  • Patent number: 9900033
    Abstract: Methods, apparatuses, and systems are described related to interference averaging to generate feedback information and interference averaging to demodulate receives signals. In embodiments, an evolved Node B (eNB) may transmit interference averaging information to a user equipment (UE) including a time domain averaging indicator indicating a time domain averaging window to be used by the UE for averaging interference measurements in a time domain or a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain. Additionally, or alternatively, the eNB may transmit an interference resource group (IRG) indicator to the UE to indicate an IRG over which the UE is to perform interference averaging to facilitate demodulation of signals received by the UE from the eNB.

  • Patent number: 9883432
    Abstract: Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.

  • Patent number: 9749995
    Abstract: The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.

  • Publication number: 20170111898
    Abstract: Technology for a user equipment (UE) to report periodic channel state information (CSI) is disclosed. The UE can generate a plurality of CSI reports for serving cells for transmission in a subframe. Each CSI report can correspond to a physical uplink control channel (PUCCH) reporting type among a plurality of CSI processes having a CSI process index (CSIProcessIndex) and a serving cell index (ServCellIndex). The UE can determine different priorities corresponding to each of the plurality of PUCCH reporting types. The UE can drop CSI reports corresponding to all CSI processes except a CSI process having the lowest CSIProcessIndex. The UE can drop CSI reports corresponding to all ServCellIndexes except a CSI report with the lowest ServCellIndex. The UE can multiplex at least one non-colliding CSI report from among CSI reports that are not dropped and hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback bits for transmission to an eNodeB.

  • Patent number: 9572063
    Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (UE) experiences enhanced signal reception and/or reduced interference. In order to optimally implement downlink CoMP, a serving cell needs to obtain channel state information (CSI) for the downlink channels from the multiple transmission points to the UE. This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.
