrier through one PUCCH. The UE-specific component carrier is called a Primary Component Carrier (PCC), also known as primary cell (Pcell).

For LTE-A system, P in formula (1)_CMAX，cIs the maximum transmit power (the configured UE transmitted power for the primary cell 1) configured on the primary cell (primary component carrier).

In order to carry acknowledgement information ACK/NACK of multiple PDSCHs, a new PUCCH format, called pucchformex 3 (also called a third PUCCH format), is introduced in the LTE-a system. Currently, an LTE-a system aggregates 5 component carriers at most, and if a UE needs to feed back ACK/NACK 1-2 bits for each PDSCH (each PDSCH can carry 1-2 Transport Blocks (TBs), and each transport block needs to feed back 1bit ACK/NACK), the ACK/NACK that the pucchfmat 3 needs to carry is 1-10 bits. In addition, if the scheduling request information SR of 1bit is included, the amount of information that the pucchfmat 3 needs to carry is 1-11 bits.

Whether the ue transmits uplink control information using the pucchfmat 3 is configured by a higher layer. Compared with the PUCCHformat1/1a/1b/2/2a/2b, the PUCCHformat3 has different information carrying amount, different coding modes and different channel structures and different channelization modes. For example, unlike pucchfmate 1/1a/1b/2/2a/2b, pucchfmate 3 performs transmission precoding (transformational) before generating a single carrier-frequency division multiple access (SC-FDMA) signal in the time domain, so that the SC-FDMA signal generated by pucchfmate 3 is also called a DFT-S-OFDM signal. The above necessarily results in different error rate performance of pucchfmat 3, thereby requiring different UE transmit power to PUCCH.

Therefore, when the ue uses the puccformat 3 to send the uplink control information, how to set the transmit power of the physical uplink control channel becomes a problem to be solved.

EXAMPLE III

In the LTE-a system, when a user equipment UE sends a physical uplink control channel PUCCH with a format of pucchfmat 3 on a subframe i, the transmit power is obtained and set by calculation according to formula (3), and the flow is as shown in fig. 2, where the difference between the two previous embodiments is in step 220 and step 230.

Step 220, calculating and obtaining the power reference quantity P by taking PUCCHF (PuCCHfomat 3) as PUCCH reference format_PUCCH，ref；

Step 230, determining power offset Δ P of PUCCHformat3 based on the power reference obtained by calculation_PUCCHH (n), i.e. a fixed offset Δ_{F_PUCCH}(F)＝0。

Wherein h (n) for PUCCHformat3 is a power variable offset related to the information quantity n of uplink control information carried by the PUCCHformat3, i.e., h (n) is a function of the information quantity n, and the UE can determine the value of h (n) by means of table lookup; alternatively, the UE calculates the value of h (n) according to the formula (4), the formula (5) or the formula (6), which is not described herein again.

In the above-described embodiment of the method,

the information quantity n of the uplink control information is the information bit number n of the hybrid automatic repeat request_HARQI.e. n ═ n_HARQOr n is the number n of information bits of the Channel Quality Indicator (CQI)_CQII.e. n ═ n_CQI。

Or, the quantity n of the uplink control information is the number n of bits of the hybrid automatic repeat request_HARQPlus scheduling request bit number n_SRI.e. n ═ n_HARQ+n_SR。

For example, when a UE currently uses puccformat 3 to send 4-bits ack/NACK and send a 1-bit scheduling request, the amount of information carried by the PUCCH is 4+ 1-5 bits.

For example, if a UE currently uses puccformat 3 to send 6 bitmascck/NACK, the amount of information carried by the PUCCH is 6 bits.

For an FDD system, if the UE sends uplink control information with the format of pucchfmat 3 on subframe i, the ACK/NACK response information of the hybrid automatic repeat request HARQ carried therein is the PDSCH received on subframe i-4 for the UE.

