In an example, a user equipment (ue) operable to dynamically alter hybrid automatic retransmission re-quest (harq) mapping for carrier aggregation (ca) can include computer circuitry configured to: determine a secondary harq bundling window size for a secondary cell (scell), when a primary harq bundling window size for a primary cell (pcell) is zero; determine a physical uplink control channel (pucch) resource for transmission of a harq-acknowledge (ack) feedback using the secondary harq bundling window size; and transmit the harq-ack feedback in the pucch resource..
|Methods and apparatus for enabling further l1 enhancements in lte heterogeneous networks|
A network element in a first cell in a wireless telecommunication network is provided. The network element comprises a processor configured such that the network element provides uplink and downlink grants in the first cell, wherein the first cell is a low-power cell within the coverage area of a second, high-power cell, and wherein the first cell acts as a secondary cell and the second cell acts as a primary cell in a carrier aggregation mode, and wherein at least one uplink control signal is received by one of only the first cell or both the first cell and the second cell..
|Dynamic queuing and pinning to improve quality of service on uplinks in a virtualized environment|
At a network element having a plurality of physical links configured to communicate traffic over a network to or from the network element, an uplink group is formed comprising the plurality of physical links, wherein the plurality of physical links comprise a first physical link and a second physical link a plurality of classes of service are defined comprising a first class of service and a second class of service, wherein the first class of service and second class of service have bandwidth allocations on the first physical link. Traffic congestion is detected on the first physical link that exceeds a predetermined threshold for the first class of service.
