    Abstract: In High-Speed Downlink Packet Access (HSDPA) communications in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system (called TD-HSDPA), the payload of two High-Speed Shared Information Channels (HS-SICHs) may be bundled into one HS-SICH channel by reusing the unused uplink synchronization shift (SS) for power control purposes. Thus, the HS-SICH spreading factor (SF) 16 code channel overhead may be reduced by 50%.

    Abstract: Methods, devices, and systems embodiments enable recovering from an out-of-service state in a wireless device. A processor may perform scans of first and second acquisition databases to acquire a first renewed service connection for a first subscriber identification module (SIM). The scans include first and second searches for first channels identified in first and second technology lists, respectively, from the first and second acquisition database, respectively, until either a renewed service connection is acquired or each of the first and second technology lists are exhausted. The first and second technology lists identify channels from a most recently used radio access technology of the respective acquisition databases. The processor may perform a full frequency scan to acquire a first renewed service connection for the first SIM in response to determining that each of the first and second technology lists were exhausted.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an interference type between a time division duplex (TDD) configuration subframe of a serving cell and a corresponding TDD configuration subframe of a neighboring cell, and sets a transmit power for an apparatus in the serving cell based on the interference type. The apparatus in the serving cell may be a user equipment (UE), in which case the apparatus applies a set of uplink (UL) open loop power control parameters for the UE. The apparatus in the serving cell may be a base station (eNB), in which case a DL transmit power is set for the eNB. Depending on the interference type, the DL transmit power may be a fixed, full power DL transmission or an adjusted DL transmission.

    Abstract: A method, a computer program product, and an apparatus for separating a cell cluster to two or more cell clusters are provided. The cell cluster may be separated into two or more cell clusters in order to mitigate interference between cells while allowing for TDD subframe configuration flexibility. The method identifies at least one separating cell in a cell cluster, the cell cluster including at least two cells having a common TDD subframe configuration, where a coupling loss between one cell in the cell cluster and at least another cell in the cell cluster is lower than a predefined threshold. The method separates the cell cluster based on the at least one separating cell into at least a first cell cluster and a second cell cluster and sets a first TDD subframe configuration for the first cell cluster and a second TDD subframe configuration for the second cell cluster.

    Abstract: Certain aspects of the present disclosure propose techniques for power control for high-efficiency scheduling for Time Division Synchronous Code Division Multiple Access (TD-SCDMA) High Speed Uplink Packet Access (HSUPA). The basic principle of this power control for a scheduled Enhanced Dedicated Channel (E-DCH) Physical Uplink Channel (E-PUCH) is that all information for a transport block size (TBS) decision is made available at a user equipment (UE). Certain aspects provide a method for wireless communications. The method generally includes receiving, from a UE, an uplink signal, determining a reference uplink power level based on a filtered interference power of the received signal, and transmitting an indication of the reference uplink power level to the UE.
