  • Publication number: 20190238193
    Abstract: Methods and apparatus adapted to address asymmetric conditions in a multi-antenna system. In one embodiment, the multi-antenna system comprises a wireless (e.g., 3G cellular) multiple-input, multiple-output (MIMO) system, and the methods and apparatus efficiently utilize transmitter and receiver resources based at least in part on a detected asymmetric condition. If an asymmetric condition is detected by the transmitter on any given data stream, the transmitter can decide to utilize only a subset of the available resources for that stream. Accordingly, the signal processing resources for that data stream are adapted to mirror the reduction in resources that are necessary for transmission. The transmitter signals the receiver that it will only be using a subset of the resources available, and the receiver adapts its operation according to the signaling data it receives. The multi-antenna system can therefore reduce power consumption as well as increasing spectral efficiency on the network.

  • Publication number: 20190090103
    Abstract: Downlink spectral capacity of an eMBMS cell to be maximized for the eMBMS users. In one embodiment, supplementary eMBMS cells may be used together with a primary cell, in which the supplementary eMBMS cells broadcast only eMBMS content and the primary cell is used for uplink and downlink signaling. The primary cell may perform signaling for the corresponding supplementary cells. In this manner, signaling relating to configuring of the eMBMS cells may be offloaded to the non-eMBMS primary cell and eMBMS specific services can be fully utilized from the eMBMS cells. In a second embodiment, an eMBMS cell may be a standalone eMBMS cell that is not associated with a primary cell. In this embodiment, self-contained eMBMS signaling is defined. Additionally, eMBMS data may be broadcast in specified MBSN subframes. In this manner, a device, such as an eMBMS-only device, can independently receive eMBMS services.

  • Patent number: 10237680
    Abstract: Technology described herein provides carrier-monitoring (CM) signaling approaches that can be used by networks and/or mobile devices. An evolved Node B (eNB) can send an IncMon-support message indicating whether a network supports the increased-number-of-frequencies-to-monitor (IncMon) feature. A UE can apply a default CM configuration if the UE does not receive an IncMon-support message from the eNB. The eNB can use dedicated signaling or broadcast signaling to inform a UE of a default CM configuration or one or more adopted CM configurations that are used in the network. The eNB can also send a list of carriers that are to be monitored to the UE. The UE can also send UE-capability information to the eNB, such as a default CM configuration, an adopted CM configuration, or configurable configurations in different radio access technologies (RATs) supported by the UE.

  • Publication number: 20190082419
    Abstract: Methods and apparatus enabling a wireless network to optimize paging channel operation, based on mobile device context information. In one embodiment, the wireless network is a cellular network (e.g., LTE-Advanced), and both base stations and cellular user devices dynamically exchange and maintain a paging agreement. The paging agreement limits the paging channel operation, thereby minimizing unnecessary scanning and usage of irrelevant radio resources. Such paging mechanisms ate limited to the air interface between the base station and the mobile device, and are compatible with existing legacy devices and network entities. Networks with appropriately enabled user devices may improve their resource utilization. Base stations may advantageously reclaim freed-up cellular resources to support other services.

  • Patent number: 10206102
    Abstract: Methods and apparatus that provide user access control within wireless networks such as those having both fixed and portable nodes. In one embodiment, the network comprises a 3G cellular network or Interworking WLAN (iWLAN), and the portable nodes comprise Home Node B (HNB) base stations. The HNB is configured to authenticate new users, and provide network access while still maintaining user privacy. The portable nodes also may operate in a number of different operating modes which provide different functional control over user access. In one variant, an easy-to-use owner-assigned ID based access control mechanism with a reliable unambiguous user ID is utilized. Methods for providing access control across differing network architectures and protocols, such the aforementioned iWLAN, and business methods, are also described.
