Description

[0001] This application is a divisional application of the Chinese Patent Application No. 201711107748.1, filed on November 10, 2017, entitled "A Method for Determining Uplink Control Channel Scheduling Unit, Base Station and User Equipment". TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, and in particular to a method for determining uplink control channel scheduling unit, a base station and a user equipment BACKGROUND

[0003] 5G NR (New Radio) is a research project of 3GPP (Third Generation Partnership) which determines a new wireless air interface standard based on OFDM (Orthogonal Frequency Division Multiplexing) and will become the basis of the next generation mobile network.

[0004] In the NR system, the structure of the scheduling unit (for example, slot, hereinafter taking slot as an example) has multiple forms, which can be flexibly configured by the base station, and a typical slot can be composed of one or more of the following parts: downlink transmission part, uplink transmission part, GAP part, and the number of OFDM symbols occupied by each part can be configured. That is, the number of OFDM symbols used for uplink transmission in a slot is variable, and the variable range is 0-14.

[0005] In the NR system, the uplink control channel (Physical Uplink Control Channel, PUCCH) is divided into short PUCCH and long PUCCH, wherein the short PUCCH is mainly used for the user equipment (User Equipment, UE) near the cell center to send timely Acknowledgement / Negative Acknowledgement (ACK / NACK) feedback or other channel state information (Channel State Information, CSI), and is generally located at the last few OFDM symbols of the slot (for example, the last 1 or 2 OFDM symbols of the downlink slot; or the last 1 or 2 OFDM symbols of the uplink slot); or placed in the first few symbols before the uplink data in the slot; the long PUCCH is mainly used for the UE at the cell edge, which occupies more OFDM symbols to improve the transmission coverage of the long uplink control channel. The long PUCCH generally includes 4-14 OFDM symbols, and is allowed to span multiple slots, and the detailed implementation method is still under discussion.

[0006] In the NR system, the PUCCH allows to span multiple slots, for example, one PUCCH needs more uplink OFDM symbols, but there are not enough OFDM symbols in one slot, so more slots are needed to provide enough OFDM symbols. When the base station configures the UE with the PUCCH spanning multiple slots, the base station will inform the UE of the starting slot of the PUCCH and the number of slots that need to be spanned, for example, the base station will inform the UE that the starting slot of the PUCCH spanning multiple slots is slot n and the number of slots that need to be spanned is 4, but since the structure of the slot is dynamically changing, that is, the slot structure after slot n has the following slots as the main slot (the number of downlink OFDM symbols in the slot is more than the number of uplink OFDM symbols), the uplink slot (the number of uplink OFDM symbols in the slot is more than the number of downlink OFDM symbols), the pure uplink slot, the pure downlink slot, the reserved slot, etc., how to select the remaining 3 slots except the starting slot for the UE, there is no effective solution at present.

[0067] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0068] It should be noted that this article uses a slot as an example to illustrate the scheduling unit. The scheduling unit contains several consecutive OFDM symbols and can be a pure uplink scheduling unit, a pure downlink scheduling unit, or a hybrid uplink and downlink scheduling unit. The slot in this article can be a conventional slot; for example, currently, NR specifies that in frequency bands not exceeding 6 GHz, the number of symbols in a slot is 7 or 14 OFDM symbols, and in frequency bands exceeding 6 GHz, the number of symbols in a slot is at least 14, with other values ​​to be determined. The slot in this article can also be a mini-slot (also called a mini-scheduling unit). For example, in NR, the currently defined mini-slot contains symbol data ranging from 1 to the total number of symbols in the slot - 1. Clearly, the number of symbols in a mini-slot varies considerably.

[0069] The various embodiments described below can exist independently, and the technical features of different embodiments can be combined and used in a single embodiment; PUCCH resources not specifically mentioned herein can be short PUCCH resources and / or long PUCCH resources; PUCCH in this document corresponds to the physical uplink control channel (it may also be named according to transmission characteristics, such as uplink control area or uplink control); in the standardization of NR, PUCCH may also be abbreviated to NR-PUCCH or other abbreviations, but its original meaning is still physical uplink control channel, and the content carried has not changed, so the name is not used to limit the scope of protection of this application.

[0070] like Figure 1 As shown, a method for determining an uplink control channel scheduling unit according to the present invention includes the following steps:

[0071] Step 101: the base station configures the user equipment with the number of scheduling units occupied by the uplink control channel of the user equipment, the starting scheduling unit used by the uplink control channel, the starting symbol position in the starting scheduling unit and the number of symbols used by the uplink control channel;

[0073] It should be noted that when the base station has configured the user equipment to receive the scheduling unit type indication signaling from the base station, and the user equipment has not correctly received the scheduling unit type indication signaling from the base station, the scheduling unit type indication signaling is used by the base station to indicate the type of the subsequent scheduling unit of the user equipment, and the determination method further comprises:

[0074] The user equipment only determines the starting scheduling unit as the scheduling unit used by the uplink control channel. At this time, the user equipment only transmits the control information of the uplink control channel in the starting scheduling unit used by the uplink control channel indicated in the scheduling unit indication signaling.

[0075] Further, when the base station does not configure the user equipment to receive the scheduling unit type indication signaling from the base station, the determination of the subsequent scheduling unit used by the uplink control channel according to the agreed rule specifically comprises:

[0076] The base station determines the continuous n scheduling units starting from the starting scheduling unit and including the starting scheduling unit as the scheduling units used by the uplink control channel, wherein n is the number of scheduling units occupied by the uplink control channel.

[0088] It is worth mentioning that the OCC multiplexing capability is calculated as a whole when the uplink control channel does not hop in the determined scheduling unit.

[0089] Further, the subsequent scheduling unit used by the uplink control channel is determined according to the agreed rule, and specifically includes:

[0090] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and the mother code length of the encoded bits of the uplink control channel is the same as the mother code length of the encoded bits of the uplink control channel carried in the starting scheduling unit.

