Abstract: Certain aspects of the present disclosure relate to methods and apparatus for enhanced user equipment (UE) capability exchange for transitioning a connection from a first radio access technology system to a second radio access technology system. An exemplary method performed by a UE includes communicating with a first base station (BS) via a connection of a first radio access technology (RAT), determining, based on the first RAT, to omit a set of capabilities of the UE from capabilities information of the UE regarding a second RAT, transmitting the capabilities information of the UE regarding the second RAT to the first BS via the first RAT, communicating with a second BS via the second RAT according to the capabilities information, and sending an update of the capabilities information of the UE regarding the second RAT via the second RAT.

Abstract: Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

Abstract: Techniques for optimized cell acquisition for long term evolution (LTE) time division duplex (TDD) systems or closed subscriber group (CSG)/evolved Multicast Broadcast Multimedia Service (eMBMS) capable user equipments (UEs) are disclosed. A UE obtains configuration information, CSG capability information, and/or eMBMS capability information for a cell. The UE also stores the obtained information for the cell in a cell information database. In some aspects, the UE may employ the CSG and/or eMBMS capability information to select a weaker cell, during initial frequency scan at power up of the UE, based on cell capability. Additionally or alternatively, the UE may employ the configuration information to determine an initial mutual information (Mi) hypothesis value for physical hybrid-automatic repeat request (HART) indicator channel (PHICH) group mapping of the cell. Additionally or alternative, radio link failures and/or out of synch events may be predicted and proactive responses employed based on previously obtained solutions.

Abstract: Aspects relate to techniques for expediting New Radio (NR) cell addition in non-standalone (NSA) mode. The UE may receive a conditional handover (CHO) command from a first anchor cell operating a first frequency range (e.g., a Long Term Evolution (LTE) frequency range) that enables the UE to subsequently select a different anchor cell to which to perform a handover. The UE may then receive a deconfiguration from the first anchor cell of a measurement object for secondary cell addition in a second frequency range (e.g., a NR frequency range). Based on the CHO command and the deconfiguration of the measurement object, the UE may then perform a handover to a second anchor cell in the first frequency range to facilitate addition of at least one secondary cell in the second frequency range.

Abstract: Methods and mechanisms for performing idle mode mobility procedures are provided. According to one aspect of the present disclosure, a method for wireless communication performed by a user equipment (UE) includes: receiving, from a base station (BS) on a first cell, system information indicating a first cell reselection priority configuration; receiving, from the BS, dedicated signaling indicating a dedicated cell reselection priority configuration, wherein the dedicated cell reselection priority configuration is empty; and connecting, while in an idle mode and in response to the dedicated cell reselection priority configuration being empty, to a second cell different from the first cell based on the first cell reselection priority configuration received in the system information.

Abstract: Methods, systems, and devices for are described. A user equipment (UE) may be configured to initiate a first setup procedure with a first cell supported by a base station. The UE may determine a system information block (SIB) read failure, a radio link failure, or both, based on initiating the first setup procedure. The UE may determine whether a link quality metric associated with communications between the UE and the first cell satisfies a link quality threshold. The UE may select a cell bar time based on a type of a communications service established via the base station, whether the link quality metric satisfies the link quality threshold, or both. The UE may then initiate a cell reselection procedure based on the cell bar time.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a request to receive a Multimedia Broadcast Multicast Service (MBMS) service associated with a service area identity (SAI) and a second frequency. The apparatus performs inter-frequency cell reselection from a first cell transmitting at a first frequency to a second cell transmitting at the second frequency, the second cell being an inter-frequency neighbor cell to the first cell. The apparatus receives system information from the second cell. The apparatus determines that the second cell transmitting at the second frequency is unassociated with the SAI based on the received system information. The apparatus blacklists the SAI on the second frequency in a blacklist for at least a period of time upon determining that the second cell is unassociated with the SAI.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a first MTCH. The apparatus stores MBMS control information for at least a second MTCH. The apparatus subsequently determines to receive the second MTCH. The apparatus then accesses the stored MBMS control information for the second MTCH upon determining to receive the second MTCH. The apparatus receives the second MTCH based on the accessed MBMS control information without acquiring the MBMS control information for the second MTCH after the determination to receive the second MTCH.

Abstract: Techniques for optimized HARQ recombining are provided. In one exemplary embodiment, a method for wireless communication comprises receiving a broadcast message to determine a timing of a transmission window, receiving at least one transmission within the transmission window, and determining whether the at least one transmission is successfully decoded. The method further comprises instructing a lower protocol layer to ignore remaining transmissions within the transmission window upon a determination that the at least one transmission is successfully decoded, wherein the remaining transmissions and the at least one transmission comprise duplicate copies of a message segment.

Abstract: Methods and apparatuses are provided for managing a list of target frequencies for cell measurement. A set of available target frequencies for performing cell measurements from a serving cell can be received, and at least a subset of the set of available target frequencies can be prioritized based at least in part on a list of a plurality of target frequencies stored in a reselection database for the serving cell. Cell measurements can be performed based at least in part on at least the subset of the set of available target frequencies as prioritized. Additionally, the plurality of target frequencies in the reselection database may correspond to target frequencies to which successful reselection has occurred from the serving cell.
