Wearable devices can also be called wearable smart devices, which are the general term for the intelligent design of daily wear and the development of wearable devices using wearable technology, such as glasses, gloves, watches, clothing and shoes.

In this embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell, and the cell may be a network device (for example, a frequency domain resource). The cell corresponding to the base station), the cell can belong to the macro base station, or it can belong to the base station corresponding to the small cell (Small cell), where the small cell can include: Metro cell, Micro cell, Pico cell cell), Femto cell, etc. These small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

Before introducing the technical solution of this application, CA will be introduced as follows:

In order to provide a higher system peak rate, it is necessary to provide a maximum transmission bandwidth of 100MHz. However, due to the scarcity of continuous spectrum with such a large bandwidth, CA is proposed, that is, to obtain a larger transmission bandwidth through multiple continuous or non-consecutive carrier aggregation. This results in higher peak rates and throughput. Among them, according to whether the aggregated carriers are continuous in spectrum, it can be divided into continuous carrier aggregation and discontinuous carrier aggregation.

CA is to aggregate 2 or more CCs together to support larger transmission bandwidth (maximum 100MHz). The standard stipulates that a CA aggregates up to 5 CCs, and the aggregated CCs belong to the same network device.

The bandwidth of each CC can be 5MHz, 10MHz, 15MHz and 20MHz, but the maximum bandwidth does not exceed 20MHz. As shown in Figure 2, using the CA technology, two non-consecutive 20MHz CC aggregations can obtain a bandwidth of 40MHz. As shown in Figure 3, using the CA technology, five consecutive 20MHz CC aggregations can obtain a 100MHz bandwidth.

To efficiently utilize fragmented spectrum, CA supports aggregation between different CCs as follows:

(1) CCs of the same or different bandwidths;

(2) Contiguous or non-contiguous CCs within the same frequency band;

(3) CCs in different frequency bands;

According to whether the frequency bands (bands) where the aggregated CCs are located are the same, CA can be divided into intra-band (intra-band) carrier aggregation and inter-band (inter-band) carrier aggregation. .

Basic concepts in CA:

Primary cell (Primary Cell, PCell): It is the cell where the terminal equipment performs initial connection establishment, or the cell for RRC connection reestablishment, or the primary cell designated in the handover process. PCell is responsible for RRC communication with terminal equipment. The CC corresponding to the PCell is called the Primary Component Carrier (PCC). The Physical Uplink Control Channel (PUCCH) exists on the PCC and only exists on the PCC. The downlink carrier of the PCell is called a downlink (Downlink, DL) PCC, and the uplink carrier of the PCell is called an uplink (Uplink, UL) PCC.

Secondary cell (Secondary Cell, SCell): It is added during RRC reconfiguration to provide additional radio resources, and there is no RRC communication between the SCell and the terminal device. The CC corresponding to the SCell is called a secondary carrier (Secondary Component Carrier, SCC). Among them, the downlink carrier of SCell is called DL SCC, and the uplink carrier of SCell is called UL SCC.

PCell is determined at connection establishment. The SCell is added/modified/released through the RRC Connection Reconfiguration message after the initial security activation procedure.

Serving cell: It is a cell that provides services (that is, uplink and downlink transmission) for terminal equipment. If the terminal device is in the RRC connected state (RRC_CONNECTED), but CA is not configured, the terminal device has only one serving cell, namely PCell; if the terminal device is in the RRC_CONNECTED state and CA is configured, the serving cell set of the terminal device includes: PCell and all SCells. That is, the serving cell may refer to both PCell and SCell. A terminal device configured with CA can be connected to 1 PCell and at most 4 SCells. The terminal equipment configured with CA uses the same cell-radio network temporary identifier (Cell-RadioNetworkTemporaryIdentifier, C-RNTI) in all serving cells to ensure that C-RNTI does not conflict in all serving cells.

For any terminal device, each CC (cell) has a corresponding index. The index of the PCell is fixed at 0, and the index of each SCell is specially configured by the network device to the terminal device.

Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, downlink carrier aggregation is required, but uplink carrier aggregation is not required. Moreover, for PCell, there must be PDCCH and PUCCH of this cell, and only PCell has PUCCH, and other secondary cells may have PDCCH.

