For the extended cyclic prefix (Extended Cyclic Prefix), one slot contains 6 symbols, and the CP length of all symbols is 16.67 us.

图 3为现有技术 LTE-A***中实现载波聚合的示意图，如图 3所示， LTE-A***采用载波聚合 ( carrier aggregation )技术扩展传输带宽，每个聚合的载波称为一个分量载波（CC, Component Carrier ), 又称为一个小区 3 is a schematic diagram of implementing carrier aggregation in the LTE-A system in the prior art. As shown in FIG. 3, the LTE-A system uses carrier aggregation technology to extend the transmission bandwidth, and each aggregated carrier is called a component carrier ( CC, Component Carrier ), also known as a community

( cell )₀ 多个分量载波可以是连续的，也可以是非连续的；可以位于同一频段（ operating band ), 也可以位于不同频段。 (cell) ₀ multiple component carriers may be continuous or non-contiguous; may be located in the same The operating band can also be in different frequency bands.

现有技术提出， LTE-A***中，用户设备可以在多个配置的（ configured ) 或激活的（ activated )分量载波上同时接收多个 PDSCH。多个 PDSCH的应答信息在一个 UE特定的（ UE specific )分量载波上通过一个 PUCCH发送。该 UE特定的分量载波称为主分量载波（ PCC, Primary Component Carrier ), 又称主小区 ( Pcell, Primary Cell )。 The prior art proposes that in an LTE-A system, a user equipment can simultaneously receive multiple PDSCHs on multiple configured or activated component carriers. The response information of the plurality of PDSCHs is transmitted through one PUCCH on one UE-specific (UE specific) component carrier. The UE-specific component carrier is called a primary component carrier (PCC), and is also called a primary cell (Pcell, Primary Cell).

针对 LTE-A***，将按照公式（ 3 )来进行 PUCCH功率的控制，尸 PUCCH W ^{= min} {PcMAX,cO'),尸 0— PUCCH ^{+ PL}c ⁺ — PUCCH (^F) ^{+ A}TxD (^') + ^( } (3) 其中， ^PCMAX，_e(0是对于服务小区 _c的第 i个子帧上的最大发射功率。 h 是一个基于 PUCCH格式的值， ^p 为服务小区 C上的 UE测量并计算的下行路损估计， ^AtxD (^F')是根据不同的 PUCCH格式 ^来设置的传输分集功率补偿，其取值可以为 {0, -1, -2, -3} dB, 但是不局限于此数值集合。 For the LTE-A system, PUCCH power control will be performed according to formula (3), corpse PUCCH W ^{= min} {PcMAX, cO'), corpse 0 - PUCCH ^{+ PL} c ⁺ - PUCCH ( ^F ) ^{+ A} TxD (^' + ^( } (3) where ^P CMAX, _e (0 is the maximum transmit power for the i-th subframe of the serving cell _c . h is a value based on the PUCCH format, ^p is the UE measurement on the serving cell C And the calculated downlink path loss estimate, ^AtxD ( ^F ') is the transmission diversity power compensation set according to different PUCCH formats, which can be {0, -1, -2, -3} dB, but not limited. This set of values.

为承载多个 PDSCH的应答信息， LTE-A***中引入了一种新的 PUCCH 格式，称为第三 PUCCH格式（ PUCCH format 3 )。当前， LTE-A***最多能聚合 5个分量载波，如果 UE对每个 PDSCH反馈的 ACK/NACK需要 1 至 2bits (每个 PDSCH可承载 1至 2个传输块（ TB, Transport Block ), 每个 TB 需要反馈 lbit ACK/NACK ), 则 PUCCH format 3 需要承载的 ACK/NACK为 1至 10bits。除此之外，如果还包括 lbit调度请求信息（ SR ), 则 PUCCH format 3需承载的信息量为 1至 llbits。 To carry the response information of multiple PDSCHs, a new PUCCH format, called the third PUCCH format (PUCCH format 3), is introduced in the LTE-A system. Currently, the LTE-A system can aggregate up to 5 component carriers. If the UE needs ACK/NACK for each PDSCH feedback, it needs 1 to 2 bits (each PDSCH can carry 1 to 2 transport blocks (TB, Transport Block), each TB needs to feed back lbit ACK/NACK), then the ACK/NACK that PUCCH format 3 needs to bear is 1 to 10 bits. In addition, if lbit scheduling request information (SR) is also included, the amount of information to be carried by PUCCH format 3 is 1 to llbits.

