Abstract
Description
[0001] This application is a divisional application of the original application with the application number: 201710073272.8, the application date: February 6, 2017, and the invention title: "Methods, Apparatuses, Base Stations and User Equipments for Receiving and Transmitting Uplink Control". Technical Field
[0002] The present invention relates to the field of communications, and in particular, to a method, apparatus, base station and user equipment for receiving and transmitting uplink control. Background Art
[0003] The new generation of mobile communication system (New Radio, abbreviated as NR) is being studied and standardized, which is also one of the key focuses of the current 3rd Generation partnership project (3GPP).
[0004] In the currently definable NR system, there will be three typical service types in the future. Common services include: enhanced Mobile BroadBand (abbreviated as eMBB), Ultra-Reliable and Low Latency Communications (abbreviated as URLLC), and massive Machine Type Communications (abbreviated as mMTC). These services have different requirements for latency, coverage, and reliability. For example, for eMBB, high peak transmission rate is mainly emphasized, and there is no high requirement for latency (low latency is not required), and medium reliability is required. For URLLC, low latency and high reliability transmission are emphasized, and the requirement for latency is very strict. For mMTC, a large number of medium terminals, high connection density, and larger transmission coverage are emphasized, and there is almost no requirement for latency.
[0005] The following are some wireless data and control structures designed for the fifth-generation wireless communication technology (5 th -generation, abbreviated as 5G). Figure 1 And Figure 2 are schematic diagrams of the structure of transmission units in the early technical discussions of NR, such as Figure 1As shown, it can be regarded as a basic transmission unit, such as a transmission time interval (TTI) composed of multiple orthogonal frequency division multiplexing (OFDM) symbols, or a subframe composed of multiple TTIs. Among them, downlink control is control information related to downlink data sent by the base station to the user equipment (UE); the guard period (GP) is used to implement the time for the receive / transmit state transition; uplink data is data sent by the UE to the base station; uplink control is feedback information such as acknowledgement (ACK) / non-acknowledgement (NACK) of downlink data reception, channel state information, and scheduling requests sent by the UE to the base station. Information other than uplink data that the UE needs to send to the base station. As Figure 2 shown, it is a basic transmission unit for downlink data transmission. For example, it includes downlink control, downlink data, guard period, and uplink control. The function of each part is the same as that of the corresponding part in Figure 1 the corresponding part.
[0006] Aggregation is allowed between such basic transmission units, that is, multiple basic units are connected in series into a longer transmission unit for data transmission. The intermediate transmission unit can only be data and does not include a control part.
[0007] In a transmission unit, when uplink control is included, it is considered in the prior art that the uplink control includes one OFDM symbol, and this uplink control is called short-form uplink control. Further, in order to support time division multiplexing of uplink controls of different receivers (such as UEs) in a transmission unit, a mechanism is also being considered to indicate to the UE the OFDM symbol where its uplink control is located. That is to say, in a transmission unit, there will be multiple uplink controls, and each uplink control occupies 1 OFDM symbol.
[0008] If there are multiple uplink controls in a transmission unit and each uplink control occupies one OFDM symbol, how to configure the position of the uplink control combined with the beam to make the implementation of the receiver or transmitter simple and the efficiency the highest.
[0009] The following analyzes the possible problems that may exist when time division multiplexing of multiple uplink controls of different receivers exists in a transmission unit.
[0010] Assume (the assumed scenario actually exists, only for the convenience of description) that in a transmission unit, there are two receiving ends. Receiving end 1 needs to transmit uplink data and uplink control, and receiving end 2 only needs to transmit uplink control. Further, assume that receiving end 1 corresponds to beam direction 1, receiving end 2 corresponds to beam direction 2, and the sending end (such as a base station) cannot receive beam directions 1 and 2 simultaneously in one OFDM symbol (there are various reasons for this, such as there is only one radio frequency link in the base station, etc.). Here, it is assumed that each uplink control occupies one OFDM symbol.
[0011] If receiving end 1 transmits uplink data in beam direction 1 in the uplink data part of the transmission unit, when in the transmission unit, the uplink control corresponding to beam direction 2, that is, the uplink control of receiving end 2, is configured in the OFDM symbol immediately following the uplink data (i.e., the penultimate OFDM symbol), and the uplink control corresponding to beam direction 1 is configured in the last OFDM symbol. At this time, the processing of receiving end 1 will become complex. Here, receiving end 1 sends uplink data until the end of the penultimate OFDM symbol, then pauses sending until the end of the penultimate OFDM symbol, and then sends the uplink control again in the last OFDM symbol. At this time, due to reasons such as the insufficient adjustment of the automatic gain control (AGC) of the receiving end, the transmission performance of the uplink control of receiving end 1 will decline (after the device starts sending, the power amplifier level needs to climb before it can send stably), and there will be a gap in the sending of receiving end 1 (such as a gap in the penultimate OFDM symbol), making the implementation of receiving end 1 complex. The processing of the sending end (such as a base station) will also become complex due to the appearance of the gap.
[0012] Therefore, in the related art, the configuration method of the OFDM symbol position of the uplink control of the receiving end has the problem of complex processing. Summary of the Invention

Those of ordinary skill in the art can understand that Figure 3 the structure shown is only schematic and does not limit the structure of the above-mentioned electronic device. For example, the base station 30 may further include more or fewer components than Figure 3 shown, or have a configuration different from Figure 3 shown.