[0099] The user equipment does not determine the subsequent scheduling units, and only determines the starting scheduling unit as the scheduling unit used by the uplink control channel.

[0129] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and the number of uplink symbols capable of carrying the uplink control channel is greater than or equal to the number of symbols used by the uplink control channel in the starting scheduling unit.

[0130] In an embodiment of the present application, the first determining unit 302 determines the position of the symbol used by the uplink control channel in the subsequent scheduling unit according to a predetermined rule, including:

[0131] When the symbol position of the uplink symbol used by the uplink control channel in the subsequent scheduling unit is different from the symbol position of the uplink control channel in the starting scheduling unit, the starting symbol position of the uplink symbol used by the uplink control channel in the subsequent scheduling unit is the first uplink symbol position capable of carrying the uplink control channel.

[0132] Further, the first determining unit 302 determines the subsequent scheduling unit used by the uplink control channel according to a predetermined rule, and the position of the symbol used by the uplink control channel in the subsequent scheduling unit, specifically including:

[0133] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and the number of uplink symbols capable of carrying the uplink control channel is greater than or equal to the number of symbols used by the uplink control channel in the starting scheduling unit, and the symbol position of the uplink symbol used by the uplink control channel in the subsequent scheduling unit is also the same as the symbol position of the uplink control channel in the starting scheduling unit.

[0134] Further, the first determining unit 302 determines the subsequent scheduling unit used by the uplink control channel according to a predetermined rule, including:

[0135] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and carrying the uplink control channel and the starting scheduling unit carrying the uplink control channel have the same OCC multiplexing capability.

[0136] In an embodiment of the present application, the first determining unit 302 determines the subsequent scheduling unit used by the uplink control channel according to a predetermined rule, including:

[0137] When the uplink control channel is frequency hopping, the subsequent scheduling unit has resources capable of carrying the uplink control channel, and satisfies that the superposition OCC multiplexing capability corresponding to each frequency hopping of the uplink control channel in the subsequent scheduling unit is the same as the superposition OCC multiplexing capability corresponding to each frequency hopping of the uplink control channel in the starting scheduling unit.

[0138] It is worth noting that when the uplink control channel is not frequency hopping within the determined scheduling unit, the OCC multiplexing capability is calculated as a whole.

[0139] Further, the first determining unit 302 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, including:

[0140] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and satisfies that the mother code length of the encoded bits of the carried uplink control channel is the same as the mother code length of the encoded bits of the uplink control channel carried by the starting scheduling unit.

[0141] Further, the type of the subsequent scheduling unit only includes uplink scheduling units or downlink scheduling units.

[0142] Further, the type of the subsequent scheduling unit is only an uplink scheduling unit.

[0143] Further, the symbol position used by the uplink control channel in each of the scheduling units is continuous.

[0144] As shown in Figure 4 The application also discloses a user equipment, which comprises a receiving unit 401 and a second determining unit 402, wherein,

[0145] The receiving unit 401 is used for receiving resource configuration signaling from a base station, wherein the resource configuration signaling comprises the number of scheduling units occupied by the uplink control channel, the starting scheduling unit used by the uplink control channel, the starting symbol position of the uplink control channel in the starting scheduling unit and the number of used symbols.

[0146] The second determining unit 402 is used for determining the subsequent scheduling unit used by the uplink control channel and / or the position of the symbol used by the uplink control channel in the subsequent scheduling unit according to the resource configuration signaling and the agreed rule.

[0147] Further, when the base station has configured the user equipment to receive the scheduling unit type indication signaling from the base station, and the user equipment has not correctly received the scheduling unit type indication signaling from the base station, the scheduling unit type indication signaling is used by the base station to indicate the type of the subsequent scheduling unit of the user equipment, and the second determining unit 402 is further configured to:

[0148] not determine the subsequent scheduling unit, and only determine the starting scheduling unit as the scheduling unit used by the uplink control channel.

[0149] It should be noted that when the user equipment has not correctly received the scheduling unit type indication signaling from the base station, the user equipment only sends the control information of the uplink control channel in the starting scheduling unit of the uplink control channel indicated in the scheduling unit indication signaling.

[0150] Further, when the base station has not configured the user equipment to receive the scheduling unit type indication signaling from the base station, the second determining unit 402 is further configured to:

[0151] determine the n continuous scheduling units starting from the starting scheduling unit and including the starting scheduling unit as the scheduling units used by the uplink control channel, wherein n is the number of scheduling units occupied by the uplink control channel.

[0152] It should be noted that when the base station has not configured the user equipment to receive the scheduling unit type indication signaling from the base station, the user equipment sends the control information of the uplink control channel in the n continuous scheduling units starting from the starting scheduling unit of the uplink control channel indicated in the scheduling unit indication signaling.

[0153] Further, the second determining unit 402 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, including:

[0154] the subsequent scheduling unit has resources capable of carrying the uplink control channel, and the number of uplink symbols capable of carrying the uplink control channel is greater than or equal to the number of symbols used by the uplink control channel in the starting scheduling unit.

[0155] In an embodiment of the present application, the second determining unit 402 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, and the position of the symbol used by the uplink control channel in the subsequent scheduling unit, including:

[0156] When the symbol position of the uplink symbol carrying the uplink control channel in the subsequent scheduling unit is different from the symbol position of the uplink control channel in the starting scheduling unit, the starting symbol position of the uplink symbol carrying the uplink control channel in the subsequent scheduling unit is the first uplink symbol position capable of carrying the uplink control channel.

[0157] Further, the second determining unit 402 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, including:

[0159] Further, the second determining unit 402 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, including:

[0160] The subsequent scheduling unit has resources capable of carrying the uplink control channel, and carrying the uplink control channel and the starting scheduling unit carrying the uplink control channel have the same OCC multiplexing capability.

