In next generation communication system, for example, in NR systems, UE can have one or more kinds of bandwidth abilities, i.e. UE Bandwidth ability can be less than system bandwidth.For example, UE can support the first bandwidth and the second bandwidth, wherein the first bandwidth Less than the second bandwidth.It receives and sends messages relative in the first bandwidth, UE in the second bandwidth when receiving and sending messages, number to be treated According to amount bigger, and then lead to energy consumption bigger, therefore, is in energy saving consideration, UE expectations can at least receive in the first bandwidth Control channel.In a kind of possible scene, in a time domain thread, UE can use the first bandwidth to receive control letter Road receives data channel using the second bandwidth.In alternatively possible scene, when UE can use the first bandwidth to receive first The first control channel in domain scheduling unit and the first data channel are received using the second bandwidth in the second time domain thread Second control channel and the second data channel.Due to of different sizes and/or the first bandwidth and of the first bandwidth and the second bandwidth The center frequency point of two bandwidth is different, and when UE is switched to the second bandwidth from the first bandwidth, there are a handover delay, the switchings Time delay can be carrier level, can also be UE specific.

Below by UE for the second bandwidth is switched to the first bandwidth, several the case where may causing handover delay, are carried out It illustrates.

The first bandwidth and the second bandwidth it is of different sizes in the case of, UE has two sets of radio-frequency units, is expressed as First radio-frequency unit and the second radio-frequency unit.Wherein, which is used to receive and send messages under the first bandwidth, and second Radio-frequency unit under the second bandwidth for receiving and sending messages.When UE uses the second bandwidth transceiving data, UE is filled using the second radio frequency It sets and data is handled, when UE is switched to the first bandwidth from the second bandwidth, UE needs to start the first radio-frequency unit to data It is handled.Since the startup of the first radio-frequency unit needs certain time, certain handover delay, such as about 20 are may result in μ s or so.

The first bandwidth and the second bandwidth it is of different sizes in the case of, UE only has a set of radio-frequency unit, for data It is handled, when UE is switched to the first bandwidth by the second bandwidth, needs to be adjusted the device in radio-frequency unit, above-mentioned tune It is whole to relate to, but are not limited to adjustment analog-digital converter (English：Analog to Digital Coverter, ADC) before anti-aliasing filter Channel digital filter after wave device and ADC adjusts ADC sample rates, correcting power amplifier etc..Above-mentioned adjustment may Lead to longer handover delay, such as about 40 μ s or so.

In the case of the center frequency point difference of the first bandwidth and the second bandwidth, if the first bandwidth and the second bandwidth are located at In the same frequency range, when UE is switched to the first bandwidth from the second bandwidth, UE may need voltage controlled oscillator to be adjusted, because In bandwidth handoff procedure, voltage controlled oscillator needs to adjust angular frequency, and then needs to adjust voltage, and handover delay may reach 100-200μs.If the first bandwidth and the second bandwidth are located at different frequency bands, when UE is switched to the first bandwidth from the second bandwidth When, UE may also need to calibrate power amplifier other than being adjusted voltage controlled oscillator.Above-mentioned adjustment is led The time delay of cause, for instance it can be possible that about 300 μ s, 600 μ s, 900 μ s etc..Further, when control channel bandwidth and data channel Bandwidth it is of different sizes when, it is also possible to be related to for ADC sample rates, above-mentioned frequency overlapped-resistable filter and channel digital filter etc. The adjustment of device, above-mentioned adjustment can equally bring handover delay.

In view of this, the embodiment of the present application provides a kind of communication means, for being configured according to the different bandwidth abilities of UE The UE control channels bandwidth and data channel bandwidth, wherein the first running time-frequency resource of the control information for carrying the UE exists Within the control channel bandwidth, for carry the UE data information the second running time-frequency resource in the data channel bandwidth Within, data are dispatched according to first running time-frequency resource and second running time-frequency resource.In this application, the first time-frequency money Source can take the control channel bandwidth on frequency domain, and one in the control channel bandwidth can also be occupied on frequency domain Divide bandwidth；Second running time-frequency resource can take the data channel bandwidth on frequency domain, and institute can also be occupied on frequency domain State a part of bandwidth in control channel bandwidth.The network equipment according to the relationship of the control channel bandwidth and the first bandwidth and The relationship of the data channel bandwidth and the first bandwidth, to determine the starting time-domain position of second running time-frequency resource, to have Effect ensure that under the scene that UE switches between different bandwidth, remain able to the accuracy that transceiving data is effectively ensured.

