摘要： Systems, methods, and apparatuses for using band-limited subframes in wireless communication networks are provided. During the band-limited subframes, the macro cell base station may mute its transmission or transmit at a low power over some frequency sub-band, while transmitting at a normal or higher power over other frequency sub-band. Correspondingly, the small cell base station may communicate with UEs within its coverage at the frequency sub-band that the macro cell base station transmits at a low power. The band-limited subframe enables the small cell base station to communicate with the UE with reduced interference, and in the meantime, increases the throughput of macro cell base station as it does not require the macro cell base station to completely mute its transmission during the band-limited subframe.

摘要： Methods and systems disclosed herein can help to dynamically adjust page transmission power, and in particular, the transmission power for quick paging bits, depending upon whether a user equipment (UE) is operating as a single radio LTE (SRLTE) device. An exemplary method involves an access network making a determination that a UE is configured to use a single radio system for (a) data communication under a first air interface protocol, and (b) voice calls under a second air interface protocol; and responsively initiating a process to set a transmission power used to page the first UE for a voice call under the second air interface protocol to a higher power level, as compared to a transmission power level utilized to page a second UE configured to use separate radio systems for data communication under the first air interface protocol and voice calls under the second air interface protocol.

摘要： Systems and methods for maintaining an IP (Internet protocol) connection in a mobile network are disclosed. Techniques are disclosed wherein an optimal keep-alive interval is determined, and dynamic adjustments of keep-alive message interval are employed to prevent detection and counter measure. Keep-Alive schedule information may be determined at a first mobile terminal for a network, and subsequently used for a second mobile terminal when the second mobile terminal encounters that same network. In some embodiments, the Keep-Alive schedule information is stored at a network-node device. In some embodiments, the first mobile terminal and the second mobile terminal are cellular phones.

摘要： The present invention is designed to allow user terminals to detect small cells in the off state efficiently when the small cells are switched on and off dynamically. A radio base station that switches between a continuous transmission state and a discontinuous transmission state dynamically, has a power control section that executes power control so that the transmission power of a reference signal for cell detection that is transmitted in the discontinuous transmission state is lower than the transmission power of a reference signal that is transmitted in the continuous transmission state.

摘要： A method and apparatus for a wireless receiver are described herein. A user equipment (UE) may process control information in a first time slot of a transmission time interval (TTI) having a plurality of time slots. The UE may, in response to the control information including valid resource assignment information for the UE, receive data in the first time slot and another time slot of the TTI. The UE may, in response to the control information not including valid resource assignment information for the UE, discontinue reception in the TTI. The UE may discontinue reception for another time slot of the TTI. The circuitry may be further configured to receive a transmission indicating that a base station will discontinuously transmit to the UE. The control information may be processed prior to processing any of the data symbols of the TTI.

摘要： Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or “blanking,” of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits. Provisions are nevertheless made for the transmission of certain designated as “critical” by, e.g., a vocoder. The receiver detects the presence of null rate or non-null rate transmissions and processes the received frames accordingly, including updating an outer loop power control only in response to non-null rate frames. Further techniques for changing the pilot transmission gating pattern to assist the receiver in detecting null rate frames are provided. In another aspect, early termination of a signal transmission over a wireless communications link is provided. In an exemplary embodiment, a base station (BS) transmits power control groups (PCG's) for a frame over a forward link (FL) to a mobile station (MS) until accurate reception of the frame is acknowledged by the MS over a reverse link (RL), possibly before all PCG's of the frame are received over the FL. Possible ACK signaling methods are defined for channels associated with a cdma2000 wireless communications system. In another exemplary embodiment, techniques for reverse link early termination are also provided.