[0161] In an embodiment of the present application, the second determining unit 402 determines the subsequent scheduling unit used by the uplink control channel according to the agreed rule, specifically including:

[0162] When the uplink control channel frequency hops, the subsequent scheduling unit has resources capable of carrying the uplink control channel, and satisfies that the superposition orthogonal code multiplexing capability corresponding to each frequency hopping of the uplink control channel in the subsequent scheduling unit is the same as the superposition orthogonal code multiplexing capability corresponding to each frequency hopping of the uplink control channel in the starting scheduling unit.

[0163] It is worth noting that when the uplink control channel does not hop within the determined scheduling unit, the OCC multiplexing capability is calculated as a whole.

[0168] Further, the symbol position used by the uplink control channel in each of the scheduling units is continuous.

[0169] The embodiments of the present application also provide several preferred embodiments to further explain the present application, but it is worth noting that the preferred embodiments are only for better description of the present application, and do not constitute undue limitation on the present application. The following embodiments can exist independently, and the technical features in different embodiments can be combined in one embodiment for joint use. The PUCCH in this paper corresponds to the physical uplink control channel (also called by transmission characteristics, such as uplink control area or uplink control). In the standardization of NR, PUCCH may also be abbreviated as NR-PUCCH and other abbreviations, but its original intention is still the physical uplink control channel, and the content carried is unchanged, so the name does not affect the method implementation in this paper.

[0170] Preferred embodiment 1

[0171] In this preferred embodiment, when selecting a scheduling unit, the reserved scheduling unit and / or unknown (Unknown) scheduling unit and / or random access channel (Random Access Channel, RACH) scheduling unit after the starting scheduling unit are excluded, and are selected from uplink scheduling units and downlink scheduling units. Among them, the downlink scheduling unit includes pure downlink scheduling unit and downlink dominant scheduling unit. The uplink scheduling unit includes pure uplink scheduling unit and uplink dominant scheduling unit. If it is an uplink dominant scheduling unit, it is required that the number of uplink symbols contained in the uplink dominant scheduling unit meets the requirements. If it is a downlink dominant scheduling unit, it is required that the number of uplink symbols contained in the downlink dominant scheduling unit meets the requirements.

[0172] The base station and the UE respectively derive the scheduling units used by the PUCCH and the mapping of the PUCCH in the derived scheduling units from a starting scheduling unit according to rules. Specifically, the reserved scheduling units and / or Unknown scheduling units and / or RACH scheduling units after the starting scheduling unit are excluded, and the uplink scheduling units and the downlink scheduling units are selected. The downlink scheduling units include the pure downlink scheduling units and the downlink dominant scheduling units. The uplink scheduling units include the pure uplink scheduling units and the uplink dominant scheduling units. If it is the uplink dominant scheduling unit, the number of uplink symbols contained in the uplink dominant scheduling unit is required to meet the requirements. If it is the downlink dominant scheduling unit, the number of uplink symbols contained in the downlink dominant scheduling unit is required to meet the requirements.

[0173] In one carrier, slot n is indicated as the starting slot of the PUCCH, assuming that the PUCCH is configured to require 3 slots and each slot has 4 uplink OFDM symbols to carry the PUCCH. Then the UE also needs to determine the other 2 slots after slot n to carry the PUCCH. In this embodiment, the base station and the UE determine the remaining slots according to the following rules.

[0174] Assuming that if slot n+1 is a reserved slot, the UE will not select it as the remaining slot to carry the PUCCH; if slot n+2 is an Unknown slot, the UE will not select it as the remaining slot to carry the PUCCH; if slot n+3 is an uplink slot and the number of uplink symbols contained meets the requirements, for example, there are 4 consecutive uplink symbols, and if slot n+4 is a downlink slot but the number of uplink symbols contained meets the requirements, for example, there are 4 consecutive uplink symbols, then slot n+3 and slot n+4 are selected as the subsequent slots to carry the PUCCH. In this way, the slots carrying the PUCCH of the UE will have slot n, slot n+3 and slot n+4. It should be noted that the base station also selects the subsequent slots to receive the PUCCH according to the same rules, so the base station should ensure that the symbols of the slots carrying the PUCCH are not used by it.

[0175] The base station is configured with slot type, including the attribute of OFDM symbol in slot, and informs the UE of the configuration information. Therefore, both the base station and the UE are aware of the slot type, the UE selects slot n+3 and slot n+4 as the subsequent slots carrying PUCCH according to the agreed rules, and the base station can also know this. Thus, the UE uses the selected three slots to carry PUCCH and sends it to the base station, and the base station calculates the three slots (actually only the last two slots, the first one is indicated by the base station) selected by the UE according to the agreed rules to receive PUCCH from them.

[0176] The following are two supplementary descriptions for some special cases:

[0177] Supplement 1:

[0178] When the UE does not correctly receive the signaling about the slot type sent by the base station (at present, the base station can inform the UE of the slot type through physical layer signaling downlink control information (DCI), or through high layer signaling), the UE will not be able to determine the slot type, and at this time the UE can only send PUCCH in the slot n indicated by the base station, and the UE no longer determines the slots after slot n. If the base station detects the PUCCH sent by the UE in slot n, and then attempts to receive PUCCH in the subsequent slots selected by the UE, and if it cannot be received, it is considered that the UE has lost the slot type indication signaling.

[0179] Supplement 2:

[0180] If the base station does not configure the UE to receive the slot type signaling (currently the base station can inform the UE whether to receive the slot type configuration information), when the PUCCH is configured to require multiple (for example, 3) slots to carry the PUCCH, the base station indicates the starting slot as slot n, and then the base station needs to configure the OFDM symbols in the multiple (the number of slots required by the PUCCH) consecutive slots after slot n to meet the requirements of carrying the PUCCH. For example, the base station configures the UE's PUCCH to span 3 slots, the base station configures the starting slot as slot n, and the base station needs to configure the number and position of OFDM symbols in slots n+1 and n+2 that carry the UE's PUCCH (if the OFDM position carrying the PUCCH is the same in each slot). When the UE receives the PUCCH and needs to span 3 slots and the starting slot is slot n, the UE considers that the slot carrying the PUCCH starts from the indicated starting slot n, and slots n+1 and n+2 are also slots carrying the PUCCH.

