What does Hsdpa mean on my phone?
HSDPA (High-Speed Downlink Packet Access) is a packet-based mobile telephony protocol used in 3G UMTS radio networks to increase data capacity and speed up transfer rates.
What type of information is carried over the HS Pdsch?
The HS-SCCH channel carries three main elements of information: It carries the UE identity to allow specific addressing of individual UEs on the shared control channel. The HS-SCCH carries the Hybrid ARQ to enable the combining process to proceed. This channel carries the Transport Format and Resource Indicator (TFRI).
Is Hsdpa the same as UMTS?
UMTS is a 3G telecommunications technology that makes use of the W-CDMA, as well as other permutations therein; HSDPA is part of the 3G network, but is part of the High Speed Packet Access family, therefore capable of elevated performance.
What type of information is transmitted by means of the HS-SCCH physical channel?
7 Downlink control signaling: HS-SCCH. The HS-SCCH, sometimes referred to as the shared control channel, is a shared downlink physical channel that carries control signaling information needed for a UE to be able to properly despread, demodulate, and decode the HS-DSCH.
What are the types of control channel?
According to the 3GPP standards [14], the logical channel types are: Broadcast Control Channel (BCCH), Paging Control Channel (PCCH), Common Control Channel (CCCH), Dedicated Control Channel (DCCH), Multi-cast Control Channel (MCCH), Dedicated Traffic Channel (DTCH), and Multicast Traffic Channel (MTCH).
How many control channels are there?
The group of Broadcast Channel is subdivided into three channels: Broadcast Control Channel (BCCH) Frequency Correction Channel (FCCH) Synchronization Channel (SCH)
Which is part of HSDPA does HS-pdsch use?
This is defined in Release 5 of the UMTS specifications. An HS-PDSCH may use QPSK or 16QAM modulation symbols. HS-PDSCH is also part of the HSDPA. HS-PDSCH is a downlink physical channel that carries user data and layer 2 overhead bits mapped from the transport channel: HS-DSCH.
Why do we need new channels for HSDPA?
To achieve the high speed data HSDPA uses new channels including: HS-DSCH, HS-SCCH, HS-DPCCH. HSDPA enables much higher speed data transfer and one reason it can achieve it is because of new channels that have been added.
What is HS-pdsch and how high speed physical?
HS-PDSCH High-Speed Physical Downlink Shared Channel is a channel added to UMTS to increase downlink data rates. This is defined in Release 5 of the UMTS specifications. An HS-PDSCH may use QPSK or 16QAM modulation symbols. HS-PDSCH is also part of the HSDPA.
Which is the shared channel in HSDPA NodeB?
High Speed Downlink Shared Channel, HS-DSCH. Th HS DSCH channel is the data transport channel that all active HSDPA users connected to the NodeB will use. The use of a shared channel is a key characteristic of HSDPA and being a common resource, the HS-DSCH is dynamically shared between users.
