Abstract
A wireless device (12A) receives a sidelink configuration from each of multiple network nodes (20A, 20B) serving the wireless device (12A). The wireless device (12A) selects, from the received sidelink configurations, a sidelink configuration (16A) that is consistent or compatible with a sidelink configuration (16B) of another wireless device (12B) with which the wireless device (12A) is to communicate over a sidelink. The wireless device (12A) in some embodiments transmits, to each of one or more of the network nodes (20A, 20B) serving the wireless device (12A), an indication of the selected sidelink configuration (16A).
Claims7
A method performed by a first wireless device, the method comprising:
- receiving a sidelink configuration from each of multiple network nodes serving the first wireless device;
- selecting, from the received sidelink configurations, a sidelink configuration that is consistent or compatible with a sidelink configuration of a second wireless device with which the first wireless device is to communicate over a sidelink, wherein the selected sidelink configuration is selected based on a determination that the selected sidelink configuration is consistent or compatible with the sidelink configuration of the second wireless device;
- and
- transmitting, to each of one or more of the network nodes serving the first wireless device, an indication of the selected sidelink configuration;
- wherein a sidelink configuration comprises a Radio Link Control (RLC) mode configuration comprising configuration of RLC unacknowledged mode or RLC acknowledged mode;
- wherein said selecting comprises selecting, from the received sidelink configurations, a sidelink configuration that comprises the same RLC mode configuration as an RLC mode configuration of the sidelink configuration of the second wireless device with which the first wireless device is to communicate over the sidelink, wherein the selected sidelink configuration is selected based on the selected sidelink configuration comprising the same RLC mode configuration as the RLC mode configuration of the sidelink configuration of the second wireless device with which the first wireless device is to communicate over the sidelink.
A first wireless device comprising:
- communication circuitry;
- and
- processing circuitry configured to:
- receive a sidelink configuration from each of multiple network nodes serving the first wireless device;
- and
- select, from the received sidelink configurations, a sidelink configuration that is consistent or compatible with a sidelink configuration of a second wireless device with which the first wireless device is to communicate over a sidelink, wherein the selected sidelink configuration is selected based on a determination that the selected sidelink configuration is consistent or compatible with the sidelink configuration of the second wireless device;
- and
- transmit, to each of one or more of the network nodes serving the first wireless device, an indication of the selected sidelink configuration;
- wherein a sidelink configuration comprises a Radio Link Control (RLC) mode configuration comprising configuration of RLC unacknowledged mode or RLC acknowledged mode;
- wherein the processing circuitry is configured to select, from the received sidelink configurations, a sidelink configuration that comprises the same RLC mode configuration as an RLC mode configuration of the sidelink configuration of the second wireless device with which the first wireless device is to communicate over the sidelink, wherein the selected sidelink configuration is selected based on the selected sidelink configuration comprising the same RLC mode configuration as the RLC mode configuration of the sidelink configuration of the second wireless device with which the first wireless device is to communicate over the sidelink.
