Discuss Huawei H35-480_V3.0 Exam Topic 3 Question 76

Which of the following statements about the NR slot structure are correct? (Choose All that Apply)

ADownlink slots can only be used to transmit downlink data.

BDownlink self-contained slots can be used to transmit uplink data and SRSs.

CThe number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.

DThe symbols in a slot can be classified as downlink, uplink, or flexible.

Suggested Answer: A, B, D

1. NR downlink slots are used to transmit downlink data and control information, such as channel state information (CSI) and downlink control information (DCI). B. Downlink self-contained slots are also called as 'Downlink Shared Channels (DL-SCH) slots', they can be used to transmit downlink data, but also can be used to transmit uplink control information (UCI) and sounding reference signals (SRS) in the downlink direction.

2. The symbols in a slot can be classified as downlink, uplink, or flexible, meaning that the symbols can be used to transmit data in either direction, or to transmit control information.

It's worth noting that the NR slot structure is designed to be flexible and efficient, it allows for a variable slot duration and a variable number of symbols, depending on the subcarrier spacing and the number of resource blocks used. This flexibility is intended to support a wide range of services and traffic types.

I think D is the best choice. Flexibility is key in NR.

I feel confused about A and B. Need to review more.

D seems correct. Slots can be flexible in usage.

C is misleading. The number of symbols can change with spacing.

Lai 2 months ago

I agree, B is tricky. It can transmit uplink data.

Carey 2 months ago

I think A is definitely wrong. Downlink slots can do more.

Not sure about A), seems too strict to me.

C) is true, 14 symbols is fixed across the board.

Macy 3 months ago

D seems plausible because I recall that slots can have different classifications, but I’m not completely confident about the specifics.

Xuan 3 months ago

I’m a bit confused about C; I thought the number of symbols could change based on the subcarrier spacing, but I need to double-check that.

Nieves 3 months ago

I practiced a similar question where we discussed self-contained slots, and I feel like B could be true since they might allow for uplink data too.

Garry 4 months ago

I think I remember that downlink slots are primarily for downlink data, so A might be correct, but I'm not entirely sure.
