Problems solved by technology

[0003] In the related art, when the uplink shared channel (for example, Physical Uplink Shared Channel (PUSCH)) of the terminal device is a channel configured and authorized, if the uplink control channel (for example, Physical Uplink Control Channel (Physical Uplink Control Channel, There is a resource conflict between the time domain resources of PUCCH) and the time domain resources of the dynamically scheduled uplink shared channel. Since PUSCH may have no data to send, the MAC layer generates PDUs based on whether there is data, and cannot generate PDUs based on whether there is UCI to be multiplexed.

[0156] When the UE is configured with at least one PUSCH configured with grants on one or more carriers, if the UE receives one or more UL grants, at least one PUSCH on one or more carriers is scheduled, and the UE receives one or more DLgrant, when one or more PUCCHs carrying UCI are scheduled, the UE can determine the transmission of UCI according to the following steps:

[0157] Step 11: Decode DL grant and / or UL grant.

[0158] Step 12: If there are multiple PUCCHs, the PHY layer determines the resource of the target PUCCH bearing UCI according to the multiplexing rule of UCI on PUCCH.

[0159] Step 13: If the target PUCCH resource conflicts with at least one PUSCH on the above-mentioned one or more carriers, the PHY layer determines the target PUSCH resource for carrying UCI in at least one PUSCH according to the UCI on PUSCH multiplexing priority .

[0160] Step 14: The PHY layer notifies the MAC layer of UCI multiplexing information (that is, the content in step 13), ...

[0177] Step 31: Decode DL grant and / or UL grant.

[0178] Step 32: The PHY layer notifies the MAC layer after step 31 that the one or more PUCCHs carrying UCI conflict with at least one PUSCH on the one or more carriers.

[0179] Step 33: The MAC generates a MAC PDU for the first PUSCH (set) in conflict according to the UCI multiplexing information.

[0180] Step 34: If there is no UL-SCH, the MAC generates padding PDU.

Abstract

The invention discloses an uplink transmission method, an uplink transmission device and network equipment, belongs to the technical field of communication, and aims to realize that an MAC (Media Access Control) layer can generate a PDU (Protocol Data Unit) based on whether UCI (Uplink Control Interface) needs to be multiplexed or not. The method comprises the following steps: under the condition that the time domain resource of at least one uplink shared channel configured with authorization is overlapped with the time domain resource of at least one uplink control channel, generating an MAC PDU (Media Access Control Protocol Data Unit) on an MAC layer according to any one of the following processing modes: if the MAC layer knows that the time domain resource of the uplink shared channel is overlapped with the time domain resource of the uplink control channel, generating an MAC PDU; generating an MAC PDU (Media Access Control Protocol Data Unit) according to multiplexing information notified to the MAC layer by the physical layer; wherein the at least one uplink control channel carries at least one piece of uplink control information.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to an uplink transmission method, device and terminal equipment. Background technique [0002] When the uplink shared channel (for example, Physical Uplink Shared Channel, PUSCH) of the terminal device is a channel configured with authorization, and there is no data to be transmitted in the data memory of the terminal device, the terminal can also ignore the configuration authorization (configured grant) PUSCH, no uplink transmission. [0003] In the related art, when the uplink shared channel (for example, Physical Uplink Shared Channel (PUSCH)) of the terminal device is a channel configured and authorized, if the uplink control channel (for example, Physical Uplink Control Channel (Physical Uplink Control Channel, There is a resource conflict between the time domain resources of PUCCH) and the time domain resources of the dynamically scheduled uplink s...
