Abstract
The setting of a value of the transmission control parameter for a transmission of data on a multi-hop relay radio link of a cellular network is controlled. Said controlling is based on a route time of a packet transmitted between end nodes of the multi-hop relay radio link. E.g., the transmission control parameter may relate to a property of an Automatic Repeat Request protocol.
Claims16
A device, comprising:
- at least one processor configured to control setting of a value of a transmission control parameter for a transmission of data on a multi-hop relay radio link of a cellular network, said controlling being based on a route time of a packet transmitted between end nodes of the multi-hop relay radio link,
- wherein the multi-hop relay radio link comprises a plurality of links between neighboring nodes and extends between the respective end nodes of the multi-hop relay radio link,
- wherein the transmission control parameter relates to a property of an Automatic Repeat Request protocol employed by the end nodes to protect the transmission of the data on the multi-hop relay radio link,
- wherein the property of the Automatic Repeat Request protocol is selected from a group comprising:
- a size of a transmission window and a size of a sequence number space, and wherein same values for the size of the sequence number space and the size of the transmission window, are reused for the nodes of the multi-hop relay radio link.
A method, comprising:
- controlling a setting of a value of a transmission control parameter for a transmission of data on a multi-hop relay radio link of a cellular network based on a route time of a packet transmitted between end nodes of the multi-hop relay radio link,
- wherein the multi-hop relay radio link comprises a plurality of links between neighboring nodes and extends between the respective end nodes of the multi-hop relay radio link,
- wherein the transmission control parameter relates to a property of an Automatic Repeat Request protocol employed by the end nodes to protect the transmission of the data on the multi-hop relay radio link,
- wherein the property of the Automatic Repeat Request protocol is selected from a group comprising:
- a size of a transmission window and a size of a sequence number space, and wherein same values for the size of the sequence number space and the size of the transmission window, are reused for the nodes of the multi-hop relay radio link.
A computer program product comprising a non-transitory computer readable medium comprising program code, wherein execution of the program code by at least one processor causes the at least one processor to execute a method comprising:
- controlling a setting of a value of a transmission control parameter for a transmission of data on a multi-hop relay radio link of a cellular network based on a route time of a packet transmitted between end nodes of the multi-hop relay radio link,
- wherein the multi-hop relay radio link comprises a plurality of links between neighboring nodes and extends between the respective end nodes of the multi-hop relay radio link,
- wherein the transmission control parameter relates to a property of an Automatic Repeat Request protocol employed by the end nodes to protect the transmission of the data on the multi-hop relay radio link,
- wherein the property of the Automatic Repeat Request protocol is selected from a group comprising:
- a size of a transmission window and a size of a sequence number space, and wherein same values for the size of the sequence number space and the size of the transmission window, are reused for the nodes of the multi-hop relay radio link.
