Recently I have come across some information that DC-HSDPA has some limitations practically in Code Assignment for a Dual Cell User.

Earlier I had heard about 25.317 but didnt find it on server. Once I have more Info, I will blog about it.<br /><br />Regards,<br />ZahidZahid Ghadialyhttps://www.blogger.com/profile/11618208626682295272noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-58348064791612001972010-02-01T12:28:27.390+00:002010-02-01T12:28:27.390+00:00Hi Zahid,

Does it not become an overhead in such a case?Unknownhttps://www.blogger.com/profile/14935641536115262593noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-49532257462470159282009-12-09T10:32:43.695+00:002009-12-09T10:32:43.695+00:00For DC-HSPA different.

While using MIMO or DC HSDPA, does the network send same or different data packets over the 2 links?Unknownhttps://www.blogger.com/profile/14935641536115262593noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-62959827853412387022009-09-01T15:33:36.855+01:002009-09-01T15:33:36.855+01:00I dont think HSPA can meet the IMT-Advanced requir...I dont think HSPA can meet the IMT-Advanced requirements. There is a maximum rate (not sure how much) that HSPA can go to and its falls far behind the requirements.<br /><br />I also think that there will ultimately a limitation because of WCDMA as its not very efficient over very wide bandwidths.Zahid Ghadialyhttps://www.blogger.com/profile/11618208626682295272noreply@blogger.comtag:blogger.com,1999:blog-1834236085756782640.post-9425234876470687292009-09-01T15:20:29.739+01:002009-09-01T15:20:29.739+01:00Will HSPA be able to be proposed to IMT Advanced a...Will HSPA be able to be proposed to IMT Advanced as a 4G technology?
