Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, scheduling information associated with a data communication, the scheduling information indicating a resource allocation associated with the data communication. The UE may receive, from the network node, the data communication and system information that is superimposed on the resource allocation associated with the data communication. Numerous other aspects are described.

First claim

What is claimed is:

1 . A user equipment (UE) for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to cause the UE to:
receive, from a network node, scheduling information associated with a data communication, the scheduling information indicating a resource allocation associated with the data communication;
receive, from the network node, the data communication and system information that is superimposed on the resource allocation; and
decode a signal to obtain the data communication and the system information.

2 . The UE of claim 1 ,
wherein the one or more processors are further configured to cause the UE to:
receive, from the network node, an indication of a timing of a transmission of the system information,
wherein receiving the data communication and the system information is associated with receiving the indication of the timing.

3 . The UE of claim 2 ,
wherein the indication of the timing includes an indication of scheduling associated with a set of system information blocks (SIBs) to be superimposed with data communications, wherein the system information is associated with a SIB from the set of SIBs.

4 . The UE of claim 1 ,
wherein the data communication is associated with a first signal power, and wherein the system information is associated with a second signal power.

5 . The UE of claim 4 ,
wherein a difference between the first signal power and the second signal power satisfies a threshold.

6 . The UE of claim 1 ,
wherein the data communication is associated with a first signal-to-noise ratio (SNR), and wherein the system information is associated with a second SNR.

7 . The UE of claim 1 ,
wherein, to decode the signal, the one or more processors are configured to cause the UE to:
decode the signal to obtain the data communication;
remove the data communication from the signal via successive interference cancellation (SIC); and
decode the signal, after removing the data communication, to obtain the system information.

8 . The UE of claim 1 ,
wherein the system information is periodically communicated via superimposing with data communications.

9 . The UE of claim 1 ,
wherein the one or more processors are further configured to cause the UE to:
transmit, to the network node, a capability report indicating a decoding capability of the UE associated with decoding superimposed system information.

10 . The UE of claim 6 , wherein a code rate of the system information is associated with a decodable code rate for the UE and the second SNR.

11 . A network node for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the memory, configured to cause the network node to:
receive a capability report indicating a decoding capability of a user equipment (UE) associated with decoding superimposed system information;
transmit, based at least in part on the capability report, scheduling information, for the UE, associated with a data communication, the scheduling information indicating a resource allocation associated with the data communication; and
transmit, based at least in part on the capability report, the data communication and system information that is superimposed on the resource allocation.

12 . The network node of claim 11 ,
wherein the one or more processors are further configured to cause the network node to:
transmit an indication of a timing of a transmission of the system information.

13 . The network node of claim 11 ,

18 . The method of claim 17 , further comprising:
receiving, from the network node, an indication of a timing of a transmission of the system information,
wherein receiving the data communication and the system information is associated with receiving the indication of the timing.

19 . The method of claim 18 ,
wherein the indication of the timing includes an indication of scheduling associated with a set of system information blocks (SIBs) to be superimposed with data communications, wherein the system information is associated with a SIB from the set of SIBs.

20 . The method of claim 17 ,
wherein the data communication is associated with a first signal power, and wherein the system information is associated with a second signal power.

21 . The method of claim 20 ,
