Abstract: The present aspects relate to out-of-service searches in a wireless communication system. Specifically, the present aspects provide that while in an out-of-service state corresponding to a radio resource disconnection, a user equipment (UE) may determine that a first time duration following entry into the out-of-service state has elapsed. The UE may further obtain a geofence identifier representing a shape forming a geographic region including one or more boundaries based on determining that the first time duration has elapsed. The UE may further identify at least one location identifier based at least on the geofence identifier and determine at least one radio access technology (RAT) and one or more associated frequency bands based on the at least one location identifier. The UE may further search on the at least one RAT and one or more associated frequency bands for at least one network entity within the geographic region.

Abstract: Aspects of the present disclosure provide methods and apparatuses that use various connection reconfiguration signaling schemes to enable fast user equipment reconfiguration in wireless networks. A network can reduce reconfiguration signaling traffic or overhead by reducing the amount of configuration data sent to each user equipment (UE) in a reconfiguration message. In some examples, when a UE first enters a network area, the network may provide the UE with a list of commonly used baseline configurations. Each baseline configuration may be identified by an index and a value tag. Subsequently, the network may transmit a reconfiguration message including, for example, only the index and value tag to indicate the desired configuration.

Abstract: A user equipment (UE) can establish a first connection using a first radio access technology (RAT), wherein the UE operates in a communication mode having one or more dormant periods with respect to the first connection. The UE can receive a data packet over a second connection using a second RAT, wherein the data packet is from a data flow which is allowed or configured to be delivered via the first connection and the second connection. It can be determined that the data packet is received over the second connection when the UE is operating in a dormant period of the one or more dormant periods with respect to the first connection. A termination of the dormant period over the first connection can be requested based at least in part on determining that the data packet is received when the UE is operating in the dormant period.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may establish radio bearers for certain data transmissions between a user equipment (UE) and a base station. A radio bearer may be associated with one or more quality of services (QoS) parameters, such as a bit rate. The base station may indicate to the UE a time window over which to average the bit rate. In some examples, a radio bearer may include multiple data flows. The base station may provide information regarding QoS parameters for each data flow in control signaling, such as a grant.

Abstract: A first method includes transmitting, to a network, an indication of a capability to operate in an uplink aggregation dual connectivity mode or in a fast switching dual connectivity mode; and receiving, from the network, a dual connectivity configuration for the UE based at least in part on the indication of the capability. A second method includes communicating with a first network access device; transmitting, to a second network access device, a request to perform fast switching from the first network access device to the second network access device; receiving, from the second network access device, a dual connectivity configuration for communicating with the second network access device; and communicating with the second network access device based at least in part on the dual connectivity configuration.

Abstract: A person may utilize multiple connected devices, such as smart watches, user equipments (UEs), smartphones, tablet computers, and/or the like, which may each be assigned unique phone numbers. Operators may assign a common phone number to the multiple connected devices; however, the phone number is not used in the access stratum path of a radio access technology resulting in multiple paging procedures being performed for the multiple connected devices. In implementations, described herein, a first UE, such as a smartphone, may obtain paging information associated with decoding paging messages for a second UE, such as a smart watch. The first UE may use the paging information to decode a paging message of a combined paging cycle established for the first UE and the second UE, thereby obviating a need for multiple paging cycles for the first UE and the second UE.

Abstract: Techniques are described for wireless communication. A base station may indicate to a UE, in a pre-wakeup period, whether the base station will transmit a grant to the UE. The pre-wakeup period may occur at the beginning of a DRX cycle. The base station may transmit an indication of a grant to the UE, and the base station may indicate a time period during which the UE may wake up to receive the grant. The indication may include scheduling information for the grant. The UE may select a DRX mode based on a configuration received from the base station, a traffic pattern, or scheduling history. The UE may monitor for the grant, and receive the grant. In other examples, the UE or the base station may identify that the grant was not received, and may reset a DRX cycle based on the identification.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to power savings based on distributed enhanced machine type communication (eMTC) functions, for example, between an applications processor and a modem of an eMTC device. An example method generally includes entering a power saving mode (PSM), wherein entering the PSM includes performing a first power collapse of an applications processor of the wireless node and a modem of the wireless node into a low power state; exiting the PSM at expiry of a wake-up timer, wherein exiting the PSM includes waking up the applications processor and the modem from the low power state to an active power state; and in response to exiting the PSM, performing a second power collapse of the applications processor into the low power state while the modem operates in the active power state.

Abstract: LUE capability information is provided for coordination across multiple RATs or for single-RAT connectivity where UE capabilities may change or be reported according to capability groups. A base station may establish a first connection with a UE using a first RAT, and determine that the first connection is to be reconfigured, such as due to data transmission requirements exceeding the capacity of the currently configured connection. The base station may receive UE capability information, such as in response to a capability query transmitted to the UE. The base station may reconfigure the connection with the UE based on the UE capability response through initiating a second connection with a second base station using a second RAT, through reconfiguring the first connection, or combinations thereof.
