Measurement-based random access configuration
摘要
說明書
In various embodiments, a random access configuration includes an “unmapped” set of allowed random access resources, where “unmapped” means that the set is not selected based on a mapping from measurement result(s) on measurement RS(s), unlike the “mapped” sets of allowed random access resources described above. In various embodiments, devices may select a random access resource from an “unmapped” set of allowed random access resources if, for various reasons, it is more suitable than to select a random access resource from a “mapped” set. Such reasons may include, in various embodiments, that a measurement result based on measurement RS is not available or not reliable, for instance, due to:
-
- Requirements for low latency, such that a random access resource needs to be selected and random access signal transmitted before a measurement result is obtained.
- Measurement result is inaccurate.
- Device is moving at high speed so measurement results may be outdated
In various embodiments, an “unmapped” set of allowed random access resources is defined by an overall (union of) set of allowed random access resources and the “mapped” sets of allowed random access resources. The “unmapped” set is then the resources in the overall set that are not included in any of the “mapped” sets.
