Abstract
According to some embodiments, a method for use in a wireless communication network includes a wireless device receiving, from a network, a configuration corresponding to a Physical Random Access Channel (PRACH). The wireless device receives, from the network via Radio Resource Control (RRC) signaling, a bitmap that provides an indication of time locations corresponding to synchronization signal (SS) blocks. The wireless device determines, based on the configuration and the bitmap, a time slot that does not overlap with the time locations to perform a PRACH transmission during the determined time slot.
Claims17
A method performed by a wireless device operating in an unpaired spectrum, the method comprising:
- receiving, from a network, a configuration corresponding to a Physical Random Access Channel (PRACH);
- receiving, from the network via Radio Resource Control (RRC) signaling, a bitmap that provides an indication of time locations corresponding to synchronization signal (SS) blocks of an SS burst set transmitted by the network;
- restricting at least one PRACH transmission during at least one of the time locations;
- determining, based on the configuration and the bitmap, a time slot between the time locations that does not overlap with the time locations;
- and
- performing a PRACH transmission during the time slot.
A non-transitory computer readable medium having stored thereon computer readable program code executable to cause a wireless device to perform operations comprising:
- receiving, from a network, a configuration corresponding to a Physical Random Access Channel (PRACH);
- receiving, from the network via Radio Resource Control (RRC) signaling, a bitmap that provides an indication of time locations corresponding to synchronization signal (SS) blocks of an SS burst set transmitted by the network;
- restricting at least one PRACH transmission during the time locations;
- determining, based on the configuration and the bitmap, a time slot between the time locations that does not overlap with the time locations;
- and
- performing a PRACH transmission during the time slot.
A system comprising:
- a non-transitory memory;
- and
- processing circuitry coupled to the non-transitory memory and configured to read instructions from the non-transitory memory to cause the system to perform operations comprising:
- receiving, from a network, a configuration corresponding to a Physical Random Access Channel (PRACH);
- receiving, from the network via Radio Resource Control (RRC) signaling, a bitmap that provides an indication of time locations corresponding to synchronization signal (SS) blocks of an SS burst set transmitted by the network;
- restricting at least one PRACH transmission during the time locations;
- determining, based on the configuration and the bitmap, a time slot between the time locations that does not overlap with the time locations;
- and
- performing a PRACH transmission during the time slot.
