The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and cannot be understood as limiting the present disclosure.
[0088] In view of the above problems, the present disclosure provides a transmission method, apparatus and communication device for a hybrid automatic repeat request (HARQ).
[0089] Figure 1 A flow chart of a hybrid automatic repeat request HARQ transmission method provided by an embodiment of the present disclosure is provided. The hybrid automatic repeat request HARQ transmission method can be applied to a user equipment UE.
[0090] The terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a UE. The wireless terminal device may communicate with one or more CNs (Core Networks) via a RAN (Radio Access Network). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a wireless access network.
[0091] For example, the terminal device may be a PCS (Personal Communication Service) phone, a cordless phone, a SIP (Session Initiated Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), etc. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, which is not limited in the embodiments of the present disclosure.
[0092] like Figure 1 As shown, the hybrid automatic repeat request HARQ transmission method may include the following steps:
[0093] Step 101: receiving a plurality of downlink semi-persistent scheduling physical downlink shared channel SPS PDSCH resources.
[0094] SPS means that after a UE applies for a resource once, the corresponding resource is periodically allocated to the user within a period of time.
[0095] In the disclosed embodiment, the UE may receive multiple downlink SPS PDSCH resources sent by a network side device.
[0096] Step 102: Perform joint reporting from multiple SPS PDSCH resources with N as a granularity, where N is a positive integer greater than 1.
[0097] In the disclosed embodiment, after receiving multiple SPS PDSCH resources, the UE may perform joint reporting from the multiple SPS PDSCH resources with N as the granularity.
[0098] In a possible case, N SPS PDSCH resources may be grouped and bundled by a network-side device.
[0099] As an example, assuming that N is 5, the network side device may bundle 5 consecutive SPS PDSCH resources, and then these 5 SPS PDSCH resources perform HARQ-ACK feedback together.
[0100] In another possible case, N may be specified by the protocol and may be one or more candidate values.
[0101] As an example, the protocol may specify a fixed N value, such as the protocol specifies that N is 4. For another example, the protocol may specify a candidate N set, such as N={2, 4, 6, 8}.
[0102] In another possible case, the N value may also be determined by the network side device in the form of a display indication.
[0103] In yet another possible case, the N value may also be determined by implicit indication.
[0104] The network side device takes a base station as an example. The base station may include multiple cells that provide services for terminal devices. Depending on the specific application scenario, each cell may include multiple TRPs (Transmitting receiving points), or may be a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. For example, the base station involved in the embodiments of the present disclosure may be a BTS (Base Transceiver Station) in GSM (Global System for Mobile communications) or CDMA (Code Division Multiple Access), or a base station (NodeB) in WCDMA (Wide-band Code Division Multiple Access), or an evolved Node B (eNB or e-NodeB for short) in an LTE (long term evolution) system, or a 5G base station (gNB for short) in a 5G network architecture (next generation system), or a HeNB (Home evolved Node B), a relay node, a femto, a pico, etc., but is not limited in the embodiments of the present disclosure.
[0105] The transmission method of the hybrid automatic repeat request HARQ of the embodiment of the present disclosure receives multiple SPS PDSCH resources through the UE, and jointly reports from the multiple SPS PDSCH resources with a granularity of N. Since the HARQ-ACK feedback is jointly reported from the multiple SPS PDSCH resources with a granularity of N, it is beneficial to reduce the HARQ-ACK feedback overhead.
[0106] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0107] The present disclosure provides another HARQ transmission method. Figure 2 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The hybrid automatic repeat request HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0108] like Figure 2 As shown, the HARQ transmission method may include the following steps:
[0109] Step 201: Receive a candidate value set sent by a network-side device.
[0110] The candidate value set includes multiple candidate values.
[0111] In the embodiment of the present disclosure, the network side device may determine N by displaying an indication, or indicate multiple candidate values included in the candidate value set by displaying an indication.
[0112] In a possible case, the network side device may use RRC (Radio Resource Control) parameters to configure the candidate value set.
[0113] In another possible case, the network side device may also use MAC (Medium Access Control, media access control) CE (Control Element, control element) parameters to configure the candidate value set.
[0114] In another possible case, the network side device may also use DCI (Downlink Control Information) parameters to configure the candidate value set.
[0115] It should be explained that the above-mentioned method of configuring the candidate value set is only described as an example, and any achievable method is applicable to this embodiment and is not limited here.
[0116] Step 202: Receive a first configuration signaling sent by a network-side device, and select N from a plurality of candidate values according to the first configuration signaling.
[0117] In the embodiment of the present disclosure, after the UE receives the first configuration signaling sent by the network device, it can select N from multiple candidate values according to the first configuration signaling.
[0118] As an example, assuming that the candidate value set is N={2, 4, 6, 8}, after receiving the first configuration signaling, the UE can determine that N is 6 from the candidate value set.
