Methods and apparatus for wireless communication in a wireless communication network include maintaining a Public Land Mobile Network (PLMN) list and receiving an information request from a network, wherein the information request is associated with configuration parameters associated with the PLMN list. Aspects of the methods and apparatus configuring the UE based on the configuration parameters associated with the PLMN list. Aspects also include replying to the network that the UE is configured with the configuration parameters associated with the PLMN list.

Apparatus and method for signaling network capabilities for a wireless device

Aspects disclosed herein relate to determining frequencies for measuring cells in reselection. A set of frequencies over which to measure cells for reselection can be prioritized, wherein one or more first frequencies in the set of frequencies correspond to frequencies of previously visited closed subscriber group (CSG) cells, multimedia broadcast multicast services (MBMS) frequencies, etc. A command to deprioritize one or more second frequencies for reselection can be received, and it can be determined whether to deprioritize the one or more second frequencies in the prioritized set of frequencies based at least in part on the command. One or more cells can be measured over the prioritized set of frequencies based at least in part on respective priorities of the set of frequencies and may be evaluated for reselection.

Techniques for resolving conflicting rules in measuring cells for reselection

Methods, systems, and devices are described for recovery from a connection disruption of a user equipment (UE) operating in a multi-carrier mode. The UE may establish a first connection with a primary cell and a second connection with a secondary cell while operating in the multi-carrier mode. A determination may be made that a disruption in the connection with the primary cell has occurred, and the UE may perform a connection reestablishment procedure to attempt to reestablish communications. The connection reestablishment routine may prioritize the secondary cell ahead of one or more other cells for attempting to reestablish communications. The prioritization may be based at least in part on the establishment of the second connection in the multi-carrier mode.

Fast recovery mechanisms for multi-carrier enabled UEs

Methods and apparatus for enhanced radio resource control (RRC) reestablishment in a communication system include addressing repeated radio link failures (RLFs). For example, the methods and apparatus include incrementing a counter value associated with a first cell based on a detection of a RLF by a user equipment (UE) in a RRC connected state with the first cell. The methods and apparatus further include determining that the counter value meets or exceeds a first barring threshold value within a cell barring evaluation time duration. Additionally, the methods and apparatus include prohibiting the UE from performing an RRC reestablishment procedure with the first cell for a first barring time duration.

Addressing radio link failures in wireless communication systems

Methods, systems, and devices are described for reducing congestion in a wireless communications system. A second connection failure is detected, and a difference between a timestamp of the second connection failure and a timestamp of a first connection failure is calculated. Upon determining that the difference satisfies a first time threshold, information relating to one or more previous connection failures is cleared. A time period is identified. A number of connection failures from a cell that occur during the time period is identified. A determination is made as to whether the number of connection failures satisfies a threshold. Upon determining that the number of connection failures satisfies the threshold, a future connection request may be withheld for a time period.
