`Proposed Work Item on Optimisation of Channelisation Code
`Utilisation for TDD
`Document for: Approval
`
`
`Code utilisation is an important element for the uplink and downlink efficiency of UTRA-
`TDD cells. Several features require a UE specific code for a dedicated channel, such as
`HSDPA which requires an associated DPCH, IMS with infrequent RTCP packets and full
`headers which have to be sent with low delay.
`
`HSDPA transmissions also require channelisation codes and so efficient code utilisation of
`dedicated channels also improves HSDPA performance.
`
`For TDD code resources are limited on both uplink and downlink. Efficient utilisation and
`careful management of both downlink and uplink code resources is desirable.
`
`The proposed work item follows.
