[0034] Such as figure 2 As shown, the embodiment of the present invention provides a method for transmitting uplink control information, which specifically includes the following steps:

[0035] Step 21: Obtain the downlink control information sent by the access point.

[0036]Among them, the downlink control information (DCI) includes the same field as when scheduling the uplink transmission channel, and the value of this field is different from all possible values ​​when scheduling the uplink transmission channel. This means that the DCI still uses the existing standard The length of the field is to achieve compatibility with existing standards, and the value of this field is different from the possible values ​​of this field defined in the existing standard.

[0037] Wherein, the uplink transmission channel may be an uplink transmission channel for transmitting uplink data signals, such as PUSCH, or an uplink transmission channel for transmitting uplink control signals, s...

[0046] Such as image 3 As shown, the second embodiment of the present invention provides a method for transmitting uplink control information, which specifically includes the following steps:

[0047] Step 31: Obtain the downlink control information sent by the access point.

[0048] Step 32: According to the resource allocation information in the downlink control information, instruct the uplink control information to be transmitted using the extended physical uplink control channel ePUCCH or the physical uplink shared channel PUSCH.

[0049] Wherein, the downlink control information DCI includes resource allocation and other control information on one or more UEs, and the resource allocation information includes modulation and coding strategy (MCS, Modulation and Coding Scheme), resource allocation information (Resource allocation) and other information. Further, the value of the first field corresponding to the resource allocation information here is different from the po...

[0061] Such as Figure 4 As shown, the third embodiment of the present invention provides a method for transmitting uplink control information, which specifically includes the following steps:

[0062] Step 41: Obtain downlink control information sent by the access point.

[0063] Step 42: According to the joint value of the new data indication information and the redundancy version information in the downlink control information, determine that the uplink control information is transmitted using the extended physical uplink control channel ePUCCH or the physical uplink shared channel PUSCH.

[0064] Wherein, the downlink control information DCI includes resource allocation and other control information on one or more UEs, specifically including modulation and coding strategy (MCS, Modulation and Coding Scheme), resource allocation information (Resourceallocation), redundancy version information ( RV, Redundancy Version), new data indication information (NDI, new date indicat...

Abstract

The present invention provides a transmission method, device and user terminal for uplink control information, the method comprising: obtaining the downlink control information sent by the access point, so as to determine that the uplink control information is transmitted using ePUCCH or PUSCH; when determining the uplink control information, use When the ePUCCH is transmitted, the scheduled ePUCCH is used to transmit the uplink control information to be transmitted; or, when it is determined that the uplink control information is transmitted using the PUSCH, the scheduled PUSCH is used to transmit the uplink control information to be transmitted. The present invention uses the undefined idle state in the downlink control information to indicate that the uplink control information is transmitted using ePUCCH or PUSCH, without adding new indication information, and realizes indicating the uplink control information without changing the size of DCI in the scheduling information The purpose of which uplink transmission channel is used for transmission saves network transmission resources, and the traditional blind detection method can be used to perform blind detection on DCI, avoiding the problem of increased blind detection complexity caused by changing the size of DCI.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and user terminal for transmitting uplink control information. Background technique [0002] Such as figure 1 The schematic diagram of the basic architecture of the mobile communication network is shown. The mobile communication system refers to that the operator deploys wireless access network equipment (such as base stations) and core network equipment (such as Home Location Register HLR, Home Location Register), etc., to provide user terminals ( Mobile terminals such as mobile phones) systems that provide communication services. [0003] Mobile communication has experienced the first generation, second generation, third generation, and fourth generation. The first generation of mobile communication refers to the initial analog, voice-only cell phone standard, which mainly uses analog technology and frequency division multiple access (FDMA, F...
