Abstract
A method in a network node for multiplexing a physical channel between the network node and devices in a mixed wireless network, wherein the mixed wireless network comprises a cellular network comprising one or more cellular channels and a Device-to-Device (D2D) network comprising one or more D2D channels. The method includes time division multiplexing the physical channel between a first group of cellular channels and a first group of D2D channels, and frequency division multiplexing the physical channel between a second group of cellular channels and the first group of D2D channels.
Claims36
A method in a network node (110) for multiplexing a physical channel (400), between the network node (110) and devices (121, 122, 123) comprised in a mixed wireless network (100), wherein the mixed wireless network (100) further comprises a cellular network comprising one or more cellular channels and a Device-to-Device, D2D, network comprising one or more D2D channels, the method comprising:
- time division multiplexing (301) the physical channel (400) between a first group of cellular channels (411, 412) and a first group of D2D channels (431, 432);
- and
- frequency division multiplexing (302) the physical channel (400) between a second group of cellular channels (421) and the first group of D2D channels (431, 432).
A network node (110) for multiplexing a physical channel (400), between the network node (110) and devices (121, 122, 123) comprised in a mixed wireless network (100), wherein the mixed wireless network (100) further comprises a cellular network comprising one or more cellular channels and a Device-to-Device, D2D, network comprising one or more D2D channels, the network node (110) comprising:
- a multiplexing circuit (1601) configured to:
- a. time division multiplex the physical channel (400) between a first group of cellular channels (411, 412) and a first group of D2D channels (431, 432);
- and
- b. frequency division multiplex the physical channel (400) between a second group of cellular channels (421) and the first group of D2D channels (431, 432).
