Abstract

Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

First claim

What is claimed is:

1. An apparatus for a user equipment (UE), the apparatus comprising transceiver circuitry and processing circuitry, the processing circuitry configured to cause the transceiver circuitry to:
receive configuration information from a base station, the configuration information directing the configuration of a plurality of frequency partitions of a system bandwidth;
monitor a physical downlink control channel (PDCCH) according to a PDCCH configuration, wherein the PDCCH configuration specifies a periodicity and offset in time for the PDCCH monitoring, wherein the periodicity and the time offset are jointly defined by an index which is configured by dedicated signaling to the UE; and
receive the physical downlink control channel (PDCCH) in a first of the frequency partitions, wherein the PDCCH is time and frequency division multiplexed with a physical downlink shared channel (PDSCH).

2. The apparatus of claim 1 , wherein the frequency partitions include a primary partition and a secondary partition, wherein the primary partition is configured for a communication type other than machine type communication (MTC), wherein the secondary partition is configured for MTC.

3. The apparatus of claim 2 , wherein the PDCCH is received from the primary partition, wherein the PDCCH includes resource allocation information for the secondary partition, wherein, if the UE is an MTC UE, the processing circuitry is configured to direct the transceiver circuitry to perform machine type communication in the secondary partition using the resource allocation information for the secondary partition, wherein the configuration information is devoid of resource allocation information.

4. The apparatus of claim 1 , wherein the processing circuitry is configured to direct the transceiver circuitry to:
receive allocation information allocating at least a set of physical resource blocks (PRBs) within a secondary partition.

5. The apparatus of claim 1 , wherein the PDCCH is received on a set of distributed physical resource blocks (PRBs) over consecutive orthogonal frequency-division multiplexing (OFDM) symbols.

6. The apparatus of claim 1 , wherein processing circuitry is configured to direct the transceiver circuitry to:
receive the PDSCH, wherein the PDCCH includes at least an initial orthogonal frequency-division multiplexing (OFDM) symbol of a subframe.

7. The apparatus of claim 1 , wherein the configuration information includes configuration information for frequency partitions of multiple component carriers (CCs).

8. A non-transitory memory medium storing program instructions for a user equipment (UE), wherein the program instructions, when executed by processing circuity, cause the UE to implement:
receiving configuration information from a base station, the configuration information directing the configuration of a plurality of frequency partitions of a system bandwidth;
monitoring a physical downlink control channel (PDCCH) according to a PDCCH configuration, wherein the PDCCH configuration specifies a periodicity and offset in time for the PDCCH monitoring, wherein the periodicity and the time offset are jointly defined by an index which is configured by dedicated signaling to the UE; and
receiving the physical downlink control channel (PDCCH) in a first of the frequency partitions, wherein the PDCCH is time and frequency division multiplexed with a physical downlink shared channel (PDSCH).

9. The non-transitory memory medium of claim 8 , wherein the frequency partitions include a primary partition and a secondary partition, wherein the primary partition is configured for a communication type other than machine type communication (MTC), wherein the secondary partition is configured for MTC.

10. The non-transitory memory medium of claim 8 , wherein the program instructions, when executed by processing circuity, further cause the UE to implement:
receiving allocation information allocating at least a set of physical resource blocks (PRBs) within a secondary partition.

11. The non-transitory memory medium of claim 8 , wherein the PDCCH is received on a set of distributed physical resource blocks (PRBs) over consecutive orthogonal frequency-division multiplexing (OFDM) symbols.

12. The non-transitory memory medium of claim 8 , wherein the program instructions, when executed by processing circuity, further cause the UE to implement:
receiving the PDSCH, wherein the PDCCH includes at least an initial orthogonal frequency- division multiplexing (OFDM) symbol of a subframe.

13. The non-transitory memory medium of claim 8 , wherein the configuration information includes configuration information for frequency partitions of multiple component carriers (CCs).

14. A method for operating a user equipment (UE), the method comprising:
receiving configuration information from a base station, the configuration information directing the configuration of a plurality of frequency partitions of a system bandwidth;
monitoring a physical downlink control channel (PDCCH) according to a PDCCH configuration, wherein the PDCCH configuration specifies a periodicity and offset in time for the PDCCH monitoring, wherein the periodicity and the time offset are jointly defined by an index which is configured by dedicated signaling to the UE; and
receiving the physical downlink control channel (PDCCH) in a first of the frequency partitions, wherein the PDCCH is time and frequency division multiplexed with a physical downlink shared channel (PDSCH).

15. The method of claim 14 , wherein the frequency partitions include a primary partition and a secondary partition, wherein the primary partition is configured for a communication type other than machine type communication (MTC), wherein the secondary partition is configured for MTC.

16. The method of claim 15 , wherein the PDCCH is received from the primary partition, wherein the PDCCH includes resource allocation information for the secondary partition, wherein, if the UE is an MTC UE, the method further comprises:
directing the transceiver circuitry to perform machine type communication in the secondary partition using the resource allocation information for the secondary partition, wherein the configuration information is devoid of resource allocation information.

17. The method of claim 14 , further comprising:
receiving allocation information allocating at least a set of physical resource blocks (PRBs) within a secondary partition.

18. The method of claim 14 , wherein the PDCCH is received on a set of distributed physical resource blocks (PRBs) over consecutive orthogonal frequency-division multiplexing (OFDM) symbols.
