Description

Method, base station and storage medium for allocating PUCCH resources

Technical Field

Background

Currently, the concept of BWP (Bandwidth Part) is introduced in NR (New radio access technology, New generation radio access technology system), and specifically BWP can be understood as the actual operating Bandwidth of UE (User Equipment). In practical implementation, the base station may configure multiple BWPs for the UE simultaneously, and different BWPs may use different sets of bandwidth and air interface parameters, that is, different data may be transmitted based on multiple BWPs. The UE can only activate one BWP at a time, the base station controls the BWP activated by the UE through DCI (Downlink Control Information), and the UE receives and transmits data within the bandwidth range of the activated BWP.

In the multi-BWP configuration, if the UE wants to operate in multiple BWPs, each BWP needs to configure a PUCCH (Physical Uplink Control Channel) resource, but since the UE can only activate one BWP at a time, the PUCCH resources allocated to other inactive BWPs may be wasted if the Physical location of the PUCCH resources allocated to the inactive BWPs is different from the Physical location of the PUCCH resources allocated to the active BWPs.

The invention provides a method for allocating PUCCH resources, a base station and a storage medium, which are used for solving the technical problem that the PUCCH resources are wasted because the base station allocates the PUCCH resources to UE but the UE does not activate BWP in the prior art.

The technical scheme provided by the embodiment of the invention can be suitable for various systems, particularly 5G systems. For example, the applicable system may be a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a long term evolution (long term evolution, LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an LTE-a (long term evolution) system, a universal mobile system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Mobile Access (WiMAX) system, a New Radio network (NR 5) system, etc. These various systems include terminal devices and network devices. The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5GS), and the like.

The terminal device according to the embodiments of the present invention may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, e.g., a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange language and/or data with the Radio Access Network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in the embodiments of the present invention.

The network device related to the embodiment of the present invention may be a base station, and the base station may include a plurality of cells for providing services to the terminal. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to exchange received air frames with Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present invention may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), may be a network device (NodeB) in a Wideband Code Division Multiple Access (WCDMA), may be an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) System, may be a 5G Base Station (gbb) in a 5G network architecture (next evolution System), may be a Home evolved Node B (HeNB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico Base Station), and the like, which are not limited in the embodiments of the present invention. In some network architectures, a network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

Multiple Input Multiple Output (MIMO) transmission may be performed between the network device and the terminal device by using one or more antennas, where the MIMO transmission may be Single User MIMO (SU-MIMO) or Multi-User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of root antenna combinations.

As described above, the base station may configure multiple BWPs (Bandwidth Part) for the UE at the same time, different BWPs may use different sets of Bandwidth and air interface parameters, and the benefits of configuring multiple BWPs for the UE mainly include: 1. providing support for UE with receiver bandwidth smaller than system bandwidth; 2. the power consumption of the UE is reduced by switching among BWPs with different bandwidths; 3. different service types are better supported by switching among BWPs with different air interface parameter sets.

In addition, when each BWP operates, the UE needs to configure a PUCCH (Physical Uplink Control Channel) resource, where the PUCCH resource at least includes, according to the usage: a resource used for SR (Scheduling request) reporting, a resource used for CSI (channel-state information) feedback, and a HARQ (Hybrid automatic repeat request) feedback resource used for PDSCH (Physical downlink shared channel) data.

In an actual implementation process, if a plurality of BWPs are configured for a UE, each BWP needs to configure a PUCCH resource, and since the UE can only activate one BWP at a time, there is a problem that the PUCCH resources allocated on the inactive BWPs are wasted if the physical locations of the PUCCH resources allocated on the inactive BWPs are different from the physical locations of the PUCCH resources allocated on the active BWPs. In addition, if the Physical Resource Block (PRB) positions in the BWP are occupied by PUCCH resources, these PRBs cannot be used for PUSCH (Physical uplink shared channel) transmission, and the uplink data transmission capacity will be affected.

