Description

Data communication method and communication device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a data communication method and a communication apparatus.

Background

There may be multiple cells (cells) in a frequency band, where a cell generally includes an UL carrier (UL carrier) and a downlink carrier (DL carrier), and carriers between different cells may be aggregated.

Since each operator has a limited number of frequency bands to assign and is not necessarily contiguous, the UE rate is limited if each User Equipment (UE) can only use a few of the frequency bands. Therefore, the rate of the UE can be increased by Carrier Aggregation (CA), that is, by aggregating carriers in the same frequency band or different frequency bands to the UE, for example, an operator has two frequency bands: band A and Band B, the Band A and the Band B can be simultaneously allocated to the UE for aggregation by using CA technology. It should be noted that, in carrier aggregation, each carrier corresponds to one Cell. Because the uplink CA capability is limited, the downlink can support 8 cells, but the uplink may only support 2 cells, that is, only the carriers corresponding to two cells can be aggregated at most, and at this time, even if the operator has more UL carriers, the carriers cannot be utilized, so that the uplink carrier utilization rate is low.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present disclosure. The communication system may include, but is not limited to, one or more network devices and one or more terminal devices, such as a network device 101 and a terminal device 102 in fig. 1, where the network device 101 in fig. 1 is a base station, the terminal device 102 is a handset, and the terminal device 102 may establish a wireless link with the network device 101 for communication.

In the communication system shown in fig. 1, carriers in different frequency bands are aggregated by Carrier Aggregation (CA) for the terminal device 102, so that the communication rate when the terminal device 102 communicates with the network device 101 can be improved. However, due to the limited uplink CA capability, the following rows may support 8 cells, but the uplink may only support 2 cells, and at this time, even if the operator has more Uplink (UL) carriers, the uplink carriers cannot be utilized, so that the uplink carrier utilization rate is low.

The present application provides a data communication method that can be applied to the communication system shown in fig. 1.

Referring to fig. 2, fig. 2 is a flowchart illustrating a data communication method according to an embodiment of the present application, where the data communication method is applicable to the communication system shown in fig. 1, and is explained from the perspective of interaction between a network device and a terminal device. The data communication method includes the steps of:

s201, the terminal device determines a target uplink UL carrier, where the target UL carrier is determined based on priorities of channels or signals on at least two UL carriers in a target time slot, where the channels or signals on the at least two UL carriers overlap in the target time slot, or the target UL carrier is determined based on target information, where the target information is used to indicate that the terminal device is allowed to switch from at least one first uplink UL carrier to at least one second UL carrier.

In this embodiment, the target UL carrier may include one or more UL carriers, where the terminal device may determine the target UL carrier based on priorities of channels or signals on at least two UL carriers in a target time slot, where the channels or signals on the at least two UL carriers overlap in the target time slot, or the terminal device may also determine the target UL carrier based on target information, where the target information is used to indicate that the terminal device is allowed to switch from at least one first uplink UL carrier to at least one second UL carrier, and the following examples describe a method for determining the target UL carrier by the terminal device:

in the first mode, the terminal device determines the target UL carrier based on the priority of the channels or signals on at least two UL carriers in the target timeslot.

Specifically, optionally, the network device may pre-configure an uplink channel or a signal to be transmitted on a certain UL carrier of a certain timeslot, and in this application, the uplink channel or the signal is referred to as a configured uplink channel or a configured uplink signal. Optionally, the network device may also dynamically schedule an uplink channel or signal to be sent on a certain carrier of a certain timeslot, and in this application, this uplink channel or signal is referred to as a dynamically scheduled or dynamically triggered uplink channel or signal.

For example, as shown in fig. 3, taking slot 1 as an example, the network device dynamically schedules the D-PUCCH to be transmitted on carrier CC0 of slot 1, the network device configures the CG-PUSCH to be transmitted on carrier CC2 of slot 1, and the network device dynamically schedules the a-SRS to be transmitted on carrier CC3 of slot 1. It is understood that uplink channels or signals on different UL carriers in the same slot may be the same or different, and this application is not limited thereto, for example, as shown in slot 2 of fig. 3, CG-PUSCH is configured on each of carriers CC0, CC1, and CC 3.

Specifically, optionally, the terminal device determines a target time slot according to an uplink reference SCS, and if there is overlap of channels or signals on at least two UL carriers in the target time slot and the number of the at least two UL carriers exceeds the transmission capability of the terminal device, the target UL carrier needs to be determined based on the priorities of the channels or signals on the at least two UL carriers in the target time slot. Optionally, the UL carrier with the highest priority of the channels or signals on the at least two UL carriers in the target timeslot may be selected as the target UL carrier.

