Embodiment Construction

[0207] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0208] Such as figure 1 As shown, the embodiment of the present invention provides a hybrid automatic repeat request feedback processing method, including:

[0209] Step 101: Receive first downlink control information, where the first downlink control information is used for multi-slot scheduling or multi-carrier scheduling or for scheduling multiple physical downlink shared channel transmissions, and the first downlink control information The control information includes first indication information, where the first indication information is used to indicate the position of the same feedback time slot corresponding to all first physical downlink shared channels, where the first physical downlink shared channels are the first downlink Physical downlink ...

Abstract

The invention provides a hybrid automatic repeat request feedback processing method, device and equipment, and relates to the technical field of communication. The method comprises the following steps: receiving first downlink control information, wherein the first downlink control information is used for multi-slot scheduling or multi-carrier scheduling or scheduling transmission of a plurality of physical downlink shared channels, wherein the first downlink control information comprises first indication information, the first indication information is used for indicating the positions of thesame feedback time slot corresponding to all first physical downlink shared channels, and the first physical downlink shared channels are physical downlink shared channels scheduled by the first downlink control information; and feeding back first feedback information on the feedback time slot, wherein the first feedback information comprises feedback information of all first physical downlink shared channels scheduled corresponding to the first downlink control information. According to the scheme of the invention, overlarge DCI overhead in multi-time slot scheduling is avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a hybrid automatic repeat request feedback processing method, device and equipment. Background technique [0002] At present, 5G new air interface NR supports a physical downlink control channel PDCCH to schedule a physical downlink shared channel PDSCH transmission, and for carrier aggregation with different subcarrier spacing SCS configurations, when the SCS configured by the scheduling carrier is smaller than the SCS configured by the scheduled carrier, in order to reduce Scheduling the PDCCH overhead on the carrier will also support one PDCCH to schedule different PDSCH transmissions in multiple time slots. [0003] However, for the downlink control information DCI scheduled by multi-slots, only the feedback position of one scheduled PDSCH can be indicated separately, which will make the DCI overhead too large. Contents of the invention [0004] The pu...
