Wireless communications may use a plurality of cell groups. A downlink-uplink cell may be assigned to each cell group of a plurality of cell groups, and each of a plurality of downlink-only cells may be assigned to a cell group of the plurality of cell groups. A wireless device may transmit an uplink signal via a downlink-uplink cell based on a timing advance command.

A set of reference signals can be received. Each of the set of reference signals can be periodically transmitted by a network entity. Information of a plurality of random access channel preambles and a plurality of reference signals from the set of reference signals can be received via a dedicated radio resource control message. At least one reference signal of the plurality of reference signals can be detected. A reference signal can be selected from the detected at least one reference signal. A random access channel preamble of the plurality of random access channel preambles can be transmitted in a contention-free random access procedure. The random access channel preamble for transmission can be determined based on the selected reference signal.

Provided are a method and device for determining transmission power, a terminal and a storage medium. The method includes measuring a first reference signal and determining a pathloss of the first reference signal; determining a pathloss of the uplink transmission according to a type of the uplink transmission, an association relationship between the uplink transmission and the first reference signal, and the pathloss of the first reference signal; determining an power adjustment amount of the uplink transmission; and determining the transmission power of the uplink transmission according to at least one of the pathloss of the uplink transmission or the power adjustment amount of the uplink transmission.

A method includes receiving, at a mobile device, resource pool configuration information, the resource pool configuration information comprising a bitmap to determine the resource pool and determining, for a period having a plurality of consecutive subframes, a first subset of subframes by excluding, from the plurality of consecutive subframes, subframes in which a sidelink synchronization signal (SLSS) resource is configured and subframes other than uplink subframes. The method also includes determining, for the period, a second subset of subframes by excluding, from the first subset of subframes, one or more subframes, wherein a quantity of the second subset of subframes corresponds to an integer multiple of a length of the bitmap, and determining, based on a plurality of repetitions of the bitmap, the resource pool for a sidelink transmission from the second subset of subframes.

A base station central unit transmits, to a wireless device via a base station distributed unit, configuration parameters of the wireless device. The base station central unit receives, from the wireless device via the base station distributed unit, a confirmation of at least one of the configuration parameters. The base station central unit transmits, to the base station distributed unit, an indication that the wireless device successfully performed a reconfiguration procedure based on the configuration parameters. The base station central unit communicates, with the wireless device via the base station distributed unit, based on the configuration parameters.

A wireless device receives configuration parameters of cells grouped into timing advance groups (TAGs). The cells comprise: downlink-uplink cells, each of the downlink-uplink cells having a configured uplink and a configured downlink; and at least one downlink-only cell, each of the at least one downlink-only cell having a configured downlink with no configured uplink. A TAG is configurable to consist of one or more downlink-only cells in response to the wireless device having a first capability, otherwise each TAG comprises one or more downlink-uplink cells in the downlink-uplink cells. At least one timing advance command (TAC) for a first TAG is received. The TAC is applied to uplink transmission timing of at least one downlink-uplink cell in the first TAG.

A wireless receiver includes a guided user interface to enable and assist users to optimally select groups and frequencies for wireless communication with wireless transmitters is provided. The wireless receiver may automatically detect the connectedness and parameters of wireless receivers in order to adaptively display and select setup options and messages. The guided user interface may improve user satisfaction and reduce the configuration time of the wireless receivers.

Devices, systems and methods for implementing beam failure management techniques at a user equipment (UE). The UE receives a timing advance command (TAC) from a currently camped cell and initiates a time advance timer (TAT). When the TAT is running the UE is in a first operating state. The first operating state indicates that the UE is in time alignment with the cell. The UE identifies that the TAT has expired. When the TAT is not running the UE is in a second operating state. The second operating state indicates that the UE is not in time alignment with the cell. The UE implements one or more beam failure management techniques based on the UE operating in the second operating state.

A wireless device may receive at least one control message. The at least one control message may comprise at least one pathloss reference parameter that may indicate a downlink carrier.

Aspects of the disclosure generally relate to wireless communication. In some aspects, a wireless node may identify a first set of synchronization signal blocks (SSBs), within a synchronization signal (SS) burst set, that are used to indicate random access channel (RACH) occasions for a first wireless link type, the SS burst set including a second set of SSBs used to indicate RACH occasions for a second wireless link type; and transmit a RACH message in a RACH occasion corresponding to an SSB included in the first set of SSBs. In some aspects, a wireless node may configure an SS burst set to include a first set of SSBs to be used to indicate RACH occasions for a first wireless link type, and a second set of SSBs to be used to indicate RACH occasions for a second wireless link type; and transmit the SS burst set. Other aspects are provided.
