Technical Field

Background

Carrier Aggregation (CA) enables a New wireless (New Radio, NR) system to support a larger bandwidth by jointly scheduling and using resources on a plurality of Carrier units (CCs), thereby enabling a higher system peak rate. In CA, regarding scheduling of each CC, according to whether a CC where a Physical Downlink Control Channel (PDCCH) resource used for scheduling is located and a scheduled CC are the same CC, the scheduling is divided into common carrier scheduling and cross-carrier scheduling.

In the prior art, a scheduling manner of one CC is either a cross-carrier scheduling manner or a same-carrier scheduling manner, and the carrier scheduling manner is semi-statically configured through Radio Resource Control (RRC) signaling. The reason for employing cross-carrier scheduling is that since the PDCCH of the current serving cell of the terminal device is interfered, scheduling is performed using the PDCCH of another cell. However, since the interference experienced by one cell is not necessarily stable, the above-mentioned method of configuring the carrier scheduling by the RRC signaling semi-static method has a problem of low adaptivity.

In this embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), micro cells (Micro cells), pico cells (Pico cells), femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

Before the technical scheme of the application is introduced, CA is introduced as follows:

in order to provide higher peak rate of the system, it is necessary to provide a transmission bandwidth of maximum 100MHz, but due to the scarcity of continuous spectrum of such a large bandwidth, CA is proposed, that is, a larger transmission bandwidth is obtained by aggregation of multiple continuous or non-continuous carriers, thereby obtaining higher peak rate and throughput. The aggregation may be divided into continuous carrier aggregation and non-continuous carrier aggregation according to whether the aggregated carriers are continuous in the frequency spectrum.

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

The bandwidth of each CC may be 5MHz, 10MHz, 15MHz, and 20MHz, but the maximum bandwidth does not exceed 20MHz. As shown in fig. 2, 2 non-continuous CC aggregation of 20MHz can obtain a bandwidth of 40MHz by using CA technology, and as shown in fig. 3, 5 continuous CC aggregation of 20MHz can obtain a bandwidth of 100MHz by using CA technology.

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

(1) CCs of the same or different bandwidths;

(2) Adjacent or non-adjacent CCs within the same frequency band;

(3) CC in different frequency bands;

CA may be divided into Intra-band (Intra-band) carrier aggregation and inter-band (inter-band) carrier aggregation according to whether bands (bands) in which aggregated CCs are located are the same. .

Basic concepts in CA:

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

Secondary Cell (SCell): it is added at RRC reconfiguration to provide additional radio resources, there is no RRC communication between SCell and terminal device. The CC corresponding to the SCell is referred to as a Secondary Carrier (SCC). Here, a downlink carrier of the SCell is referred to as a DL SCC, and an uplink carrier of the SCell is referred to as an UL SCC.

The PCell is determined at the time of connection establishment (connection establishment). The SCell is added/modified/released by an RRC Connection Reconfiguration message (RRC Connection Reconfiguration) after an initial security activation procedure (initial security activation procedure).

Serving cell: are cells that provide service (i.e., uplink and downlink transmissions) for terminal devices. If the terminal device is in an RRC CONNECTED state (RRC _ CONNECTED) but CA is not configured, the terminal device has only one serving cell, i.e., PCell; if the terminal device is in RRC _ CONNECTED state and CA is configured, the serving cell set of the terminal device includes the PCell and all scells. That is, the serving cell may be referred to as a PCell or an SCell. A CA-configured terminal device may be connected to 1 PCell and up to 4 scells. The terminal device configured with the CA uses the same Cell-radio network temporary identifier (C-RNTI) in all serving cells to ensure that the C-RNTI does not conflict in all serving cells.

For any one terminal device, there is a corresponding index for each CC (cell). The index of the PCell is fixed to 0, while the index of each SCell is specifically configured by the network device to the terminal device.

Because the asymmetric carrier aggregation and the symmetric carrier aggregation are supported, downlink carrier aggregation is required to be performed, and uplink carrier aggregation can be avoided. And for the PCell, the PDCCH and the PUCCH of the cell are required to exist, only the PCell has the PUCCH, and other secondary cells may have the PDCCH.

