    Abstract: Techniques for managing operation on a communication medium shared between Radio Access Technologies (RATs) are disclosed. The management may comprise, for example, monitoring the medium for first RAT signaling in accordance with a first RAT; determining a utilization metric associated with utilization of the medium by the first RAT signaling; cycling operation in accordance with a second RAT between activated periods and deactivated periods of communication over the medium in accordance with a Time Division Multiple Access (TDM) communication pattern based on the utilization metric; and periodically disabling the cycling to provide an AOS period of activated communication over the medium for operation in accordance with the second RAT, with the AOS period being longer than an individual activated period of the TDM communication pattern. The management may also comprise, for example, techniques for enabling/disabling monitoring by an access terminal in accordance with the TDM communication pattern.

    Abstract: Systems and methods for adaptively using subframes for radar detection in unlicensed spectrum are disclosed. The systems and methods include scheduling a first set of subframes in a frame duration for traffic based at least in part on a first configuration for communications in an unlicensed frequency band. Further, the systems and methods include scheduling, based at least in part on the first configuration, a second set of subframes in the frame duration for detection of a primary user of the unlicensed frequency band. Moreover, the systems and methods include adjusting a number of subframes in the first and second set of subframes based on a second configuration for communications, wherein the second configuration for communications is identified based on a type of primary user being detected.

    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.

    Abstract: Device antennas may be allocated such that a non-LTE module (e.g., GSM module or 1x module) shares the same antenna with an LTE DRx module. This may lead to degradation of a non-LTE voice service when the LTE DRx module performs LTE transmit antenna selection causing the non-LTE module to be switched to a different antenna during reception/transmission of voice slots, resulting in a loss of slots. Accordingly, a method, an apparatus, and a computer program product for controlling antenna switching are provided. The apparatus facilitates a first radio module to use a first antenna for performing a first operation, detects that a second radio module will attempt to use the first antenna during transmit antenna selection for performing a second operation, and determines whether to switch use of the first antenna from the first radio module to the second radio module based on a type of the first operation.

    Abstract: Techniques to increase the capacity of a W-CDMA wireless communications system. In an exemplary embodiment, early termination of one or more transport channels on a W-CDMA wireless communications link is provided. In particular, early decoding is performed on slots as they are received over the air, and techniques are described for signaling acknowledgment messages (ACK's) for one or more transport channels correctly decoded to terminate the transmission of those transport channels. The techniques may be applied to the transmission of voice signals using the adaptive multi-rate (AMR) codec. Further exemplary embodiments describe aspects to reduce the transmission power and rate of power control commands sent over the air, as well as aspects for applying tail-biting convolutional codes in the system.