[0181] Preferred Embodiment 2

[0182] In this preferred embodiment, when selecting the scheduling unit, the downlink scheduling unit and / or the reserved scheduling unit and / or the Unknown scheduling unit and / or the RACH scheduling unit after the starting scheduling unit are excluded, and the uplink scheduling unit is selected. Among them, the downlink scheduling unit includes pure downlink scheduling unit and downlink dominant scheduling unit. The uplink scheduling unit includes pure uplink scheduling unit and uplink dominant scheduling unit. If it is an uplink dominant scheduling unit, it is required that the number of uplink symbols contained in the uplink dominant scheduling unit meets the requirements.

[0183] The base station and the UE respectively derive the scheduling unit used by the PUCCH and the mapping of the PUCCH in the derived scheduling unit from the starting scheduling unit according to the rules. Specifically, the downlink scheduling unit and / or the reserved scheduling unit and / or the Unknown scheduling unit and / or the RACH scheduling unit after the starting scheduling unit are excluded, and the uplink scheduling unit is selected. Among them, the downlink scheduling unit includes pure downlink scheduling unit and downlink dominant scheduling unit. The uplink scheduling unit includes pure uplink scheduling unit and uplink dominant scheduling unit. If it is an uplink dominant scheduling unit, it is required that the number of uplink symbols contained in the uplink dominant scheduling unit meets the requirements.

[0184] Preferred Embodiment 2 is similar to Preferred Embodiment 1, except that the downlink scheduling unit is no longer used as a scheduling unit carrying the PUCCH in the multiple scheduling units required by the PUCCH, and the scheduling unit carrying the PUCCH can only be selected from the uplink scheduling unit.

[0185] The specific selection can refer to preferred embodiment 1, which is not repeated here.

[0186] Supplement 1 and supplement 2 in preferred embodiment 1 are also included in preferred embodiment 2, which are not repeated here.

[0187] Preferred embodiment 3

[0188] In this preferred embodiment, when selecting the scheduling unit, it is required that PUCCH contains the same number of symbols and symbol positions in the multiple slots when PUCCH spans multiple slots. If the scheduling unit has the number of symbols and symbol positions that meet the requirements, the scheduling unit is considered as a slot for PUCCH to span multiple slots.

[0189] The base station and the UE respectively derive the scheduling unit used by PUCCH and the mapping of PUCCH in the derived scheduling unit from the starting scheduling unit according to the rules. Specifically, it is required that PUCCH contains the same number of symbols and symbol positions in the multiple slots when PUCCH spans multiple slots. If the scheduling unit has the number of symbols and symbol positions that meet the requirements, the scheduling unit is considered as a slot for PUCCH to span multiple slots. Here, there is no distinction between the types of slots, and only the number of available uplink OFDM symbols and positions in the slot are used as requirements, that is, regardless of the type of slot, as long as the above-mentioned number of symbols and symbol positions are met, it can be used as a subsequent slot to carry PUCCH that spans slots.

[0190] In one carrier, slot n is indicated as the starting slot of PUCCH, assuming that PUCCH is configured to need to span 3 slots, and there are 4 uplink OFDM symbols in each slot (for example, symbols 3-6 in the slot, the symbol number starts from 0, and the slot contains 14 symbols) to carry PUCCH. Then the UE also needs to determine the other 2 slots after slot n to carry PUCCH. In this embodiment, the base station and the UE determine the remaining slots according to the following rules.

[0191] Assume that slot n+1 is a reserved slot, it can be selected as long as it has the required OFDM symbol number and symbol position. Assume that slot n+1 does not have the required OFDM symbol number and symbol position (these symbols are used for NR and allowed to be used for PUCCH, if reserved for other use, these slots are skipped as well), then UE will not select slot n+1 as the remaining slot to carry PUCCH. If slot n+2 is an Unknown slot, UE still judges whether it can be selected as the subsequent slot to carry PUCCH according to the principle of symbol number and symbol position. Assume that slot n+2 does not have the required OFDM symbol number and symbol position. If slot n+3 and slot n+4 both have the required symbol number and symbol position, slot n+3 and slot n+4 are selected as the subsequent slots to carry PUCCH, here it does not matter whether slot n+3 and slot n+4 are of the same type. In this way, according to whether the slot has the required symbol number and symbol position at the same time, slot n+3 and slot n+4 are selected as the subsequent slots to carry PUCCH. In this way, the slots to carry UE's PUCCH will be slot n, slot n+3 and slot n+4, where slot n is indicated by the base station through signaling, and slot n+3 and slot n+4 are selected by the base station and UE according to the agreed rules.

[0192] It should be noted here that the base station also selects the subsequent slots to receive PUCCH according to the same rules, so the base station should ensure that the symbols of the selected slots to carry PUCCH are not used by it.

[0193] The base station is configured with slot types, including the OFDM symbol properties in the slots, and informs the UE of these configurations. So, both the base station and the UE are aware of the slot types, and the UE selects slot n+3 and slot n+4 as the subsequent slots to carry the PUCCH according to the agreed rules, and the base station is also aware of this. Thus, the UE uses the selected three slots to carry the PUCCH and sends it to the base station, and the base station calculates the three slots (actually only the last two slots, the first one is indicated by the base station) selected by the UE according to the agreed rules and receives the PUCCH from them. For the PUCCH to span multiple slots, if there are uplink OFDM symbols in the slots after the starting slot that meet the requirements in terms of the number and / or position of the symbols, the base station ensures that the uplink OFDM symbols in these slots can be used by the PUCCH. Specifically, the base station knows the rules for determining the subsequent slots, so the base station ensures that the uplink OFDM symbols in these slots that will be determined to carry the PUCCH are not used by other channels / data.

[0194] Supplements 1 and 2 in Preferred Embodiment 1 are also included in Preferred Embodiment 3, which will not be repeated here.