The following is an example of configuring 2 BWPs for a UE, and describes allocation of PUCCH resources in the prior art. Referring to fig. 1, fig. 1 is a schematic diagram illustrating PUCCH resources allocated in the prior art exemplarily shown in an embodiment of the present invention. The base station configures 2 BWPs for the UE, which are BWP1 and BWP2, respectively, and the air interface parameter sets of the two BWPs are the same, where the bandwidth of BWP1 is 273 PRBs, the bandwidth of BWP2 is 78 PRBs, and the interval of the 2 BWP PRBs 0 is 5 PRBs; each BWP independently allocates PUCCH resource for UE1, and the dark grey PRBs are PUCCH resource locations allocated for UE1 on different BWPs.

Specifically, it can be seen from fig. 1 that UE1 is allocated one PUCCH resource location on BWP1 and BWP 2; when the active BWP of the UE1 is BWP1, the dark gray PRB position UE1 on BWP2 is unused, but other UEs cannot occupy, and there is a waste of PUCCH resources. And if the active BWP of the UE1 is switched to BWP2, the dark gray PRB position UE1 on BWP1 is unused, but other UEs cannot occupy, which results in PUCCH resource waste.

In view of this, the embodiments of the present invention provide the following solutions:

referring to fig. 2, an embodiment of the present invention provides a method for allocating PUCCH resources, and the processing procedure of the method is as follows.

Step 201: determining a plurality of partial bandwidths BWP configured for the terminal, and determining resource positions where physical resource blocks PRB respectively corresponding to the plurality of BWPs coincide on a frequency domain.

In the embodiment of the present invention, a plurality of BWPs configured for the terminal may be determined according to actual requirements of the terminal. Then, the same reference point of the physical resource blocks PRB corresponding to the multiple BWPs on the frequency domain may be determined, and based on the same reference point, the starting position difference of the physical resource blocks PRB corresponding to the multiple BWPs on the frequency domain may be determined, and the resource positions where the physical resource blocks PRB corresponding to the multiple BWPs respectively coincide on the frequency domain may be determined according to the starting position difference.

In a specific implementation procedure, the same reference point in the frequency domain of the PRBs corresponding To the multiple BWPs may be determined, and specifically, the frequency domain position of each BWP has the same reference point "offset To Carrier", so that the starting position difference of the PRBs corresponding To the multiple BWPs in the frequency domain may be determined by the same reference point, and the PRB number of each BWP starts from the PRB0, so that it may be determined based on the starting position difference that the PRB0 of any BWP in the multiple BWPs coincides with the actual frequency domain position of the PRB (0+ starting position difference) in the other BWPs, and so on, the resource position where the PRBs corresponding To the multiple BWPs respectively coincide in the frequency domain may be determined.

For example, if the BWPs are 2 BWPs, which are BWP1 and BWP2, respectively, and the bandwidth of BWP1 is 273 PRBs, the bandwidth of BWP2 is 78 PRBs, and the start position difference between BWP1 and BWP2 is 6 PRBs, that is, the actual frequency domain positions of the PRB0 of BWP2 and the PRB6 of BWP1 are coincident, the actual frequency domain positions of the PRB1 of BWP2 and the PRB7 of BWP1 are coincident, and so on, the actual frequency domain positions of the PRBs 0 to PRB77 of BWP2 and the PRBs 6 to PRB83 of BWP1 are coincident. That is, the resource positions to be overlapped are PRB 0-PRB 77 of BWP2 and PRB 6-PRB 83 of BWP 1.

It should be noted that, in the embodiment of the present invention, the number of the multiple BWPs is not limited, and the BWPs in which the determined resource location exists may be all BWPs in the multiple BWPs or some BWPs in the multiple BWPs.

For example, if there are 4 BWPs, respectively BWP1, BWP2, BWP3, and BWP4, then there may be a coincident resource location for BWP1 and BWP2, a coincident resource location for BWP3 and BWP4, a coincident resource location for BWP1 and BWP3, or a coincident resource location for BWP1, BWP2, BWP3, and BWP 4.

