Abstract: Methodologies are described that facilitate inter-eNode B handover. In various embodiments, logical protocol termination can be implemented between the user equipment and the target eNode B for inter-eNode B handover signaling. The provided handover forwarding and encapsulation mechanisms enable improved inter-operability between eNode Bs implementing different protocol versions or from different vendors, which in turn enables frequent protocol upgrades. Additionally, the invention enables the target eNode B to implement new radio configurations even if the configuration is unsupported by the source eNode B.

Abstract: Measurements are conducted on one or more carriers in a case where an access terminal supports reception on multiple carriers. Upon determining that an access terminal is capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while receiving on or more other carriers of the set. Conversely, upon determining that an access terminal is not capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while not receiving on or more other carriers of the set. In addition, data transfers to or from an access terminal on a carrier may be restricted (e.g., data transfers not scheduled or only low priority data transfers scheduled) during one or more subframes before or after the access terminal conducts a measurement on another carrier.

Abstract: Methods and apparatuses for re-synchronizing Cell Radio Network Temporary Identifiers (C-RNTIs) in a wireless communication system are disclosed. In an aspect, a random access preamble is sent for random access by a user equipment (UE) and a random access response (RAR) is received that includes a temporary C-RNTI. If the UE already has a valid C-RNTI, a message is sent that includes the valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for the UE. In another aspect, a random access preamble for random access is received and a RAR is sent that includes a temporary C-RNTI. A message is received that includes a valid C-RNTI instead of the temporary C-RNTI as a C-RNTI for a UE if the UE already has the valid C-RNTI.

Abstract: The base station may receive a first indication that the UE supports NR-CA with multiple PUCCH groups or NR-DC with multiple cell groups and a second indication that the UE does not support simultaneous Rx/Tx in a first frequency band and a second frequency band, and schedule communication with the UE to avoid scheduling the simultaneous Rx/Tx based on the first and second indications. The base station may avoid scheduling simultaneous Rx/Tx in a first cell group or a first PUCCH group including the first frequency band and a second cell group or a second PUCCH group including the second frequency band. The UE may skip reporting to the base station that the UE supports the NR-DC or the NR-CA with the first frequency band and the second frequency band.

Abstract: Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a calibration to improve the accuracy, reliability, or both of signal transmissions. The UE may determine timing for the calibration procedure based on a received identifier for the UE (e.g., a radio network temporary identifier (RNTI), such as a cell RNTI (C-RNTI)). For example, the UE may determine a calibration offset between a reference time and a calibration gap according to an equation using at least the identifier as input. During the calibration gap, the UE may transmit a calibration signal using one or more antenna ports and may calibrate (e.g., adjust power amplification for) the one or more antenna ports based on an estimated actual transmit power for the calibration signal (e.g., received by other antenna ports of the UE or received by another device).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a frequency associated with a synchronization signal block (SSB) associated with a base station. The UE may generate a security key associated with a handover of the UE based at least in part on the frequency associated with the SSB. Numerous other aspects are provided.
