Method and device for determining cascading of uci, terminal and network side device

A method for determining cascading of uplink control information (UCI), comprising:

• receiving on a first uplink channel, by a network side device, multiple UCIs with different priorities that are jointly encoded;
• and
• determining based on a first rule, by the network side device, a bit cascading order of the multiple UCIs with different priorities;
• wherein the first rule comprises:
• determining the bit cascading order of the multiple UCIs based on a priority order;
• or,
• determining the bit cascading order of the multiple UCIs based on UCI types, wherein a bit cascading order of multiple UCIs with a same UCI type is determined based on a priority order;
• wherein the multiple UCIs at least comprise Hybrid Automatic Repeat reQuest-ACKnowledge (HARQ-ACK).

A terminal, comprising a memory, a transceiver, and a processor;

• wherein the memory is configured to store a computer program, the transceiver is configured to transmit and receive data under control of the processor, and the processor is configured to read the computer program in the memory and perform following operations:
• determining, based on a first rule, a bit cascading order of multiple uplink control information (UCIs) with different priorities that are to be jointly encoded on a first uplink channel;
• wherein the first rule comprises:
• determining the bit cascading order of the multiple UCIs based on a priority order;
• or, determining the bit cascading order of the multiple UCIs based on UCI types, wherein a bit cascading order of multiple UCIs with a same UCI type is determined based on a priority order;
• and
• transmitting, on the first uplink channel, the multiple UCIs cascaded based on the bit cascading order;
• wherein the multiple UCIs at least comprise Hybrid Automatic Repeat reQuest-ACKnowledge (HARQ-ACK).
