Abstract

Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes.

Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control.

Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).

Claims

1. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a communications network via the communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to:

determine a first configuration, the first configuration pertaining to a first container within a time-frequency resource grid, the first configuration comprising an allocation for each of uplink control information, downlink data, related reference signals, and uplink ACK/NACK; and

transmit a configuration of the first container through radio resource control, medium access control element updates, or downlink control information.

2. The apparatus of claim 1, wherein the downlink control information in the first configuration further indicates resources for multiple subsequent containers.

3. The apparatus of claim 2, wherein one or more of the subsequent containers provide for a multiplexing of uplink control information for multiple user equipments through time, frequency, or code-division multiplexing.

4. The apparatus of claim 1, wherein the first configuration provides for a multiplexing of uplink control information for multiple user equipments through time, frequency, or code-division multiplexing.

5. The apparatus of claim 1, wherein the first configuration further comprises support for frequency hopping of the uplink control information and a reference signal.

6. The apparatus of claim 1, wherein the first container further comprises a reference signal mapping adjacent to the uplink control information to provide high quality detection of the uplink control information.

7. The apparatus of claim 1, wherein the computer-executable instructions further cause the apparatus to jointly encode uplink control information associated with channel quality estimation, implicit modulation, or coding derivation.

8. The apparatus of claim 1, wherein the first configuration comprises a provision for multiple uplink or downlink transmission time intervals of variable duration.

9. The apparatus of claim 2, wherein multiple configurations of multiple subsequent containers are configured identically with the first configuration.

10. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a communications network via the communication circuitry, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to:

receive, via radio resource control, medium access control element updates, or downlink control information, a first configuration, the first configuration pertaining to a first container within a time-frequency resource grid, the first configuration comprising an allocation for each of uplink control information, downlink data, related reference signals, and uplink ACK/NACK, the first container further comprising support from frequency hopping of the uplink control information; and

communicate via the communication circuitry within the first container according to the first configuration.

11. The apparatus of claim 10, wherein the first configuration further comprises information for multiple subsequent containers.

12. The apparatus of claim 11, wherein multiple configurations of the multiple subsequent containers are configured identically with the first configuration of the first container.
