摘要： Methods and apparatuses are provided that facilitate allocating a portion of a resource block to a power-limited device for communicating therewith. The power-limited device may not be capable of transmitting over an entire resource block due to power limitations; thus, a portion of the resource block can be assigned thereto, allowing for allocating at least a different portion of the resource block to at least one different device to optimize communications over the resource block. In addition, the portion of the resource block can be allocated across one or more bundled time transmit intervals (TTI) to allow for effective communication of time-sensitive data, such as voice over internet protocol (VoIP).
摘要翻译：提供的方法和装置有助于将资源块的一部分分配给功率受限设备以与之通信。由于功率限制，功率受限设备可能不能够在整个资源块上传输; 因此，资源块的一部分可以被分配给它，允许将资源块的至少不同部分分配给至少一个不同的设备，以优化资源块上的通信。此外，资源块的一部分可以跨越一个或多个捆绑的时间发送间隔（TTI）分配，以允许时间敏感数据（例如因特网协议语音（VoIP））的有效通信。

摘要： Techniques for sending a MIMO transmission in a wireless communication system are described. In one design, a transmitter sends a first reference signal to a receiver. The receiver selects a precoding matrix based on the first reference signal and in accordance with a selection criterion. The receiver estimates noise and interference at the receiver and determines channel quality indicator (CQI) or modulation and coding scheme (MCS) information based on the precoding matrix and the estimated noise and interference. The receiver sends the CQI or MCS information and a second reference signal to the transmitter. The transmitter selects the precoding matrix based on the second reference signal and in accordance with the same selection criterion used by the receiver. The transmitter then sends a MIMO transmission to the receiver based on the CQI or MCS information obtained from the receiver and the precoding matrix selected by the transmitter.

摘要： Techniques for transmitting data and pilot for control information are described. In one aspect, a user equipment (UE) may spread a reference signal sequence with a first orthogonal sequence to obtain multiple pilot sequences. The UE may then send the multiple pilot sequences on multiple subcarriers in multiple symbol periods, one pilot sequence in each symbol period. The UE may modulate the reference signal sequence with control information (e.g., ACK information) to obtain a modulated sequence. The UE may spread the modulated sequence with a second orthogonal sequence to obtain multiple data sequences. The UE may then send the multiple data sequences on the multiple subcarriers in multiple symbol periods for data. In another aspect, the UE may send multiple pilot sequences on multiple subcarriers in multiple symbol periods separated by at least one symbol period, one pilot sequence in each symbol period.

摘要： Techniques for transmitting control information in a wireless communication system are described. The system may support acknowledgement (ACK) channels and channel quality indicator (CQI) channels, which may have different target signal-to-noise ratios (SNRs). The ACK and CQI channels from different user equipments (UEs) may be multiplexed on the same resource block. In one design, the transmit power of a CQI channel may be set to achieve a nominal target SNR for CQI when not multiplexed with the ACK channels and may be reduced to achieve a lower target SNR when multiplexed with the ACK channels. In another design, the transmit power of an ACK channel may be set to achieve a nominal target SNR for ACK when not multiplexed with the CQI channels and may be boosted to achieve a higher target SNR when multiplexed with the CQI channels. The CQI channel may randomly hop to mitigate performance degradation.

摘要： Techniques for performing rank-dependent precoding for a MIMO transmission are described. Each rank may be associated with a set of at least one precoding vector or matrix that can provide good performance for that rank. A transmitter may obtain a precoding vector for a rank-1 transmission from a first set containing at least one column vector of a unitary matrix, e.g., a Fourier matrix. The transmitter may perform precoding for the rank-1 transmission based on the precoding vector. The transmitter may obtain a precoding matrix for a rank-2 transmission from a second set containing an identity matrix. The transmitter may perform precoding for the rank-2 transmission based on the precoding matrix. For the rank-2 transmission, the transmitter may select the identity matrix as the precoding matrix if a MIMO channel resembles a diagonal channel (which may be determined based on antenna configurations) and may select the unitary matrix otherwise.

摘要： Aspects relate to sharing a channel occupancy time (COT) initiated by a network access node (e.g., a base station) with one or more wireless communication devices for sidelink communication between the wireless communication devices. In this example, the network access node can transmit a COT structure indication (COT-SI) to the wireless communication device (s) indicating the COT resources (e.g., time and frequency resources) of the COT that may be shared with sidelink. In some examples, the wireless communication device can receive a message from the network access node including a COT sharing indicator indicating whether COT sidelink sharing is enabled or disabled.

摘要： Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit a sidelink message in accordance with one or more parameters associated with a priority of the sidelink message. The UE may determine a channel access priority class (CAPC) associated with the sidelink message based on the priority of the sidelink message. The UE may perform a listen-before-talk (LBT) procedure in accordance with the CAPC to gain access to a wireless channel for a channel occupancy time (COT). The UE may select a set of starting positions relative to the COT based on the priority, the CAPC, or both. The UE may transmit the sidelink message within the COT based on a starting position of the set of starting positions and the LBT procedure. The UE may perform a quantity of one or more retransmissions of the sidelink message based on the CAPC.
