Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be determined by one skilled in the art based on the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the present invention, the base station may be an evolved Node B (eNB). A base station may provide communication coverage for UEs in a particular geographic area. The base stations may be macro base stations and small base stations according to the size of communication coverage, and the small base stations may include micro base stations, pico base stations, home base stations, and the like.

In an embodiment of the invention, the UE is located in a specific geographical area of communication coverage provided by the base station. The UE may be static or mobile. The UE may be referred to as a Terminal (Terminal), a Mobile Station (MS), a Subscriber Unit (Subscriber Unit), a Station (Station), etc. The UE may be a Cellular Phone (Cellular Phone), a Personal Digital Assistant (PDA), a radio Modem (Modem), a Wireless communication device, a Handheld device (Handheld), a Laptop computer (Laptop computer), a Cordless Phone (core Phone), a Wireless Local Loop (WLL) station, or the like.

Each embodiment of the present invention is applicable to a Long Term Evolution (LTE) system. In order to make those skilled in the art better understand the technical solution of the present invention, fig. 1 shows a frame structure diagram of transmission time interval bundling in an LTE system.

When a UE transmits uplink data to a base station serving the UE on a certain frequency and a certain subframe allocated to the UE by the base station, the base station may not receive or correctly decode the uplink data (e.g., voice data) transmitted by the UE due to low uplink coverage strength. The TTI Bundling technique is to encode uplink data carrying the same information to form a plurality of uplink data (still carrying the same information) in different encoding forms, and transmit the uplink data in a plurality of consecutive uplink subframes, where the consecutive subframes form a transmission time interval bundle, and as shown in fig. 1, TTI bundle 1 (formed by subframes 0 to 3) and TTI bundle 2 (formed by subframes 6 to 9) are both formed by 4 consecutive uplink subframes, and TTI bundle 1 and TTI bundle 2 have the same frequency domain position. In an LTE system, one TTI corresponds to one subframe. The number of TTIs included in one TTI BUNDLE may be determined by the TTI _ BUNDLE _ SIZE, which may be configured by the base station for the UE. When the number of the continuous uplink subframes is more than or equal to 2 (the minimum value for deducing the configuration of TTI _ BUNDLE _ SIZE is 2), the transmission time interval binding can be realized. In the current LTE system, the base station sets the SIZE of TTI _ SIZE to 4, but other values are not excluded. When transmission of one TTI bundle is completed, the base station feeds back ACK (correct reception)/NACK (incorrect reception) once for the TTI bundle without feeding back ACK/NACK for every TTI in the TTI bundle. When the transmission of one TTI Bundle is not correctly received by the base station, the UE may retransmit the uplink data using bundling at the next TTI Bundle. For the initial transmission and at least one retransmission of the uplink data carrying the same information, the same hybrid automatic repeat request (HARQ) process is used to process the initial transmission and the at least one retransmission. However, even if the tti bundling technique is adopted, the base station still needs the UE to perform multiple retransmissions for tti bundling due to poor uplink coverage quality, which undoubtedly or causes an increase in the time delay for processing uplink data. According to the frequency diversity gain obtained by the frequency hopping technology, the accuracy of the base station for obtaining the uplink data can be improved, so that the retransmission times of the UE are reduced, and the time delay of the uplink data is reduced. Therefore, how to determine the frequency resource location of the tti bundling is a technical problem discussed in various embodiments of the present invention.

An aspect of an embodiment of the present invention provides a method for determining frequency resources, such as a schematic flow chart of the method for determining frequency resources shown in fig. 2A, where the method is used for a UE or a base station serving the UE, and the method includes the following steps.

A frequency hopping pattern including a plurality of transmission time interval bindings of the sub-frame is determined as Inter-bundle hopping (Inter-bundle hopping).

In 201, the base station may determine a frequency hopping pattern configured for the UE to be inter-tti hopping. The frequency hopping mode may be randomly selected by the base station for the UE, or the frequency hopping mode may be selected by the base station according to channel state information reported by the UE, or may be selected according to the number of times of cell switching of the UE. For example, if the channel state information indicates that the channel quality between the UE and the base station is greater than a predetermined threshold, inter-tti hopping is selected. And if the switching times of the UE cell is less than a certain threshold, selecting transmission time interval inter-binding frequency hopping.

The base station may send an RRC signaling to the UE through a Radio Resource Control (RRC) connection established between the UE and the base station, where the RRC signaling carries mode indication information for indicating that the frequency hopping mode is frequency hopping between transmission time interval bindings. For example, after the UE initially accesses the base station through a random access procedure, the base station may send the mode indication information through an RRC signaling when the UE fails a radio link to the base station and when the UE switches to the base station.

The base station may also send Downlink Control Information (DCI) to the UE through a physical downlink control channel, where the DCI carries mode indication information for indicating that the frequency hopping mode is frequency hopping between transmission time interval bindings.

The UE may determine the frequency hopping pattern to be inter-tti hopping according to the received pattern indication information.

202, in the frequency hopping mode, determining a frequency resource location where a transmission time interval including a plurality of subframes is bound, where the frequency resource location where the transmission time interval is bound includes the frequency resource locations of the plurality of subframes, where the frequency resource locations of the plurality of subframes are equal to the frequency resource location of a subframe k, the frequency resource location of the subframe k is determined by a frequency hopping variable of the subframe k, the frequency hopping variable of the subframe k is determined by a time domain location of the subframe k, and the subframe k is one of the plurality of subframes.

The base station or the UE determines that the frequency hopping mode is frequency hopping between transmission time interval bindings, and then the base station or the UE can know that frequency hopping exists between the transmission time interval bindings, the frequency resource positions of all subframes in one transmission time interval binding are the same, and the frequency hopping is not performed between the subframes in one transmission time interval binding. Thus, the frequency resource location of one tti bundle is determined by the frequency resource location of one subframe (for ease of reference, subframe k is not assumed here) within the tti bundle. The frequency resource location bound by the transmission time interval can be determined according to the frequency hopping variable of the subframe k, and the frequency hopping variable of the subframe k is related to the time domain location of the subframe k.

As an example, the frequency hopping variable of the subframe k may be determined only by the time domain position of the subframe k, and the specific formula is as follows:

As another example, the frequency hopping variable of the subframe k may be determined by the time domain position of the subframe k and the current transmission number of uplink data to be sent by the UE, and the specific formula is as follows:

wherein i is the frequency hopping variable of the subframe k, n_sThe CURRENT _ TX _ NB is the CURRENT transmission number of the uplink data, which is the slot number of a slot included in the subframe k.

It should be noted that a subframe includes 2 slots, and the slot number of the subframe k takes two consecutive values from 0 to 19. The frequency hopping variable of the subframe k calculated by using the slot number of any one slot included in the subframe k according to the above formula is unique. The CURRENT transmission number CURRENT _ TX _ NB of the uplink data is the number of times the uplink data is retransmitted by the UE. And if the uplink data is transmitted by the UE for the first time, the CURRENT transmission time CURRENT _ TX _ NB of the uplink data is 0.

As another example, the frequency hopping variable of the subframe k may be determined by the system frame number of the radio frame in which the subframe k is located and the size of the tti binding, and the specific formula is as follows:

wherein i is the frequency hopping variable of the subframe k, SFN_kThe system frame number n of the wireless frame where the subframe k is located_sAnd the number of one time slot contained in the sub-frame K of the sub-band m, TTI _ BUNDLING _ SIZE is the bound SIZE of the transmission time interval, and K is a fixed constant.

For example, K is 10 or 20.

According to the value of the system frame number in the existing LTE system from 0 to 1023 and the value of the frequency hopping variable i from 0 to 9 or 0 to 19, the value of the frequency hopping variable is limited in the range by K, so that the calculation of the frequency hopping variable i in the existing LTE system can be compatible.

