## Abstract

In one aspect a wireless communications method is disclosed. The method includes transmitting, from a first radio terminal to a second radio terminal, control information or payload data, wherein the receiving and a preparation is completed at a first time. The method further includes receiving, from the second radio terminal, feedback information at an interval later than a last symbol of the transmitted control information or payload data, wherein the interval is pre-defined by a protocol or configured by a network parameter.

## Claims

### Claim 1

A wireless communications method, comprising:
transmitting, from a first radio terminal to a second radio terminal, a first radio control channel information;
transmitting, from the first radio terminal to the second radio terminal, (a) a second radio control channel information, or (b) the second radio control channel information and a data channel; and
receiving, by the first radio terminal from the second radio terminal, feedback information or a shared channel at an interval later than a last symbol of the second radio control channel information or the data channel, wherein the interval is determined according to the first radio control information and the second radio control information.

### Claim 2 (depends on 1)

The wireless communications method of claim 1,
wherein the first radio control channel information includes one or more values for one or more parameters; and
wherein the second radio control channel information excludes the one or more parameters or includes the one or more values.

### Claim 3 (depends on 2)

The wireless communications method of claim 2, wherein the one or more parameters include a modulation and coding scheme (MCS) for the shared channel.

### Claim 4 (depends on 2)

The wireless communications method of claim 2, wherein the one or more parameters includes a redundancy version (RV).

### Claim 5 (depends on 2)

The wireless communications method of claim 2, wherein the one or more parameters includes precoding and a number of layers.

### Claim 6 (depends on 2)

The wireless communications method of claim 2, wherein the one or more parameters includes a resource size allocated to the shared channel.

### Claim 7 (depends on 6)

The wireless communications method of claim 6, wherein the shared channel is a physical uplink shared channel (PUSCH).

### Claim 8 (depends on 1)

The wireless communications method of claim 1, wherein the first radio control channel information or the second radio control channel information is in a physical downlink control channel (PDCCH).

### Claim 9 (depends on 1)

The wireless communications method of claim 1, wherein the first radio control channel is a radio resource control (RRC) signaling.

### Claim 10 (depends on 1)

The wireless communications method of claim 1,
wherein the first control channel information indicates resource information for resources available for transmitting the second radio control channel information.

### Claim 11 (depends on 10)

The wireless communications method of claim 10, wherein the resource information includes a time-frequency resource.

### Claim 12 (depends on 10)

The wireless communications method of claim 10, wherein the resource information includes candidate control channel information.

### Claim 13 (depends on 10)

The wireless communications method of claim 10, wherein the resource information includes control channel element (CCE) resource information.

### Claim 14 (depends on 10)

The wireless communications method of claim 10, wherein the resource information includes resource element group (REG) information.

### Claim 15

A wireless communications method, comprising:
receiving, at a second radio terminal from a first radio terminal, a first radio control channel information;
receiving, at the second radio terminal from the first radio terminal, (a) a second radio control channel information, or (b) the second radio control channel information and a data channel; and
transmitting, from the second radio terminal to the first radio terminal, feedback information or a shared channel at an interval later than a last symbol of the received second radio control channel information or the data channel or payload data, wherein the interval is determined according to the first radio control channel information and the second radio control channel information.

### Claim 16 (depends on 15)

The wireless communications method of claim 15,
wherein the first radio control channel information includes one or more values for one or more parameters; and
wherein the second radio control channel information excludes the one or more parameters or includes the one or more values.
