摘要： Methods, systems, and devices for wireless communications are described. A method for wireless communication may include receiving a single frequency networked composite reference signal (SFNed RS) at a first port of a user equipment (UE) and receiving a reference signal (RS) at a second port of the UE that is different than the first port of the UE. The method may also include performing channel estimation for at least one of the first port or the second port based at least in part on receiving the SFNed RS and the RS. A method for wireless communication may include transmitting a first portion of an SFNed RS from a first port of a first transmit/reception point to a UE and transmitting a downlink control information message to the UE that indicates at least one transmission configuration indicator state identifier that identifies the SFNed RS.

摘要： Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

摘要： This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for interference measurement and reporting by a UE. The interference measurement can be self-initiated by the UE or based on a request received from a BS. To measure the interference, the UE transmits a first signal in UL resources to a first BS concurrently with receiving a second signal in DL resources from one of the first BS or a second BS. The received second signal includes interference associated with the transmitted first signal. Based on the received second signal, the UE determines a level of the interference that is associated with the transmitted first signal. Information associated with the level of the interference is then transmitted to the first BS, such as an indication of a guard band that is to be incorporated between the UL resources and the DL resources.

摘要： Described techniques provide for communications using multiple different transmission time intervals (TTIs) while in a configured DRX mode that allows efficient scheduling and allocation of resources, and relatively efficient power usage at a user equipment (UE). In some cases, two or more available TTIs for transmissions between a base station and a UE may be identified, and a DRX cycle configured based at least in part on the available TTIs. During monitoring periods of a configured DRX cycle for a first TTI, the UE may be configured to monitor for control signal transmissions associated with a different TTI duration. In some cases, resources for a shorter TTI may be allocated using a two-stage grant. In some cases, multiple component carriers may be configured for one or more different TTIs, and one component carrier may be used to cross schedule resources on other component carriers.

摘要： Symbol alignment and power scaling are provided for different length transmission time intervals (TTIs) within predefined boundaries, such as boundaries of a slot of a subframe. Described techniques provide for identifying time and/or frequency resources for one or more TTIs and allocating such resources based on a location within a subframe, pilot signals that may be transmitted using the resources, other processing timelines, or any combination thereof. In some cases, a power allocation for symbols within a TTI may be determined based on the allocated resources for the TTI. Frequency hopping patterns and power scaling for three-symbol TTIs are also provided.

摘要： Various aspects relate to determining whether one or more subframes are multicast-broadcast single-frequency network (MBSFN) subframes. A user equipment (UE) can receive, from a base station, a system information broadcast signal that includes an indication of one or more subframes as MBSFN subframes, and a subsequent system information broadcast signal that indicates at least scheduling information for a multicast control channel (MCCH) in at least a portion of the one or more subframes. The UE can determine, based at least in part on the indication or on the subsequent system information broadcast signal, a numerology for a physical multicast channel (PMCH) corresponding to the MCCH in at least the portion of the one or more subframes, and can process at least the portion of the one or more subframes based at least in part on the scheduling information or the numerology for the PMCH.

摘要： Methods, systems, and devices for wireless communication are described. A base station may allocate resources for communication with a user equipment (UE). The resources may include one or more subframes, and each subframe may include one or more shortened transmission time intervals (sTTIs). Each sTTI may be assigned a transmission direction according to a time division duplex (TDD) pattern. Based on traffic needs and/or interference from other UEs and/or base stations, the base station may determine to modify the TDD pattern used for communication. Accordingly, a base station may transmit an indicator in a control message or control region of a TTI or sTTI, to indicate to users that a transmission direction of an sTTI in the TDD pattern is being changed. Subsequently, a user may communicate with the base station according to the reconfigured TDD pattern.
摘要翻译：描述了用于无线通信的方法，系统和设备。基站可以分配用于与用户设备（UE）进行通信的资源。资源可以包括一个或多个子帧，并且每个子帧可以包括一个或多个缩短的传输时间间隔（sTTI）。每个sTTI可以根据时分双工（TDD）模式被分配传输方向。基于来自其他UE和/或基站的业务需求和/或干扰，基站可以确定修改用于通信的TDD模式。因此，基站可以在TTI或sTTI的控制消息或控制区域中发送指示符，以向用户指示TDD模式中的sTTI的传输方向正在改变。随后，用户可以根据重新配置的TDD模式与基站进行通信。

摘要： Modifiable guard periods are provided for time division duplexing (TDD) wireless communications. Guard periods may be modified based at least in part on propagation delay information, such as timing advance (TA) information, for one or more user equipment (UE) in a TDD wireless system. Modifiable guard periods may allow for enhanced system efficiency for the TDD wireless system relative to systems that may use a static or semi-statically configured guard period for TDD communications. Modifiable guard periods may in some cases allow one or more uplink or downlink transmissions to be provided within a legacy guard period of a legacy TDD special subframe.