[0119] Among them, N has various indicated granularities.
[0120] In the embodiment of the present disclosure, the first configuration instruction is used to indicate one or more UEs.
[0121] The one or more UEs include at least one of the following: a single SPS PDSCH configuration of a single UE; a single UE; multiple UEs in a group; and multiple UEs in a cell.
[0122] The HARQ transmission method of the disclosed embodiment receives a candidate value set sent by a network side device, receives a first configuration signaling sent by the network side device, and selects N from multiple candidate values according to the first configuration signaling. Thus, N is determined in an explicit manner, and HARQ-ACK feedback is jointly reported with N as the granularity from multiple SPS PDSCH resources, which is conducive to reducing HARQ-ACK feedback overhead.
[0123] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0124] The present disclosure provides another HARQ transmission method. Figure 3 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0125] like Figure 3 As shown, the HARQ transmission method may include the following steps:
[0126] Step 301: Acquire the period of SPS PDSCH resources.
[0127] In the embodiment of the present disclosure, N may also be determined by implicit indication.
[0128] In the disclosed embodiment, N may be bound to the period of the SPS PDSCH resources, thereby obtaining the period of the SPS PDSCH resources.
[0129] Step 302: Determine N according to the period of the SPS PDSCH resources.
[0130] In the embodiment of the present disclosure, after the period of the SPS PDSCH resource is acquired, N can be determined according to the period of the SPS PDSCH resource. Thus, N is determined in an implicit manner.
[0131] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0132] The present disclosure provides another HARQ transmission method. Figure 4 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0133] like Figure 4 As shown, the HARQ transmission method may include the following steps:
[0134] Step 401, obtaining the location of physical uplink control channel PUCCH resources.
[0135] In the embodiment of the present disclosure, the UE may obtain the location of a PUCCH (Physical Uplink Control Channel) resource, wherein the location of the PUCCH resource carries indication information indicating N.
[0136] Step 402: Indicate N according to the location of the PUCCH resource.
[0137] In the embodiment of the present disclosure, after the UE obtains the location of the PUCCH resource, it can determine N according to the location of the PUCCH resource.
[0138] As an example, assuming that N bound to the position of the PUCCH resource is 4, N can be indicated as 4 according to the position of the PUCCH resource.
[0139] Thus, it is achieved that N is indicated in an implicit manner, and further, HARQ-ACK feedback is jointly reported from multiple SPS PDSCH resources with N as the granularity, which is conducive to reducing HARQ-ACK feedback overhead.
[0140] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0141] The present disclosure provides another HARQ transmission method. Figure 5 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0142] like Figure 5 As shown, the HARQ transmission method may include the following steps:
[0143] Step 501: Receive multiple SPS PDSCH resources.
[0144] Step 502: Among the N SPS PDSCH resources, NACK feedback corresponding to the non-skipped SPS PDSCH resources is performed and jointly reported.
[0145] In the embodiment of the present disclosure, after the UE receives multiple SPS PDSCH resources, among the N SPS PDSCH resources, there may be non-skipped SPS PDSCH resources and skipped SPS PDSCH resources.
[0146] In one possible case, joint reporting is performed for non-skipped SPS PDSCH resource corresponding non-acknowledgement NACK feedback.
[0147] Step 503: Among the N SPS PDSCH resources, the NACK feedback corresponding to the skipped SPS PDSCH resource and the ACK feedback corresponding to the non-skipped SPS PDSCH resource are not reported.
[0148] In another possible case, NACK feedback corresponding to skipped SPS PDSCH resources and ACK feedback corresponding to non-skipped SPS PDSCH are not reported, thereby reducing SPS PDSCH HARQ-ACK feedback overhead.
[0149] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0150] The present disclosure provides another HARQ transmission method. Figure 6 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0151] like Figure 6 As shown, the HARQ transmission method may include the following steps:
[0152] Step 601: Receive multiple SPS PDSCH resources.
[0153] Step 602: jointly report the feedback of N SPS PDSCH resources in the form of a bitmap.
[0154] In the disclosed embodiment, after receiving multiple SPS PDSCH resources, the UE divides the multiple SPS PDSCH resources into N groups, and can jointly report feedback of the N SPS PDSCH resources in a bitmap format in each group.
[0155] In the disclosed embodiment, among N SPS PDSCH resources, each SPS PDSCH corresponds to a bit in the bitmap, wherein the position corresponding to the NACK feedback in the non-skipped SPS PDSCH corresponds to the first flag, and the other positions correspond to the second flag, wherein the first flag and the second flag are different.
[0156] As an example, assuming that each SPS PDSCH corresponds to 1 bit, N SPS PDSCH resources require N bits, and the position corresponding to NACK in the non-skipped SPS PDSCH is marked with 1, and the remaining positions are filled with 0. Alternatively, the position corresponding to NACK in the non-skipped SPS PDSCH is marked with 0, and the remaining positions are filled with 1, which is not limited here.
