Table 10.1.48-1: +CBPI action command syntax

Command	Possible Response(s)
+CBPI[=<uplink_bandwidth_preference>[,<downlink_bandwidth_preference>]]	+CME ERROR: <err>
+CBPI=?	+CBPI: (list of supported <uplink_bandwidth_preference>s),(list of supported <downlink_bandwidth_preference>s)

Description

This command indicates to the MT the frequency bandwidth preference for uplink or for downlink.

For BL UEs or for UEs operating in coverage enhancement mode. If further conditions defined in 3GPP TS 36.331 [86] are met, this may cause transmission to the network of a UEAssistanceInformation message with bw-Preference set to <uplink_bandwidth_preference> and <downlink_bandwidth_preference>.

Test command returns the values supported as compound values.

Refer clause 9.2 for possible <err> values.

Defined values

<uplink_bandwidth_preference>: integer type; indicates the TE’s preference on configuration on maximum Physical Uplink Shared Channel bandwidth.

0 no preference indicated by the TE

1 CE mode usage in 1.4MHz

2 CE mode usage in 5MHz

<downlink_bandwidth_preference>: integer type; indicates the TE’s preference on configuration on maximum Physical Downlink Shared Channel bandwidth.

0 no preference indicated by the TE

1 CE mode usage in 1.4MHz

2 CE mode usage in 5MHz

3 CE mode usage in 20MHz (normal coverage)

Implementation

Optional.
