Abstract:
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.
Abstract:
Methods and apparatus for power management comprise detecting, at a user equipment (UE), a state transition trigger, wherein the state transition trigger indicates a current data transmission termination or an anticipated data transmission termination. Further, the methods and apparatus comprise sending a state transition indication to the network entity in response to detecting the state transition trigger. Moreover, the methods and apparatus comprise adjusting a state of the UE based at least in part on sending the state transition indication to the network entity.
Abstract:
Methods and apparatus for wireless communication in a mobile device that includes transmitting a radio resource control (RRC) request message, wherein the RRC request message includes a non-access stratum (NAS) service request. Aspects of the methods and apparatus include receiving an RRC connection setup message comprising information for configuring an RRC connection. Aspects of the methods and apparatus also include transmitting an RRC connection setup completion message acknowledging the instructions for configuring the RRC connection.
Abstract:
User Equipments (UEs) can be adapted to enter into a lower RRC state from a higher RRC state, and search for one or more layers of higher priority within a predetermined period of time upon entering into the lower RRC state. According to at least one aspect, this search for one or more layers of higher priority may be performed irrespective of RF quality of a current serving cell. According to at least another aspect, this search for one or more layers of higher priority may be conducted within the predetermined period of time if a wait period has elapsed since the UE camped on the current serving cell. If the wait period has not elapsed since camping on the current serving cell, the search for one or more layers of higher priority may be performed within the predetermined period of time following a duration of the wait period.
Abstract:
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.
Abstract:
Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.
Abstract:
Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.
