The phrase "allow a secondary" is correct and usable in written English.
It can be used in contexts where you are permitting or enabling a secondary option, choice, or entity to be involved or considered.
Example: "The system is designed to allow a secondary user to access the main features without compromising security."
Alternatives: "permit a secondary" or "enable a secondary".
So, more efficient resource allocation ways are urgently needed and a key spectrum allocation solution is to allow a secondary user (SU) to simultaneously share a licensed spectrum with the primary link as long as the interference from the secondary transmission does not go beyond the tolerable threshold of the primary link [2].
Within each clone, cell number increases enough to allow a secondary improving mutation.
The number of cells in the colony may allow a secondary mutation with no increase in mutation rate.
Notifications allow Dyn to notify secondary servers of changes and transfer allows a secondary server to ask Dyn for a complete copy of the zone.
A piggyback toric IOL can be implanted in an obliquely crossed style that allows a secondary toric IOL to correct astigmatism induced by long-term toric IOL rotation.
When a primary user is detected, spectrum mobility allows a secondary user to leave its channel, and to access an idle band where it can re-establish the communication link.
Since RAP-MAC allows a secondary sender to use different transmission powers with certain probabilities, it is sufficient that the maximum permissible power P max ( i ) which is used with probability Pr[SU-TX] = p satisfies the condition in (19).
In addition, we have isolated and enriched a trace methionine-oxidized variant of the monoclonal antibody allowing a secondary means of identification of this variant while providing sufficient enrichment for further analysis, stability tests and potency determination.
Researchers over the years have proposed dynamic spectrum access (DSA) techniques to utilize the spectrum more efficiently by allowing a secondary system (for example a WSN) to co-exist in the same frequency band as a primary system and opportunistically access the licensed bands [9 11].
The parameter α is assumed as 0 < α < 1. Presuming that the government distributes permits uniformly across firms and then allows a secondary market in those permits, then those firms maximize their profits at each date, taking the wage rate w t and the price of permit τ t as given.
In Undercover, we allow a group of secondary users, each with a single antenna, to collaborate together and transmit in the regions of primary users activity.