[0195] Preferred Embodiment 4

[0196] In this preferred embodiment, when selecting the scheduling unit, it is required that the PUCCH span multiple slots, and the PUCCH contains the same number of symbols in the multiple slots. If a scheduling unit has the required number of symbols, this scheduling unit is considered as a slot for the PUCCH to span multiple slots, but the starting symbol position of the mapping of the PUCCH in this slot is adjusted.

[0197] The base station and the UE respectively derive the scheduling units used by the PUCCH and the mapping of the PUCCH in the derived scheduling units from the starting scheduling unit according to the rules. Specifically, when it is required that the PUCCH span multiple slots, and the PUCCH contains the same number of symbols in the multiple slots. If a scheduling unit has the required number of symbols, this scheduling unit is considered as a slot for the PUCCH to span multiple slots, but the starting symbol position of the mapping of the PUCCH in this slot is adjusted. Here, there is no distinction between the types of slots, and only the number of available uplink OFDM symbols is considered as a requirement (the symbol position is not considered as a requirement), that is, regardless of the type of slot, as long as it meets the above symbol number, it can be used as a subsequent slot to carry the PUCCH that spans slots.

[0198] In one carrier, slot n is indicated as the starting slot of PUCCH, assuming PUCCH is configured to require 3 slots and there are 4 uplink OFDM symbols in each slot to carry PUCCH. Then the UE needs to determine the remaining 2 slots to carry PUCCH after slot n. In this embodiment, the base station and the UE determine the remaining slots according to the following rules.

[0199] Assuming slot n+1 is a reserved slot, it can be selected as long as it has the required number of OFDM symbols. Assuming there is no slot n+1 with the required number of OFDM symbols (these symbols are used for NR and allowed to be used for PUCCH, and if reserved for other use, these slots are skipped), the UE will not select slot n+1 as a remaining slot to carry PUCCH. If slot n+2 is an Unknown slot, the UE determines whether it can be selected as a subsequent slot to carry PUCCH according to the number of symbols. Assuming there is no slot n+2 with the required number of OFDM symbols. If both slot n+3 and slot n+4 have the required number of symbols, slot n+3 and slot n+4 are selected as subsequent slots to carry PUCCH, regardless of the type of slot n+3 and slot n+4. Further, if the required number of OFDM symbols in slot n+3 corresponds to the same symbol position as the symbols used in slot n to carry PUCCH, slot n+3 uses the same symbol position as slot n to carry PUCCH. If the required number of OFDM symbols in slot n+4, but the symbol position is different from the symbol position used in slot n to carry PUCCH. Assuming the number of symbols used in slot n to carry PUCCH is 4 and the symbols are 3-6 (the symbol number in the slot starts from 0), the symbol position used in the selected slot n+3 to carry PUCCH is the same as slot n. Assuming the number of symbols used in slot n+4 to carry PUCCH is also 4, but the symbol position of the uplink symbol is from 4-14, there are 10 uplink symbols, at this time the symbols used to carry the PUCCH are adjusted to start from the first uplink symbol of the slot n+4, a total of 4 consecutive symbols, i.e. symbols 4-7. That is, the symbols used to carry the PUCCH in the selected slot n+4 are 4-7. Obviously, the symbol position used to carry the PUCCH in slot n+4 is adjusted, which is different from the symbol position in slot n and slot n+3. In this embodiment, the adjusted symbol position is implicitly the first uplink symbol in the slot (or known to the UE in the slot), and the adjustment rule is agreed by the base station and the UE in advance.

[0200] Thus, according to whether the number of symbols meeting the requirement in the slot is simultaneously satisfied, slot n+3 and slot n+4 are selected as the subsequent slots to carry the PUCCH, but the symbol position carrying the PUCCH in slot n+4 is adjusted. Thus, the slots carrying the PUCCH of the UE will be slot n, slot n+3 and slot n+4, wherein slot n is indicated by the base station through signaling, and slot n+3 and slot n+4 are selected by the base station and the UE according to the agreed rules.

[0201] It should be noted here that the base station also selects the subsequent slots receiving the PUCCH and the symbol position carrying the PUCCH in the slot according to the same rules, so the base station should ensure that the symbols carrying the PUCCH in the selected slot are not used by it.

[0202] The base station configures the slot type, including the OFDM symbol properties in the slot (uplink symbol, downlink symbol or reserved symbol or GAP symbol, etc.), and notifies the UE of the configuration information. Therefore, both the base station and the UE know the slot type, so the UE selects slot n+3 and slot n+4 as the subsequent slots carrying the PUCCH according to the agreed rules, including adjusting the starting symbol carrying the PUCCH in slot n+4, and the base station can also know the adjusted symbol position according to the agreed adjustment, so the UE uses the selected three slots to carry the PUCCH and sends it to the base station, and the base station receives the PUCCH from the three slots selected by the UE according to the agreed rules (actually only the last two slots, the first one is indicated by the base station). For the PUCCH to be across multiple slots, if there are uplink OFDM symbols meeting the requirement and / or symbol positions in the slots after the starting slot, the base station should ensure that the uplink OFDM symbols in these slots can be used by the PUCCH. Specifically, the base station knows the rules for determining the subsequent slots, so the base station ensures that the uplink OFDM symbols in the slots to be determined to carry the PUCCH are not used by other channels / data.

[0203] Supplement 1 and Supplement 2 in Preferred Embodiment 1 are also included in Preferred Embodiment 4, which will not be repeated here.

[0204] Preferred Embodiment 5

[0205] In the methods described in the above Preferred Embodiments 1-4, the methods in some preferred embodiments can be used in combination without conflict.

[0206] For example, the technical features in preferred embodiment 1 and the technical features in preferred embodiment 3 are combined, then the UE, when selecting a subsequent slot, first excludes the reserved slot and the Unknown slot according to the slot type, and only selects the slot if the number of uplink symbols and the symbol position contained in the downlink slot or the uplink slot after the indicated starting slot are the same as the number of symbols and the symbol position carrying the PUCCH in the starting slot of the PUCCH. The remaining description can refer to preferred embodiment 1 and preferred embodiment 3.

