The embodiments of the present application relate to the field of mobile communication technologies and, in particular, to a data transmission method and apparatus, a network device and a terminal.
Based on a monitoring result of a physical downlink control channel (PDCCH), the terminal determines whether it needs to receive and parse a physical downlink shared channel (PDSCH) over a specific time-frequency resource. However, when the terminal monitors and receives the PDCCH with a smaller bandwidth for the purpose of energy saving, if the terminal needs to perform data scheduling on a larger bandwidth at this time, it needs to wait until the terminal expands a receiving bandwidth before it can perform effective data reception and other operations. In the above process, analyzing from the perspective of time-domain resource utilization efficiency, it will be found that after PDCCH scheduling and before the user equipment (UE) expands the receiving bandwidth, the base station cannot perform data scheduling for the terminal, and the terminal cannot receive useful data information within this period of time.

Step 201: a base station sends a first downlink control channel in a first sub-band, where the first downlink control channel is configured to schedule data in a first time-domain range, and a frequency-domain range of the scheduled data in the first time-domain range occupies a second sub-band.
In the embodiment of the present application, the type of the base station is not limited. For example, the base station may be an NR base station (i.e. gNB), or the base station may also be an LTE base station (i.e. eNB).
In this embodiment of the present application, the first time-domain range is located after the first downlink control channel. For example, a sending time of the first downlink control channel is t1, and the first time-domain range is t2 to t3, t1≤t2≤t3.
In the embodiment of the present application, the first downlink control channel can schedule a downlink data channel or an uplink data channel in the first time-domain range. Where the downlink data channel is configured to transmit downlink data, and the uplink data channel is configured to transmit uplink data.
In the embodiment of the present application, the frequency-domain range of the scheduled data in the first time-domain range may be changed in time.
Step 202: if the second sub-band exceeds the first sub-band, the base station transmits data based on the first sub-band before a first moment in the first time-domain range and transmits data based on the second sub-band after a second moment in the first time-domain range, where a time interval between the first moment and the second moment is configured for a terminal to adjust a receiving bandwidth, and no data transmission is performed during the time interval.
In the embodiment of the present application, the second sub-band exceeding the first sub-band means that the second sub-band covers the first sub-band and a bandwidth of the second sub-band is larger than a bandwidth of the first sub-band.
In the embodiment of the present application, if the second sub-band exceeds the first sub-band, the base station transmits data based on the first sub-band before the first moment in the first time-domain range and transmits data based on the second sub-band after the second moment in the first time-domain range; where the time interval between the first moment and the second moment is configured for the terminal to adjust the receiving bandwidth, and no data transmission is performed during the time interval.
In the embodiment of the present application, when performing resource mapping for the scheduled data, the base station does not perform mapping for a downlink data channel at a first time-frequency resource position. Alternatively, when performing resource mapping for the scheduled data, the base station performs mapping for the downlink data channel at the first time-frequency resource position, but the base station does not perform data sending at the first time-frequency resource position. Further, the first time-frequency resource position refers to a time-frequency resource position before the first moment in the first time-domain range and within the second sub-band but outside the first sub-band.
In the embodiment of the present application, the first downlink control channel is configured to schedule data in the first time-domain range, including:
The technical solution in the embodiment of the present application will be illustrated by examples below with reference to
Referring to
For a time-frequency resource position corresponding to a time-domain position before the first moment in the above-mentioned specific time-domain range and a frequency-domain position within the second sub-band but outside the first sub-band, when performing resource mapping for the scheduled data, the base station does not perform PDSCH mapping at the above-mentioned time-frequency resource position, which means that the above-mentioned resource is taken as an unavailable resource for PDSCH resource mapping. Or, for the time-frequency resource position corresponding to the time-domain position before the first moment in the above-mentioned specific time-domain range and the frequency-domain position within the second sub-band but outside the first sub-band, when performing resource mapping for the scheduled data, the base station performs PDSCH mapping at the above-mentioned time-frequency resource position, but the base station does not perform data sending over the above-mentioned time-frequency resource during actual transmission.
