Abstract: Wireless communications systems and methods related to user equipment (UE) idle mode mobility in a wireless communication network are provided. A wireless communication device establishes a network session with a wireless communication network. The wireless communication device reselects a first cell for camping, wherein the first cell is associated with the wireless communication network. The wireless communication device monitors for first system information from the first cell. The wireless communication device reselects a second cell for camping in response to a failure to receive the first system information. The second cell is associated with the wireless communication network and different from the first cell. The wireless communication device maintains the network session during the reselecting the first cell for camping and the reselecting the second cell for camping.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus selects an LTE serving cell and a non-LTE serving cell. Measurement objects corresponding thereto are identified based on a review of broadcasted system information and historical information relating to prior serving cells. The apparatus identifies measurement objects from other radio access technologies (RATs) (WCDMA, CDMA, GSM). The remaining measurement objects may be identified based on measurement identifiers. The apparatus performs wireless measurements based on the selected serving cells and identified measurement objects. The resulting measurements are transmitted to the network for use in determining channel conditions.

Abstract: Traditional rules that apply to cell selection are overridden to allow cell selection on an acceptable cell, in addition to cell selection on a suitable cell. Once a mobile device acquires service on an acceptable cell, mobile device can inform network of the emergency call in progress or initiation of an emergency call, which allows network to perform necessary actions to support the emergency call during establishment/reestablishment.

Abstract: Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.

Abstract: In device-to-device (D2D) communication in a licensed spectrum, selection of a transmit pool and distribution of codes to be transmitted to the transmit pools for more efficient transmission is desired, for a given period. The apparatus may a user equipment (UE) for D2D communication in a licensed spectrum. The UE sets a discovery epoch to a shortest discovery period among discovery periods of a plurality of transmit resource pools, each transmit resource pool of the plurality of transmit resource pools associated with a respective frequency. The UE estimates a channel utilization of each transmit resource pool of the plurality of transmit resource pools based on one or more previous transmissions on each transmit resource pool of the plurality of transmit resource pools. The UE selects a transmit resource pool among the plurality of transmit resource pools for a D2D transmission within the discovery epoch based on the estimated channel utilizations.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine that a number of access stratum (AS) operations or communications have failed while attempting to communicate with a cell. Based on the AS failures, the UE may deprioritize the cell. For example, based on the deprioritization, the UE may bar certain cells from selection or reselection procedures. The UE may thus attempt to select or reselect a different cell even if the cell is ranked lower based on a selection criteria or reselection criteria. In some cases, UEs may store and share historical AS failure information that may also be used to determine when to deprioritize a cell. In some cases, a group of cells may be deprioritized (e.g., a group based on frequency, network, or tracking area).

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus performs a handover from a source cell to a target cell. The apparatus determines a decoding timer value based on network conditions. The apparatus attempts to decode a MIB or a SIB from the target cell within a time after the handover corresponding to the decoding timer value. The apparatus triggers a radio link failure (RLF) when the MIB or the SIB is not decoded within the time corresponding to the decoding timer value.

Abstract: A method for inter-frequency cell reselection by a wireless communication device is described. The wireless communication device camps on a serving cell. An evolved multimedia broadcast multicast service (eMBMS) service provided by a neighbor cell is discovered. Inter-frequency parameters of the neighbor cell are measured. It is determined whether to perform an inter-frequency cell reselection based on one or more inter-frequency cell reselection factors. An inter-frequency cell reselection to the neighbor cell is performed.

Abstract: Systems and methodologies are described herein that facilitate cell barring based on erroneous messages received within a wireless communication system. As described herein, in the event that a device fails to receive and/or decode respective messages transmitted from a network cell over a common communication channel, the device can implement one or more error handling procedures as described herein to reselect away from the network cell and/or a frequency associated with the network cell (e.g., as if the network cell was explicitly barred). Cell barring can be triggered as described herein based on a count of erroneous messages (e.g., consecutive messages, messages received within a predetermined time window, etc.), elapsed time between erroneous messages, or the like. Further, cell barring can be performed as described herein based on failure to acquire pre-scheduled system information, common system information determined to have invalid abstract syntax, or the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a parameter associated with a secondary cell group. The UE may perform an optimization response action for a dual connectivity mode of a first frequency parameter or a second frequency parameter when the parameter satisfies a threshold, wherein the optimization response action is associated with whether the secondary cell group is operating with the first frequency parameter or the second frequency parameter. Numerous other aspects are described.