It should be noted that the first bandwidth being previously mentioned in embodiment in this application is less than the second bandwidth, the control of UE Channel width and data channel bandwidth are respectively less than or are equal to second bandwidth.Second bandwidth can be that UE theoretically can The maximum bandwidth enough supported can be the maximum bandwidth that UE can actually be supported, can also be that UE is currently able to the maximum supported Bandwidth.In the demand for reducing energy consumption, UE wishes to receive the control information in first bandwidth.In the concrete realization, The network equipment is indicated before the inscribed receipts control information of first bandwidth in UE, alternatively, asking the net in UE Network equipment by the control channel band width configuration within first bandwidth before, UE can be received in second bandwidth The control information and downlink data.It is a kind of possible after the network equipment receives the instruction or request of UE transmissions Situation, the network equipment can configure the control channel bandwidth according to the instruction of the UE in first bandwidth.Another kind can The case where energy, the network equipment can be to configure the control in first bandwidth to determine according to the service condition of Current resource Channel width processed still configures the control channel bandwidth in the second bandwidth.

The embodiment of application is described in detail below in conjunction with the accompanying drawings, so as to those skilled in the art understand that.

Fig. 2 is a kind of flow diagram of the communication means 200 provided according to one embodiment of the application.This method 200 can be applied in scene shown in FIG. 1.Method 200 includes the following steps.

S201, the network equipment determine the first running time-frequency resource and the second running time-frequency resource.

Specifically, the network equipment determines described in first running time-frequency resource and the carrying of the control information of carrying terminal device Second running time-frequency resource of the data information of terminal device.Wherein, control of first running time-frequency resource in the terminal device Within channel width processed, all or part of control channel bandwidth can be occupied on frequency domain.The second time-frequency money Source can occupy all or part of data channel within the data channel bandwidth of the terminal device on frequency domain It is wide.First running time-frequency resource be for terminal device send control information running time-frequency resource, the second running time-frequency resource be for To the running time-frequency resource of terminal device transmission data information.It is understood that when control channel resource is there are when idling-resource, It can be used for the terminal device transmission data information.The center of the control channel bandwidth and data channel bandwidth frequency Point may be the same or different.

Below according to control channel bandwidth, the relationship of data channel bandwidth and the first bandwidth, to be specifically described different situations Under, the various possible modes of the time-domain position for configuring the first running time-frequency resource and the second running time-frequency resource, including but not limited to It is several below.

In first specific embodiment, if the control channel bandwidth is less than or equal to first bandwidth, And the data channel is wider than first bandwidth, first running time-frequency resource and second running time-frequency resource are in the time domain It is spaced M1 symbol, M1 >=1.In other words, the last one time-domain symbol of first running time-frequency resource is provided with second time-frequency First time-domain symbol in source is spaced M1 symbol, M1 >=1 in the time domain.Specifically, the network equipment is in first bandwidth The interior configuration control channel bandwidth, configures the data channel bandwidth, i.e., terminal device is first in second bandwidth Control information is received in bandwidth, and data information is received in the second bandwidth.Therefore, UE is needed when receiving data information from One bandwidth is switched to the second bandwidth, can lead to handover delay, in the application, configures the first running time-frequency resource and the second running time-frequency resource exists It is at least spaced a time-domain symbol in time domain, Data reception errors caused by handover delay institute possibility can be effectively reduced, improved The accuracy of transceiving data.For example, 2 symbols of the control channel resource occupation of network equipments configuration, the first running time-frequency resource On first symbol, the network equipment sends instruction information to terminal device, and instruction terminal equipment detects on first symbol Control information.At this point, in order to reduce Data reception errors, the first running time-frequency resource and the second time-frequency caused by handover delay institute possibility At least one symbol is spaced between resource.Assuming that being spaced a symbol between the first running time-frequency resource and the second running time-frequency resource, you can To ensure the accuracy of data receiver, then the primary sign of the second running time-frequency resource can be the 3rd symbol.That is the first running time-frequency resource And second be spaced 1 symbol between running time-frequency resource, and space character is not necessarily between control channel and data channel.

The value of the M1 can be that cell is specific, can also be UE specific.It is specific in cell, to cell For interior all UE, the value of M1 can be identical, and the value of the M1 can be determined by the network equipment.In the specific situations of UE Under, it is constrained by UE device performances, for different UE, the handoff delay when bandwidth switches is also different, therefore, for not Different values may be used in same UE, M1.In the case of UE is specific, it is in first time-frequency that M1 >=N, N, which are more than or equal to 1, N, Under resource or the corresponding systematic parameter of second running time-frequency resource, first running time-frequency resource that the terminal device can be supported The minimum symbolic number being spaced in the time domain with second running time-frequency resource.Before the systematic parameter includes subcarrier spacing and recycles Sew (English：Cyclic Prefix, CP) length.For different UE, due to the difference of self performance, it is reported to network The N of equipment may be different.For example, for the first UE, N is, for example, 2, and for the 2nd UE, N is, for example, 3.This Application is not specifically limited the value of N, and UE is determined according to self performance.Therefore, the finger that the network equipment can be reported according to UE Show information specifically to determine the value of M1.Be specifically described below and how to determine M1, determine M1 mode include but not limited to Lower two ways.

