Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from abase station, an indicator of a data split between a New Radio (NR) channel and a legacy channel. Accordingly, the UE may transmit, to the base station, an indicator of a modification of the data split based at least in part on a ratio of an amount of data flowing over the NR channel to a total amount of data flowing over the NR channel and the legacy channel. Additionally, or alternatively, the UE may transmit, to the base station, an indicator of a modification of the data split based at least in part on an indicator of a quality of the legacy channel. Numerous other aspects are provided.

First claim

What is claimed is:

1 . An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more memories and the one or more processors configured to:
receive, from a network node, an indicator of a data split between a New Radio (NR) channel and a legacy channel;
transmit, to the network node, an indicator of a modification of the data split based at least in part on a ratio of an amount of data flowing over the NR channel to a total amount of data flowing over the NR channel and the legacy channel; and use the indicator of the modification to selectively:
operate with blanking for the legacy channel based at least in part on the ratio satisfying a data threshold, or
operate without blanking for the legacy channel based at least in part on the ratio failing to satisfy the data threshold.

2 . The apparatus of claim 1 , wherein the NR channel and the legacy channel comprise downlink channels.

3 . The apparatus of claim 2 , wherein the indicator of the modification is further based at least in part on a quantity of downlink layers on the NR channel.

4 . The apparatus of claim 1 , wherein the indicator of the modification causes the network node to downgrade a capability associated with the NR channel.

5 . The apparatus of claim 1 , wherein the NR channel and the legacy channel comprise uplink channels.

6 . The apparatus of claim 1 , wherein the one or more memories and the one or more processors are further configured to transmit more data on the NR channel and to operate with blanking for the legacy channel based at least in part on the ratio satisfying a data threshold.

7 . The apparatus of claim 6 , wherein the indicator of the modification includes at least one of a modified buffer status report (BSR) or a request for one or more additional uplink grants from the network node.

8 . The apparatus of claim 1 , wherein the indicator of the modification includes a tracking area update (TAU).

9 . The apparatus of claim 1 , wherein the indicator of the modification of the data split is further based at least in part on an indicator of a quality of the legacy channel.

10 . An apparatus for wireless communication at a network node, comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more memories and the one or more processors configured to:
transmit, to a user equipment (UE), an indicator of a data split between a New Radio (NR) channel and a legacy channel; and
receive, from the UE, an indicator of a modification of the data split based at least in part on a ratio of an amount of data flowing over the NR channel to a total amount of data flowing over the NR channel and the legacy channel, wherein the indicator of the modification indicates a selection by the UE to:
operate with blanking for the legacy channel based at least in part on the ratio satisfying a data threshold, or
operate without blanking for the legacy channel based at least in part on the ratio failing to satisfy the data threshold.

11 . The apparatus of claim 10 , wherein the NR channel and the legacy channel comprise downlink channels.

12 . The apparatus of claim 11 , wherein the indicator of the modification is further based at least in part on a quantity of downlink layers on the NR channel.

13 . The apparatus of claim 10 , wherein the indicator of the modification causes the network node to downgrade a capability associated with the NR channel.

14 . The apparatus of claim 10 , wherein the NR channel and the legacy channel comprise uplink channels.

15 . The apparatus of claim 10 , wherein the indicator of the modification indicates that the UE is, based at least in part on the ratio satisfying a data threshold to transmit more data on the NR channel and to operate with blanking for the legacy channel.

16 . The apparatus of claim 15 , wherein the indicator of the modification includes at least one of a modified buffer status report (BSR) or a request for one or more additional uplink grants from the network node.

17 . The apparatus of claim 10 , wherein the indicator of the modification includes a tracking area update (TAU).

18 . The apparatus of claim 10 , wherein the indicator of the modification of the data split is further based at least in part on an indicator of a quality of the legacy channel.

19 . An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more memories and the one or more processors configured to:
receive, from a network node, an indicator of a data split between a New Radio (NR) channel and a legacy channel;
transmit, to the network node, an indicator of a modification of the data split based at least in part on an indicator of a quality of the legacy channel; and use the indicator of the modification to selectively:
operate with blanking for the legacy channel based at least in part on the quality satisfying a quality threshold, or
operate without blanking for the legacy channel based at least in part on the quality satisfying a quality threshold.

20 . The apparatus of claim 19 , wherein the indicator of the quality of the legacy channel includes a signal-to-noise ratio (SNR).

21 . The apparatus of claim 19 , wherein the indicator of the modification is further based at least in part on a proportion of data flowing over the NR channel to a total amount of data flowing over the NR channel and the legacy channel.

22 . The apparatus of claim 19 , wherein the indicator of the modification causes the network node to downgrade a capability associated with the NR channel.

23 . The apparatus of claim 19 , wherein the indicator of the modification includes a tracking area update (TAU).

24 . The apparatus of claim 19 , wherein the indicator of the modification is further based at least in part on a quantity of downlink layers on the NR channel.

25 . An apparatus for wireless communication at a network node, comprising:
one or more memories; and one or more processors coupled to the one or more memories, the one or more memories and the one or more processors configured to:
transmit, to a user equipment (UE), an indicator of a data split between a New Radio (NR) channel and a legacy channel; and
receive, from the UE, an indicator of a modification of the data split based at least in part on an indicator of a quality of the legacy channel, wherein the indicator of the modification indicates a selection by the UE to:
