Abstract
A persistent scheduling method and apparatus based on semi-grouping and statistically multiplexing, wherein a predetermined number of user equipments are grouped into a user equipment group to share allowable maximum transmission times of retransmission processes in different time slots each having a predetermined size, according to a predetermined set of criteria on communication conditions; and each user equipment within one user equipment group is allocated to use a corresponding time slot in a time division multiplexing mode.
Claims10
A persistent scheduling method based on user equipment semi-grouping and statistically multiplexing, comprising steps of:
- grouping a predetermined number of user equipments into a user equipment group to share allowable maximum transmission times of retransmission processes in different time slots each having a predetermined size, said grouping occurring according to a predetermined set of criteria on communication conditions such that each of the user equipments grouped together meet the same criteria;
- removing at least one user equipment from the user equipment group if an average packet error ratio of the user equipments in the user equipment group during a predefined measurement period is larger than a first threshold;
- and
- allocating each user equipment within the user equipment group to use a corresponding time slot in a time division multiplexing mode.
A persistent scheduling apparatus based on user equipment semi-grouping and statistically multiplexing, comprising:
- a grouper that groups a predetermined number of user equipments into a user equipment group to share allowable maximum transmission times of retransmission processes in different time slots each having a predetermined size, said grouping occurring according to a predetermined set of criteria on communication conditions such that each of the user equipments grouped together meet the same of criteria;
- an adjustor that removes at least one user equipment from the user equipment group if an average packet error ratio of the user equipments in the user equipment group during a predefined measurement period is larger than a first threshold;
- and
- an allocator that allocates each user equipment within the user equipment group to use a corresponding time slot in a time division multiplexing mode.
