Abstract: A guard period for switching between uplink and downlink subframes is created by shortening a downlink subframe, i.e., by not transmitting during one or more symbol intervals at the end of the subframe. A grant message includes signaling indicating when a shortened subframe is being transmitted. An example method is implemented in a receiving node configured to receive data from a transmitting node in subframes having a predetermined number of symbol intervals. In an LTE system, this receiving node may be a UE, and the subframes are downlink subframes. This example method includes determining that a received subframe is to be shortened, relative to the predetermined number of symbol intervals and, in response to this determination, disregarding a last part of the received subframe by disregarding one or more symbols at the end of the received subframe when processing the received subframe.

Abstract: A first network node, a second network node and methods therein, for handling baseband processing of signals communicated with wireless devices in a wireless network. The first network node communicates a first type of signals with a first wireless device and performs a first part of baseband processing of the first type of signals using a non-GPP implemented processor. The first network node also communicates the first type of signals with the second network node for a second part of baseband processing of the first type of signals using a GPP implemented processor. The first network node further communicates a second type of signals with a second wireless device and performs both of said first and second parts of baseband processing of the second type of signals using the non-GPP implemented processor.

Abstract: Embodiments herein relate to a method performed by a radio node (13) for managing communication of one or more wireless devices (10) within a wireless communication network (1); which wireless communication network (1) comprises a radio access network node (12) serving the radio node (13). The radio node (13) receives an indication of radio resources out of a total spectrum of radio resources controlled by the radio access network node (12) for communication over a first radio interface using a first radio access technology, which indicated radio resources are allocated to the radio node (13) from the radio access network node (12) for communication over a second radio interface, which second radio interface uses a second radio access technology being different than the first radio access technology. The radio node (13) allocates at least part of the indicated radio resources for communication to and/or from the one or more wireless devices (10) over the second radio interface.
