Problems solved by technology

In the prior art, frequency domain resources occupied by PUCCHs of multiple DCIs corresponding to multiple slots are placed in the same position in the uplink system bandwidth, which leads to conflicts in the use of PUCCH resource positions, which in turn causes errors in UE transmission of UCI, and information High transmission error rate and low applicability

Abstract

The embodiment of the invention discloses a resource mapping method and device for an uplink control channel. The resource mapping method comprises the steps that terminal equipment obtains resource configuration information of the uplink control channel, wherein the resource configuration information includes parameters corresponding to first information, the information includes at least one ofsub-band information and second information of the terminal equipment, and the second information includes at least one of the following information: time-domain information and / or frequency-domain information of a resource on which downlink control information (DCI) of the terminal equipment is located, time slot type information of the terminal equipment and time-domain information and / or frequency-domain information of a resource on which a downlink shared channel data packet of the terminal equipment is located; and the terminal equipment determines an uplink control channel resource basedon the resource configuration information and transmits the uplink control information on the uplink control channel resource. The embodiment of the invention has the advantages that the occupation conflict of the uplink control channel resource can be avoided, and the transmission accuracy of the uplink control information is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource mapping method and device for an uplink control channel. Background technique [0002] The fifth-generation mobile communication technology (5th-Generation, 5G) communication system adopts an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) technology. A base station (eNodeB, eNB for short) sends information to a user equipment (user equipment, UE) through a limited number of OFDM symbols. In the 5G communication system, when the eNB sends information to the UE, it can send information in a time slot (slot, such as slot0), and can also send service data with higher priority in the minislot included in the slot. After receiving the information sent by the eNB, the UE needs to feed back the data sent by the eNB on slot0 (set as data 1) and the data sent by the eNB on the mini slot (set as data 2). In the 5G ...
