Samsung patents faster 5G antenna switching for mobile devices
Samsung describes a method for mobile devices to switch antennas more quickly when connecting to a 5G network. The device tells the network which antenna settings it supports, and the network sends a signal to start testing those antennas after a specific, pre-agreed delay.
In the filing’s own words
Methods and apparatuses for early sounding referenced signal (SRS) triggering. a method of operating a user equipment (UE) is provided. The method includes receiving configuration information for a list of sounding reference signal (SRS) resource sets for antenna switching and a list of timing offsets, initiating a Type-1 random access (RA) procedure to transition from an idle state to a connected state, and transmitting, in a message 3 (msg3) of the RA procedure, information indicating an antenna switching capability. The method further includes receiving a message to trigger transmission of an SRS resource set from the list of SRS resource sets and transmitting the SRS resource set at or after the timing offset. The SRS resource set corresponds to the antenna switching capability. The message indicates a timing offset from the list of timing offsets. The timing offset is relative to a slot that includes the message.
What exactly they claim (claim 1)
1. A user equipment (UE) comprising: a transceiver configured to receive configuration information for: a list of sounding reference signal (SRS) resource sets for antenna switching, and a list of timing offsets; and a processor operably coupled to the transceiver, the processor configured to initiate a Type-1 random access (RA) procedure to transition from an idle state to a connected state, wherein the transceiver is further configured to: transmit, in a message 3 (msg3) of the RA procedure, information indicating an antenna switching capability, receive a message to trigger transmission of a SRS resource set from the list of SRS resource sets, wherein: the SRS resource set corresponds to the antenna switching capability, the message indicates a timing offset from the list of timing offsets, and the timing offset is relative to a slot that includes the message, and transmit the SRS resource set at or after the timing offset.
