NOTE 4: In 1.28 Mcps TDD, the list of available SYNC_UL codes (defined in PRACH info) is numbered from
SYNC_UL code index 0 to SYNC_UL code index N-1, where N is the number of available SYNC_UL
codes, starting with the lowest available SYNC_UL code number and continuing in sequence, in the order
of increasing SYNC_UL code numbers
The i-th bit of the bitmap defined in the IE "Available SYNC_UL codes indices" defines whether the
SYNC_UL code with the available SYNC_UL code index i is to be used for this ASC (bit set means
used, bit unset means not used). Only the low N bits shall be used in the bitmap, where N is the number
of available SYNC_UL codes defined in PRACH info.
- List of available SYNC_UL codes: 8 or fewer SYNC_UL codes are available.
Example: only signatures 0, 5, 6 and 7 are available, then:
- SYNC_UL codes 0 is: available SYNC_UL codes index 0
- SYNC_UL codes 5 is: available SYNC_UL codes index 1
- SYNC_UL codes 6 is: available SYNC_UL codes index 2
- SYNC_UL codes 7 is: available SYNC_UL codes index 3
Available SYNC_UL codes indices has the value '00001100' means: SYNC_UL codes 6 and 7 are
available for this ASC.
8.6.6.30 SRB delay, PC preamble (FDD only)
When the IE "SRB delay" and IE "PC preamble" is received in a message that results in a configuration of uplink
DPCH or E-DPCH, and synchronisation procedure A is being used as specified in [29], the UE shall:
1> store the received IE "SRB delay" and IE "PC preamble" in the variable
LATEST_CONFIGURED_SRB_DELAY_AND_PC_PREAMBLE;
1> apply power control preamble according to [26] during the number of frames indicated in the IE "PC preamble";
and
1> then not send any data on signalling radio bearers RB0 to RB4 during the number of frames indicated in the IE
"SRB delay" or while the physical channel is not considered established.
8.6.6.31 Void
8.6.6.32 Void
8.6.6.33 HS-SCCH Info
If the IE "HS-SCCH Info" is included and the UE will be in CELL_DCH state after completion of this procedure, the
UE shall:
1> store the received configuration.
1> determine the value for the HS_DSCH_RECEPTION variable and take the corresponding actions as described in
subclause 8.5.25.
When the variable HS_DSCH_RECEPTION is set to TRUE the UE shall:
1> in the case of FDD:
2> receive the HS-SCCH(s) according to the IE "HS-SCCH channelisation code" on the serving HS-DSCH
radio link applying the scrambling code as received in the IE "DL Scrambling code".
1> in the case of TDD:
