摘要： A method of transmitting a synchronization signal block, which is transmitted by a base station in a wireless communication system, is disclosed in the present invention. The method includes the steps of mapping a synchronization signal block including a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcasting channel) to a plurality of symbols, and transmitting the synchronization signal block mapped to a plurality of the symbols to a user equipment. In this case, in a symbol mapped the PSS, in a symbol mapped the SSS, and in a symbol mapped the PBCH, centers of subcarriers to which the PSS, the SSS, and the PBCH are mapped are the same and the number of subcarriers to which the PBCH is mapped is greater than the number of subcarriers to which the PSS and the SSS are mapped.

摘要： Efficient handling of control subbands in multiple component carrier (CC) configurations is discussed. A user equipment (UE) may begin monitoring one narrowband control subband within a wider band CC. At various times, the UE may receive a dynamic activation signal that triggers the UE to begin monitoring at least another control subband. Dependent on a type of traffic state the UE is operating, when currently involved in wideband operations, the UE may be triggered to monitor one or more UE-specific control subbands within the same slot in the wider band CC.

摘要： One embodiment provides a system that facilitates efficient communication based on a forwarding information base (FIB). The system receives, by an intermediate node, a first interest which includes a name and maximum interest information which indicates whether to forward a subsequent interest with a same name prefix as the first interest. In response to obtaining a first entry from a FIB based on the name for the first interest, the system adds to the first entry, for an outgoing interface corresponding to an arrival interface of the first interest, the maximum interest information included in the first interest as an interest limit for the first entry. In response to determining that the interest limit for the first entry is reached, the system refrains from forwarding the subsequent interest, thereby facilitating the intermediate node to manage traffic based on information in the forwarding information base provided by a content producer.

摘要： A method related to selecting a channel bandwidth may include partitioning the plurality of networks into a plurality (P) of local radio environments and identifying, for the P local radio environments, an available channel bandwidth set comprising a plurality of channel bandwidth values. The method may also relate to determining whether the plurality of channel bandwidth values provide a frequency reuse distance that is greater than a threshold frequency reuse distance, wherein the frequency reuse distance is estimated based at least on the pathloss measurement and, based on a determination that at least one of the plurality of channel bandwidth values provides the frequency reuse distance that is greater than the threshold frequency reuse distance, configuring a channel plan for the plurality of networks with a channel bandwidth value from the at least one of the plurality of channel bandwidth values.

摘要： A communication terminal has a wireless communication part and a control part. The control part sequentially switches a plurality of communication channels and discovers another communication terminal existing around the communication terminal itself. In the case of connecting to the other communication terminal found in the discovery, the control part determines which of the communication terminals transmits a connection request. In a case where the communication terminal itself does not transmit a connection request, the control part stops the discovery process and waists for reception of a connection request from the other communication terminal by using a given communication channel.

摘要： This application discloses a carrier indication method, user equipment, and a base station. The method includes: receiving, by user equipment, first information sent by a base station; if the user equipment is capable of transmitting uplink data and downlink data on a carrier, determining, by the user equipment according to the first information, a carrier used for transmitting first-type information; and transmitting, by the user equipment, the first-type information on the determined carrier, where the first-type information includes at least one of the following: uplink data, downlink data, and scheduling information. In this application, user equipment determines, according to first information sent by a base station, a carrier used for transmitting information, and therefore, can normally transmit information.

摘要： A network-on-chip flit transmission method and a network-on-chip flit transmission apparatus. The method includes: receiving a current flit including an operation ID Op ID, an operation type Op Type, and a payload; when determining that acceleration processing needs to be performed on the current flit, determining, according to the Op Type, whether the payload of the current flit affects an execution result of a destination node of the current flit, where the execution result is a result obtained by executing, by the destination node, a task corresponding to the Op ID; and forwarding the current flit to a next node if a determining result is yes; and discarding the current flit if a determining result is no. Therefore, not only a quantity of flits that need to be transmitted on a network-on-chip can be greatly reduced, but also a calculation amount of the destination node can be reduced.

The CPRI lane controller comprises a transaction counter, a symbol counter and a comparator. The transaction counter is provided for maintaining a current aggregated transactions' size, Sizetrans, representative of an accumulated size of DMA transactions performed by a DMA controller in response to symbols transferred on a CPRI link from or to the CPRI lane controller. The symbol counter is provided for maintaining a current aggregated expected symbols' size, Sizeexp, representative of an accumulated size of a sequence of transferred symbols and a currently transferred symbol. The comparator is configured to issue a symbol awareness signal, SAS, in case the current aggregated transactions' size, Sizetrans, exceeds the current aggregated expected symbols' size, Sizeexp.

摘要： Particular embodiments described herein provide for a communication system that can be configured for receiving, at a network element, a flow offload decision for a first service node. The flow offload decision can include a portion of a service chain for processing a flow and updating next hop flow based routing information for the flow. A next hop in the flow can insert flow specific route information in its routing tables to bypass a packet forwarder serving the service that offloaded the flow in the reverse direction.