Herein, the physical layer signaling includes downlink control information, and the high layer signaling includes Radio Resource Control (RRC) messages. When both the physical layer signaling and the high layer signaling are used, the high layer signaling configures a predetermined position of the uplink control in the transmission unit, and the predetermined position includes the end position of the transmission unit or the position before transmitting uplink data, and the physical layer signaling configures the OFDM symbol for transmitting the uplink control; step S602 may include: according to the received physical layer signaling and / or high layer signaling, the receiving end determines the OFDM symbol in which the uplink control is located in the transmission unit.
[0150] Optionally, step S602 may include: when the receiving end transmits uplink data in a transmission unit, automatically adjusting the OFDM symbol where the uplink control is located to an OFDM symbol adjacent to the OFDM symbol used for transmitting uplink data in the transmission unit, or automatically adjusting it to at least two consecutive OFDM symbols starting from the OFDM symbol adjacent to the OFDM symbol used for transmitting uplink data in the transmission unit, where consecutive includes: consecutive forward or consecutive backward.
[0151] Optionally, before step S604, it may also be determined the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located; step S604 may include: in the determined OFDM symbol, transmitting the uplink control using the determined beam direction.
[0152] Optionally, determining the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located may include: when receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located, determining that the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located is: the beam direction indicated in the received signaling; or when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located, by default using all or at least one of the beam directions used by the receiving end for transmitting uplink data in the transmission unit; or when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located in the transmission unit, by default using all or at least one of the beam directions used by the receiving end for transmitting uplink data or uplink control in the transmission unit before the current transmission unit; or when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located in the transmission unit, by default using all or at least one of the beam directions used by the receiving end for receiving downlink data in the transmission unit.
[0153] Optionally, the uplink control occupies at least one OFDM symbol; and / or, the uplink control is used to send acknowledgment information / non-acknowledgment information ACK / NACK, channel state information CSI, or beam direction information; and / or, the uplink control is located in the OFDM symbol at the end of the transmission unit, and / or, the uplink control is located in the OFDM symbol before the OFDM symbol used for transmitting uplink data in the transmission unit; and / or, the uplink control is an area for transmitting the physical uplink control channel PUCCH, or an area for transmitting uplink control information UCI.
[0154] Optionally, the transmission unit may be a subframe, a time slot, a mini time slot, etc., and the OFDM symbol may also be a resource unit used to characterize the resource size on other time-frequency resources.
[0155] In this embodiment, a method for transmitting uplink control is further provided. Figure 7 It is the flow of the method for transmitting uplink control according to the embodiment of the present invention. Figure 2 As Figure 7 shown, the flow includes the following steps:
[0156] Step S702: Determine the beam direction used for transmitting uplink control in the orthogonal frequency division multiplexing (OFDM) symbol where the uplink control is located.
[0157] Step S704: Transmit the uplink control using the determined beam direction.
[0158] Through the above steps, the receiving end determines the beam direction that can be used for transmitting uplink control in the OFDM symbol where the uplink control is located, enabling the receiving end to transmit uplink control within the range of available beam directions, solving the problem of complex processing existing in the configuration method of the OFDM symbol position of uplink control in the related art, and reducing the complexity of uplink control processing.
[0159] Optionally, determining the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located may include: when receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located, determining that the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located is the beam direction indicated in the received signaling; or, when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located, defaulting to using all or at least one of the beam directions used by the receiving end for transmitting uplink data in the transmission unit; or, when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located, defaulting to using all or at least one of the beam directions used by the receiving end for transmitting uplink data or uplink control in the transmission unit before the current transmission unit; or, when not receiving a signaling for notifying the receiving end of the beam direction used for transmitting uplink control in the OFDM symbol where the uplink control is located in the transmission unit, defaulting to using all or at least one of the beam directions used by the receiving end for receiving downlink data in the transmission unit.
[0160] Optionally, the uplink control occupies at least one OFDM symbol; and / or, the uplink control is used to transmit acknowledgment information / non-acknowledgment information ACK / NACK, channel state information CSI, or beam direction information; and / or, the uplink control is located in the OFDM symbol at the end of the transmission unit, and / or, the uplink control is located in the OFDM symbol before the OFDM symbol for transmitting uplink data in the transmission unit; and / or, the uplink control is a region for transmitting the physical uplink control channel PUCCH, or a region for transmitting uplink control information UCI.
[0161] Optionally, the transmission unit may be a subframe, a time slot (slot), a mini time slot, etc., and the OFDM symbol may also be a resource unit for characterizing the resource size on other time-frequency resources.
[0162] Based on the above embodiments and preferred implementation manners, to illustrate the entire process interaction of the solution, in this preferred embodiment, a method for receiving uplink control and a method for transmitting uplink control are provided, and the method will be generally described below.