Step 202: and allocating the same Physical Uplink Control Channel (PUCCH) resource to at least two BWPs with the overlapped resource position at the overlapped position.

In the embodiment of the present invention, after determining that multiple BWPs have overlapped resource locations, at least two BWPs having overlapped resource locations may be allocated the same physical uplink control channel PUCCH resource at the overlapped locations.

In the embodiment of the present invention, it may be determined whether the overlapped resource positions are the resource positions where the physical resource blocks PRB corresponding to the multiple BWPs respectively overlap in the frequency domain; if yes, allocating physical uplink control channel PUCCH resources for any BWP in the plurality of BWPs at the overlapped resource position, and determining the positions of the physical uplink control channel PUCCH resources configured by other BWPs based on the mapping of the positions of the physical uplink control channel PUCCH resources at the frequency domain positions of other BWPs, wherein the other BWPs are the BWPs except any BWP in the plurality of BWPs with the overlapped resource position.

For example, the BWPs include 4 BWPs, which are BWP1, BWP2, BWP3, and BWP4, and BWP1, BWP2, BWP3, and BWP4 all have overlapped PRBs, so that PUCCH resources may be allocated to any one BWP among BWP1, BWP2, BWP3, and BWP4, and the other BWPs may be mapped according to the PUCCH resources allocated to the BWP, so that the terminal may activate the PRB at the same position in the frequency domain based on the PUCCH resources for data transmission.

Therefore, in the embodiment of the present invention, the BWPs may be heap processed according to the BWPs including the overlapped resource positions, that is, which BWPs of the BWPs have the overlapped resource positions, and then PUCCH resources may be allocated and mapped, so as to avoid the waste of PUCCH resources as much as possible and improve the performance of the system.

In the embodiment of the present invention, if multiple BWPs all have overlapping resource positions, one BWP from among the multiple BWPs may be selected to allocate PUCCH resources, and no restriction is imposed on the specific BWPs to which PUCCH resources are allocated. For example, if the plurality of BWPs include 4 BWPs, and BWP1, BWP2, BWP3, and BWP4 are assigned respectively, the PUCCH resource may be assigned at the resource location where the PRBs corresponding to BWP1 overlap, the PUCCH resource may be assigned at the resource location where the PRBs corresponding to BWP2 overlap, the PUCCH resource may be assigned at the resource location where the PRBs corresponding to BWP3 overlap, or the PUCCH resource may be assigned at the resource location where the PRBs corresponding to BWP1 overlap.

In a specific implementation process, in combination with an actual application of the 5G system, if a BWP with a larger bandwidth and a BWP with a smaller bandwidth are configured for the UE, and the BWP with the larger bandwidth can completely cover the BWP with the smaller bandwidth, PUCCH resource allocation can be performed at the overlapped resource positions of the PRBs corresponding to the BWP with the smaller bandwidth. In such a way, the resources can be regularly distributed, and the subsequent use is facilitated.

Furthermore, if BWP1 and BWP2 include corresponding resource locations that overlap each other and the number of PRBs belonging to the resource locations that overlap each other in the PRBs corresponding to BWP1 is greater than the number of PRBs belonging to the resource locations that overlap each other in the PRBs corresponding to BWP2, PUCCH resources can be allocated to the resource locations that overlap each other in BWP 1.

In the embodiment of the present invention, when there is no overlapped resource location corresponding to all BWPs among the BWPs, PUCCH resources may be allocated to the BWPs with overlapped resource locations on the frequency domain of the physical resource blocks PRB corresponding to the two BWPs.

For example, if the BWPs are 4 BWPs and are BWP1, BWP2, BWP3 and BWP4, BWP1 and BWP2 may include overlapping resource positions, and BWP3 and BWP4 may include overlapping resource positions, that is, the PUCCH resources may be allocated to BWPs having overlapping resource positions in the frequency domain of physical resource blocks PRB corresponding to BWP1 and BWP2, and the PUCCH resources may be allocated to BWPs having overlapping resource positions in the frequency domain of physical resource blocks PRB corresponding to BWP3 and BWP 4.