但是，在基于 TDD的***下，由于一个上行子帧可以对应于多个下行子帧，如果采用了载波聚合，那么，原有的 PUCCH格式中的雷德 -穆雷 Reed-Muller ( 32,0 )的编码方式最多可以传输 13比特信息是不够用的。还有一种方式就是将需要反馈的 ACK/NACK 划分为两组，分别对各组进行 RM ( 24,0 )编码，对各组进行调制和极联（或者先极联再调制）。 However, in a TDD-based system, since one uplink subframe can correspond to multiple downlink subframes, if carrier aggregation is used, the Reed-Muller (32,0) in the original PUCCH format It is not enough to encode up to 13 bits of information. There is also a way to divide the ACK/NACK that needs feedback into two groups, respectively RM (24,0) encoding each group, and modulating and pole-connecting each group (or first-pole re-modulation).

用户设备是否使用 PUCCH format 3发送上行控制信息是由高层配置的。 PUCCH format 3相比于 PUCCH format l/la/lb/2/2a/2b可承载的信息量不同，编码方式不同，信道结构和信道化方式也有不同。比如在产生时域的单载波频分多址 ( SC-FDMA, Single Carrier-Frequency Division Multiple Access )信号前，不同于 PUCCH format l/la/lb/2/2a/2b, PUCCH format 3 还进行了传输预编码 ( transform precoding ), 因而 PUCCH format 3产生的 SC-FDMA信号又称为 DFT-S-OFDM信号。 Whether the user equipment uses PUCCH format 3 to send uplink control information is configured by the upper layer. of. Compared with PUCCH format l/la/lb/2/2a/2b, PUCCH format 3 can carry different amounts of information, different coding modes, and different channel structures and channelization modes. For example, before the single-carrier frequency division multiple access (SC-FDMA, Single Carrier-Frequency Division Multiple Access) signal is generated in the time domain, unlike PUCCH format l/la/lb/2/2a/2b, PUCCH format 3 is also performed. The transmission precoding is transmitted, and thus the SC-FDMA signal generated by the PUCCH format 3 is also referred to as a DFT-S-OFDM signal.

在基于 TDD的***下，有一种复用（multiplexing )的反馈应答信息的方法。其核心思想是利用不同的 PUCCH信道和该信道上不同的调制符号来表示需要在该上行子帧反馈的下行子帧的不同反馈状态，如果下行子帧上有多个 TB, 那么，先将下行子帧的多个传输块反馈的 ACK/NACK进行逻辑与（ spatial bundling )后再进行信道选择，然后使用 PUCCH format lb发送。当 UE在当前子帧没有 PUSCH要发送时， UE将在 PUCCH上采用格式 lb联合信道选择 ( format lb with channel selection )的方式来发送这多个 ACK/NACK应答消息。 Under TDD-based systems, there is a way to multiplex feedback feedback information. The core idea is to use different PUCCH channels and different modulation symbols on the channel to indicate different feedback states of the downlink subframes that need to be fed back in the uplink subframe. If there are multiple TBs in the downlink subframe, then the downlink is first. The ACK/NACK fed back by the plurality of transport blocks of the subframe is logically ANDed (channel bundling) and then channel selected, and then transmitted using PUCCH format lb. When the UE does not have a PUSCH to transmit in the current subframe, the UE will transmit the multiple ACK/NACK response messages on the PUCCH by using format lb with channel selection.

在 LTE-A***中，对于 TDD模式下，在采用复用的反馈方式以及 format 3的反馈方式时，如何配置 PUCCH的功率控制参数没有给出具体解决方案。发明内容 In the LTE-A system, in the TDD mode, when the multiplexed feedback mode and the format 3 feedback mode are adopted, how to configure the PUCCH power control parameters does not give a specific solution. Summary of the invention
