Description

Uplink control channel determining method and device

Technical Field

The present invention relates to, but not limited to, mobile communications technologies, and in particular, to a method and apparatus for determining an uplink control channel.

Background

New generation mobile communication systems (NR) are being studied, in which there may be 3 typical service types in the future, including: enhanced mobile broadband (eMBB, enhanced Mobile BroadBand) traffic, ultra-reliable and low-latency communication (URLLC, ultra-Reliable and Low Latency Communications) traffic, and large-scale machine communication (mctc, massive Machine Type Communications) traffic. These services have different requirements for latency, coverage, reliability, etc. For example, for the eMBB service, high peak transmission rate is mainly emphasized, the requirement on delay is not high (low delay is not required), reliability is required, and the like. As another example, for URLLC traffic, low latency, high reliability transmissions are emphasized, for which the latency requirements are very demanding. As another example, for mctc traffic, a large number of terminals are emphasized, the connection density is high and more transmission coverage is required, and there is little requirement for time delay.

The uplink control channel in the NR system is divided into a short uplink control channel (short PUCCH) and a long uplink control channel (long PUCCH), where the short PUCCH is generally located at the end of a slot by several orthogonal frequency division multiple access (OFDM) symbols (e.g. 1 or 2 OFDM symbols), and there are related techniques that propose to place the short PUCCH in a slot (which may be understood as a scheduling unit, a slot is just a name), several symbols before uplink data such as the end of a downlink slot or the end of an uplink slot. The long PUCCH is mainly used for timely acknowledgement/negative acknowledgement (ACK/NACK) feedback, and is also used for other Channel State Information (CSI) transmission, mainly for UEs in cell center attachment. The long PUCCH occupies more OFDM symbols, mainly for the UE at the cell edge, and is introduced mainly for coverage of a larger range because the coverage of the long PUCCH is improved after more symbols are used.

In the standard discussion of NR, there is no relevant scheme how the long PUCCH is implemented in detail.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.

In this context, slot is a scheduling unit, which includes a plurality of consecutive OFDM symbols, and may be a pure uplink or downlink scheduling unit, or may be a scheduling unit in which uplink and downlink are mixed. The slots herein may be conventional slots, for example, at present, NR specifies that the number of symbols of slots is 7 or 14 OFDM symbols in a frequency band not exceeding 6GHz, and symbol data of slots is at least 14 in a frequency band exceeding 6GHz, and other values are pending; the slots in the method can also be mini-scheduling units (mini-slots), for example, in NR, symbol data contained in the mini-slots defined at present is (1-total number of symbols of the slots is-1), and obvious variation range of the number of symbols of the mini-slots is large.

The following embodiments may exist independently, and technical features in different embodiments may be combined for use in one embodiment; PUSCH resources herein generally refer to PRB resources, PUCCH resources may be PRBs, OFDM symbols, subcarriers, etc. or any combination thereof; PUCCH resources not specifically described herein may be short PUCCH resources and/or long PUCCH resources; the PUSCH and PUCCH herein correspond to a physical uplink data channel (also referred to as an uplink data or uplink data region according to transmission characteristics), a physical uplink control channel (also referred to as an uplink control region or uplink control according to transmission characteristics), respectively; in the standard formulation of NR, PUSCH and PUCCH may be abbreviated as NR-PUSCH and NR-PUCCH, but they are still meant to be physical uplink data channels and physical uplink control channels, and the bearer content is not changed, so the term is not used to limit the protection scope of the present application.

It should be specifically noted that, the long uplink control channel is merely a name of an uplink control channel, and the technical scheme provided herein is essentially an uplink control channel configuration scheme, which is suitable for any uplink control channel, and is more advantageous in the long uplink control channel. Therefore, those skilled in the art will readily recognize that if the designation of the long uplink control channel is changed, the technical solution provided in the present application is still suitable for configuring an uplink control channel, and the designation is not used to limit the protection scope of the present application.