As described above, the scheduling of each CC in CA is divided into co-carrier scheduling and cross-carrier scheduling according to whether the CC where the PDCCH resource used for scheduling is located and the scheduled CC are the same CC.

The same-carrier scheduling refers to that the PDCCH scheduling of a serving cell is performed on the radio resources of the cell. That is, the scheduling information and the CC used for data transmission are the same CC.

Cross-carrier scheduling refers to allowing the PDCCH of one serving cell to schedule radio resources on another serving cell. That is, scheduling information is transmitted on one CC, and corresponding data is transmitted on another CC. The introduction of cross-carrier scheduling is based on interference avoidance in heterogeneous networks.

Exemplarily, FIG. 4 is a schematic diagram of co-carrier scheduling provided by an embodiment of the present application. As shown in FIG. 4 , the scheduling of each Physical Downlink Shared Channel (PDSCH) is performed through its own CC. of PDCCH scheduling. FIG. 5 is a schematic diagram of cross-carrier scheduling provided by an embodiment of the present application. As shown in FIG. 5 , scheduling of PDSCHs on three CCs is performed through PDCCH scheduling on one CC.

It should be noted that in cross-carrier scheduling, the scheduling information between different CCs is distinguished by the carrier indicator field (Carrier Indicator Field, CIF) in the downlink control information (Downlink Control Information, DCI), and the CIF is used to indicate the number of the CC , fixed at 3 bits, ranging from 0 to 7, where the CIF of PCC is fixed at 0. There may be multiple CCs with PDCCH channels, but PCCs must have their own PDCCH channels. The network device may instruct the current SCC to use the PDCCH channel of which CC for scheduling through high-layer signaling configuration.

As described above, in the prior art, the scheduling method of a CC is either a cross-carrier scheduling method or a same-carrier scheduling method, and the carrier scheduling method is semi-statically configured through RRC signaling. This semi-static RRC signaling configuration carrier scheduling method has the problem of low adaptability.

In order to solve the above technical problems, the present application enables the terminal device to dynamically change or adjust the carrier scheduling method by means of dynamic indication.

The technical solutions of the present application are described in detail below through specific embodiments.

FIG. 6 is an interaction flowchart of a wireless communication method provided by an embodiment of the present application, and the method includes the following steps:

Step S610: The terminal device receives the indication information, where the indication information is used to indicate whether to activate the cross-carrier scheduling mode or the same-carrier scheduling mode of the first serving cell of the terminal device.

It should be understood that, in this application, certain information of a cell may also be referred to as certain information of a CC, where the CC is a CC corresponding to the cell. For example, the carrier scheduling method of the cell may be called the CC scheduling method.

Optionally, the data of the first serving cell may be uplink data or downlink data. When the data of the first serving cell is uplink data, the PDCCH on the second serving cell is used to schedule the data of the first serving cell, It can also be described as: the PDCCH on the second serving cell is used to schedule the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) of the first serving cell. When the data of the first serving cell is downlink data, then the PDCCH on the second serving cell is used to schedule the data of the first serving cell, which can also be described as: the PDCCH on the second serving cell is used to schedule the first serving cell PDSCH of the cell.

Optionally, the scheduling information of the first serving cell may also be described as scheduling information of the PDCCH or DCI of the first serving cell, where the scheduling information is used to schedule data of the first serving cell.

It should be understood that, for the same-carrier scheduling mode, since the scheduling information and the CC used for data transmission are the same CC, the network device does not need to send the configuration information of the same-carrier scheduling mode to the terminal device. However, the terminal device needs to know whether the network device supports the same-carrier scheduling method, or whether it supports the dynamic adjustment of the carrier scheduling method. Wherein, the terminal device can learn whether the network device supports the same-carrier scheduling method or whether it supports the dynamic adjustment of the carrier scheduling method in the following ways, but is not limited to this:

(1) The first configuration information further includes: a first indication. The first indication is used to indicate the same-carrier scheduling mode of the first serving cell supporting the terminal device.

(2) The first configuration information further includes: a second indication. The second indication is used to indicate that the dynamic adjustment of the carrier scheduling mode is supported.

Optionally, the preset bits and preset lengths may be configured by network equipment, and the present application does not limit how to determine the preset bits and preset lengths, and the positions and preset lengths of the preset bits.

