Abstract

A method for wireless communication at a user equipment (UE) includes receiving, from a base station, an indication of uplink transmission resources allocated for a paging response to a paging indication, receiving the paging indication from the base station, and transmitting, to the base station, the paging response to the received paging indication. The paging response is transmitted on at least one of the uplink transmission resources allocated for the paging response. A method for wireless communication at a base station includes identifying uplink transmission resources for paging responses, transmitting an indication of the uplink transmission resources allocated for paging responses, transmitting a paging indication to at least one UE, and receiving a paging response from one or more UEs using a receive beam sweep. The paging response is received on an associated beam on at least one of the uplink transmission resources allocated for paging responses.

Claims

1. A method for wireless communication at a user equipment (UE), comprising:

receiving a paging indication from a base station, wherein the paging indication indicates at least one uplink transmission resource allocated for a paging response; and

transmitting, in response to the received paging indication, the paging response to the base station on the at least one uplink transmission resource allocated for the paging response.

2. The method of claim 1, further comprising:

transmitting information for a base station beam in the paging response.

3. The method of claim 2, further comprising:

receiving paging information from the base station, the paging information transmitted by the base station based at least in part on the transmitted beam information.

4. The method of claim 2, further comprising:

identifying the base station beam based at least in part on a link quality of a synchronization signal.

5. The method of claim 4, wherein the synchronization signal comprises a primary synchronization signal (PSS), or a secondary synchronization signal (SSS), or a demodulation reference signal (DMRS) of a physical broadcast channel (PBCH), or a PBCH, or a combination thereof.

6. The method of claim 1, wherein the uplink transmission resource identifies an uplink transmission time, or a subcarrier region, or a preamble, or a combination thereof.

8. The method of claim 1, wherein the paging indication comprises a paging index associated with a group of mobile subscriber identities, and the paging response is transmitted on a paging index-specific uplink transmission resource.

9. The method of claim 8, wherein the paging indication comprises a paging index-specific preamble.

10. The method of claim 8, further comprising:

receiving, in response to transmitting the paging response, at least one UE identifier associated with a page corresponding to the paging index.

11. The method of claim 8, further comprising:

receiving with the paging index an indication of a type of mobile subscriber associated with the paging index.

12. The method of claim 1, wherein the paging indication includes a search space for a paging message, the search space comprises one or more slots or subframes for the paging message.

13. The method of claim 12, further comprising:

monitoring resources indicated in the search space for the paging message.

15. The method of claim 1, further comprising:

selecting the at least one uplink transmission resource on which the paging response is transmitted by selecting from a number of opportunities for paging responses within a time interval and frequency range of the uplink transmission resources allocated for paging responses, wherein the number of opportunities is allocated based at least in part on a presence or absence of time synchronization of UEs within a coverage area of the base station.

14. (canceled)

16. A method for wireless communication at a base station, comprising:

transmitting a paging indication to at least one user equipment (UE), wherein the paging indication indicates at least one uplink transmission resource allocated for a paging response;
