Abstract
The present application relates to acquiring system information. In an example, a network can transmit instances of a same system information on multiple SSB beams. A UE can select a set of the SSB beams for system information acquisition. Soft decoding information, such as LLR, from the decoding of the instances received on the selected SSB beams is combined to decode and acquire the system information.
Claims20
A user equipment (UE) comprising:
- one or more processors;
- and
- one or more memories storing instructions that, upon execution by the one or more processors, configure the UE to:
- receive, from a network during a system information (SI) window, a plurality of SI instances of system information, wherein the SI window is a time duration during which the network transmits the plurality of SI instances, and wherein at least one SI instance is transmitted per beam of a plurality of beams;
- decode a first SI instance of the plurality of SI instances, the first SI instance received over a first beam of the plurality of beams;
- decode a second SI instance of the plurality of SI instances, the second SI instance received over a second beam of the plurality of beams;
- and
- acquire the system information based on the decoding of the first SI instance and the decoding of the second SI instance.
A method implemented by a user equipment (UE), the method comprising:
- receiving, from a network during a system information (SI) window, a plurality of SI instances of system information, wherein the SI window is a time duration during which the network transmits the plurality of SI instances, and wherein at least one SI instance is transmitted per beam of a plurality of beams;
- decoding a first SI instance of the plurality of SI instances, the first SI instance received over a first beam of the plurality of beams;
- decoding a second SI instance of the plurality of SI instances, the second SI instance received over a second beam of the plurality of beams;
- and
- acquiring the system information based on the decoding of the first SI instance and the decoding of the second SI instance.
One or more computer-readable storage media storing instructions that, upon execution on a user equipment (UE), cause the UE to perform operations comprising:
- receiving, from a network during a system information (SI) window, a plurality of SI instances of system information, wherein the SI window is a time duration during which the network transmits the plurality of SI instances, and wherein at least one SI instance is transmitted per beam of a plurality of beams;
- decoding a first SI instance of the plurality of SI instances, the first SI instance received over a first beam of the plurality of beams;
- decoding a second SI instance of the plurality of SI instances, the second SI instance received over a second beam of the plurality of beams;
- and
- acquiring the system information based on the decoding of the first SI instance and the decoding of the second SI instance.
