Space Frequency block coding for PUCCH

摘要

Apparatus including at least one processor and at least one memory including computer program code the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: determining at least one control symbol and at least one channel from a channel set for an at least one control symbol representing the at least one control signal for at least one output port; and determining at least one further control symbol and at least one further channel from the channel set for the at least one further control symbol for at least one further output port, wherein the at least one further control symbol and the at least one further channel is dependent on the at least one control symbol and the at least one channel.

主权项

1. A method comprising:
determining at least one control symbol and at least one channel from a channel set for the at least one control symbol representing at least one control signal for at least one port; and determining at least one further control symbol and at least one further channel from the channel set for the at least one further control symbol for at least one further port, wherein determining at least one further control symbol and at least one further channel comprises: receiving an indicator of the at least one channel; and mapping the indicator to determine the at least one further channel for the at least one further control symbol, wherein the indicator comprises a vector having a first number of elements, the first number of elements being the number of associated channels, each element representing an indication of the symbol selected to be output on the channel associated with the element, and wherein mapping the indicator comprises applying a mathematical function to said first number of elements to obtain an identical number of elements for a second vector for the at least one further control symbol and the at least one further channel.
