Abstract

The present invention relates to devices and methods for transmitting a data packet in a communication network. The invention relates to a transmitter (601) for transmitting a data packet, in particular according to a hybrid automatic repeat request (HARQ) scheme or blind repetition scheme, to a receiver (631). The transmitter (601) comprises a communication interface (603) for transmitting the data packet and a processor (605) that is configured to determine a first transmission multiplexing scheme for transmitting the data packet in a first transmission, and determine a second transmission multiplexing scheme for transmitting the data packet in a second transmission, wherein the first transmission multiplexing scheme is associated with a higher block error rate than the second transmission multiplexing scheme and the first transmission is timely separated from the second transmission.

Description

technical field [0001] The present invention relates generally to mobile communications. More specifically, the invention relates to transmitters and receivers and corresponding methods for sending data packets in a mobile communication network. Background technique [0002] Ultra-reliable low latency communication (uRLLC) is one of the key requirements for 5G new radio (NR) technology used in vehicle communication, industrial automation, etc., such as figure 1 The table shows that in these applications, the transmission of small data requires a low delay of 1ms and a very high reliability of 99.999%. [0003] Spectrum-inefficient low modulation and coding rates are critical to meet the challenging uRLLC reliability requirements, which ultimately require more bandwidth, thus limiting user equipment (UE) per cell uRLLC connection. Meeting uRLLC requirements at high cell loads is a challenging task due to increased queuing delays, where the total delay includes queuing dela...
