Sidelink logical channel and resource configurations
Method, apparatus and systems are described to allow a base station to configure a logical channel or resources for sidelink communications. In one example aspect, a method for wireless communication includes receiving, by a user equipment, a message from a communication node. The message includes information for configuring a logical channel for a sidelink transmission. The method also includes configuring, a Medium Access Control (MAC) entity with the logical channel according to the information.
1. A method for wireless communication, comprising:
receiving, by a user equipment, a message from a communication node, wherein the message includes an SL-LogicalChannelConfig information element specifying information for configuring a sidelink logical channel for a sidelink transmission, wherein the information includes a scheduling request identity associated with the sidelink logical channel and one or more allowed configured grants associated with the sidelink logical channel, and wherein a presence of the scheduling request identity indicates that a corresponding scheduling request configuration is applicable to the sidelink logical channel;
configuring, by the user equipment, a Medium Access Control (MAC) entity of the sidelink logical channel according to the information; and
performing the sidelink transmission using the sidelink logical channel based on the configuring.
2. The method of claim 1 , wherein the information includes a priority associated with the sidelink logical channel.
3. The method of claim 1 , wherein the information indicates a logical channel group to which the sidelink logical channel belongs to.
4. The method of claim 1 , wherein the information indicates an allowed configured grant type.
5. The method of claim 1 , wherein the information includes one or more parameters related to Quality of Service (QOS) information associated with the sidelink logical channel.
6. A method for wireless communication, comprising:
transmitting, by a communication node, a message to a user equipment,
wherein the message includes an SL-LogicalChannelConfig information element specifying information that enables the user equipment to configure a MAC entity of a sidelink logical channel for a sidelink transmission,
wherein the information includes a scheduling request identity associated with the sidelink logical channel and one or more allowed configured grants associated with the sidelink logical channel, and wherein a presence of the scheduling request identity indicates that a corresponding scheduling request configuration is applicable to the sidelink logical channel.
7. The method of claim 6 , wherein the information includes a priority associated with the sidelink logical channel.
8. The method of claim 6 , wherein the information indicates a logical channel group to which the sidelink logical channel belongs to.
9. The method of claim 6 , wherein the information includes an allowed configured grant type.
10. The method of claim 6 , wherein the information includes one or more parameters related to Quality of Service (QOS) information associated with the sidelink logical channel.
11. A wireless communication apparatus, comprising a processor configured to:
receive a message from a communication node, wherein the message includes an SL-LogicalChannelConfig information element specifying information for configuring a sidelink logical channel for a sidelink transmission, wherein the information includes a scheduling request identity associated with the sidelink logical channel and one or more allowed configured grants associated with the sidelink logical channel, and wherein a presence of the scheduling request identity indicates that a corresponding scheduling request configuration is applicable to the sidelink logical channel;
configure a Medium Access Control (MAC) entity of the sidelink logical channel according to the information; and
perform the sidelink transmission using the sidelink logical channel based on the configuring.
12. The apparatus of claim 11 , wherein the information includes a priority associated with the sidelink logical channel.
13. The apparatus of claim 11 , wherein the information indicates a logical channel group to which the sidelink logical channel belongs to.
14. The apparatus of claim 11 , wherein the information includes an allowed configured grant type.
15. The apparatus of claim 11 , wherein the information includes one or more parameters related to Quality of Service (QOS) associated with the sidelink logical channel.
16. A wireless communication apparatus, comprising a processor configured to:
transmit a message to a user equipment,
wherein the message includes an SL-LogicalChannelConfig information element specifying information that enables a user equipment to configure a MAC entity of a sidelink logical channel for a sidelink transmission,
wherein the information includes a scheduling request identity associated with the sidelink logical channel and one or more allowed configured grants associated with the sidelink logical channel, and wherein a presence of the scheduling request identity indicates that a corresponding scheduling request configuration is applicable to the sidelink logical channel.
17. The apparatus of claim 16 , wherein the information includes a priority associated with the sidelink logical channel.
18. The apparatus of claim 16 , wherein the information indicates a logical channel group to which the sidelink logical channel belongs to.
19. The apparatus of claim 16 , wherein the information includes an allowed configured grant type.
20. The apparatus of claim 16 , wherein the information includes one or more parameters related to Quality of Service (QOS) information associated with the sidelink logical channel.
