Problems solved by technology

However, since the DRNC has no knowledge of the capabilities of the WTRU at all, the DRNC of Release 7 does not know which channel the WTRU is monitoring for paging messages

Embodiment

[0140] CLAIMS 1. A method of paging a WTRU in CELL_PCH and URA_PCH states.

[0141] 2. The method of embodiment 1, comprising the WTRU sending an indication to indicate enhanced PCH capability for receiving HS-DSCH in CELL_PCH and URA_PCH states.

[0142] 3. The method of embodiment 2, further comprising the WTRU sending a second indication indicating enhanced FACH capability for receiving HS-DSCH in CELL_FACH state.

[0143] 4. The method of any one of embodiments 2-3, wherein the indication is included in one of a Cell Update message, a URA Update message, and a UTRAN Mobility Information Confirmation message.

[0144] 5. The method of embodiment 4, wherein if the capabilities of the new cell are different from those of the old cell, then sending the cell update message and the URA update message including the indication.

[0145] 6. The method according to any one of embodiments 4-5, wherein the URA update message including the indication is sent if the new cell supporting...

Abstract

A method and apparatus for paging a wireless transmit / receive unit (WTRU) in a CELL_PCH and URA_PCH states are disclosed. A WTRU may send an indication of an enhanced paging channel (PCH) capability of receiving a high speed downlink shared channel (HS-DSCH) in CELL_PCH and URA_PCH states, for example, in a CELL UPDATE message, a URA UPDATE message, or a UTRAN MOBILITY INFORMATION CONFIRM message. A drift radio network controller (DRNC) may receive an indication whether the WTRU has an enhanced PCH capability from a serving RNC and page the WTRU based on the indication. An RNC may page the WTRU over both an HS-DSCH and a PCH / secondary common control physical channel (S-CCPCH) if a WTRU capability is not known. The WTRU may monitor both an HS-DSCH and a PCH / S-CCPCH. The WTRU may configure reception over an HS-DSCH based on the capability of the SRNC or configuration from the network.

Description

technical field [0001] This application relates to wireless communications. Background technique [0002] Four Radio Resource Control (RRC) states are defined in conventional 3rd Generation Partnership Project (3GPP) specifications. These RRC states are CELL_DCH state, CELL_FACH state, CELL_PCH state and URA_PCH state. Improvements to the legacy CELL_FACH and CELL / URA_PCH states have been added in the 3GPP specifications to improve the overall quality of experience (QoE) experienced by end users. CELL_FACH and CELL_URA_PCH improvements reduce state transition delays, as well as overall signaling latencies, by using High Speed ​​Downlink Packet Access Resource (HSDPA) attempts in CELL_FACH and CELL / URA_PCH states. [0003] After introducing the enhanced CELL_FACH state, the High Speed ​​Downlink Shared Channel (HS-DSCH) can be used in the CELL_FACH state. HS-DSCH replaces the traditional Forward Access Channel (FACH). A wireless transmit / receive unit (WTRU) with enhanced ...