In some optional embodiments, the priority of the dynamically scheduled or dynamically triggered uplink channel or signal is greater than the priority of the configured uplink channel or signal, that is, the dynamically scheduled or dynamically triggered uplink channel or signal is preferentially selected to be transmitted on the UL carrier. Wherein the configured uplink channel or signal comprises one or more of: a semi-persistent uplink channel or signal, a periodically transmitted uplink channel or signal, an authorized uplink channel or signal. For example, as shown in fig. 3, if the target slot is slot 1, the dynamically scheduled D-PUSSCH and a-SRS have higher priority than the configured CG-PUSCH, and if the transmission capability of the terminal device is 2 ports, i.e. channels or signals on two UL carriers at most are transmitted, the terminal device may select to transmit the D-PUSSCH on carrier CC0 and the a-SRS on carrier CC3 in slot 1.

In some optional embodiments, if, in the target timeslot, the channels or signals on at least two UL carriers are configured uplink channels or signals, the smaller the value of the cell identifier ID corresponding to the UL carrier is, the higher the priority of the configured uplink channel or signal on the UL carrier is. For example, as shown in fig. 3, if the target timeslot is timeslot 2, and CG-PUSCHs are configured on carriers CC0, CC1, and CC2, and if the transmission capability of the terminal device is 2 ports, that is, channels or signals on at most two UL carriers are transmitted, priority determination is performed according to cell identification IDs corresponding to the respective UL carriers, where a cell ID corresponding to the carrier CC0 is smaller than a cell ID corresponding to the carrier CC1, and a cell ID corresponding to the carrier CC1 is smaller than a cell ID corresponding to the carrier CC2, so that the terminal device may select to transmit the CG-PUSCH on the carrier CC0 and the CG-PUSCH on the carrier CC1 in timeslot 2.

It may be understood that, in some scenarios, in the target timeslot, the number of UL carriers of the dynamically scheduled channel or signal may be smaller than the transmission capability of the terminal device, for example, the transmission capability of the terminal device is 2 ports, only 1 UL carrier is a dynamically scheduled uplink channel or signal in the target timeslot, and the remaining UL carriers are configured uplink channels or signals, so that in addition to determining the UL carrier of the dynamically scheduled uplink channel or signal as the target UL carrier, an UL carrier with the highest priority may be selected from the remaining UL carriers which are configured uplink channels or signals as the target UL carrier. For the uplink channel or signal configured on the UL carrier, the smaller the value of the cell identification ID corresponding to the UL carrier is, the higher the priority of the uplink channel or signal configured on the UL carrier is.

It should be noted that, in general, the terminal device does not expect that in the target timeslot, the number of UL carriers of the dynamically scheduled or dynamically triggered uplink channel or signal in the at least two UL carriers exceeds the transmission capability of the terminal device. As shown in fig. 3, if the transmission capability of the terminal device is 2 ports, in time slot 3, all the carriers CC1, CC2, and CC3 are dynamically scheduled uplink channels or signals, the number of UL carriers of the dynamically scheduled uplink channels or signals is 3, and exceeds the transmission capability 2 of the terminal device, the terminal device does not expect this scenario.

By means of the first method, the terminal device may determine a target UL carrier according to priorities of channels or signals on each UL carrier in a certain time slot, and in different time slots, the same or different UL carriers may exist in the target UL carrier determined by the terminal device, thereby implementing switching of UL carriers between different time slots, for example, as shown in fig. 3, the target UL carrier determined by the terminal device in time slot 1 is CC0 and CC3, and the target UL carrier determined in time slot 2 is CC0 and CC1, that is, when going from time slot 1 to time slot 2, the carrier CC3 is switched to the carrier CC1, and by means of carrier switching, the terminal device may utilize more UL carriers, and improve uplink carrier utilization.

In the second mode, the terminal device determines a target UL carrier based on the target information.

Specifically, optionally, the network device may send target information to the terminal device, where the target information is used to indicate that the terminal device is allowed to switch from the at least one first UL carrier to the at least one second UL carrier. In a possible embodiment, the target information may also be used to indicate that the second UL carrier supports carrier switching and to indicate which first UL carriers the terminal device is allowed to switch to the second UL carrier.

The target information may be configuration information configured by the network device through higher layer signaling, or the target information may also be indication information indicated by the network device through physical layer signaling. Correspondingly, the terminal equipment receives the target information and determines a target UL carrier according to the target information.

In some optional embodiments, the target information may be used to indicate that the terminal device is allowed to switch from a certain first UL carrier to a certain second UL carrier, that is, one-to-one, and it may be determined whether the UL carrier used by the terminal device before the switching is the first UL carrier indicated by the target information, and if so, the second UL carrier indicated by the target information may be determined as the target UL carrier.

In some optional embodiments, the target information may also be used to indicate that the terminal device is allowed to switch from at least two first UL carriers to a certain second UL carrier, i.e. many-to-one, for example, the target information may be used to indicate that the terminal device is allowed to switch from carrier 1 or carrier 2 to carrier 3, and it may be further determined whether the UL carrier used by the terminal device before switching belongs to an UL carrier in the at least two first UL carriers indicated by the target information, and if so, the second UL carrier indicated by the target information may be determined as the target UL carrier.