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

The co-carrier scheduling refers to that the PDCCH scheduling of one serving cell is performed on radio resources in the cell. I.e. the scheduling information and the CC used for data transmission are the same CC.

Cross-carrier scheduling refers to allowing a PDCCH of one serving cell to schedule radio resources on another serving cell. I.e. scheduling information is transmitted on one CC and corresponding data is transmitted on another CC. The introduction of cross-carrier scheduling is heterogeneous network based interference avoidance.

For example, fig. 4 is a schematic diagram of the same-carrier scheduling provided in an embodiment of the present application, and as shown in fig. 4, scheduling of each Physical Downlink Shared Channel (PDSCH) is scheduled through a PDCCH on a CC where the PDSCH is located. Fig. 5 is a schematic diagram of cross-carrier scheduling according to an embodiment of the present application, and as shown in fig. 5, the PDSCH on all three CCs is scheduled through the PDCCH on one CC.

It should be noted that, in cross-Carrier scheduling, scheduling Information between different CCs is distinguished by a Carrier Indicator Field (CIF) in Downlink Control Information (DCI), the CIF is used to indicate the number of the CC, and 3 bits are fixed, and values are 0 to 7, where the CIF of the PCC is fixed to 0. There may be multiple CCs on which PDCCH channels exist, but a PCC must have its own PDCCH channel. The network device may indicate which CC's PDCCH channel is used by the current SCC for scheduling through a high layer signaling configuration.

As described above, in the prior art, the scheduling manner of one CC is either a cross-carrier scheduling manner or a same-carrier scheduling manner, and the carrier scheduling manner is configured semi-statically through RRC signaling. The problem of low adaptivity exists in the carrier scheduling mode configured in the RRC signaling semi-static mode.

In order to solve the technical problem, the terminal device can dynamically change or adjust the carrier scheduling mode in a dynamic indication mode.

The technical solution of the present application is described in detail by specific examples below.

Fig. 6 is an interaction flowchart of a wireless communication method according to an embodiment of the present application, where the method includes the following steps:

step S610: the terminal equipment receives indication information, wherein the indication information is used for indicating whether a cross-carrier scheduling mode or a same-carrier scheduling mode of a first service cell of the terminal equipment is activated.

It should be understood that, in the present 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 of the cell may be referred to as a scheduling of CCs.

Optionally, the network device may configure an initial default carrier scheduling manner of the first serving cell for the first serving cell through the first dedicated signaling.

Alternatively, the first dedicated signaling may be RRC signaling, DCI, or a Media Access Control Element (MAC CE).

In this application, after the terminal device enters the RRC _ CONNECTED state, the network device may send first configuration information to the terminal device, where the first configuration information includes: and configuration information of a cross-carrier scheduling mode of a first serving cell of the terminal equipment.

Alternatively, the network device may send the first configuration information through second dedicated signaling.

Optionally, the second dedicated signaling may be RRC signaling, DCI signaling, or MAC CE.

Optionally, the first serving cell is also described as a current serving cell of the terminal device.

Optionally, the first serving cell is a PCell or an SCell of the terminal device.

Optionally, the configuration information of the cross-carrier scheduling manner includes: an Identity (ID) of the second serving cell and a CIF in scheduling information of the first serving cell. Wherein the second serving cell is used for scheduling the first serving cell. I.e. the PDCCH on the second serving cell is used for scheduling data of the first serving cell.

Optionally, the data of the first serving cell may be uplink data or downlink data, and 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, which may also be described as: the PDCCH on the second serving cell is used to schedule a 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 may also be described as: the PDCCH on the second serving cell is used to schedule the PDSCH of the first serving cell.

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

It should be understood that, for the same-carrier scheduling manner, 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 manner for the terminal device. However, the terminal device needs to know whether the network device supports the same carrier scheduling manner or whether the network device supports the dynamic adjustment carrier scheduling manner. The terminal device may learn whether the network device supports the same carrier scheduling mode or whether the network device supports the dynamic adjustment carrier scheduling mode, but is not limited to this:

(1) The first configuration information further includes: a first indication. The first indication is used for indicating a same-carrier scheduling mode of a first service cell supporting the terminal equipment.

