Description

Configuration method of bandwidth part BWP and related equipment

Technical Field

The present disclosure relates to the field of communication technologies, and in particular, to a method for configuring a bandwidth portion BWP, a network device, a first capability terminal, a computer readable storage medium, and a computer program product.

Background

In the 3GPP (3 rd Generation Partnership Project, third generation partnership project) Rel-17 stage, research is being conducted on low-capability terminals (Reduced Capability NR (New Radio, new air interface/New Radio) Devices, abbreviated as RedCap), which have lower requirements for transmission rate and delay and lower terminal bandwidth capabilities than conventional terminals (hereinafter referred to as second-capability terminals).

Wherein, the RedCAP terminal can support the largest bandwidth, the FR1 can support 20MHz, and the FR2 can support 100MHz. For a normal terminal, FR1 can support 100MHz at maximum and FR2 can support 400MHz at maximum.

Since the bandwidth capabilities of the RedCap terminal and the normal terminal are different, in a scenario where the two terminals coexist, a situation may occur in which the operating bandwidth of the normal terminal is greater than the capability of the RedCap terminal. If the RedCap terminal continues to multiplex BWP (Bandwidth Part) of the normal terminal, access and service performance of the RedCap terminal may be seriously affected, and communication service quality of the deployed normal terminal may also be affected.

The following describes the relevant content of radio frequency retuning (RF retuning):

radio frequency retuning refers to frequency adjustment. When an RF radio frequency link moves from one frequency point to another frequency point, a certain time interval may be required for the RF device to work on the new frequency point due to parameter adjustment, which inevitably brings about a certain processing delay. In NR systems, the in-band RF return delay is approximately 50-200 us, depending on the sensitivity of the RedCAP terminal to delay.

The embodiment of the disclosure provides a method for configuring a BWP of a RedCAP terminal, which aims to solve the problem that the bandwidth capability of the RedCAP terminal and the bandwidth capability of a common terminal are not matched in a coexistence scene, improve the access and service performance of the RedCAP terminal, reduce the influence on the service quality of the deployed common terminal, and further improve the network performance and user experience.

Embodiments of the present disclosure propose a method for configuring a RedCap terminal BWP, which optionally supports newly adding a RedCap-specific IE element (referred to as a first capability terminal-specific information element, IE is a Information Element shorthand, i.e., an information element) via a proprietary signaling or SIB (System Information Block ) message, and separately configures the BWP for the RedCap terminal, which may be one or more of an Initial UL BWP (Initial uplink BWP), an Initial DL BWP (Initial downlink BWP), a Non-Initial UL BWP (Non-Initial downlink BWP), a Non-Initial DL BWP (Non-Initial downlink BWP), and the like, to solve the problem that bandwidth capabilities of the RedCap terminal and a general terminal are not matched in a coexistence scenario.

Furthermore, the bandwidth configuration of the RedCap terminals optionally supports an indication of the update by a third signaling to adapt the actual capabilities of the different RedCap terminals, maximizing the utilization of resources. The third signaling may be higher layer signaling or MAC (Media Access Control Address ) CE (control element) or DCI (Downlink Control Information, downlink control information).

As shown in fig. 2, a method provided by an embodiment of the present disclosure may include:

step S210: the second signaling is read to determine whether the BWP configuration of the RedCap-specific is supported, i.e., whether the BWP configuration for the RedCap terminal alone is supported.

In the embodiment of the present disclosure, the second signaling may be higher layer signaling.

In the embodiment of the disclosure, the second signaling may be newly added signaling or multiplexing existing signaling to indicate whether to support the BWP configuration of the RedCap-specific.

In the embodiment of the present disclosure, if the second signaling is to multiplex the existing signaling, a parameter may be added to the existing signaling to explicitly or implicitly indicate whether to support the BWP configuration of the RedCap-specific, or may be shared with the existing parameter to indicate whether to support the BWP configuration of the RedCap-specific. If the second signaling is a newly added signaling, whether to support the BWP configuration of the RedCap-specific may also be indicated explicitly or implicitly by the newly added instruction, which is not limited in the disclosure.

Step S230: if the BWP configuration of the RedCap-specific is not supported, the RedCap terminal multiplexes the BWP configuration of the normal terminal, which may be referred to as a second-capability terminal BWP in the embodiment of the present disclosure.

