TIMING ADVANCE MANAGEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18305257 titled 'TIMING ADVANCE MANAGEMENT

Simplified Explanation

The patent application is about a method and apparatus for managing timing advance and beam management in a wireless communication system. Here is a simplified explanation of the abstract:

  • The method involves a UE (User Equipment) receiving a second TAG ID and a PDCCH order from a first BS (Base Station).
  • Upon receiving the PDCCH order, the UE initiates a CFRA (Channel Frequency Reuse Area) procedure.
  • The UE then transmits a RA (Random Access) preamble to a second BS.
  • The UE receives a TAC (Tracking Area Code) from the second BS, which is included in a RAR (Random Access Response) or a MAC CE (Medium Access Control Control Element).
  • The UE applies the received TAC and starts a second time alignment timer corresponding to the second TAG ID associated with the second BS.

Bullet points to explain the patent/innovation:

  • The patent application describes a method for managing timing advance and beam management in a wireless communication system.
  • The method involves a UE receiving a second TAG ID and a PDCCH order from a first BS.
  • The UE initiates a CFRA procedure in response to the received PDCCH order.
  • The UE then transmits a RA preamble to a second BS.
  • The UE receives a TAC from the second BS, which is included in a RAR or a MAC CE.
  • The UE applies the received TAC and starts a second time alignment timer corresponding to the second TAG ID associated with the second BS.


Original Abstract Submitted

Methods and apparatuses for a timing advance management for multi-TRP and beam management in a wireless communication system. A method of a UE comprises: receiving, from a first BS, a second TAG ID associated with a second BS and a PDCCH order; initiating a CFRA procedure in response to receiving the PDCCH order; transmitting, to a second BS, a RA preamble; receiving, for the second BS, a TAC included in a RAR or in a MAC CE; and applying the TAC and start a second time alignment timer corresponding to the second TAG ID associated with the second BS.