Mode one, the terminal device send the first instruction information to the network equipment, and the first instruction information is used In instruction N.The first instruction information can be an absolute time length, such as 20 μ s.At this point, the network equipment or terminal are set For according to first running time-frequency resource or the corresponding systematic parameter of second running time-frequency resource, the absolute time length is calculated in institute State corresponding symbol numbers under systematic parameter.For example, in the subcarrier spacing of 30KHz, under conventional CP, 20 μ s may correspond to one Symbol.The first instruction information can also be the symbol numbers under predefined frame of reference parameter.Such as in 60KHz subcarriers It is 2 symbols under interval, routine CP.At this point, the network equipment or terminal device are according to the predefined frame of reference parameter, described First running time-frequency resource or the corresponding systematic parameter of second running time-frequency resource, it is right under the systematic parameter to calculate the symbol numbers The symbol numbers answered.For example, at 30KHz subcarrier spacings, routine CP, corresponding 1 symbol.The first instruction information may be used also Directly to indicate the value of the N, for example, UE determines the value of N according to self performance, the value of the N is directly reported to the network equipment. The application is not specifically limited the concrete form of the first instruction information.

After the network equipment receives the first instruction information, according to N to determine M1, and sent to the terminal device Second instruction information, is used to indicate M1.Wherein, the first instruction information can be carried on random access guiding (English： Preamble in), or it is carried on message 3 (Msg.3), or be carried in high-level signaling, such as wireless heterogeneous networks (English： Radio Resource Control, RRC) signaling or media access control (English：Media Access Control, MAC) Layer signaling, can also be carried in dedicated signaling, the application is not especially limited this.In addition, the second instruction information It can either system message or dedicated signaling bear, the application be not especially limited this by high-level signaling.

Mode two, the terminal device determines N according to the performance of itself, and determines M1 according to N, and the M1 of the determination is more than etc. In N.Terminal device sends third to the network equipment and indicates that information, third instruction information are used to indicate M1.The network equipment receives institute After stating third instruction information, determines M1, the time-domain position of first running time-frequency resource and the second running time-frequency resource is configured according to M1. Third instruction information can be carried in random access preamble, or be carried on message 3 (Msg.3), or be carried on high level In signaling, such as RRC signaling or MAC layer signaling, it can also be carried in dedicated signaling, the application does not limit this specifically It is fixed.

It is appreciated that being directed to different UE, the value of M1 is different, has fully considered the difference of UE self performances, has further carried High UE receives the accuracy of data.

In second specific embodiment, if the control channel bandwidth and the data channel bandwidth are respectively less than Or it is equal to first bandwidth, first running time-frequency resource is spaced M2 symbol in the time domain with second running time-frequency resource, M2≥0.Similarly, in third specific embodiment, if the control channel bandwidth and the data channel bandwidth are equal When more than or equal to first bandwidth, first running time-frequency resource is spaced M3 in the time domain with second running time-frequency resource Symbol, M3 >=0, details are not described herein again.

In above-mentioned second or third specific embodiment, the primary sign of second running time-frequency resource and described the 0 symbol or at least one symbol are spaced between the terminating symbol of one running time-frequency resource.Due to control channel bandwidth and data channel Bandwidth all in first bandwidth or all in second bandwidth, cut when receiving data information without bandwidth by terminal device It changes, handover delay is not present, therefore, first running time-frequency resource is not necessarily to be spaced time domain with second running time-frequency resource in the time domain Symbol.Certainly, the network equipment is based on real resource dispatch situation, can also configure the first running time-frequency resource and the second running time-frequency resource it Between be spaced one or more time-domain symbols, said program improves the flexibility of resource distribution.

It is understood that in second or third embodiment, data channel can be allowed to be multiplexed the first bandwidth or the The idle frequency domain resource of symbol in two bandwidth where control channel carrys out transmission data information.For example, first bandwidth For 5MHz, the control channel bandwidth is 4MHz, and control channel occupies symbol 0 and symbol 1, there is the frequency domain of 1MHz in the first bandwidth Resource is idle.Therefore, data channel can be multiplexed on symbol 0 and symbol 1 the above-mentioned free time frequency domain resource come transmission data letter Breath, i.e. the starting time-domain symbol of the second running time-frequency resource can be aligned with the starting time-domain symbol of first running time-frequency resource, or Say between the starting time-domain symbol of the second running time-frequency resource and the starting time-domain symbol of first running time-frequency resource be spaced 0 symbol or At least one symbol.Not used bandwidth resources in data channel statistical multiplex control channel as a result, improve resource utilization And the flexibility that resource uses.

In the 4th specific embodiment, if the control channel band is wider than first bandwidth, the number It is believed that road is less than or equal to first bandwidth, then first running time-frequency resource is spaced in the time domain with second running time-frequency resource M4 symbol, M4 >=1.In this embodiment, similar with first embodiment, UE needs to switch when receiving data letter Bandwidth leads to handover delay, and a time domain is at least spaced in the time domain by configuring the first running time-frequency resource and the second running time-frequency resource Symbol can effectively reduce Data reception errors caused by handover delay institute possibility, improve the accuracy of transceiving data.