[0163] Refer to Figure 8 , in this preferred embodiment, when the transmitting end (for example, it may be a base station, a small cell base station, a radio frequency remote unit, etc., and in this preferred embodiment, it is described by taking the base station as an example) configures the OFDM symbol position of the uplink control (described by taking PUCCH as an example in this preferred embodiment) for the receiving end (for example, it may be a UE, a terminal, etc., and in this preferred embodiment, it is described by taking the UE as an example) in the transmission unit (for example, it may be a subframe, a time slot (slot), a mini time slot, etc., and in this preferred embodiment, it is described by taking the slot as an example), it should ensure the continuity between the OFDM symbol of the UE's transmitted data (uplink data) and the OFDM symbol for transmitting its PUCCH, so as to avoid a gap between the OFDM symbol of the UE's transmitted data and the OFDM symbol for transmitting its PUCCH when configuring the OFDM symbol position of the UE's PUCCH. Such a gap will increase the additional complexity during the UE's transmission and the base station's reception.
[0164] When multiple beam direction PUCCHs need to be transmitted in a slot, the uplink control with the same beam direction as the data transmitted in the slot is configured in the OFDM symbol adjacent to the data, so as to ensure the continuity of the UE data and uplink control transmission. If the base station has multiple radio frequency links, then different UEs are allowed to simultaneously transmit uplink data in multiple different directions in the slot. When there are multiple beam directions used for transmitting data in the slot, the PUCCH of the UE that is at least consistent with one of the beam directions used for transmitting data in the slot is placed in the OFDM symbol adjacent to the data.
[0165] The uplink control described herein refers to the short PUCCH, which occupies one OFDM symbol in the time domain. If the subsequent short PUCCH is defined to occupy multiple OFDM symbols (e.g., 2, 3, etc.), the method provided in this preferred embodiment is still applicable.
[0166] For UEs that only transmit PUCCH in one slot, the positions of the OFDM symbols for these UEs to send PUCCH can be configured in OFDM symbols that are not consecutive with the OFDM symbols for transmitting data, or can be correspondingly configured according to the beam directions used by each OFDM symbol of the PUCCH.
[0167] The receiving method for uplink control and the sending method for uplink control provided in the preferred embodiment of the present invention can be applied to the position configuration of uplink control, and the method can be summarized as follows:
[0168] When the uplink control of different receiving ends is included in a transmission unit and they are time-division multiplexed, when the sending end configures the OFDM symbol positions of the uplink control for the receiving end in the transmission unit, it should ensure the continuity between the OFDM symbols for the receiving end to transmit uplink data and the OFDM symbols for the receiving end to send uplink control.
[0169] Optionally, the uplink control of one receiving end occupies 1 or 2 OFDM symbols; the uplink control is used to send ACK / NACK, CSI, or beam direction information; the uplink control is located in the OFDM symbols at the end of the transmission unit, and / or the uplink control is located before the uplink data transmitted in the transmission unit; the uplink control refers to the area for transmitting the physical uplink control channel, or the area for transmitting UCI.
[0170] Optionally, the above-mentioned ensuring the continuity between the OFDM symbols for the receiving end to transmit uplink data and the OFDM symbols for the receiving end to send uplink control includes: when multiple beam direction PUCCHs need to be transmitted in one slot, configuring the uplink control with the same beam direction as the data transmitted in the slot in the OFDM symbol adjacent to the data, so as to keep the sending of the uplink control of the UE data continuous.
[0171] Optionally, the above-mentioned ensuring the continuity between the OFDM symbols for the receiving end to transmit uplink data and the OFDM symbols for the receiving end to send uplink control includes: if the base station has multiple radio frequency links, and different UEs are allowed to simultaneously send uplink data in multiple different directions in the slot, when there are multiple beam directions used for transmitting data in the slot, configuring the PUCCH of the UE that is at least one of the same as the beam direction used for transmitting data in the slot in the symbol adjacent to the data; or,
[0172] When there is at least one beam direction in the PUCCH of UEs with different beam directions that is the same as at least one beam direction of the data transmitted in the slot, the transmitting end carries UCI that is the same as at least one beam direction of the beam direction for transmitting uplink data in the PUCCH in the OFDM symbol before or after the OFDM symbol immediately adjacent to the OFDM symbol for transmitting uplink data in the slot; or,
[0173] When the PUCCH resources of multiple UEs in a slot are located in different OFDM symbols, the transmitting end configures the PUCCH of the UE whose beam direction is at least one of the same as the beam direction used for transmitting uplink data in the slot in the symbol immediately adjacent to the symbol for transmitting uplink data;
[0174] Among them, the OFDM symbol configured to transmit the PUCCH is immediately adjacent to one OFDM symbol for transmitting uplink data; or, the OFDM symbol configured to transmit the PUCCH is several consecutive (including forward consecutive or backward consecutive) symbols (such as 2, 3, 4, etc. symbols) starting from the symbol immediately adjacent to the symbol for transmitting uplink data.
[0175] Optionally, making the OFDM symbols for transmitting uplink data and transmitting uplink control at the receiving end continuous includes: when in a slot, the beam direction for transmitting uplink data of the same receiving end is different from the beam direction for transmitting uplink control, the transmitting end configures the OFDM symbol for uplink control of this receiving end in the OFDM symbol immediately adjacent to the OFDM symbol for transmitting uplink data or in several consecutive symbols starting from the OFDM symbol immediately adjacent to the OFDM symbol for transmitting uplink data.
