Chase combining
retransmission scheme
The Chase combining retransmission scheme is the simplest
HARQ (Hybrid Automatic Request) link adaptation technique.
HARQ techniques are used to enhance system performance.
HSDPA Compressed Mode
Allows the user equipment to interrupt transmission and
reception during a call for brief periods in order to measure the
signal strength of neighboring cells that use different
frequencies.
(SL8080/82/84)
Concurrent voice and HSDPA
data
HSDPA Indicator
Allows user interface to display an indicator when HSDPA data
transfer is in progress.
Receiver equalizer support
Miscellaneous
Fast link adaptation
The data rate is adapted to radio conditions.
Vary the effective code rate
The effective code rate is varied based on code space
resources.
HARQ, MAC-HS disassembly
MAC-HS (High Speed MAC) is the base station MAC (Medium
Access Control) protocol. MAC-HS enables fast radio resource
allocation.
MAC-HS reordering queue
distribution and processing
support
Cell change
These cell change methods are supported:
•
Synchronous and non-synchronous
•
Intra-Node B (softer repointing)
•
Inter-Node B (soft repointing)
Up-switching and down-
switching of PS RAB between
HS-PDSCH and DPCH
RAB (Radio Access Bearer) and channel mappings between the
HS-PDSCH (High Speed Physical Downlink Shared Channel)
and DPCH (Dedicated Physical Channel) are reallocated
according to volume thresholds and inactivity timers.
Ciphering on the HS channel
Ciphering on high-speed channels protects radio-transmitted
data against unauthorized third parties.
Support to not resume the HS
channel if inter-RAT handover
fails, but save the RB mapping
information
RB (Radio Bearer) mapping information is preserved if a high-
speed channel is dropped due to the failure of an inter-RAT
(Radio Access Technology) transfer.
Support to not resume the HS
channel if a radio link failure
occurs, but save the RB
mapping information
RB (Radio Bearer) mapping information is preserved if a high-
speed channel is dropped due to a radio link failure.
WINS address support primary
and secondary
Primary and secondary IP addresses can be assigned for WINS
(Windows Internet Name Service) name servers.
(SL8080/82/84)
