A user equipment (UE) is configured with a first configuration for reporting measurement feedback information according to a first reporting cycle using a first set of parameters, and a second configuration for reporting measurement feedback information according to a second reporting cycle using a second set of parameters. The UE switches between the first cycle and the second cycle for reporting for example CQI based on for example comparing a data or a channel measurement against a predefined threshold. In various embodiments the second configuration is fixed, or results in no CQI reporting, or is variable based on a previous cycle or CQI level, or is event-based. In another embodiment, the network commands the UE to switch. The end result is that control signalling overhead can be reduced when appropriate by reducing the number of CQI reports that are sent uplink.

Embodiments include a method by which a network equipment efficiently directs a device attempting a connection to a congested or limited-capacity portion of a network to another resource (e.g., cell, frequency, and/or RAT) where the attempt is more likely to be successful. This method utilizes a connection reject message that comprises a small amount of information pointing to information broadcast in system information (SI) messages. The reject message may be used with existing or, alternately, enhanced SI messages comprising tags that resolve the pointer information in the reject message. Embodiments also include methods by which a device redirects to a resource based on the information contained in the reject and SI messages. Other embodiments include methods by which a device deprioritizes a resource during cell reselection based on information contained in the reject and SI messages. Embodiments include wireless communication devices, network equipment, or computer-readable media embodying these methods.

A serving cell sends to user equipments (UEs) indications of frequency bands supported by neighbor cells/frequencies, at least one individual neighbor cell/frequency supporting a plurality of frequency bands. The neighbor cells/frequencies are filtered by the UE to retain only those that are indicated to support a frequency band or frequency bands which are also supported by the UE. The sent indications comprise, for each respective neighbor cell/frequency, one absolute radio frequency channel number (ARFCN) associated with the respective neighbor cell/frequency and the frequency band or bands associated with the respective neighbor cell/frequency. Examples are given of various system information blocks for sending the frequency band indications to the UE. In one embodiment they are arranged in an information element IE having an entry for each of the neighbor cells/frequencies and a list of frequency bands for each entry.
