Abstract
A method comprising: providing a user equipment (UE) with one or more restrictions, in addition to a timer, for limiting the UE to send on-demand System Information Block (SIB) requests regarding reference signal configurations for Radio Resource Control (RRC) Idle/Inactive UE mode; receiving an on-demand SIB request regarding reference signal configurations for RRC Idle/Inactive UE from the user equipment; and sending a reference signal configuration SIB to the user equipment.
Claims20
An apparatus comprising:
- a processor;
- a non-transitory computer-readable medium comprising computer-executable instructions that, when executed by the processor, cause the processor to perform the following operations:
- receiving restrictions limiting the apparatus to send on-demand system information block (SIB) requests regarding tracking reference signal and channel state information reference signal (TRS/CSI-RS) configurations for radio resource control (RRC) Idle or Inactive mode, wherein if all of the restrictions are not fulfilled, the apparatus is prohibited from sending the request for on-demand SIBs regarding TRS/CSI-RS configurations for RRC Idle or Inactive mode, and wherein the restrictions comprise the following:
- a threshold time for the apparatus to be associated with at least one cell or beam before allowing to send an on-demand SIB request, the threshold time for the apparatus comprising a dynamically changing group of beams to be attached to, the group of beams being used for cell measurement operations, and wherein the threshold time is associated with at least one unchanged beam;
- a maximum number of cell reselections or beam switches within a predetermined period for being allowed to send the on-demand SIB request;
- a minimum time for the apparatus estimated to remain associated with the at least one cell or beam;
- a maximum threshold value for a mobility of the apparatus, wherein the maximum threshold value for the mobility of the apparatus being defined based on a mobility state of the apparatus;
- a maximum variation in reference signal received power (RSRP) value;
- receiving a timer that prohibits the apparatus from sending the SIB requests regarding the TRS/CSI-RS configurations for RRC Idle or Inactive mode while the timer is running;
- storing the restrictions and the timer in the non-transitory computer-readable medium;
- determining that all of the restrictions are satisfied;
- based on determining that all of the restrictions are satisfied, sending an on-demand SIB request regarding TRS/CSI-RS configurations for RRC Idle or Inactive mode to a network element;
- upon sending the SIB request regarding TRS/CSI-RS configurations for RRC Idle or Inactive mode to the network element, starting the timer,
- upon receiving, from the network element, a reference signal configuration SIB, stopping the timer;
- and
- upon stopping the timer, transferring the apparatus from RRC Idle or inactive mode to RRC connected mode.
