A method in the wireless terminal (26) comprises providing both a first set of radio resources (56) and a second set of radio resources (58). The first set of radio resources (56) is which may be used by the wireless terminal when performing a device-to-device (D2D/SL) communication with another wireless terminal when the wireless terminal is within coverage of a radio access network. The second set of radio resources (58) is which may be used by the wireless terminal when performing a device-to-device (D2D/SL) communication with the other wireless terminal when the wireless terminal is not within coverage of the radio access network. The method further comprises allowing the wireless terminal (26), when still within coverage of the radio access network, to use the second set of resources (58) for the device-to-device (D2D/SL) communication in conjunction with a random access procedure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Latency reduction for mode switching in sidelink communications","description":"A wireless terminal (26) is capable of wireless communications with a node (22) of a radio access network over a radio interface.
