System information scheduling
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a system information (SI) message in an overlapped scheduling window; and identify the SI message based at least in part on at least one of: downlink control information (DCI) for the SI message, a system information radio network temporary identifier (SI-RNTI) of the SI message, a time location of the SI message in the overlapped scheduling window, a search space for the DCI, or a combination thereof. Numerous other aspects are provided.
1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving a downlink control information (DCI) identifying a resource allocation for a message in a scheduling window;
receiving the message containing a system information block (SIB) in the scheduling window according to the received DCI, wherein a SIB 1 (SIB1) within the scheduling window associated with the message allocated by the DCI can overlap with at least one SIB other than SIB1 within the scheduling window; and
identifying the SIB within the message based at least in part on the DCI,
wherein the DCI includes a single bit that has a first value to identify the SIB1 or a second value to identify any SIB other than SIB1.
2. The method of claim 1 , further comprising:
responsive to the identification of the SIB, selectively acquiring or not acquiring the message.
3. The method of claim 1 , wherein a system information block type of the message is identified based at least in part on a system information radio network temporary identifier (SI-RNTI) of the message.
4. The method of claim 1 , wherein the scheduling window is a configured overlapped scheduling window, further comprising monitoring a particular portion of the configured overlapped scheduling window, the particular portion including a time location of the message, to identify the message.
5. The method of claim 1 , wherein identifying the message is further based at least in part on a mapping between the message and a search space in which the DCI for the message is detected.
6. The method of claim 1 , wherein the SIB within the message is identified based at least in part on a time location of the scheduling window.
7. The method of claim 1 , wherein receiving the DCI comprises:
receiving the DCI in a first search space when the message comprises the SIB1 and receiving the DCI in a second search space when the message comprises the any SIB other than SIB1.
8. The method of claim 1 , wherein the message is received in a transmission using a beam.
9. The method of claim 1 , wherein the message is associated with a mapping between the message and a search space in which the DCI for the message is detected.
10. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
receive a downlink control information (DCI) identifying a resource allocation for a message in a scheduling window;
receive the message containing a system information block (SIB) in the scheduling window according to the received DCI, wherein a SIB 1 (SIB1) within the scheduling window associated with the message allocated by the DCI can overlap with at least one SIB other than SIB1 within the scheduling window; and
identify the SIB within the message based at least in part on the DCI,
wherein the DCI includes a single bit that has a first value to identify the SIB1 or a second value to identify any SIB other than SIB1.
11. The UE of claim 10 , wherein the one or more processors are further configured to:
responsive to the identification of the SIB, selectively acquire or not acquire the message.
12. The UE of claim 10 , wherein a system information block type of the message is identified based at least in part on a system information radio network temporary identifier (SI-RNTI) of the message.
13. The UE of claim 10 , wherein the scheduling window is a configured overlapped scheduling window, and wherein the UE is configured to monitor a particular portion of the configured overlapped scheduling window, the particular portion including a time location of the message, to identify the message.
14. The UE of claim 10 , wherein identifying the message is further based at least in part on a mapping between the message and a search space in which the DCI for the message is detected.
15. The UE of claim 10 , wherein the SIB within the message is identified based at least in part on a time location in the scheduling window.
16. The UE of claim 10 , wherein the one or more processors, when receiving the DCI, are configured to:
receive the DCI in a first search space when the message comprises the SIB1 and receive the DCI in a second search space when the message comprises any SIB other than SIB1.
17. A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
receive a downlink control information (DCI) identifying a resource allocation for a message in a scheduling window;
receive the message containing a system information block (SIB) in the scheduling window according to the received DCI, wherein a SIB 1 (SIB1) within the scheduling window associated with the message allocated by the DCI can overlap with at least one SIB other than SIB1 within the scheduling window; and
identify the SIB within the message based at least in part on the DCI,
wherein the DCI includes a single bit that has a first value to identify the SIB1 or a second value to identify any SIB other than SIB1.
18. An apparatus for wireless communication, comprising:
means for receiving a downlink control information (DCI) identifying a resource allocation for a message in a scheduling window;
means for receiving the message containing a system information block (SIB) in the scheduling window according to the received DCI, wherein a SIB 1 (SIB1) within the scheduling window associated with the message allocated by the DCI can overlap with at least one SIB other than SIB1 within the scheduling window; and
means for identifying the SIB within the message based at least in part on the DCI,
wherein the DCI includes a single bit that has a first value to identify the SIB1 or a second value to identify any SIB other than SIB1.
19. The apparatus of claim 18 , further comprising:
responsive to the identification of the SIB, means for selectively acquiring or not acquiring the message.
20. The apparatus of claim 18 , wherein a system information block type of the message is identified based at least in part on a system information radio network temporary identifier (SI-RNTI) of the message.
21. The apparatus of claim 18 , wherein the scheduling window is a configured overlapped scheduling window, and wherein the apparatus includes means for monitoring a particular portion of the configured overlapped scheduling window, the overlapping scheduling window including a time location of the message, to identify the message.
