Abstract: In one embodiment, an apparatus includes a memory comprising instructions and a processor in communications with the memory. The processor is configured to execute the instructions to determine a reference signal received power of user equipment (UE). In response to determining that the reference signal received power is less than or equal to a threshold, it is determined that the UE supports sending a physical random access channel, receiving a random access response message, sending a random access response acknowledgment message, and receiving a contention resolution message. In response to determining that the reference signal received power is above the threshold, it is determined that the UE supports sending the physical random access channel, and receiving the contention resolution message, and it is determined that the UE does not support sending the random access response acknowledgment message and receiving the random access response message.

Abstract: The present invention discloses a method of transmitting an SSS (secondary synchronization signal), which is transmitted by a base station, in a wireless communication system. The method includes the steps of determining a first shift based on a first and a second cell identifiers for identifying a cell, and determining a second shift index based on the first cell identifier and transmitting the SSS using a first sequence which is generated based on the first shift index and a second sequence which is generated based on the second shift index. In this case, the first shift index can be determined as K times a value determined based on the first and second cell identifiers, where K is an integer equal to or greater than 3.

Abstract: Methods, systems, and devices for wireless communications are described that provide beam determination in beamformed wireless communications. A base station may transmit multiple repetitions of control information for a subsequent scheduled transmission. A user equipment (UE) may receive one of the multiple repetitions, determine the control information, and adjust beamforming parameters for the scheduled transmission. The UE may have a scheduling threshold that corresponds to a time needed for the UE to adjust beamforming parameters for the scheduled transmission, and the UE may identify the beamforming parameters for the scheduled transmission from any one of the multiple repetitions of control information, which may be transmitted using different downlink transmission beams, before or after the scheduling threshold, or combinations thereof.

Abstract: A method for UE route selection policy (URSP) rule matching is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offload to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. When the UE fails to find existing PDU session or setup new PDU session with any or the route selection descriptors of the non-default URSP rule, the UE moves to another non-default URSP rule, if any, and try the matching. If all non-default URSP rules cannot be matched with the application, then the UE tries the default URSP rule, which includes a match-all traffic descriptor.

Abstract: The system and methods of the various embodiments enable the efficient management and distribution of application filters or packet flow descriptions within a telecommunications network. A policy management system may be configured to receive a request message from a charging and enforcement (CaE) component, determine application identifiers for a data communication based on information included in the received request message, and determine policy rules. The policy management system may send a stimulus message that includes the determined application identifiers to a filter management system component so as to cause the filter management system to preemptively provision the charging and enforcement component with application filters. The policy management system may also send a response message that includes the determined policy rules to the CaE component.

Abstract: Wireless access points may automatically discover each other and establish connections based on accumulated credit values incremented via mutual exchanges of identifiers. A first access point may select a candidate access point for a potential connection, and may maintain a credit value for the selected candidate access point. The first access point may broadcast beacon messages, including an identification of the candidate access point and the credit value. Responsive to detecting a broadcast from the candidate access point including an identifier of the first access point, the first access point may increment the credit value. As each access point continues broadcasting beacon messages, it may increment its credit value for the other access point accordingly.
