Abstract: An efficient random access procedure is provided for reduced control overhead of connections in random access systems. A base station transmits one or more synchronization signal (SS) blocks. A UE detects and determines a preferred SS block. The UE transmits multiple random access signals (e.g., PRACH signals) in a RACH occasion. Each PRACH signal is transmitted on a different beam and includes a RACH preamble. The base station receives one or more of the PRACH signals. The RACH occasion and optionally the RACH preamble identify the preferred SS block. The base station determines a preferred PRACH signal. The base station sends a RAR to the UE using the transmit beam of the preferred SS block. The RAR indicates the preferred PRACH signal and an uplink resource allocation. The UE receives the RAR and transmits a message using the transmit beam of the preferred PRACH signal and the uplink resource allocation.

Abstract: A mechanism is disclosed for implementing conditional commands carried by network data packets. A data flow including a data packet is received. The data packet includes a conditional command. A condition and a command are obtained from the conditional command. The mechanism determines that the condition is satisfied. Based on the determination that the condition is satisfied, the command is executed to alter handling of the data flow, alter handling of the data packet, or alter a context for the data flow.

Abstract: A network device employs a transmitter configured to transmit a registration request to a software defined network (SDN) controller. The network device employs a receiver to receive a reply from the SDN controller. The reply indicates a plurality of provider edge (PE) devices coupled to a carrier network. The network device employs a processor to cause the transmitter and receiver to establish a plurality of asymmetric connections to a virtual private network (VPN) operating over a wide area network (WAN) via the PE devices.

Abstract: Branch prediction techniques are described that can improve the performance of pipelined microprocessors. A microprocessor with a hierarchical branch prediction structure is presented. The hierarchy of branch predictors includes: a multi-cycle predictor that provides very accurate branch predictions, but with a latency of multiple cycles; a small and simple branch predictor that can provide branch predictions for a sub-set of instructions with zero-cycle latency; and a fast, intermediate level branch predictor that provides relatively accurate branch prediction, while still having a low, but non-zero instruction prediction latency of only one cycle, for example. To improve operation, the higher accuracy, higher latency branch direction predictor and the fast, lower latency branch direction predictor can share a common target predictor.

Abstract: User equipments can achieve quick channel synchronization when establishing a connection to base stations transitioning from a sleep mode to an active mode by using discovery resource signal (DRS) processing results and cell reference signal (CRS) processing results to establish channel synchronization with a CRS antenna port. More specifically, the user equipment may be notified that the CRS antenna port and DRS antenna port are quasi-co-located (QCL), and then use DRS processing results in conjunction with CRS processing results to obtain faster channel synchronization with a CRS antenna port. This may be particularly beneficial when the target BS is transitioned from a sleep mode to an active mode in order to accept a handover of the user equipment.

Abstract: The disclosure relates to a base station configuring component carriers to user equipment (UE). The base station determines one or more component carriers to configure based on the UE carrier aggregation capability and sends a first configuration signaling to configure the UE with the component carriers in one or more component carrier sets. The base station configures each of the component carrier sets with a first common parameters and operations set and sends a second configuration signaling to configure the component carrier sets of the UE with the first common parameters and operations set. The base station then sends a third configuration signaling to configure each of the component carriers in the UE with a second parameters and operations set.

Abstract: A method for using metadata in an Internet Protocol (IP) packet is provided. A first processor at a first node sets a dedicated field of the IP packet to a predetermined value to indicate that metadata is present in the IP packet, and adds metadata to the IP packet by inserting the metadata between an original transport header of the IP packet and an original packet payload of the IP packet. A second processor at a second node receives the IP packet from the first node, reads the dedicated field to identify the predetermined value indicating that metadata is present in the IP packet, and identifies the metadata in the IP packet based on the predetermined value.

Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.
