Abstract:
1. An apparatus for use in processing data in a user equipment radio receiver, the radio receiver comprising a modem used for wireless communication with a telecommunications network, the 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: receive at the radio receiver, via the modem, first data associated with the wireless communication conducted via the modem, the first data being defined in a first domain and comprises Hybrid Automatic Repeat reQuest (HARQ) transmission data associated with the wireless communication conducted via the modem; transform the first data from the first domain into a second domain using a transform function to generate first transformed data in the second domain; compress the first transformed data in the second domain to produce first compressed data in the second domain; store, in memory in the radio receiver, the first compressed data; receive, via the modem, at least second data associated with the wireless communication conducted via the modem, the at least second data being defined in the first domain and being different than the first data; transform the at least second data from the first domain into the second domain using the transform function to generate at least second transformed data in the second domain; compress the at least second transformed data in the second domain to produce at least second compressed data in the second domain; and combine the at least second compressed data in the second domain with the first compressed data in the second domain stored in the memory of the radio receiver to thereby reduce an amount of data that needs to be stored in the memory of the radio receiver, wherein: the transform function is a linear transform function, the at least second data comprises HARQ re-transmission data associated with the wireless communication conducted via the modem, and the second compressed data in the second domain is combined with the first compressed data in the second domain using a HARQ combining operation.
