Measurement-based random access configuration
摘要
說(shuō)明書(shū)
Various embodiments above include the use of thresholds. In some embodiments, a threshold value is explicitly defined in a standard. In some embodiments, a threshold value may be configured in broadcasted system information. In some embodiments, a threshold value was configured specifically for the device in an earlier connection to the network, for example, in an embodiment where the initial access in this disclosure is part of a handover procedure, and the device was connected to the earlier connection before the handover. In some embodiments where a device is capable of multiple simultaneous connections, such as dual connectivity in LTE or multi-connectivity in future systems, a threshold value is configured through an already present connection. An already present connection is on the same carrier (i.e. frequency band) as the carrier where the initial access.
The disclosure also provides multiple embodiments with the one or more measurements RS(s) (with measurement results that are within a certain range of the highest measurement result) being mapped to multiple sets of allowed random access resources. In some embodiments, each of those measurement RS's are mapped to a set of allowed random access resources. In some embodiments, the one or more measurement RS(s) are jointly mapped to multiple sets of allowed random access resources.
The disclosure also covers the embodiments described above, but in which the lowest measurement results are used instead of the highest.
In various embodiments, other factors are taken into account in the mapping, in addition to measurements results, as listed in various embodiments above. For example,
