Definitions
- the basis for uplink (UL) and downlink (DL) scheduling is dynamic scheduling.
- scheduling information is transmitted during transmission timing intervals (TTIs) to a wireless transmit/receive unit (WTRU) via a physical downlink control channel (PDCCH).
- TTIs transmission timing intervals
- PDCCH physical downlink control channel
- RAN radio access network
- RAN2 radio access network
- RAN2 radio access network
- a solution includes both the WTRU and the eNB to assume that the next available HARQ process-ID is used for a persistently scheduled DL transmission. However, this procedure would not be robust enough in the presence of errors.
- WTRU 105 reserves the HARQ process for UL dynamic transmission, X number of TTIs, for example one (1), before the start of the next SFN to use the same reserved HARQ process t for UL persistent transmission, the WTRU 105 flushes the buffer 140 with the unfinished UL dynamic transmission associated with HARQ process t to prepare for the next UL persistent transmission.
- Suitable processors include, by way of example, a general purpose processor, a special purpose processor, a conventional processor, a digital signal processor (DSP), a plurality of microprocessors, one or more microprocessors in association with a DSP core, a controller, a microcontroller, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) circuits, any other type of integrated circuit (IC), and/or a state machine.
- DSP digital signal processor
- ASICs Application Specific Integrated Circuits
- FPGAs Field Programmable Gate Arrays
