Abstract: Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.

Abstract: Coverage holes are identified and appropriate action taken in response thereto. The identification of a coverage hole may be based on, for example, measurements taken at an access point, measurement report messages from an access terminal, idle user registrations, active user handovers, or handover history. Upon identification of a coverage hole, action may be taken to mitigate (e.g., reduce or eliminate) the coverage hole and/or avoid the coverage hole. For example, in some embodiments, access point resources such as power, frequency and time are allocated accordingly. The action to be taken may depend on whether a coverage hole is noise-limited or interference-limited. In some embodiments, the manner in which handovers are conducted is modified upon identification of a coverage hole. The above actions may be performed entirely at an access point.
Abstract translation: 识别覆盖孔并响应于此而采取适当的动作。 覆盖孔的识别可以基于例如在接入点处进行的测量，来自接入终端的测量报告消息，空闲用户注册，主动用户切换或切换历史。 在识别覆盖孔时，可以采取行动来减轻（例如，减少或消除）覆盖孔和/或避免覆盖孔。 例如，在一些实施例中，相应地分配诸如功率，频率和时间的接入点资源。 要采取的行动可能取决于覆盖孔是否受到噪声限制或受干扰限制。 在一些实施例中，在识别覆盖孔时修改切换切换的方式。 上述动作可以完全在接入点执行。

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for beam recovery and radio link failure (RLF) in communications systems using beamforming and operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes communicating using beamforming with a base station (BS) via a transmit beam and a receive beam of an active beam pair and obtaining an indication of one or more alternative beams for the UE to use to send a beam recovery message to the BS in the event the transmit beam and the receive beam of the active beam pair become misaligned.

Abstract: Certain aspects of the present disclosure provide to techniques for radio link monitoring (RLM), detecting beam failure, and beam failure recovery (BFR) using radio link monitoring reference signal (RML-RS) resources and beam failure recovery reference signal (BFR-RS) resources. An exemplary method by a user equipment (UE) may include obtaining a first configuration indicating one or more radio link monitoring reference signal (RLM-RS) resources and one or more beam failure recovery reference signal (BFR-RS) resources, wherein each RLM-RS resource corresponds to at least a first link, and each BFR-RS resource corresponds to at least a second link, obtaining a first indication that a first link quality for the first link is below a first threshold and a second link quality for the second link is above a second threshold, and taking action regarding a radio link failure (RLF) based on the indication.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may be configured to transition to communicating on a first bandwidth part from communicating on a second bandwidth part. In order to ensure that the UE is able to perform receiver processing for demodulating data received on the first bandwidth part, after transitioning to communicating on the first bandwidth part, the UE may be configured to perform receiver processing using reference signals received on the second bandwidth part. That is, for a configured period of time, before the UE is able to perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the first bandwidth part, the UE may perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the second bandwidth part.

Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

Abstract: A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Abstract: A node for wireless communication identifies a number of actually transmitted reference signals. The node identifies a number of available PRACH time-frequency resources and preamble indices in a time period. The node identifies a number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node determines that the available number of PRACH time-frequency resources or PRACH preamble indices within the time period is not an integer multiple of the product of the number of actually transmitted reference signals and the number of configured PRACH time-frequency resources or PRACH preamble indices per reference signal. The node maps the actually transmitted reference signals to the available PRACH time-frequency resources and preamble indices based on the identified information and determination.

Abstract: Aspects of the present disclosure describe transmitting beams in wireless communications. A plurality of downlink beams having different beamforming directions can be received from a base station. Downlink pathloss values associated with each of the plurality of downlink beams can be measured. A transmit power for transmitting a plurality of uplink beams can be determined based on at least one of the downlink pathloss values. The plurality of uplink beams in multiple beamformed directions can be transmitted based on the transmit power.

Abstract: A user equipment (UE) may transmit a power headroom report in response to changing beamforming parameters. The UE may autonomously change beamforming parameters from a preconfigured set of beams or receive a command to change beamforming parameters for transmissions on a new beam. The UE may determine a power headroom applicable to a transmission from the UE on the new beam. The UE may transmit, in response to the command, a power headroom report based on the power headroom using resources configured for the power headroom report. For example, the power headroom report may be multiplexed with an uplink transmission from the UE using the new beam. In an aspect, the UE may select a scheduled transmission during a time period after the command is implemented as the uplink transmission. For example, the power headroom report may be transmitted as a physical layer transmission or as a MAC-CE transmission.
