摘要： A method of allocating resource elements in an orthogonal frequency division multiplexed (OFDM) system for transmission of a channel state information reference signal (CSI-RS) is disclosed. The method includes converting one or more resource elements to a two-dimensional frequency-time domain; and partitioning the one or more converted resource elements to units of a physical resource block (PRB). One or more resource elements are patterned over at least a portion of the PRB for transmission of the CSI-RS. According to an embodiment, the CSI-RS resource elements with a same subcarrier index for a common cell are code division multiplexed (CDM), with a CDM dimension equal to a number of CSI-RS resource elements with the same subcarrier index for the common cell.

摘要： Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may perform a pre-distortion of a signal on a resource allocation for the signal and using discrete Fourier transform (DFT)-domain processing. For example, the transmitting device may perform a first frequency-domain (FD) to time-domain (TD) transform, which may be an example of an inverse DFT (IDFT), on a first set of FD symbols to obtain a first set of TD samples. A size of the first FD to TD transform may be based on the resource allocation for the signal. The transmitting device may perform a crest factor reduction (CFR) function on the first set of TD samples to pre-distort the signal in the TD (e.g., in the IDFT domain), which may enable the transmitting device to avoid out-of-band (OOB) emission or otherwise have greater control over where the pre-distortion contributes energy.

摘要： Methods, systems, and devices for wireless communication are described. A wireless device may determine that a serving base station supports multi-code and single-code transmissions, receiving a scheduling message having a cyclic redundancy check scrambled with a radio network temporary identifier (RNTI), determine resources for communicating with the serving base station based on the scheduling message, and communicate on the resources using coding associated with the single-code transmissions. A base station may identify at least one user equipment that supports single-code transmissions, transmit a scheduling message having a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI), wherein the scheduling message schedules the at least one user equipment for communication on resources using coding associated with the single-code transmissions and communicate with the at least one user equipment on the resources using the coding.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a dropping rule relating to: a first triggering communication, of a first transmit receive point (TRP), that triggers a first timeline for a first subsequent communication of the first TRP, and a second triggering communication, of a second TRP, that triggers a second timeline for a second subsequent communication of the second TRP, wherein the dropping rule indicates one or more communications to be dropped when the first triggering communication starts after a start of the second triggering communication and the first subsequent communication starts before a start of the second subsequent communication; and drop the one or more communications based at least in part on the dropping rule. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described in which uplink timelines may be reduced by initiating, at a user equipment (UE), uplink transmission processing prior to receipt of an uplink grant for an uplink communication. A UE may identify one or more uplink transmission parameters associated with a reduced uplink transmission timeline for an uplink communication, and use the uplink transmission parameters to initiate processing of the uplink communication prior to receiving an uplink grant from a base station. The uplink transmission parameters may allow for packet preparation at a higher layers (e.g., at a medium access control (MAC) layer or radio link control (RLC) layer) to be started or completed prior to receipt of the uplink grant.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a collision between a first resource for a downlink semi-persistent scheduled communication and a second resource for another downlink signal; and perform an action to mitigate the collision based at least in part on identifying the collision. In some aspects, a user equipment (UE) may identify a collision between a first resource for a downlink semi-persistently scheduled (SPS) communication and a second resource for another downlink signal; and determine an action, to be performed by a base station, to mitigate the collision based at least in part on identifying the collision; and selectively receive the downlink SPS communication or the other downlink signal based at least in part on the determination.

摘要： Wireless communications systems and methods related to serving wireless communication devices using multi-radio access technology (multi-RAT) transmission diversity are provided. A first wireless communication device communicates, with a second wireless communication device in a first frequency band allocated to a first radio access technology (RAT), first data using the first RAT. The first wireless communication device reconfigures a first resource in a second frequency band allocated to a second RAT different from the first RAT from implementing a configuration of the second RAT to implementing a configuration of the first RAT. The first wireless communication device communicates, with the second wireless communication device in the second frequency band, second data using the first resource implementing the configuration of the first RAT.
