Description

Method and device for sending and receiving uplink control information

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a device and a system for sending and receiving uplink control information.

Background

In a Long Term Evolution (LTE) system, time-Frequency resources are divided into Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain dimension or Single Carrier-Frequency Division Multiplexing Access (SC-FDMA) symbols in a Frequency domain dimension, and a time-Frequency lattice point formed by one time-domain symbol in the time domain and one subcarrier in the Frequency domain. In the LTE system, the transmission of traffic is scheduled based on a base station, and a basic time unit scheduled by the base station is one subframe, and one subframe includes multiple time domain symbols. The specific scheduling procedure is that the base station sends a Control Channel, such as a Physical Downlink Control Channel (PDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH), where the Control Channel may carry scheduling information of a data Channel, such as a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH), and the scheduling information includes Control information, such as resource allocation information and a modulation and coding scheme. User Equipment (UE) detects a control channel in a subframe, and receives a downlink data channel or transmits an uplink data channel according to scheduling information carried in the detected control channel. In LTE, when data transmission is performed, Physical Resource Blocks (PRBs) are formed by uplink and downlink time-frequency domain Physical resources, where one PRB includes 12 consecutive subcarriers in the frequency domain and 7 consecutive OFDM symbols (6 in the case of Extended CP) in the time domain, that is, the frequency domain width Δ f is 180kHz and the time length is 0.5 ms. Two PRBs constitute a Pair of Physical Resource blocks (PRB-Pair), which is the minimum mapping granularity of Physical layer channel resources. The LTE system supports a Carrier Aggregation (CA) technique, in which a base station configures a plurality of carriers to one UE to increase a data transmission rate of the UE. In CA, multiple carriers transmitted by a base station are synchronized in time, and a UE detects a PDCCH and a corresponding PDSCH of each carrier, respectively, and the detection process for each carrier is similar to that of a single carrier. The LTE system supports Frequency Division Duplex (FDD) CA, Time Division Duplex (TDD) CA, and FDD + TDD CA. For TDD CA, TDD CA with the same uplink and downlink configuration and TDD CA with different uplink and downlink configurations are divided. At present, the LTE supports the aggregation of maximum 5 downlink carriers; the UE supporting the CA technology may simultaneously detect downlink data carried on multiple downlink carriers, and the UE needs to perform a feedback mechanism of Hybrid Automatic Repeat Request (HARQ) on the downlink data carried on the multiple downlink carriers at the same time.

An existing transmission method of UCI information is: in the CA mode, there is one primary carrier and at least one secondary carrier, and a Physical Uplink Control Channel (PUCCH) carrying a Hybrid Automatic Repeat Request-acknowledgement (HARQ-ACK) is transmitted only on the primary carrier of the UE. The PUCCH transmission mode in the CA mode includes two modes of a channel selection mode and a PUCCH format 3. In the channel selection mode, the PUCCH format 1a/1b is adopted for HARQ-ACK feedback, but the channel selection mode supports CA of at most two carriers, so that the application scene of the CA mode is limited; the PUCCH format 3 mode adopts a DFT-S-OFDM (Discrete Fourier Transform-Spread-Orthogonal frequency division Multiplexing) transmission structure, and can support transmission of UCI of at most 20 bits and TDD CA of 5 carriers. For example, taking TDD uplink and downlink configuration 2 deployed in a current network as an example, uplink subframe 2 of one carrier may support feedback of 4 bits, and CA of TDD uplink and downlink configuration 2 of 5 carriers is 20 bits.

However, this transmission method can only support transmission of UCI of 20 bits at most, and cannot support feedback of UCI of more than 20 bits.

When the ue determines that the carrier included in the first carrier only belongs to the first carrier group, the ue transmits CSI corresponding to the first carrier on the first resource block.

It can be understood that, if the carrier included in the first carrier belongs to the first carrier group and the second carrier group, the ue transmits CSI corresponding to the first carrier on the first resource block and the second resource block, where the first resource block and the second resource block are in a frequency division relationship or a time division relationship, and the first resource block and the second resource block may have the same size or different sizes, for example: the size of a resource block is smaller than or the same as the size of one PRB-Pair or larger than the size of one PRB-Pair, e.g. the same as the size of two PRB-pairs.

For convenience of understanding, the following describes a method for sending uplink control information in an embodiment of the present invention in an actual application scenario:

the base station pre-configures carrier aggregation of 10 carriers for the user equipment A, and divides the 10 downlink carriers into a first carrier group and a second carrier group. The first downlink carrier group includes carriers 1 to 5, and the second carrier group includes carriers 6 to 10.

The user equipment determines a first carrier wave of Channel State Information (CSI) to be fed back. When the first carrier includes one carrier, the first carrier belongs to the first carrier group or the second carrier group, or if the first carrier includes at least two carriers, the first carrier belongs to the first carrier group and/or the second carrier group.

And the user equipment determines the corresponding relation between the first carrier group and the first resource block and the corresponding relation between the second carrier group and the second resource block according to the indication information of the base station or the information of the preset value.

If the first carrier is carrier 1, carrier 3, carrier 4, carrier 5, carrier 6, carrier 7, the ue transmits CSI corresponding to the first carrier on the first resource block and the second resource block because some of the first carriers belong to the first carrier group and some of the first carriers belong to the second carrier group.

If the first carrier is carrier 1, carrier 3, carrier 4, since the first carrier only belongs to the first carrier group, the ue transmits CSI corresponding to the first carrier on the first resource block.

If the first carrier is carrier 7, carrier 8, carrier 10, since the first carrier only belongs to the second carrier group, the ue transmits CSI corresponding to the second carrier on the second resource block, or transmits CSI corresponding to the first carrier on the first resource block and the second resource block.

The user equipment indicates the position and/or size of the resource block which is determined by the user equipment and used for feeding back the CSI corresponding to the first carrier to the base station through the demodulation reference signal. Specifically, the position and/or size of the demodulation reference signal and the resource block, which is determined by the user equipment and used for feeding back the CSI corresponding to the first carrier, have a preset corresponding relationship, including that, after the user equipment determines the resource block used for feeding back the CSI corresponding to the first carrier, the corresponding demodulation reference signal is correspondingly sent, specifically, the position and/or size of the resource block corresponding to the CSI of data on the first carrier can be indicated through one or a combination of the following attributes of the demodulation reference signal, or the resource block corresponding to the CSI of data on the first carrier and the carrier group to which the first carrier corresponding to the CSI transmitted in the resource block belongs can be indicated:

The demodulation reference signals sent on different time resources respectively correspond to whether a resource block used by the user equipment for feeding back the CSI corresponding to the first carrier is a first resource block, a second resource block, or the first resource block and the second resource block.