Currently, there are only some simple conclusions, for example, the load range supported by the long PUCCH is 1 bit to several hundred bits, the long PUCCH can span slots, and the long PUCCH supports at least 4 OFDM symbols.

Fig. 1 is a flowchart of a method for determining an uplink control channel according to an embodiment of the present invention, as shown in fig. 1, including:

step 100: the transmitting end configures parameters of a long uplink control channel, wherein the parameters comprise one of the following modes:

a first mode: the method comprises a first parameter and a second parameter, wherein the first parameter represents the initial slot of a long uplink control channel, and the second parameter represents the number of symbols of the long uplink control channel.

The second mode is as follows: the method comprises a first parameter and a third parameter, wherein the third parameter represents the total slot number of a long uplink control channel or the last slot position.

Wherein the transmitting end may be, for example, a base station.

Alternatively, the starting slot in the first parameter may be: spacing slot number;

wherein, the interval slot number is: the number of intervals between the starting slots and the slots of the downlink data transmission corresponding to the uplink control information carried by the long uplink control channel; or, the number of intervals between the slots of the downlink grant information transmission corresponding to the downlink data corresponding to the uplink control information carried by the long uplink control channel is started.

Optionally, the first parameter value is pre-agreed or configured; a starting OFDM symbol of a long PUCCH in a starting slot of a first parameter description is pre-agreed or configured;

the mapping of the OFDM symbols of the long PUCCH in the slot comprises mapping forwards from the end of the slot or mapping backwards from the front of the slot;

the direction of the mapping is pre-agreed or configured and the mapping is performed starting from the starting OFDM symbol.

Optionally, the long PUCCH start slot represented by the first parameter may be a default, or may be a start symbol configuring the long PUCCH in the start slot.

Optionally, the parameters of the long PUCCH configuration by the transmitting end in this step include:

The transmitting end and the receiving end agree with each other to determine the symbol and slot of the long PUCCH according to the first parameter and the second parameter, and the method specifically comprises the following steps: the OFDM symbols represented by the second parameter are distributed in slots starting and following the slots indicated by the first parameter. Calculating the number of long PUCCH symbols from a first uplink symbol (the number of the long PUCCH symbols comprises uplink reference signal symbols) in a slot indicated by a first parameter or the indicated uplink symbols, and accumulating the number of symbols for the long PUCCH in the subsequent slots until the total number of symbols for the long PUCCH required by a second parameter is reached (actually, in the last slot where the long PUCCH is located, the long PUCCH occupies the first uplink symbols of the slot);

alternatively, the OFDM symbols represented by the second parameter are mapped backward or forward in the scheduling unit, starting from the agreed or indicated uplink symbol.

Optionally, the sign of the long PUCCH represented by the second parameter is: all OFDM symbols of the long PUCCH use the same subcarrier spacing (SCS); or, the frequency domain resource used by the long PUCCH uses the same SCS; alternatively, when the long PUCCH uses the symbol of the short PUCCH region, SCS of the symbol of the short PUCCH region allows SCS different from that of the long PUCCH using the symbol of the non-short PUCCH region; alternatively, when the long PUCCH uses a partial frequency domain resource of the symbol of the short PUCCH region, SCS of the partial frequency domain resource of the symbol of the short PUCCH region allows SCS different from that of the long PUCCH using a symbol other than the short PUCCH region.

Alternatively, in an embodiment of the present invention,

the method further comprises the steps of: the transmitting end configures the scheduling unit composition type of the scheduling unit contained in the long uplink control channel;

wherein the scheduling unit composition type includes one or a combination of the following: an uplink scheduling unit, a downlink scheduling unit and a mini-slot; for example, the scheduling unit composition type is only uplink slot, or only downlink slot, or a mixture of uplink slot and mini-slot, etc.

