AI Technical Summary
In the new wireless communication, in the multi-TTI PDSCH scheduling scenario, using one DCI alone to schedule multiple PDSCHs results in excessive DCI blind inspection overhead, and may cause PDSCH to jump to unavailable RB sets, affecting the normal reception of user equipment.
By sending multiple DCI scheduled PDSCHs in the first format to the user equipment by using the frequency hopping rules and frequency hopping rules available in the downlink bandwidth portion, frequency hopping rules are used to correspond to the available RB set, avoiding frequency hopping to the unavailable RB set.
It effectively reduces the complexity of blind inspection of DCI, ensures that user equipment can successfully receive multiple PDSCHs processed by frequency hopping by the same DCI schedule, and improves communication efficiency.

Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for transmitting a physical downlink shared channel. Background Art
[0002] Currently, in new radio (NR), downlink data is carried on the physical downlink shared channel (PDSCH), and uplink data is carried on the physical uplink shared channel (PUSCH). The base station schedules the PDSCH and PUSCH using downlink control information (DCI) carried on the physical downlink control channel (PDCCH).
[0003] To ensure scheduling flexibility, one downlink control information (DCI) can schedule one PDSCH or one PUSCH.
[0004] When the sub-carrier spacing (SCS) is 960 kHz, the corresponding slot duration is 1 / 64 ms. When the sub-carrier spacing is large and the slot duration is small, if each PDSCH uses a separate DCI scheduling, the DCI blind detection overhead will be too high.
[0005] In a multi-TTI (multi transmission time interval, Multi-TTI) design, one DCI can schedule PDSCH or PUSCH in multiple time slots. Take an example in a multi-TTI PDSCH scheduling scenario to illustrate: one DCI can schedule 4 PDSCHs, and these 4 PDSCHs each correspond to 4 time slots, or 4 PDSCH transmission opportunities. These 4 PDSCHs can be used to transmit different data, that is, to transmit different transport blocks (TBs). The use of a multi-TTI design can reduce the number of DCIs, thereby reducing the complexity of UE blind detection of DCI. Among them, in a multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by a DCI may be semi-statically configured by the upper layer, or it may be dynamically indicated by the scheduling DCI after the protocol indicates a numerical range or the upper layer signaling configures a numerical range.

