LATENCY REDUCTION FOR MODE SWITCHING IN SIDELINK COMMUNICATIONS
First Claim
1. A method in a wireless terminal which is capable of wireless communications with a node of a radio access network over a radio interface, the method comprising:
- providing a first set of radio resources 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;
providing a second set of radio resources which may be used by the wireless terminal when performing a device-to-device (D2D/SL) communication with the another wireless terminal when the wireless terminal is not within coverage of the radio access network;
allowing the wireless terminal, when still within coverage of the radio access network, to use the second set of resources for the device-to-device (D2D/SL) communication in conjunction with a random access procedure.

Abstract
A wireless terminal (26) is capable of wireless communications with a node (22) of a radio access network over a radio interface. 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.

2. A wireless terminal which is capable of communicating over a radio interface with a node of a radio access network, the wireless terminal comprising:
-
a processor configured to allocate a radio resource from a first set of radio resources 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 and to allocate a radio resource from a second set of radio resources which may be used by the wireless terminal when performing a device-to-device (D2D/SL) communication with the another wireless terminal when the wireless terminal is not within coverage of the radio access network; wherein the processor is configured to allow the wireless terminal, when still within coverage of the radio access network, to use the second set of resources for the device-to-device (D2D/SL) communication in conjunction with a random access procedure. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
