Description

Technical Field

[0001] This invention relates to wireless access technology, and more particularly to a frequency hopping configuration method for Bandwidth Part (BWP) and network devices and terminals. Background Technology

[0002] In New Radio (NR) systems such as 5G applications, frequency hopping can be used in physical channels to achieve frequency selectivity gain and improve transmission performance. With the introduction of the concept of Bandwidth Part (BWP), since a terminal can be configured with multiple BWPs, frequency hopping in each BWP can be achieved by uniformly configuring the frequency domain shift of the physical channel according to the BWP with the smallest bandwidth.

[0003] However, because the frequency shift of the physical channel is uniformly configured according to the minimum bandwidth BWP, it is impossible to fully utilize the larger bandwidth of the larger bandwidth BWP to achieve a larger frequency hopping amplitude, thus limiting the frequency selective gain and resulting in a reduction in the transmission performance of the physical channel. Summary of the Invention

The first configuration information is used to indicate at least one frequency domain shift configured for each BWP in at least one BWP.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0029] The main idea of ​​this invention is to configure different frequency domain shift sets for different BWPs, make full use of the bandwidth of each BWP, and maximize the frequency hopping shift without exceeding the bandwidth of the BWP to obtain a greater frequency selectivity gain, thereby improving the transmission performance of the physical channel.

[0030] Figure 1A This is a flowchart illustrating a frequency hopping configuration method for a BWP according to an embodiment of the present invention, as shown below. Figure 1A As shown.

[0031] 101. The network device sends first configuration information of the transmission physical channel to the terminal, the first configuration information being used to indicate at least one frequency domain shift configured for each of at least one BWP.

[0032] Frequency offset refers to the frequency offset between two hops in a frequency hopping process, which can be represented by the number of resource blocks (RBs).

[0033] Optionally, in one possible implementation of this embodiment, the physical channel may include, but is not limited to, at least one of the Physical Uplink Shared Channel (PUSCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Control Channel (PUCCH), and Physical Downlink Control Channel (PDCCH).

[0034] Optionally, in one possible implementation of this embodiment, in step 101, the network device may send the first configuration information of the transmission physical channel to the terminal via higher-layer signaling or system broadcast messages.

[0035] For example, the higher-layer signaling can be Radio Resource Control (RRC) signaling. Specifically, the first configuration information can be carried through the Information Element (IE) in the RRC signaling. The RRC signaling can be existing RRC signaling, such as the RRC Connection Reconfiguration message. This embodiment does not limit this. The first configuration information can be carried by extending the IE of existing RRC signaling, or the RRC signaling can be different from existing RRC signaling.

[0036] For example, the first configuration information can be carried using spare bits in the existing Master Information Block (MIB) or System Information Block (SIB) in the system broadcast message, or a new SIB can be added to carry the first configuration information.

[0037] In this invention, the network device can further send second configuration information to the terminal to instruct on configuring the at least one BWP. After receiving the second configuration information, the terminal can determine the position of each BWP among the at least one BWP.

[0038] Specifically, network devices can send second configuration information to terminals through higher-level signaling or system broadcast messages.

[0039] For example, the higher-layer signaling can be Radio Resource Control (RRC) signaling. Specifically, the second configuration information can be carried through the Information Element (IE) in the RRC signaling. The RRC signaling can be existing RRC signaling, such as the RRC Connection Reconfiguration message. This embodiment does not limit this. The second configuration information can be carried by extending the IE of existing RRC signaling. Alternatively, the RRC signaling can be different from existing RRC signaling.

[0040] For example, the second configuration information can be carried using spare bits in the existing Master Information Block (MIB) or System Information Block (SIB) in the system broadcast message, or a new SIB can be added to carry the second configuration information.

[0041] Optionally, in one possible implementation of this embodiment, after step 101, the network device may further send first control information to the terminal. This first control information is used to indicate an active BWP among the at least one BWP. Thus, after receiving the first control information, the terminal can determine at least one frequency domain shift of the active BWP.

[0042] Specifically, network devices can send the first control information to the terminal through downlink control information (DCI) or higher-layer signaling.

