Method for performing paging using downlink sharing physical channel

Abstract

The disclosed calling method using down share physical channel comprises: setting mark domain in the frame structure of down share control channel to label this channel as the calling indication channel or other control indication channel; when labeling this as the calling indication channel, the frame structure also contains the calling indication domain; UE monitors the lab el to decide whether the down share control channel as the calling indication channel; if yes, UE decides the relative calling indication effective, and user terminal receives the calling message from the calling channel mapped on the down share physical channel according to down share physical channel configuration message. This invention combines the calling indication channel into the down share control channel to simplify system, and increases the utility of wireless resource.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a paging method using a downlink shared physical channel. technical background [0002] In the 3GPP Universal Terrestrial Radio Access Network (3GPP UTRAN) communication standard, the network broadcast paging message is broadcast on the Paging Indicator Channel (PICH: Paging Indicator Channel) and transmitted through the Paging Channel (PCH: Paging Channel). The indicator channel (PICH) does not carry the data of the transport channel, but is used in pair with the PCH to indicate whether a specific UE needs to interpret the following PCH channel. PCH and PICH can be mapped to the second common control physical channel (S-CCPCH: Secondary Common Control Physical Channel) at the same time, and the basic common control physical channel (P-CCPCH: Primary Common Control Physical Channel) and S-CCPCH can also be simultaneously It is mapped to a physical time slot, and t...

Problems solved by technology

The PCH is periodically mapped to the S-CCPCH physical channel. When there is no paging information for the UE, or when there is little information about the paging UE, the resource configuration of the S-CCPCH remains unchanged, so that the utilization of radio resources Low rate, inflexible resource allocation

Before the 3GPP Long Term Evolution (LTE) plan was formulated, only the paging indication information was carried in the PICH, and the information about the mapping of the PCH to the physical channel was notified by the system to the UE. This is the same as the mapping from the transport channel to the shared physical channel in LTE. Inconsistent methods for channel indication lead to complex relationships between channels, which is not conducive to channel management
