    Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.

    Abstract: A multi-antenna device configured for addressing connection performance issues in UL/DL imbalance scenarios is described. The device may identify a potential UL/DL imbalance scenario and select signal measurements associated with either a primary antenna or a diversity antenna for mobility procedures and/or mobility measurement reporting based on the detected imbalance. In one example, the device may receive a signal at both the primary and a diversity antenna and may identify an imbalance between the primary and diversity signal measurements. The device may then compare the identified imbalance with an imbalance threshold and may select the primary or diversity signal measurement for mobility procedures and/or measurement reporting based at least in part on the comparison. For instance, if the imbalance is greater than the imbalance threshold the device may use the primary signal measurements and may otherwise use the stronger of the primary or diversity signal measurements.

    Abstract: Methods and apparatuses for wireless communication are provided. In some aspects, a user equipment (UE) may obtain a gain value based on a difference between an reference signal receive power (RSRP) value of a first antenna and an RSRP value of a second antenna, where the first antenna may be located on an exterior of the UE and the second antenna may be located within an interior of the UE. Further, in some aspects, the UE may obtain an antenna gain value based at least on a random access channel (RACH) power value and a reference signal receive quality (RSRQ) offset value. Additionally, in some aspects, the UE may obtain the antenna gain value based on one of a matching entry in a memory log or a minimum of a maximum antenna gain value or an aggregation of a RACH gain value and an RSRQ offset value.

    Abstract: A method for cell reselection by a wireless communication device is described. The method includes signal strength of cells in one or more inter-radio access technology (inter-RAT) frequencies while camped on a serving cell in a connected mode. On releasing the connected mode and before moving to idle mode on the serving cell, the method also includes prioritizing the cells in the one or more inter-RAT frequencies based on a RAT preference order and the signal strength. The method further includes reselecting to a highest priority cell whose signal strength meets a cell selection criterion.