[0176] Optionally, when the transmitting end configures the position of the OFDM symbol for uplink control for the receiving end in the transmission unit, it includes: the transmitting end configures through physical layer signaling and / or high layer signaling; among them, the physical layer signaling includes downlink control information, and the high layer signaling includes RRC messages; when the physical layer signaling and the high layer signaling are used simultaneously, the high layer signaling configures the relative position of the uplink control in the slot (with the same effect as the aforementioned predetermined position), including being at the end of the slot or before transmitting uplink data, and the physical layer signaling configures the OFDM symbol for the uplink control of the receiving end.
[0177] Optionally, when the transmitting end configures the position of the OFDM symbol for uplink control for the receiving end in the transmission unit, it further includes: the transmitting end implicitly or configures the beam direction that can be used for transmitting uplink control in the OFDM where the uplink control is located in the slot, and sends a signaling to notify the receiving end.
[0178] The transmitting end can only execute: implicitly or configure the beam direction that can be used for transmitting uplink control in the OFDM where the uplink control is located in the slot, and send a signaling to notify the receiving end.
[0179] Optionally, the above implies that: when the transmitting end does not send a signaling to notify the receiving end of the beam direction used for transmitting the uplink control in the OFDM symbol where the uplink control is located, the transmitting end defaults that the receiving end uses all or at least one of the beam directions for transmitting the uplink data in this slot; or, when the transmitting end does not send a signaling to notify the receiving end of the beam direction used for transmitting the uplink control in the OFDM symbol where the uplink control is located, the transmitting end defaults that the receiving end uses all or at least one of the beam directions used for transmitting the uplink data or uplink control previously.
[0180] The following is an example to describe in detail the receiving method and transmitting method of the uplink control in the preferred embodiment of the present invention.
[0181] Assume that the base station has only one radio frequency link, that is, the base station can only receive one beam direction at a time. Assume that in a slot, UE1, UE2, and UE3 are scheduled to transmit uplink data. At this time, UE1, 2, and 3 all have uplink control to be transmitted in this slot. In addition, UE4 also needs to transmit uplink control in this slot. In this way, the last 2 OFDM symbols in the slot will be used for uplink control (one OFDM symbol corresponds to one uplink control. If each uplink control occupies 2 OFDM symbols, then 4 OFDM symbols at the end of the slot are required for two uplink controls at this time. It can also be that one uplink control occupies one OFDM symbol and one occupies 2 OFDM symbols. Then 3 OFDM symbols at the end of the slot are required for two uplink controls at this time). Further, the beam directions for UE1, 2, and 3 to transmit uplink data and uplink control are the same and consistent with each other, all being beam direction 1, and the beam direction for UE4 to transmit uplink control is beam direction 2. At this time, since the beam directions used for the uplink control and the uplink data transmission in the slot by UE1, 2, and 3 are the same, the uplink controls of UE1, 2, and 3 should be configured in the OFDM symbol immediately adjacent to the OFDM symbol where UE1, 2, and 3 transmit data, that is, the uplink controls of UE1, 2, and 3 are configured in the second last OFDM symbol in the slot (the uplink data of UE1, 2, and 3 is transmitted until the third last OFDM symbol ends). The uplink control of UE4 is configured in the last OFDM symbol in the slot. In this way, after UE1, 2, and 3 finish transmitting uplink data using beam direction 1, they continuously use beam direction 1 to transmit uplink control, avoiding the occurrence of a gap of one paused OFDM symbol. UE4 uses beam direction 2 to transmit uplink control in the last OFDM symbol.
[0182] In addition, if there is also a UE5, UE5 only sends uplink control in this slot and uses beam direction 1. Although UE5 does not send uplink data in this slot, but the beam direction used by UE5 is the same as that of UE1, 2, and 3, then the uplink control of UE5 is also configured in the penultimate symbol of the slot.
[0183] An example of the ability of the base station to receive simultaneously with multiple radio frequency links is described below.
