Techniques for traffic steering between access links and sidelinks in wireless communications systems

A method for wireless communication at a network device, comprising:

• transmitting, to a user equipment (UE), a logical channel configuration for a set of logical channels at the UE, the logical channel configuration indicating whether each logical channel of the set of logical channels is configured to use an access link, or a sidelink, or both,
• wherein the logical channel configuration indicates at least one logical channel of the set of logical channels that is configured to use a different type of link than another logical channel of the set of logical channels and a set of scheduling request configurations comprising at least a first scheduling request configuration for the access link and a second scheduling request configuration for the sidelink;
• and
• receiving a message including available data for a logical channel of the set of logical channels at the UE,
• wherein the message including the available data is received via the access link based at least in part on the logical channel configuration for the logical channel.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, via a receiver, a logical channel configuration for a set of logical channels at the UE, the logical channel configuration indicating whether each logical channel of the set of logical channels is configured to use an access link, or a sidelink, or both,
• wherein the logical channel configuration indicates at least one logical channel of the set of logical channels that is configured to use a different type of link than another logical channel of the set of logical channels and a set of scheduling request configurations comprising at least a first scheduling request configuration for the access link and a second scheduling request configuration for the sidelink;
• and
• transmit, via a transmitter, a message including available data based at least in part on a logical channel of the set of logical channels having the available data,
• wherein the message including the available data is transmitted on the access link or the sidelink based at least in part on the logical channel configuration for the logical channel.

An apparatus for wireless communication at a network device, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, via a transmitter and to a user equipment (UE), a logical channel configuration for a set of logical channels at the UE, the logical channel configuration indicating whether each logical channel of the set of logical channels is configured to use an access link, or a sidelink, or both,
• wherein the logical channel configuration indicates at least one logical channel of the set of logical channels that is configured to use a different type of link than another logical channel of the set of logical channels and a set of scheduling request configurations comprising at least a first scheduling request configuration for the access link and a second scheduling request configuration for the sidelink;
• and
• receive, via a receiver, a message including available data for a logical channel of the set of logical channels at the UE,
• wherein the message including the available data is received via the access link based at least in part on the logical channel configuration for the logical channel.
