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.

In various embodiments, other scheduled transmissions, i.e., other than random access signals, are scheduled for transmission on a set of allowed random access resources. In various embodiments, unscheduled other transmissions are transmitted on a set of allowed random access resources. Such scheduled or unscheduled transmissions include data, control and/or reference signal transmissions from devices, backhaul transmissions and fronthaul transmissions. In various embodiments, such transmissions are received (which could include received, processed, detected and/or decoded) by other TP(s) than the TP that performs random access signal detection on the set of allowed random access resources. Hence, the random access resources can be reused in network, improving the overall efficiency. This is sometimes called space division multiple access. In various embodiments, such transmissions are received (which could include received, processed, detected and/or decoded) by the same TP(s) that performs random access signal detection on the set of allowed random access resources. This could be achieved by using various forms of multiplexing of the transmissions, in various embodiments, for instance code multiplexing, spatial multiplexing using multiple receive antennas, etc. In this way, the random access resources can be further reused in the network.

Several benefits of the method in various embodiments are listed below. For example,

    • Detection Delay
