摘要： An apparatus and method for positioning a pilot in a transmitter for an Orthogonal Frequency Division Multiple Access (OFDMA) mobile communication system. In the apparatus, a consecutive block assignment determiner determines whether it will assign a consecutive block or a single block in a frequency axis or a time axis. A pilot tone pattern generator determines a pilot pattern in the block by applying a predetermined rule according to the determination result. A pilot tone inserter positions pilots in the block based on the determined pilot pattern.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal indicating a codebook construction configuration for constructing a codebook of sequences for conveying a first type of uplink payload in a resource block that is orthogonal to a second type of uplink payload transmitted from a second UE in the resource block. The UE may construct the codebook of sequences for the first type of uplink payload according to the codebook construction configuration. The UE may generate the first type of uplink payload for transmission using a first sequence from the codebook of sequences. The UE may transmit the first type of uplink payload in the resource block, wherein the first type of uplink payload is multiplexed in the resource block with the second type of uplink payload from the second UE.

摘要： Aspects of the disclosure relate to radio access networks with a capability to dynamically reconfigure a number of transmission-reception points (TRPs) in a single-frequency network (SFN) based on channel measurements. In one example, a mobile device receives a configuration message including a plurality of transmission configuration indicator (TCI) states, and potentially further including an indication identifying one or more of the TCI states as main TCI states. The message may further include an indication that it includes the plurality of TCI states. The UE receives a downlink traffic channel and demodulates the traffic channel based on only a subset of the TCI states (e.g., the main TCI state (s)). The UE further measures one or more channel parameters corresponding to each TCI state of the plurality of TCI states, and transmits a channel state information report based on the channel parameters. Other aspects, embodiments, and features are also claimed and described.
