Claims

A method for wireless communication in a user equipment (UE), comprising:
receiving control signaling indicating a truncation configuration for truncating one or more fields of an initial identification indicator, wherein said one or more fields of said initial identification indicator are a network capability identifier field and a UE a step including an identifier field ;
generating a truncated identity indicator for the UE according to the truncation configuration by removing one or more bits from the initial identity indicator;
and C. transmitting said truncation identification indicator to a base station.

identifying a number of least significant bits of one or more fields of the initial identification indicator based at least in part on the truncation configuration;
and generating the truncated identification indicator comprising the identified number of least significant bits of the one or more fields.

Generating the truncated identification indicator comprises:
removing the one or more bits from the initial identification indicator by removing some most significant bits from at least one of the one or more fields of the initial identification indicator according to the truncation configuration; removing, wherein removing some of the most significant bits produces one or more truncated fields;
2. The method of claim 1, further comprising concatenating the one or more truncated fields, wherein the truncation identifying indicator comprises the concatenated one or more truncated fields.

2. The truncated identification indicator of claim 1, wherein the truncated identification indicator comprises a concatenation of the one or more fields of the initial identification indicator, at least one of the one or more fields being truncated according to the truncation configuration. Method.

2. The method of claim 1, wherein each of said one or more fields of said initial identification indicator comprises a fixed number of bits.

Generating the truncated identification indicator comprises:
reducing the first of the one or more fields of the initial identification indicator based at least in part on the number of bits in the second of the one or more fields of the truncated identification indicator; 2. The method of claim 1, further comprising truncating.

2. The method of claim 1, wherein the one or more fields of the initial identification indicator comprise a network capability identifier field and a UE identifier field.

2. The method of claim 1, wherein the truncated identification indicator comprises a temporary mobile subscription identifier.

2. The method of claim 1, wherein the control signaling comprises dedicated control signaling or broadcast control signaling.

2. The method of claim 1, wherein the truncation identification indicator is a Radio Resource Control Connection Re-establishment message for Narrowband Internet of Things.

2. The method of claim 1, further comprising establishing a connection with the base station based at least in part on transmitting the truncation identification indicator.

receiving the control signaling comprises:
2. The method of claim 1, comprising receiving the control signaling from an access and mobility management function.

A method for wireless communication in a network comprising access and mobility management functions and base stations, comprising:
determining, by the access and mobility management function, a truncation configuration for truncating one or more fields of the initial identification indicator by removing one or more bits from the initial identification indicator, said truncation configuration based at least in part on the number of possible values stored in each of said one or more fields, wherein said one or more fields of said initial identification indicator are network capabilities; comprising an identifier field and a UE identifier field ;
sending, by the access and mobility management function, control signaling indicating the truncation configuration;
