1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to perform:
transmitting a preconfigured number of transmissions of a first data with hybrid automatic repeat requests consecutively without waiting between the transmissions for response to any of the requests, wherein the preconfigured number is an integer and greater than one;
transmitting, while waiting for response to the requests transmitted with the first data, the preconfigured number of consecutive transmissions of further data; and
reusing at least one hybrid automatic repeat request identifier, which was used with at least one of the requests transmitted with the first data, with the transmissions of the further data, wherein the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus further to perform prior to transmitting:
estimating radio frequency conditions;
determining, based on the radio frequency conditions estimated, the preconfigured number amongst two or more preconfigured numbers, which are integers and at least one of the two or more preconfigured numbers is greater than one, wherein the two or more preconfigured numbers are associated with respective two or more target block error rates, a preconfigured number with a target block error rate; and
using the preconfigured number determined and an associated target block error rate for the transmissions with the hybrid automatic repeat requests in order to make hybrid automatic repeat request identifier reuse transparent to a receiving entity.
