Abstract
Techniques are described that provide network assisted multi-subscription physical layer sharing at a user equipment (UE) by transmitting a multi-subscription coordination capability to a network, establishing a link for a first subscription with the network based on the multi-subscription coordination capability, and establishing a second subscription with the network using the link based on the multi-subscription coordination capability, the first subscription is associated with the second subscription.
Claims29
A method for wireless communication at a user equipment (UE) with multi-subscription:
- transmitting a multi-subscription coordination capability to a network;
- establishing a link for a first subscription with the network based at least in part on the multi-subscription coordination capability;
- and
- establishing a second subscription with the network using the link based at least in part on the multi-subscription coordination capability, the first subscription being associated with the second subscription.
The method of claim 1, wherein the first subscription is associated with a first set of network slices and the second subscription is associated with a second set of network slices.
The method of claim 2, wherein the first set of network slices and the second set of network slices are different.
The method of claim 2, wherein the first set of network slices is associated with a first signaling connection and the second set of network slices is associated with a second signaling connection.
The method of claim 2, wherein the first set of network slices is associated with a first control network function (CNF) and a first access and mobility function (AMF), and the second set of network slices is associated with a second control network function (CNF) different from the first CNF and a second AMP different from the first AMP.
The method of claim 2, wherein the first set of network slices and the second set of network slices share a common UE radio frequency (RE) and physical link based at least in part on the multi-subscription coordination of the network and the UE.
10, The method of claim 1, further comprising:
- transmitting a radio resource control (RRC) message comprising a physical layer sharing capability as part of the multi-subscription coordination capability to the network.
The method of claim 10, further comprising:
- initiating an RRC connection setup phase for the second subscription;
- transmitting subscription association information between the first subscription and the second subscription to a serving cell of the first subscription based at least in part on a radio network temporary identifier (RNTI) list comprising at least an RNTI of the first subscription;
- and
- receiving an RRC connection reconfiguration message from the serving cell with physical layer sharing and at least one multi-subscription parameter.
12 The method of claim 11, wherein transmitting the subscription association information is via at least one of a new information element (IE) in an existing RRC message, or a connection setup complete message, or a new RRC message, or any combination thereof.
The method of claim 2, further comprising:
- determining the first subscription and the second subscription are in an RRC connected state with a same serving cell;
- and
- transmitting a subscription association indication to the same serving cell based at least in part on the determining.
The method of claim 19, further comprising:
- reporting subscription association information of multiple subscriptions associated with the multiple radios of the UE to the network, each radio of the multiple radios is associated with at least one subscription.
A method for wireless communication, comprising:
- receiving a physical layer sharing capability indication from a user equipment (UE);
- and
- receiving a multi-subscription coordination capability from the UE.
An apparatus for wireless communication, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- the processor and memory configured to:
- transmit a multi-subscription coordination capability to a network;
- establish a link for a first subscription with the network based at least in part on the multi-subscription coordination capability;
- and
- establish a second subscription with the network using the link based at least in part on the multi-subscription coordination capability, the first subscription is associated with the second subscription.
An apparatus for wireless communication, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- the processor and memory configured to:
- receive a physical layer sharing capability indication from a user equipment (UE);
- and
- receive a multi-subscription coordination capability from the UE.