[0043] For example, the higher-layer signaling can be a Media Access Control (MAC) Control Element (CE) message, or more specifically, it can be achieved by adding a new MAC CE message to carry the first control information.

[0044] Optionally, in one possible implementation of this embodiment, after step 101, the network device may further send second control information to the terminal. This second control information indicates a used frequency domain shift within the at least one frequency domain shift. Thus, after receiving the second control information, the terminal can determine a used frequency domain shift for the activated BWP.

[0045] Specifically, network devices can send second control information to the terminal through downlink control information (DCI) or higher-layer signaling.

[0046] For example, the higher-layer signaling can be a Media Access Control (MAC) Control Element (CE) message, or more specifically, a new MAC CE message can be added to carry the second control information.

[0047] Optionally, in one possible implementation of this embodiment, after step 101, the network device may further send third control information to the terminal, the third control information being used to indicate the position of the first frequency domain resource for transmitting the physical channel in the activated BWP.

[0048] Specifically, network devices can send third control information to terminals through downlink control information (DCI) or higher-layer signaling.

[0049] For example, the higher-layer signaling can be a Media Access Control (MAC) Control Element (CE) message, or more specifically, it can be achieved by adding a new MAC CE message to carry the third control information.

[0050] Optionally, in one possible implementation of this embodiment, after step 101, the network device may further transmit the physical channel with the terminal on the first frequency domain resource and the second frequency domain resource for transmitting the physical channel, wherein the position of the second frequency domain resource in the activated BWP is determined by the formula R2 = (R1 + W). offset The value is determined by mod W. Where R2 is the position of the second frequency domain resource in the active BWP; R1 is the position of the first frequency domain resource in the active BWP; W offset is the frequency domain shift used; W is the bandwidth of the active BWP.

[0051] It should be noted that the network device can also send at least one of the first control information, the second control information, and the third control information to the terminal without using higher-layer signaling or system broadcast messages. In this way, the terminal can obtain the content indicated by at least one of the first control information, the second control information, and the third control information according to pre-configuration, such as protocol agreements. 9

[0052] To make the method provided in the embodiments of the present invention clearer, the following will take configuring one frequency domain shift and configuring two different frequency domain shift sets for different BWPs as examples respectively.

[0053] Figure 1B for Figure 1A A schematic diagram of a frequency domain shift configuration provided in the corresponding embodiment. For example... Figure 1B As shown, assume that two BWPs, BWP1 and BWP2, are configured for the terminal. The bandwidth of BWP1 is W1, and the bandwidth of BWP2 is W2. A frequency domain shift W is configured for BWP1. offset1 A frequency domain shift W was configured for BWP2. offset2 .

[0054] If BWP1 is activated, the terminal will proceed according to W. offset1 Given the location of the first frequency domain resource, i.e., the frequency domain location of the first hop, R1, determine the location of the second frequency domain resource, i.e., the frequency domain location of the second hop, R2 = (R1 + W). offset1 )mod W1.

[0055] If BWP2 is activated, the terminal will proceed according to W... offset2 Given the frequency domain position R1 of the first hop, determine the frequency domain position R2 of the second hop: R2 = (R1 + W) offset2 )mod W2.

[0056] Figure 1C for Figure 1A A schematic diagram of another frequency domain shift configuration provided in the corresponding embodiment. For example... Figure 1C As shown, assume that two BWPs, BWP1 and BWP2, are configured for the terminal. The bandwidth of BWP1 is W1, and the bandwidth of BWP2 is W2. Two frequency domain shifts, W1, W2, and W2, are configured for BWP1. offset1_1 and W offset1_2 Two frequency domain shifts, namely W, are configured for BWP2. offset2_1 and W offset2_2 .

[0057] If BWP1 is activated, and the base station instructs the terminal to use the first frequency domain shift W offset1_1 Then the terminal according to W offset1_1 Given the frequency domain position R1 of the first hop, determine the frequency domain position R2 of the second hop: R2 = (R1 + W) offset1_1)mod W1.

[0058] If BWP1 is activated, and the base station instructs the terminal to use the second frequency domain shift W offset1_2 Then the terminal according to W offset1_2 Given the frequency domain position R1 of the first hop, determine the frequency domain position R2 of the second hop: R2 = (R1 + W) offset1_2 )mod W1.

