A reference signal, RS, is generated in a wireless communication system based on a starting position, in the frequency domain, of the RS and a transmission channel bandwidth of the RS. At least one of the starting position of the RS and the bandwidth allocated to a transmission channel for the RS is/are ascertained. A base sequence index, BSI, is then derived by mapping at least one ascertained of the RS starting position and transmission channel bandwidth (12) according to a predefined mapping rule (14) to the BSI (16). The RS is determined based on the derived BSI. |

1. A computer-based method performed by a controller circuit of a transmitter for generating a reference signal (RS) in a wireless communication system, comprising:
ascertaining, by an ascertainer circuit of the controller circuit in the transmitter, a starting position, in the frequency domain, of the RS, and a transmission channel bandwidth for the RS; deriving, by a base sequence index (BSI) deriver circuit of the controller circuit, the BSI deriver circuit being operationally coupled to the ascertainer circuit, a BSI by mapping the starting position and the transmission channel bandwidth according to a predefined mapping rule to the BSI, wherein the predefined mapping rule maps a combination of a starting resource block (RB) index for a physical uplink channel and a bandwidth of the physical uplink channel to a group index, the predefined mapping rule constrained by a number of available group indexes; determining, by an RS determiner circuit of the controller circuit, the RS determiner circuit being operationally coupled to the BSI deriver circuit, the RS based on the derived BSI; and wherein the determined RS is transmitted from the transmitter to a receiver in the wireless communication system. |
