In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life business, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization began developing 5G. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, emmbb), low latency high reliability communication (URLLC), large-scale Machine-based communication (mctc).

On the one hand, embbs still target users to obtain multimedia content, services and data, and their demand is growing very rapidly. On the other hand, since an eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., its capabilities and requirements are also quite different, so that detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the mobile operators from early investment in LTE, a working mode of close cooperation (tight interworking) between LTE and NR is proposed.

To enable 5G network deployment and commercial applications as soon as possible, 3GPP first completes the first 5G release, EN-DC (LTE-NR Dual Connectivity). In EN-DC, an LTE base station (eNB) serves as a Master Node (MN), and an NR base station (gNB or EN-gNB) serves as a Secondary Node (SN), which is connected to an EPC core network. In the later stages of R15, other DC modes, namely NE-DC,5GC-EN-DC, NR DC will be supported. In NE-DC, NR base station is used as MN, eLTE base station is used as SN, and is connected with 5GC core network. In 5GC-EN-DC, an eLTE base station is used as MN, an NR base station is used as SN, and a 5GC core network is connected. In NR DC, NR base station is used as MN, NR base station is used as SN, and connected with 5GC core network.

In 5G, the maximum channel bandwidth may be 400MHZ (known as wideband carrier), which is a large bandwidth compared to the LTE maximum 20M bandwidth. To meet the high rate requirements, carrier aggregation (Carrier Aggregation, CA) techniques are supported in 5G. The CA enables the NR system to support a larger bandwidth by jointly scheduling and using resources on a plurality of component carriers (Component Carrier, CC), thereby enabling a higher system peak rate. Spectrum continuity according to the aggregated carriers can be divided into continuous carrier aggregation and discontinuous carrier aggregation; according to whether the frequency bands (bands) where the aggregated carriers are located are the same, the method is divided into Intra-band (Intra-band) carrier aggregation and inter-band (inter-band) carrier aggregation.

In CA there is and only one primary carrier (Primary Cell Component, PCC) providing RRC signaling connections, non-Access stratum (NAS) functionality, security, etc. The physical uplink control channel (Physical Downlink Control Channel, PUCCH) is present on and only on the PCC. In CA there may be one or more secondary carriers (Secondary Cell Component, SCC), which provide only additional radio resources. The PCC and the SCC are commonly referred to as Serving cells (Serving cells), where the cells on the PCC are primary cells (PCell) and the cells on the SCC are secondary cells (SCell).

Fig. 2 and 3 are protocol stack diagrams in a carrier aggregation scenario, where fig. 2 is a protocol stack diagram for downlink, and fig. 3 is a protocol stack diagram for uplink, and it can be seen that one CC corresponds to one HARQ entity.

In carrier aggregation, since the conventional traffic is downlink traffic, the number of downlink carriers is greater than the number of uplink carriers. In addition, when configuring carriers, the associated downlink carrier and uplink carrier are configured at the same time.

In the evolution process of 5G and later period, various novel services can appear, the uplink traffic volume can be larger and larger, and the uplink throughput can be improved by increasing the number of uplink carriers. Due to the large number of uplink carriers, there may be a case where the uplink carriers do not have corresponding downlink carriers, which may cause the downlink scheduling of the uplink carriers to be unresolved. In addition, in the conventional carrier configuration manner, one uplink carrier is fixedly configured to be associated with one downlink carrier, so that the flexibility of data scheduling is limited.

For this reason, the following technical solutions of the embodiments of the present application are provided.

In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application.

Application example 1

The network device configures at least one SCell through RRC signaling, and the SCell may include only one downlink carrier, or one uplink carrier and one downlink carrier, or only one uplink carrier.

In some alternative embodiments, each SCell of the at least one SCell is configured with one SCell index.

In some alternative embodiments, for scells comprising only one downlink carrier, or one uplink carrier and one downlink carrier, the SCell is identified by PCI and downlink frequency point. The PCI and downlink frequency point of the SCell are used for SCell search including only uplink carriers to identify the SCell.

In some alternative embodiments, for an SCell including only one uplink carrier, the SCell is configured to associate identification information of one target SCell, which may be an SCell index of the target SCell, or a PCI and a downlink frequency point. Here, the target SCell includes one downlink carrier, optionally one uplink carrier, and through the identification information of the target SCell, the downlink carrier associated with the Only UL carrier (i.e., only one uplink carrier included in the SCell) may be indicated.

In some optional embodiments, the association relationship between the downlink carrier and the uplink carrier configured semi-statically by RRC signaling may be dynamically changed by MAC CE or DCI. It should be noted that, for one SCell in RRC signaling, a downlink carrier and an uplink carrier are configured at the same time, and the association relationship between the downlink carrier and the uplink carrier cannot be dynamically changed by MAC CE or DCI.

In the embodiment of the application, the formats of the MAC CEs are numerous. As an example, referring to fig. 5, the SCell index of the target SCell is included in the MAC CE, the target SCell includes one downlink carrier (hereinafter referred to as a target downlink carrier), the MAC CE further includes a bitmap (bitmap), each bit (Ci) in the bitmap corresponds to the SCell index of one SCell (the SCell refers to the SCell including only one uplink carrier), a value of 1 (or 0) indicates that the uplink carrier in the corresponding SCell has an association relationship with the target downlink carrier, and a value of 0 (or 1) indicates that the uplink carrier in the corresponding SCell does not have an association relationship with the target downlink carrier. The set of uplink carriers associated with the target downlink carrier may be indicated by the MAC CE. It should be noted that, the MAC CE can only dynamically change the uplink carrier set associated with one target downlink carrier.