[0184] Assume that the base station has multiple radio frequency links and simultaneously receives 8 beam directions. Assume that in a slot, UE1 and UE2 are scheduled to transmit uplink data. At this time, both UE1 and UE2 have uplink control to be transmitted in this slot. In addition, UE3 also needs to transmit uplink control in this slot. In this way, the last 2 OFDM symbols in the slot will be used for uplink control (one OFDM symbol corresponds to one uplink control. If each uplink control occupies 2 OFDM symbols, then 4 OFDM symbols at the end of the slot are required for two uplink controls at this time. It can also be that one uplink control occupies one OFDM symbol and one occupies 2 OFDM symbols, then 3 OFDM symbols at the end of the slot are required for two uplink controls at this time). Further, UE1 uses beam direction 1 to transmit uplink data, and UE2 uses beam direction 1 and beam direction 2 to transmit uplink data (UE2 has two radio frequency links, and the two radio frequency links simultaneously transmit uplink data to the base station). In this way, there are 2 beam directions for transmitting data in the slot. Further assume that UE1 uses beam direction 1 to transmit uplink control, and UE2 uses beam direction 1 and 2 to transmit uplink control (transmitting in two beam directions simultaneously in the same OFDM symbol, which is because UE2 has 2 radio frequency links), and UE3 uses beam direction 3 to transmit uplink control. In this way, since at least one of the beam directions used for the uplink control of UE1 and UE2 is the same as one of the beam directions for transmitting data in the slot, the uplink control of UE1 and UE2 is configured in the OFDM symbol adjacent to the OFDM symbol where UE1 and UE2 transmit data, that is, the uplink control of UE1 and UE2 is configured in the penultimate OFDM symbol in the slot (the uplink data of UE1 and UE2 is transmitted until the end of the third-to-last OFDM symbol). The beam direction used for the uplink control of UE3 is not the same as any of the beam directions for transmitting data in the slot, so the uplink control of UE3 is configured in the last OFDM symbol in the slot. In this way, after UE1 finishes transmitting uplink data using beam direction 1, it continuously uses beam direction 1 to transmit uplink control, avoiding the appearance of a gap of one paused OFDM symbol. After UE2 finishes transmitting uplink data using beam direction 1 and 2, UE2 continuously uses beam direction 1 and 2 to transmit uplink control, also avoiding the appearance of a gap of one paused OFDM symbol. UE3 uses beam direction 2 to transmit uplink control in the last OFDM symbol. If UE1 uses continuous transmission of uplink control twice to increase reliability, UE1 can use beam direction 1 to transmit uplink control in the second-to-last OFDM symbol, and then use beam direction 2 to transmit uplink control in the last OFDM symbol. At this time, UE1 is still transmitting continuously. At least one of the beam directions of the uplink control of UE1 is the same as the beam direction of the uplink data, so the configuration position of the uplink control of UE1 also satisfies the method of the preferred embodiment of the present invention, and at least one of the uplink controls of UE1 is in the symbol adjacent to the uplink data.
[0185] In addition, if there is also UE5, UE5 only sends uplink control in this slot, and UE5 uses beam direction 1. Although UE5 does not send uplink data in this slot, but the beam direction used by UE5 is the same as that of UE1 and UE2, then the uplink control of UE5 is also configured in the penultimate symbol of the slot.
[0186] If the uplink control is placed in the OFDM symbol before the uplink data in the slot, for example in Fig. 9(a), the above information sending method of this preferred embodiment is still applicable.
[0187] The following gives several possible examples from different description perspectives.
[0188] Example 1
[0189] When there is PUCCH of UEs with different beam directions in the slot, the sender places the PUCCH of UEs with different beam directions according to the OFDM symbols, and places the OFDM symbols of the PUCCH of UEs with different beam directions according to the following rules:
[0190] When there is a UE with the same beam direction as the beam direction for transmitting uplink data in the slot among the PUCCH of UEs with different beam directions, the sender places the PUCCH of the UE (such as UE1) having the same beam direction as the beam direction for transmitting uplink data in the slot in the OFDM symbol adjacent to the OFDM symbol for transmitting the uplink data (here, adjacent means adjacent between the OFDM symbol for transmitting uplink data and the OFDM symbol for transmitting uplink control, the same below). Specifically, corresponding to Figure 1 、 2 , when the uplink control is placed at the end of the slot, the PUCCH of UE1 is placed in the OFDM symbol adjacent to the OFDM symbol for transmitting the uplink data, or the PUCCH of UE1 starts to be placed backward from the OFDM symbol adjacent to the OFDM symbol for transmitting the uplink data. Corresponding to Fig. 9(a), when the uplink control is placed before the uplink data, the PUCCH of UE1 is placed in the OFDM symbol adjacent to the OFDM symbol for transmitting the uplink data, or the PUCCH of UE1 starts to be placed forward from the OFDM symbol adjacent to the OFDM symbol for transmitting the uplink data. The PUCCH of other UEs (such as UE2) is placed before (corresponding to Fig. 9(a)) or after (corresponding to Figure 1 and Figure 2 ) of the PUCCH of UE1.
[0191] Among them, the above are the same, including exactly the same and partially the same. Partially the same means that at least one of the beam directions corresponding to the PUCCH of UEs with different beam directions is the same as the beam direction for transmitting uplink data in a slot. There may be multiple beam directions for transmitting uplink data. For example, a UE with multiple radio frequency links simultaneously uses two or more beam directions to send data. In this case, there will be two or more beam directions for transmitting uplink data. When a UE (which can be the UE transmitting uplink data in this slot and / or other UEs) sends PUCCH, it may also use multiple beam directions to send simultaneously, but at least one beam direction is the same as one of the beam directions in the data.
[0192] The basic principle is still that when configuring the OFDM symbol position of PUCCH for a UE in a slot, the continuity between the UE transmitting uplink data and its sending PUCCH should be maintained. Do not have a gap between the UE transmitting uplink data and its sending PUCCH when configuring the OFDM symbol position of the UE's PUCCH. This configuration method will cause additional complexity when the UE sends and the base station receives.
[0193] Example 2
[0194] When there are PUCCHs of UEs with different beam directions in a slot, the sending end places the PUCCHs of UEs with different beam directions according to the OFDM symbols, and places the OFDM symbols of the PUCCHs of UEs with different beam directions according to the following rules:
[0195] When there is at least one beam direction in the PUCCH of UEs with different beam directions that is the same as the beam direction of the data transmitted in the slot, the sending end carries the UCI that is the same as at least one beam direction of the beam direction for transmitting uplink data in the PUCCH in the symbol immediately before or after the symbol for transmitting uplink data in the slot.
