Communication Mechanism Using Demodulation Reference Signal Based Communication Mode

摘要

There is provided a mechanism for conducting a communication between at least one communication network control element such as an eNB and at least one communication element such as a UE wherein a DM RS based communication mode is used. DMRS (scrambling) sequences are generated wherein each DMRS sequence includes a set of calculation parameters being specific for the respective DMRS sequence, wherein the set of calculation parameters is configurable by the eNB during communication. For initializing each of the at least one scrambling sequence before receiving the configuration information, i.e. in an initial phase of the communication, a predetermined default value based on e.g. an UE_ID and being selectable from a set of predetermined default values is used for the set of calculation parameters in each DMRS sequence.

1. An apparatus comprising:
at least one processor; and at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus to perform at least the following: to conduct with at least one communication network control element a communication by using a demodulation reference signal based communication mode for signals received from the at least one communication network control element; and to generate in the demodulation reference signal based communication mode at least one predefined scrambling sequence of a demodulation reference signal, wherein each of the at least one scrambling sequence comprises a set of calculation parameters being specific for the respective scrambling sequence, wherein the set of calculation parameters is configurable during the at least one communication on the basis of configuration information received from the at least one communication network control element; and to select, for initializing each of the at least one scrambling sequence before receiving the configuration information, at least one predetermined default value selectable from a set of predetermined default values for the set of calculation parameters in each of the at least one scrambling sequence.
