Abstract: A method and apparatus are disclosed for demodulating a NR-PBCH signal. The method may comprise receiving a primary SS and an SSS. The received SSS signal may be used as a reference signal to detect demodulation reference signals of the NR-PBCH. These demodulation reference signals may be interleaved with data on the NR-PBCH. In one method, the NR-PBCH DMRS are associated with an SSB index in an effort to improve randomization in the synchronization process. The NR-PBCH payload may be demodulated using the PSS and/or SSS and the DMRS. In one embodiment, the NR-PBCH DMRS may mapped to DMRS REs on a frequency first and time second mapping basis.

Abstract: A system, method, and device for ensuring a number of Phase Tracking Reference Signal(s) (PT-RSs) are the same for multiple slots. A wireless transmit/receive unit (WTRU) may receive control information including a number of scheduled resource blocks (RBs) then determine a PT-RS density based on the number of scheduled RBs. The WTRU may determine a RB offset value for the WTRU based on a WTRU-ID modulo the maximum RB offset value, where the maximum value for the RB offset value may be based on at least one of the number of the scheduled RBs and the PT-RS density. The WTRU may then transmit or receive a signal with PT-RS based on the RB offset value.

Abstract: Methods, apparatus and systems are described for a wireless transmit/receive unit (WTRU) to manage its transmission power. A power headroom report (PHR) may be triggered based on changes to backoff or the impacts of backoff. Additional backoff may be used to calculate a maximum output power of the WTRU and may be indicated by a domination indicator to network resources. The WTRU may be configured to eliminate triggers caused by virtual PHRs. Furthermore, the WTRU may be configured to respond to rapid changes to backoff.

Abstract: A method for performing radio usage measurements to support radio link operations and/or load balancing may be performed at an evolved Node B (eNB). The method may include determining a first radio usage parameter. The first radio usage parameter may be a measurement of radio usage between an eNB and at least one wireless transmit receive unit (WTRU). The method may further include determining a second radio usage parameter. The second radio usage parameter may be a measurement of radio usage between the eNB and at least one relay node (RN) served by the eNB. The method may further include utilizing at least one of the first radio usage parameter or the second radio usage parameter to evaluate at least one of evolved universal terrestrial radio access (E-UTRA) radio link operations, radio resource management (RRM), network operations and maintenance (OAM), and self-organizing networks (SON) functions or functionalities.

Abstract: Power control for devices having multiple transmit antennas are disclosed, including power control methods for Physical Uplink Control Channel (PUCCH) and Sounding Reference Signal (SRS) transmissions for a wireless transmit/receive unit (WTRU). The PUCCH and SRS power control methods include selecting a multiple input multiple output (MIMO) mode and changing the power of the PUCCH or SRS transmission based on the selected MIMO mode. Another power control method estimates an antenna gain imbalance (AGI) for a WTRU having at least two transmit antennas. The AGI is based on measuring a Reference Signal Received Power (RSRP) on each transmit antenna. Each transmit antenna is then scaled by an AGI scaling factor based on the estimated AGI.

Abstract: Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available ( i.e. , active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.
