Abstract
Methods and apparatuses are provided that facilitate generating sequences for transmitting reference signals (RS) based at least in part on a cell identifier or other parameters common for a plurality of cells. Where the plurality of cells provide similar joint uplink resources to a device in multi-user multiple-input multiple-output (MIMO), the device can transmit a signal to the plurality of cells over the joint uplink resources. For RSs transmitted according to a sequence generated based on a cell specific identifier or other parameters, the device can utilize a cell identifier, or other parameters, common to the plurality of cells such that the plurality of cells can all decode the RSs. In this regard as well, the plurality of cells can each receive or generate the common cell identifier or other parameters to properly decode the RSs.