[0196] Or,
[0197] When there are PUCCHs of multiple UEs in different OFDM symbols in a slot, the base station places the PUCCH of the UE that is the same as at least one of the beam directions used for transmitting uplink data in the slot in the OFDM symbol immediately adjacent to the OFDM symbol for transmitting uplink data (it can also be several consecutive symbols starting from the OFDM symbol immediately adjacent to the OFDM symbol for transmitting uplink data).
[0198] The following are Practical Examples 1 and 2.
[0199] Example 1, the base station has a single radio frequency link.
[0200] Since the base station has a single radio frequency link, only the uplink data in one beam direction is allowed to be transmitted in a slot. In an uplink slot, the base station schedules 10 UEs for uplink data transmission (the 10 UEs are denoted as UE1 to UE10 respectively), and in addition to transmitting the PUCCH (or UCI, the same below) of UE1 to UE10 in the slot, the PUCCH of another 20 UEs (the 20 UEs are denoted as UE11 to UE30 respectively) also needs to be transmitted. Further, UE11 to UE20 use the same beam direction as the uplink data transmitted in the slot when sending PUCCH, and UE21 to UE30 use a beam direction different from the uplink data transmitted in the slot when sending PUCCH.
[0201] Assume that each OFDM symbol can transmit the PUCCH of 20 UEs. At this time, 2 OFDM symbols are required in this uplink slot for PUCCH to transmit the PUCCH of 30 UEs, and among these UEs, some UEs' PUCCH have the same beam direction as the uplink data transmitted in the slot, while some UEs' PUCCH have a beam direction different from the uplink data transmitted in the slot. At this time, the sending end should carry the PUCCH of UE1 to UE20 in the OFDM symbol adjacent to the one transmitting the uplink data in the slot, and carry the PUCCH of UE21 to UE30 in another OFDM symbol.
[0202] In this way, UE1 to UE10 can directly continue to continuously send their own PUCCH after the uplink data transmission ends until the PUCCH transmission ends, and then stop sending (essentially, the PUCCH of the UEs transmitting uplink data in this slot is adjacent to the OFDM symbol of their uplink data, so that the PUCCH and uplink data of the UE are continuously sent). For UE11 to UE20, they directly send PUCCH in the specified symbol, and UE21 to UE30 also directly send PUCCH in the specified symbol.
[0203] If the positions of the symbols where the PUCCH of UE21 to UE30 are located and the symbols where the PUCCH of UE1 to UE20 are located are exchanged (carry the PUCCH of UE21 to UE30 in the OFDM symbol adjacent to the one transmitting the uplink data in the slot, and carry the PUCCH of UE1 to UE20 in another OFDM symbol), this will result in a symbol interval between the data transmission and PUCCH transmission of UE1 to UE20, causing the UE to frequently turn on and off the radio frequency, making the implementation complex.
[0204] If it is assumed that a symbol can carry the PUCCHs of up to 10 UEs at most, then the PUCCHs of the above-mentioned UEs 1 to 10 are placed adjacent to the symbol for transmitting uplink data in the slot, the PUCCHs of UEs 11 to 20 are placed in the OFDM symbol adjacent to the OFDM symbol where the PUCCHs of the first 10 UEs are placed, and the PUCCHs of UEs 21 to 30 are placed in the OFDM symbol adjacent to the OFDM symbol where the PUCCHs of UEs 11 to 20 are placed (at this time, 3 symbols in the slot are used to place the PUCCHs of UEs). In this way, essentially, the PUCCHs of the UEs that send uplink data in this slot are placed adjacent to the OFDM symbols for sending uplink data. In this way, these UEs can continue to send their own PUCCHs after sending the data, without the need to turn off the radio frequency in the middle, making the implementation of the UE simple.
[0205] Example 2, based on Example 1, assume that the base station has multiple radio frequency links and can receive multiple beam directions simultaneously. Obviously, at this time, the uplink data transmitted in the slot can be allowed to be in multiple beam directions as long as the base station can receive simultaneously in these multiple beam directions. At this time, if the beam direction used by the PUCCH of any UE among UEs 1 to 30 is the same as at least one of the beam directions of UEs 1 to 10 transmitting uplink data in the slot, the PUCCH of this UE with the same beam direction can be placed adjacent to the OFDM symbol for transmitting uplink data.
[0206] Instance 3
[0207] The base station semi-statically configures (e.g., configures for the UE through high-layer signaling, RRC messages) the position of the OFDM symbols for transmitting PUCCH. For example, the base station configures the symbol position of the UE's PUCCH (e.g., for periodically transmitting uplink control) in a series of transmission units (such as transmission units with a specified period interval), and sends the configuration information to the UE. Similarly, the UE receives the configuration information and knows the symbol position of its uplink control in a series of transmission units. When the above-mentioned transmission unit is specifically used: 1) If the UE has uplink data in this transmission unit (the uplink data is scheduled by the base station, so the base station knows whether the UE has uplink data in this transmission unit), the base station defaults to adjusting the symbol of the UE's PUCCH in this transmission unit to an OFDM symbol consecutive with the uplink data (or continuing multiple OFDM symbols forward or backward from the OFDM symbol consecutive with the uplink data), and the base station will receive the UE's uplink control in the adjusted OFDM symbol. 2) If the UE has uplink data in this transmission unit (the uplink data is scheduled by the base station, so the base station knows whether the UE has uplink data in this transmission unit), the UE defaults to adjusting the OFDM symbol of its own PUCCH in this transmission unit to an OFDM symbol consecutive with the uplink data (or continuing multiple OFDM symbols forward or backward from the OFDM symbol consecutive with the uplink data), and the UE will send uplink control in the adjusted OFDM symbol.