[0078] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.
[0079] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0080] like Figure 1 As shown, the method for transmitting a physical downlink shared channel provided in an embodiment of the present disclosure can be applied to a wireless communication system 100, which can include a user equipment 101 and a network device 102. The user equipment 101 is configured to support carrier aggregation, and the user equipment 101 can be connected to multiple carrier components of the network device 102, including a primary carrier component and one or more secondary carrier components.
[0081] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.
[0082] The user equipment 101 shown above may be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent or user equipment, etc. The user equipment 101 may have wireless transceiver functions, and may communicate (e.g., wirelessly communicate) with one or more network devices of one or more communication systems and receive network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.
[0083] Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a user equipment in a future 5G network, or a user equipment in a future evolved PLMN network, etc.
[0084] The network device 102 may be an access network device (or access network point). An access network device refers to a device that provides network access functionality, such as a radio access network (RAN) base station. The network device 102 may specifically include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station. The network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.
[0085] For example, the network device 102 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home node B, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.
[0086] When multi-TTI PDSCH scheduling is introduced in the 52.6 to 71 GHz frequency domain of NR, the frequency domain resource allocation strategy may introduce frequency hopping in the frequency domain for multiple PDSCHs scheduled by a single DCI.
[0087] NR-U R16 introduces the concept of resource block sets (RB sets). If higher layers configure RB sets, multiple RB sets are divided in the frequency domain within a bandwidth part (BWP). Network device 102 can indicate to user equipment which RB sets are available for downlink reception and which are not, i.e., which RB sets are available and which are unavailable.
[0088] In the NR 52.6 to 71 GHz frequency domain, when the PDSCH of multiple TTIs is frequency-hopped within a BWP according to the pattern configured by RRC or agreed upon by the protocol, it is possible that one or more of the multiple PDSCHs scheduled by a single DCI will frequency-hop to an RB set indicated as unavailable, thereby affecting the normal reception of the PDSCH by the user equipment 101.
[0089] The present disclosure provides a method for transmitting PDSCH. Figure 2 , Figure 2 FIG. 1 is a flow chart showing a method for transmitting a PDSCH according to an exemplary embodiment. Figure 2 As shown, this method includes:
[0090] In step S21 , the network device 102 sends a plurality of physical downlink shared channels (PDSCHs) scheduled by downlink control information (DCI) in a first format to the user equipment 101 based on a plurality of downlink resource block sets available in the downlink bandwidth portion and a frequency hopping rule.
[0091] In step S22 , the user equipment 101 receives multiple physical downlink shared channels (PDSCHs) scheduled by downlink control information (DCI) in a first format from the network device 102 based on multiple downlink resource block sets available in the downlink bandwidth portion and a frequency hopping rule.
[0092] An embodiment of the present disclosure provides a method for transmitting a PDSCH, which is performed by a network device and includes:
[0093] Based on multiple downlink resource block sets (RB sets) available in the downlink bandwidth portion (BWP) and frequency hopping rules, multiple physical downlink shared channels (PDSCHs) scheduled by downlink control information (DCI) in a first format are sent to the user equipment. In one possible implementation, the downlink bandwidth portion is located in an unlicensed spectrum.
[0094] In a possible implementation manner, the DCI in the first format is DCI1-0, DCI1-1 or DCI1-2.
[0095] In a possible implementation manner, the available multiple downlink resource block sets RB sets are multiple downlink resource block sets RB sets that are indicated by the network device to the user equipment and can be used for downlink reception.
[0096] In the embodiment of the present disclosure, multiple PDSCHs scheduled by the DCI of the first format are sent to the user equipment only on the multiple downlink resource block sets available in the BWP, and the multiple PDSCHs are respectively mapped to the multiple RB sets available in the BWP using the frequency hopping rule, thereby avoiding the situation where the PDSCH is mapped to an unavailable RB set according to the frequency hopping rule, so that the user equipment 101 can successfully receive the multiple PDSCHs scheduled by the same DCI and processed by frequency hopping.
[0097] An embodiment of the present disclosure provides a method for transmitting a PDSCH, which is performed by a network device and includes:
[0098] Determine, based on multiple downlink resource block sets (RB sets) available in the downlink bandwidth part (BWP) and a frequency hopping rule, resource locations of multiple physical downlink shared channels (PDSCHs) scheduled for sending downlink control information (DCI) in a first format;
[0099] At the resource location, multiple PDSCHs scheduled by the DCI in the first format are sent to the user equipment.
[0100] In a possible implementation, the resource locations for sending the multiple PDSCHs scheduled by the DCI in the first format include multiple resource locations, where the multiple resource locations are located in multiple available RB sets.
[0101] In a possible implementation, the resource locations for sending multiple PDSCHs scheduled by the DCI in the first format include multiple resource locations, and each resource location is located in one of the multiple available RB sets.
[0102] In a possible implementation, the resource location is a time-frequency resource location. For example, the time-frequency resource location includes one or more OFDM symbols.
[0103] In the embodiment of the present disclosure, the network device 102 determines the resource location for sending multiple PDSCHs scheduled by the DCI of the first format based on the multiple RB sets available in the BWP and the frequency hopping rules. This resource location is the resource location in the multiple RBsets available in the BWP, so that the multiple PDSCHs scheduled by the DCI of the first format are only sent to the user equipment on the multiple RB sets available in the BWP, avoiding the situation where the PDSCH is mapped to an unavailable RB set according to the frequency hopping rules, so that the user equipment 101 can smoothly receive multiple PDSCHs scheduled by the same DCI and processed by frequency hopping.

In this case, multiple physical downlink shared channels (PDSCHs) scheduled by DCI in the first format are sent to the user equipment on a portion of the available downlink resource block sets (RB sets) in the downlink bandwidth portion (BWP) according to a frequency hopping rule.

That is, multiple physical downlink shared channels (PDSCHs) scheduled by downlink control information (DCI) in a first format are transmitted to the user equipment on all available downlink resource block sets (RB sets) in the downlink bandwidth portion (BWP) according to a frequency hopping rule.
