Description

Method and device for transmitting uplink control information, storage medium

Technical field

The present invention relates to a transmission technology of uplink control information, and in particular, to a method and device for transmitting uplink control information, and a storage medium, which are applied to a carrier aggregation system.

Background technique

The radio frame in the Long Term Evolution (LTE) system and the LTE-Advanced (LTE-A) system includes a Frequency Division Duplex (FDD) mode and a time division duplex ( TDD, Time Division Duplex mode frame structure. FIG. 1 is a schematic diagram of a frame structure in an existing LTE/LTE-A FDD system. As shown in FIG. 1, a 10 millisecond (ms) radio frame consists of twenty slots of length 0.5 to 0 and slots numbered 0 to 19. In the composition, the slots 2i and 2i+1 constitute a subframe i having a length of 1 ms. 2 is a schematic diagram of a frame structure in an existing LTE/LTE-A TDD system. A 10 ms radio frame is composed of two half frames having a length of 5 ms, and one field includes five subframes having a length of 1 ms. The subframe i is defined as two slots 2i and 2i+1 that are 0.5 ms long.

In the above two frame structures, for the Normal Cyclic Prefix, one slot contains seven symbols with a length of 66.7 microseconds (us), wherein the CP of the first symbol has a length of 5.21us, and the remaining six The CP length of the symbol is 4.69us; for the extended cyclic prefix (Extended Cyclic Prefix), one slot contains 6 symbols, and the CP length of all symbols is 16.67us. The supported uplink and downlink configurations are shown in Table 1:

Table 1

Wherein, for each subframe in a radio frame, "D" denotes a subframe dedicated for downlink transmission, "U" denotes a subframe dedicated for uplink transmission, and "S" denotes a special subframe, which includes downlink pilot DwPTS (Downlink Pilot Time Slot), guard interval (GP, Guard Period) and UpPTS (Uplink Pilot Time Slot).

In the frequency division duplex (FDD) system of LTE, since the uplink and downlink subframes are one-to-one correspondence, when the PDSCH includes only one transport block, the UE should feed back 1-bit ACK/NACK response information. When the PDSCH includes two transport blocks, the UE feeds back 2-bit ACK/NACK response information, and the UE transmits 1/2-bit ACK/NACK response information using PUCCH format 1a/1b. In a time division duplex (TDD) system, the uplink and downlink subframes are not one-to-one, that is, the ACK/NACK response information corresponding to multiple downlink subframes needs to be in the PUCCH of one uplink subframe. The channel is transmitted, and the downlink subframe set corresponding to the uplink subframe constitutes a “bundling window”. There are two methods for sending ACK/NACK response information: one is the binding method (bundling), and the core idea of the method is to ACK/NACK the transmission block corresponding to each downlink subframe that needs to be fed back in the uplink subframe. The information is logically ANDed. If a downlink subframe has 2 transport blocks, the UE should feed back 2-bit ACK/NACK response information. If each subframe has only one transport block, the UE should feed back 1-bit ACK/NACK response information. The UE uses the PUCCH format 1a/1b to transmit the 1/2 bit ACK/NACK response message; the other is the multiplexing with channel selection method, the core idea of which is to utilize different PUCCH channels and the channel. Different modulation symbols are used to indicate different feedback states of the downlink subframes to be fed back in the uplink subframe. If there are multiple transport blocks on the downlink subframe, the ACK/NACK fed back by the multiple transport blocks of the downlink subframe is performed first. The channel selection is performed after the logical bundling, and the UE uses the format 1b with channel selection to send an ACK/NACK response message.

The most notable feature of the LTE-A system over the LTE system is that the LTE-A system introduces a carrier aggregation technology, that is, aggregates the bandwidth of the LTE system to obtain a larger bandwidth. In a system that introduces carrier aggregation, a carrier that performs aggregation is called a component carrier (CC), which is also called a serving cell. At the same time, the concepts of the primary component carrier/cell (PCC/PCell, Primary Component Carrier/Cell) and the secondary component carrier/cell (SCC/SCell, Secondary Component Carrier/Cell) are also proposed. In the system in which carrier aggregation is performed, at least one primary serving cell and a secondary serving cell are included, wherein the primary serving cell is always in an active state, and the PUCCH is specified to be transmitted only on the Pcell.

In the LTE-A carrier aggregation system, when the HARQ-ACK response message is transmitted on the PUCCH, two transmission modes are defined: PUCCH format 1b combined channel selection (Format 1b with channel selection) and PUCCH format 3 (PUCCH format 3). For a UE that is configured with multiple serving cells, if the UE can only support a maximum of two serving cells, the UE will transmit the HARQ-ACK in the PUCCH format 1b joint channel selection manner; if the UE can support more than two services, The aggregation of the cell, the base station will use the high-level signaling to configure whether the UE adopts PUCCH format 1b joint channel selection or adopts PUCCH format 3 transmits HARQ-ACK response information. In the FDD system, PUCCH format3 adopts single Reed-Muller (RM) coding mode and supports up to 10 bits of HARQ-ACK transmission. In TDD system, PUCCH format3 adopts dual RM coding mode and supports up to 20 bits of HARQ-ACK transmission. . The TDD system also provides that when the number of HARQ-ACK bits to be transmitted is greater than 20, the HARQ-ACK to be transmitted is spatially bound and then transmitted using PUCCH format 3.

In the prior art, the PUCCH format 3 supports a maximum of 10/20 bits of HARQ-ACK transmission. Considering that a carrier aggregation technology of more than five serving cells may be supported in subsequent versions, the number of HARQ-ACK bits to be transmitted is far more than 20 bits. Therefore, PUCCH format3 cannot be used for transmission.

At present, related technologies for transmitting uplink control information when carrier aggregation of more than 5 serving cells are not available are available for reference.

Example one

It is assumed that the number of the aggregated serving cells is 6, because the number of aggregated serving cells is less than or equal to 10, and the second method is used to obtain the HARQ-ACK information to be sent:

When each serving cell corresponds to one codeword stream, the HARQ-ACK information to be transmitted is {HARQ-ACK(0), HARQ-ACK(1), HARQ-ACK(2), ..., corresponding to each serving cell. HARQ-ACK (5)}, as shown in Figure 4 (a);
