Technical Field

Background

In Long Term Evolution (LTE), a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform is fixedly adopted for a downlink, and a discrete fourier transform spread spectrum Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform is adopted for an uplink.

Detailed Description

The embodiment of the application provides a resource indicating and determining method and device, which are used for determining a frequency diversity mechanism when communication links in the same direction in an NR system simultaneously support a CP-OFDM waveform and a DFT-s-OFDM waveform.

s101, determining a waveform of a physical channel;

the physical channel may be an uplink physical channel or a downlink physical channel. In particular, it may be a channel for transmitting data or control signaling, such as PUSCH/PUCCH.

In the specific implementation manner of this step, for example, the UE may determine that the waveform of the PUSCH/PUCCH is DFT-s-OFDM or CP-OFDM according to the configuration of the network side higher layer signaling or the notification of the physical layer signaling.

S102, determining a Resource Block (RB) mapping mode indicated by an information domain in the scheduling information of the physical channel according to the waveform;

the RB mapping scheme is, for example, a mapping scheme from VRBs, that is, RBs indicated in the scheduling information, to PRBs, that is, RBs used in actual transmission.

S103, determining the RB position of the physical channel according to the RB mapping mode.

As to this step, for example, specifically includes: and if the frequency diversity mode adopts frequency hopping, determining the RB position of the physical channel according to the allocated RB sequence number and the frequency hopping rule. If the frequency diversity mode adopts distributed VRB, the RB position of the physical channel is determined according to the distributed RB sequence and the mapping rule of VRB to physical RB. Otherwise, the RB position of the physical channel corresponds to the allocated RB sequence number one to one.

Optionally, when the waveform is a DFT-s-OFDM waveform, the information field indicates whether to turn on frequency hopping.

Optionally, the VRB type is a centralized VRB or a distributed (i.e., discretized) VRB.

The localized VRBs, for example, refer to the same frequency domain position of one RB in one time unit; the distributed VRBs, for example, refer to different frequency domain locations of an RB in different time periods in a time unit. The time unit may be, for example, a time slot.

Accordingly, referring to fig. 2, on a network side, for example, on a base station side, a resource indication method provided in an embodiment of the present application includes:

s201, determining a waveform of a physical channel;

the physical channel may be an uplink physical channel or a downlink physical channel. In particular, it may be a channel for transmitting data or control signaling.

S202, determining an RB mapping mode of the physical channel according to the waveform;

s203, sending the scheduling information of the physical channel, wherein the information field indicates the RB mapping mode.

Optionally, the waveform is a CP-OFDM waveform, or a DFT-s-OFDM waveform.

Optionally, the RB mapping scheme includes frequency hopping and/or VRB type.

Optionally, when the waveform is a CP-OFDM waveform, the information field indicates whether to turn on frequency hopping and/or VRB type.

Optionally, the VRB type is a centralized VRB or a distributed VRB.

Optionally, the information field occupies 1 bit.

An illustration of specific embodiments is given below.

The first embodiment is as follows:

one information field in the scheduling information is 1 bit, and is used to indicate whether the uplink physical channel (of course, the downlink physical channel) starts frequency hopping or indicates the VRB type. And the UE determines the waveform of the uplink physical channel to be CP-OFDM or DFT-s-OFDM. When the UE determines that the waveform of the uplink physical channel is DFT-s-OFDM, the 1-bit information domain is used for indicating whether the uplink physical channel starts frequency hopping; when the UE determines that the waveform of the uplink physical channel is CP-OFDM, the 1-bit information field is used to indicate that a Virtual Resource Block (VRB) type is a centralized VRB or a distributed VRB.

Example 1.1:

the UE determines that the waveform of the Random Access Channel (RACH) message 3 is DFT-s-OFDM or CP-OFDM according to the notification of the Remaining Minimum System Information (RMSI).

The UE receives a random access response message, which carries a 1-bit information field for use in RACH message 3 grant, for indicating whether RACH message 3 is frequency hopped or for indicating VRB type. Specifically, if the UE determines that the waveform of the RACH message 3 is DFT-s-OFDM, a 1-bit information field in the RACH message 3 grant is used to indicate whether the RACH message 3 starts frequency hopping; if the UE determines that the waveform of the RACH message 3 is CP-OFDM, a 1-bit information field in the RACH message 3 authorization is used for indicating that the VRB type of the RACH message 3 is a centralized VRB or a distributed VRB.

Example 1.2:

a 1-bit Information field in Downlink Control Information (DCI) for allocating uplink data channel PUSCH or uplink Control channel PUCCH resources, for indicating whether PUSCH/PUCCH is frequency hopped or indicating a VRB type. And the UE determines the waveform of the PUSCH/PUCCH as DFT-s-OFDM or CP-OFDM according to the configuration of the network side high-level signaling or the notification of the physical layer signaling. If the UE determines that the waveform of the PUSCH/PUCCH is DFT-s-OFDM, a 1-bit information field of the DCI is used for indicating whether the PUSCH/PUCCH is started for frequency hopping; and if the UE determines that the waveform of the PUSCH/PUCCH is CP-OFDM, a 1-bit information field in the DCI is used for indicating that the VRB type of the PUSCH/PUCCH is a centralized VRB or a distributed VRB.

Example two:

and the UE determines the waveform of the uplink physical channel to be CP-OFDM or DFT-s-OFDM. If the waveform is CP-OFDM, the scheduling information indicates whether the uplink physical channel is frequency hopping and/or VRB type. And if the waveform is DFT-s-OFDM, the scheduling information indicates whether the uplink physical channel hops.

For a waveform being CP-OFDM, specifically, for example, 1 bit is respectively adopted to indicate whether frequency hopping is turned on and a VRB type; or a 2-bit indication is used for whether frequency hopping is carried out and VRB type is jointly coded. Or, the UE determines whether to only indicate frequency hopping or only indicate the VRB type in the scheduling information according to the network side notification. For example, when the network side notifies the UE that the scheduling information only indicates whether to hop frequency, a 1-bit information field in the scheduling information is used to indicate whether to hop frequency of the uplink physical channel; and when the network side informs the UE that the scheduling information only indicates the VRB type, the information field is used for indicating the centralized VRB or the distributed VRB allocation.
