Abstract

A system facilitating compact signaling design for reserved resource configuration via a multi-dimensional bitmap is provided for a wireless communication system. A method comprises: determining a multi-dimensional bitmap (MDB) in time and frequency domains, wherein the time domain is represented by an orthogonal frequency division multiplexed (OFDM) symbol and the frequency domain is represented by an OFDM subcarrier. The determining comprises: selecting a group of reserved resource allocations of the MDB in which data information is not to be communicated; assigning a first value for the OFDM multiplexed symbol and the OFDM subcarrier according to a location of elements of the group of reserved resource allocations; and assigning, to other portions of the MDB other than the group of reserved resource allocations, a second value distinct from the first value. The method also comprises facilitating, by the device, transmitting the MDB to a mobile device.

Claims

1. An apparatus, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

determining a multi-dimensional bitmap in a time domain and a frequency domain, wherein the determining comprises;

selecting a group of reserved resource allocations of the multi-dimensional bitmap in which data information is not to be communicated and in which signaling information is to be communicated; and

assigning, to portions of the multi-dimensional bitmap other than the group of reserved resource allocations, a defined value, wherein a total available reserved resource allocation for the signaling information is a first number of bits in a first bitmap of the multi-dimensional bitmap combined with a second number of bits in a second bitmap of the multi-dimensional bitmap.

2. The apparatus of claim 1, wherein the assigning to the portions of the multi-dimensional bitmap is for usage by a mobile device to facilitate performance of rate matching.

3. The apparatus of claim 1, wherein a reserved resource allocation of the group of reserved resource allocations is determined for one resource element of the multi-dimensional bitmap.

4. The apparatus of claim 1, wherein the multi-dimensional bitmap determined in the time domain comprises a first single dimensional bitmap of the multi-dimensional bitmap.

5. The apparatus of claim 4, wherein the multi-dimensional bitmap determined in the frequency domain comprises a second single dimensional bitmap of the multi-dimensional bitmap.

6. A method, comprising:

obtaining, by a device comprising a processor, a multi-dimensional bitmap in a time domain and a frequency domain, wherein the obtaining comprises;

selecting a group of reserved resource allocations of the multi-dimensional bitmap in which data information is not to be communicated and in which signaling information is to be communicated; and

assigning, to portions of the multi-dimensional bitmap other than the group of reserved resource allocations, a defined value, wherein a total available reserved resource allocation for the signaling information is a first number of bits in a first bitmap of the multi-dimensional bitmap combined with a second number of bits in a second bitmap of the multi-dimensional bitmap.

7. The method of claim 6, wherein the assigning to the portions of the multi-dimensional bitmap is for mobile device usage to facilitate performance of rate matching.

8. The method of claim 6, wherein a reserved resource allocation of the group of reserved resource allocations is determined for one resource element of the multi-dimensional bitmap.

9. The method of claim 6, wherein the multi-dimensional bitmap in the time domain comprises a first single dimensional bitmap of the multi-dimensional bitmap.

generating a multi-dimensional bitmap in a time domain and generating the multi-dimensional bitmap in a frequency domain, wherein the generating comprises;

selecting a group of reserved resource allocations of the multi-dimensional bitmap in which data information is not to be communicated; and

assigning, to portions of the multi-dimensional bitmap other than the group of reserved resource allocations, a defined value, wherein a total available reserved resource allocation for signaling information is a first number of bits in a first bitmap of the multi-dimensional bitmap combined with a second number of bits in a second bitmap of the multi-dimensional bitmap.

15. The non-transitory machine-readable storage medium of claim 14, wherein the assigning to the portions of the multi-dimensional bitmap is for use by a mobile device to facilitate a performance of rate matching by the mobile device.

16. The non-transitory machine-readable storage medium of claim 14, wherein a reserved resource allocation of the group of reserved resource allocations is determined for one resource element of the multi-dimensional bitmap.
