Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.

Enhanced power savings through mobile initiated dormancy

Methods, systems, and devices for wireless communications are described that provide for call continuity following radio link failure (RLF) through re-establishment of a voice call using a same or different radio access technology (RAT) before the call is dropped. Upon detection of RLF on a connection supporting a voice call, a UE may initiate a drop call timer and scan for available connections. The voice call may be attempted to be re-established if a connection is available on using a RAT of an existing connection. The voice call in such cases may continue without the call being dropped. Upon expiration of the drop call timer, the UE may attempt to establish a connection using a RAT identified during the duration of the drop call timer.

Voice call management techniques in wireless communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine location information regarding the UE; and activate a receive beam of the UE in at least one symbol, associated with at least one transmit beam of at least one base station, based at least in part on the location information, wherein the UE is configured to activate the receive beam based at least in part on mapping information, at least partially determined by the UE, that indicates that the receive beam is associated with the location information. Numerous other aspects are provided.

Techniques and apparatuses for measuring beam reference signals based at least in part on location information

The disclosure provides for a UE handling messages in wireless communication. The disclosure provides for a UE partially exchanging a first signaling-related message associated with a first UE configuration with a network entity and triggering a state transition message that initiates a change to a second UE configuration different from the first UE configuration. In an aspect, the UE determines that the first message has not been successfully received or successfully transmitted. In an aspect, the UE sends an indication message to coordinate discarding of the first message with the network entity and receives, after sending the indication message, a second signaling-related message associated with the second UE configuration. In another aspect, the UE, after partially sending a signaling-related message, receives a reconfiguration request associated with a second UE configuration. In an aspect, the UE determines that the message has not been successfully transmitted and causes a reconfiguration failure.

UE handling of stale or incomplete PDUs after cell reselection or reconfiguration

The present aspects relate to enabling a user equipment (UE) to operate in Dual Carrier mode during wireless communication, including generating an event trigger to be transmitted to a network entity in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network. The aspects further include determining whether a plurality of optimization conditions are met, and modifying a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity and resets the trigger timer.

Event 6D enhancements

Aspects related to allocating transmission power in wireless communications are described. It can be determined whether data is to be transmitted on an uplink control channel in one or more upcoming transmission time intervals (TTIs). Based on this determination, transmission power is allocated to an uplink enhanced dedicated channel in the one or more upcoming TTIs. Where uplink control channel data is not to be transmitted in the one or more upcoming TTIs, transmission power that would have been used for the uplink control channels can instead be allocated to the enhanced dedicated channel.

Techniques for optimizing transmission power allocation in wireless communications

Aspects described herein relate to transmitting hybrid automatic repeat/request (HARQ) data in continuous packet connectivity (CPC) mode. Data is transmitted to a network according to a discontinuous transmit (DTX) cycle in a CPC mode. The CPC mode can be exited, however, based at least in part on detecting available HARQ data for transmission. In this regard, a next transmission opportunity configured for transmitting the available HARQ data is determined, where the next transmission opportunity is not within a transmission time instance defined by the DTX cycle, and the available HARQ data is transmitted during the next transmission opportunity outside of the CPC mode.

Transmitting data outside of a discontinuous transmit (DTX) cycle in wireless communications

Aspects of the present disclosure provide for a method and an apparatus for wireless communications using an intelligent Random Access Channel (RACH) procedure that may increase the probability of obtaining an available E-DCH resource quickly in a Universal Mobile Telecommunication System.

Method and apparatus for a smart random access procedure in a telecommunication network

Described herein are various aspects related to determining whether to read system information of a network entity. A user equipment (UE) can receive system information transmitted by a network entity. The UE can analyze one or more parameters of the system information to determine whether system information for the network entity has changed when a value tag broadcasted in the system information is equivalent to a stored value tag for the network entity; thus the UE can utilize more than just the value tag, such as system information size, system information scheduling, a value tag in master information, and/or the like, at least in instance where the value tag may be the same in different transmissions of the system information. The UE can process the system information for the network entity based at least in part on determining that the system information for the network entity has changed.

Techniques for reading system information in wireless communications

Aspects of user equipment capability reporting include receiving a paging signal for a second subscription during a tune away from an active voice call on a first subscription, sending a report of less than a full set of user equipment capability information to the network for the second subscription during a connection setup in response to the paging signal for the second subscription, extracting a caller identification (ID) associated with the paging signal for the second subscription during the tune away from the voice call on the first subscription, and initiating a transmission to the network for sending the full set of UE capability information for the second subscription in response to the voice call on the first subscription ending.

User equipment capability report management during caller ID extraction

Data is selectively transmitted over one or more carriers of a set of carriers. According to some aspects of the disclosure, a decision may be made to forgo the transmission of a preamble via one of the carriers (e.g., channels). For example, in a multi-carrier system, transmission of a preamble via one carrier may be inhibited if all of the data can be transmitted via another carrier. According to some aspects of the disclosure, a decision may be made to transmit different types of data on a single carrier rather than on multiple carriers. For example, a single carrier may be used to transmit schedule data and non-scheduled data if all of the data can be transmitted on one of the carriers (e.g., during a single transmission time interval). In this case, transmission of a preamble on another one of the carriers may therefore be inhibited.

Enhancements for transmission over multiple carriers

Methods and apparatus are described for improving call performance and data throughput. The methods and apparatus include receiving one or more packet data units (PDUs) during a transmission time interval (TTI) from a network entity, wherein the one or more PDUs are associated with a radio bearer. Further, the methods and apparatus include determining one or more out-of-order PDUs from the one or more PDUs. Moreover, the methods and apparatus include reordering the one or more out-of-order PDUs, wherein the one or more out-of-order PDUs are reordered within the TTI. Additionally, the methods and apparatus include processing the one or more reordered PDUs.

Methods and apparatus for improving call performance and data throughput

An example method may include receiving a first subframe. In addition, the example method may include decoding information transmitted in the first subframe. Further, the example method may include switching to an inactive mode subsequent to the completion of the reception of the first subframe. Further still, the example method may include exiting the inactive mode and decoding downlink data transmitted in one or more second subframes in a current reception (Rx) burst time interval when the decoded information transmitted in the first subframe indicates an upcoming transmission of downlink data in the one or more second subframes.

Discontinuous reception management

Access terminals are adapted to facilitate optimized tune-away operations in multi-subscription wireless communication devices. According to one example, an access terminal can communicate on a first subscription. After a period of time, the access terminal can tune away from the first subscription to a second subscription to perform a communication activity corresponding to the second subscription. After tuning back to the first subscription, the access terminal may transmit uplink data while ignoring any absolute grant received after tuning back to the first subscription, and/or transmit a scheduling information message in response to tuning back to the first subscription from the second subscription. Other aspects, embodiments, and features are also included.