Step S240: optionally supporting the indication of updated bandwidth resources by third signaling (e.g. higher layer signaling or MAC CE or DCI) to adapt the terminal bandwidth capabilities.

In the embodiment of the present disclosure, the third signaling may be a newly added signaling, or may multiplex an existing signaling. For example, assuming that the BWP of the general terminal is 100MHz, one signaling (third signaling) is newly added or the existing signaling is multiplexed to configure the bandwidth of 20M for the RedCap terminal.

Step S220: if the BWP configuration of the RedCap-specific is supported, the BWP is configured for the RedCap terminal alone through the first signaling, and the RedCap-specific IE element may be newly added through dedicated signaling (dedicated signaling) or SIB message. The configured RedCap BWP (first capability terminal BWP) may be one or more of an Initial UL BWP, an Initial DL BWP, a Non-Initial UL BWP, and a Non-Initial UL BWP.

Step S240: further, updating bandwidth resources is optionally supported by higher layer signaling or MAC CE or DCI indication to adapt the terminal bandwidth capabilities.

For example, an Initial DL BWP is used to add a new RedCap-specific IE element, for example, an Initial downlink BWP-RedCap (Initial downlink BWP-RedCap), which is not limited to the RedCap field, and is characterized as a RedCap-specific field.

As to a specific embodiment of the configuration of the RedCap terminal BWP, the following is exemplified:

example 1: center frequency point relationship of RedCAP BWP-pair

In the TDD scenario, the center frequency points of the BWP pair (including DL BWP and UL BWP) of the RedCap terminal may be the same (as shown in fig. 3) or may be different (as shown in fig. 4), so as to increase flexibility of bandwidth configuration.

The embodiment of the disclosure allows the center frequency points of BWP pairs to be different, and can be placed at different positions of the bandwidth, so that the flexibility is improved.

When the center frequency points of a pair of BWP are different, the center frequency point of DL BWP can be adjusted to a proper frequency point position by means of radio frequency retuning (RF retuning), for example, as shown in fig. 4, the center frequency point of DL BWP is retuned to the same center frequency point as UL BWP.

The RF readjustment process brings a certain processing time delay, and is suitable for the RedCAP with insensitive time delay.

Example 2: relationship between Initial DL BWP and CORESET #0 (control resource set 0)

The Initial DL BWP of the RedCap terminal may contain all (as shown in fig. 5), part (as shown in fig. 6), or none (as shown in fig. 7) of CORESET #0.

As shown in fig. 6 and 7, when the Initial DL BWP of the RedCap terminal includes part or no coreset#0, the Initial DL BWP of the RedCap terminal may include all coreset#0 for the subsequent UE blind detection by RF return.

When the Initial DL BWP portion includes or does not include coreset#0, the Initial DL BWP may include coreset#0 by radio frequency retuning, and the centers of the Initial DL BWP and coreset#0 may not be aligned.

Similarly, this process may bring about a certain processing delay, and is applicable to a RedCap terminal that is not delay-sensitive.

Example 3: relationship of Initial DL BWP to SSB (Synchronization Signal and PBCH block ).

SSBs include a primary synchronization signal (Primary Synchronization Signals, abbreviated PSS), a secondary synchronization signal (Secondary Synchronization Signals, abbreviated SSS), and a PBCH (Physical Broadcast Channel ).

The Initial DL BWP of the RedCap terminal may configure a separate SSB, or may multiplex the SSBs of the normal terminal/normal user.

When the Initial DL BWP of the RedCap terminal multiplexes the SSBs of the normal terminal, it may occur that the optimal SSBs of the normal terminal are not within the RedCap BWP of the RedCap terminal and can be solved by means of RF return. I.e. by retuning so that the Initial DL BWP of the RedCap terminal contains the optimal SSB of the normal terminal, the access is removed with the optimal SSB, which is called target SSB, at the time of demodulation.

Example 4: initial UL/DL BWP application scope

The Initial UL/DL BWP configured separately for the RedCap terminal may be used in the Initial random access phase, and may also be used in procedures such as RRC (Radio Resource Control ) setup, RRC recovery, RRC reestablishment, etc. after the Initial random access.