Referring to
For a time-frequency resource position corresponding to a time-domain position before the first moment in the above-mentioned specific time-domain range and a frequency-domain position within the second sub-band but outside the first sub-band, when performing resource mapping for the scheduled data, the base station does not perform PDSCH mapping at the above-mentioned time-frequency resource position, which means that the above-mentioned resource is taken as an unavailable resource for PDSCH resource mapping. Or, for the time-frequency resource position corresponding to the time-domain position before the first moment in the above-mentioned specific time-domain range and the frequency-domain position within the second sub-band but outside the first sub-band, when performing resource mapping for the scheduled data, the base station performs PDSCH mapping at the above-mentioned time-frequency resource position, but the base station does not perform data sending over the above-mentioned time-frequency resource during actual transmission.
In the technical solution of the embodiment of the present application, the base station transmits the PDCCH in the first sub-band. When the PDCCH schedules, in a specific time-domain range, a PDSCH which exceeds the bandwidth of the first sub-band, the base station transmits data based on the first sub-band before a specific first moment in the specific time-domain range, and the base station transmits data based on the second sub-band after a specific second moment in the specific time-domain range.
In the above-mentioned solution, the base station determines the first moment and/or the second moment based on first configuration information. Specifically, a case where the first downlink control channel schedules data in the first time-domain range within one or more time slots is:
For example: the base station transmits the PDCCH in the first sub-band (such as 10 MHz). When the PDCCH schedules data in a specific time-domain range within one or more time slots, the first sub-band is taken as the sending bandwidth before the k1 moment which is after the PDCCH, and the second sub-band is started to be taken as the sending bandwidth at the k2 moment which is after the PDCCH. Where k1 and k2 may be in a unit of absolute time, such as microseconds. Or k1 and k2 may be in a unit of time slot or symbol.
For example: the base station transmits the PDCCH in the first sub-band (such as 10 MHz). When the PDCCH schedules data in a specific time-domain range within multiple time slots, the first sub-band is taken as the sending bandwidth in the first time slot, and the second sub-band is taken as the sending bandwidth after the first time slot.
In the above-mentioned solution, the first configuration information is notified to the terminal through a broadcast message, or radio resource control (RRC) dedicated signaling, or downlink control information (DCI); or, the first configuration information is agreed in a protocol.
In the above-mentioned solution of the embodiment of the present application, the first moment and the second moment are coincident; or, the first moment is not later than the second moment.
Further, the base station selects one type of first configuration information that matches a capability of the terminal from multiple types of first configuration information to determine the first moment and/or the second moment. Here, the first configuration information may be default configuration information.
Step 301: a terminal monitors a first downlink control channel in a first sub-band, where the first downlink control channel is configured to schedule data in a first time-domain range, and a frequency-domain range of the scheduled data in the first time-domain range occupies the second sub-band.
In the embodiment of the present application, the terminal may be any device capable of communicating with a network, such as a mobile phone, a vehicle-mounted terminal, a tablet computer, and a notebook.
In the embodiment of the present application, the first time-domain range is located after the first downlink control channel. For example, the transmission time of the first downlink control channel is t1, and the first time-domain range is t2 to t3, t1≤t2≤t3.
In the embodiment of the present application, the first downlink control channel can schedule a downlink data channel or an uplink data channel in the first time-domain range. Where the downlink data channel is configured to transmit downlink data, and the uplink data channel is configured to transmit uplink data.
In the embodiment of the present application, the frequency-domain range of the scheduled data in the first time-domain range may be changed in time.
Step 302: if the second sub-band exceeds the first sub-band, the terminal receives data based on the first sub-band before a first moment in the first time-domain range and receives data based on the second sub-band after a second moment in the first time-domain range, where a time interval between the first moment and the second moment is configured for the terminal to adjust a receiving bandwidth, and no data reception is performed during the time interval.
In the embodiment of the present application, the second sub-band exceeding the first sub-band means that the second sub-band covers the sub-band and a bandwidth of the second sub-band is larger than a bandwidth of the first sub-band.
In the embodiment of the present application, if the second sub-band exceeds the first sub-band, the terminal receives data based on the first sub-band before the first moment in the first time-domain range and receives data based on the second sub-band after the second moment in the first time-domain range; where the time interval between the first moment and the second moment is configured for the terminal to adjust the receiving bandwidth, and no data reception is performed during the time interval.
