Description

A method, device and system for determining BWP status

technical field

The embodiments of the present application relate to the field of communications technologies, and in particular, to a method, device, and system for determining a bandwidth part (Bandwidth Part, BWP) state.

Background technique

The fifth-generation (5th-Generation, 5G) mobile communication New Radio (NR) standardization work discusses the data transmission situation of terminal equipment whose bandwidth capability is smaller than the system bandwidth. For example, at the Radio Access Network (RAN) 1#88 conference, it was discussed to support the data transmission of terminal devices with bandwidth capabilities smaller than the system bandwidth through a two-step resource allocation method, that is, the terminal device first indicates a BWP, and then Resource allocation and data transmission are performed in this bandwidth portion. At the RAN1#88b conference, it was further clarified that for a carrier, the network can configure one or more bandwidth parts for terminal equipment in a semi-static manner, and the bandwidth of each bandwidth part is not greater than the maximum bandwidth capability of the terminal equipment. At the RAN1#89 conference, the way of activating/deactivating the bandwidth part to realize the handover between multiple bandwidth parts on the same carrier was discussed and supported.

Figure 1 is a typical bandwidth partial switching scenario, as shown in Figure 1. The terminal device is configured with two bandwidth parts: BWP1 and BWP2. The bandwidth of BWP1 is smaller, and the bandwidth of BWP2 is larger. When the traffic to be transmitted is small, the terminal device only monitors the PDCCH on BWP1, that is, the bandwidth of the small bandwidth at this time. The part is activated, and the part of the bandwidth with large bandwidth is deactivated; when the amount of data to be transmitted is large, the terminal device switches to BWP2 according to the cross-BWP scheduling (Cross-BWP Grant), and detects on the part of the large bandwidth. PDCCH, that is, at this time, the bandwidth part of the small bandwidth is deactivated, and the bandwidth part of the large bandwidth is activated. In this way, handover between BWPs in the same carrier is realized.

As can be seen from FIG. 1 , before the BWP is switched, the terminal device needs to know the activation/deactivation state of the BWP in order to switch to the activated BWP. However, at present, it is difficult for the terminal device to determine the status of the BWP. In particular, as a form of frequency resource deployment in NR, Carrier Aggregation (CA) is also introduced in NR, that is, multiple Component Carriers (CC) are introduced, and each cc may With multiple different BWPs configured, for multiple BWPs on so many carriers, how to determine the activation/deactivation status of BWPs on the carriers becomes an urgent issue to be discussed in NR.

Wherein, as an example, the access network device may be the access network device in FIG. 2 , and the terminal device may be the terminal device in FIG. 2 .

The first carrier may be any one of one or more carriers pre-configured by the access network device to the terminal device, may be a single carrier, or may be any component carrier (Component Carrier, CC) among multiple carriers, At least one BWP on the first carrier may include multiple activated BWPs and deactivated BWPs, where the activated BWP may refer to a BWP in a state, and the deactivated BWP may refer to a BWP in a deactivated state. The at least one BWP on the first carrier may include an activated BWP, and may also include a deactivated BWP, which is not limited.

Optionally, the access network device may configure at least one BWP on the first carrier and the activation/deactivation state of each BWP on the first carrier for the terminal device by using high-layer signaling configuration, which will not be repeated here.

Among them, the bandwidth part and BWP are equivalent concepts, and the bandwidth part can be a continuous or non-consecutive resource in the frequency domain, which is related to a specific system parameter. At least one; for example: a bandwidth part includes K consecutive or non-consecutive subcarriers; or, a bandwidth part is a frequency domain resource where K non-overlapping continuous or non-consecutive resource blocks (Resource Block, RB) are located; or , a bandwidth part is the frequency domain resources where K non-overlapping continuous or non-consecutive resource block groups (Resource Block Group, RBG) are located, and an RBG includes P consecutive RBs, where K is an integer greater than 0, P is an integer greater than 0, without limitation.

Step 402: The access network device sends indication information to the terminal device, where the indication information is used to indicate the activation/deactivation state of the bandwidth part on the first carrier.

