Abstract: Embodiments disclosed herein include: (1) a network (e.g., a 5G New Radio (NR) network) that is configured to use Early Measurement Report (EMR) results reported from a User Equipment (UE) device to configure or change a Secondary Cell Group (SCG) for the UE; (2) a network configured to use service-specific frequency layer configuration information to configure the EMR feature for a UE; (3) a UE configured to use crowdsourced frequency layer information to autonomously determine the UE's EMR feature; (4) a UE configured to autonomously report Idle mode measurements without waiting for network-initiated messaging; (5) a UE configured to receive a set of Primary Secondary Cells (PSCells) from a network including an active PSCell and one or more deactivated PSCells; and (6) a network configured to use service-specific frequency layer configuration information and a list of potential PSCells to configure the EMR feature for a UE and activate a PSCell.

Abstract: Methods, systems, and computer-readable mediums are configured to perform operations including detecting a plurality of synchronization signal blocks (SSBs) that are transmitted for a physical broadcast channel (PBCH), each of the SSBs having a SSB index comprising a set of bit values; detecting, from the plurality of SSBs, a first SSB received at a first time and a second SSB received at a second time that is different from the first time; decoding, for a first SSB of the plurality, first bit values of a first SSB index representing the first SSB and of a second SSB index representing the second SSB; determining, based on the first time and the second time, a receive time gap between the first SSB and the second SSB; and determining, based on the receive time gap and the first bit values of the first SSB index and the second SSB index, at least a second bit value of the first second SSB index representing the first SSB and the second SSB representing the second SSB.

Abstract: Methods, apparatuses, systems, and computer programs for ciphering information in a physical layer of a wireless communications network are disclosed. In one aspect, a method can include obtaining, by a UE, a transport block for transmission using the physical layer, determining, by the UE, whether the size of the transport block satisfies a predetermined threshold, and based on a determination, by the UE, that the size of the transport block satisfies a predetermined threshold size: ciphering, by the UE, the entire transport block, and transmitting, by the UE and to an access node, the ciphered transport block using the physical layer.

Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).
