Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may determine a preference of the UE for a termination point between a core network and a radio access network (RAN), the core network and the RAN supporting communications for the UE via at least one or a first cell and a second cell each associated with a multi-connectivity mode of the UE. The UE may transmit, to a base station, an indication of the preference of the UE for the termination point. In some cases, the base station may determine the termination point based on receiving the indication of the preference of the UE, and the base station may transmit a message indicating a configuration for the multi-connectivity mode to the UE, the configuration indicating the determined termination point.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a feedback error configuration indicating an error threshold associated with a feedback error type of a set of feedback error types, and a time window for feedback error detection per frequency band combination. The UE may detect one or multiple feedback errors for the feedback error type within the time window, and determine that a number of the one or multiple feedback errors for the feedback error type exceeds the error threshold. The UE may transmit a feedback error indication based on the determination that the number of the detected one or multiple feedback errors exceeds the error threshold. The feedback error indication may include an indication of the one or multiple feedback errors and the feedback error type associated with the one or multiple feedback errors.

Abstract: A user equipment (UE) receives a circuit switched page from a first radio access technology (RAT) and a command instructing the UE to redirect to a second RAT. The command indicates a designated location area identity of the second RAT. The UE detects base stations of the second RAT and determines whether a strongest base station is in an area identified by the designated location area identity. The UE connects to the strongest base station based on the determining. When the designated location area identity is a permitted location area, the UE connects to the strongest base station when the location of the strongest base station is included in the permitted location area. When the designated location area identity is a prohibited location area, the UE connects to the strongest base station when the location of the strongest base station is not included in the prohibited location area.

Abstract: A user equipment (UE) speed up handover/redirection when the user equipment is in a coverage area of multiple radio access technologies (RATs). In one instance the user equipment determines whether to transmit an uplink (UL) reconfiguration message. The user equipment delays transmission of the uplink reconfiguration message when a transition from a serving radio access technology to a non-serving preferred radio access technology has been initiated while the UE is on a packet switched (PS) data call.

Abstract: A method and apparatus for improved downlink data transport with hybrid automatic repeat request (HARQ) feedback and a measurement gap are provided. A user equipment (UE) receives from a network a transmission grant for downlink data on a first control channel. The UE receives the data from the network via a transport channel. In response to the received data, the UE determines whether transmission of an acknowledgement message falls in a measurement gap. Upon determining that the transmission of the acknowledgement message by the UE falls in the measurement gap, and prior to receiving from the network a retransmission grant for the data on the first control channel, the UE sends the acknowledgement message on a second control channel in a sub-frame following the measurement gap. The first control channel is associated with the second control channel.

Abstract: A system acquisition is initiated to perform inter radio access technology (IRAT) measurement. A waiting period of time is provided before aborting the system acquisition. The period of time is adjustable based on at least one metric. The metric can be a frequency of available measurement gaps, a total number of available measurement gaps, and/or a length of each measurement gap within a subframe. The metric could also be an absolute signal strength of a single neighbor cell and/or a relative signal strength between neighbor cells. The metric could also be a user equipment (UE) measured signal strength compared to a network indicated threshold value for triggering an IRAT measurement report. The metric could also be a percentage of a tone that falls within a measurement gap.

Abstract: In a system and method for wireless communication, a user equipment (UE) is configured to determine whether it failed to detect and decode a data transmission while the UE tuned away from a first RAT to a second RAT based on a grant sequence number. The HARQ buffer is flushed when the UE determines it missed a grant and the duration of the tune away gap meets a particular criteria.

Abstract: An early BSIC (base station identity code) abort procedure includes comparing a first signal strength of a serving cell with a first threshold and comparing a second signal strength of a target cell to a second threshold. The first threshold is a sum of a network indicated threshold and a user equipment (UE) threshold. The second threshold is a difference between the network indicated threshold and the UE threshold. When the first signal strength is below the first threshold and the second signal strength is above the second threshold, the base station identity code (BSIC) procedure is initiated. A number of BSIC failure attempts is adaptively set before terminating the BSIC procedure.
