Patent ID: 11968050
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A base station, comprising:
at least one processor;
a memory;
a communications interface; and
a bus;
wherein the at least one processor, the memory, and the communications interface are connected to and communicate with each other by using the bus;
wherein the communications interface is configured to establish a communication connection to a user equipment; and
wherein the memory is coupled to the at least one processor and stores programming instructions for execution by the at least one processor, and wherein the programming instructions instruct the at least one processor to:
divide a set of all available preamble sequences in a random access process into a plurality of sequence groups, wherein each sequence group of the plurality of sequence groups includes a plurality of preamble sequences, and wherein each preamble sequence in a same sequence group corresponds to a same processing capability level;
receive, from the user equipment, processing capability information of the user equipment based on a preamble sequence used by the user equipment for the random access process, wherein the processing capability information of the user equipment represents a processing capability level of the user equipment corresponding to the preamble sequence used by the user equipment;
send a data packet to the user equipment;
determine a processing capability of the user equipment according to the processing capability information of the user equipment;
determine data information of the data packet;
determine, based on the processing capability and the data information, a second capability of the user equipment to send positive acknowledgement (ACK)/negative acknowledgement (NACK) (ACK/NACK) information corresponding to the data packet; and
determine, based on a first delay and the second capability of the user equipment to send the ACK/NACK information corresponding to the data packet, a first subframe to be used by the user equipment to send the ACK/NACK information corresponding to the data packet, wherein the first delay is an additional delay instructed by the base station to send the ACK/NACK information corresponding to the data packet, and the first delay is determined by the base station based on at least one of a scheduling requirement or a service priority corresponding to the data packet.
