Abstract
Different sequence resources can be allocated to a mobile device where the mobile device can exclusively uses the sequence resource with regard to a base station during a communication session. However, if another mobile device using another base station is assigned a matching sequence resource, then there can be interference if the mobile devices are relatively close enough together. Therefore, randomization of the sequence resources can take place—moreover, a cyclic shift result can be employed in sequence resource allocation to attempt to minimize interference.
