Abstract
A communication method applied to an integrated access and backhaul (IAB) system includes: a child node receives a first radio resource control (RRC) reconfiguration message from an access network device via a parent node, where the first RRC reconfiguration message includes a random access-free indication. The child node starts a timer. The child node sends a first RRC reconfiguration complete message to the access network device via the parent node. The child node receives first indication information from the parent node, where the first indication information indicates to stop the timer. The child node stops the timer.
Claims20
A communication apparatus in an integrated access and backhaul (IAB) system, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and configured to store executable instructions for execution by the at least one processor to instruct the at least one processor to:
- receive a first radio resource control (RRC) reconfiguration message from an access network device via a parent node, wherein the first RRC reconfiguration message comprises a random access-free indication;
- start a timer;
- send a first RRC reconfiguration complete message to the access network device via the parent node;
- receive first indication information from the parent node, wherein the first indication information indicates to stop the timer;
- and
- stop the timer.
A communication apparatus in an integrated access and backhaul (IAB) system, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and configured to store executable instructions for execution by the at least one processor to instruct the at least one processor to:
- receive a first radio resource control (RRC) reconfiguration message from an access network device, wherein the first RRC reconfiguration message comprises a random access-free indication;
- send the first RRC reconfiguration message to a child node, to trigger the child node to start a timer;
- receive a first RRC reconfiguration complete message from the child node;
- send the first RRC reconfiguration complete message to the access network device;
- and
- send first indication information to the child node, wherein the first indication information indicates to stop the timer.
A communication apparatus in an integrated access and backhaul (IAB) system, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor and configured to store executable instructions for execution by the at least one processor to instruct the at least one processor to:
- send a first radio resource control (RRC) reconfiguration message to a child node via a parent node, so as to trigger the child node to start a timer, wherein the first RRC reconfiguration message comprises a random access-free indication;
- receive a first RRC reconfiguration complete message from the child node via the parent node;
- and
- send second indication information to the parent node, so as to trigger the parent node to send first indication information to the child node, wherein the first indication information indicates to stop the timer.