It can be seen that, in the embodiment of the present invention, if BWP1, BWP2, BWP3, and BWP4 do not all have overlapped resource positions, BWP1, BWP2, BWP3, and BWP4 may be stacked to determine whether there are overlapped resource positions, for example, BWP1 and BWP2 have overlapped resource positions, and BWP3 and BWP4 have overlapped resource positions, so as to allocate PUCCH resources for BWP1, BWP2, and BWP3 and BWP4 that have overlapped resource positions in the frequency domain for the physical PRB blocks corresponding to two BWPs respectively.

Specifically, if the overlapped resource position is a resource position where two physical resource blocks PRB corresponding to two BWPs in the multiple BWPs respectively overlap in the frequency domain, a physical uplink control channel PUCCH resource is allocated to one of the two BWPs at the overlapped resource position, and then the position of the physical uplink control channel PUCCH resource configured by the other BWP is determined based on mapping of the position of the physical uplink control channel PUCCH resource at the frequency domain position of the other BWP in the two BWPs.

In order to better explain PUCCH resource allocation to the overlapped resource locations, a specific example of the method for allocating PUCCH resources according to the embodiment of the present invention is described below.

Referring to fig. 3, fig. 3 is a schematic diagram of PUCCH resource allocation according to the embodiment of the present invention. Specifically, two BWPs are BWP1 and BWP2, respectively, and then the same reference point of BWP1 and BWP2 can be determined, for example, with the position of "Offset To Carrier" as the reference point, the initial position difference between BWP1 and BWP2 in the frequency domain, that is, "PRB Offset between BWP1 and BWP 2" can be determined. Specifically, the difference between the start positions of BWP1 and BWP2 is 5 PRBs, that is, the actual frequency domain positions of the PRB0 of BWP2 and the PRB5 of BWP1 are overlapped, the actual frequency domain positions of the PRB1 of BWP2 and the PRB6 of BWP1 are overlapped, and so on, the PRBs 0 to 77 of BWP2 and the PRBs 5 to 82 of BWP1 are overlapped.

In a specific implementation procedure, when performing PUCCH resource allocation, a PUCCH resource may be allocated to a UE only on BWP2, for example, a PRB3 with a resource position BWP2 is overlapped, and a PUCCH resource position used when the UE1 activates BWP1 is a PRB8, which is a PRB3 on a same frequency domain position on BWP1 on BWP2, that is, on BWP 1.

It can be seen that, since there is only one simultaneous BWP activation, i.e. it is impossible to use 2 BWPs simultaneously, the allocated PUCCH resource is used when BWP2 is activated, and the corresponding PUCCH resource is obtained from the mapped position on BWP2 when BWP1 is activated. It is clear that essentially PUCCH resources on 2 BWPs are one physical resource. Specifically, the PUCCH resource configured on each BWP is configured to the terminal through RRC signaling, and in terms of organization of RRC signaling, each BWP has a set of PUCCH configuration parameters, which may refer to the 3gpp-38.331 protocol, and details thereof are not repeated here.

Through the foregoing PUCCH resource allocation method, it can be seen that when the active BWP of the UE1 is BWP1, the position occupied by the PUCCH is PRB8, and the position of the PUCCH resource on BWP2 is PRB3, that is, PRB3 of BWP2 coincides with PUCCH position PRB8 of BWP1, and therefore does not occupy other PRBs alone, so that there is no waste of PUCCH resources that are not allocated on BWP 2. Similarly, when the active BWP of the UE1 is BWP2, the position PRB3 occupied by the PUCCH and the PUCCH resource position PRB8 on BWP1 coincide with the PUCCH position PRB3 of BWP2, and do not occupy other PRBs separately, so there is no waste of the PUCCH resource allocated on BWP 1. Namely, the problem of PUCCH resource waste in the prior art is solved.