In some optional embodiments, the target information may also be used to indicate that the terminal device is allowed to switch from a certain first UL carrier to at least two second UL carriers, i.e. one-to-many, for example, the target information may be used to indicate that the terminal device is allowed to switch from carrier 1 to carrier 2 or carrier 3, and then determine whether the UL carrier used by the terminal device before the switching is carrier 1, and if so, the terminal device may determine carrier 2 and/or carrier 3 as the target carrier.

In some optional embodiments, the target information may also be used to indicate that the terminal device is allowed to switch from at least two first UL carriers to at least two second UL carriers, i.e. many-to-many.

For example, the target information may be used to indicate that the terminal device is allowed to switch from a first set of carriers to a second set of carriers, the first set of carriers comprising at least one first UL carrier, the second set of carriers comprising at least one second UL carrier. Before the handover, if the UL carrier used by the terminal device is an UL carrier in the first set of carriers, an UL carrier in the second set of carriers may be determined as a target UL carrier.

Illustratively, the target information may also include at least one correspondence relationship, where one correspondence relationship includes at least one first UL carrier and at least one second UL carrier, and the correspondence relationship is used to indicate that the terminal device is allowed to switch from the at least one first UL carrier to the at least one second UL carrier. Further, the target information may further include an index number associated with each corresponding relationship. The network device may instruct the terminal device to switch from the first UL carrier in the target correspondence associated with the target index number to the second UL carrier by sending the target index number to the terminal device.

As illustrated below with reference to fig. 4, the target information may be a table as shown in fig. 4, where the network device may configure the table through a high-layer signaling or indicate the table through a physical layer signaling, and the table includes 5 corresponding relationships, where each corresponding relationship is associated with an index number, and each corresponding relationship includes a first carrier and a second carrier, that is, the terminal device is allowed to switch from the first carrier to the second carrier, for example, if the index number is 0, the terminal device is allowed to switch from carrier 1 to carrier 2, and for example, if the index number is 1, the terminal device is allowed to switch from carrier 2 to carrier 3, and so on.

Further, the network device may indicate the target index number to the terminal device, so as to enable the terminal device to perform carrier switching, as shown in fig. 5, where "01, 02, 03, 04, 05, 06, 07, 08" refers to different timeslots, "1P or 2P" refers to that the terminal device uses several ports to transmit uplink channels or signals, if 1P, the terminal device uses 1 port to transmit uplink channels or signals, and if 2P, the terminal device uses 2 ports to transmit uplink channels or signals. For example, in 01 timeslot, the terminal device uses 1 port to transmit an uplink channel or signal on carrier 1, if the network device wants the terminal device to transmit an uplink channel or signal on 2 ports on timeslot 2, and carrier 2 supports transmission using 2 ports, the network device may transmit index 0 to the terminal device, the terminal device receives index 0, and determines that the second UL carrier corresponding to index 0 is carrier 2 from table four, and then uses carrier 2 to transmit an uplink channel or signal on timeslot 2, thereby implementing switching from carrier 1 to carrier 2 for using more UL carriers.

It can be understood that the terminal device may also determine a target UL carrier to be handed over to according to the target information according to a specific scenario, for example, if the UL carrier used before the terminal device is handed over is carrier 2, the terminal device may be handed over to carrier 3 or carrier 4 according to table four, and therefore, the terminal device may select carrier 3 or carrier 4 as the target UL carrier.

S202, the terminal equipment sends an uplink channel or signal through the target UL carrier.

In the embodiment of the present application, after the terminal device determines the target UL carrier, an uplink channel or signal may be sent through the target UL carrier. For example, if the target UL carrier is determined according to priorities of channels or signals on at least two UL carriers in the target time slot, the terminal device may transmit a target uplink channel or signal through the target UL carrier in the target time slot, where the target uplink channel or signal is an uplink channel or signal configured by the target UL carrier in the target time slot, and/or a dynamically scheduled or dynamically triggered uplink channel or signal.

S203, the network device receives an uplink channel or signal transmitted by the terminal device through the target UL carrier.

In this embodiment, the network device may receive an uplink channel or a signal sent by the terminal device through a target UL carrier, where the target UL carrier may be indicated to the terminal device by the network device, for example, the target UL carrier is indicated by a target index number, which may specifically refer to the specific description in the foregoing embodiment and is not described herein again.

It is to be understood that the carrier switch referred to in the embodiments of the present application may also be referred to as cell switch, and may also be applicable to switch between cells, for example, the target information therein indicates that the terminal device is allowed to switch from at least one first UL carrier to at least one second UL carrier, and may also indicate that the terminal device is allowed to switch from at least one first cell to at least one second cell.

In the embodiment of the application, a target UL carrier for sending an uplink channel or signal can be determined based on priorities of channels or signals on at least two UL carriers in a target timeslot, or a target UL carrier for sending an uplink channel or signal can be determined based on target information, where the target information is used to indicate that terminal equipment is allowed to switch from at least one first UL carrier to at least one second UL carrier, so that uplink carriers for sending uplink channels or signals are flexibly determined, more uplink carriers are effectively utilized, and the utilization rate of the uplink carriers is improved.
