Description

Data communication method and communication device

technical field

The present application relates to the technical field of communication, and in particular to a data communication method and a communication device.

Background technique

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

Since the frequency bands available to each operator are limited and not necessarily continuous, if each user equipment (UE) can only use a few of the frequency bands, the rate of the UE will be limited. Therefore, carrier aggregation (CA) can be used to aggregate carriers of the same frequency band or different frequency bands for UE use, thereby increasing the rate of UE. For example, the operator has two frequency bands: Band A and Band B, then CA technology can be used to assign Band A and Band B to UE aggregation at the same time. It should be noted that during carrier aggregation, each carrier corresponds to a Cell. Due to the limited uplink CA capability, the downlink can support 8 cells, but the uplink may only support 2 cells, that is, the carriers corresponding to the two cells can only be aggregated at most. At this time, even if the operator has more The UL carrier cannot be used, so the utilization rate of the uplink carrier is low.

Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of a communication system provided by an embodiment of the present application. The communication system may include, but is not limited to, one or more network devices and one or more terminal devices. For example, a network device 101 and a terminal device 102 are taken as an example in FIG.

Please refer to Figure 2, Figure 2 is a schematic flow diagram of a data communication method provided by the embodiment of the present application, the data communication method can be applied to the communication system shown in Figure 1, and is explained from the perspective of interaction between network equipment and terminal equipment . The data communication method includes the following steps:

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 the target time slot, and the channels on the at least two UL carriers or Signals overlap in the target time slot, or the target UL carrier is determined based on target information, and 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 first uplink UL carrier Two UL carriers.

In this embodiment of the present application, the target UL carrier may include one or more UL carriers, wherein the terminal device may determine the target UL carrier based on the priorities of channels or signals on at least two UL carriers in the target time slot, and the at least two Channels or signals on the UL carrier overlap within 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, the following example illustrates how the terminal device determines the target UL carrier:

In a first manner, the terminal device determines the target UL carrier based on priorities of channels or signals on at least two UL carriers in the target time slot.

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

For example, as shown in Figure 3, taking time slot 1 as an example, the network device dynamically schedules D-PUCCH to be sent on carrier CC0 in time slot 1, and the network device configures CG-PUSCH to be sent on carrier CC2 in time slot 1, and the network device The dynamically scheduled A-SRS is sent on carrier CC3 in time slot 1. It can be understood that, in the same time slot, the uplink channels or signals on different UL carriers may be the same or different, and this application does not make a limitation. For example, as shown in time slot 2 of FIG. CG-PUSCH.

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

In some optional embodiments, the priority of the uplink channel or signal that is dynamically scheduled or triggered is higher than the priority of the configured uplink channel or signal, that is, the uplink channel or signal that is dynamically scheduled or dynamically triggered on the UL carrier is preferentially selected to send. Wherein, the configured uplink channel or signal includes one or more of the following: semi-persistent uplink channel or signal, periodically sent uplink channel or signal, authorized uplink channel or signal. For example, as shown in Figure 3, if the target time slot is time slot 1, the dynamically scheduled D-PUSSCH and A-SRS have higher priority than the configured CG-PUSCH. If the transmission capability of the terminal device is 2 ports, That is, to transmit channels or signals on two UL carriers at most, the terminal device may choose to transmit the D-PUSSCH on carrier CC0 and the A-SRS on carrier CC3 in time slot 1.

In some optional implementation manners, if in the target time slot, the channels or signals on at least two UL carriers are configured uplink channels or signals, the smaller the value of the cell identity ID corresponding to the UL carrier is, the The configured uplink channel or signal on the UL carrier has a higher priority. For example, as shown in Figure 3, if the target time slot is time slot 2, CG-PUSCH is configured on carriers CC0, CC1, and CC2. If the transmission capability of the terminal device is 2 ports, that is, it can transmit up to two UL carriers The channel or signal on the UL carrier shall be prioritized according to the cell ID corresponding to each UL carrier, where the cell ID corresponding to carrier CC0 is smaller than the cell ID corresponding to carrier CC1, and the cell ID corresponding to carrier CC1 is smaller than the cell corresponding to carrier CC2 ID, therefore, the terminal device can choose to transmit the CG-PUSCH on carrier CC0 and the CG-PUSCH on carrier CC1 in time slot 2.

It can be understood that in some scenarios, in the target time slot, the number of dynamically scheduled channels or UL carriers of the signal may be less than the transmission capability of the terminal device, for example, the transmission capability of the terminal device is 2 ports, and the In a time slot, only one UL carrier is a dynamically scheduled uplink channel or signal, and the remaining UL carriers are all configured uplink channels or signals, then the UL carrier of the dynamically scheduled uplink channel or signal can be determined as the target The UL carrier may also select the UL carrier with the highest priority as the target UL carrier among the remaining UL carriers that are configured uplink channels or signals. Wherein, for the configured uplink channel or signal on the UL carrier, the smaller the value of the cell ID corresponding to the UL carrier, the higher the priority of the configured uplink channel or signal on the UL carrier.

It should be noted that, generally, the terminal device does not expect that in the target time slot, the number of UL carriers of uplink channels or signals dynamically scheduled or dynamically triggered in the at least two UL carriers exceeds the sending capability of the terminal device. As shown in Figure 3, if the transmission capability of the terminal device is 2 ports, in time slot 3, the carriers CC1, CC2, and CC3 are all dynamically scheduled uplink channels or signals, and the dynamically scheduled uplink channels or signals are UL carriers The number is 3, which exceeds the transmission capability of the terminal device by 2, and the terminal device does not expect this scenario to occur.

