METHOD AND SYSTEM FOR DECODING MBSFN DATA

摘要

A method of Physical Multicast Channel (PMCH) decoding for Multicast Broadcast Single Frequency Network (MBSFN) by a UE includes decoding a Transport Block (TB) in a first sub-frame of a Multicast Channel Scheduling Period (MSP) by a Physical (PHY) layer in the UE; providing the decoded TB to a Media Access Control (MAC) layer; performing blind decoding on all received MBSFN sub-frames, until the PHY layer receives PMCH scheduling configuration from the MAC layer; selecting at least one Logical Channel IDentifier (LCID) and Multicast Transport Channel (MTCH) scheduling information for each LCID by decoding a Multicast Channel Scheduling Information Protocol Data Unit (MSI PDU), the MSI PDU present in the decoded TB; building a PMCH scheduling configuration by the MAC layer based on the selected at least one LCID and the MTCH scheduling information; passing the PMCH scheduling configuration to the PHY layer by the MAC layer; and applying the PMCH scheduling configuration.

1. A method of Physical Multicast Channel (PMCH) decoding for Multicast Broadcast Single Frequency Network (MBSFN) by a User Equipment (UE) in a wireless communication network, the method comprising:
decoding a Transport Block (TB) in a first sub-frame of a Multicast Channel Scheduling Period (MSP) by a Physical (PHY) layer in the UE; providing the decoded TB to a Media Access Control (MAC) layer in the UE by the PHY layer; performing blind decoding on all received MBSFN sub-frames by the PHY layer, until the PHY layer receives PMCH scheduling configuration from the MAC layer; selecting at least one Logical Channel IDentifier (LCID) and Multicast Transport Channel (MTCH) scheduling information for each of the at least one LCID by the MAC layer by decoding a Multicast Channel Scheduling Information Protocol Data Unit (MSI PDU), wherein the MSI PDU is present in the decoded TB; building a PMCH scheduling configuration by the MAC layer based on the selected at least one LCID and the MTCH scheduling information; passing the PMCH scheduling configuration to the PHY layer by the MAC layer; and applying the PMCH scheduling configuration by the PHY layer.
