The WTRU may monitor a first control channel region and receive a first control channel transmission in the first control region indicating boundaries of a plurality of numerology blocks of a carrier. The WTRU may then receive a second control channel transmission in a second control channel of a second control region, wherein the second control channel transmission indicates one or more numerology parameters for at least one of the plurality of numerology blocks. The WTRU may then transmit or receive data based on the one or more numerology parameters of the one or more numerology blocks. ## Claims ### Claim 1 A method for a wireless transmit/receive unit (WTRU) comprising: receiving a first transmission including control channel region information of a plurality of numerology blocks, wherein each of the plurality of numerology blocks is within a carrier bandwidth, wherein each of the plurality of numerology blocks has a frequency range within the carrier bandwidth, an associated subcarrier spacing, and an associated symbol duration, wherein the received control channel region information indicates at least one control channel region for each of the plurality of numerology blocks, and a subset of time and frequency resources for each of the control channel regions within a respective numerology block of the plurality of numerology blocks; and receiving a control channel transmission based on the received first transmission, wherein the control channel transmission indicates one or more numerology parameters for at least one of the plurality of numerology blocks, wherein the control channel transmission is received in the indicated subset of time and frequency resources of a first control channel region of the at least one control channel region of the respective numerology block of the plurality of numerology blocks, and wherein the first control channel region has the subcarrier spacing and the symbol duration of the respective numerology block of the plurality of numerology blocks. ### Claim 2 (depends on 1) The method of claim 1, wherein at least one of the plurality of numerology blocks has a plurality of control channel regions having different frequency resources. ### Claim 3 (depends on 1) The method of claim 1, wherein the first control channel region has an associated beam. ### Claim 4 (depends on 1) The method of claim 1, wherein the received control channel transmission, in a first numerology block of the plurality of numerology blocks, indicates cross-numerology block scheduling, and wherein the method further comprises receiving a transmission in a different numerology block of the plurality of numerology blocks than the first numerology block of the plurality of numerology blocks. ### Claim 5 (depends on 1) The method of claim 1, wherein the plurality of numerology blocks are time division multiplexed. ### Claim 6 (depends on 1) The method of claim 1, wherein at least one of the control channel regions includes a plurality of search spaces. ### Claim 7 (depends on 1) The method of claim 1, wherein each of the control channel regions are periodically received in slots. ### Claim 8 (depends on 1) The method of claim 1, further comprising receiving data in a second transmission based on the one or more numerology parameters for the at least one of the plurality of numerology blocks. ### Claim 9 A wireless transmit/receive unit (WTRU) comprising: a transceiver; a processor, wherein the transceiver and the processor are configured to receive at least one message including control channel region information for a plurality of numerology blocks, wherein each of the plurality of numerology blocks is within a carrier bandwidth and each of the plurality of numerology blocks has a frequency range within the carrier bandwidth and an associated subcarrier spacing and symbol duration, and wherein the received control channel region information indicates at least one control channel region for each of the plurality of numerology blocks, and a subset of time and frequency resources for each of control channel regions within a respective numerology block of the plurality of numerology blocks, and the transceiver and the processor are configured to receive a control channel transmission based on the received control channel region information, wherein the control channel transmission is received in the indicated subset of time and frequency resources of a first control channel region of the at least one control channel region of the respective numerology block of the plurality of numerology blocks, and wherein the first control channel region has the subcarrier spacing and the symbol duration of the respective numerology block of the plurality of numerology blocks. ### Claim 10 (depends on 9) The WTRU of claim 9, wherein at least one of the plurality of numerology blocks has a plurality of control channel regions having different frequency resources. ### Claim 11 (depends on 9) The WTRU of claim 9, wherein the first control channel region has an associated beam. ### Claim 12 (depends on 9) The WTRU of claim 9, wherein the received control channel transmission, in a first numerology block of the plurality of numerology blocks, indicates cross-numerology block scheduling and the transceiver and the processor are configured to receive a transmission in a different numerology block of the plurality of numerology blocks than the first numerology block of the plurality of numerology blocks. ### Claim 13 (depends on 9) The WTRU of claim 9, wherein the plurality of numerology blocks are time division multiplexed. ### Claim 14 (depends on 9) The WTRU of claim 9, wherein at least one of the control channel regions includes a plurality of search spaces. ### Claim 15 (depends on 9) The WTRU of claim 9, wherein each of the control channel regions are periodically received in slots. ### Claim 16 (depends on 8) The WTRU of claim 8, wherein the transceiver and the processor are configured to receive data in a second transmission based on the one or more numerology parameters for the at least one of the plurality of numerology blocks.
