Definitions

  • a hybrid UE 115-a may communicate with access point 105 -a on both a first hierarchical layer that supports first layer transmissions using a first TTI (also referred to herein as “legacy communications” or “legacy wireless technology”) and a second hierarchical layer that supports second layer transmissions using a second TTI, which may be shorter than the first TTI (also referred to herein as "ULL communications” or “lower latency wireless technology”).
  • first TTI also referred to herein as “legacy communications” or “legacy wireless technology”
  • second TTI which may be shorter than the first TTI
  • a macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 1 15 with service subscriptions with the network provider.
  • a small cell may cover a relatively smaller geographic area and may allow unrestricted access by UEs 115 with service subscriptions with the network provider, for example, and in addition to unrestricted access, may also provide restricted access by UEs 115 having an association with the small cell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the home, and the like).
  • An eNB for a macro cell may be referred to as a macro eNB.
  • An eNB for a small cell may be referred to as a small cell eNB.
  • An eNB may support one or multiple (e.g., two, three, four, and the like) cells.
  • eNBs 204 may include a symbol processing component 302 configured to decode a combined reference signal and control data signal transmission received in a single symbol, or other duration less than a subframe, from one or more UEs 206, as described further herein.
  • UEs 206 may include a communicating component 361 configured to generate a combined reference signal and control data signal for transmitting over a single symbol, or other duration less than a subframe, to the eNB(s) 204/208.
  • the eNBs 204 are responsible for all radio related functions including radio bearer control, admission control, mobility control, scheduling, security, and connectivity to one or more components of core network 130.
  • FIG. 5 illustrates an example system 500 for communicating combined reference and control data signals over a resource block in a single symbol duration.
  • System 500 includes a UE 502 that communicates with an eNB 504 to access a wireless network, examples of which are described in FIGs. 1-3 (e.g., access points 105, eNB 204, 208, eNB 310, UEs 115, 206, 350, etc.), above.
  • control data determining component 522 may include hardware (e.g., one or more processor modules of the one or more processors 553) and/or computer-readable code or instructions stored in memory 555 and executable by at least one of the one or more processors 553 to perform the specially configured control data determining operations described herein.
  • waveform generating component 510 may phase offset the reference signal and control data signal based on selected phase offsets defined for a radio access technology, as described below, such that the difference between the selected phase offsets is even and not equal to zero.
  • waveform generating component 510 may select a phase offset (also referred to as cyclic shift) for each of the reference signal and the control data signal from a set of available phase offsets defined for a corresponding RAT (e.g., LTE).
  • a phase offset also referred to as cyclic shift
  • Using a different phase offset can allow a receiver of the combined signal 580 to differentiate the reference signal and the control data signal (e.g., by performing an IFFT, inverse discrete Fourier transform IDFT, etc.
  • waveform generating component 510 can receive or otherwise generate a QPSK constellation, 16-QAM, etc. representative of the control data, which can represent a 2 bit transmission.
  • the 2 bits can correspond to HARQ feedback for downlink communications received at the UE 502 (e.g., from the eNB 504), and/or other control data that can occupy the 2 bits.
  • waveform generating component 510 can generate the reference signal as the base sequence and the control data signal as the base sequence combined with the QPSK constellation, 16-QAM, etc.
  • eNB 504 may receive a second instance of the signal from the device in a subsequent TTI over a different resource block.
  • symbol processing component 302 can, e.g., in conjunction with one or more processors 553 and/or memory 555, transceiver 556, etc., receive a second instance of the signal from the device (e.g., UE 502) in a subsequent TTI over a different resource block (relative to the resource block used by the first instance of the signal).
  • the subsequent TTI can be an adjacent TTI (e.g., TTI 5 in FIG. 4 where the first instance of the signal is transmitted on TTI 4). This can provide frequency diversity for communicating the signal.
