Abstract

A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus retrieves a particular number corresponding to a UE. To retrieve the particular number, the apparatus may receive the particular number through a channel request from the UE. Alternately, the apparatus may assign the particular number to the UE in order to retrieve the particular number. The apparatus determines a resource block within a coverage class based on the particular number. To determine the resource block, the apparatus maps the particular number to a resource block number within the coverage class using a hash function. The resource block number identifies the resource block. The apparatus transmits a device-specific control message to the UE using the determined resource block.

First claim

What is claimed is:

1 . A method of wireless communication, comprising:
retrieving a particular number corresponding to a user equipment (UE); determining a resource block based on the particular number; and transmitting a device-specific control message to the UE using the resource block.

2 . The method of claim 1 , wherein the determining the resource block comprises determining the resource block within a coverage class.

3 . The method of claim 2 , wherein the retrieving the particular number comprises receiving a channel request from the UE, the channel request comprising the particular number.

4 . The method of claim 2 , wherein the determining the resource block further comprises mapping the particular number to a resource block number within the coverage class using a hash function, wherein the resource block number identifies the resource block.

5 . The method of claim 4 , wherein the hash function defines the resource block number as a remainder of a division of the particular number by a number of resource blocks available for the coverage class.

6 . The method of claim 1 , wherein the retrieving the particular number comprises assigning the particular number to the UE.

7 . The method of claim 1 further comprising:
transmitting, in response to the resource block being used by another UE, the device-specific control message to the UE using a neighboring resource block that is immediately before or immediately after the resource block in time.

8 . The method of claim 1 , wherein the determining the resource block based on the particular number comprises determining a plurality of resource blocks based on the particular number,
the method further comprising selecting one resource block from the plurality of resource blocks, wherein the transmitting the device-specific control message comprises transmitting the device-specific control message to the UE using the one resource block.

9 . The method of claim 1 further comprising:
transmitting, in response to the resource block being used by another UE, the device-specific control message to the UE using a reserved resource block.

10 . A method of wireless communication of a user equipment (UE), comprising:
retrieving a particular number; determining a resource block for the UE based on the particular number; and monitoring the resource block for a device-specific control message from a base station.

11 . The method of claim 10 , wherein the retrieving the particular number comprises receiving the particular number from the base station.

12 . The method of claim 10 , wherein the determining the resource block comprises determining the resource block within a coverage class.

13 . The method of claim 12 , wherein the determining the resource block further comprises mapping the particular number to a resource block number within the coverage class using a hash function, wherein the resource block number identifies the resource block.

14 . The method of claim 10 further comprising:
monitoring a neighboring resource block that is immediately before or immediately after the resource block in time for the device-specific control message.

15 . The method of claim 10 , wherein the determining the resource block for the UE based on the particular number comprises determining a plurality of resource blocks based on the particular number,
wherein the monitoring the resource block comprises monitoring the plurality of resource blocks for the device-specific control message from the base station.

16 . The method of claim 10 further comprising:
monitoring a reserved resource block for the device-specific control message.

17 . An apparatus for wireless communication, comprising:
a memory; and at least one processor coupled to the memory and configured to:
retrieve a particular number corresponding to a user equipment (UE);
determine a resource block based on the particular number; and
transmit a device-specific control message to the UE using the resource block.

18 . The apparatus of claim 17 , wherein, to determine the resource block, the at least one processor is configured to determine the resource block within a coverage class.

19 . The apparatus of claim 18 , wherein, to retrieve the particular number, the at least one processor is configured to receive a channel request from the UE, the channel request comprising the particular number.

20 . The apparatus of claim 18 , wherein, to determine the resource block, the at least one processor is further configured to map the particular number to a resource block number within the coverage class using a hash function, wherein the resource block number identifies the resource block.

21 . The apparatus of claim 20 , wherein the hash function defines the resource block number as a remainder of a division of the particular number by a number of resource blocks available for the coverage class.

22 . The apparatus of claim 17 , wherein the at least one processor is further configured to:
transmit, in response to the resource block being used by another UE, the device-specific control message to the UE using a neighboring resource block that is immediately before or immediately after the resource block in time.

23 . The apparatus of claim 17 , wherein the at least one processor is further configured to:
transmit, in response to the resource block being used by another UE, the device-specific control message to the UE using a reserved resource block.

24 . The apparatus of claim 17 , wherein, to determine the resource block based on the particular number, the at least one processor is further configured to determine a plurality of resource blocks based on the particular number, and to select one resource block from the plurality of resource blocks,
wherein, to transmit the device-specific control message, the at least one processor is further configured to transmit the device-specific control message to the UE using the one resource block.

25 . An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
a memory; and at least one processor coupled to the memory and configured to:
retrieve a particular number;
determine a resource block for the UE based on the particular number; and
monitor the resource block for a device-specific control message from a base station.

26 . The apparatus of claim 25 , wherein, to determine the resource block, the at least one processor is configured to determine the resource block within a coverage class.

27 . The apparatus of claim 26 , wherein, to determine the resource block, the at least one processor is further configured to map the particular number to a resource block number within the coverage class using a hash function, wherein the resource block number identifies the resource block.

28 . The apparatus of claim 25 , wherein the at least one processor is further configured to:
monitor a neighboring resource block that is immediately before or immediately after the resource block in time for the device-specific control message.

29 . The apparatus of claim 25 , wherein, to determine the resource block for the UE based on the particular number, the at least one processor is further configured to determine a plurality of resource blocks based on the particular number,
wherein, to moni
