Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus of a wireless signal supporting cross-carrier scheduling.

Background

In an LTE (Long-Term Evolution) system, one UE (User Equipment) is served by multiple Serving cells (Serving cells) at the same time. Wherein one of the serving cells serves as a PCell (Primary Cell) of the UE, and is configured to transmit system information and complete random access; the other cells are used for data transmission as scells (Secondary cells). When a UE (User Equipment) needs to change a PCell, the UE needs to trigger an inter-cell HO (Handover) or cell reselection process.

In the 3rd generation partner Project (3 GPP) new air interface discussion, due to the introduction of Beamforming (Beamforming), the distribution among cells, i.e. the inter-cell interference situation, is more complicated, and in consideration of the delay caused by inter-cell HO or cell reselection, a new, faster and more efficient method for serving cell selection and handover, especially for PCell, needs to be designed.

Disclosure of Invention

The inventor finds, through research, that in the current system, when a UE switches a PCell, an HO or cell reselection procedure is triggered, and both the HO or cell reselection procedure and the HO or cell reselection procedure trigger upper layer reconfiguration such as MAC (Medium/Media Access Control), RRC (Radio Resource Control), PDCP (Packet Data Convergence Protocol), and the like, so that efficiency of the PCell switching procedure is low and delay is large.