The information on a carrier including multiple bits may also be information including the identification information of the carrier and the identification information of the bandwidth part on the carrier as shown in FIG. 5d , which is not limited. Specifically, for the design form of the indication information in this embodiment of the present application, reference may be made to the following related descriptions, which will not be repeated here.

Optionally, the access network device carries the indication information in the MAC CE or other signaling messages and sends it to the terminal device, and the terminal device receives the indication information from the MAC CE or other signaling messages carrying the indication information.

In the deactivated state, the PDCCH is monitored on the activated BWP. In this way, the problem of how to determine the activation/deactivation status of the BWP on the carrier is solved.

Wherein, the indication information in the solution shown in FIG. 4 may be in any of the following forms (1) to (4):

(1): the indication information includes a first bitmap, the first bitmap includes at least one bit, at least one bit corresponds to at least one BWP on the first carrier, and the value of each bit is used to indicate a bit The activation/deactivation status of the corresponding BWP.

Wherein, in this form, the indication information includes not only the first bitmap, but also multiple other bitmaps, that is, the indication information may include at least one bitmap, at least one bitmap is in one-to-one correspondence with at least one carrier, and each bitmap The included at least one bit is in one-to-one correspondence with at least one BWP on the carrier corresponding to the bitmap. The corresponding relationship between at least one bitmap and at least one carrier can be preconfigured by the network to the terminal device. For example, the access network device can configure the following correspondence to the terminal device: bitmap 1 corresponds to carrier 1, and bitmap 2 corresponds to carrier 2 , bitmap 3 corresponds to carrier 3, so that the terminal device can know which bitmap corresponds to which carrier.

The correspondence between the bits contained in each bitmap and the bandwidth part on the carrier corresponding to the bitmap can be pre-configured by the network to the terminal device, and each bit can carry a 1-bit value, for example, the number 1 can be used to indicate that the bandwidth part corresponding to the bit is in the active state, that is, the bandwidth part is the active BWP, and the number 0 is used to indicate that the bandwidth part corresponding to the bit is in the deactivated state, that is, the bandwidth part is the deactivated BWP, you can also use Other different characters on a bit represent the activation/deactivation state of the bandwidth part corresponding to the bit, which is not limited. For example, when a bitmap corresponds to carrier 1, and bit 1 in the bitmap corresponds to bandwidth part 1, bit 2 corresponds to bandwidth part 2, and the value carried by bit 1 is 1, the When the value is 0, it indicates that the bandwidth part 1 corresponding to the bit 1 is the activated BWP, and the bandwidth part 2 corresponding to the bit 2 is the deactivated BWP.

For example, as shown in Figure 5a, it includes N carriers, and each carrier has an active or inactive bandwidth part, the indication information sent by the access network device to the terminal device may include N bitmaps, N bits The map corresponds to the N carriers one by one, and the bits in each bitmap correspond to the bandwidth part on the carrier. For example, the first bit of the bitmap 1 corresponds to the BWP1 on the carrier 1, which can carry the activation of BWP1/ Deactivation information (if this bit is 1, it means BWP1 is activated, and this bit is 0 means BWP1 is deactivated), the second bit corresponds to BWP2 on carrier 1, and can carry BWP2 activation/deactivation information (such as this bit The bit is 1, which means BWP2 is activated, and the bit is 0, which means BWP2 is deactivated); the first bit of bitmap N corresponds to BWPx on carrier N, and can carry the activation/deactivation information of BWPx (such as this bit is 1, which means BWPx is activated, the bit 0 means BWPx deactivation), the second bit corresponds to BWPy on carrier N, and can carry the activation/deactivation information of BWPy (if the bit is 1, it means BWPy is activated , the bit 0 indicates BWPy deactivation). In this way, when the indication information received by the terminal device includes N bitmaps, the activation/deactivation state of the BWP can be determined according to the value of the bit corresponding to the BWP on the carrier in each bitmap.

It should be noted that, in addition to the bits used to indicate the activation/deactivation state of the bandwidth part, each bitmap may also include bits that carry other information, as shown in Figure 5a, and may also include blank padding ( padding), without restriction.

