Abstract

Methods and apparatus for providing a resource element identification system to process received uplink transmissions. In an embodiment, a method is provided that includes receiving one or more symbols from an uplink transmission. Each symbol comprises resource elements. The method also includes categorizing the resource elements into a plurality of categories to generated categorized resource elements, and forwarding the categorized resource elements to downstream processing functions.

Claims (25)

1. A method for facilitating network communication, comprising:

receiving one or more symbols from an uplink transmission, wherein receiving one or more symbols includes identifying resource elements containing data hits and uplink control information (“UCI”) bits scattered throughout the resource elements for each symbol;

categorizing the resource elements into a plurality of categories indexing some resource elements containing UCI and some resource elements containing data to generate categorized resource elements, wherein categorizing includes generating a first category containing data and second channel state information (CSI2), a second category containing acknowledgment (ACK) information, a third category containing first channel state information (CSI1); and

forwarding the categorized resource elements to downstream processing functions for facilitating optional treatments.

2. The method of claim 1 , wherein the symbols are received from a new radio (NR) uplink transmission.

3. The method of claim 1 , further comprising soft-demapping the categorized resource elements based on their associated categories.

4. The method of claim 1 , further comprising descrambling the categorized resource elements based on their associated categories.

5. The method of claim 1 , further comprising combining and extracting uplink control information from the categorized resource elements.

6. The method of claim 1 , further comprising calculating signal to interference noise ratios (SINR) for each category of the resource elements.

7. The method of claim 1 , further comprising receiving the symbols from one of a layer demapper and a despreader.

8. An apparatus for facilitating network communication, comprising:

an input interface that receives one or more symbols, wherein each symbol includes resource elements containing data bits and uplink control information (“UCI”) bits wherein the UCI bits are scattered throughout the resource elements;

a categorizer coupled to the input interface and configured to categorize the resource elements into a plurality of categories indexing some resource elements containing UCI and some resource elements containing data to generate categorized resource elements, wherein the categorizer generates a first category containing data and second channel state information (CSI2), a second category containing acknowledgment (ACK) information, a third category containing first channel state information (CSI1); and

an output interface coupled to the categorizer and operable to output the categorized resource elements to downstream processing functions for facilitating optional treatments.

9. The apparatus of claim 8 , wherein the symbols are received in a new radio (NR) uplink transmission.

10. The apparatus of claim 8 , further comprising a soft-demapper that soft-demaps the categorized resource elements based on their associated categories.

11. The apparatus of claim 8 , further comprising a descrambler that descrambles the categorized resource elements based on their associated categories.

12. The apparatus of claim 8 , further comprising a combiner/extractor that combines and extracts uplink control information from the categorized resource elements.

13. The apparatus of claim 8 , further comprising a calculator that calculates signal to interference noise ratios (SINR) for each category of the resource elements.

14. The apparatus of claim 8 , wherein the input interface receives the symbols from one of a layer demapper and a despreader.

15. An apparatus for facilitating network communication, comprising:

means for receiving one or more symbols from an uplink transmission, wherein means for receiving one or more symbols includes means for identifying resource elements containing data bits and uplink control information (“UCI”) bits scattered throughout the resource elements for each symbol;

means for categorizing the resource elements into a plurality of categories indexing some resource elements containing UCI and some resource elements containing data to generate categorized resource elements, wherein means for categorizing includes means for generating a first category containing data and second channel state information (CSI2), a second category containing acknowledgment (ACK) information, a third category containing first channel state information (CSI1); and

means for forwarding the categorized resource elements to downstream processing functions for facilitating optional treatment.

16. The apparatus of claim 15 , wherein means for receiving one or more symbols includes means for obtaining symbols received from a 5G uplink transmission.
