  • the second part of the DL control channel payload is transmitted without occupying any REs for DL data.
  • the second part of the DL control channel payload replaces a comb of the data channel pilot REs of the first pilot symbol of the DL data channel. Rate matching to the comb may result in lower code rate for the second part of the DL control channel payload.

  • QPSK quadrature phase shift keying
  • the diagonal matrix D l may be used to differentiate layers (or antenna ports) and may be generated using either Walsh codes or phase ramping vectors.

  • the diagonal channel matrix D H, r, l may capture potential network node beamforming for layer l and its equivalent physical channel in frequency domain.
  • the same pilot vector p may be common to all L layers.

  • a data model for the second part of the DL control channel payload may be represented as follows: where a QPSK channel vector c may be employed in place of the pilot vector p to carry the second part of the DL control channel payload. After successfully decoding the DL control channel, the channel vector c may be utilized as additional known pilots for the DL data channel. The difference between D H, r, l and may be that they correspond to different but nearby REs. The original data pilot and the second part of the DL control channel payload based pilot are exampled in FIGs. 2 to 4.

  • the second part of the DL control channel payload when there is only the second part of the DL control channel payload in a slot, the second part of the DL control channel payload may be transmitted in the same symbol (s) as the first part of the DL control channel payload. In other words, the second part of the DL control channel payload may be transmitted in one or more symbols used for the first part of the DL control channel payload.
  • the second part of the DL control channel payload may be still needed at times. For example, the second part of the DL control channel payload may still be needed to carry UL data scheduling information or group common DL control messages.

  • the first part and the second part of the DL control channel payload may be multiplexed without DL data channel.
  • Such a multiplexed pattern may enable the UE to enter power saving mode quickly after control processing.
  • better separation of control and data regions may enable cleaner noise estimation for certain UEs connected to a nearby cell, where the signal from the nearby cell may act as interference.
  • the UE may re-encode the second part of the DL control channel payload to generate an additional pilot. More specifically, after decoding the second part of the DL control channel payload, the UE may reencode the second part of the DL control channel payload to generate its corresponding QPSK channel symbol vector, and then the UE may treat reencoded channel vector as the additional pilot for the DL data channel.
  • the UE may estimate a DL channel based on an original pilot and the additional pilot.
  • both the original pilot and the additional pilot based on the DL control channel payload may be designed with the same structure to facilitate unified and low complexity channel estimations for both control of the second part of the DL control channel payload and data demodulations.
  • the first part of the DL control channel payload may include resource information of the second part of the DL control channel payload.
