Abstract
Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a user equipment (UE). In some examples, the method includes obtaining a key and using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission.
Claims28
A method for wireless communications by a user equipment (UE), comprising:
- obtaining a key;
- and
- using the key during physical layer signal processing of a physical uplink control channel (PUCCH) transmission having more than one symbol to provide security for the PUCCH transmission, wherein
- the physical layer signal processing comprises:
- converting information bits to a value I;
- selecting a sequence of length N from a sequence pool based on the value I;
- and
- mapping the sequence to N resource elements.
A method for wireless communications by a network entity, comprising:
- obtaining a key used to provide security for a physical uplink control channel (PUCCH) transmission having more than one symbol from a user equipment (UE);
- and
- using the key during physical layer signal processing of the PUCCH received from the UE, wherein
- the physical layer signal is received on N resource elements and processing comprises:
- demapping a sequence from the N resource elements;
- determining a value I associated with the sequence;
- and
- obtaining a set of information bits based on the value I.
