    Abstract: Systems and methods for managing communication in an unlicensed band of frequencies to supplement communication in a licensed band of frequencies in unlicensed spectrum are disclosed. The management may comprise, for example, monitoring utilization of resources currently available to a first Radio Access Technology (RAT) via at least one of a Primary Cell (PCell) operating in the licensed band, a set of one or more Secondary Cells (SCells) operating in the unlicensed band, or a combination thereof. Based on the utilization, a first SCell among the set of SCells may be configured or de-configured with respect to operation in the unlicensed band.

    Abstract: The present aspects relate to methods and apparatuses to power off a modem receiver or components of the receiver at a time prior to the end of the frame based on data in the frame being received and properly decoded before the end of the frame. In an aspect, the apparatuses and methods provide power saving in a wireless device, and include receiving data within a frame at a user equipment, determining whether all payload packet data has been correctly decoded prior to an end of the frame, and powering down a receiver component for a portion of a remainder of the frame in response to determining that all payload packet data has been correctly decoded and where a first time period to a next scheduled overhead bit transmission period of a slot in the frame is greater than a second time period corresponding to a warm-up period for the receiver component.

    Abstract: A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The A may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.

    Abstract: An access terminal (AT) and a data-optimized cellular communication radio network (RN) negotiate a set of packet sizes for use on a reverse link between the AT and the RN. The negotiated set of packet sizes may differ from the default set of packet sizes defined in an existing standard, such as 1xEV-DO Revisions A and B. The packet sizes in the negotiated set may be tailored to provide a good fit with an application transmitting data on the reverse link, such as a voice encoder of a voice over Internet Protocol (VoIP) application. The AT and the RN communicate using the negotiated set of packet sizes. The packet sizes of the negotiated set may be mapped to the same reverse rate indicator (RRI) channel codewords as are defined in systems operating under the standard. Packing efficiency is thus increased, and higher capacity for delay-sensitive applications is achieved.
