Abstract

User equipment (UE) may receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB). Further, the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth. The MIB includes an indication of frequency resources and time resources for use in acquiring additional system information. The UE may further acquire the additional system information using the indication of the frequency resources and the time resources.

Claims

1. A user equipment (UE) comprising:

a transceiver; and

a processor, operatively coupled to the transceiver;

wherein

the transceiver and the processor are configured to receive a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB), the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth, wherein the MIB includes an indication of frequency resources and time resources for use in acquiring additional system information; and

the transceiver and the processor are configured to acquire the additional system information using the indication of the frequency resources and the time resources, wherein the indicated frequency resources and the time resources include control information for use by the UE to acquire a system information block 1.

2. The UE of claim 1 wherein the indication of the frequency resources and the time resources is within a first portion of the cell bandwidth.

3. The UE of claim 1 wherein the transceiver and the processor are configured to receive control information and physical downlink shared channel (PDSCH) transmissions with the first portion of the cell bandwidth and not in other portions of the cell bandwidth.

4. The UE of claim 2 wherein the transceiver and the processor are configured to receive control information indicating a plurality of bandwidth portions of the cell bandwidth, wherein the plurality of bandwidth portions includes the first portion.

5. The UE of claim 4 wherein the transceiver and the processor are configured to switch between the plurality of bandwidth portions at different times.

6. The UE of claim 1 wherein the indicated frequency resources and the time resources include a second MIB.

7. A method performed by a user equipment (UE), the method comprising:

receiving a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB), the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth, wherein the MIB includes an indication of frequency resources and time resources for use in acquiring additional system information; and

acquiring the additional system information using the indication of the frequency resources and the time resources, wherein the indicated frequency resources and the time resources include control information for use by the UE to acquire a system information block 1.

8. The method of claim 7 wherein the indication of the frequency resources and the time resources is within a first portion of the cell bandwidth.

9. The method of claim 7, further comprising:

receiving control information and physical downlink shared channel (PDSCH) transmissions with the first portion of the cell bandwidth and not in other portions of the cell bandwidth.

10. The method of claim 8, further comprising:

receiving control information indicating a plurality of bandwidth portions of the cell bandwidth, wherein the plurality of bandwidth portions includes the first portion.

11. The method of claim 10, further comprising:

switching between the plurality of bandwidth portions at different times.

12. The method of claim 7 wherein the indicated frequency resources and the time resources include a second MIB.

13. At least one non-transient computer readable medium containing program instructions to perform a method of:

receiving a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) including a master information block (MIB), the PSS, SSS and PBCH are in a first bandwidth of a cell having a cell bandwidth, wherein the first bandwidth is a first portion of the cell bandwidth, wherein the MIB includes an indication of frequency resources and time resources for use in acquiring additional system information; and

acquiring the additional system information using the indication of the frequency resources and the time resources, wherein the indicated frequency resources and the time resources include control information for use by the UE to acquire a system information block 1.

14. The at least one non-transient computer readable medium of claim 13 wherein the indication of the frequency resources and the time resources is within a first portion of the cell bandwidth.

15. The at least one non-transient computer readable medium of claim 13, further comprising:

receiving control information and physical downlink shared channel (PDSCH) transmissions with the first portion of the cell bandwidth and not in other portions of the cell bandwidth.

16. The at least one non-transient computer readable medium of claim 14, further comprising:

receiving control information indicating a plurality of bandwidth portions of the cell bandwidth, wherein the plurality of bandwidth portions includes the first portion.

17. The at least one non-transient computer readable medium of claim 16, further comprising:

switching between the plurality of bandwidth portions at different times.

18. The at least one non-transient computer readable medium of claim 13 wherein the indicated frequency resources and the time resources include a second MIB.
