METHODS, SYSTEMS AND DEVICES FOR DECOUPLED INTERFERENCE RANDOMIZATION FOR UPLINK REFERENCE SIGNALS

摘要

Interference between reference signals from user equipments in a wireless network, the method may be reduced by using a received time shift value from a node in the wireless network. An interference randomization technique may be applied to a reference signal and a sequence may be generated based on the reference signal to which the interference randomization technique has been applied. A processed reference signal may be derived by applying a time shift based on the time shift value to the sequence. The processed reference signal may be transmitted to the node. Related systems, methods, nodes and wireless devices are also described.

1. A node of a wireless communication network comprising:
a wireless transceiver; and a processor that is configured to perform operations comprising: determining a time shift to be applied by a user equipment to a sequence generated based on applying an interference randomization technique to a reference signal; and communicating from the node the time shift that was determined to the user equipment.
