A method and a wireless transmit/receive unit, WTRU, to facilitate paging in high speed downlink packet access, HSDPA, wireless communications, the method comprising: when the WTRU is in one of a CELL PCH and URA PCH state: receiving, from a base station, HSDPA associated paging indicator channel, PICH, information elements comprising PICH information; compiling a list of candidate PICHs for HSDPA after receiving the information element; determining a value k corresponding to a number of candidates; calculating a selection index equal to:U_RNTI mod k, where U RNTI is a universal mobile telecommunications system (UMTS) terrestrial radio access network (UTRAN) radio network transaction identity (U-RNTI) of the WTRU; selecting a PICH information from the list of candidate PICHs based on the selection index; awakening from a sleep mode during paging occasions derived from the PICH information; monitoring for a paging indicator over a PICH using the selected PICH information; monitoring for a high speed dedicated shared channel, HS-DSCH, radio network transaction identity, H-RNTI; monitoring a high speed shared channel using the received H-RNTI; and returning to the sleep mode, if no H-RNTI is received. |
