20080232284 | Apparatus, method and computer program product providing semi-dynamic persistent allocation - A network element sets up a connection with an individual user equipment UE, provides an indicator that informs that a particular resource allocation to the individual user equipment is persistent, and sends resource allocations to a plurality of user equipments that includes the particular resource allocation to the individual user equipment. The indication can be implicit in the position of the particular resource allocation within the plurality of resource allocations as arranged during the connection setup, or it may be explicit with the resource allocation such as from a bit stolen from the CRC field. The persistent allocation can be terminated in multiple ways, including overwriting with a new persistent allocation, sending an end bit or no data, or sending an improper CRC field which is arranged by an absence of both a NACK from the UE and a re-transmission from the network as a terminating condition. | 09-25-2008 |
20090103500 | Re-transmission capability in semi-persistent transmission - One or more hybrid automatic repeat request process identifications are configured for scheduling without associated control signaling. A particular HARQ process ID to be assumed for a given subframe is determined based on at least one of: a) system frame number; b) number of hybrid automatic repeat request processes that are allocated for semi-persistent scheduling; and c) periodicity for semi-persistent scheduling. In various embodiments: a) is broadcast and b) and c) are sent via RRC signaling; and the assumed particular HARQ process ID is determined as a function of [Current TTI/SP_Period] mod Num_SP_HARQ:wherein Current TTI is a number for the given subframe derived from the system frame number and the term [Current TTI/SP_Period] is rounded to an integer prior to the modulo operation; SP_Period is the periodicity of the semi-persistent scheduling; and Num_SP_HARQ is the number of hybrid automatic repeat request processes that are allocated for semi-persistent scheduling. | 04-23-2009 |
