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

Claim 0:
1. A communication method, comprising:
obtaining, by a first device, transmission states of n data packets by using a first protocol layer entity, wherein the first protocol layer entity comprises a radio link control (RLC) layer entity or an entity above an RLC layer;
starting, by the first device, a timer based on the transmission states of m data packets in the n data packets being transmission failures, wherein n and m are both positive integers, and m is less than or equal to n; and
based on the first device determining that q data packets fail to be transmitted within a preset time period during running of the timer, adjusting, by the first device, a radio resource configuration parameter for transmitting a subsequent data packet, wherein the subsequent data packet is transmitted after the qth data packet that failed to be transmitted within the preset time period, and q is a positive integer greater than 0;
wherein adjusting the radio resource configuration parameter comprises at least one of the following:
adjusting a modulation and coding scheme (MCS);
increasing a quantity of retransmissions of a hybrid automatic repeat request (HARQ);
increasing a quantity of retransmissions of an automatic repeat request (ARQ);
increasing a size of a transmission resource;
adjusting a type of a transmission resource;
increasing a priority of a logical channel;
adjusting an RLC layer transmission mode of a radio bearer;
adjusting a radio bearer to use duplication transmission; or
increasing a transmit power.
