Abstract
User equipment includes a receiver that communicates with a base station apparatus, and that receives, from the base station apparatus, one or more blocks associated with one or more beams transmitted from the base station apparatus, the one or more blocks including information used for initial access; a controller that selects a block used for determining a resource for transmitting a preamble from the one or more blocks, based on received power or reception quality of the one or more beams; and a transmitter that transmits the preamble to the base station apparatus using the resource.
Claims5
A terminal comprising:
- a receiver that receives, from a base station apparatus, one or more synchronization signal blocks associated with one or more beams transmitted from the base station apparatus, the one or more synchronization signal blocks including information on initial access;
- a controller that selects a synchronization signal block used for determining a resource for transmitting a preamble from the one or more synchronization signal blocks, based on at least one of received power or reception quality of the one or more synchronization signal blocks;
- and
- a transmitter that transmits the preamble to the base station apparatus using the resource,
- wherein if information included in the selected synchronization signal block indicates that the cell is restricted, the controller excludes the synchronization signal block from candidates of the synchronization signal block used for the initial access.
A communication method executed by a terminal, the method comprising:
- receiving, from a base station apparatus, one or more synchronization signal blocks associated with one or more beams transmitted from the base station apparatus, the one or more synchronization signal blocks including information on initial access;
- selecting a synchronization signal block used for determining a resource for transmitting a preamble from the one or more synchronization blocks, based on at least one of received power and received quality of the one or more synchronization signal blocks;
- and
- transmitting the preamble to the base station apparatus using the resource,
- wherein if information included in the selected synchronization signal block indicates that the cell is restricted, excluding the synchronization signal block from candidates of the synchronization signal block used for the initial access.
A radio communication system comprising:
- a terminal;
- and
- a base station apparatus,
- wherein the base station apparatus includes a transmitter that transmits one or more synchronization signal blocks associated with one or more transmitted beams, the one or more synchronization signal blocks including information on initial access;
- wherein the terminal includes
- a receiver that receives, from the base station apparatus, the one or more synchronization signal blocks associated with the one or more beams transmitted from the base station apparatus, the one or more synchronization signal blocks including the information on initial access;
- a controller that selects a synchronization signal block used for determining a resource for transmitting a preamble from the one or more synchronization blocks, based on at least one of received power and received quality of the one or more synchronization signal blocks;
- and
- a transmitter that transmits the preamble to the base station apparatus using the resource, and
- wherein if information included in the selected synchronization signal block indicates that the cell is restricted, the controller excludes the synchronization signal block from candidates of the synchronization signal block used for the initial access.