Calculating a frequency hopping variable of the subframe k, and determining the frequency resource position of the subframe k according to the frequency hopping variable of the subframe k, wherein a specific formula is as follows:

wherein,

wherein n is_PRBIs the frequency resource location, N, of the subframe k_sbFor the number of sub-bands used for physical uplink shared channel transmission, for the number of physical resource blocks comprised by said sub-bands, n_VRBA sub-indicated for the base stationThe position of the virtual resource block occupied by the frame k is the number of the physical resource blocks occupied by the physical uplink control channel, i is the frequency hopping variable of the subframe k, f_hop(i) Is the sub-band offset, f, corresponding to the sub-frame k_m(i) And the mirror image value is the mirror image value corresponding to the subframe k.

In step 202, the base station and the UE may obtain a frequency resource location of the tti bundle under frequency hopping within the tti bundle. The UE may retransmit uplink data to the base station through a physical uplink shared channel at the frequency resource location bound by the transmission interval, and the base station receives the uplink data retransmitted by the UE through the physical uplink shared channel at the frequency resource location bound by the transmission interval.

According to the method shown in fig. 2A, the frequency resource location diagrams shown in fig. 2B and fig. 2C can be obtained. As shown in fig. 2B and fig. 2C, in the case of inter-tti hopping, all subframes in the same tti do not hop, hopping between adjacent ttis is performed, the frequency resource location of each tti is determined by the method shown in fig. 2A, and the time domain location of each tti can be indicated by the base station through RRC signaling or DCI (the base station can indicate at least one tti of each tti), so as to obtain the physical resource location of each tti.

In the embodiment of the present invention, when the frequency hopping mode is inter-tti hopping, a tti binding includes a plurality of subframes occupying the same frequency resource location, so that the frequency resource location of the tti binding is equal to the frequency resource location of subframe k in the plurality of subframes, and the frequency resource location of the tti binding can be obtained according to the hopping variable of the subframe k. By applying the technical scheme provided by the embodiment of the invention, the frequency hopping among all subframes in the same transmission time interval binding and the frequency hopping among different transmission time interval bindings can be realized, so that the TTI bundling technology and the frequency hopping technology are correctly combined together, the transmission quality of uplink data can be improved, and the experience of user equipment is improved.

Another aspect of the embodiments of the present invention provides a method for determining frequency resources, such as the schematic flow chart of the method for determining frequency resources shown in fig. 3, where the method is used for a user equipment or a base station serving the user equipment, and the method includes the following steps.

301, determining a frequency hopping mode of transmission time interval bundling as Intra-Inter-bundle (Intra and Inter-bundle) frequency hopping of transmission time interval bundling, where the transmission time interval bundling includes N subbands.

In 301, the base station may determine a frequency hopping pattern configured for the UE to be intra-inter-bundle transmission time interval hopping. The frequency hopping mode may be randomly selected by the base station for the UE, or the frequency hopping mode may be selected by the base station according to channel state information reported by the UE, or may be selected according to the number of times of cell switching of the UE. For example, if the channel state information indicates that the channel quality between the UE and the base station is less than a predetermined threshold, inter-tti hopping is selected. And if the switching times of the UE cell is more than a certain threshold, selecting transmission time interval inter-binding frequency hopping.

The base station can send RRC signaling to the UE through the radio resource control RRC connection established between the UE and the base station, wherein the RRC signaling carries mode indication information for indicating that the frequency hopping mode is a mode between transmission time interval binding and inter-binding. For example, after the UE has initially accessed the base station through a random access procedure, when a radio link failure occurs to the base station or when the UE is handed over to the base station, the base station may send the mode indication information through an RRC signaling.

The base station may also send DCI to the UE through a physical downlink control channel, where the DCI carries mode indication information for indicating that the frequency hopping mode is intra-inter-bonding for transmission time interval. For example, when the UE initially accesses the base station through a random access procedure, the base station carries the mode indication information in the DCI transmitted in response to the UE.

The UE may determine the frequency hopping mode as intra-inter-bonding frequency hopping within a transmission time interval according to the received mode indication information.

