  • Publication number: 20180092159
    Abstract: Aspects of the present disclosure provide methods and apparatus for improving UL-based mobility. As described herein, a UE may determine it has failed to decode a first keep alive (KA) signal during a wake period of a discontinuous receive (DRx) cycle and may extend the wake period to monitor for a second KA signal, in response to the determination. An access network controller may select, while a (UE) is currently served by a first transmit/receive point (TRP), a second TRP to serve the UE, configure the first TRP to transmit a first keep alive (KA) signal, in response to a chirp signal received from the UE, and configure the second TRP to transmit a second KA signal after the first KA signal transmitted by the first TRP.

  • Publication number: 20180092054
    Abstract: Certain aspects of the present disclosure provide techniques for supporting UL-based mobility without DL zone signals. A DL zone signal may refer to a zone synchronization signal or a zone measurement reference signal. As described herein, a UE may perform certain operations upon power-up or RLF recovery, perform operations in each DRx cycle, and/or perform inter-zone handovers without relying on DL zone signals. Thus, aspects create a more user-centric environment and reduce and/or avoid transmission DL zone signals.

  • Publication number: 20160285589
    Abstract: Various features pertain to mitigating interference on downlink/uplink channels caused by bursty traffic transmissions. A transmitting node encodes data into transport blocks, each including code blocks in which the data is encoded. The transport blocks are then wirelessly transmitted over a channel specific to a receiving node, where the code blocks of the transport blocks are transmitted without redundant parity code blocks or with a desired amount of redundant parity code blocks. The transmitting node then receives an indication from the receiving node of a number of failed data code blocks. The transmitting node generates an error correction code sufficient to recover all of the failed code blocks and transmits the error correction code within a new transport block along with new data.

  • Publication number: 20160269047
    Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.

  • Publication number: 20160173232
    Abstract: Coding for bursty interference is discussed in which a base station receives data bits for transmission. The base station may generate code blocks including information bits and parity bits. The base station may also generate parity check code blocks including information bits corresponding to information bits of the generated code blocks. The base station may transmit the code blocks and the parity check code blocks to a mobile device to improve decoding. When errors are detected, the mobile device may decode the received code blocks using hard or soft parity checks and the parity check code blocks.

  • Publication number: 20160150560
    Abstract: Methods, systems, and devices are described for wireless communication. In one method, a first transmission may be transmitted on a contention-based channel, and a scheduling request for the first transmission may be transmitted on a scheduled channel. The scheduling request may be transmitted prior to determining that an acknowledgment (ACK) message has been received for the first transmission. In another method, a scheduling request for a first transmission may be received on a scheduled channel from a wireless device. Upon decoding a reception of the first transmission on a contention-based channel, transmission of a transmission grant to the wireless device may be withheld. Upon failing to decode the reception of the first transmission on the contention-based channel, the transmission grant may be transmitted to the wireless device.
