Abstract:
1. In a communication system wherein a Base Station (BS) communicates with User Equipments (UEs) transmitting data signals or control signals and multiple Reference Signals (RSs) in a Physical Uplink Shared CHannel (PUSCH) over a Transmission Time Interval (TTI), with the multiple RSs represented by respective multiple first sequences, or transmitting multiple control signals and multiple RSs in a Physical Uplink Control CHannel (PUCCH) over the TTI, with the multiple control signals or the multiple RSs represented by respective multiple second sequences, a method for a UE to select the multiple first sequences and the multiple second sequences, the method comprising the steps of: receiving, by the UE, a first “sequence hopping” parameter and a second “sequence hopping” parameter; determining, by the UE, all of the multiple first sequences to be a first sequence and all of the multiple second sequences to be a second sequence if the first “sequence hopping” parameter indicates that sequence hopping is not enabled; determining, by the UE, all of the multiple first sequences to be a first sequence and the multiple second sequences from a set of second sequences according to a second hopping pattern if the first “sequence hopping” parameter indicates that sequence hopping is enabled and the second “sequence hopping” parameter indicates that sequence hopping is not enabled; and determining, by the UE, the multiple first sequences from a set of first sequences according to a first hopping pattern and the multiple second sequences determined from a set of second sequences according to a second hopping pattern if the first “sequence hopping” parameter indicates that sequence hopping is enabled and the second “sequence hopping” parameter indicates that sequence hopping is enabled, wherein the first “sequence hopping” parameter is transmitted by broadcast signaling to all UEs and the second “sequence hopping” parameter is transmitted by the UE-specific signaling to an individual UE separately from the other UEs.
