Abstract: Methods and apparatus for millimeter wave (mmW) beam acquisition are disclosed. An apparatus includes a transmitter configured to transmit millimeter wave (mmW) WTRU (mmW WTRU) information over a cellular system to a base station a receiver and a processor. The receiver receives a list of candidate mmW base stations (mB) including mmW acquisition start timing information from the base station, and the processor calculates correlation values around the received mmW acquisition start timing information for the mBs in the list.

Abstract: Methods and apparatus for changing cell range coverage are disclosed. The coverage may be changed on a per-sub-frame basis. An antenna beam elevation tilting angle may be adjusted to provide different effective downlink (DL) coverage. For example, a subframe may be a small tilt subframe or a large tilt subframe. A network or evolved NodeB (eNB) may determine data channel transmission power to adjust cell range per subframe. Low Power Subframe (LPS) may be used alone or with Almost Blank Subframe (ABS) to transmit data. Timing Advance (TA) handling for uplink (UL) transmissions is described. A common TA (CTA) may be determined for multi-site UL signaling. UL power control may be determined for UL transmission to multiple sites. Radio Link Monitoring (RLM) may be performed for multiple sites on a carrier frequency. A wireless transmit/receive unit (WTRU) may maintain synchronization in selected subframes for multiple cells.

Abstract translation: 公开了改变单元范围覆盖的方法和装置。 可以在每个子帧的基础上改变覆盖。 可以调整天线波束仰角倾斜角度以提供不同的有效下行链路（DL）覆盖。 例如，子帧可以是小倾斜子帧或大倾斜子帧。 网络或演进的节点B（eNB）可以确定数据信道传输功率以调整每子帧的小区范围。 低功率子帧（LPS）可以单独使用或与几乎空白子帧（ABS）一起使用来传输数据。 描述了用于上行链路（UL）传输的定时提前（TA）处理。 可以为多站点UL信令确定公共TA（CTA）。 UL功率控制可以被确定用于UL传输到多个站点。 可以对载波频率上的多个站点执行无线电链路监视（RLM）。 无线发射/接收单元（WTRU）可以在多个小区的选定子帧中保持同步。

Abstract: Methods and apparatus for changing cell range coverage are disclosed. A wireless transmit/receive unit (WTRU) may include circuitry configured to transmit subframes of radio frames using a physical uplink shared channel (PUSCH), where the subframes are divided into first and second sets. The circuitry may include a first power control loop utilized for the first set of subframes and a second power control loop utilized for the second set of subframes. The first power control loop may set transmission power levels for transmission over the PUSCH for the first set of subframes, and the second power control loop may set transmission power levels for transmission over the PUSCH for the second set of subframes. The circuitry may be configured with a first physical uplink control channel (PUCCH) for a first eNodeB and a second PUCCH for a second eNodeB to simultaneously communicate with the first and the second eNodeBs.
