Multi-Slot Capability

An MS is allocated with timeslots based on the priority of the request service type. The maximum number of timeslots that are allocated to an MS whose multislot class is 11 is as follows:

In the case of a service type that is of top or middle priority in the uplink, the number of allocated timeslots is 3 (downlink) + 2 (uplink) if the EDA is not supported; the number of the allocated timeslots is 2 (downlink) + 3 (uplink) or 1 (downlink) + 3 (uplink) if the EDA is supported.

In the case of the service type that is of top priority in the downlink, the number of the allocated timeslots is 4 (downlink) + 1 (uplink).
