Intra-frequency searching in the presence of frequency gaps
First Claim
1. An apparatus, comprising:
- a search scheduler for scheduling a search and for generating a frequency switch blocking signal; and
a frequency controller for generating frequency switch commands, receiving the frequency switch blocking signal, and suppressing the generation of frequency switch commands when the frequency switch blocking signal is asserted.

Abstract
Techniques for intra-frequency searching in the presence of frequency gaps are disclosed. In one embodiment, a search is scheduled and frequency switches are suppressed during the scheduled search. In another embodiment, a search is scheduled in between anticipated frequency gaps. In yet another embodiment, a timer is deployed, the expiration of which indicates a search is to be scheduled. In yet another embodiment, a timer is deployed, the expiration of which indicates a search is to be scheduled and frequency switches are suppressed during the scheduled search. Various other embodiments are also presented. Benefits include allowing prescribed levels of intra-frequency and inter-frequency search to be performed which allows for improved base station selection and therefore improved performance and system capacity.

13. A first Integrated Circuit (IC), responsive to a frequency switch signal generated in a second IC, the second IC comprising:
-
a search scheduler for scheduling a search and for generating a frequency switch blocking signal; and
a frequency controller for generating a frequency switch signal comprising frequency switch commands, receiving the frequency switch blocking signal, and suppressing the generation of frequency switch commands when the frequency switch blocking signal is asserted, the first IC comprising;
a frequency synthesizer to receive the frequency switch signal from the second IC and to generate an output signal, the frequency of the output signal changing from a first frequency to a second frequency in response to the frequency switch signal.
