Each of the SDU elements is a SDU or SDU segment. The PDU includes the SDU elements and respective SNs for the SDU elements.

Abstract: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARD) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

And it may be determined that communication between the cell of the access node and the wireless device is experiencing interference from a neighboring cell when the monitored rate and monitored retransmission metric meet the interference criteria.

Abstract: A method, apparatus and system for establishing S1 signaling connections in an evolved network are disclosed. A source evolved NodeB (eNodeB) sends a handover request message to a target eNodeB to initiate a handover procedure during that a user equipment (UE) is handed over from the source eNodeB to the target eNodeB. The handover request message includes information about an original S1 signaling connection parameter. When the UE enters the target cell, the target eNodeB allocates a new S1 signaling connection parameter and sends a handover complete message to an evolved packet core (EPC). The handover complete messages carries the original S1 signaling connection parameter received from the source eNodeB and the allocated new S1 signaling connection parameter about the target eNodeB. With the present disclosure, the inability of the target eNodeB to establish an S1 signaling connection with the EPC in the related art is effectively solved.

Abstract: Concepts and technologies disclosed herein are directed to an enhanced software-defined networking (“SDN”) controller to support ad-hoc radio access technologies (“RATs”). An SDN controller receives, from an ad-hoc radio access controller serving an ad-hoc radio access network (“RAN”), an attach request sent on behalf of a user equipment (“UE”) operating in communication with an ad-hoc RAT transceiver node. The attach request includes a physical IP address associated with the UE. The physical IP address includes an IP address sub-interface pre-fix broadcast to the UE by the ad-hoc RAT transceiver node combined with a physical address of the UE. In response to the attach request, the SDN controller can complete an attachment procedure for allowing the ad-hoc radio access controller to an SDN network. The SDN controller also can update one or more components operating within the SDN network to reflect how to reach the UE via the physical IP address.

Abstract: Methods, systems, and devices for wireless communication are described. A receiving device may detect a signal associated with low latency transmissions and decode a non-low latency communication accordingly. The receiving device may receive an indicator from a transmitting device that indicates where and when low latency communications occur. The indication may specify frequency resources or symbols used by the low latency communication. The indicator may be transmitted during the same subframe as the low latency communication, at the end of a subframe, or during a subsequent subframe. The receiving device may use the indicator to mitigate low latency interference, generate channel estimates, and reliably decode the non-low latency communication. In some cases, the interfering low latency communication may occur within the serving cell of the receiving device; or the interfering low latency communication may occur in a neighboring cell.

Abstract: In data transmissions, a processing method for hybrid automatic repeat request (HARQ) is applied to a transmitter transmitting a first semi-persistent scheduling (SPS) data packet to a receiver. The receiver receives the first SPS data packet and transmits feedback to the transmitter. The transmitter which receives the feedback message can determine that a transmission of a repeat SPS data packet is required when the feedback message is a negative acknowledgement, and a repeat SPS data packet together with a HARQ ID corresponding to the repeat SPS data packet is transmitted to the receiver. If the receiver can match the repeat SPS data packet with the first SPS data packet according to the HARQ ID, a combination of the first SPS data packet and the repeat SPS data packet can be decoded.

Abstract: A method and system uses a constrained set of indexed samples to identify a next generation population of samples that exhibits a more desirable signal characteristic such as lower PAPR, out-of-band emission and error vector magnitude. The invention generates an intermediate set of indexed samples which are subjected to a fitness function and next generation calculations to produce next generation indexes for the next population of samples. The next generation indexes population of samples is further constrained over initial indexes for generating a more desirable signal characteristic. In dynamic spectrum access networks having OFDM components, the interference between collections of overlay and underlay signals is adaptively controlled based on the composite PAPR. In an example, the total out-of-band interference for the collection of overlay and underlay signals for all samples of the population are reduced.

Abstract: Simulating sector changes in an application module (AM) in a wireless communications system (WCS) to simulate site walks in the WCS. The AMs are wireless telecommunication circuitry wired or wirelessly associated with wireless communications system components in a WCS. In one embodiment, the AMs are configured to determine signal information (e.g., signal strength, power and/or quality) of live communications signals in a WCS. The measured signal strength values are then artificially changed to simulate a site walk in the WCS. For example, the signal strength of communication signals received by an AM from a particular sector can be artificially lowered so that the signal strength from a neighboring sector located further away from the AM appears to be stronger. In this manner, a site walk of the AM in the sectors in which communications signals are received by the AM in the WCS can be simulated.
