Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a first control channel in a first frequency band. The UE may determine that a bandwidth capability of the UE supports communicating on the first frequency band and at least a second frequency band. The UE may perform a channel measurement procedure on the first frequency band and the second frequency band concurrently. The UE may transmit a channel feedback message including information associated with the channel measurement procedure.

Claims (74)

1 . A method for wireless communication, comprising:

receiving, at a wireless device, a scheduling indicator on a first control channel in a first frequency band, wherein the wireless device is configured to perform channel measurement and reporting on the first frequency band;

determining that a data transmission is scheduled for the wireless device based at least in part on the received scheduling indicator;

identifying a second frequency band associated with the data transmission, wherein the wireless device is not configured by a network entity to perform channel measurement and reporting on one or more sub-carriers of the second frequency band, and wherein the second frequency band is non-overlapping with the first frequency band; and

performing, in association with the data transmission, a channel measurement procedure on the first frequency band and the second frequency band comprising the one or more sub-carriers, the channel measurement procedure performed concurrently on the first frequency band and the second frequency band.

2 . The method of claim 1 , further comprising:

transmitting a channel feedback message comprising information associated with the channel measurement procedure.

3 . The method of claim 2 , wherein:

the channel feedback message comprises one or more of a full bandwidth channel quality indicator (CQI), a best bandwidth indicator, a bandwidth differential, CQI, a subband report, a precoding matrix indicator (PMI), or combinations thereof.

4 . The method of claim 1 , further comprising:

autonomously determining, by the wireless device, to perform the channel measurement procedure on the second frequency band.

5 . The method of claim 1 , further comprising:

receiving a configuration message conveying a channel measurement request; and

performing the channel measurement procedure on the second frequency band based at least in part on the configuration message.

6 . The method of claim 1 , further comprising:

identifying a portion of subframes from a plurality of subframes to perform the channel measurement procedure; and

performing the channel measurement procedure on the second frequency band during the identified portion of subframes.

7 . The method of claim 1 , further comprising:

identifying a preconfigured set of frequency bands, wherein the first and second frequency bands are included in the preconfigured set of frequency bands.

8 . The method of claim 1 , further comprising:

identifying a set of frequency bands that are adjacent to the first frequency band, wherein the second frequency band is included in the set of frequency bands.

9 . The method of claim 1 , further comprising:

determining a set of wideband frequency bands associated with the wireless device monitoring a control channel; and

selecting the first and second frequency bands that are within the wideband frequency bands.

10 . The method of claim 1 , wherein:

the channel measurement procedure is performed according to a periodic schedule or an aperiodic schedule.

11 . The method of claim 1 , wherein:

the first frequency band comprises a 1.4 megahertz (MHz) bandwidth.

12 . The method of claim 1 , wherein:

the second frequency band comprises one of a 5 megahertz (MHz) bandwidth or a 20 MHz bandwidth.

13 . An apparatus for wireless communication at a wireless device, comprising:

at least one processor;

at least one memory in communication with the at least one processor; and

instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:

receive a scheduling indicator on a first control channel in a first frequency band, wherein the wireless device is configured to perform channel measurement and reporting on the first frequency band;

determine that a data transmission is scheduled for the apparatus based at least in part on the received scheduling indicator;

identify a second frequency band associated with the data transmission, wherein the wireless device is not configured by a network entity to perform channel measurement and reporting on one or more sub-carriers of the second frequency band, and wherein the second frequency band is non-overlapping with the first frequency band; and

perform, in association with the data transmission, a channel measurement procedure on the first frequency band and the second frequency band comprising the one or more sub-carriers, the channel measurement procedure performed concurrently on the first frequency band and the second frequency band.

14 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

transmit a channel feedback message comprising information associated with the channel measurement procedure.

15 . The apparatus of claim 14 , wherein:

16 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

autonomously determine to perform the channel measurement procedure on the second frequency band.

17 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

receive a configuration message conveying a channel measurement request; and

perform the channel measurement procedure on the second frequency band based at least in part on the configuration message.

18 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

identify a portion of subframes from a plurality of subframes to perform the channel measurement procedure; and

perform the channel measurement procedure on the second frequency band during the identified portion of subframes.

19 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

identify a preconfigured set of frequency bands, wherein the first and second frequency bands are included in the preconfigured set of frequency bands.

20 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

identify a set of frequency bands that are adjacent to the first frequency band, wherein the second frequency band is included in the set of frequency bands.

21 . The apparatus of claim 13 , wherein the instructions are further executable by the at least one processor to:

determine a set of wideband frequency bands associated with the wireless device monitoring a control channel; and

select the first and second frequency bands that are within the wideband frequency bands.

22 . The apparatus of claim 13 , wherein:

the channel measurement procedure is performed according to a periodic schedule or an aperiodic schedule.

23 . The apparatus of claim 13 , wherein:

the first frequency band comprises a 1.4 megahertz (MHz) bandwidth.

24 . The apparatus of claim 13 , wherein:

the second frequency band comprises one of a 5 megahertz (MHz) bandwidth or a 20 MHz bandwidth.

25 . An apparatus for wireless communication, comprising:

means for receiving, at the apparatus, a scheduling indicator on a first control channel in a first frequency band, wherein the apparatus is configured to perform channel measurement and reporting on the first frequency band;

means for determining that a data transmission is scheduled for the apparatus based at least in part on the received scheduling indicator;
