Indicates the long DRX cycle and DRX start offset values to run onDurationTimer in DRX mode in normal status. The unit of

the long DRX cycle is a sub-frame. If the short DRX-Cycle is set to a value, this parameter is set to a multiple of the short DRX-

Cycle. The DRX start offset is set to an integer.

The Recommendation value is ci_sf160_chosen.

DRX

SHORT_DRXCYCLE_NORMAL

Indicates the short DRX cycle to run onDurationTimer in DRX mode in normal status.

The Recommendation value is ci_sf80_chosen.

It is optional to use Short DRX cycle after the expiration of drx-InactivityTimer. The purpose of using Short DRX cycle is

because in general, the probability of further activity is greater during the time window immediately after any previous activity.

DRX

ON_DURATION_TIMER_NORMAL

Indicates the timer to monitor PDCCH in DRX mode in normal status. (5.7 in TS 36.321) Value in number of PDCCH sub-

frames: psf1 for 1 PDCCH subframe, psf2 for 2 PDCCH sub-frames and so on (6.3.2 in TS 36.331)

The Recommendation value is ci_onDurationTimer_psf10

drx-onDurationTimer defines the periodically occurred time period in each DRX cycle, during which UE needs to monitor

DRX

DRX_INACTIVITY_TIMER_NORMAL

Indicates the length of the DRX Inactivity Timer, which is to monitor PDCCH in DRX mode in normal status. (5.7 in TS 36.321)

Value in number of PDCCH sub-frames: psf1 for 1 PDCCH subframe, psf2 for 2 PDCCH sub-frames and so on (6.3.2 in TS

36.331).

The Recommendation value is ci_drx_InactivityTimer_psf100

DRX

DRX_RETRANSMISSION_TIMER_NORMAL

Indicates the length of the DRX retransmission Timer, which is used to monitor PDCCH in DRX mode in normal status.

The Recommendation value is ci_drx_RetransmissionTimer_sf16

For DL retransmission, the possible retransmission occurs always after the expiration of HARQ RTT timer. Therefore, UE only

needs to monitor the PDCCH for retransmission after the expiration of HARQ RTT timer.

DRX

BETA

Channel quality weight in PF scheduler. The larger beta is, the better channel efficiency is. It is the parameter to control DL PF

scheduling and can be different from that for UL one.

More the channel quality weight, users at cell center with good channel quality will be prioritized over users at cell edge with

bad channel quality.

SCHEDULING

GAMMA

Delay weight in scheduling metric. User with lager scheduling delay will be prioritized. The larger gamma is, the smaller

scheduling delay is. However, if it is very high, system capacity can be decreased because scheduler considers delay

excessively. It is the parameter to control DL PF scheduling and can be different from that for UL one.

The Recommendation value is 4.

PHICH_DURATION

The PHICH duration set in accordance with Table 6.9.3-1 of TS 36.211. It sets the lower limit of a control region size that is

passed to PCFICH.

The change can be performed as the two ways:

1) Change the FORCED_MODE value from False to True. And Change the parameter value.

ACK-NAK

PHICH_RESOURCE

The parameter used to calculate the number of PHICH groups. With the larger value, the number of PHICH groups is

increased, while control region for CCE is decreased.

The change can be performed as the two ways:1) Change the FORCED_MODE value from False to True. And Change the parameter value.

ACK-NAK

ZERO_CORREL_ZONE_CONFIGThe zero correlation zone used to create a random preamble.

Be sure to refer to the SON Algorithm for changing this parameter because it affects the whole system. RACH

SPS_ACK_USAGE

CYCLIC_SHIFT

The n (1)_DMRS (Demodulation reference signal) value is cell-specific . The cyclic shift value of the PUSCH demodulation

reference signal is determined by both n(1)_DMRS value set by this parameter and the n (2)_DMRS value assigned in DCI

format 0. The reference signal sequence is defined by the cyclic shift of a Zadoff-Chu base sequence.

The change should be performed as follows:

RA_RESPONSE_WINDOW_SIZE

The period of time during which UE waits for RA Response. If the UE does not receive RA Response within this period of time,

it retransmits the preamble. RACH
