摘要:
In multi flow high speed downlink packed access, MF HSDPA, communication between a radio network controller, RNC, (105) and two Node Bs (104), redundant RLC PDUs are handled by being discarded in the Node B. The discarding can be controlled via a timer in the Node B or by way of additional signalling between the RNC and the Node B.

The present invention relates to a method of supporting a Hybrid Automatic Repeat and reQuest (HARQ) scheme of a reception end for supporting a dynamic resource change in a wireless communication system. In particular the method includes the steps of: receiving a change message for changing a currently applied first sub-frame setting to a second sub-frame setting from a transmission end; and transmitting and receiving a signal to and from the transmission end according to the second sub-frame setting, wherein a plurality of sub-frame settings including the first and second sub-frame settings are divided into one or more groups, the first and second sub-frame settings belong to an identical group, and the HARQ scheme is applied according to the group-specified maximum number of HARQ processes and a soft buffer size for each HARQ process when the sub-frame setting is changed according to the change message.

摘要:
The present subject matter discloses systems and methods for data transmission in communication networks. In one implementation, the method comprises determining a skew time based in part on a maximum skew time of the communication network and a probability of a data packet being delayed during transmission over the communication network. The method further includes detecting at least one missing data packet transmission and initiating retransmission of the at least one missing data packet after a time interval exceeding the determined skew time.