For the TDD system, if the UE sends the uplink control information with the format of PUCCHfomat 3 on the subframe i, the carried ACK/NACK response information of the hybrid automatic repeat request HARQ is carried on the subframe i-k of the UE₀，i-k₁，...，i-k_M-1An upper received PDSCH; wherein, { k₀，k₁，...，k_M-1K and M are determined by Uplink-downlink configurations (TDD) of the TDD system, as shown in table 5.

Wherein, the number of bits n of the hybrid automatic repeat request_HARQCalculated as follows:

<math> <mrow> <msub> <mi>n</mi> <mi>HARQ</mi> </msub> <mo>=</mo> <munder> <mi>Σ</mi> <mrow> <mi>c</mi> <mo>&Element;</mo> <mi>C</mi> </mrow> </munder> <msub> <mi>z</mi> <mi>c</mi> </msub> <mo>;</mo> <mo>-</mo> <mo>-</mo> <mo>-</mo> <mrow> <mo>(</mo> <mn>7</mn> <mo>)</mo> </mrow> </mrow> </math>

in the formula,

z_cthe maximum number of transport blocks which can be carried by the PDSCH sent by the UE on the component carrier c is determined by a downlink transmission mode of the component carrier, and the downlink transmission mode of the component carrier is configured by a higher layer; c is a configured component carrier set or an activated component carrier set of the UE.

TABLE 5

For example, if the downlink transmission mode of the component carrier is a single-antenna transmission mode, the maximum number of transport blocks z that can be carried by the PDSCH transmitted by the UE on the component carrier_c1 is ═ 1; if the downlink transmission mode of the component carrier is the multi-antenna transmission mode, the maximum number z of transmission blocks that can be borne by the PDSCH sent by the UE on the component carrier_c＝2。

For example, in an FDD system, a certain UE currently configures or activates 3 downlink component carriers, and if downlink transmission modes of the3 downlink component carriers are all single-antenna transmission modes, the number n of bits of a hybrid automatic repeat request is determined_HARQIs 3; if the downlink transmission modes of the3 downlink component carriers are all multi-antenna transmission modes, the number n of bits of the hybrid automatic repeat request is_HARQIs 6.

For example, in the TDD system, a certain UE currently configures or activates 2 component carriers, and if downlink transmission modes of the 2 component carriers are all single-antenna transmission modes, the number n of bits of the harq is determined_HARQIs 2; if the downlink transmission mode of 1 component carrier is single-antenna transmission mode and the other 1 is multi-antenna transmission mode, the number n of bits of the hybrid automatic repeat request is_HARQIs 3.

Alternatively, the number of HARQ bits n_HARQThe number of component carriers configured or activated for the UE is multiplied by the maximum number of transport blocks that can be carried per PDSCH.

For example, s component carriers are currently configured or activated for a certain UE, each component carrier may send a PDSCH, and the maximum number of transport blocks that can be carried by each PDSCH is t, then the number of bits n of harq is n_HARQ＝st。

Alternatively, the number of HARQ bits n_HARQ2 times the number of component carriers configured or activated for the UE.

For example, if a UE currently configures or activates 2 component carriers, the number n of harq bits is_HARQIs 4.

Alternatively, the number of HARQ bits n_HARQCalculated as follows:

wherein n is_HARQ，cThe number of harq bits for component carrier c.

n_HARQ，cDetermined according to the rules of the LTE system.

In FDD system, the number of hybrid automatic repeat request bits n_HARQThe total number of transport blocks received for a UE on one subframe.

For example, a certain UE currently configures or activates 3 downlink ccs, and if the UE receives the PDSCH transmitted on 1 of the downlink ccs on a subframe, and the PDSCH carries 2 transport blocks, the number n of harq bits of the subframe_HARQIs determined to be 2; if the UE receives PDSCH transmitted on 2 downlink component carriers in a subframe, where one PDSCH carries 2 transport blocks and another PDSCH carries 1 transport block, the number n of harq bits of the subframe_HARQWas determined to be 3.
