Methods, systems, and devices for wireless communication are provided for mobility management for wireless communications systems that utilize a flexible bandwidth carrier. Some embodiments include approaches for determining bandwidth information, such as one or more bandwidth scaling factors N and/or flexible bandwidths, at a user equipment (UE), where the bandwidth information may not be signaled to the UE. Embodiments for determining bandwidth information include: random ordered bandwidth scaling factor approaches, delay ordered bandwidth scaling factor approaches, storing bandwidth scaling factor value in UE Neighbor Record approaches, spectrum measurement approaches, spectrum calculation approaches, and/or a priori approaches. Flexible bandwidth carrier systems may utilize spectrum portions that may not be big enough to fit a normal waveform. Flexible bandwidth carrier systems may be generated through dilating, or scaling down, time, frame lengths, bandwidth, or the chip rate of the flexible bandwidth carrier systems with respect to a normal bandwidth carrier system.

Bandwidth information determination for flexible bandwidth carriers

A user equipment (UE) may receive a wireless wide area network (WWAN) signal on a first antenna. The UE may process the WWAN signal with a portion of a WWAN receive chain of a WWAN module of the UE. The WWAN signal may be routed from the WWAN receive chain to a wireless local area network (WLAN) receive chain of a WLAN module of the UE. The UE may then process the WWAN signal with a portion of the WLAN receive chain.

A method of wireless communication includes communicating using a first radio based on a first radio technology; configuring a second radio based on a second radio technology different from the first radio technology to assist the first radio with a first-radio operation; and performing at least a portion of the first-radio operation at the second radio. The first-radio operation includes at least one of multiple subscriber identity module (SIM) page monitoring and page/data processing, higher order diversity data acquisition and processing, interference measurement and management, E-UTRAN cell global identifier (ECGI) determination and reporting, a reference signal time difference (RSTD) measurement, beacon detection for small cell identification, a minimization of drive test (MDT) measurement, and a speed estimation measurement.

An example method may include receiving, by a computing device, control plane signaling associated with a first service to be performed by a first communication device, wherein the computing device is within a radio access network (RAN) and is in limited communication with a core network via a backhaul connection that is constrained due to a backhaul bottleneck condition. The example method may include conditionally permitting, by the computing device, a first feature of the first service based at least in part on the backhaul bottleneck condition. Another example method may include receiving, by a computing device, control plane signaling associated with a service to be performed by a first communication device, wherein the computing device is within a RAN and is in limited communication with a core network via a backhaul connection that is constrained due to a backhaul bottleneck condition.

A user equipment (UE) may communicate over a first wireless wide area network (WWAN). The first WWAN may be supported by a first subscriber identity module (SIM) of the UE. The UE may also communicate simultaneously over a second WWAN supported by a second SIM. The UE may process the second WWAN communication with a portion of a WWAN module and a portion of a wireless local area network (WLAN) module.

Methods, systems, and devices are disclosed for providing services, such as voice services, within flexible bandwidth systems. In general, the scaling of one or more aspects of a flexible bandwidth system may be compensated for through altering one or more aspects within a code domain. The tools and techniques may include scaling spreading factors (with rate matching tuning in some embodiments), multi-code transmission, code rate increases, AMR codec rate adjustments, and/or higher order modulation. Subframe decoding approaches for the reception scheme may also be utilized. These tools and techniques can be flexibly implemented on the mobile device and/or base station side. Some embodiments may also minimize the latency introduced by the transmission and/or reception process. Flexible bandwidths systems may utilize portions of spectrum that may be too big or too small to fit a normal bandwidth waveform.

Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.

Techniques are provided to facilitate offloading of mobile entities from a serving network entity. For example, there is provided a location-based method that involves, in response to a load of the requesting entity exceeding a load threshold, identifying candidate network entities to which to offload a user equipment (UE), each of the candidate network entities being in sleep mode. The method may involve determining coverage and location information for the candidate network entities, and determining location information for the UE. The method may involve selecting a given network entity to turn ON based at least in part on the coverage information and the location information. The method may involve sending an ON-request message to the at least one selected network entity, the ON-request message including a timer that can be used to deactivate the selected network entity in case it is not useful in offloading the serving network entity.

A mobile device may perform an out-of-band (OOB) search for the femtocell, the OOB search triggered by a proximity detection configuration command from the macrocell. The mobile device may wirelessly communicate with a located femtocell via an OOB link, and receive femtocell information from the femtocell via the OOB link. The mobile device may transmit the received femtocell information to the macrocell. The macrocell may generate instruction for a mobile device search based on the femtocell information. The macrocell may transmit such instructions to the mobile device for an in-band search for the femtocell.

A method and system provide assisted acquisition of a wireless link between user equipment and a femtocell unit. After an initial calibration of timing and/or frequency information, the user equipment enters into a low-power state. The femtocell unit monitors for system updates using a network listen module that sniffs the air interface of one or more neighboring cells. Upon a trigger event, the femtocell unit provides aiding information, for example, timing and/or frequency information corresponding to a change in timing and/or frequency of the air interface, over a second radio, e.g., a wireless personal area network interface. Thus, the user equipment may remain in the low-power state and receive updates with respect to the wireless wide area network interface. Subsequently, upon wake-up, the user equipment may utilize the aiding information, for example, to recalibrate its timing and/or frequency. Thus, acquisition of the wireless link with the femtocell unit may be expedited.