[0208] At this time, through the default dynamic adjustment of the UE and the base station, the continuity of the symbols of the uplink data and uplink control of the UE in this transmission unit is achieved.
[0209] Example 4
[0210] When the system is deployed in an unlicensed carrier, in a transmission unit, the base station and the UE should make the OFDM symbols of the UE's uplink data and uplink control continuous, so as to ensure that the UE transmits continuously in this transmission unit, avoid an additional execution of the "Listen Before Talk" (LBT) mechanism (a regulation that the device must execute before using the unlicensed carrier to send data) to preempt the right of use and then transmit, so as to ensure that the transmission is executed.
[0211] Therefore, when the system is deployed in an unlicensed carrier, in a transmission unit, when the (short) PUCCHs of different UEs are time-division multiplexed, the base station and the UE should make the OFDM symbols between the uplink data and uplink control information (sent on the PUCCH) continuous. For example, the base station makes it continuous when configuring the uplink control symbols of the UE, or when the base station and the UE have both uplink data and uplink control transmissions in the transmission unit, it is default that the symbols of the UE's uplink control are continuous with the symbols of the uplink data.
[0212] Example 5
[0213] When configuring multiple candidate PUCCH resources for a UE in one slot (usually configured by higher layer signaling), and then selecting a specific PUCCH resource (usually configured by physical layer signaling) for the UE to use in that slot, the base station should configure some of the PUCCH candidate resources among the multiple candidate PUCCH resources to be located in different OFDM symbols (one candidate PUCCH resource is a PUCCH channel). For example, configure at least one candidate PUCCH resource to be located in the symbols consecutive to the uplink data symbol (or continuously forward or backward from the symbol consecutive to the uplink data symbol).
[0214] If in the transmission unit, the base station and the UE find that the UE has both uplink data and uplink control to send at the same time, the base station and the UE default to use the candidate PUCCH resource consecutive to the OFDM symbol of the uplink data as the specific PUCCH resource. Alternatively, the specific PUCCH resource can also be indicated by signaling to be a certain candidate PUCCH resource consecutive to the symbol of the uplink data.
[0215] From the perspective of the base station, when time-division multiplexing of PUCCH symbols of different UEs is included in the transmission unit, when the base station configures candidate PUCCH resources for the UE, at least one candidate PUCCH is configured within (or at the beginning of) the symbols consecutive to the uplink data. When in this transmission unit, the UE has both uplink data and uplink control to send, the base station indicates by signaling or defaults that the specific PUCCH resource of the UE in this transmission unit is a certain or that candidate PUCCH resource consecutive to the uplink data symbol, and receives the uplink control of the UE from the specific PUCCH resource.
[0216] From the perspective of the UE, the UE receives the candidate PUCCH resource configuration information sent by the base station, learns the candidate PUCCH resources. When in this transmission unit, the UE has both uplink data and uplink control to send, the UE receives the indication signaling or defaults that the specific PUCCH resource of the UE in this transmission unit is a certain or that candidate PUCCH resource consecutive to the uplink data symbol, and sends the uplink control of the UE from the specific PUCCH resource.
[0217] Example 6
[0218] In this example, a method for determining the beam direction during uplink control transmission is given, so that the receiving end (such as the UE) can use the correct beam direction to send uplink control in the allocated uplink control resources; when the sending end (such as the base station) receives, it also uses the correct beam direction to receive accordingly.
[0219] The base station configures the allowable beam directions of the OFDM symbols where different PUCCHs are located in a slot, and sends this configuration information to the UE. The base station uses the corresponding beam directions to receive on the OFDM symbols where the PUCCHs are located.
[0220] For example, there are two short PUCCHs in a slot, which are respectively located at the last two OFDM symbols (it is also possible before the uplink data). The base station can configure the second-to-last OFDM symbol to use beam direction 1 (here it can be multiple beam directions. If there are multiple beam directions, the base station needs to have multiple radio frequency links to receive simultaneously), and the last OFDM symbol to use beam direction 2. Then the base station sends the configuration signaling to the UE. For example, it can be sent using semi-static high-layer signaling, so that the configuration information will be valid for a relatively long time. It can also be sent using physical layer signaling, so that the configuration information can be dynamically changed and adjusted.
[0221] The UE receives the above configuration information sent by the base station, and knows the beam directions that can be used by the OFDM symbols of each PUCCH in the slot. After the UE is configured with the positions of the OFDM symbols of the PUCCH, the UE uses the beam direction used by the OFDM symbol to send uplink control to the base station.
