technical field

The present application relates to the communication field, and in particular to a communication method, device, communication equipment and storage medium.

Background technique

In the uplink carrier aggregation of new air interface (NR, New Radio), the number of uplink aggregated carriers reported by the terminal must be the carrier that can be sent simultaneously, that is, it depends on the number of transmission links of the terminal, and the network side is the terminal The maximum number of configured and activated uplink carriers is also equal to the number of aggregated uplink carriers reported by the terminal.

In the carrier aggregation scenario, NR allows to configure a secondary cell (SCell) that can transmit a physical uplink control channel (PUCCH, Physical Uplink Control Channel) for the terminal in addition to the special cell (SpCell, Special Cell). SCell is called PUCCH SCell, and the base station configures its hybrid automatic repeat request (HARQ-ACK) feedback for each downlink serving cell of the terminal on SpCell or PUCCH SCell.

Due to the limitation of uplink transmission links, as shown in Figure 1, the number of currently configured and activated uplink carriers/frequency bands can only be at most equal to the number of uplink transmission links, but the number of carriers/frequency bands for downlink carrier aggregation is greater than that of uplink carriers/frequency bands Therefore, for multiple frequency spectrums, all downlink carriers can be aggregated, but uplink carriers cannot be fully aggregated, and sufficient spectrum resources cannot be fully utilized.
