For example, a Traffic Priority parameter in a media access control (MAC) message can be used to transmit the priority level for a new BE category service flow. The MAC message can be an AAI DSA-REQ message (specified in IEEE 802.16m draft 9 (2010)). Either a base station or a mobile station can request a new service flow using the MAC message. | 11-03-2011 |
20130114485 | REDUCING WIRELESS POWER CONSUMPTION AND SIGNALING OVERHEAD FOR INTERNET APPLICATION BACKGROUND MESSAGES - Technology is discussed for reducing the frequency of signaling overhead and power consumption on wireless mobile devices employed to support internet applications in a Wireless Wide Area Network (WWAN). Demands for battery power and signaling overhead frequently arise to support background messages of little significance and/or urgency when internet applications are unattended on wireless mobile device attempting to conserve power. An identification module can be triggered to identify such background messages, based on a variety of factors. The identification module can also determine whether to buffer and/or drop such messages with information local to the wireless mobile devices and/or in such background messages. Such buffering and dropping measures can reduce the frequency with which wireless mobile devices consume large amounts of power and/or require signaling overhead to send and receive these background messages. | 05-09-2013 |
20130115990 | SCHEDULING REQUESTS FOR WIRELESS COMMUNICATION DEVICES RUNNING BACKGROUND APPLICATIONS - In embodiments, a user equipment (UE) may transmit, to an evolved Node B (eNB), a background indicator that the UE is in a background mode running one or more background applications and no active applications. The eNB may receive background indicators from a plurality of UEs, and may bundle the background-mode UEs into one scheduling request (SR) allocation block. The individual UEs may be assigned different resource elements within the block on which to transmit an SR indicator (e.g., if the UE has data to send to the eNB). The eNB may lengthen the period between SR allocations for the background-mode UEs compared with active-mode UEs. In some embodiments, the UE may exclusively use the assigned SR allocation instead of a random access channel to notify the eNB that the UE has data to send. | 05-09-2013 |
20130231120 | NETWORK VETTING OF WIRELESS MOBILE DEVICE INITIATED DISCONNECT - Technology is discussed for allowing a wireless mobile device, such as a User Equipment (UE), to coordinate with a Radio Access Network, such as an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN), to tear down a power intensive messaging connection, such as a Radio Resource Control (RRC) connection, to met needs of both the UE and the E-UTRAN. The UE can initiate the tear down process based on information at the UE about the potential need of the UE for the RRC connection and/or the state of the UE's battery charge. The E-UTRAN can then determine whether to grant the request based on the potential overhead involved. The determination can be important to the E-UTRAN because of the large overhead associated with frequent disconnection and re-establishment of the RRC connection. Upon receipt of an affirmative response, the UE can tear down the RRC connection to save battery power. | 09-05-2013 |

The cycle start offset period is selected to provide at least one Hybrid Automatic Repeat Request (HARQ) process reservation pattern to reduce the coexistence interference between the plurality of radio transceivers in the UE. | 11-14-2013 |
20130315094 | RANDOM ACCESS TECHNIQUES FOR FIXED DEVICES IN MOBILE BROADBAND NETWORKS - Briefly, in accordance with one or more embodiments, a fixed device performs a cell search to search for one or more cells on a network and determines a transmit power level to communicate with one of the cells of the network. The fixed device sets a frequency of updating the transmit power level for communication with a cell on the network, wherein the frequency of updating the transmit power level is reduced for the fixed device with respect to a mobile device. | 11-28-2013 |
20140086122 | TECHNIQUES TO CONTROL PAGING FOR FIXED DEVICES - Techniques to control paging for fixed devices are described. An apparatus may comprise a processor circuit, a device identifier component arranged for execution by the processor circuit to determine whether a device is a fixed or mobile device, and a paging component arranged for execution by the processor circuit to generate one or more control directives to modify paging parameters when the device is a fixed device. Other embodiments are described and claimed. | 03-27-2014 |
20140301288 | ENHANCED NODE B AND METHOD FOR RRC CONNECTION ESTABLISHMENT FOR SMALL DATA TRANSFERS - Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) when mobility is to be supported. | 10-09-2014 |
20140362689 | MECHANISM TO ENABLE WIFI OFFLOAD BASED ON POWER PREFERENCE OF USER EQUIPMENT - In typical UEs, scanning for WiFi access points (APs) can consume a significant amount of power. This scanning occurs when the UE is connected through the cellular network, but does not occur when the UE is connected to a WiFi network. As a result, offloading a UE from a cellular network to a WiFi network can allow the UE to conserve power. An issue with existing cellular networks is that the UE cannot inform a cellular network that the UE is running low on power, and therefore cannot direct the cellular network to offload the UE for power conservation reasons. A technique discussed herein allows the UE to indicate its power saving needs to the cellular network. In response, the cellular network can lower (or raise) a particular threshold, so that the UE now exceeds (or no longer exceeds) the threshold, and initiates offloading. | 12-11-2014 |
20140362704 | TRAFFIC SPLITTING BASED ON LATENCY BETWEEN CELLS - Systems and techniques for traffic splitting based on latency between cells are herein described. At an eNodeB, a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) may be measured via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB. The transmission path latency may be compared to a threshold. A layer in a transmission stack to split traffic to the UE may be determined based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB. | 12-11-2014 |
20140362752 | ENHANCED NODE B AND METHODS FOR PROVIDING SYSTEM INFORMATION UPDATES TO USER EQUIPMENT WITH EXTENDED PAGING CYCLES - Embodiments of an enhanced Node B (eNB) and method to provide system information (SI) updates to user equipment (UE) in sleep or idle mode with an extending paging cycle are generally described herein. In some embodiments, a paging message configured to include an optional field to indicate whether there has been a system information (SI) update since a last paging occasion for a UE in sleep or idle mode with an extending paging cycle. System information updates are transmitted by the eNB during a system information modification period that is shorter than a period the extending paging cycle. The optional field may indicate whether or not the UE is to acquire the latest SI update during the current paging occasion. | 12-11-2014 |
