Abstract
In one aspect, network node operates in a wireless communications network that includes two or more beam-based transmission points (30), where each of the two or more beam-based transmission points transmits synchronization signals corresponding to beams transmitted by the respective transmission point. The network node configures the two or more beam-based transmission points to use non-conflicting radio resources for their respective transmissions of synchronization signals.

1-51. (canceled)
A method of operation by a beam-based transmission point in a wireless communication network comprising two or more beam-based transmission points, the method comprising:
- selecting radio resources in dependence on an assigned identifier or other configured value, wherein the transmission point derives a time shift and/or frequency shift as a function of the assigned identifier or other configured value, wherein the time shift and/or frequency shift control the radio resources selected by the transmission point for transmission of the synchronization signals;
- and
- transmitting synchronization signals using the selected radio resources, the synchronization signals being transmitted in association with two or more beams transmitted by the transmission point.
A method of operation in a wireless device configured for operation in a wireless communication network comprising two or more beam-based transmission points, wherein each of the two or more beam-based transmission points transmits synchronization signals corresponding to beams transmitted by the respective transmission point, the method comprising:
- receiving information from the wireless communications network indicating a set of synchronization signals to use as synchronization sources, wherein each of the two or more beam-based transmission points is configured to select the radio resources used for synchronization signal transmission in dependence on a value of an assigned identifier, and wherein the radio resources selected by each of the two or more transmission points for transmission of the synchronization signals are derived by a time shift and/or frequency shift as a function of the assigned identifier;
- and
- maintaining synchronization with the wireless communication network based on detecting any one or more of the synchronization signals in the set of synchronization signals.
A beam-based transmission point in a wireless communication network comprising two or more beam-based transmission points, the beam-based transmission point comprising:
