Abstract
Apparatus, methods, and program products are presented that perform the following: allocating a set of sounding reference signal resources in a sounding reference signal resource space to a plurality of user equipment using a portioning scheme, and signaling indications of the allocated set of sounding reference signal resources to the plurality of user equipment. The portioning scheme may be a load balancing, complete partitioning, or hybrid scheme. The selection of a portioning scheme may be based on load.
Claims22
A method comprising:
- allocating a set of sounding reference signal resources in a sounding reference signal resource space to a plurality of user equipment using a portioning scheme;
