Method and apparatus for handling cell reselections and transitions to and from an enhanced cell
A method and apparatus for handling cell reselections and transitions includes executing a cell reselection. A medium access control (MAC)-ehs reset is performed.
1. A method implemented by a network entity (NE) for handling cell reselections, the method comprising:
generating, by the NE, a message that includes high speed downlink shared channel (HS-DSCH) common system information in System Information Block (SIB) 5 or SIB 5 bis;
broadcasting, by the NE to a Wireless Transmit/Receive Unit (WTRU), the message such that a medium access control (MAC) reset is performed by a WTRU on condition that the broadcasted message is received by the WTRU and a variable HS_DSCH_RECEPTION_OF_CCCH_ENABLED is set to TRUE.
2. The method of claim 1 , further comprising:
sending a connection setup message having a value of an Initial UE identity information element (IE) equal to a value of a variable INITIAL_UE_IDENTITY on condition that a RRC CONNECTION REQUEST message having the Initial UE identity IE set to the value of the variable INITIAL_UE_IDENTITY is received.
3. The method of claim 1 , further comprising acting, by the NE, on a cell reselection of the WTRU to a cell of the NE.
4. The method of claim 1 , further comprising sending, by the NE, a Frequency info (FI) information element to enable the WTRU to select a cell on a frequency associated with the Fl IE.
5. The method of claim 1 , further comprising sending, by the NE, DRX cycle information to control the WTRU to monitor paging occasions on a selected paging information channel (PICH).
6. A network entity (NE) for handling cell reselections, comprising:
a receiver;
a transmitter; and
a processor in communication with the receiver and the transmitter,
wherein:
the processor is configured to generate a message that includes high speed downlink shared channel (HS-DSCH) common system information in System Information Block (SIB) 5 or SIB 5bis, and
the transmitter is configured to broadcast the message to a Wireless Transmit/Receive Unit (WTRU) such that a medium access control (MAC) reset is performed by a WTRU on condition that the broadcasted message is received by the WTRU and a variable HS_DSCH_RECEPTION_OF_CCCH_ENABLED is set to TRUE.
7. The NE of claim 6 , wherein the transmitter is configured to send a connection setup message having a value of an Initial UE identity information element (IE) equal to a value of a variable INITIAL_UE_IDENTITY on condition that a RRC CONNECTION REQUEST message is received having the Initial UE identity IE set to the value of the variable INITIAL_UE_IDENTITY.
8. The NE of claim 6 , wherein the processor is configured to act on a cell reselection of the WTRU to a cell of the NE.
9. The NE of claim 6 , wherein the transmitter is configured to send a Frequency info (FI) information element to enable the WTRU to select a cell on a frequency associated with the Fl IE.
10. The NE of claim 6 , wherein the transmitter is configured to send DRX cycle information to control the WTRU to monitor paging occasions on a selected paging information channel (PICH).
