Supplementary uplink carrier configuration method and device, and scheduling resource allocation method and device

A method for allocating a scheduled resource, the method comprising:

• receiving a supplementary uplink (SUL) related parameter from a base station, the SUL related parameter being configured to define, in a restricted cell where logical channel prioritization (LCP) restriction is made with respect to SUL and non-SUL carriers, whether an uplink resource allocated to a logical channel is an SUL carrier resource or a non-SUL carrier resource;
• and
• allocating, according to the SUL related parameter, a scheduled resource corresponding to uplink scheduling information to a logical channel of a carrier corresponding to the uplink scheduling information;
• wherein the SUL related parameter is generated according to a generation rule, the generation rule comprising:
• configuring a primary logical channel of two logical channels with a packet data convergence protocol (PDCP) duplication function enabled to use the SUL carrier resource in the restricted cell, and configuring a secondary logical channel of the two logical channels with the PDCP duplication function enabled to use the non-SUL carrier resource in the restricted cell;
• or
• configuring the primary logical channel of the two logical channels with the PDCP duplication function enabled to use the non-SUL carrier resource in the restricted cell, and configuring the secondary logical channel of the two logical channels with the PDCP duplication function enabled to use the SUL carrier resource in the restricted cell.

A device for configuring a supplementary uplink (SUL) carrier, the device comprising:

• a processor;
• and
• a memory storing instructions executable by the processor;
• wherein the processor is configured to:
• generate an SUL related parameter, the SUL related parameter being configured to define, in a restricted cell where logical channel prioritization (LCP) restriction is made with respect to SUL and non-SUL carriers, whether an uplink resource allocated to a logical channel is an SUL carrier resource or a non-SUL carrier resource;
• and
• transmit the SUL related parameter to user equipment (UE);
• wherein generating the SUL related para meter comprises generating the SUL related parameter according to a generation rule, the generation rule comprising:
• configuring a primary logical channel of two logical channels with a packet data convergence protocol (PDCP) duplication function enabled to use the SUL carrier resource in the restricted cell, and configuring a secondary logical channel of the two logical channels with the PDCP duplication function enabled to use the non-SUL carrier resource in the restricted cell;
• or
• configuring the primary logical channel of the two logical channels with the PDCP duplication function enabled to use the non-SUL carrier resource in the restricted cell, and configuring the secondary logical channel of the two logical channels with the PDCP duplication function enabled to use the SUL carrier resource in the restricted cell.
