Methods and apparatus for vertical beamforming

Abstract

A method and apparatus for determining a vertical beam for reception are disclosed herein. A method in a wireless transmit/receive unit (WTRU) includes receiving a broadcast message from an evolved Node B (eNB) that includes information associated with a plurality of vertical beams wherein the information includes at least one set of Physical Random Access Control Channel (PRACH) resources associated with each of the plurality of vertical beams measuring reference signals transmitted on each of the plurality of vertical beams to select a reception vertical beam transmitting a PRACH preamble in a set of resources associated with the selected reception vertical beam and receiving communications from the eNB using the selected reception vertical beam.

11. The WTRU of claim 7, wherein the WTRU selects a reception vertical beam based on predetermined criteria

12. The WTRU of claim 7, wherein the at least one set of PRACH resources is portioned based on the number of the plurality of vertical beams

13. A method for determining a vertical beam for reception in an evolved Node B (eNB), the method comprising:', 'transmitting a broadcast message to a wireless transmit/receive unit (WTRU) that includes information associated with a plurality of vertical beams, wherein the information includes at least one set of Physical Random Access Control Channel (PRACH) resources associated with each of the plurality of vertical beams;', 'receiving a PRACH preamble in a set of resources associated with a selected reception vertical beam, wherein the selected reception vertical beam is determined by the WTRU based on measured reference signals transmitted on each of the plurality of vertical beams; and', 'transmitting communications to the WTRU using the selected reception vertical beam

14. The method of claim 13, wherein the information associated with the plurality of vertical beams includes a plurality of measurement configurations

15. The method of claim 13, wherein the PRACH preamble is transmitted on an allocated frequency associated with the set of resources

16. The method of claim 13, wherein the selection of a reception vertical beam is based on a determination that the measured reference signal is better on at least one vertical beam

17. The method of claim 13, wherein the selecting of a reception vertical beam is based on predetermined criteria

18. The method of claim 1, wherein the at least one set of PRACH resources is portioned based on the number of the plurality of vertical beams

19. A method for determining a vertical beam for transmission in an evolved Node B (eNB), the method comprising:', 'transmitting a broadcast message to a wireless transmit/receive unit (WTRU) that includes two or more Channel State Information - Reference Signal (CSI-RS) configurations;', 'receiving a first measurement report from the WTRU including a received signal-to-interference plus noise ratio (SINR) for a cell-specific CSI- RS in an uplink subframe;', 'receiving a second measurement report from the WTRU including SINR for each antenna port in the cell-specific CSI-RS associated with a vertical beam; and', 'transmitting communications to the WTRU using vertical beam.']
