Definitions

  • the first offset can also indicate a start of the B timeslots or a timeslot within the B timeslots.
  • the one or more SLIVs can include one of the following:
  • NR SCS can range from 15 to 240 kHz, with even greater SCS being considered for future NR releases.
  • an increase in SCS results in a proportionally reduced duration of corresponding time resources (e.g., symbols and slots), which can create various difficulties for resource scheduling in NR networks. This is discussed in more detail below.
  • the maximum carrier bandwidth is directly related to numerology according to 2 m * 50 MHz.
  • Figure 7 shows various exemplary UL-DL arrangements within an NR slot.
  • Figure 7A shows an exemplary DL-only (i.e., no UL transmission) slot with transmission starting in symbol 1, i.e., a “late start.”
  • Figure 7B shows an exemplary “DL-heavy” slot with one UL symbol.
  • this exemplary slot includes guard periods before and after the UL symbol to facilitate change of transmission direction.
  • Figure 7C shows an exemplary “UL-heavy” slot with a single UL symbol that can carry DL control information (i.e., the initial UL symbol, as indicated by a different shading style).
  • Figure 7D shows an exemplary UL-only slot with on-time start in symbol 0, with the initial UL symbol usable to carry DL control information (denoted “UL (D)”).
  • PDSCH and PUSCH can be mapped to middle slots in a slot bundle.
  • Slot structures for PDSCH and PUSCH may be modified from NR Rel-16, e.g., for consistency with DMRS and PDCCH mapping patterns in slot.
  • unused OFDM symbols in the PDCCH and PUCCH slots in a bundle can be allocated to PDSCH or PUSCH.
  • NR Rel-16 does not support multi-slots scheduling for DL transmissions (e.g., PDSCH).
  • TDRA for scheduling of DL resources can employ similar techniques as discussed above with respect to UL resources (e.g., options 1-4).
  • K0 indicating PDSCH offset
  • K1 indicating feedback delay
  • K0 indicating PDSCH offset
  • K1 indicating feedback delay
  • the indicator can be included in a physical downlink control channel (PDCCH) monitoring configuration.
  • PDCCH physical downlink control channel
  • UE 1200 can be configured by execution of instructions, stored on a computer-readable medium, to perform operations corresponding to one or more of the exemplary methods described herein.
  • UE 1200 can include a processor 1210 (also referred to as “processing circuitry”) that can be operably connected to a program memory 1220 and/or a data memory 1230 via a bus 1270 that can comprise parallel address and data buses, serial ports, or other methods and/or structures known to those of ordinary skill in the art.
  • a control interface 1260 of the UE 1200 can take various forms depending on the particular exemplary embodiment of UE 1200 and of the particular interface requirements of other devices that the UE 1200 is intended to communicate with and/or control.
  • the control interface 1260 can comprise an RS-232 interface, aUSB interface, an HDMI interface, a Bluetooth interface, an IEEE (“Firewire”) interface, an I 2 C interface, a PCMCIA interface, or the like.
  • control interface 1260 can comprise an IEEE 802.3 Ethernet interface such as described above.
  • the control interface 1260 can comprise analog interface circuitry including, for example, one or more digital-to-analog converters (DACs) and/or analog-to-digital converters (ADCs).
  • DACs digital-to-analog converters
  • ADCs analog-to-digital converters
  • network node 1300 can include hardware and/or software that configures and/or facilitates network node 1300 to communicate with other network nodes in a RAN, such as with other eNBs, gNBs, ng-eNBs, en-gNBs, IAB nodes, etc.
  • Such hardware and/or software can be part of radio network interface 1340 and/or core network interface 1350, or it can be a separate functional unit (not shown).
  • such hardware and/or software can configure and/or facilitate network node 1300 to communicate with other RAN nodes via the X2 or Xn interfaces, as standardized by 3 GPP.
  • the at least one signal or channel includes a PDSCH or a PUSCH, and DMRS associated with the PDSCH or PUSCH; and receiving or transmitting the at least one signal or channel comprises: during a first portion of a bundled time resource, transmitting PDSCH or receiving PUSCH together with the associated DMRS, and otherwise during the bundled time resource, transmitting PDSCH or receiving PUSCH without an associated DMRS.

Abstract

L'invention concerne, selon certains modes de réalisation, des procédés réalisés par un équipement d'utilisateur (UE). De tels procédés comprennent la transmission ou la réception d'au moins un signal ou canal, avec un réseau sans fil, à l'aide de ressources provenant d'une structure de trame composée de ressources temporelles et de ressources fréquencielles. Les ressources temporelles de la structure de trame sont agencées selon une première granularité, tandis que les ressources temporelles utilisées pour émettre ou recevoir ont une seconde granularité qui est un multiple entier de la première granularité. Cet entier multiple est supérieur à un. D'autres modes de réalisation comportent des procédés complémentaires mis en œuvre par un nœud de réseau dans un réseau sans fil, ainsi que des UE et des nœuds de réseau configurés pour mettre en œuvre de tels procédés.