When the scheduling unit composition type comprises mini-slots, the long uplink control channel symbols comprise uplink symbols in the mini-slots;

when the mini-slot is divided into an uplink mini-slot and a downlink mini-slot, the mini-slot is a scheduling unit, that is, the mini-slot is regarded as a scheduling unit to perform configuration operation on the scheduling unit;

the slots where the long PUCCH is located include uplink slots, and the uplink slots can be continuous uplink slots or discrete uplink slots;

when the uplink slot is a discrete uplink slot, the discrete uplink slot is an uplink slot except for the downlink slot in the slots after the first parameter. If reserved slots exist, the discrete uplink slots are uplink slots except for the downlink slots and the reserved slots in the slots after the first parameter.

Among the plurality of uplink slots where the long PUCCH is located, the symbols used by the same long PUCCH keep the same SCS; or, in the plurality of uplink slots where the long PUCCH is located, the same SCS is used by the frequency domain resource used by the long PUCCH; or, in the multiple uplink slots where the long PUCCH is located, the frequency domain resource used by the long PUCCH uses the same SCS as the data in the slot where it is located.

Optionally, in the embodiment of the present invention, the slot where the long PUCCH is located includes a downlink slot, and at this time, the long PUCCH symbol described by the second parameter includes only an uplink OFDM symbol in the downlink slot.

Further, when the slot of the long PUCCH includes a downlink slot, the long uplink control channel maintains SCS identical to other uplink symbols of the long uplink control channel in an uplink symbol used in the downlink scheduling unit or a frequency domain resource portion used by the long uplink control channel in the uplink symbol.

Alternatively, the long PUCCH symbol may be:

symbols excluding short PUCCH; alternatively, symbols including a short PUCCH; alternatively, the base station configures a slot indicating whether the symbol of the long PUCCH contains the symbol of the short PUCCH region in the scheduling unit.

When the symbol of the long uplink control channel is indicated to contain the symbol of the short uplink control channel region in slot, the configuration information for indication can be sent through a physical layer or a high layer signaling; the physical layer signaling comprises downlink control information; the higher layer signaling includes dedicated radio link control messages; wherein the downlink control information includes uplink/downlink grant information.

Optionally, when the parameter of the long PUCCH configured by the base station is the second manner, the method further includes:

and a fourth parameter, which is used for indicating the number of symbols occupied by the long PUCCH in the last slot.

For example, the first few uplink symbols of the last slot are used as the long PUCCH, or which uplink symbols in the last slot are used as the long PUCCH, or the fourth parameter is omitted, i.e. all uplink symbols (except for the symbols of the short PUCCH, or the symbols also containing the short PUCCH) are used as the long PUCCH by default.

Optionally, when one long PUCCH spans multiple slots and the slots are all uplink slots, the method may include:

the same number of symbols is used in each uplink slot;

or, only the symbols of the short PUCCH are used in each uplink slot;

or, in each uplink slot (except the last slot), using all uplink symbols which are allowed to be used by the long PUCCH and cross the long PUCCH of the slot; (including or not including short PUCCH symbols)

or, the same number of symbols is used in each uplink slot by the long PUCCH of the cross slot;

Or, a long PUCCH across slots uses an even number of symbols in each uplink slot;

or, in each uplink slot, the number of symbols of the long PUCCH always starts from the first uplink symbol of the slot;

or the base station configures the initial symbol of the long PUCCH in the uplink slot.

The above options may be combined when they do not conflict.

or, the frequency domain resource used by the long PUCCH keeps consistent in each slot;

or, the frequency domain resource used by the long PUCCH keeps consistent in the sub-band where the long PUCCH is located in each slot;

Step 201: and the UE determines the configuration of the long uplink control channel according to the obtained parameters.

The present invention also provides a computer readable storage medium storing computer executable instructions for performing the uplink control channel determination method of any one of the present invention.

The uplink control channel determining method according to the embodiment of the present invention is described in detail below with reference to specific embodiments.

The following embodiments may exist independently, and technical features of different embodiments may also be combined in one embodiment. The long PUCCH herein corresponds to a long physical uplink control channel, and may be referred to as a transmission characteristic, for example, a long uplink control region or uplink control; in the standard formulation of NR, PUCCH may be abbreviated as NR-PUCCH, but the PUCCH is still intended to be a physical uplink control channel, and the bearer content is unchanged, so the term is not used to limit the protection scope of the embodiments of the present invention.

