摘要： Apparatus and methods for determining a location estimate of a mobile device based on an extended set of assistance data are presented. The extended assistance data includes assistance data for base stations, such as cellular base stations and access points, not expected to be viewable by the mobile device in a (current) first geographical area but expected to be viewable by the mobile device in a (future) second geographical area. By seeding the mobile device with assistance data expected to be useful in the future, the network reduces messaging between the network and mobile device and battery consumption by the mobile device.

摘要： Techniques for sending resource requests in a wireless communication system are described. Multiple types of quality of service (QoS) information may be supported for resource requests and may include QoS class and latency deadline. A terminal may have data to send on the reverse link and may determine QoS information for the data. The QoS information may include at least one QoS type, which may be dependent on a configuration selected for use to send resource requests. The terminal may also determine backlog level information indicative of the amount of data to send. The terminal may generate a resource request with the backlog level and QoS information. The resource request may include the backlog level information and QoS class information, the backlog level information and either QoS class information or latency deadline information, the backlog level information and latency deadline information, or some other combination of information.

摘要： 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.

摘要： Techniques for transmitting pilot and traffic data are described. In one aspect, a terminal may scramble its pilot with a scrambling sequence generated based on a set of static and dynamic parameters. The static parameter(s) have fixed value for an entire communication session for the terminal. The dynamic parameter(s) have variable value during the communication session. The terminal may generate a scrambling sequence by hashing the set of parameters to obtain a seed and initializing a PN generator with the seed. The terminal may then generate the pilot based on the scrambling sequence. In another aspect, the terminal may use different scrambling sequences for pilot and traffic data. A first scrambling sequence may be generated based on a first set of parameters and used to generate the pilot. A second scrambling sequence may be generated based on a second set of parameters and used to scramble traffic data.

摘要： A quick paging channel in a random access wireless communication system includes at least one bit in a quick paging frame identifying the presence of a paging message for an access terminal or group of access terminals. The quick paging bits identifying the presence of a paging message for a first access terminal is encoded with one or more quick paging bits corresponding to one or more additional access terminals to produce one or more forward error correction bits. The jointly encoded quick paging bits are broadcast to the access terminals by time division multiplexing the quick paging frame with additional frames of information.

摘要： Systems and methodologies are described that facilitate enhancing acquisition and handoff in a wireless network deployment by leveraging primary pilots and secondary pilots. The deployment can support more than one frequency band for operation, yet a mobile device can receive signals on one frequency band at a given time. Thus, a base station can transmit primary pilot(s) over frequency band(s) associated with operating data channel(s) as well as secondary pilot(s) over frequency band(s) that lack data channel(s) for the base station. Moreover, the base station can convey information that indicates to a mobile device whether each pilot is primary or secondary. Further, the mobile device can employ knowledge of pilot type (e.g., primary or secondary) as well as signal strength to effectuate handoff decisions; thus, disruptions in communication can be mitigated.

摘要： To improve performance in devices capable of communication using multiple radio access technologies (RATs), a gap pattern may be constructed in which a first RAT is quieted during certain times to allow for a second RAT to operate without interference. Gap patterns may be constructed based on timeline constraints, such as grant scheduling and HARQ performance, or based on desired performance levels of one or more of the RATs. Gap patterns may be selected by a user equipment or base station. Gap patterns may be selected to protect information in certain subframes. Potential gap patterns may be assigned weights indicating their desirability.

摘要： A reference signal management (RSM) program executing on a mobile device detects multiple reference signals, allocates those reference signals into groups, and performs reference signal management functions using information conveyed in the reference signals. The RSM program detects both broadband and narrowband reference signals and maintains updated groups of reference signals that are transmitted from access points with independent configurations or different radio technologies. Battery power of the mobile device is efficiently used to manage reference signals in heterogeneous network environments by preventing unnecessary handoffs, overhead downloads, access probes and new registrations. Reference signals are managed from both synchronous and asynchronous sectors and in idle mode as well as in connected state mode. The RSM program performs functions such as managing handoffs between access points, managing an idle mode of the mobile device, managing an active group of the detected reference signals, and collecting overhead parameters for the mobile device.
