Description

Method and device for transmitting uplink control information

Technical field

The present application relates to, but is not limited to, the field of communications technologies, and in particular, to a method and an apparatus for transmitting uplink control information.

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. 1 is a schematic diagram of a frame structure in an LTE/LTE-A FDD system in the related art. As shown in FIG. 1, a 10 millisecond (ms) radio frame consists of 20 time slots with a length of 0.5 ms and numbers 0 to 19 ( The time slots 2i and 2i+1 constitute a subframe of length 1 ms; FIG. 2 is a schematic diagram of a frame structure in the LTE/LTE-A TDD system in the related art, and a radio frame with a period T _f of 10 ms It consists of two half frames of 5 ms length. One field consists of five subframes with a length of 1 ms. The slots 2i and 2i+1 form a subframe i of length 1 ms, where T _slot represents the slot. Duration, T _s represents a basic time unit, DwPTS represents a Downlink Pilot Time Slot, GP represents a Guard Period, and UpPTS represents an Uplink Pilot Time Slot.

A physical uplink control channel (PUCCH) format is defined in the LTE system, including PUCCH format 1/1a/1b and format 2/2a/2b, where format1 is used to transmit user equipment. (UE, User Equipment) scheduling request (SR, Scheduling Request) signal, format 1a is used to feed back 1-bit acknowledgment (ACK, ACK (Acknowledgement) / Negative Acknowledgment (NACK) response message, format 1b is used for feedback 2-bit ACK/NACK response message; format 2 is used to transmit downlink channel state information (CSI), format 2a is used to send CSI and 1-bit ACK/NACK response message, and format 2b is used to send CSI information. And a 2-bit ACK/NACK response message.

The salient features of the LTE-A system over the LTE system include the introduction of carrier aggregation in the LTE-A system. Technology, that is, the bandwidth of the LTE system is aggregated to obtain a larger bandwidth. In the LTE-A system that introduces carrier aggregation, the carrier to be aggregated is called a component carrier (CC), which is also called a serving cell (SC, Serving Cell). Meanwhile, the LTE-A system also proposes a principal component. The concept of carrier/cell (PCC/PCell, Primary Component Carrier/Cell) and secondary component carrier/cell (SCC/SCell, Secondary Component Carrier/Cell). In a 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 primary serving cell (Pcell, Primary Cell).

In the LTE-A carrier aggregation system, two types of transmission modes are defined for the hybrid automatic repeat request acknowledgement message (HARQ-ACK, Hybrid Automatic Repeat request Acknowledgment): PUCCH format 1b combined channel selection (Format 1b with channel selection) is used for transmission. And transmitting in 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, For the aggregation of the cell, the base station configures whether the UE uses the PUCCH format 1b joint channel selection manner or the PUCCH format 3 to transmit the HARQ-ACK information through the high layer signaling.

In the FDD system, PUCCH format3 adopts a single Reed-Muller coding scheme to support up to 10 bits of HARQ-ACK transmission. In the TDD system, PUCCH format 3 adopts dual RM coding mode to support Up to 20 bits of HARQ-ACK transmission. It is also stipulated in the TDD system 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. When HARQ-ACK and CSI need to be transmitted simultaneously, the existing system specifies that if the supported CSI and HARQ-ACK (including SR) are smaller than the maximum load of PUCCH format 3, then HARQ-ACK (including SR) and CSI are simultaneously transmitted, otherwise only Send HARQ-ACK (including SR). The CSIs that do not support multiple serving cells in the LTE-A system are simultaneously transmitted in the same subframe.

In the related art, the PUCCH format 3 supports up to 20 bits of HARQ-ACK transmission. In subsequent versions, the carrier aggregation technology of up to 32 serving cells is supported, but the PUCCH format in the related art cannot transmit uplink control information corresponding to 32 serving cells. (UCI, Uplink Control Information), therefore, introducing a new PUCCH format to transmit UCI, how to use the new PUCCH format to send UCI is an urgent problem to be solved.

The apparatus according to claim 54, wherein the sending module is configured to: determine a PUCCH format used for uplink control information transmission, and determine a PUCCH resource corresponding to the PUCCH format used for uplink control information transmission;

The PUCCH format for the uplink control information transmission includes: a PUCCH format that can carry the most uplink control information bits in the PUCCH format that can support the uplink control information; or a PUCCH format corresponding to the HARQ-ACK; or a PUCCH corresponding to the CSI format.
The apparatus according to claim 59, wherein the sending module is further configured to: when the determined PUCCH format for uplink control information transmission corresponds to one PUCCH resource, use the PUCCH resource as a PUCCH for uplink control information transmission If the PUCCH resource corresponding to the PUCCH format is greater than one, the PUCCH resource with the largest number of PRBs is selected as the PUCCH resource corresponding to the PUCCH format; or the PUCCH resource corresponding to the HARQ-ACK is selected as the PUCCH format. Corresponding PUCCH resources; or, the PUCCH resources corresponding to the maximum supportable load are selected as the PUCCH resources corresponding to the PUCCH format; or the PUCCH resources corresponding to the smallest supportable load are selected as the PUCCH resources corresponding to the PUCCH format.
The device according to claim 33, wherein the sending module is configured to: when the resource corresponding to the PUCCH is indicated by the value of the acknowledgment/negative acknowledgment resource indication ARI, determine the resource corresponding to the PUCCH according to the value of the latest ARI, And transmitting uplink control information by using the determined PUCCH resource.
