    Abstract: A method of wireless communication includes grouping, by a network device, rate matching resources into a plurality of first groups for communication with a wireless terminal and transmitting a channel control indicator identifying at least a first group from the plurality of first groups of rate matching resources. In various embodiments, the rate matching resources include one or more of a rate matching pattern comprising multiple time-frequency transmission resources, a periodic zero power channel state information reference signal (ZP CSI-RS) resource set, an aperiodic ZP CSI-RS resource set, a semi-persistent ZP CSI-RS resource set, a long-term evolution cell specific reference signal (LTE CRS) resource, or a rate matching pattern group.

    Abstract: Disclosed are techniques, systems, apparatuses, and methods of wireless communication. In one aspect, a method of wireless communication is disclosed. The method includes transmitting, by a first communications node to a second communications node, a set of information for transmission of reference signals or channels, wherein the set of information includes: timing information related to a transmission timing of the reference signals or channels, timing information related to when an antenna group or a group of reference signals and/or channels related to the antenna group is activated, or an identification of one or more antenna groups associated with the reference signals or channels.

    Abstract: In one configuration, multiple TRPs, or base stations such a next generation node B (gNB) base stations send different transport blocks (TBs) to a user equipment (UE) at the same time or at different times. In another configuration, multiple base stations may send the same data at the same time to a UE. When the same data is being sent by multiple base stations to a UE, the UE must be notified by some mechanism. Disclosed herein are multiple mechanism for notifying the UE that multiple base stations will be transmitting toe same data at the same time. When there is a backhaul between a TRP and another, each TRP can choose to send the same data stream to increase the reliability of the transmission when, for example, the UE receives at a low signal-to-noise ratio (SNR).

    Abstract: Provided is a reference signal transmission method and device. The method includes that a base station transmits indication information to a UE through a downlink control signaling or a higher layer signaling, where the indication information includes one of: information indicating that the UE transmits a reference signal, information indicating whether the reference signal is contained in a physical downlink shared channel or a physical downlink control channel, or information indicating a transmission mode of a downlink reference signal or an uplink reference signal; or the base station pre-defines with the UE a time-frequency resource or a parameter set required by the UE or the base station to transmit the reference signal, where the time-frequency resource or the parameter set includes at least one of: a time domain symbol position, a frequency domain position, a transmission period and a subframe offset, a type of a reference signal sequence or an orthogonal mask. This solves the problem in the existing art of how to properly place a reference signal on time-frequency resources and trigger a signaling correspondingly.