[0157] It should be explained that, since N is fixed, the feedback overhead will not change with the change of the number of SPS PDSCH transmission opportunities within the N window.
[0158] As a possible implementation manner, the UE may obtain the actual number of transmissions M of the non-skipped SPS PDSCH among N SPS PDSCH resources, and generate a bitmap having M bits.
[0159] Among the M-bit bitmap, the position at the non-skipped SPS PDSCH and corresponding to the NACK feedback corresponds to the first flag, and the other positions of the bitmap correspond to the second flag.
[0160] As a possible implementation method of an embodiment of the present disclosure, when determining the actual number of transmissions M, the transmission power of each non-skipped SPS PDSCH among N SPS PDSCH resources can be obtained. In response to the transmission power of each non-skipped SPS PDSCH being greater than a preset threshold, it is determined that an actual transmission has been performed.
[0161] It can be understood that during the actual transmission of the non-skipped SPS PDSCH, the transmission power will change, the power of the actual transmitted data is higher, and the power of the non-transmitted data is lower. Therefore, it is possible to determine whether the SPS PDSCH resource has actually been transmitted based on the transmission power of each non-skipped SPS PDSCH among the N SPS PDSCH resources.
[0162] As another possible implementation method of the embodiment of the present disclosure, when determining the actual number of transmissions M, the DMRS (Demodulation Reference Signal) of each non-skipped SPS PDSCH among the N SPS PDSCH resources can also be obtained, and then the actual number of transmissions M can be obtained based on the DMRS of each non-skipped SPS PDSCH.
[0163] It can be understood that during the actual transmission of the non-skipped SPS PDSCH, the DMRS signal can be detected. Therefore, whether the SPS PDSCH resource has been actually transmitted can be determined based on whether the DMRS signal can be detected.
[0164] As another possible implementation of the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the network side device through a display indication.
[0165] For example, the network side device can directly indicate the M value dynamically through the DCI, once every N units.
[0166] As another possible implementation manner of the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the network side device through implicit indication.
[0167] In the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the value of the feedback timing parameter K1 corresponding to the SPS PDSCH actually transmitted.
[0168] In the HARQ transmission method of the embodiment of the present disclosure, the UE receives multiple SPS PDSCH resources and jointly reports the feedback of N SPS PDSCH resources in the form of a bitmap, thereby reducing the SPS PDSCH HARQ-ACK feedback overhead.
[0169] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0170] The present disclosure provides another HARQ transmission method. Figure 7 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0171] like Figure 7 As shown, the HARQ transmission method may include the following steps:
[0172] Step 701: Receive multiple SPS PDSCH resources.
[0173] Step 702: In response to a NACK feedback of a non-skipped SPS PDSCH among N SPS PDSCH resources, a position index of the NACK feedback is reported.
[0174] In the disclosed embodiment, the UE obtains multiple SPS PDSCH resources, groups the multiple SPS PDSCH resources with N as the granularity, and if only one non-skipped SPS PDSCH NACK feedback occurs in each group, the NACK feedback position index is reported.
[0175] Step 703: In response to NACK feedbacks of multiple non-skipped SPS PDSCHs among the N SPS PDSCH resources, report according to a preset format.
[0176] In the disclosed embodiment, the UE obtains multiple SPS PDSCH resources, groups the multiple SPS PDSCH resources with N as the granularity, and if there are multiple non-skipped SPS PDSCH NACK feedbacks among the N SPS PDSCH resources in one group, they can be reported in a preset format.
[0177] For example, all 0s or all 1s may be fed back.
[0178] It should be explained that the above steps 702 and 703 are not executed sequentially, but the execution of step 702 or step 703 is determined according to the number of NACK feedbacks of non-skipped SPS PDSCH among the N SPS PDSCH resources.
[0179] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0180] The present disclosure provides another HARQ transmission method. Figure 8 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a UE. The HARQ transmission method can be executed alone, or in combination with any embodiment of the present disclosure or a possible implementation method in an embodiment, or in combination with any technical solution in the related art.
[0181] like Figure 8 As shown, the HARQ transmission method may include the following steps:
[0182] Step 801: Receive multiple SPS PDSCH resources.
[0183] Step 802: Obtain the actual number of transmissions M of the non-skipped SPS PDSCH among the N SPS PDSCH resources.
[0184] As a possible implementation method of an embodiment of the present disclosure, when determining the actual number of transmissions M, the transmission power of each non-skipped SPS PDSCH among N SPS PDSCH resources can be obtained. In response to the transmission power of each non-skipped SPS PDSCH being greater than a preset threshold, it is determined that an actual transmission has been performed.
