Abstract: Embodiments of the present disclosure provide a frequency hopping indication method and apparatus. The method is applied to a terminal device, and comprises: receiving high-layer signaling sent by a network device, the high-layer signaling being configured with a first frequency hopping mode or candidate frequency hopping modes; and determining, on the basis of the high-layer signaling, a frequency hopping mode of an uplink channel corresponding to the terminal device. According to the frequency hopping indication method and apparatus provided in the embodiments of the present disclosure, the first frequency hopping mode of the uplink channel is determined according to the high-layer signaling by configuring the newly added first frequency hopping mode in the high-layer signaling; and when frequency hopping modes are configured in the high-layer signaling, dynamic switching between frequency hopping modes is implemented.

Abstract: The present disclosure provides a method and a device for determining cascading of UCI, a terminal and a network side device. The method includes: determining based on a first rule, by a terminal, a bit cascading order of multiple UCIs with different priorities that are to be jointly encoded on a first uplink channel, where the first rule includes: determining the bit cascading order of the multiple UCIs based on a priority order preferentially; or, determining the bit cascading order of the multiple UCIs based on UCI types preferentially, where a bit cascading order of multiple UCIs with a same UCI type is determined based on a priority order; and transmitting, by the terminal, on the first uplink channel, the multiple UCIs cascaded based on the bit cascading order.

Abstract: Embodiments of the present application provide a method for determining the number of repeated transmissions of a physical uplink control channel (PUCCH), and a terminal and base station, comprising: determining the number of repeated transmissions of a PUCCH according to received target information; said target information comprises first information or second information, said first information comprises a PUCCH resource indicator (PRI) field in downlink control information (DCI), said second information comprises control information carried by the DCI, a media access control control element (MAC CE), or a group common physical downlink control channel (PDCCH). The embodiments of the present application enable a dynamic indication process of the number of PUCCH repeated transmissions.