[0222] It should be noted that for the same OFDM symbol, the UE may send using beam direction 1, but the base station may receive using beam direction 1 or beam direction 2. The beam direction of the OFDM symbol where the PUCCH is located sent by the base station to the UE is the beam direction definition on the UE side, and the beam direction used by the base station to receive the PUCCH of a certain OFDM symbol is the beam direction definition on the base station side.
[0223] Example 7
[0224] Based on Example 6, another solution is given.
[0225] The base station configures the OFDM symbols where the PUCCHs of different UEs are located in a slot and the allowable beam directions, and sends this configuration information to the UE. The base station uses the corresponding beam directions to receive on the OFDM symbols where the PUCCHs are located.
[0226] For example, there are two short PUCCHs in a slot, respectively located in the last two OFDM symbols (it is also possible before the uplink data). The base station configures the uplink control of UE1 in the penultimate OFDM symbol and uses beam direction 1 (here there can be multiple beam directions. If there are multiple beam directions, the base station needs to have multiple RF links to receive simultaneously), and configures the uplink control of UE2 in the second-to-last OFDM symbol and uses beam direction 2. Then the base station sends the configuration signaling to UE1 and UE2. For example, it can be sent using semi-static high-layer signaling, so that the configuration information will be valid for a relatively long time. It can also be sent using physical layer signaling, so that the configuration information can be dynamically changed and adjusted.
[0227] UE1 and UE2 respectively receive the configuration information sent by the above base station, learn the positions of their uplink control symbols and the beam directions used, and UE1 and UE2 respectively send uplink control to the base station using the configured beam directions at the configured OFDM symbol positions.
[0228] It should be noted that for the same OFDM symbol, when the UE sends, it may use beam direction 1, but when the base station receives, it may use beam direction 1 or beam direction 2. The beam direction of the OFDM symbol where the PUCCH sent by the base station to the UE is defined as the beam direction on the UE side, and the beam direction used by the base station when receiving the PUCCH of a certain OFDM symbol is defined on the base station side.
[0229] Example 8
[0230] In this example, a resource allocation method is provided to adapt to the use of high-frequency band beams.
[0231] When the base station configures multiple candidate resources for the UE, the multiple candidate resources can be located in OFDM symbols (hereinafter referred to as symbols) with different beam directions, so that when indicating the specific candidate resources to be used for the UE, one candidate resource can be selected from the candidate resources corresponding to the beam direction with the demand as the specific resource used by the UE according to the beam direction demand.
[0232] For example, referring to FIG. 9(b), in a time slot (or subframe, etc.), there are multiple channel resources (such as PUCCH channels). Here, it is assumed that each channel resource occupies 1 OFDM (when there are other numbers of symbols, the principle is the same). For example, in the last 2 OFDM symbols at the end of the time slot, each symbol has a PUCCH channel and corresponds to a respective beam direction (or can also correspond to the same beam direction). For example, the penultimate symbol corresponds to beam direction 1, and the second-to-last symbol corresponds to beam direction 2. When the base station configures multiple sets of candidate resources for the UE, it can configure some of the candidate resources in the penultimate symbol corresponding to beam direction 1, configure some of the candidate resources in the second-to-last symbol corresponding to beam direction 2, and send the configuration information to the UE (including the symbol position and beam direction of the candidate resources). In specific use, the base station selects a suitable candidate resource as the specific resource to be used according to the beam direction of the UE's uplink control or uplink data in the current time slot. For example, when the UE needs to use beam direction 1 in this time slot, the base station indicates one of the candidate resources in the penultimate symbol as the specific resource for the UE to use. Another example is when the UE needs to use beam direction 2 in this time slot, the base station indicates one of the candidate resources in the second-to-last symbol as the specific resource for the UE to use.
[0233] The UE receives the signaling sent by the base station to obtain the information of the specific resource to be used (from multiple sets of candidate resources), the corresponding symbol position, and the beam direction, and then uses the corresponding beam direction to send uplink data in the specific resource to be used.
[0234] In this way, since multiple sets of candidate resources are located in symbols with different beam directions, it is beneficial for the base station to select a suitable candidate resource as the specific resource to be used for data transmission according to the beam direction requirements of the UE. If the base station configures multiple sets of candidate resources in symbols with the same beam direction, then when the UE needs specific resources in other beam directions, the UE will not be able to obtain them because the base station does not configure candidate resources in other beam directions.
[0235] Example 9
[0236] In this example, a method for indicating the time domain position of uplink control is provided, and the signaling overhead of this method is small.
[0237] If a UE simultaneously transmits uplink data (such as PUSCH) and uplink control (such as PUCCH) in a certain time slot, the base station only indicates the OFDM symbol position of the UE's uplink control according to the following rules:
[0238] The base station uses dedicated downlink control information (DCI) to indicate the symbol position for uplink control for the scheduled UE. The time slot position does not require explicit signaling indication (thus saving signaling), but the base station defaults that the time slot position where the symbol position of the indicated uplink control is located is the time slot where the uplink data of the UE is located. The downlink control information DCI is the DCI corresponding to the uplink grant information of the UE. The UE receives the downlink control information DCI corresponding to the scheduled uplink data, determines the symbol position for uplink control, and at the same time the UE defaults that the time slot position where the determined symbol position for uplink control is located is the time slot where its own uplink data is located.