In the embodiment of the present application, the terminal determines that when the base station performs resource mapping for the scheduled data, the base station does not perform mapping for a downlink data channel at a first time-frequency resource position, the first time-frequency resource position refers to a time-frequency resource position before the first moment in the first time-domain range and within the second sub-band but outside the first sub-band. Alternatively, the terminal determines that when the base station performs resource mapping for the scheduled data, the base station performs mapping for the downlink data channel at a first time-frequency resource position, but the base station does not perform data sending at the first time-frequency resource position. The first time-frequency resource position refers to a time-frequency resource position before the first moment in the first time-domain range and within the second sub-band but outside the first sub-band.
In the embodiment of the present application, the first downlink control channel is configured to schedule data in the first time-domain range, including:
The technical solution in the embodiments of the present application will be illustrated by examples below with reference to
Referring to
For a time-frequency resource position corresponding to a time-domain position before the first moment in the above-mentioned specific time-domain range and a frequency-domain position within the second sub-band but outside the first sub-band, the UE believes that when the base station performs resource mapping for the scheduled data, the base station does not perform PDSCH mapping at the above-mentioned time-frequency resource position, which means that the above-mentioned resource is taken as an unavailable resource for PDSCH resource mapping. Or, for the time-frequency resource position corresponding to the time-domain position before the first moment in the above-mentioned specific time-domain range and the frequency-domain position within the second sub-band but outside the first sub-band, the UE believes that when the base station performs resource mapping for the scheduled data, the base station performs PDSCH mapping at the above-mentioned time-frequency resource position, but the base station does not perform data sending over the above-mentioned time-frequency resource during actual transmission.
Referring to
For a time-frequency resource position corresponding to a time-domain position before the first moment in the above-mentioned specific time-domain range and a frequency-domain position within the second sub-band but outside the first sub-band, in the process of data reception and parsing, the UE believes that when the base station performs resource mapping for the scheduled data, the base station does not perform PDSCH mapping at the above-mentioned time-frequency resource position, which means that the above-mentioned resource is taken as an unavailable resource for PDSCH resource mapping. Or, for the time-frequency resource position corresponding to the time-domain position before the first moment in the above-mentioned specific time-domain range and the frequency-domain position within the second sub-band but outside the first sub-band, in the process of data reception and parsing, the UE believes that when the base station performs resource mapping for the scheduled data, the base station performs PDSCH mapping at the above-mentioned time-frequency resource position, but the base station does not perform data sending over the above-mentioned time-frequency resource during actual transmission.
In the technical solution of the embodiment of the present application, the UE monitors the PDCCH in the first sub-band. When the UE monitors the PDCCH and finds, based on the parsing of the PDCCH, that it needs to receive in the specific time-domain range a corresponding PDSCH which exceeds the bandwidth of the first sub-band, the UE receives the PDSCH based on the first sub-band before the first moment in the specific time-domain range, and the UE receives the PDSCH based on the second sub-band after the second moment in the specific time-domain range.
In the above-mentioned solution, the terminal determines the first sub-band and/or the second sub-band through a broadcast message, or RRC dedicated signaling, or DCI.
In the above-mentioned solution, the terminal determines the first moment and/or the second moment based on the first configuration information. Further, the terminal may acquire the first configuration information in the following two ways:
Specifically, the implementation of the first configuration information is as follows:
For example: the UE receives the PDCCH in the first sub-band (such as 10 MHz). When the PDCCH schedules data in the specific time-domain range within one or more time slots, the first sub-band is taken as the receiving bandwidth before the k1 moment which is after the PDCCH, and the second sub-band is started to be taken as the receiving bandwidth at the k2 moment which is after the PDCCH. Where k1 and k2 may be in a unit of absolute time, such as microseconds. Or k1 and k2 may be in a unit of time slot or symbol.
For example: the UE monitors the PDCCH in the first sub-band (such as 10 MHz). When the PDCCH schedules data in a specific time-domain range within multiple time slots, the first sub-band is taken as the receiving bandwidth in the first time slot, and the second sub-band is taken as the receiving bandwidth after the first time slot.
In the above-mentioned solution of the embodiment of the present application, the first moment and the second moment are coincident; or, the first moment is not later than the second moment.
Further, the terminal selects one type of first configuration information that matches a capability of the terminal from multiple types of first configuration information to determine the first moment and/or the second moment.