In NR, a long uplink control channel (long PUCCH) in the related art is mainly characterized in that: at least 4 symbols, can be transmitted across slots, and the load supported by the PUCCH ranges from 1 bit to several hundred bits, with only a small number of features being discussed. The short uplink control channel (short PUCCH) in the related art is mainly characterized in that: on the symbol at the end of slot (there is also a proposal that one short PUCCH occupies one or 2 symbols in the symbols before uplink or downlink data in uplink or downlink slot), the short PUCCHs of different UEs are allowed to be time division multiplexed, and the characteristics of more short PUCCHs can focus on the discussion of NR. These are not intended to limit the scope of the embodiments of the present invention.

In the first embodiment, the base station configures a first parameter and a second parameter of a long PUCCH for the UE, and sends the first parameter to the UE through physical layer signaling, for example, the base station carries the first parameter in downlink grant information (DCI) and sends the UE, and simultaneously sends the second parameter to the UE through the DCI or through higher layer signaling.

In the first embodiment, it is assumed that the base station and the UE agree that the long PUCCH starts with the first uplink symbol (including or not including the symbol of the uplink reference signal corresponding to the long PUCCH) in the slot described by the first parameter; or the base station and the UE agree that the long PUCCH is mapped in the last slot from the first uplink symbol of the slot; alternatively, the base station and the UE agree that the long PUCCH is transmitted only in the uplink slot and does not include symbols of the short PUCCH.

In this way, the base station and the UE can calculate according to the configuration of the first parameter and the second parameter, the conventions of the base station and the UE, and the obtained slot structures (i.e. which slots are uplink slots, and the uplink symbols of the slots, and the symbol number of the short PUCCH): slots occupied by long PUCCHs, and symbols used by long PUCCHs in each slot. That is, the UE receives the first parameter and the second parameter, and according to the above convention and the structure of slots, the slots occupied by the long PUCCH and the symbols occupied in each slot can be calculated.

The second embodiment differs from the first embodiment in that: assuming that the first parameter is implicitly notified, the method specifically includes: the first parameter is indicated as: and the UE sends slots corresponding to the feedback ACK/NACK according to the downlink data scheduled by the received downlink authorization information. This may reduce signaling overhead.

In the third embodiment, based on the first embodiment, it is assumed that, when the number of symbols occupied by the long PUCCH in the last slot does not exceed the number of symbols occupied by the short PUCCH in the slot, by the base station and the UE agree, the symbols occupied by the long PUCCH in the last slot are mapped to the short PUCCH field. This approach is advantageous for implementing the case of only the short PUCCH region in the slot, and thus, when there are more short PUCCH resources, it is advantageous to fully utilize the resources of the short PUCCH region.

Of course, the base station and UE engagement in this embodiment may also be configuration performed by the base station according to the requirement. Such as: when the base station discovers that the short PUCCH in the last slot of the long PUCCH has usable resources, the base station configures the long PUCCH to occupy the symbol of the short PUCCH in the last slot, otherwise, the base station configures the symbol which does not occupy the short PUCCH.

In the fourth embodiment, it is assumed that a base station is agreed with a UE, or the base station configures that if a long PUCCH appears in a downlink slot, a symbol of a short PUCCH region in the slot is included and used as a PUCCH. For example, the base station configures a starting slot of a long PUCCH and a total number of symbols for the UE, the total number of symbols being 4 symbols. The base station and the UE agree that the slot of the long PUCCH span contains a downlink slot. In this embodiment, assuming that the starting slot is one downlink slot and still is one downlink slot after that, then, the symbol occupied by the long PUCCH of the UE is determined according to the first manner as the symbol of the short PUCCH in the starting slot and the slots after the starting slot (here, it is assumed that there are 2 symbols in each of the short PUCCH in the starting slot and the next slot). That is, the long PUCCH may be aggregated using short PUCCH symbols in one or more slots downstream.

