20080311900 | CELL SELECTION - To determine a cell for usage in wireless communication, a signal-to-noise ratio or a signal-to-power ratio can be used in selecting an appropriate cell. However, cell selection can also configure to take both signal-to-noise ratio and signal-to-power ratio into account. Multiple available cells can be analyzed and a highest ranking cell can be selected through balancing the aforementioned ratios. In addition, to minimize transferring between cells, a limitation can be placed such that a cell is not left unless there is better of both the aforementioned ratios at another cell. | 12-18-2008 |
20110111765 | SYSTEM AND METHODS FOR TRAFFIC VOLUME REPORTING DURING RADIO ACCESS NETWORK CONNECTION SETUP - Disclosed are systems, methods and computer program products for traffic volume reporting during radio access network (RAN) connection setup. In one aspect, the RAN broadcasts an indicator that it accepts traffic volume measurements (TVM) from access terminals (ATs) and an associated TVM threshold. An AT measures its traffic volume before requesting a connection with the RAN. If the traffic volume is above the threshold, AT transmits to the RAN a connection request containing a TVM indicator that the measured traffic volume from the AT is above the threshold. If the traffic volume is below the threshold, AT transmits to the RAN a connection request containing a TVM indicator that the traffic volume is below the threshold. | 05-12-2011 |
20120213058 | APPARATUS AND METHOD FOR FACILITATING FALLBACK ACCESS SCHEMES - Systems and methodologies are described that facilitate random access procedures using one or more fallback access schemes after initial access attempts have failed. UE equipped to determine failure of a first access request to a first base station due to interference from a second base station. Further, a UE equipped to determine the failure can do so and implement one or more fallback access schemes in response to the determination. In one example, a fallback access scheme allows the UE to select a secondary carrier frequency for communications with the first base station. In another example, a fallback access scheme allows the UE to designate the first base station as inaccessible and communicate with other base stations. | 08-23-2012 |
20120264416 | SELECTIVE STATE TRANSITIONS OF A USER EQUIPMENT WITHIN A WIRELESS COMMUNICATIONS SYSTEM - In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications. | 10-18-2012 |
20130072123 | CHANNEL QUALITY REPORTING USING A DYNAMICALLY ADJUSTED MEASUREMENT POWER OFFSET - Methods and apparatuses are provided for facilitating dynamic measurement power offset adjustments for use in reporting channel quality feedback. A user equipment may generate and send a plurality of channel quality indicator (CQI) values to a base station. The base station determines whether at least some of the received CQI values are outside of an upper or lower threshold value. If at least some of the received CQI values are outside the upper or lower threshold value, the base station can transmit an adjusted measurement power offset to the user equipment. On receipt of the adjusted measurement power offset, the user equipment generates subsequent CQI values using the adjusted measurement power offset. | 03-21-2013 |
20140153500 | METHODS, SYSTEMS, AND DEVICES FOR CONFIGURING MAXIMUM TRANSMIT POWER - Methods, systems, and devices are disclosed for configuring maximum allowed transmit power for wireless communications systems. Some embodiments treat multiple traffic types, such as voice traffic and data traffic, separately with respect to one or more maximum allowed transmit power limits. In some cases, at least first transmit power limit for at least a first traffic type and/or at least a second transmit power limit for at least a second traffic type may be determined. At least the first transmit power limit with respect to the first traffic type or the second transmit power limit with respect to the second traffic type may be utilized. Some embodiments are configured to utilize flexible bandwidth carriers. | 06-05-2014 |
