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 comprising processing circuitry, the processing circuitry configured to cause a base station (BS) to:
transmit configuration information to a user equipment (UE), wherein the configuration information indicates a configuration of a plurality of frequency partitions of a system bandwidth;
transmit a physical downlink control channel (PDCCH) configuration for monitoring of a PDCCH, wherein the PDCCH configuration is transmitted using dedicated signaling to the UE, 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 a parameter; and
transmit the 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.

3. The apparatus of claim 2 , wherein the PDCCH is transmitted in the primary partition, wherein the PDCCH includes resource allocation information for the secondary partition, wherein the processing circuitry is further configured to cause the base station to perform machine type communication with the UE 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 cause the base station to transmit 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 transmitted 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 cause the base station to transmit 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, wherein the program instructions, when executed by processing circuitry, cause a base station to implement:
transmitting configuration information to a user equipment (UE), wherein the configuration information indicates a configuration of a plurality of frequency partitions of a system bandwidth;
transmitting a physical downlink control channel (PDCCH) configuration for monitoring of a PDCCH, wherein the PDCCH configuration is transmitted using dedicated signaling to the UE, 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 a parameter; and
transmitting the 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.

10. The non-transitory memory medium of claim 9 , wherein the PDCCH is transmitted in the primary partition, wherein the PDCCH includes resource allocation information for the secondary partition, wherein the program instructions, when executed by the processing circuitry, further cause the base station to perform machine type communication with the UE in the secondary partition using the resource allocation information for the secondary partition, wherein the configuration information is devoid of resource allocation information.

11. The non-transitory memory medium of claim 8 , wherein the program instructions, when executed by the processing circuitry, further cause the base station to transmit allocation information allocating at least a set of physical resource blocks (PRBs) within a secondary partition.

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

13. The non-transitory memory medium of claim 8 , wherein the program instructions, when executed by the processing circuitry, further cause the base station to transmit the PDSCH, wherein the PDCCH includes at least an initial orthogonal frequency-division multiplexing (OFDM) symbol of a subframe.

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

15. An apparatus, comprising:
at least one processor configured to cause a user equipment (UE) 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 is received via dedicated signaling to the UE, and specifies a periodicity and offset in time for the PDCCH monitoring, wherein the periodicity and the time offset are jointly defined by a parameter; and
receive the PDCCH in a first of the frequency partitions, wherein the PDCCH is time and frequency division multiplexed with a physical downlink shared channel (PDSCH).

16. The apparatus of claim 15 , wherein the frequency partitions include a primary partition and a secondary partition.

17. The apparatus of claim 16 , wherein the PDCCH is transmitted in the primary partition, wherein the PDCCH includes resource allocation information for the secondary partition, wherein the at least one processor is further configured to cause the UE to:
perform machine type communication with the UE in the secondary partition using the resource allocation information for the secondary partition, wherein the configuration information is devoid of resource allocation information.

18. The apparatus of claim 15 , wherein the at least one processor is further configured to cause the UE to:
transmit allocation information allocating at least a set of physical resource blocks (PRBs) within a secondary partition.

19. The apparatus of claim 15 , wherein the configuration information includes configuration information for frequency partitions of multiple component carriers (CCs).

20. The apparatus of claim 15 , wherein the PDCCH is received on a set of distributed physical resource blocks (PRBs) over consecutive orthogonal frequency-division multiplexing (OFDM) symbols.
