Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes system information, wherein the system information includes information associated with identifying a set of resources that carry synchronization communications, wherein the set of resources is included in a set of potential resources on which synchronization communications can be carried; and perform, based at least in part on a rate matching rule, de-rate matching associated with receiving the system information, wherein the rate matching rule is a rule associated with performing de-rate matching with respect to the set of potential resources. Numerous other aspects are provided.

Claims (74)

1. A method, comprising:

receiving, by a user equipment (UE), a communication that includes system information,

wherein the system information includes information associated with identifying a set of resources that carry synchronization communications,

wherein the set of resources is included in a set of potential resources on which synchronization communications can be carried, and

wherein the set of resources is a first set of resources;

performing, by the UE and based at least in part on a rate matching rule, de-rate matching associated with receiving the system information,

wherein the rate matching rule is a rule associated with performing de-rate matching with respect to the set of potential resources; and

receiving, by the UE, information that identifies a second set of resources that carries synchronization communications,

wherein the information that identifies the second set of resources temporarily overrides information that identifies the first set of resources.

2. The method of claim 1 , wherein the rate matching rule indicates that all resources, of the set of potential resources, carry synchronization communications, and

wherein the de-rate matching is performed based at least in part on de-rate matching around all resources of the set of potential resources.

3. The method of claim 1 , wherein the rate matching rule indicates no resources, of the set of potential resources, carry synchronization communications, and

wherein the de-rate matching is performed without de-rate matching around any resources of the set of potential resources.

4. The method of claim 1 , wherein the rate matching rule indicates that the set of resources is identified in control information, and

wherein the de-rate matching is performed based at least in part on de-rate matching in accordance with the control information.

5. The method of claim 4 , wherein the control information is downlink control information (DCI).

6. The method of claim 1 , wherein the system information is remaining minimum system information (RMSI), system information block 1 (SIB 1 ), or minimum system information (MSI).

7. The method of claim 1 , wherein the synchronization communications include at least one synchronization signal (SS) block.

8. The method of claim 1 , wherein the communication is associated with a physical downlink control channel (PDCCH).

9. The method of claim 1 , wherein the communication is associated with a physical downlink shared channel (PDSCH).

10. The method of claim 1 , wherein the set of potential resources includes resources associated with carrying 64 synchronization communications.

11. The method of claim 1 , wherein the communication is associated with a millimeter wave (mmW) frequency.

12. The method of claim 1 , wherein the system information is received based at least in part on performing the de-rate matching.

13. The method of claim 1 ,

wherein the communication is a first communication,

wherein receiving the information that identifies the second set of resources comprises:

receiving a second communication including control information,

wherein the control information includes the information that identifies the second set of resources,

wherein the information that identifies the first set of resources is determined based at least in part on the system informational, and

wherein the method further comprises:

determining information included in the second communication based at least in part on the information that identifies the second set of resources.

14. The method of claim 13 , wherein the second communication is a paging communication.

15. The method of claim 13 , wherein the second communication is a random access response.

16. The method of claim 13 , wherein the control information is downlink control information (DCI).

17. The method of claim 1 , wherein the communication is communicated in a mini-slot.

18. A device 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 communication that includes system information,

wherein the system information includes information associated with identifying a set of resources that carry synchronization communications,

wherein the set of resources is included in a set of potential resources on which synchronization communications can be carried, and

wherein the set of resources is a first set of resources; perform, based at least in part on a rate matching rule, de-rate matching associated with receiving the system information,

wherein the rate matching rule is a rule associated with performing de-rate matching with respect to the set of potential resources; and

receive information that identifies a second set of resources that carries synchronization communications,

wherein the information that identifies the second set of resources temporarily overrides information that identifies the first set of resources.

19. The device of claim 18 , wherein the rate matching rule indicates no resources, of the set of potential resources, carry synchronization communications, and

wherein the de-rate matching is performed without de-rate matching around any resources of the set of potential resources.

20. The device of claim 18 , wherein the system information is remaining minimum system information (RMSI), system information block 1 (SIB 1 ), or minimum system information (MSI).

21. The device of claim 18 , wherein the communication is associated with a physical downlink control channel (PDCCH).

22. The device of claim 18 , wherein the communication is associated with a physical downlink shared channel (PDSCH).

23. The device of claim 18 , wherein the set of potential resources includes resources associated with carrying 64 synchronization communications.

24. The device of claim 18 , wherein the communication is associated with a millimeter wave (mmW) frequency.

25. A method, comprising:

transmitting, by a base station, at least one synchronization communication,

wherein the at least one synchronization communication is transmitted in a set of resources,

wherein the set of resources is included in a set of potential resources on which synchronization communications can be carried, and

wherein the set of resources is a first set of resources; transmitting, by the base station, a communication including system information,

wherein the system information includes information associated with identifying the set of resources; and

transmitting, by the base station, information that identifies a second set of resources that carries synchronization communications

wherein the information that identifies the second set of resources temporarily overrides information that identifies the first set of resources.

26. The method of claim 25 , wherein the system information comprises remaining minimum system information (RMSI), system information block 1 (SIB 1 ), or minimum system information (MSI).

27. The method of claim 25 , wherein the synchronization communications include at least one synchronization signal (SS) block.
