Abstract

A WTRU configured to receive a multicast, a unicast or mixed signal. A multimedia signal may be a Multimedia Broadcast Multicast Signal (MBMS). The WTRU switches between an MBMS and a mixed signal anddetermines optimal time to switch between the MBMS and mixed signal. The WTRU switches between receiving the MBMS and mixed signal in an adaptive or semi-static pattern. A flat broadcast channel (BCH) structure in an MBMS dedicated cell is provided, eliminating need for a dedicated broadcast channel (D-BCH). An MBMS-dedicated cell uses a single paging channel for both paging-indicators and paging-record-blocks. A system information broadcast indicates flexible resource usage and paging-record-block limits. Tracking area (TA) / cell association is provided for an MBMS-dedicated cell and geographically co-located non-MBMS-dedicated cells. MBMS-dedicated cell system information is broadcast to regulate WTRU operation while receiving MBMS within said cell. Generic Access Profile (GAP) definitions is part of system information.

Description

technical field

[0001] The present invention relates to wireless communication systems. Background technique

[0002] The 3rd Generation Partnership Project (3GPP) has recently launched the LTE project to bring new technologies, new network architectures, new configurations, and new applications and services to wireless cellular networks, thereby providing improved spectral efficiency and more Fast user experience. Meanwhile, in order to continue to provide Multimedia Broadcast Multicast Service (MBMS) under LTE network and technology, 3GPP has defined some new concepts and architectures for MBMS.

[0003] The Evolved Universal Mobile Telecommunications System (UMTS) project and the UMTS Terrestrial Radio Access Network (UTRAN) project aim to develop an optimal packet radio access network with high data rate, low latency and improved system capacity and coverage. To achieve this goal, improvements to the radio interface as well as the radio network architecture should be c...
