Abstract: Embodiments of the disclosure generally relate to transmission of TA information in a non-paging procedure. A network device receives, from a source node, a first message that is a non-paging message. The source node is one of a terminal device and a control device in a core network. Then, the network device obtains TA information about the terminal device from the first message and transmits, to a destination node, a second message generated based on the first message. The destination node is the other of the terminal device and the control device.

Abstract: A wireless device receives at least one radio resource control (RRC) message comprising a field indicating a starting symbol for an enhanced physical downlink control channel (ePDCCH). The wireless device receives ePDCCH signal in a subframe. The ePDCCH starts from the starting symbol when the subframe is a full subframe. The ePDCCH starts from the starting symbol plus an offset value when the subframe is a partial subframe.
Abstract: Embodiments of the present invention provide a method for enhancing a processing capability of a base station, a baseband device, a base station, and a system. The method includes: receiving, by a base station, data of a terminal; performing control plane protocol processing on the terminal by using a first BBP, and performing all or part of data transmission protocol processing on the data of the terminal by using a second BBP; and sending processed data of the terminal. In this way, another BBP shares all or part of data transmission protocol processing for a terminal that accesses a BBP, to enhance a processing capability of the base station on the whole, thereby implementing inter-board load balancing.

Abstract: A wireless device receives a downlink control information (DCI) comprising SRS request field indicating whether an SRS is transmitted in the last symbol of the subframe; and an ending symbol field for a physical uplink shared channel (PUSCH) indicating whether the PUSCH is transmitted in a last symbol of the subframe. The wireless device transmits, in the subframe, one or more transport blocks based on the ending symbol field. The wireless device transmits the SRS signal in the last symbol of the subframe when the SRS request field indicates that SRS transmission is triggered. The DCI may further indicate a multi-subframe grant (MSFG).
Abstract: Communication apparatus includes a TCAM, which stores a corpus of rules, including respective sets of unmasked and masked bits. The rules conform to respective rule patterns, each defining a different, respective sequence of masked and unmasked bits to which one or more of the rules conform. A RAM caches rule entries corresponding to rules belonging to one or more of the rule patterns that have been selected for caching. Decision logic extracts respective classification keys from data packets, each key including a string of bits extracted from selected fields in a given data packet, and classifies the data packets by first matching the respective classification keys to the cached rule entries in the RAM and, when no match is found in the RAM, by matching the respective classification keys to the rules in the TCAM.

Abstract: Extended DRX (e-DRX) operation using hyper frame extension signaling are described. The hyper frame extension signaling may extend the system frame number (SFN) range while maintaining backward compatibility for legacy devices not configured to use the extended SFN range. The hyper-SFN extension signaling may include an index to a hyper-SFN transmitted as part of system information different than that used for transmission of the SFN. UEs configured to use the hyper-SFN may effectively use a longer or extended SFN range that includes the legacy SFN range and the hyper-SFN range. The hyper-SFN extension may be used in an extended idle DRX (eI-DRX) mode which may coexist with existing I-DRX mode on the same paging resources. Additionally or alternatively, paging may be differentiated for eI-DRX mode UEs using separate paging occasions or a new paging radio network temporary identifier (RNTI).

The system further includes a cellular device connectivity (CDC) service module operatively associated with the DRA for providing SCEF services as a feature of the DRA, the SCEF services including determining whether to invoke Internet of things (IoT) service handling based on content of received messages and for forwarding messages requiring IoT service to a service capability server (SCS) or an application server (AS) for receiving the IoT service handling.
Abstract: A method of multicasting packets by a forwarding element that includes several packet replicators and several egress pipelines. Each packet replicator receives a data structure associated with a multicast packet that identifies a multicast group. Each packet replicator identifies a first physical egress port of a first egress pipeline for sending the multicast packet to a member of the multicast group. The first physical egress port is a member of LAG. Each packet replicator determines that the first physical egress port is not operational and identifies a second physical port in the LAG for sending the multicast packet to the member of the multicast group. When a packet replicator is connected to the same egress pipeline as the second physical egress, the packet replicator provides the identification of the second physical egress port to the egress pipeline to send the packet to the multicast member. Otherwise the packet replicator drops the packet.
Abstract: The invention relates to a technique for access by a master device (22) to a value. The invention relates to a technique for access by a master device (22) to a value taken by a characteristic managed by a peripheral device (23). A first relay device (21) situated in a zone of radio coverage of the master device receives a command for simulation of the peripheral device, this peripheral device being situated in a zone of radio coverage to a second relay device (24). The first relay device then establishes a radio connection with the master device, by simulating the presence of the peripheral device in the zone of radio coverage of the master device. The first relay device receives from the master device a request to read a value taken by a characteristic managed by the peripheral device, transmits the request and receives in return the value from the second relay device, said second relay device having obtained it by interrogating the peripheral device. It can then dispatch it to the master device.