[0059] If BWP2 is activated, and the base station instructs the terminal to use the first frequency domain shift W offset2_1 Then the terminal according to W offset2_1 Given the frequency domain position R1 of the first hop, determine the frequency domain position R2 of the second hop: R2 = (R1 + W) offset2_1 )mod W1.

[0060] If BWP2 is activated, and the base station instructs the terminal to use the second frequency domain shift W offset2_2 Then the terminal according to W offset2_2 Given the frequency domain position R1 of the first hop, determine the frequency domain position R2 of the second hop: R2 = (R1 + W) offset2_2 )mod W1.

[0061] In this embodiment, the network device sends first configuration information of the transmission physical channel to the terminal. The first configuration information is used to indicate at least one frequency domain shift configured for each BWP in at least one BWP. This realizes the configuration of different frequency domain shift sets for different BWPs, making full use of the bandwidth of each BWP. This allows the frequency hopping shift to be maximized without exceeding the bandwidth of the BWP, so as to obtain a greater frequency selectivity gain and thus improve the transmission performance of the physical channel.

[0067] Optionally, in one possible implementation of this embodiment, in step 201, the terminal may specifically receive the first configuration information sent by the network device through higher-layer signaling or system broadcast messages.

[0068] For example, the higher-layer signaling can be Radio Resource Control (RRC) signaling. Specifically, the first configuration information can be carried through the Information Element (IE) in the RRC signaling. The RRC signaling can be existing RRC signaling, such as the RRC Connection Reconfiguration message. This embodiment does not limit this. The first configuration information can be carried by extending the IE of existing RRC signaling, or the RRC signaling can be different from existing RRC signaling.

[0069] For example, the first configuration information can be carried using spare bits in the existing Master Information Block (MIB) or System Information Block (SIB) in the system broadcast message, or a new SIB can be added to carry the first configuration information.

[0070] In this invention, the terminal can further receive second configuration information sent by the network device to instruct the configuration of the at least one BWP, thereby determining the position of each BWP among the at least one BWP.

[0071] Specifically, the terminal can receive the second configuration information sent by the network device through higher-layer signaling or system broadcast messages.

[0072] For example, the higher-layer signaling can be Radio Resource Control (RRC) signaling. Specifically, the second configuration information can be carried through the Information Element (IE) in the RRC signaling. The RRC signaling can be existing RRC signaling, such as the RRC Connection Reconfiguration message. This embodiment does not limit this. The second configuration information can be carried by extending the IE of existing RRC signaling. Alternatively, the RRC signaling can be different from existing RRC signaling.

[0073] For example, the second configuration information can be carried using spare bits in the existing Master Information Block (MIB) or System Information Block (SIB) in the system broadcast message, or a new SIB can be added to carry the second configuration information.

[0074] Optionally, in one possible implementation of this embodiment, such as Figure 2B As shown, after step 201, step 203 can be further executed, in which the terminal receives first control information sent by the network device. This first control information is used to indicate an active BWP among the at least one BWP. In this way, the terminal can determine at least one frequency domain shift of the active BWP.

[0075] Specifically, the terminal may receive the first control information sent by the network device through downlink control information (DCI) or higher-layer signaling.

[0076] For example, the higher-layer signaling can be a Media Access Control (MAC) Control Element (CE) message, or more specifically, it can be achieved by adding a new MAC CE message to carry the first control information.

[0077] Optionally, in one possible implementation of this embodiment, such as Figure 2B As shown, after step 201, step 204 can be further executed, whereby the terminal receives second control information sent by the network device. This second control information indicates a used frequency domain shift within the at least one frequency domain shift. In this way, the terminal can determine a used frequency domain shift for the activated BWP.

[0079] For example, the higher-layer signaling can be a Media Access Control (MAC) Control Element (CE) message, or more specifically, a new MAC CE message can be added to carry the second control information.

[0080] Optionally, in one possible implementation of this embodiment, after step 201, the terminal may further receive third control information sent by the network device. This third control information indicates the position of the first frequency domain resource for transmitting the physical channel within the activated BWP. In this way, the terminal can determine the position of the first frequency domain resource for transmitting the physical channel within the activated BWP.
