Unfortunately, there is no clear-cut way to do this currently: However, as jasonaden commented on the linked thread,

This could be done manually by merging the old and new query params, removing the key you don't want.

Here is one way to do that:

Let's say you have your queryParams stored in some properties.

class MyComponent() {
  id: string;
  pos: string;
  sd: string;

  constructor(private route: ActivatedRoute, private router: Router) {}

  ngOnInit() {
    this.route.url.subscribe(next => {
      const paramMap = next.queryParamMap; = paramMap.get('id');
      this.pos = paramMap.get('pos'); = paramMap.get('sd');

A method to clear the pos parameter would look like this:

clearPosParam() {
    { relativeTo: this.route, queryParams: { id:, sd: } }

This will effectively navigate to the current route and clear your pos query parameter, keeping your other query parameters the same.

  queryParams: {
    yourParamName: null,
    youCanRemoveMultiple: null,
  queryParamsHandling: 'merge'

This option is simpler and requires less work to ensure you are not removing other params. You also do not need to worry about cleaning up an observable subscription when your component is destroyed.