[0185] It can be understood that during the actual transmission of the non-skipped SPS PDSCH, the transmission power will change, the power of the actual transmitted data is higher, and the power of the non-transmitted data is lower. Therefore, it is possible to determine whether the SPS PDSCH resource has actually been transmitted based on the transmission power of each non-skipped SPS PDSCH among the N SPS PDSCH resources.
[0186] As another possible implementation method of the embodiment of the present disclosure, when determining the actual number of transmissions M, the DMRS (Demodulation Reference Signal) of each non-skipped SPS PDSCH among the N SPS PDSCH resources can also be obtained, and then the actual number of transmissions M can be obtained based on the DMRS of each non-skipped SPS PDSCH.
[0187] It can be understood that during the actual transmission of the non-skipped SPS PDSCH, the DMRS signal can be detected. Therefore, whether the SPS PDSCH resource has been actually transmitted can be determined based on whether the DMRS signal can be detected.
[0188] As another possible implementation of the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the network side device through a display indication.
[0189] For example, the network side device can directly indicate the M value dynamically through the DCI, once every N units.
[0190] As another possible implementation manner of the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the network side device through implicit indication.
[0191] In the embodiment of the present disclosure, the actual number of transmissions M may also be determined by the value of the feedback timing parameter K1 corresponding to the SPS PDSCH actually transmitted.
[0192] Step 803: In response to a NACK feedback being received during the M actual transmissions of the non-skipped SPS PDSCH, a position index of the NACK feedback is reported.
[0193] In the disclosed embodiment, when determining the actual transmission of M non-skipped SPS PDSCHs sent in each group, if there is only one NACK feedback, the position index of the NACK feedback is reported.
[0194] Step 804: In response to multiple NACK feedbacks during the actual transmission of M non-skipped SPS PDSCHs, reporting is performed according to a preset format.
[0195] In the embodiment of the present disclosure, when determining the actual transmission of M non-skipped SPS PDSCHs sent in each group, if there are multiple NACK feedbacks, they are reported according to a preset format. For example, all 0s or all 1s may be fed back.
[0196] In the HARQ transmission method of the disclosed embodiment, after receiving multiple SPS PDSCH resources, the UE obtains the actual number of transmissions M of non-skipped SPS PDSCH among the N SPS PDSCH resources, and in response to one NACK feedback among the actual transmissions of the M non-skipped SPS PDSCHs, reports the position index of the NACK feedback, and in response to multiple NACK feedbacks among the actual transmissions of the M non-skipped SPS PDSCHs, reports according to a preset format. Thus, the SPS PDSCH HARQ-ACK feedback overhead is reduced.
[0197] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.
[0198] In order to implement the above embodiment, the present disclosure also proposes another HARQ transmission method: Fig. 9 A flow chart of another HARQ transmission method provided in an embodiment of the present disclosure. The HARQ transmission method can be applied to a network side device. The HARQ transmission method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related technology.
[0199] like Fig. 9 As shown, the HARQ transmission method may include the following steps:
[0200] Step 901: Send multiple SPS PDSCH resources to a UE.
[0201] In the disclosed embodiment, the network side device may send multiple SPS PDSCH resources to the UE.
[0202] In one possible case, when the network side device sends multiple SPS PDSCH resources to the UE, the N SPS PDSCH resources can be grouped and bundled.
[0203] Wherein, N is specified by the protocol and is one or more candidate values.
[0204] In the embodiment of the present disclosure, the network side device may determine N by displaying an indication. Specifically, the network side device may send a candidate value set to the UE, wherein the candidate value set includes multiple candidate values. Further, the network side device sends a first configuration signaling to the UE, so that after the UE receives the first configuration information, it determines N from the multiple candidate values according to the first configuration information. The first configuration signaling is used to select N from the multiple candidate values.
[0205] In the embodiments of the present disclosure, the indication granularity of N is various.
[0206] The first configuration instruction is used to indicate one or more UEs, wherein the one or more UEs include at least one of the following: a single SPS PDSCH configuration of a single UE; a single UE; multiple UEs in a group; multiple UEs in a cell.
[0207] In the embodiment of the present disclosure, N may also be determined by implicit indication.
[0208] Step 902: Acquire feedback information jointly reported with a granularity of N among multiple SPS PDSCH resources, where N is a positive integer greater than 1.
[0209] In the HARQ transmission method of the disclosed embodiment, after the network side device sends multiple SPS PDSCH resources to the UE, it obtains the feedback information jointly reported in the multiple SPS PDSCH resources with a granularity of N. Thus, the UE reduces the SPS PDSCH HARQ-ACK feedback overhead by bundling the SPS PDSCH resources.
[0210] It should be noted that the above Figures 1 to 8 The explanation of the HARQ transmission method performed by the UE in any embodiment is also applicable to the HARQ transmission method performed by the network side device in this embodiment.