(2): The indication information includes a bitmap, the bitmap includes M bits, and the M bits are in one-to-one correspondence with the BWPs on the N carriers, the total number of BWPs on the N carriers is M, and M is greater than or equal to An integer of 1, N is an integer greater than or equal to 1, and the N carriers include the first carrier; the value of the bit corresponding to the BWP on the first carrier in the indication information is used to indicate the activation/deactivation of the BWP on the first carrier active state.

For example, it is assumed that the access network device configures two carriers for the terminal device: carrier 1 and carrier 2. Carrier 1 includes 3 BWPs, and carrier 2 includes 2 BWPs. In this implementation manner, the indication information may include 5 BWPs. Bitmap of bit bits, these 5 bits correspond to 3 BWPs on carrier 1 and 2 BWPs on carrier 2 one-to-one. In this way, the terminal device may indicate activation/deactivation of the bandwidth portion on the first carrier according to the bit corresponding to the bandwidth portion on the first carrier in the indication information.

The correspondence between the M bits and the BWP on the N carriers may be pre-configured by the network to the terminal device. Each bit can carry a 1-bit value. For example, the number 1 can be used to indicate that the bandwidth part corresponding to the bit is in the active state, and the number 0 can be used to indicate that the bandwidth part corresponding to the bit is in the deactivated state. The activation/deactivation state of the bandwidth part corresponding to the bit is represented by other different characters on the bit, which is not limited. For example, when bit 1 corresponds to the bandwidth part 1 of carrier 1, bit 2 corresponds to the bandwidth part 1 of carrier 2, and the value carried by bit 1 is 1, and the value on bit 2 is 0, it indicates that the carrier Bandwidth part 1 of 1 is BWP activated, and bandwidth part 2 of carrier 2 is BWP deactivated.

For example, as shown in Fig. 5b, there are N carriers, each carrier has at least one active or inactive bandwidth part, and the total number of BWPs on the N carriers is M, then the access network device sends a message to the terminal device. The indication information can contain 1 bitmap, the bitmap can contain M bits, the M bits correspond to M bandwidth parts, and the M bandwidth parts can be composed of all BWPs on N carriers, such as : Bit 1 corresponds to BWP1 of carrier 1. When the bit is 1, it means that the BWP1 of carrier 1 is in the active state, which is the activated BWP, and the bit is 0, which means that the BWP1 of the carrier 1 is in the deactivated state, which is the deactivated BWP; The two bits correspond to the BWP2 of the carrier 1. When the bit is 1, it means that the BWP2 of the carrier 1 is in the active state, which is to activate the BWP. When the bit is 0, it means that the BWP2 of the carrier 1 is in the deactivated state, which is to deactivate the BWP, etc. ; The third bit corresponds to the BWP1 of carrier 2. When the bit is 1, it indicates that the BWP1 of carrier 2 is in the active state, which is to activate BWP, and the bit is 0 to indicate that the BWP1 of carrier 2 is in the deactivated state, which is to deactivate the BWP ;...; The last bit (the Mth bit) corresponds to the BWP of the last number of the carrier N (BWPy in the figure), when the bit is 1, it means that the BWP of the last number of the carrier N is the active BWP. A value of 0 indicates that the last numbered BWP of carrier N is a deactivated BWP.

It is understandable that, in addition to the bits used to indicate the activation/deactivation bandwidth part, the above bitmap may also include bits carrying other information, as shown in FIG. 5b , and may also include padding, which is not limited.

(3): The indication information is carried in the MAC CE of the downlink physical channel on the first carrier, and the indication information carried by the indication information includes at least one bit, and at least one bit corresponds to at least one BWP on the first carrier. Each The value of the bit is used to indicate the activation/deactivation state of the BWP corresponding to the bit.

