receiving a plurality of uplink transmissions from the one or more UEs, the plurality of uplink transmissions being received concurrently in the carriers.

5. The method of claim 4, wherein:

a first portion of each of the M carriers is allocated for downlink transmissions and a second portion of each of the carriers is allocated for uplink transmissions; and the second portion is located subsequent to the first portion in a time domain.

6. The method of claim 2, wherein:

each of the M carriers is associated with a respective hopping sequence across a plurality of frames; and

each respective hopping sequence includes a respective fixed offset from contiguous non-anchor channels in the carrier.

7. The method of claim 6, wherein the each respective hopping sequence comprises a pseudo-random hopping sequence.

8. The method of claim 1, wherein the communicating with the at least one UE using the narrowband frequency hopping pattern comprises:

concurrently transmitting a discovery reference signal (DRS) in each of the plurality of anchor channels at a start of each hopping frame.

9. The method of claim 2, wherein each of the M carriers have a same frame structure.

10. The method of claim 2, wherein a total bandwidth of each of the carriers meets a bandwidth threshold criteria.

11. The method of claim 3, wherein:

the one or more UEs include a single UE;

the plurality of downlink transmissions include an initial downlink transmission transmitted on one of theMcarriers and downlink retransmissions transmitted on a subset of the carriers.

12. The method of claim 3, wherein the plurality of downlink transmissions includes a reservation signal on each of the carriers when a data transmission is unavailable.

13. The method of claim 2, wherein the communicating with the at least one UE using the narrowband frequency hopping pattern comprises:

concurrently transmitting a first downlink transmission to a first UE in a first portion of each of theMcarriers; and

concurrently transmitting a second downlink transmission to a second UE in a second portion of each of the M carriers, the second portion being subsequent to the first portion in a time domain.

14. The method of claim 13, wherein the communicating with the at least one UE using the narrowband frequency hopping pattern further comprises:

receiving a first uplink transmission in a third portion of a first carrier of the M carriers; and

receiving a second uplink transmission in the third portion of a second carrier of the M carriers, the first uplink transmission and the second uplink transmission being received concurrently, and the third portion being adjacent to the second portion in the time domain.

15. The method of claim 1, wherein the at least one non-anchor channel includes a single non-anchor channel.

16. A method of wireless communication of a user equipment (UE), comprising: receiving information indicating a narrowband frequency hopping pattern within from a base station, the narrowband frequency hopping pattern corresponding to a plurality of frames, the plurality of frames including at least one non-anchor channel and being associated with a plurality of anchor channels; and

communicating with the base station using the narrowband frequency hopping pattern, wherein communication on the plurality of anchor channels occurs during the same frames.
