A method performed by a WTRU may comprise receiving a beamformed physical control channel using a first beamformed pilot signal. The beamformed physical control channel may include an indication of a beam for a physical shared channel. The indicated beam of the physical shared channel and a beam of the beamformed physical control channel may be different. The method may further comprise receiving, based on the indicated beam, the physical shared channel using a second beamformed pilot signal. In an embodiment, the WTRU may receive an RRC message including an indication of a code of the first beamformed pilot signal.

Reference signal communication in a wireless network

A wireless transmit/receive unit (WTRU) may receive a radio resource control (RRC) message providing configuration information for a physical control channel. The WTRU may monitor the physical control channel using a pilot signal of the physical control channel. The pilot signal may be derived from the pilot sequence and an index of the physical control channel.

Representative methods, apparatus and systems to adjust Do Not Disturb (DND) levels in a wireless transmit/receive unit (WTRU) are disclosed. One representative method includes determining, by the WTRU, that a user of the WTRU is participating or is going to participate in a meeting; obtaining, by the WTRU, organizational hierarchy information; determining a priority associated with one or more meeting participants based on the organizational hierarchy information; and adjusting, without user input, a DND level of the WTRU based on the determined priority.

Methods, apparatus and systems for adjusting do-not-disturb (DND) levels based on callers and meeting attendees

Systems, methods, and instrumentalities are disclosed for a wireless transmit/receive unit (WTRU) to determine rank, offset, or inter-stream interference control information, for example, which may be associated with uplink MIMO operations. A method to control a WTRU may include receiving a special E-RNTI that is associated with a channel. The channel may be associated with a rank indication. The channel may be an E-AGCH-like channel. The channel may have a similar encoding structure as an E-AGCH. The channel may be an E-ROCH. The channel may be received, and it may be determined that the channel is associated with the special E-RNTI. At least one of a rank or an offset may be determined, and the WTRU may be configured with the determined rank or offset. An inter-stream interference (ISI) offset may be received, for example, via RRC signaling, and may be applied to an uplink transmission of a primary stream.