In the fifth embodiment, corresponding to the use of the second mode, it is assumed that the base station configures the first parameter or implicitly (the implementation of implicitly is the same as that of the second embodiment 2) for the UE long PUCCH, and the third parameter is configured as 3 slots. And the base station and the UE are assumed to agree that the long PUCCH is only in the uplink slot and does not occupy the short PUCCH symbol. In this embodiment, the base station is further configured with a value of a fourth parameter, which describes the number of symbols occupied by the long PUCCH in the last slot. It should be noted that, if the long PUCCH configured by the base station for the UE occupies all uplink symbols except the short PUCCH symbol in the last slot, the fourth parameter may not be transmitted or may be transmitted. The other parts may be implemented in the manner referred to in the first embodiment. In this way, the UE receives the first parameter, the third parameter and the fourth parameter from the base station, and calculates the slot and the symbol of the long PUCCH according to the first parameter, the third parameter and the fourth parameter and the convention.

A sixth embodiment, based on the foregoing first to fifth embodiments, after determining the number of long PUCCH symbols, the UE generally uses a part of frequency domain resources in the frequency domain, and then, for the same long PUCCH in the frequency domain resources, the base station and the UE may process in one of the following ways:

(1) The long PUCCH of the same UE maintains the same subcarrier spacing SCS in all OFDM symbols in all slots; or,

(2) The long PUCCH of the same UE maintains the same SCS in all OFDM symbols in one slot, and the used OFDM symbols in different slots allow different SCSs; or,

(3) The long PUCCH of the same UE maintains the same frequency domain resource size in different slots. Wherein, for the case of frequency hopping, the same frequency hopping pattern is provided in different slots. For example, the same frequency hopping pattern is provided in different slots, and a specific case is: and if one long PUCCH occupies 2 uplink slots, the first 1-N symbols of the long PUCCH in the first slot are positioned in a frequency domain 1, (n+1) -N symbols are positioned in a frequency domain 2, and the first 1-M symbols of the long PUCCH in the second slot are positioned in the frequency domain 1, (m+1) -M symbols are positioned in the frequency domain 2. Wherein N may be equal to or different from M, and N may be equal to or different from M; or,

(4) The long PUCCH of the same UE is configured in the same one subband in different slots. The long PUCCH is frequency hopped within each subband. For example, one case is: one long PUCCH occupies 2 uplink slots, and the same sub-bands are used in the two slots, then the first 1-N symbols of the long PUCCH in the sub-band in the first slot are positioned in a frequency domain 1 in the sub-band, and the (n+1) -N symbols are positioned in a frequency domain 2 in the sub-band; the first 1-M symbols of the long PUCCH in the second slot are located in the intra-subband frequency domain 1, and the (m+1) -M symbols are located in the intra-subband frequency domain 2. N may be equal to or different from M, and N may be equal to or different from M; or,

(5) The long PUCCH of the same UE is configured in the same plurality of subbands in different slots. The long PUCCH is frequency hopped within each subband or within a bandwidth (referred to as a new subband) that is constructed from the sum of multiple subbands. For example, the long PUCCH occupies 2 uplink slots, and there are 2 subbands in each slot, and the subbands in the 2 slots are the same, so frequency hopping in each subband may be described in parameter (4). The sum of the plurality of sub-bands forms the frequency hopping within the bandwidth, which can be: the first 1 to N symbols of the long PUCCH in the first slot are located in the frequency domain 1 of the new subband, the (n+1) to N symbols are located in the frequency domain 2 of the new subband, and the first 1 to M symbols of the long PUCCH in the second slot are located in the frequency domain 1 of the new subband, the (m+1) to M symbols are located in the frequency domain 2 of the new subband. N may be equal to or different from M, and N may be equal to or different from M; or,

(6) The long PUCCH of the same UE is configured in different frequency bands in different subbands or subbands. The number or number of subbands included in different slots is different. In different slots, each sub-band can independently frequency hop, or after a plurality of sub-bands form a new sub-band, frequency hop is performed in the new sub-band.