[0207] For example, the technical features in preferred embodiment 2 and the technical features in preferred embodiment 4 are combined, then the UE, when selecting a subsequent slot, first excludes the reserved slot, the Unknown slot and the downlink slot according to the slot type, and only selects the slot if the number of uplink symbols contained in the uplink slot after the indicated starting slot is the same as the number of symbols carrying the PUCCH in the starting slot of the PUCCH. If the uplink symbol position in the slot is different from the symbol position of the PUCCH in the starting slot, the symbol position of the PUCCH in the slot is adjusted according to the agreed rule. The remaining description can refer to preferred embodiment 2 and preferred embodiment 4.

[0208] For example, the technical features in preferred embodiment 1 and the technical features in preferred embodiment 4 are combined, then the UE, when selecting a subsequent slot, first excludes the reserved slot and the Unknown slot according to the slot type, and only selects the slot if the number of uplink symbols and the symbol position contained in the downlink slot and the uplink slot after the indicated starting slot are the same as the number of symbols and the symbol position carrying the PUCCH in the starting slot of the PUCCH. If the uplink symbol position in the slot is different from the symbol position of the PUCCH in the starting slot, the symbol position of the PUCCH in the slot is adjusted according to the agreed rule. The remaining description can refer to preferred embodiment 1 and preferred embodiment 4.

[0209] For example, the technical features in preferred embodiment 2 and the technical features in preferred embodiment 3 are combined, then the UE, when selecting a subsequent slot, first excludes the reserved slot, the Unknown slot and the downlink slot according to the slot type, and only selects the slot if the number of uplink symbols and the symbol position contained in the uplink slot after the indicated starting slot are the same as the number of symbols and the symbol position carrying the PUCCH in the starting slot of the PUCCH. The remaining description can refer to preferred embodiment 2 and preferred embodiment 3.

[0210] In the preferred embodiment, the base station also indicates to the UE which way to determine the subsequent slots when the PUCCH spans multiple slots. For example, if both the way in preferred embodiment 3 and the way in preferred embodiment 4 are supported by the system, the base station can indicate to the UE which way to use to determine the slots that the PUCCH spans through signaling (including high layer signaling or physical layer signaling or medium access control (MAC) layer signaling). The high layer signaling can be a broadcast RRC message or a UE-specific radio resource control (RRC) message. The physical layer signaling can be carried by DCI, including common DCI or UE-specific DCI. The MAC layer signaling can be a control element of the MAC layer. Such indication can increase the robustness of the system.

[0211] Preferred embodiment 6

[0212] Different from the above preferred embodiments 1-5, the preferred embodiment solves the problem of how to determine the number of symbols of the PUCCH in each slot when the PUCCH spans multiple slots if the PUCCH is allowed to have different numbers of OFDM symbols in each slot.

[0213] When the PUCCH (1-2 bit UCI corresponding PUCCH) spans multiple slots, the subsequent slots can be selected as long as the OCC multiplexing capability of the PUCCH is the same as that of the PUCCH in the starting slot. When the PUCCH frequency-hops in a slot, the OCC multiplexing capability is calculated separately for each hop. When the PUCCH does not hop in a slot, the OCC multiplexing capability is calculated as a whole.

[0214] The PUCCH is also divided into different formats according to the number of bits transmitted, but the number of symbols contained is greater than 4. For example, a PUCCH transmission format is set for transmitting 1-2 bits of information in the time domain OCC multiplexing mode (denoted as format 1); a PUCCH transmission format is set for transmitting more than 3 bits and less than X bits in the frequency domain OCC multiplexing mode; and a PUCCH transmission format is set for transmitting more than X bits without supporting multiplexing mode.

[0215] If the above PUCCH formats are transmitted across multiple slots (these formats also apply to embodiments 1-5), the following introduces the case where the number of symbols used to carry the PUCCH in the multiple slots is different. For example, the PUCCH needs to cross 3 slots, but the number of uplink symbols that can be used for the PUCCH in the three slots is not completely equal. For the case where the number of symbols used to carry the PUCCH in the multiple slots is not equal, how to handle it? For example, the first and second slots only have one symbol for the PUCCH, and the second slot has 8 symbols. This PUCCH structure across multiple slots is obviously not optimal. Then, in the case where the number of symbols used to carry the PUCCH in the multiple slots is not equal, how to design the optimal unequal number of symbols? The following introduces a method.

[0216] Generally, for the PUCCH across multiple slots, the base station indicates the starting slot of the PUCCH, and configures the starting symbol and length (number of symbols) in the starting slot, and the number of slots, then how to determine the subsequent slots, and what features do the subsequent slots have to be selected? One way is that for the above PUCCH format 1 (refer to the structure of PUCCH format 1 or 1-2 bits of long PUCCH in the existing NR), when crossing multiple slots, the difference in the number of symbols carrying the PUCCH in each slot is limited by the OCC multiplexing capability. For the selection of the subsequent slot, the basic principle is that when the subsequent slot carries the PUCCH, if the PUCCH has the same OCC multiplexing capability in the slot as carrying the PUCCH in the starting slot, the slot can be selected. If the PUCCH frequency hopping is within the slot, then for the selection of the subsequent slot, the basic principle is slightly changed to that when the subsequent slot carries the PUCCH, if the PUCCH has the same OCC multiplexing capability in the slot as carrying each frequency hopping of the PUCCH in the starting slot, the slot can be selected.

