摘要
A method includes: receiving one or more synchronization signals; deriving a synchronization reference from the one or more synchronization signals; receiving a plurality of reference signals; based on the derived synchronization reference, performing a plurality of measurements on the plurality of reference signals; based on the plurality of measurements, selecting a plurality of random access resources; and selecting a random access resource from the plurality of random access resources for transmitting a random access signal to at least one of the one or more TP's.

- By immediately learning that a TPs has a good link to the device, TP sets for CoMP operation can be set up immediately. The set up could involve setting up backhaul links, resource coordination, security etc., in various embodiments. In some state of the art systems according to other embodiments, a CoMP set can be set up only after individual TPs have performed measurements on the detected random access signal, followed by a collection of the results at a node to perform a centralized CoMP set decision, or followed by a distributed CoMP set decision involving inter-TP information exchange. Both these approaches involve further time delays, which are avoided by using the method in this disclosure. This can improve the communication latency experienced by latency sensitive services and applications.
