A base station receives RRC message(s) comprising configuration parameters for a LAA cell. The configuration parameters comprise one or more SRS parameters. Configuration parameters of cells are transmitted to a wireless device. The cells are grouped into timing groups. The cells are grouped into control channel groups comprising: a primary control channel group; and a secondary control channel group comprising a control secondary cell with a secondary control channel received from the wireless device. The control secondary cell is in a first timing group of the timing groups. In response to expiration of a time alignment timer of the first timing group: transmission of downlink shared channel transport blocks to the wireless device via a first secondary cell in the secondary control channel group are stopped; and transmission of downlink multicast channel transport blocks to the wireless device via the first secondary cell is continued.

Apparatuses, methods, and systems are disclosed for uplink transmission blanking. One apparatus (200) includes a receiver (212) that: receives (602) a first signal from a base unit, wherein the first signal is used for indicating scheduling information for a first uplink transmission; and receives (604) a third signal from the base unit. The third signal is used for determining a first one or more symbols of the first uplink transmission to be blanked. The apparatus (200) also includes a processor (202) that determines (606) the first one or more symbols of the first uplink transmission to be blanked based on the third signal. The apparatus (200) includes a transmitter (210) that transmits (608) the first uplink transmission to the base unit with the first one or more symbols blanked.

Example communication methods and apparatus are described. One example method includes sending a first handover request by a source base station to a core network device, where the first handover request is used to request to hand over a current session of a terminal from the source base station to any one of at least one base station, and the first handover request includes information about the at least one base station. The source base station receives a first handover response message from the core network device, where the first handover response message includes indication information, and the indication information is used to indicate whether a first base station of the at least one base station supports a network slice corresponding to the current session of the terminal device.

Fifth generation (5G) non-standalone (NSA) radio access system employing virtual fourth generation (4G) master connection to enable dual system data connectivity. The 5G NSA radio access system employs a virtual 4G radio access node (RAN) to provide a logical master data connection to a user mobile communications device, and a 5G RAN to provide an additional, secondary high-speed data plane between the user mobile communications device to a core network. The virtual 4G RAN does not provide an actual 4G radio connection over-the-air to the user mobile communications device. Instead, the signaling transported between the user mobile communications device and the virtual 4G RAN is provided over a non-radio connection, such as an internet protocol (IP) connection. In this manner, the deployment of the 5G NSA radio access system employing the virtual 4G RAN can be achieved without updating existing 4G RANs and/or without deploying a new 4G RAN infrastructure.

A method for enhancing network coverage based on adaptive generation of resource cell. A traditional cell in a network is taken as an initial state of the network. A correlation matrix in a current network state is generated. Whether |ω.sub.i,j.sup.t−ω.sub.i,j.sup.t-1|/ω.sub.i,j.sup.t-1>ε is determined. Each access point is divided into a plurality of resource cells. A CU-DU network mapping table is generated. A middlehaul link of each of the plurality of resource cells is constructed according to the CU-DU network mapping table.
