Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first physical broadcast channel (PBCH) communication on a channel. The UE may decode the first PBCH communication as a decoded PBCH payload. The UE may reencode the decoded PBCH payload as a first pilot signal. The UE may receive a first data communication with first data. The UE may correct the channel for the first data based on the first pilot signal. The UE may decode the first data. Numerous other aspects are described.
Claims30
A method of wireless communication performed by an apparatus of a user equipment (UE), comprising:
- receiving a first physical broadcast channel (PBCH) communication, carrying system information, on a channel;
- decoding the first PBCH communication as a decoded PBCH payload;
- reencoding the decoded PBCH payload as a first pilot signal used for channel estimation;
- receiving, on the channel, a first data communication with first data;
- correcting the channel for the first data based on the first pilot signal;
- and
- decoding the first data.
An apparatus of a user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors coupled to the memory, the memory comprising instructions executable by the one or more processors to cause the UE to:
- receive a first physical broadcast channel (PBCH) communication, carrying system information, on a channel;
- decode the first PBCH communication as a decoded PBCH payload;
- reencode the decoded PBCH payload as a first pilot signal used for channel estimation;
- receive, on the channel, a first data communication with first data;
- correct the channel for the first data based on the first pilot signal;
- and
- decode the first data.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive a first physical broadcast channel (PBCH) communication, carrying system information, on a channel;
- decode the first PBCH communication as a decoded PBCH payload;
- reencode the decoded PBCH payload as a first pilot signal used for channel estimation;
- receive, on the channel, a first data communication with first data;
- correct the channel for the first data based on the first pilot signal;
- and
- decode the first data.
An apparatus for wireless communication, comprising:
- means for receiving a first physical broadcast channel (PBCH) communication, carrying system information, on a channel;
- means for decoding the first PBCH communication as a decoded PBCH payload;
- means for reencoding the decoded PBCH payload as a first pilot signal used for channel estimation;
- means for receiving, on the channel, a first data communication with first data;
- means for correcting the channel for the first data based on the first pilot signal;
- and
- means for decoding the first data.
