摘要： Various aspects of the disclosure relate to channel sensing for independent links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a first TRP) via a first link and communicate with a third device (e.g., a second TRP) via a second link. In some scenarios, first channel sensing information may be obtained for the first link and second channel sensing information may be obtained for the second link. In some aspects, a decision of whether to transmit via one or more of the links may be based on the channel sensing on one or more of the links. In some cases, the links may be grouped together as a channel sensing group.

摘要： Channel state information (CSI) request procedures are disclosed for use in long term evolution (LTE)/LTE-Advanced (LTE-A) networks with unlicensed spectrum. Instead of relying on periodic reference signals which may not be transmitted because of failed clear channel assessment (CCA) operations, an aperiodic reference signal is defined that provides an on-demand reference signal and CSI request for user equipment (UE). The serving base station transmits an identifier, which signals that the aperiodic reference signal will be transmitted, either in the same subframe or a future subframe, and then transmits the aperiodic reference signal in the designated subframe. UEs served by the base station will receive the identifier, identify a CSI request, either implicitly through the identifier signal received from the base station or explicitly through a UE-specific CSI request, and then generate a CSI report based on the aperiodic reference signal for transmission back to the serving base station.

摘要： Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

摘要： Methods, systems, and devices for soft hybrid automatic repeat request operation in wireless communication are described. A user equipment (UE) may fail to decode a received signal, for example. The UE may store a portion of the signal in a buffer if the signal size is greater than the buffer size; otherwise, the UE may store the entire signal in the buffer. The UE may then receive a second signal and combine the second signal with the stored portion of the first signal; the combined signal may be larger than the buffer size. This combined signal may, for example, have a code rate less than the first signal. The UE may perform a second decoding attempt on the combined signal. The UE may determine that the second decoding attempt failed and may store a portion of the combined signal in the buffer.

摘要： Techniques are provided for accessing a shared radio frequency spectrum band by selecting a subset antennas associated with a successful access procedure for accessing the shared radio frequency spectrum. In some examples, a wireless communication device, such as a network node, may perform a listen before talk (LBT) procedure for each of two or more subsets of antennas associated with the network node, and only those subsets of antennas that pass the LBT procedure are used for transmissions during the associated time period, while other antennas are idle, or used for transmissions on another radio frequency spectrum band during the associated time period. In some examples, antennas of a wireless communication device may perform an access procedure utilizing beamforming capabilities of associated antennas to determine one or more different spatial directions that may provide access to the shared radio frequency spectrum band.

摘要： Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

摘要： Methods, systems, and devices for wireless communications are described, and relate to a base station to communicating with a user equipment (UE) over a channel. A first device (for example, the base station or the UE) may use a trained neural network to estimate one or more link performance metrics associated with the channel. Predicting the link level performance may include determining one or more neural network weights associated with one or more input parameters associated with the channel to estimate the one or more link performance metrics. The first device may report feedback to the second device based on the estimated link performance metrics. Based on the feedback, the second device may adapt the link by adjusting channel parameters to improve the reliability or efficacy of later transmissions.

摘要： Improvements to asynchronous spatial listen before talk (LBT) procedures are disclosed. In a shared spectrum network spatial LBT procedures are used for directionally targeting the channel reservation process. Prior to transmitting channel reservation signaling, the transmitter and receiver determine an effective interference considering available multiple input, multiple output (MIMO) configuration information. When the effective interference exceeds a predefined threshold, the node may without transmission of its channel reservation signal. Otherwise, when the effective interference remains within the threshold, each node's transmitted channel reservation signal may also identify at least a beamforming matrix either as payload or used to precede the node's channel reservation signal.