Through the first method, the terminal device can determine the target UL carrier according to the channel or signal priority of each UL carrier in a certain time slot. In different time slots, the target UL carrier determined by the terminal device can have the same or different UL carrier. Carriers, so as to realize the switching of UL carriers between different time slots. For example, as shown in Figure 3, the target UL carriers determined by the terminal device in time slot 1 are CC0 and CC3, and the target UL carriers determined in time slot 2 It is CC0 and CC1, that is, from time slot 1 to time slot 2, carrier CC3 is switched to carrier CC1. Through carrier switching, terminal equipment can use more UL carriers and improve the utilization rate of uplink carriers.

In a second manner, the terminal device determines the 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 at least one first UL carrier to at least one second UL carrier. In a possible implementation manner, the target information may also be used to indicate that the second UL carrier supports carrier switching, and indicate from 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 high-layer signaling, or the target information may also be indication information indicated by the network device through physical layer signaling. Correspondingly, the terminal device receives the target information, and determines the target UL carrier according to the target information.

In some optional implementation manners, 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. Whether the UL carrier indicated by the target information is the first UL carrier indicated by the target information, and if yes, the second UL carrier indicated by the target information may be determined as the target UL carrier.

In some optional implementation manners, 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, that is, many-to-one. For example, the target information may be used to Indicates that the terminal device is allowed to switch from carrier 1 or carrier 2 to carrier 3, and it can be further judged whether the UL carrier used by the terminal device before the switch belongs to the UL carrier of the at least two first UL carriers indicated by the target information, and if so, it can be Determine the second UL carrier indicated by the target information as the target UL carrier.

In some optional implementation manners, 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, that is, one-to-many. For example, the target information may be used to Indicates that the terminal device is allowed to switch from carrier 1 to carrier 2 or carrier 3, then judge whether the UL carrier used by the terminal device before the switch is carrier 1, if yes, the terminal device can determine carrier 2 and/or carrier 3 as the target carrier .

In some optional implementation manners, 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, that is, many-to-many.

Exemplarily, 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 includes at least one first UL carrier, and the second set of carriers includes at least one second UL carrier carrier. Before the handover, if the UL carrier used by the terminal device is the UL carrier in the first carrier set, the UL carrier in the second carrier set may be determined as the target UL carrier.

Exemplarily, the target information may also include at least one corresponding relationship, one corresponding relationship includes at least one first UL carrier and at least one second UL carrier, and the corresponding relationship is used to indicate that the terminal device is allowed to use the at least one first UL carrier switching to the at least one second UL carrier. Further, the target information may also 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.

The following is an example in conjunction with FIG. 4. The target information can be a table as shown in FIG. 4, and the network device can configure the table through high-level signaling or indicate the table through physical layer signaling. 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 Switching from carrier 1 to carrier 2, for example, if the index number is 1, the terminal device is allowed to switch from carrier 2 to carrier 3, and so on.

Furthermore, the network device may indicate the target index number to the terminal device, so that the terminal device performs carrier switching, as shown in Figure 5, where "01, 02, 03, 04, 05, 06, 07, 08" refer to different "1P or 2P" refers to how many ports the terminal equipment uses to send uplink channels or signals. If it is 1P, the terminal equipment uses one port to send uplink channels or signals. If it is 2P, the terminal equipment uses two ports to send uplink channels or signals. Signal. For example, in time slot 01, the terminal device uses 1 port on carrier 1 to send an uplink channel or signal. If the network device wants the terminal device to use 2 ports to send an uplink channel or signal on time slot 2, and carrier 2 supports the use of 2 ports, the network device can send the index number 0 to the terminal device, the terminal device receives the index number 0, and determines from Table 4 that the second UL carrier corresponding to the index number 0 is carrier 2, then in time slot 2 Carrier 2 is used to send uplink channels or signals, so as to switch from carrier 1 to carrier 2 and utilize more UL carriers.

It can be understood that the terminal device can also determine the target UL carrier to be switched to according to the target information according to the specific scenario. For example, the UL carrier used by the terminal device before switching is carrier 2. According to Table 4, the terminal device can Handover to carrier 3 or carrier 4, therefore, the terminal device can select carrier 3 or carrier 4 as the target UL carrier.

S202. The terminal device 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, it can send an uplink channel or signal through the target UL carrier. Exemplarily, if the target UL carrier is determined according to the priorities of channels or signals on at least two UL carriers in the target time slot, the terminal device may transmit the target uplink channel or 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 the uplink channel or signal sent by the terminal device through the target UL carrier.

In this embodiment of the present application, the network device may receive the uplink channel or signal sent by the terminal device through the target UL carrier, where the target UL carrier may be indicated by the network device to the terminal device, for example, the target UL carrier may be indicated by a target index number For details, reference may be made to the specific descriptions in the foregoing embodiments, and details are not repeated here.

It can be understood that the carrier switching involved in this embodiment of the present application may also be referred to as cell switching, and may also be applicable to switching between cells. Handover to at least one second UL carrier may also indicate that the terminal device is allowed to handover from at least one first cell to at least one second cell.

In the embodiment of the present application, the target UL carrier for sending the uplink channel or signal can be determined based on the priority of channels or signals on at least two UL carriers in the target time slot, or the target for sending the uplink channel or signal can be determined based on target information UL carrier, the target information is used to indicate that the terminal device is allowed to switch from at least one first UL carrier to at least one second UL carrier, so as to flexibly determine the uplink carrier used to send the uplink channel or signal, and effectively use more uplink Carrier, which is beneficial to improve the utilization rate of uplink carrier.
