US 9,794,915 B2 · Method for allocating resources to uplink control channel

Abstract

A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.

A method for transmitting uplink control information at a mobile station (MS) in a mobile communication system, the method comprising:

mapping reference signals (RSs) at two or more time domain units, separated from each other in time domain, within one transmission time interval (TTI) of a 2-dimensional time-frequency resource grid;
multiplexing the uplink control information with uplink data based on one or more of time divisional multiplexing (TDM) or frequency divisional multiplexing (FDM) by mapping the uplink control information and the uplink data to the 2-dimensional time-frequency resource grid,
wherein the uplink control information comprises one or more of an ACK/NACK and a CQI, and
wherein the one or more of the ACK/NACK and the CQI are mapped at each of time domain units respectively adherent to each of the two or more time domain units in which the RSs are mapped within the one TTI;
and
transmitting the RSs, the uplink control information and the uplink data mapped to the 2-dimensional time-frequency resource grid to a base station.
