Problems solved by technology

However, TAU performed at too frequent a period may result in large uplink signaling overhead
[0011] The second problem is ineffective paging due to large paging load
But single receiver WTRU will only operate on MBMS dedicated layer or hybrid cell
Thus, a duplicated paging message would result in a waste of radio resources in one of these layers

Embodiment

[0120] CLAIMS 1. A Wireless Transmit / Receive Unit (WTRU) configured to receive multimedia signals.

[0121] 2. The WTRU of embodiment 1 wherein the WTRU is further configured to receive multicast signals, unicast signals, or a hybrid signal comprising multicast and unicast signals.

[0122] 3. The WTRU as in any one of the preceding embodiments wherein the multimedia signal is a Multicast Broadcast Multimedia Signal (MBMS).

[0123] 4. The WTRU as in any one of the preceding embodiments, wherein the WTRU is further configured to switch between receiving the MBMS and receiving the hybrid signal.

[0124] 5. The WTRU as in any one of the preceding embodiments, wherein the WTRU is further configured to determine an optimal time to switch between receiving the MBMS signal and receiving the hybrid signal.

[0125] 6. The WTRU as in any one of the preceding embodiments, wherein the WTRU is further configured to switch between receiving the MBMS signal and the hybrid signal in an ad...

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...
