Abstract: The present disclosure relates to methods, devices and software that can be used for preventing damage to RF front end equipment used in wireless communication systems. In some aspects, a user equipment (UE) may establish a first communication having a first priority, wherein the first communication is associated with a first subscriber in a connected mode. The UE may establish a second communication having a second priority, wherein the second communication is associated with a second subscriber in the connected mode. The UE may identify a state of a transmit/receive (TRX) switch shared between the first communication and the second communication. The UE may perform, based at least in part on the state of the TRX switch, at least one of the first communication or the second communication using a TRX switching configuration.

Abstract: Apparatus, methods, and computer-readable media for facilitating managing multi-SIM concurrent mode for TDD co-banded or spectrum overlap carriers are disclosed herein. An example method for wireless communication at a user equipment (UE) includes estimating a maximum transmit power for a first subscriber based on a low-noise amplifier (LNA) input power threshold associated with an active receive chain of a second subscriber, where the UE comprises the first subscriber and the second subscriber. The example method also includes transmitting, via an active transmit chain of the first subscriber, an uplink transmission at the first subscriber maximum transmit power based on the first subscriber and the second subscriber operating concurrently, and a transmit power associated with the uplink transmission being greater than the first subscriber maximum transmit power.

Abstract: An apparatus may operate in a dual connectivity mode in which the apparatus is simultaneously connected to carriers of different radio access technologies. The apparatus may operate via a first antenna set of a plurality of antenna sets, the first antenna set including a first communication path. The apparatus may determine to operate via a second antenna set of the plurality of antenna sets based on whether one or more criteria is satisfied. The apparatus may select at least one second communication path for the second antenna set based on the one or more criteria. The apparatus may operate via the second antenna set over the at least one second communication path when the criteria is satisfied.

Abstract: The present disclosure provides a method, apparatus, and computer-readable medium that is able to avoid ping pong mobility when a redirection procedure fails. The apparatus may attempt to perform a redirection procedure from a first RAT to a target frequency of a second RAT. The apparatus may receive a redirection failure notification indicating that the target frequency of the second RAT is unavailable. The apparatus may refrain from initiating a reselection procedure to the target frequency of the second RAT for a predetermined time period. The apparatus may deprioritize the target frequency of the second RAT for the predetermined time period when the target frequency of the second RAT is unavailable and is present in an SIB received from the neighbor cell. The apparatus may generate a list of banned frequencies that includes the target frequency of the second RAT when the target frequency of the second RAT is unavailable.

Abstract: A user equipment (UE) enables reselection by supplementing dedicated priority information received from a network with proprietary priority-based reselection parameters stored in a UE memory. The reselection is performed when a currently camped-on cell does not broadcast priority-based reselection parameters. The proprietary priority-based reselection parameters include threshold parameters such as high priority thresholds, low priority thresholds, signal strength thresholds and related reselection timers.

Abstract: A user equipment (UE) prioritizes searches and/or measurements of neighbor cells/frequencies based on a level of mobility of a UE. In one instance, the UE identifies a priority of a layer of a radio access technology (RAT) to be measured or searched and identifies a level of mobility of the UE. A sensor module of the UE may determine the level of mobility of the UE and generate an indication corresponding to the level of mobility of the UE. The UE prioritizes a periodicity of interlayer search and/or measurement based on the priority of the layer to be measured and the level of the mobility of the UE.

Abstract: A user equipment (UE) reselects back to a higher priority radio access technology (RAT) when network configured parameters do not provide sufficient time to perform the IRAT reselection measurements and evaluation due to the UE spending a very short duration in a discontinuous reception (DRX) mode. In one instance, the UE detects a triggering condition for incomplete cell reselection evaluation based on a number of past events. The UE computes a modified reselection timer value based on the past events and applies the modified reselection timer value to future events.

Abstract: A base station may allocate served user equipments (UEs) into measurement gap groups, which are configured to reduce the overlap between UE measurement gaps used for inter-RAT measurement. The base station may configure the measurement gap groups based on an offset between subframes of a served and measured RAT and may distribute UEs in the measurement gap groups to avoid overlapping inter-RAT measurement times, thereby reducing idle base station resources.

Abstract: The present disclosure presents a method and an apparatus for inter radio access technology (IRAT) cell reselection. For example, the method may include identifying that a user equipment (UE) in an idle or a discontinuous reception (DRX) mode is camped on a cell of a first RAT, determining that the cell the UE is camped on is not broadcasting any neighbor cell of a second RAT, scanning for one or more frequencies of the second RAT based on the determination, and triggering a cell reselection to a cell of the second RAT, wherein the cell of the second RAT is associated with a frequency identified during the scanning. As such, an autonomous IRAT cell reselection may be achieved.
