In aspects, a base station and a user equipment (UR) exchange synchronization signal blocks (SSBs) carrying a SFN identity, and a waveform of the SSBs has a secondary synchronization signal (SSS) symbol preceding a primary SS symbol. In aspects, a base station transmits a radio access network area code (RAN-AC) SS and RAN-AC page are quasi co-located (QCL). In aspects, a base station transmits a RAN-AC SS over a SFN while avoiding overlap of RAN-AC SS resources with channels employed for initial access of update area cells. In aspects, a base station provides a control resource set (CORESET) to a UE upon release from a connected slate, and the UR receives a RAN-AC paging PDCCH based on the CORESET. In aspects, a base station transmits a SFN wake up signal (WUS) when there is a grant for paging, and the UK monitors for the WUS.

An operation method of a communication node transmitting a synchronization signal in a communication network may comprise generating a synchronization signal block including the synchronization signal; configuring an offset for the synchronization signal block; generating a synchronization signal burst including a plurality of the synchronization signal blocks based on the offset; and transmitting the synchronization signal based on a synchronization signal burst set including the plurality of the synchronization signal blocks. Accordingly, a terminal can dynamically and effectively utilize the plurality of synchronization signal blocks without using additional information.

Methods, apparatuses, and systems are described for wireless communications. A transmission timing difference between a first cell group and a second cell group may be determined. If the transmission timing difference exceeds a threshold, one or more devices may stop transmitting uplink signals via one or more secondary cells and/or may not apply the timing adjustment for a cell group.

Methods and apparatuses are described for wireless communications. Cells may be grouped into a plurality of cell groups. Time alignment timers may be associated with cell groups. A wireless device may perform/continue/stop transmissions based on the time alignment timers.

Methods, apparatuses, and systems are described for wireless communications. A wireless device may determine a first transmission power for a first signal and a second transmission power for a second signal. Based on a calculated transmission power and an overlap of the signals, a power control mechanism may be employed.

A method for converting a conventional cellular network e.g. having nodes equipped with conventional modems operating in accordance with a cellular communication protocol e.g. LTE and storing first orthogonal sequences, into a private cellular network, including coupling an (e.g. external) device to only nodes sought for the private cellular network, the device storing second orthogonal sequences not hard-coded in the modems, the device storing a one-to-one correspondence enabling translation of each second orthogonal sequence, to one of the first sequences. at least when in a private network supporting mode, a device associated with a transmitting node sought for the private network, uses a processor to determine which first orthogonal sequence is being used, translate that sequence using the one-to-one correspondence into a second orthogonal sequence, and use the translated sequence to transmit a synchronization signal.

A base station can select orthogonal frequency-division multiplexing (OFDM) numerologies that define subcarrier spacing values based on attributes associated with one or more services that a user equipment (UE) is using. The base station can use the selected OFDM numerologies for transmission associated with the services. When the UE is using multiple services simultaneously, the base station can select the same or different OFDM numerologies for the multiple services.

A base station may identify an association between a set of physical cell identifiers (PCIs) identifying different transmission reception points (TRPs) and a set of transmission configuration indicator (TCI) states for a user equipment (UE). The base station may transmit a TCI state and PCI association indication to the UE. The UE may receive a downlink transmission using a receive beam associated with a TCI state, and may identify a PCI of the set of PCIs to use to decode the received downlink transmission. In cases where the TCI state used to receive the downlink transmission is associated with multiple PCIs, the UE may select a default PCI from the multiple PCIs, and may decode the received transmission accordingly. In some examples, the UE may receive reference signals from one or more of the serving TRPs and may identify a PCI to use to decode the received reference signals.

Methods, apparatuses, and systems are described for wireless communications. At least one control message comprising a plurality of configuration parameters for a plurality of random access channel resources may be transmitted to a wireless device. The wireless device may transmit a preamble via at least one of the plurality of random access channel resources.

A wireless device receives at least one control message comprising configuration parameters of a plurality of cells grouped into at least a first cell group and a second cell group. The first cell group comprises a first reference cell. The second cell group comprises a second reference cell. The at least one control message comprises a pathloss reference for a secondary cell in the second cell group. The pathloss reference is configurable to one of a) a downlink of the second reference cell and b) a downlink of the secondary cell.
