To see all tables in another schema, you need to have one or more of the following system privileges:

SELECT ANY DICTIONARY
(SELECT | INSERT | UPDATE | DELETE) ANY TABLE

or the big-hammer, the DBA role.

With any of those, you can select:

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM DBA_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Without those system privileges, you can only see tables you have been granted some level of access to, whether directly or through a role.

SELECT DISTINCT OWNER, OBJECT_NAME 
  FROM ALL_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
   AND OWNER = '[some other schema]'

Lastly, you can always query the data dictionary for your own tables, as your rights to your tables cannot be revoked (as of 10g):

SELECT DISTINCT OBJECT_NAME 
  FROM USER_OBJECTS
 WHERE OBJECT_TYPE = 'TABLE'