[0217] In an embodiment of the present application, the base station configures a PUCCH for a UE across multiple slots, and informs the UE the starting slot, the starting symbol of the PUCCH in the starting slot, the number of symbols of the PUCCH, the number of slots the PUCCH needs to span, and whether the PUCCH needs to hop or not. Then the base station and the UE agree to determine the slots the PUCCH will use according to the above principles. The UE continues to transmit the PUCCH in the selected slots, and the base station continues to receive the PUCCH in the selected slots. Assume that the base station configures a PUCCH for a UE across 2 slots, the starting slot is slot n, and the PUCCH uses 7 symbols in the starting slot, and the starting symbol is symbol 3 (the symbol index starts from 0), and the PUCCH does not hop. Then for the PUCCH, one more slot is needed. Here, assume that there is no uplink symbol in slot n+1, so slot n+1 is not selected, and there are 6 uplink symbols available in slot n+2, according to Table 1, when the PUCCH does not hop, the OCC multiplexing capability is the same when the number of symbols is 6 or 7, so slot n+2 can be selected to carry the PUCCH. Thus, the slots the PUCCH uses are slot n and slot n+1.

[0218] Further, the selection of the subsequent slots can also consider whether the starting position of the symbols used by the PUCCH in the slots is the same or not. For example, when a strict condition is set, the starting symbol of the PUCCH in the slots is also required to be the same; for example, when a strict condition is set, the starting symbol of the PUCCH in the slots is not required to be the same, in which case only the OCC multiplexing capability needs to be the same, but the starting position of the symbols used by the PUCCH in the slots is agreed, for example, the first uplink symbol available in the slot.

[0219] For the selection of the subsequent slots of the PUCCH configured to span multiple slots, the OCC multiplexing capability of the PUCCH in the selected subsequent slots is the same as that of the PUCCH in the starting slot. In this case, the number of symbols used by the PUCCH in the selected subsequent slots can not be equal to the number of symbols used by the PUCCH in the starting slot, that is, the number of symbols used by the PUCCH in the slots can not be equal to each other (of course, they can be equal). The position of the symbols used by the PUCCH in the selected subsequent slots can also be adjusted, and the adjustment rule can be agreed. In this way, the slots available for the UE to select will be more.

[0220]

[0221] Table 1

[0222] In another embodiment of the application, the agreed principle is that PUCCH supports frequency hopping. When selecting the subsequent slot, the slot needs to satisfy the following condition: if the PUCCH is carried in the slot and frequency hopping is used, the OCC multiplexing capability of the first frequency hop is the same as that of the first frequency hop of the PUCCH in the starting slot, and the OCC multiplexing capability of the second frequency hop is the same as that of the second frequency hop of the PUCCH in the starting slot. In this way, the slot can be selected. If a more stringent condition is set, the starting symbol of the PUCCH carried in the slot can also be set to be the same as the starting symbol of the PUCCH carried in the starting slot.

[0223] Preferred Embodiment 7

[0224] In this preferred embodiment, when selecting the scheduling unit, the PUCCH (for the PUCCH corresponding to more than 3 bits of UCI) spans multiple slots, and the subsequent slot can be selected as long as it satisfies the following requirement: if the PUCCH is carried in the slot, the mother code length of the PUCCH required to be carried in the slot is the same as the mother code length of the PUCCH in the starting slot (the frequency domain resource is the same as that in the starting slot).

[0225] For the PUCCH carrying more than 2 bits of information, since time domain OCC multiplexing is not supported, the principle for selecting the subsequent slot of the PUCCH spanning multiple slots is different. When the PUCCH spans multiple slots, the subsequent slot is selected as long as it satisfies the following condition: if the PUCCH is carried in the slot, the resource (time domain and frequency domain, the time domain is the symbol, and the frequency domain is the PRB) used to carry the PUCCH in the slot carries the mother code length of the encoded bits of the PUCCH, which is the same as the mother code length of the encoded bits of the PUCCH in the starting slot. In this way, the slot can be selected.

[0226] If the strict condition is continued, it can be further required that the frequency domain resource in the resource is not allowed to be increased (i.e. the frequency domain resource used for the PUCCH in the slot is the same as the frequency domain size used for the PUCCH in the starting slot). It can also be further required that the starting symbol of the PUCCH in the slot is the same as the starting symbol in the starting slot. It can also be further required that the code rate of the PUCCH carrying bits in the slot exceeds a certain threshold. Since the code rate is too large when the code bits come from the same mother code length, the decoding performance is reduced, so a reasonable code rate threshold is set to ensure the decoding performance. The threshold of the code rate can be obtained by simulation, or a certain code rate value can be selected from the code rate allowed to be used by the PUCCH. It is emphasized here that the above one or more conditions can be used in combination or alone.

[0227] The application provides a method for determining an uplink control channel scheduling unit, a base station and a user equipment. The method determines the scheduling unit used by the uplink control channel of the user equipment according to an agreed rule, and solves the problem of how to determine which slots to carry the PUCCH after the starting slot when the PUCCH crosses multiple slots. The application provides multiple solutions, which can all determine the slots by using the agreed rule without additional signaling.

[0228] In the present application, the technical features in each embodiment can be combined for use in one embodiment without conflict. Each embodiment is only the optimal implementation of the present application, and does not limit the protection scope of the present application.

[0229] Preferred embodiment 8

[0230] Another problem is described in embodiment 8. The problem is: how to determine the multiplexing mode of the reference signal (De Modulation Reference Signal, DMRS) and data for demodulation when the UE transmits data according to the maximum processing capacity of the UE? The multiplexing mode is time division multiplexing (TDM) or frequency division multiplexing (FDM). The maximum processing capacity of the UE here refers to the minimum time length required for the UE to receive the physical downlink control channel (Physical Downlink Control Channel, PDCCH) scheduling uplink data (including the DMRS required by the data) sent by the base station, decode the PDCCH, and prepare uplink data according to the PDCCH scheduling information, etc. until the uplink data can be sent. Here, it is denoted as N2. The stronger the processing capacity of the UE, the smaller the value of N2. Generally, the value of the capacity of the UE N2 is reported to the base station.

