B.8.1 Burst transmission model for one LAA SCell

This clause provides a description for burst transmission models for Frame structure type 3.

One burst is defined as downlink transmissions which occupy one or more consecutive subframes. The burst transmission format is determined according to the steps below:

1) Select the number of subframes randomly from a given set of the number of subframes with equal probability as the total length of burst transmission format. The length includes both occupied OFDM symbols and non-occupied OFDM symbols within the burst format. is given per test case.

2) If is equal to 1, the subframe is set as fully occupied, otherwise:

– For demodulation test, the starting position for the first subframe is randomly selected from OFDM symbol 0 and OFDM symbol 7 with equal probability. For CSI test, the starting position for the first subframe is OFDM symbol 0.

– The configuration of occupied OFDM symbols in the last subframe is randomly selected from configuration set . is given per test case.

A uniform random variable from [0, 1] is generated. If the random variable is less than p which is given per test case,

– If both the last subframe of previous burst and first subframe of new burst format are fully occupied, start burst transmission after deferring one subframe from the last subframe of previous burst. Otherwise, start burst transmission at the end of last subframe of previous burst.

– Otherwise, the burst transmission is muted and the muting duration is the same as the number of subframes for determined burst format.

Downlink Physical Channels

This annex specifies the downlink physical channels that are needed for setting a connection and channels that are needed during a connection.
