Abstract: Methods, systems, and devices for wireless communications are described that provide for channel-bandwidth-attributed per-band user equipment capability reporting. A user equipment (UE) may determine a first and second set of physical layer capabilities associated with a first and second channel bandwidth, respectively. The UE may transmit a first and second UE capability report to the base station, where the capability reports may indicate the corresponding channel bandwidth and may include the UE physical layer capabilities. The UE may receive control information indicating a channel bandwidth from the base station and the UE may communicate with the base station according to the received control information.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a base station (BS). The method generally includes receiving an indication of current remaining available transmit power from a user equipment (UE). The method further includes communicating information indicating a data rate parameter and a communication configuration to the UE. The data rate parameter is for use by the UE on an uplink with the BS. The communication configuration affects uplink transmission duty cycle on the uplink based on whether the current remaining available transmit power and a current channel state between the BS and the UE satisfy a condition. The method further includes receiving signals based on the data rate parameter and the communication configuration from the UE on the uplink.

Abstract: A user equipment (UE) expedites cell reselection by reselecting a neighbor cell prior to call setup. In one instance, the UE measures a signal quality of a serving cell and a signal quality of the neighbor cell. The UE starts a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell. The UE reselects the neighbor cell prior to a scheduled expiration of the reselection timer.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to employ a discretionary on mode (e.g., powering receiver circuitry) in order to conserve power during discontinuous reception. The UE may discretionarily cut down an on time duration by delaying wake-up (e.g., powering on receiver circuitry) or by sleeping (e.g., powering down receiver circuitry) during portions of an on duration. The UE may also discretionarily skip one or more on durations. The UE may use hybrid automatic repeat request retransmissions to receive information that may be missed when sleeping during a configured on duration. The UE may evaluate one or more conditions in order to determine whether to employ a discretionary on mode. For example, the UE may determine to conserve power based on one or more of a data traffic type, a battery level, a channel condition, a retransmission policy, or physical layer activities.

Abstract: Long term evolution (LTE) common reference signal (CRS)-assisted new radio (NR) tracking operations are disclosed. A user equipment (UE) may obtain a colocation indication identifying a quasi-colocation (QCL) status of a legacy network downlink antenna associated with one or more cell-specific reference signal (CRS) resource elements (REs) and an advanced network downlink antenna in communication with the UE. The UE may then perform a tracking loop operation for the advanced network using the one or more CRS REs of the legacy network in response to the QCL status indicating a QCL state, wherein the QCL state indicates the legacy network downlink antenna is quasi-colocated with the advanced network downlink antenna.

Abstract: A user equipment (UE) expedites cell reselection. In one instance, the UE starts a reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.

Abstract: Embodiments described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, using a reduced re-order release timer having a reduced length in response to determining that a length of a tune-away interval exceeds a threshold. In some embodiments, a reduced status prohibit timer is initiated in response to determining that the length of the tune-away interval exceeds a threshold. In some embodiments, two or more status reports are transmitted during a same status prohibit timer in response to determining that transmission window occupancy exceeds a threshold.

Abstract: Various embodiments may include methods for handling collisions between a first subscription and a second subscription of a wireless communication device. In various embodiments, a processor of the wireless communication device may determine whether there are persistent collisions between periodic paging wake-ups on the first subscription and periodic inter-RAT measurements on the second subscription. When persistent collisions are detected, the time for performing each inter-RAT measurement on the second subscription may be extended sufficient to enable completing inter-RAT measurements on the second subscription. The amount by which the time for performing inter-RAT measurements is extended may depend upon the timing and duration of the persistent collisions.

Abstract: A method and apparatus for reducing call drop rate by validating reconfiguration messages based on service data unit (SDU) lifetime are described. A receiving device, such as a user equipment, may determine a receiving delay between receiving a first protocol data unit (PDU) and receiving a last PDU of a reconfiguration message SDU. The receiving delay may be compared with an SDU lifetime. The reconfiguration message SDU may be validated based on the comparison of the receiving delay with the SDU lifetime. A receiving delay that is greater than the SDU lifetime may indicate that the SDU is stale and, therefore, invalid. A receiving delay that is less than the SDU lifetime may indicate that the timing of the SDU is valid and the reconfiguration message SDU is to be processed. An activation time of the reconfiguration message SDU may also be honored or disregarded based on the receiving delay.

Abstract: When a user equipment (UE) is communicating wirelessly over a wireless communication network and terminates wireless communication temporarily due to power limit constraints (such as to satisfy a specific absorption rate (SAR) threshold), the UE may maintain its radio access network (RAN) identification (ID) and domain context, in order to quickly resume wireless communication, and avoid upper layer connection setup, once the UE is no longer power limited.

Abstract: Systems and methodologies are described that facilitate random access procedures using one or more fallback access schemes after initial access attempts have failed. UE equipped to determine failure of a first access request to a first base station due to interference from a second base station. Further, a UE equipped to determine the failure can do so and implement one or more fallback access schemes in response to the determination. In one example, a fallback access scheme allows the UE to select a secondary carrier frequency for communications with the first base station. In another example, a fallback access scheme allows the UE to designate the first base station as inaccessible and communicate with other base stations.

Abstract: A method and apparatus for avoiding call drops during Serving Radio Network Subsystem (SRNS) relocation procedure are described. In an aspect, the method may include receiving an SRNS RELOCATION message and initiating a handover procedure from a first radio network subsystem (RNS) to a second RNS based on the SRNS RELOCATION message. The method may include identifying a downlink (DL) message and identifying an uplink (UL) message. The method may include holding the DL message and the UL message at a radio resource control (RRC) layer until completion of the handover procedure. In another aspect, the SRNS RELOCATION message may include a new FRESH value. The method may include retaining an old FRESH value determined before the SRNS RELOCATION was received. The method may include applying both the old FRESH value and new FRESH value to the DL message to determine if the DL message is valid.

Abstract: Methods and apparatus for wireless communication for improving handover between a network and a user equipment (UE) when a measurement report is received. Aspects of the methods and apparatus relate to determining the quality of a serving cell associated with a fast handover performance threshold. When the fast handover performance threshold is breached, the UE may transmit a measurement report requesting a handover to a target cell. Upon requesting a handover to a target cell when the fast handover performance threshold is breached, the UE receives a handover trigger allowing handover to a target cell.

Abstract: Methods for improving the time to acquire an identity of a base station by a mobile station, by relying on locally-unique attributes of the base stations instead of globally-unique attributes of the base stations, are presented. In some embodiments, data may be requested, the data may contain a globally unique attribute of a base station, a first locally unique attribute of the base station, and a second locally unique attribute of the base station. In some embodiments, data may be received in response to the request, the data may contain at least the first locally unique attribute and the second locally unique attribute. It may then be determined that the data did not contain the globally unique attribute, and an identity of the base station based at least in part on the first locally unique attribute and the second locally unique attribute may be acquired.
