Embodiment 1

[0154] In this example, if Figure 8 As shown, on the base station and / or network side, if the network side configures skipUplinkTxDynamic with a value of true, and the scheduled PUSCH resources and PUCCH resources overlap in time, in order to reduce the complexity of blind detection (that is, to determine whether UCI is on PUCCH or When transmitting on the PUSCH), the network side should indicate in the UL grant, in the relevant fields as defined above, that no matter what the conditions and situations are, the UL-SCH is always transmitted on the PUSCH.

[0155]On the terminal and / or user side, the physical layer entity of the terminal demodulates the UL grant, and submits the information received in the UL grant to the MAC entity, and the MAC entity of the terminal judges whether to generate MAC PDUs. That is, the MAC entity does not generate a MAC PDU for the HARQ entity if all of the following conditions are met:

[0156] The parameter skipUplinkTxDynamic of the MAC enti...

Embodiment 2

[0162] In this example, if Figure 9 As shown, the inter-layer signaling from the internal physical layer to the MAC layer of the terminal is defined. When the physical layer of the terminal realizes that the resources of the scheduled PUSCH and PUCCH overlap in the time domain, the terminal is optionally configured with the value If skipUplinkTxDynamic is true, the physical layer of the terminal will notify the MAC layer to unconditionally generate a MAC PDU for the currently scheduled HARQ entity.

[0163] It should be noted that, for the PDU generating method provided in the embodiment of the present application, the execution subject may be the PDU generating device, or a module in the PDU generating device for executing the loading PDU generating method. In the embodiment of the present application, the PDU generating method performed by the PDU generating device is taken as an example to illustrate the PDU generating method provided in the embodiment of the present appli...

Abstract

The invention discloses a protocol data unit generation method, a configuration method, a device and electronic equipment and belongs to the technical field of communication. The protocol data unit generation method is applied to a terminal. The method comprises the following steps: a media access control (MAC) entity of the terminal generates an MAC protocol data unit (PDU) for a currently scheduled hybrid automatic repeat request (HARQ) entity according to at least one of the following items: first indication information sent by network side equipment, second indication information sent by a physical layer entity to the MAC entity, the terminal is configured; and the MAC entity sends the generated MAC PDU to the physical layer entity. According to the technical scheme of the invention, the blind detection complexity of a network side can be reduced, and the processing complexity of uplink control signaling multiplexing of the terminal in an uplink data channel can be reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a protocol data unit generation method, configuration method, device and electronic equipment. Background technique [0002] When the uplink data channel (PUSCH) of the terminal enables the uplink transmission skipping (UL skipping) function and there is no data transmission to be transmitted in the terminal data memory, even if the base station schedules the terminal for data transmission, the UL skipping function allows the terminal to ignore the base station Scheduling without uplink transmission. However, in the above cases, when there is a resource conflict between the uplink control channel (PUCCH) and the dynamically scheduled uplink data channel, the terminal may choose: 1. Do not generate PUSCH, and transmit uplink control information (UCI) on PUCCH; 2. Generate PUSCH , the uplink control information (UCI) is multiplexed and transmitted on the gen...
