Uplink-based cell selection

An apparatus for wireless communication by a user equipment (UE), comprising:

• means for receiving reference signals from one or more transmission reception points (TRPs) in a wireless communications network;
• means for pre-selecting, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service;
• means for transmitting an uplink (UL) signal to the first TRP;
• means for receiving, from the first TRP, feedback comprising information about the UL signal;
• and
• means for determining, based at least in part on the feedback, without a handover command message, at least one of:
• a new TRP to camp on in an operating state in which a context of the UE is not stored in the wireless communications network;
• or
• a new TRP to camp on if the context of the UE is stored in the wireless communications network.

A method for wireless communication by a user equipment (UE), comprising:

• receiving reference signals from one or more transmission reception points (TRPs) in a wireless communications network;
• pre-selecting, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service;
• transmitting an uplink (UL) signal to the first TRP;
• receiving, from the first TRP, feedback comprising information about the UL signal;
• and
• determining, based at least in part on the feedback, to select the first TRP from which to receive the wireless service,
• wherein receiving the feedback comprises receiving the feedback on a channel specifically designated for transmission and reception of feedback for UL signals;
• wherein the channel is scrambled with a TRP-specific identifier;
• wherein the reference signal received from the first TRP comprises the TRP-specific identifier for the first TRP;
• and
• further comprising decoding the channel using the TRP-specific identifier for the first TRP to receive the feedback.

An apparatus for wireless communication by a user equipment (UE), comprising:

• at least one processor configured to:
• receive reference signals from one or more transmission reception points (TRPs) in a wireless communications network, the reference signals including TRP-specific identifiers for the one or more TRPs;
• pre-select, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service;
• transmit an uplink (UL) signal to the first TRP;
• receive, from the first TRP, on a channel specifically designated for transmission and reception of feedback for UL signals, feedback comprising information about the UL signal;
• decode the channel using the TRP-specific identifier for the first TRP;
• and
• determine, based at least in part on the feedback, to select the first TRP from which to receive the wireless service;
• and
• a memory coupled with the at least one processor.

A non-transitory computer-readable medium for wireless communication by a user equipment (UE), comprising instructions that, when executed by at least one processor, cause the at least one processor to:

• receive reference signals from one or more transmission reception points (TRPs) in a wireless communications network, wherein each reference signals includes a TRP-specific identifier;
• pre-select, based on the received reference signals, a first TRP, of the one or more TRPs, from which to receive wireless service;
• transmit an uplink (UL) signal to the first TRP;
• receive, from the first TRP, on a channel specifically designated for transmission and reception of feedback for UL signals, feedback comprising information about the UL signal;
• means to descramble the channel using a TRP-specific identifier of the first TRP to access the feedback;
• and
• determine, based at least in part on the feedback, to select the first TRP from which to receive the wireless service.
