Support of HS-DSCH DRX operation

OP

Enumerated (TRUE)

The absence of this IE indicates that the UE does not support HS-DSCH DRX operation in CELL_FACH state.

REL-8

Support of MAC-i/is

OP

Enumerated (TRUE)

The absence of this IE indicates that the UE does not support MAC-i/is operation.

REL-8

Support of SPS operation

OP

Enumerated (TRUE)

The absence of this IE indicates that the UE does not support SPS operation.

REL-8

OP

Enumerated (TRUE)

The absence of this IE indicates that the UE does not support control channel DRX operation.

REL-8

UE Mobility State Indicator

MD

Enumerated (High-mobilityDetected)

Absence of this IE implies that, according to [4] either the High mobility state is not applicable or it has not been detected by the UE.

REL-7

NOTE 1: For 1.28 Mcps TDD, UE supporting HS-PDSCH in CELL_FACH always supports E-DCH enhanced random access in CELL_FACH state and Idle mode, and vice versa. And UE supporting HS-PDSCH reception in CELL_FACH state always supports HS-DSCH reception in CELL_PCH and URA_PCH state and CELL_FACH HS-DSCH DRX operation.

Condition

Explanation

Failure

This IE is mandatory present if the IE "Failure cause" is present and not needed otherwise.

ConversationalCS

This IE is mandatory present if the IE "Establishment cause" has the value "Originating Conversational Call" or "Emergency Call" and a CS call is being initiated. Otherwise it is not needed.
