Abstract: Aspects provide for selecting a precoder mode for a transmission, changing a cyclic prefix (CP) length based on the selected precoder mode, and transmitting a signal that includes the changed CP length. Changing the CP length may involve using the selected precoder mode to lookup a value by which to change a nominal CP length. After changing the CP length, information indicating the changed CP length may be transmitted to a receiver of the signal. Precoder mode selection may be based on feedback information that indicates whether a receiver requests a change to the CP length. Precoder mode selection may be based on a received reference signal that indicates a condition of a communication channel. The reference signal may be used to select the precoder mode that results in the smallest relative delay spread, the largest relative delay spread compression, the largest relative beamforming gain, and/or the largest relative throughout.

Abstract: Aspects of the present disclosure describe a guard band signal for communication on a guard band between a first frequency band utilized by a first radio access technology having a first sub-carrier spacing and a second frequency band utilized by a second radio access technology having a second sub-carrier spacing that is a multiple of the first sub-carrier spacing. The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) capable of supporting multiple antenna ports may determine that some combinations of antenna ports can be used simultaneously. The UE may make this determination by evaluating the relationships between the physical antennas and the transmit chains included in the UE. Upon determining that the combinations of antenna ports can be used simultaneously, the UE may send a message to a base station. The message may indicate whether two or more antenna ports can be used at the same time. The UE may communicate simultaneously over one or more antenna ports based on the scheduling information from the base station which takes into account the ability of the combination of antenna ports to be used concurrently.

Abstract: Methods, systems, and devices for wireless communication are described that provide for establishing periodic resources that may be used for low latency communications. An indication channel may be provided that may indicate that one or more higher latency transmissions may be punctured with low latency communications that are transmitted outside of the periodic resources. In some cases, the indication channel may be transmitted only in subsets of time resources, such as mini-slots of time resources within a slot, and a user equipment (UE) may monitor the indication channel to determine that a transmission is punctured. The UE may not monitor the indication channel in the periodic resources, and may thus conserve power compared to monitoring the indication channel in all time resources.

Abstract: A method at a scheduling entity might include determining that interference is present from a neighboring scheduling entity, which implements a second subcarrier spacing that is different from a first subcarrier spacing of the scheduling entity. The scheduling entity might request the neighboring scheduling entity to negotiate a bandwidth group (BWG), where the BWG is a bandwidth occupied by downlink subcarriers within which a transmission parameter is maintained. The method might include negotiating a bandwidth of the bandwidth group and transmitting, if negotiating is successful, downlink data to a scheduled entity served by the scheduling entity according to the negotiated bandwidth. The transmission parameter might be a precoder, rank, modulation order, power inside each BWG, or numerology. The numerology might be scalable and might be a combination of subcarrier spacing and cyclic prefix (CP) overhead, The subcarrier spacing might be scaled while keeping constant the CP overhead as a percentage of a symbol duration.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) device, control information indicating a condition associated with a demodulation reference signal (DMRS) grouping characteristic of a DMRS that is to be wirelessly communicated using one or more physical (PHY) channels. The method further includes performing the wireless communication based on the DMRS grouping characteristic indicated by the control information. The wireless communication is performed in response to detecting, by the UE device, that a first full duplex resource configuration associated with a first slot of a plurality of slots of a wireless communication and a second full duplex resource configuration associated with a second slot of the plurality of slots satisfy the condition.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.
