Initiating random access in a target cell in a non-terrestrial network
摘要
說明書
The following provides an overview of some Aspects of the present disclosure:
Aspect 1: A method of wireless communication performed by a UE, comprising: receiving information configuring a target cell monitoring window in an NTN; detecting one or more events that trigger a RACH procedure in a target cell in the NTN; monitoring a control channel from the target cell for a control signal that includes an indication to initiate the RACH procedure in the target cell, wherein the control channel is monitored based at least in part on detecting the one or more events that trigger the RACH procedure in the target cell; and transmitting a random access message that includes a preamble to initiate the RACH procedure in the target cell, wherein the random access message is transmitted at a time that is based at least in part on a status associated with the control signal.
Aspect 2: The method of Aspect 1, further comprising: receiving, on the control channel during the target cell monitoring window, the control signal that includes the indication to initiate the RACH procedure, wherein the random access message is transmitted during the target cell monitoring window based at least in part on receiving the control signal.
Aspect 3: The method of any of Aspects 1-2, wherein the control signal includes DCI that activates one or more resources in the target cell that are reserved for initiating the RACH procedure by the UE or UEs in a UE group that includes the UE.
