Uplink transmission method and device

An uplink transmission method, comprising:

• creating one or more Uplink (UL) grants, each UL grant being to schedule one or more User Equipments (UEs) to perform uplink transmission in a target time unit;
• and
• transmitting the UL grants on a target time-domain resource and a target frequency-domain resource in a first time unit, the time unit having a predefined length of B1 subframes or B2 symbols, where B1 and B2 are each an integer greater than or equal to 1;
• wherein the uplink transmission method further comprises performing interference measurement on a UE in accordance with a second predetermined sequence, the second predetermined sequence is related to an identifier of the UE, and the second predetermined sequence is carried when the uplink transmission is performed on a time-domain resource and a frequency-domain resource scheduled in the target time unit.

An uplink transmission device, comprising a processor, and a memory connected to the processor via a bus interface and configured to store therein programs and data for the operation of the processor, wherein the processor is configured to call and execute the programs and data stored in the memory, to achieve functions of:

• a detection module configured to detect an Uplink (UL) grant on a target time-domain resource and a target frequency-domain resource in a first time unit, the UL grant being to schedule one or more User Equipments (UEs) to perform uplink transmission in a target time unit, a time unit having a predefined length of B1 subframes or B2 symbols, where B1 and B2 are each an integer greater than or equal to 1;
• an acquisition module configured to acquire scheduling information for the UE in the target time unit from the UL grant;
• and
• an uploading module configured to perform the uplink transmission on a time-domain resource and a frequency-domain resource scheduled in the target time unit in accordance with the scheduling information;
• wherein the processor is further configured to achieve function of:
• an interference measurement module configured to carry a predetermined sequence when performing the uplink transmission on the time-domain resource and the frequency-domain resource scheduled in the target time unit, the other UE(s) and/or base station(s) is capable of performing interference measurement on the UE in accordance with the predetermined sequence, wherein the predetermined sequence is related to an identifier of the UE.

An uplink transmission device, comprising a processor, and a memory connected to the processor via a bus interface and configured to store therein programs and data for the operation of the processor, wherein the processor is configured to call and execute the programs and data stored in the memory, so as to achieve functions of:

• a creation module configured to create one or more UL grants, each UL grant being to schedule one or more UEs to perform uplink transmission in a target time unit;
• and
• an UL grant transmission module configured to transmit the UL grants on a target time-domain resource and a target frequency-domain resource in a first time unit, the time unit having a predefined length of B1 subframes or B2 symbols, where B1 and B2 are each an integer greater than or equal to 1;
• wherein the processor is further configured to achieve function of:
• an interference measurement module configured to perform interference measurement on a UE in accordance with a predetermined sequence, the predetermined sequence is related to an identifier of the UE, and the predetermined sequence is carried when the uplink transmission is performed on a time-domain resource and a frequency-domain resource scheduled in the target time unit.
