Embodiment 1

[0140] When the terminal enables the uplink transmission skipping (UL skipping) function of the uplink data channel (PUSCH), and when the terminal has the uplink control channel (PUCCH) carrying UCI and the dynamically scheduled PUSCH conflicts in time, the terminal physically layer generates virtual information bits or signals such as Figure 4 As shown, a virtual TB is generated before step 401, a PUSCH is constructed, and UCI is multiplexed onto the PUSCH.

[0141] In this embodiment, the terminal adds operations such as CRC, channel coding, and modulation to the generated virtual TB, so it takes a long time to process virtual information bits. However, when receiving the PUSCH, the network device can learn that the PUSCH bears a virtual TB through CRC check. In addition, the PUSCH carries coded information, which can improve the success rate of network equipment reception.

Embodiment 2

[0143] When the terminal enables the uplink transmission skipping (UL skipping) function of the uplink data channel (PUSCH), and when the terminal has the uplink control channel (PUCCH) carrying UCI and the dynamically scheduled PUSCH conflicts in time, the terminal physically layer generates virtual signals such as Figure 5 As shown, before step 508, a virtual modulation symbol is generated, a PUSCH is constructed, and UCI is multiplexed onto the PUSCH.

[0144] In this embodiment, the terminal does not need to add operations such as CRC, channel coding, and modulation to the generated virtual TB, so the time required to process the virtual signal is relatively short. Such as Figure 5 As shown, steps 501 to 507 indicated by dotted lines are not executed.

[0145] It should be noted that, in this embodiment, the situation that the terminal has data to be transmitted is not limited, for example, the execution may start from step 501 .

Embodiment 3

[0147] When the terminal enables the uplink transmission skipping (UL skipping) function of the uplink data channel (PUSCH), and when the terminal has the uplink control channel (PUCCH) carrying UCI and the dynamically scheduled PUSCH conflicts in time, the terminal physically layer generates virtual signals such as Image 6 As shown, a virtual signal sequence is generated before step 609, a PUSCH is constructed, the PUSCH includes the virtual signal sequence, and UCI is multiplexed onto the PUSCH.

[0148] In this embodiment, the terminal does not need to add operations such as CRC, channel coding, and modulation to the generated virtual TB, so the time required to process the virtual signal is relatively short. When receiving the PUSCH, the network device may perform sequence blind detection to determine whether the virtual signal carried by the PUSCH is an actually transmitted signal.

[0149] It should be noted that, in this embodiment, the situation that the terminal has...

Abstract

The invention provides an uplink transmission method and device and a terminal. The method comprises the steps: obtaining a virtual information bit or a virtual signal, and carrying the virtual information bit or the virtual signal on a first PUSCH; multiplexing the UCI to the first PUSCH for transmission. The problem that the UCI cannot be transmitted can be avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an uplink transmission method, device and terminal. Background technique [0002] Some communication systems (for example: 5G systems) support multiplexing of uplink control information (Uplink Control Information, UCI) and transmission on a physical uplink shared channel (Physical uplink shared channel, PUSCH). However, in practical applications, the terminal may have no uplink data transmission, so that the UCI cannot be multiplexed and transmitted on the PUSCH, resulting in the problem that the UCI may not be transmitted. Contents of the invention [0003] Embodiments of the present application provide an uplink transmission method, device, and terminal, which can solve the problem that UCI cannot be multiplexed and transmitted on the PUSCH, resulting in that UCI may not be transmitted. [0004] In the first aspect, the embodiment of the present applica...
