Abstract
A cellular communication system comprises a first base station serving at least a first user equipment. The base station comprises functionality for transmitting a base station duplex capability message to user equipments using a transmission format which is common to a plurality of duplex modes. A first user equipment comprises a transceiver which receives the base station duplex capability message. A RACH characteristics processor determines at least one transmit characteristic for an access message in response to the base station duplex capability message and a RACH transmit controller controls the transmission of an access message to the first base station in response to the at least one transmit characteristic.
Claims20
An electronic device comprising:
- circuitry configured to
- broadcast duplex capability information to user equipment using a common transmission format that is common for both a full duplex mode and a half duplex mode supported by the electronic device, wherein the duplex capability information includes information indicating at least one of the full duplex mode and the half duplex mode;
- and
- receive an access request message requesting to initially attach to a network transmitted by the user equipment in response to the duplex capability information.
An communication apparatus comprising:
- an antenna;
- and
- circuitry configured to
- broadcast duplex capability information to user equipment using a common transmission format that is common for both a full duplex mode and a half duplex mode supported by the electronic device, wherein the duplex capability information includes information indicating at least one of the full duplex mode and the half duplex mode;
- and
- receive an access request message requesting to initially attach to a network transmitted by the user equipment in response to the duplex capability information.
A method performed by an electronic device, the method comprising:
- broadcasting duplex capability information to user equipment using a common transmission format that is common for both a full duplex mode and a half duplex mode supported by the electronic device, wherein the duplex capability information includes information indicating at least one of the full duplex mode and the half duplex mode;
- and
- receiving an access request message requesting to initially attach to a network transmitted by the user equipment in response to the duplex capability information.
An electronic device comprising:
- circuitry configured to
- receive, from a base station, a broadcast message regarding duplex capability of the electronic device, the broadcast message using a common transmission format that is common for both a full duplex mode and a half duplex mode supported by the electronic device,
- transmit duplex capability information to the base station using control channel, the duplex capability information indicating at least one of the full duplex mode and the half duplex mode,
- transmit an access request message requesting to initially attach to a network using at least one of the full duplex mode and the half duplex mode indicated by the duplex capability information.
An electronic device comprising:
- circuitry configured to
- receive, from a base station, a broadcast message regarding whether the electronic device supports at least one of a full duplex mode and a half duplex mode, the broadcast message using a common transmission format that is common for both the full duplex mode and the half duplex mode supported by the electronic device;
- and
- transmitting duplex capability information to the base station using an access request message requesting to initially attach to a network.
