Q101.
Which among the following is not a step in spectrum sharing?

a.

Spectrum sensing

b.

Spectrum mobility

c.

Spectrum access

d.

Spectrum management

Discuss
Answer: (d).Spectrum management Explanation:Spectrum sharing process is integrated with spectrum sensing, spectrum allocation, spectrum access, handshake mechanism, and spectrum mobility. Thus the selection of best available spectrum, prevention of collision due to the overlapping portion of the spectrum, and seamless connection for communication regardless of the location of the user involves spectrum sharing.
Q102.
Which among the following layer operation is similar to that of spectrum sharing?

a.

Physical

b.

Data-link

c.

Network

d.

Transport

Discuss
Answer: (b).Data-link Explanation:The data link layer particularly the MAC portion is responsible for collision avoidance. Likewise, spectrum sharing is responsible for avoiding collision between licensed and unlicensed users of the licensed spectrum band as well as for avoiding collision among xG users in the unlicensed band.
Q103.
Which among the following is a constraint observed in hardware constrained MAC protocol for cognitive radio networks?

a.

Hidden terminal problem

b.

Synchronization among xG users

c.

Synchronization between xG user and primary user

d.

Shadowing uncertainty

Discuss
Answer: (a).Hidden terminal problem Explanation:Sensing in a limited geographic area with a fixed bandwidth limit on secondary users is a challenge for hardware constrained MAC protocol. Thus hidden terminal problem is observed in the hardware constrained MAC protocol. The demand for synchronization among xG users is a problem of concern for cognitive MAC protocol.
Q104.
Transmitter-receiver handshake does not involve any central entity such as the primary base-station.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:The transmitter-receiver handshake conveys the selected spectrum for communication to the receiver. This protocol is not limited between a transmitter and a receiver and may also include external entities such as a primary base-station especially in methods such as cooperative spectrum sharing.
Q105.
What is the basic unit of channel allocation?

a.

P frame

b.

Q frame

c.

R frame

d.

S frame

Discuss
Answer: (b).Q frame Explanation:A Q frame is the basic unit of channel allocation. When a Q frame is allocated by a base-station, the base-station can use its control and data channels for coordination and data communication between the users.
Q106.
What is the full form of DQSDR?

a.

Dynamic Quality of Service Distributed Reservation scheme

b.

Distributed Quality of Service Dynamic Reservation scheme

c.

Dynamic Quality of Service Distributed Resource scheme

d.

Distributed Quality of Service Dynamic Resource scheme

Discuss
Answer: (b).Distributed Quality of Service Dynamic Reservation scheme Explanation:In Distributed Quality of Service Dynamic Reservation scheme, a base-station competes with an interfering base-station to allocate a spectrum band that satisfies the quality of service requirements of the user application.
Q107.
What is the use of a common control channel?

a.

Transmission coordination

b.

Spectrum allocation

c.

Spectrum analysis

d.

Time of arrival synchronization

Discuss
Answer: (a).Transmission coordination Explanation:The common control channel is used to exchange spectrum information among xG users and also support transmission coordination. The common control channel is mainly classified as an in-band channel or as an out-of-band channel.
Q108.
Which among the following is a common control channel used by a radio to gain access to a system?

a.

Paging Channel

b.

Random Access Channel

c.

Access Grant Control Channel

d.

Cell Broadcast Channel

Discuss
Answer: (b).Random Access Channel Explanation:Common control channel transfers control information from a radio to a base-station. Random access channel is required to gain access to a system. It is invoked when the radio starts a call or replies to a page.
Q109.
Which among the following may be employed to select a common control channel in cooperative intra-network spectrum sharing?

a.

Regression

b.

Munging

c.

K-nearest neighbour

d.

Clustering

Discuss
Answer: (d).Clustering Explanation:In a local group, each node shares several channels with its neighbours. Each group may employ a clustering algorithm to select a common channel for communication. Distributed sensing and spectrum sharing is also carried out in the common channel.
Q110.
What is a local bargaining group?

a.

Local bargaining group is a set of users with a threshold limit guaranteed to provide minimum spectrum allocation to each user

b.

Local bargaining group is a set of users with a threshold limit that determines one particular user to operate the spectrum band

c.

Local bargaining group is a set of users with a threshold limit on the number of transmissions permissible over a certain period

d.

Local bargaining group is a set of users that compete for access of the spectrum band

Discuss
Answer: (a).Local bargaining group is a set of users with a threshold limit guaranteed to provide minimum spectrum allocation to each user Explanation:Local bargaining scheme is a cooperative intra-network sharing technique. It improves spectrum utilization and ensures fairness in the allocation of spectrum. It involves creating a local bargaining group with a threshold limit that ensures minimum allocation of spectrum to each user of the group.