In the seventh embodiment, the base station should indicate, for the UE, a slot composition type included in the long PUCCH symbol, where the slot composition type specifically includes: conventional downlink slot, conventional uplink slot, downlink mini-slot and uplink mini-slot. Or indicates that the long PUCCH symbol of the UE allows or does not allow the use of the slot component types, so that the UE definitely knows that the symbols in the slots are included when calculating the long PUCCH symbol, thereby avoiding the situation that the UE misunderstands and miscalculates the symbols of the non-allowed slot component types in the long PUCCH symbol.

In this embodiment, the base station configures, for the UE, whether the symbol of the long PUCCH includes a downlink slot, and the configuration information is sent to the UE through a higher layer signaling or a physical layer signaling. The physical layer signaling includes DCI information, and may be carried by using downlink grant information DCI corresponding to downlink data corresponding to ACK/NACK corresponding to a long PUCCH; the higher layer signaling includes a point-to-point RRC message or a broadcast-type message, and if the broadcast-type RRC message is used, the configuration is validated for a plurality of UEs; if a point-to-point RRC message is used, the configuration is valid for only one UE. Here, when the symbols of the long PUCCH include symbols of the downlink slot, the symbols of the short PUCCH region in the downlink slot are used by default.

In this embodiment, the base station configures the composition type of slots used by the long PUCCH for the UE, for example, only uplink slots are used, or uplink slots and downlink slots are used in a mixed manner, or only downlink slots are used; the configuration information may be transmitted through higher layer signaling or physical layer signaling. The physical layer signaling may include DCI information, and may be carried using downlink grant information DCI corresponding to downlink data corresponding to ACK/NACK corresponding to a long PUCCH; the higher layer signaling may include a point-to-point RRC message or a broadcast-type message, and the configuration is valid for a plurality of UEs if the broadcast-type RRC message is used, and is valid for only one UE if the point-to-point RRC message is used. Here, when the slot composition type used for the long PUCCH includes a downlink slot, a symbol of a short PUCCH region in the downlink slot is used by default.

In this embodiment, the base station configures, for the UE, whether the symbols used by the long PUCCH include symbols of the short PUCCH area, where the configuration may be divided into two cases, for example, whether the symbols of the short PUCCH area include uplink slots, and further, whether the symbols of the short PUCCH area include downlink slots; the configuration information may be transmitted through higher layer signaling or physical layer signaling. The physical layer signaling includes DCI information, and may be carried by using downlink grant information DCI corresponding to downlink data corresponding to ACK/NACK corresponding to a long PUCCH; the higher layer signaling may include a point-to-point RRC message or a broadcast-type message, and the configuration is valid for a plurality of UEs if the broadcast-type RRC message is used, and is valid for only one UE if the point-to-point RRC message is used.

The base station configures the UE with the constituent types of slots used by the long PUCCH (e.g. including mini-slots), and the configuration information can be transmitted through higher layer signaling or physical layer signaling. The physical layer signaling includes DCI information, and may be carried using downlink grant information DCI corresponding to downlink data corresponding to ACK/NACK corresponding to a long PUCCH. The higher layer signaling includes a point-to-point RRC message or a broadcast-type message, and if the broadcast-type RRC message is used, the configuration is valid for a plurality of UEs, and if the point-to-point RRC message, the configuration is valid for only one UE. When the slot composition type used by the long PUCCH comprises a mini-slot, the mini-slot is processed according to the conventional slot by default, because the structure of the mini-slot is the same as that of the conventional slot at present (the conventional slot processing comprises the various processing modes

In the above embodiments, the configuration modes may be used in combination without collision. For example, the base station may configure that the symbols of the long PUCCH do not include the symbols of the short PUCCH region in the uplink slot, but include the symbols of the short PUCCH region in the downlink slot, and so on.