302, in the frequency hopping mode, determining a frequency resource location of a subband m in the N subbands, where the frequency resource locations of all subframes in the subband m are the same, the frequency resource location of the subband m is equal to the frequency resource location of a subframe k in the subband m, the subband m is one subband in the N subbands, and the subframe k in the subband m is one subframe in the subband m.

The base station or the UE determines that the frequency hopping mode is intra-bundling inter-transmission time interval hopping, and then the base station or the UE can know that one transmission time interval bundling is composed of N subbands, and each of the first N-1 subbands is composed of Y subframes at a frequency hopping interval. Since the total number of all sub-frames in the tti bundling may not be evenly divisible by Y, the number of sub-frames constituting the last subband is the total number of sub-frames in a tti bundling minus Y (N-1). The frequency resource positions of all sub-frames in each sub-band are the same (that is, frequency hopping is not performed between sub-frames in one sub-band), and the frequency resource positions (which may be the same or different) of different sub-bands are calculated by the frequency resource position formula of different sub-bands, thereby realizing frequency hopping between sub-bands. The base station or the UE determines the frequency resource location of a sub-frame in a sub-band (e.g., the sub-frame k in the sub-band m), and then determines the frequency resource location of the sub-band.

It should be noted that the frequency hopping interval Y is configured by the base station, and the base station may carry the frequency hopping interval Y in RRC signaling or DCI and send the RRC signaling or DCI to the UE.

As an example, the frequency resource location of sub-frame k in sub-band m is determined by the frequency hopping variable of sub-frame k in sub-band m; the frequency hopping variable of the sub-frame k in the sub-band m is determined by the following formula:

or

Wherein i is the frequency hopping variable of the sub-frame k in the sub-band m, n_sA slot of one of the slots included in the sub-frame k of the sub-band mThe CURRENT _ TX _ NB is the CURRENT transmission number of uplink data; SFN_kThe system frame number of the wireless frame where the sub-frame k in the sub-band m is located is the system frame number; the Intra _ bundle _ size is the frequency hopping interval, and K is a fixed constant.

It should be noted that a subframe includes 2 slots, and the slot number of the subframe k takes two consecutive values from 0 to 19. The frequency hopping variable of the subframe k calculated by using the slot number of any one slot included in the subframe k according to the above formula is unique.

As an example, the frequency resource location of the subframe k is determined according to the frequency hopping variable of the subframe k, and a specific frequency resource location formula is as follows:

wherein,

As another example, unlike the above example, the frequency resource location of subband m may not be determined by the frequency resource location of subframe k in subband m. In this example, the N subbands in one tti bundle include odd and even subbands, and frequency resource locations of the odd and even subbands, thereby implementing intra-tti bundling. Optionally, the frequency resource locations of all even subbands in the multiple transmission time interval bindings are the same, and the frequency resource locations of all odd subbands are the same, in this case, the frequency resource locations of the even subbands and the odd subbands in one transmission time interval binding are determined, so that the frequency resource locations of the even subbands and the odd subbands in all transmission time interval bindings can be obtained.

Optionally, the frequency resource location of an odd subband is indicated by the base station

The frequency resource location of the even subbands is determined by the following formula:

optionally, the frequency resource location of even subband is indicated by the base station

The frequency resource location of the odd subband is determined by the following formula:

in the above formula, when m is odd number, the subband m is the frequency resource location and RB is the number of physical resource blocks occupied by the physical uplink control channel_STARTThe position of the physical resource block indicated for the base station is the number of physical resource blocks used for physical uplink shared channel transmission, and is the frequency resource position of the subband m when m is an even number.

In step 302, the base station and the UE may obtain a frequency resource location of the tti bundle under frequency hopping within the tti bundle. The UE may retransmit uplink data to the base station through a physical uplink shared channel at the frequency resource location bound by the transmission interval, and the base station receives the uplink data retransmitted by the UE through the physical uplink shared channel at the frequency resource location bound by the transmission interval.
