Paging over a high-speed downlink shared channel

A network entity configured for high speed downlink packet access (HSDPA) wireless communications with a wireless transmit/receive unit (WTRU), comprising

• a transmit/receive unit and a processor configured to:
• send, via a broadcast, system information indicating a delay between reception of a paging indicator and reception of a message;
• send HSDPA associated paging indicator channel (PICH) information elements comprising PICH information;
• send, during one or more paging occasions, the paging indicator over a PICH using the selected PICH information;
• and
• send the message on a high speed physical downlink shared channel (HS-PDSCH), wherein a maximum delay between the receptions of the paging indicator and the message is pre-determined.

A method implemented by a network entity to facilitate paging of a wireless transmit/receive unit (WTRU) for high speed downlink packet access (HSDPA) wireless communications, the method comprising:

• sending, via a broadcast, system information indicating a delay between reception of a paging indicator and reception using a high speed shared channel;
• sending, from a base station, HSDPA associated paging indicator channel (PICH) information elements comprising PICH information;
• sending, during paging occasions, the paging indicator over a PICH;
• sending a high speed downlink shared channel (HS-DSCH) radio network transaction identity (H-RNTI);
• and
• sending the high speed shared channel, wherein a maximum delay between the reception of the paging indicator and the reception using the high speed shared channel is pre-determined.
