REPEATING METHOD AND DEVICE OF ACCESS LINK OF REPEATER
A network controlled repeater (NCR) includes: a NCR-MT (Mobile Termination) processor circuitry configured to receive a beam index of an access link from a network device; and a NCR-Fwd (Forwarding) processor circuitry configured to perform forwarding on the access link by using a beam to which a received beam index corresponds.
1 . A network controlled repeater (NCR), comprising:
a NCR-MT (Mobile Termination) processor circuitry configured to receive a beam index of an access link from a network device; and
a NCR-Fwd (Forwarding) processor circuitry configured to perform forwarding on the access link by using a beam to which a received beam index corresponds.
2 . The network controlled repeater according to claim 1 , wherein,
the beam index received by the repeater is indicated by at least one of RRC (Radio Resource Control) signaling, an MAC CE (Control Element) and physical layer signaling.
3 . The network controlled repeater according to claim 1 , wherein,
the beam index received by the repeater is at least one of beam indexes of an access link configured by the network device.
4 . The network controlled repeater according to claim 2 , wherein,
the beam index received by the repeater comprises a first beam index configured by the network device or reported by the repeater indicated by the network device, and a second beam index configured via RRC signaling and activated via an MAC CE and indicated by a domain of physical layer signaling by the network device.
5 . The network controlled repeater according to claim 4 , wherein,
a beam of the repeater for receiving semi-static beam configuration corresponds to the first beam index indicated by the network device, and a beam of the repeater for receiving dynamic beam configuration corresponds to the second beam index indicated by the network device.
6 . The device according to claim 1 , wherein,
the beam index received by the repeater is indicated a corresponding beam index by a first number of bits.
7 . The device according to claim 6 , wherein for the case where the beam index received by the repeater is indicated a corresponding beam index by a first number of bits,
the first number is determined by a total number of beam indexes of the access link.
8 . A network device, comprising:
a transmitter configured to indicate a beam index of an access link to a network controlled repeater (NCR).
9 . The network device according to claim 8 , wherein,
the network device indicates the beam index of the access link via at least one of RRC signaling, an MAC CE (Control Element) and physical layer signaling.
10 . The network device according to claim 8 , wherein,
the network device indicates at least one of beam indexes of the access link configured by the network device to the repeater.
11 . The network device according to claim 9 , wherein,
the beam index indicated by the network device comprises a first beam index configured by the network device, and a second beam index configured via RRC signaling and activated via an MAC CE by the network device and indicated by a domain of physical layer signaling.
