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 its 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:

allocate uplink control information in a first container, the first container comprising, within a time-frequency resource grid, an allocation for uplink and downlink resources; and

transmit an indication of the first configuration through radio resource control, medium access control element updates, or downlink control information,

wherein the indication of the first configuration is an index into a set of predefined container configurations.

2. The apparatus of claim 1, wherein information in the first container configures resources for multiple subsequent containers.

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

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

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

6. The apparatus of claim 1, wherein the first container contains universal reference signal mapping adjacent to uplink control information to provide detection of 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, and coding derivation information.

8. An apparatus comprising a processor, a memory, and communication circuitry, the apparatus being connected to a communications network via its 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 an indication of a first container, the first container comprising, within a time-frequency resource grid, an allocation for uplink and downlink resources, wherein the indication of the first configuration is an index into a set of predefined container configurations; and

derive resource mapping for uplink control information implicitly from the first container.

9. The apparatus of claim 8, wherein the computer-executable instructions further cause the apparatus to derivation of the modulation and coding for ACK/NACK and soft information on reliability implicitly from the first container.

10. The apparatus of claim 8, wherein the computer-executable instructions further cause the apparatus to jointly encode or bundle ACK/NACK and soft information on reliability.

11. The apparatus of claim 8, wherein the first container further comprises uplink control signaling in separate reserved frequency resources.

12. The apparatus of claim 11, wherein the separate reserved frequency resources are in band edges.

13. The apparatus of claim 8, wherein the computer-executable instructions further cause the apparatus to jointly encode a scheduling request with an ACK/NACK.

14. A method, comprising:

allocating uplink control information in a first container, the first container comprising, within a time-frequency resource grid, an allocation for uplink and downlink resources; and

transmitting an indication of the first configuration through radio resource control, medium access control element updates, or downlink control information,

wherein the indication of the first configuration is an index into a set of predefined container configurations.
