Method for reducing serving cell interruption due to prose operation
A method in a network node ( 115 ) is disclosed. The method comprises determining ( 504 ) whether a wireless device ( 110 ) is configured with discontinuous reception on a first communication link. The method comprises comparing ( 508 ) a target quality for a second communication link with an interruption probability or rate due to operation of the first communication link, and selecting ( 512 ) a scheduling scheme based at least in part on the comparison of the target quality for the second communication link with the interruption probability or rate due to operation of the first communication link. The method comprises scheduling ( 516 ) one or more resources for the wireless device ( 110 ) according to the selected scheduling scheme.
1. A method in a wireless device, comprising:
determining a maximum interruption rate due to operation of a first communication link for ProSe communication;
determining a target quality for a second communication link for wide area network (WAN) communication;
comparing the target quality for the second communication link for WAN communication with the maximum interruption rate for the first communication link for ProSe communication to determine whether the target quality for the second communication link for WAN communication is lower than the maximum interruption rate due to operation of the first communication link for ProSe communication;
determining whether or not to turn off a receiver chain for the first communication link for ProSe communication based at least in part on whether the target quality for the second communication link for WAN communication is lower than the maximum interruption rate due to operation of the first communication link for ProSe communication, and
wherein upon determining that the target quality for the second communication link is lower than the maximum interruption rate, not turning off the receiver chain for the first communication link for ProSe communication.
2. The method of claim 1 , wherein upon determining that the target quality for the second communication link is not lower than the maximum interruption rate, turning off the receiver chain for the first communication link for ProSe communication.
3. The method of claim 1 , further comprising receiving, from a network node, information indicating whether the wireless device is allowed to turn off a receiver chain for the first communication link.
4. The method of claim 1 , further comprising sending, to a network node, information indicating a result of the comparison of the target quality for the second communication link with the maximum interruption rate.
5. The method of claim 1 , further comprising sending, to a network node, information about at least one of an actual quality for the second communication link and an actual interruption rate for the first communication link.
6. The method of claim 1 , wherein the target quality for the second communication link comprises one of a target block error ratio and a target frame error rate.
7. A wireless device, comprising:
one or more processors, the one or more processors configured to:
determine a maximum interruption rate due to operation of a first communication link for ProSe communication;
determine a target quality for a second communication link for wide area network (WAN) communication;
compare the target quality for the second communication link for WAN communication with the maximum interruption rate for the first communication link for ProSe communication to determine whether the target quality for the second communication link for WAN communication is lower than the maximum interruption rate due to operation of the first communication link for ProSe communication; and
determine whether or not to turn off a receiver chain for the first communication link for ProSe communication based at least in part on whether the target quality for the second communication link for WAN communication is lower than the maximum interruption rate due to operation of the first communication link for ProSe communication, and
wherein upon determining that the target quality for the second communication link is lower than the maximum interruption rate, not turning off the receiver chain for the first communication link for ProSe communication.
8. The wireless device of claim 7 , wherein upon determining that the target quality for the second communication link is not lower than the maximum interruption rate, the one or more processors are configured to turn off a receiver chain for the first communication link for the ProSe communication.
9. The wireless device of claim 7 , wherein the one or more processors are further configured to receive, from a network node, information indicating whether the wireless device is allowed to turn off a receiver chain for the first communication link.