[0231] In practice, since the uplink data transmission is time staggered with the downlink, the base station also configures a TA value for the user to use when transmitting data, so that the user can advance the time unit. Therefore, the minimum distance from the last symbol of the PDCCH scheduling user data to the first data symbol of the PUSCH that the user can actually transmit is related to N2 and TA. The minimum number of symbols from the last symbol of the PDCCH to the first data symbol of the PUSCH can be referred to as K2, which is related to the UE capability N2 and TA, etc. For example, if the last symbol of the PDCCH is at symbol n, and the PUSCH scheduled by the PDCCH for the user starts from symbol n+K2 or n+K2, then the UE has the ability to start transmitting data from n+K2. In order to reduce the complexity of the user or to give the user more time to prepare the transmission of data, it is possible to default to only sending DMRS at the first symbol of the PUSCH, without data. Since the DMRS can be prepared in advance, the user has an additional symbol of time to prepare the transmission of data in the PUSCH.

[0232] However, this default method brings a lot of overhead. Because it is always assumed that the DMRS and data are TDM, i.e. not transmitted at the same time, even if the DMRS does not occupy all the subcarriers of the first symbol, it cannot be used for data transmission.

[0233] A method of limiting the DMRS port multiplexing mode, if the base station dynamically configures the first symbol of the PUSCH to be after K2+X symbols after the last symbol of the corresponding PDCCH, then the multiplexing mode of the DMRS and data of the PUSCH contains FDM and TDM. The multiplexing mode of the PUSCH and the DMRS described herein refers to the multiplexing mode between the first DMRS symbol or the first two consecutive DMRS symbols and the PUSCH.

[0234] If the base station dynamically configures the first symbol of the PUSCH to be at K2+X symbols after the last symbol of the corresponding PDCCH, then the multiplexing mode of the DMRS and data of the PUSCH only contains TDM.

[0235] Optionally, if the base station dynamically configures the first symbol of the PUSCH to be at K2+X symbols after the last symbol of the corresponding PDCCH or before K2+X, and not more than K2 symbols after the last symbol of the PDCCH, then the multiplexing mode of the DMRS and data of the PUSCH only contains TDM.

[0236] If the base station dynamically configures the first symbol of the PUSCH to be before K2+X symbols after the last symbol of the corresponding PDCCH, it is obvious that the user does not have enough time to prepare the transmission of data, so the user will not transmit data this time.

[0237] K2 is calculated based on the user's capability N2.

[0238] Assuming the last symbol of PDCCH is transmitted at symbol n of a slot, after K2 is calculated based on the user's capability N2, the base station should generally schedule the first symbol of the user's PUSCH no earlier than symbol n+K2, otherwise the user does not have enough time to prepare. According to the present application, if the base station configures the first symbol of the user's PUSCH between n+K2 and n+K2+X, the multiplexing of DMRS and data of the PUSCH only contains TDM. Because no data is transmitted on the first PUSCH symbol but only DMRS, the user can win a symbol of preparation time for transmitting data. If the base station configures the first symbol of the user's PUSCH after n+K2+X, the multiplexing of DMRS and data of the PUSCH contains TDM and FDM. At this time, the user has enough time to prepare the transmission of data, and transmitting data on the first PUSCH symbol can effectively improve the resource utilization, where n is an integer.

[0239] When X=0, it becomes that if the base station configures the first symbol of the user's PUSCH at symbol n+K2, no data can be transmitted on the first symbol of the PUSCH, i.e. DMRS and data are TDM. If the base station configures the first symbol of the user's PUSCH after symbol n+K2, data can be transmitted on the first symbol of the PUSCH, i.e. the multiplexing of DMRS and data contains TDM and FDM. If the DMRS on the PUSCH is configured with 2 consecutive DMRS symbols, the multiplexing of DMRS and data on the 2 symbols is the same.

[0240] X is an integer greater than or equal to 0. X can be predefined, such as X being predefined to be equal to 0, or configured to the user by high layer signaling.

[0241] As Figure 5As shown, a total of 4 ports are supported on one DMRS symbol, and are divided into 2 orthogonal Code Division Multiplexing (CDM) groups. Ports p0, p1 correspond to CDM group 0, and ports p2, p3 correspond to CDM group 1. Generally, when the base station assigns port 0 or 1 to a user, the base station needs to tell the user whether there is any other user sending DMRS on CDM group 1. If there is, as shown in the 5th column of Table 2 for index 0, 2, it means that there can be other users sending DMRS on CDM group 1, and then UE 0 cannot send data on CDM group 1. At this time, for UE 0, the DMRS and data are TDM on the symbol of the DMRS. If there is no other user sending DMRS on the CDM group, as shown in Table 2 for index 1, 3, then UE 0 can send data on CDM group 1.

[0242] According to the foregoing, if the base station configures the first symbol of the PUSCH for the user to be between n+K2 and n+K2+X, then index 1, 3 in Table 2 is prohibited. Because the multiplexing mode of the DMRS and data of the PUSCH only contains TDM. Index 1, 3 contains FDM mode. That is, when the base station configures the first symbol of the PUSCH for the user to be between n+K2 and n+K2+X, the user does not want to be configured some DMRS port configurations, which contain data transmission on the symbol of the DMRS. If the base station configures the first symbol of the PUSCH for the user to be after n+K2+X, then there is no restriction.

[0243]

[0244]

[0245] Table 2

[0246] That is, if the base station configures the first symbol of the PUSCH for the user to be between n+K2 and n+K2+X, on the first or first 2 symbols of the PUSCH, all resources other than the resources used for DMRS port transmission for the user are not used for data transmission by the user. If the base station configures the first symbol of the PUSCH for the user to be after n+K2+X, on the first or first 2 symbols of the PUSCH, whether the remaining resources other than the resources used for DMRS port transmission for the user are used for data transmission by the user needs to be indicated by the base station using physical layer dynamic signaling.

[0247] In addition, X, K2, K2+X can be non-negative integers, which are in units of symbols. They can also be non-negative decimals, which are counted in time length, such as nanoseconds.