In some alternative embodiments, the length of the bitmap in the MAC CE is a variable length, e.g., the length of the bitmap depends on the number of uplink carriers (i.e., only UL carriers), and the number of bytes of the bitmap is equal to (the number of uplink carriers/8) and then rounded up.

In some alternative embodiments, the bits in the bitmap in the MAC CE are in order from low to high, and the SCell indexes corresponding to the uplink carriers in the uplink carrier set are in order from low to high, or the bits in the bitmap in the MAC CE are in order from low to high, and the SCell indexes corresponding to the uplink carriers in the uplink carrier set are in order from high to low.

In some alternative embodiments, the MAC CE corresponds to a new Logical Channel Identification (LCID) by which to identify and identify the MAC CE.

The format of the MAC CE is not limited to the format shown in fig. 5, and many other formats are possible. As an example, the MAC CE includes a plurality of SCell indexes, a first SCell index is an SCell index corresponding to a target downlink carrier, and other SCell indexes are SCell indexes corresponding to uplink carriers associated with the target downlink carrier. As an example, the MAC CE includes one SCell index and at least one carrier index, where the SCell index is an SCell index corresponding to the target downlink carrier, and the carrier index is a carrier index of an uplink carrier associated with the target downlink carrier.

Application instance two

The network device configures at least one SCell and at least one uplink carrier through RRC signaling, and the SCell may include only one downlink carrier or one uplink carrier and one downlink carrier. The uplink carrier refers to an Only UL carrier, which does not belong to one SCell.

In some alternative embodiments, for scells comprising only one downlink carrier, or one uplink carrier and one downlink carrier, the SCell is identified by PCI and downlink frequency point. The PCI and downlink frequency point of the SCell are used for Only UL carrier search to identify the SCell.

In some alternative embodiments, each of the at least one uplink carrier is configured with a carrier index.

In some alternative embodiments, for an uplink carrier (i.e., only UL carrier) configured to associate identification information of one target SCell, the identification information of the target SCell may be an SCell index of the target SCell, or a PCI and a downlink frequency point. Here, the target SCell includes a downlink carrier, optionally an uplink carrier, and the downlink carrier associated with the Only UL carrier may be indicated by the identification information of the target SCell.

In the embodiment of the application, the formats of the MAC CEs are numerous. As an example, referring to fig. 6, the MAC CE includes an SCell index of a target SCell, the target SCell includes a downlink carrier (hereinafter referred to as a target downlink carrier), the MAC CE further includes a bitmap (bitmap), each bit (UCi) in the bitmap corresponds to a carrier index of an uplink carrier (i.e., an Only UL carrier), a value of 1 (or 0) indicates that the corresponding uplink carrier has an association relationship with the target downlink carrier, and a value of 0 (or 1) indicates that the corresponding uplink carrier does not have an association relationship with the target downlink carrier. The set of uplink carriers associated with the target downlink carrier may be indicated by the MAC CE. It should be noted that, the MAC CE can only dynamically change the uplink carrier set associated with one target downlink carrier.

In some alternative embodiments, bits in the bitmap in the MAC CE are in one-to-one correspondence with carrier indexes of uplink carriers in the uplink carrier set in order from low to high, or bits in the bitmap in the MAC CE are in one-to-one correspondence with carrier indexes of uplink carriers in the uplink carrier set in order from high to low.

The format of the MAC CE is not limited to the format shown in fig. 6, and many other formats are possible. As an example, the MAC CE includes one SCell index and at least one carrier index, where the SCell index is an SCell index corresponding to the target downlink carrier, and the carrier index is a carrier index of an uplink carrier associated with the target downlink carrier.

In some optional embodiments, the association relationship between the downlink carrier and the uplink carrier configured semi-statically by RRC signaling may be dynamically changed by MAC CE or DCI.

In the embodiment of the application, the formats of the MAC CEs are numerous. As an example, referring to fig. 7, the MAC CE includes a carrier index of the target downlink carrier, and the MAC CE further includes a bitmap (bitmap), where each bit (UCi) in the bitmap corresponds to the carrier index of one uplink carrier, a value of 1 (or 0) of the bit indicates that the corresponding uplink carrier has an association relationship with the target downlink carrier, and a value of 0 (or 1) of the bit indicates that the corresponding uplink carrier does not have an association relationship with the target downlink carrier. The set of uplink carriers associated with the target downlink carrier may be indicated by the MAC CE. It should be noted that, the MAC CE can only dynamically change the uplink carrier set associated with one target downlink carrier.

In some alternative embodiments, the length of the bitmap in the MAC CE is a variable length, e.g. the length of the bitmap depends on the number of uplink carriers, and the number of bytes of the bitmap is equal to (number of uplink carriers/8) and then rounded up.

The format of the MAC CE is not limited to the format shown in fig. 7, and many other formats are possible. As an example, the MAC CE includes a carrier index of one downlink carrier and a carrier index of at least one uplink carrier, where the at least one uplink carrier has an association relationship with the downlink carrier.

Application example four

The network device configures a carrier group for the terminal device through the RRC signaling, wherein the carrier group comprises at least one uplink carrier and at least one downlink carrier. The change of the association relationship between the downlink carrier and the uplink carrier can only be performed in the carrier group.

It should be noted that, the solution of the application example four may be arbitrarily combined with the solutions of the application example one, the application example two, and the application example three.

Further, the number of bytes of the bitmap is equal to (number of uplink carriers in carrier group/8) and then rounded up.

In some alternative embodiments, the terminal device may send, through the RRC signaling network device, indication information, where the indication information is used to indicate a suggested carrier group and/or an association relationship between a suggested uplink carrier and a downlink carrier of the terminal device.
