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.

Abstract: Splitting data in a wireless communications network. Data may be split to use multiple base stations for transmission to user equipment in order to improve the bandwith if a UE is on a cell edge, or may be split by user equipment for transmission to multiple base stations in order to improve handover. Data splitting may be performed at the Packet Data Convergence Protocol layer, at the Radio Link Control layer, or at the Media Access Control layer on user equipment or on a base station. Data may instead be split in a network node, such as in a serving gateway, in order to reduce X2 interface load or delay carrier aggregation.

While maintaining a connection with a component carrier on the source eNode-B, the WTRU may establish a connection with another component carrier on a target eNode-B.

Abstract: A method and apparatus are described. A wireless transmit/receive unit (WTRU) includes circuitry that determines transmission power levels associated with physical uplink shared channel (PUSCH) transmissions over a plurality of uplink component carriers. On a condition that maximum power scaling is required, the circuitry prioritizes providing power to a physical uplink control channel (PUCCH) over providing power to a physical uplink shared channel (PUSCH) having uplink control information (UCI) and prioritize providing power to the PUCCH and PUSCH having UCI over a PUSCH not having UCI. The circuitry transmits the PUCCH, the PUSCH having UCI or at least one PUSCH not having UCI over the plurality of uplink component carriers.

Abstract: A method, apparatus and system for wireless communication are described. The method includes transmitting and receiving data to and from one or more wireless transmit/receive units (WTRUs) via an underlay system access link. The underlay system is non-standalone, and control information is provided from an overlay system. An underlay base station is linked to other underlay base stations to implement a mesh backhaul. The method also includes transmitting and receiving at least a portion of the data to or from an overlay base station via backhaul links and receiving control data from the overlay base station.

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: Methods and apparatus for local data caching are disclosed. Data may be stored in a local data storage connected to a base station or network nodes. The data flow may be split. The base station may coordinate with a cooperating base station for split-data transmission of locally cached data. Data may be split at different layers.

Abstract: Methods, program products, and systems for checkpoint based progressive backup are described. When a system receives a request to update a page of a storage device storing database files of a database, the system can update the page and replicate the updated page in a shadow page in a backup queue. The backup queue can store multiple shadow pages, where each updated page can correspond to at most a specified number of shadow pages in the queue. Each shadow page can be associated with a timestamp of a latest update. At pre-specified temporal checkpoints, the system can write the shadow pages in the queue to a backup file in the order of the timestamps. Upon receiving a restoration request, the system can restore the database to a state as of the time of the checkpoint using the backup file.

Abstract: Methods and apparatus are described for compressing channel state information (CSI) in time-domain based on path location information for CSI feedback. Downlink (DL) CSI is compressed in the time domain and fed back by not sending the multipath location information, or sending at a very low rate. In one method, a wireless transmit/receive unit (WTRU) selects the strongest multipath components based on channel characteristics. The multipath components are quantized in the time domain via direct or vector based quantization. The base station reconstructs a channel impulse response from the fed back quantized multipath components and applies same to precoding processing. In another method, the WTRU feeds back information associated with a narrowband portion(s) of a system spectrum. The selected narrowband portion(s) have sufficient density over time to allow good precoding per subband or across the system spectrum. Short term feedback may be augmented with long term channel information.

Abstract: A wireless communication network and method are described for enhancing cell-edge performance of a wireless transmit/receive unit (WTRU). The WTRU may establish a connection with a plurality of sites via respective downlinks (DLs). Each DL may include at least one DL component carrier (CC) that operates on a frequency that is the same or different than one or more of the other CCs. The sites may manipulate their transmit power for a particular CC operating frequency such that the distance from a particular one of the sites to its cell boundary may become larger by increasing its transmit power on the particular frequency, and the distance from at least one of the other sites to its respective cell boundary may become smaller by decreasing its transmit power on the particular frequency. Thus, a coverage overlap between different CC frequencies may be created while maintaining a frequency reuse pattern of one.

Abstract: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

Abstract: An electronic type substrate having 40 to 97 weight-percent polymer and 3 to 60 weight-percent auto-catalytic crystalline filler. An interconnect or a conductor trace is created in the substrate by: i. drilling or ablating with a high energy electromagnetic source, such as a laser, thereby selectively activating the multi cation crystal filler along the surface created by the drilling or ablating step; and ii. metalizing by electroless and/or electrolytic plating into the drilled or ablated portion of the substrate, where the metal layer is formed in a contacting relationship with the activated multi cation crystal filler at the interconnect boundary without a need for a separate metallization seed layer or pre-dip.

Abstract: Method and apparatus are disclosed for calculating a target connection frame number (CFN) for a data frame in wireless communications. An update to an offset between the CFN and a radio access network frame number is computed. A target CFN variable is incremented in response to a received timer signal. The value of an update variable is checked to determine whether a new value of the offset has been received since a previous update to the offset. A new target CFN is calculated using a current target CFN and the new value of the offset on a condition that the new value of the offset has been received. The current target CFN is set equal to the new target CFN.