Optionally, the preset length may be 1. Correspondingly, the value of the first indication may be 0 or 1. When the value of the first indication is 0, it indicates that the same-carrier scheduling of the first serving cell of the terminal device is supported. Way. Or, when the value of the first indication is 1, it indicates that the same-carrier scheduling mode of the first serving cell of the terminal device is supported.

Optionally, when the first configuration information includes the first indication and the configuration information of the cross-carrier scheduling mode of the first serving cell, it means that the terminal device supports the same-carrier scheduling mode and the cross-carrier scheduling mode of the first serving cell, based on this , the terminal device can dynamically adjust the carrier scheduling mode according to the above indication information.

For item (2):

Optionally, the second indication is at the serving cell level or the terminal device level. That is, the second indication may indicate that the first serving cell supports the dynamic adjustment of the carrier scheduling mode. The above-mentioned terminal equipment may also be instructed to support adjusting the carrier scheduling mode.

Optionally, the second indication may be set on a preset bit of the second dedicated signaling, and the length may be a preset length.

Optionally, the preset length may be 1. Correspondingly, the value of the second indication may be 0 or 1. When the value of the second indication is 0, it indicates that the dynamic adjustment of the carrier scheduling mode is supported. Alternatively, when the value of the first indication is 1, it indicates that the dynamic adjustment of the carrier scheduling mode is supported.

Optionally, when the first configuration information includes the second indication and the configuration information of the cross-carrier scheduling mode of the first serving cell, it means that the terminal device supports the same-carrier scheduling mode and the cross-carrier scheduling mode of the first serving cell, based on this , the terminal device can dynamically adjust the carrier scheduling mode according to the above indication information.

It should be understood that, when the initial default carrier scheduling mode of the first serving cell is the same-carrier scheduling mode, then activating the same-carrier scheduling mode can be understood as using the same-carrier scheduling mode; in the initial default carrier scheduling mode of the first serving cell When it is a cross-carrier scheduling method, then activating the same-carrier scheduling method can be understood as switching the carrier scheduling method to the cross-carrier scheduling method or using the cross-carrier scheduling method; the initial default carrier scheduling method in the first serving cell is the cross-carrier scheduling method. , then activating the same-carrier scheduling method can be understood as switching the carrier scheduling method to the same-carrier scheduling method or using the same-carrier scheduling method; when the initial default carrier scheduling method of the first serving cell is the cross-carrier scheduling method, then activating the cross-carrier scheduling method The carrier scheduling method can be understood as using a cross-carrier scheduling method.

Alternatively, "activation" is relative to "inactive", and the initial default carrier scheduling mode can be understood as the carrier scheduling mode in the inactive state.

It should be noted that the time at which the terminal device receives the indication information is the same as the time at which the cross-carrier scheduling mode or the same-carrier scheduling mode is activated. Alternatively, the time difference between the time when the terminal device receives the indication information and the time when the cross-carrier scheduling mode or the same-carrier scheduling mode is activated is a preset value. For example, the time for the terminal equipment to receive the indication information is n, the time for activating the cross-carrier scheduling mode or the same-carrier scheduling mode is n+k, and k is a preset value.

Optionally, the preset value is configured by the network device, for example, the preset value is configured by the network device through RRC signaling, DCI or MAC CE.

Optionally, in this application, the time unit may be a subframe, a symbol, or a time slot, etc., which is not limited in this application.

To sum up, in this application, the terminal device can determine whether to activate the cross-carrier scheduling mode or the same-carrier scheduling mode of the first serving cell of the terminal device according to the indication information, so as to dynamically adjust the carrier scheduling mode, thereby improving the adaptability of the carrier scheduling mode. To adapt to the cell environment, such as changes in interference, for example: when the interference of the first serving cell is relatively large, the terminal device can activate the cross-carrier scheduling mode to perform data scheduling in other cells. When the interference of the first serving cell is relatively small, the terminal device may activate the same-carrier scheduling mode to perform data scheduling in this cell.

Alternatively, 1 indicates that intra-carrier scheduling is activated, and 0 indicates that cross-carrier scheduling is activated. The number of bits included in the indication information or MAC CE is ceil(n/8)*8, where n is the number of serving cells that support cross-carrier scheduling. ceil() is a round-up function. For example, n=12, and the number of bits included in the MAC CE is Ceil(12/8)*8=16.

For item (3):