(2) The first configuration information further includes: and a second indication. The second indication is used for indicating that the carrier scheduling mode is supported to be dynamically adjusted.

(3) And the terminal equipment defaults to support the same carrier scheduling mode.

The description is made with respect to item (1):

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

Optionally, the preset bit and the preset length may be configured by a network device, and the present application does not limit how to determine the preset bit and the preset length, and the position of the preset bit and the preset length.

Optionally, the preset length may be 1, correspondingly, a value of the first indication may be 0 or 1, and when the value of the first indication is 0, the first indication indicates that the same-carrier scheduling mode of the first serving cell of the terminal device is supported. Or, when the first indication value is 1, the same-carrier scheduling mode of the first serving cell supporting the terminal device is indicated.

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

The following description is made with respect to item (2):

optionally, the second indication is at a serving cell level or at a terminal device level. That is, the second indication may indicate that the first serving cell supports dynamically adjusting the carrier scheduling. The terminal device may also be instructed to support adjusting the carrier scheduling manner.

Alternatively, 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, and when the value of the second indication is 0, it indicates that the carrier scheduling manner is supported to be dynamically adjusted. Or, when the first indication value is 1, it indicates that the carrier scheduling manner is supported to be dynamically adjusted.

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, and based on this, the terminal device may dynamically adjust the carrier scheduling mode according to the indication information.

It should be understood that, when the initial default carrier scheduling manner of the first serving cell is the same-carrier scheduling manner, then activating the same-carrier scheduling manner may be understood as using the same-carrier scheduling manner; when the initial default carrier scheduling mode of the first serving cell is a cross-carrier scheduling mode, activating the same-carrier scheduling mode may be understood as switching the carrier scheduling mode to the cross-carrier scheduling mode or using the cross-carrier scheduling mode; when the initial default carrier scheduling manner of the first serving cell is the cross-carrier scheduling manner, activating the same-carrier scheduling manner may be understood as switching the carrier scheduling manner to the same-carrier scheduling manner or using the same-carrier scheduling manner; when the initial default carrier scheduling mode of the first serving cell is a cross-carrier scheduling mode, then activating the cross-carrier scheduling mode may be understood as using the cross-carrier scheduling mode.

Alternatively, "active" is relative to "inactive", and the initial default carrier scheduling manner may be understood as the carrier scheduling manner in the inactive state.

It should be noted that the time when the terminal device receives the indication information is the same as the time when the cross-carrier scheduling manner or the same-carrier scheduling manner is activated. Or the time difference between the time when the terminal equipment 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, a slot, or the like, which is not limited in this application.

To sum up, in the present application, the terminal device may determine whether to activate a cross-carrier scheduling manner or a same-carrier scheduling manner of a first serving cell of the terminal device according to the indication information to dynamically adjust the carrier scheduling manner, so as to improve adaptivity of the carrier scheduling manner to adapt to a cell environment, such as a change of interference, for example: when the interference of the first serving cell is large, the terminal device may activate a cross-carrier scheduling manner to perform data scheduling in other cells. When the interference of the first serving cell is small, the terminal device may activate the same-carrier scheduling manner to perform data scheduling in the cell.

The following will describe the above indication information in detail, wherein the function of the indication information is as follows, but not limited to:

(1) The indication information comprises a plurality of bits, and each bit is used for indicating whether a serving cell activates a cross-carrier scheduling mode or a same-carrier scheduling mode of the serving cell.

And Ci corresponds to the serving cell with the ID of i and configured with a cross-carrier scheduling mode, and the value of Ci indicates whether the same-carrier scheduling mode or the cross-carrier scheduling mode of the serving cell is activated. For example, 0 indicates activation of the same carrier scheduling, and 1 indicates activation of the cross-carrier scheduling. Alternatively, 1 indicates activation of the same-carrier scheduling, and 0 indicates activation of the cross-carrier scheduling. The indication information or the MAC CE includes a number of bits ceil (n/8) × 8, where n is the number of serving cells supporting the cross-carrier scheduling. ceil () is a ceiling function. For example, n =12, the mac CE includes the number of bits Ceil (12/8) × 8=16.

The following is explained with respect to item (3):