Wherein, the corresponding relationship between the at least one bit and at least one bandwidth part on the first carrier can be pre-configured by the network to the terminal device, and each bit can carry a value of 1 bit, for example: the number 1 can be used to indicate the The bandwidth part corresponding to the bit is in the active state, and the number 0 is used to indicate that the bandwidth part corresponding to the bit is in the deactivated state, and other different characters on the bit can be used to indicate the activation/deactivation of the corresponding bandwidth part of the bit status, without restrictions. For example, when bit 1 corresponds to bandwidth part 1, bit 2 corresponds to bandwidth part 2, and the value carried by bit 1 is 1, and the value on bit 2 is 0, determine the bandwidth part 1 corresponding to bit 1 In the active state, the bandwidth part 2 corresponding to the bit 2 is in the inactive state.

Optionally, the access network device sending the indication information to the terminal device includes: the access network device sends a downlink physical channel to the terminal device on the first carrier, and the indication information is carried in the MAC CE of the downlink physical channel.

Before the access network device sends the indication information through the first carrier, the method may further include:

The access network device sends the DCI to the terminal device on the second carrier; wherein the DCI includes a CIF, the CIF is used to indicate the first carrier, and the DCI is used to indicate scheduling of a downlink physical channel on the first carrier.

Before performing the above process, if the first carrier is not in an activated state, a process of activating the first carrier needs to be performed, for example, the activation of the first carrier may be indicated by information carried by other activated carriers. The specific implementation is as follows:

When the first carrier is not activated, the access network device sends information indicating activation of the first carrier to the terminal device on the second carrier, so that the terminal device activates the first carrier according to the information, where the information can be carried in the first carrier In the MAC CE on the two carriers.

Without loss of generality, the present invention does not exclude the use of other first carrier activation methods.

For example, assuming that the first carrier is the target carrier, as shown in Figure 5c, the target carrier is in an active state, and the target carrier includes two bandwidth parts, BWPx and BWPy, when the access network device configures the activation of the bandwidth part on the target carrier / After the deactivation state, the access network device sends the DCI containing the CIF on the primary carrier in the active state, the CIF is used to instruct the downlink physical channel to be scheduled on the target carrier, and the access network device is on the downlink physical channel of the target carrier. Send indication information, the indication information contains two bits corresponding to the bandwidth part of the target carrier, the first bit corresponds to BWPx and can carry the activation/deactivation information of BWPx, the second bit corresponds to BWPy, can Carry the activation/deactivation information of BWPy.

It should be noted that, in addition to the bits used to indicate the activation/deactivation bandwidth part, the above indication information may also include bits carrying other information, as shown in FIG. 5c , and may also include padding, which is not limited.

(4): The indication information includes the identification information of the first carrier and the identification information of the BWP on the first carrier; the identification information of the first carrier is used to identify the first carrier, and the identification information of the BWP is used to identify the first carrier. Activate BWP.

The identification information of the first carrier is used to identify the first carrier, and may be the identification information of the first carrier, such as the number of the first carrier, and the number may be a number or other letters or symbols, which is not limited. For example, if the number of 1 of the first carrier is 1, the identification information of the first carrier is 1.

The identification information of the bandwidth part is used to identify the bandwidth part, and may be identification information of the bandwidth part, such as the number of the bandwidth part, and the number may be a number or other letters or symbols, which is not limited. For example, if the number of 1 in the bandwidth part is 1, the identification information of the bandwidth part is 1.

Wherein, in this design form of the indication information, the indication information can be carried on the first carrier in the active state and sent to the terminal device, or can be carried on other carriers in the active state other than the first carrier and sent to the terminal device, No restrictions.

For example, as shown in Figure 5d, the indication information includes the identification information of carrier N and the identification information of the bandwidth part on carrier N to indicate the bandwidth part on the activated carrier N, for example: the indication information in the indication information includes carrier 1 and the number A of the bandwidth part 1 on the carrier 1, it indicates to activate the bandwidth part 1 on the carrier 1, so that when the terminal device receives the indication information, it is determined that the bandwidth part 1 on the carrier 1 is in the active state , and the remaining bandwidth part on carrier 1 may be in a deactivated state, which is BWP deactivated.

It should be noted that, in addition to the identification information of carrier N and the identification information of the bandwidth part on carrier N, the indication information may also include bits carrying other information, such as padding, which is not limited.
