Description

Channel multiplexing method and equipment

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a channel multiplexing method and device.

Background

Currently, in a wireless communication system, three channels are mainly defined, which are a logical channel, a transport channel, and a physical channel. Wherein the logical channel is used to provide a data transfer service. The transport channels are used to define the manner and characteristics of data transmission in the air interface. The physical channel is used to define the bearer over which the signal is transmitted over the air interface. In practical applications, the service data of multiple logical channels are mapped onto the transport channel, and then transmitted through the physical channel.

In the prior art, the service data of a plurality of logical channels are generally mapped onto one transport channel, that is, several logical channels will multiplex one transport channel. Currently, the mapping procedure of the logical channel is as follows: firstly, judging whether a token accumulation variable Bj corresponding to each logic channel is greater than zero; if the token accumulation variable Bj of a certain logical channel is less than zero, the logical channel is not mapped to the transmission channel; if the token accumulation variable Bj of the logical channel is greater than zero, comparing the priority of the logical channel with Bj greater than zero, and preferentially mapping the logical channel with high priority to the transmission channel.

Next, how to set the size of each logical channel Bj is described: in the prior art, the terminal maintains a token accumulation variable Bj for each logical channel j, and the initial value of the token accumulation variable Bj is 0. And Bj of each logical channel will increase at a PBR × TTI rate, i.e. Bj will increase the PBR × TTI size in each TTI, for example, PBR of a logical channel is 8Bps, TTI is 1ms, then Bj will increase the size of 8 × 1 in each 1 ms. Where the TTI is a time interval for the terminal to transmit data, for example, the TTI is 1ms, the terminal will transmit data every 1ms, and the size of the logical token accumulation variable Bj will increase by PBR (for example, 8) every 1 ms. The PBR is a Prioritized Bit Rate (Prioritized Bit Rate), and the PBR is set according to an average transmission Rate of the logical channel, and the average transmission Rate of the logical channel is different, and the PBRs corresponding to the PBR are also different.

In the current wireless communication system, TTIs of all logical channels are the same, and are 1ms, and the 1ms exactly corresponds to 1 radio subframe. In the fifth generation mobile communication system, the related art proposes the concept of STTI, in which the TTI is set to less than 1ms, for example, 0.5 ms. In the STTI scenario, how to multiplex logical channels is not currently related to the solution.

Detailed Description

For ease of understanding, the illustrations of the concepts related to the present application are given for reference as follows:

a Base Station (BS) device, which may also be referred to as a base station, is a device deployed in a radio access network to provide wireless communication functions. For example, a device providing a base station function in a 2G network includes a Base Transceiver Station (BTS) and a Base Station Controller (BSC), a device providing a base station function in a 3G network includes a node B (english NodeB) and a Radio Network Controller (RNC), a device providing a base station function in a 4G network includes an evolved node B (evolved NodeB, eNB), and a device providing a base station function in a WLAN is an Access Point (AP). In a future 5G network, such as New Radio (NR) or LTE +, devices providing base station functionality include node b (gnb) for continued evolution, TRP (transmission and reception point), or TP (transmission point). The TRP or TP may not include a baseband part, only include a radio frequency part, or include a baseband part and a radio frequency part.

A User Equipment (UE) is a terminal device, which may be a mobile terminal device or an immobile terminal device. The device is mainly used for receiving or sending service data. The user equipments may be distributed in networks where the user equipments have different names, such as: a terminal, a mobile station, a subscriber unit, a station, a cellular telephone, a personal digital assistant, a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless telephone, a wireless local loop station, a vehicle mounted device, etc. The user equipment may communicate with one or more core networks via a Radio Access Network (RAN), an access portion of a wireless communication network, for example to exchange voice and/or data with the radio access network.

The network side device, which is a device located at a network side in a wireless communication network, may be an access network element, such as a base station or a controller (if any), or may also be a core network element, or may also be another network element.

Transmission Time Interval (TTI): the time unit for transmitting data for the terminal, for example, TTI may be 1 ms;

STTI (short Transmission Time Interval): the TTI is less than 1ms, for example, the TTI can be 0.5ms and 2 symbols, etc.

Logical channel: the MAC sublayer provides services to the upper layers indicating what the content of the bearer is. Logical channels can be generally classified into two categories: control channels and traffic channels. The control channel is used to transmit control plane information and the traffic channel is used to transmit user plane information. The Control Channel (CCH) is used for transmitting signaling or synchronization data, and the Traffic Channel (TCH) transmits encoded and encrypted speech or data.

Transmission channel: for defining the manner and characteristics of data transmission in the air interface.

Physical channel: for defining the bearer over which the signal is transmitted in the air interface.

The technical scheme of the application is described in the following with reference to the attached drawings:

the method and the device can be particularly applied to a scene of multiplexing the logic channel under an STTI scene.

Fig. 1 shows a schematic diagram of a possible system network of the present application. As shown in fig. 2, at least one terminal device UE10 communicates with a Radio Access Network (RAN). The RAN comprises at least one base station 20 (BS), of which only one base station and one UE are shown for clarity. The RAN is connected to a Core Network (CN). Optionally, the CN may be coupled to one or more external networks (external networks), such as the internet, Public Switched Telephone Network (PSTN), and the like.

It should be understood that the logical channel of the UE10 has the service data to be transmitted, and the plurality of logical channels are multiplexed to the transport channel, so that the service data can be transmitted to the base station 20 via the physical channel.

It should be noted that, generally, the service data of multiple logical channels will be mapped onto one transport channel, that is, several logical channels will multiplex one transport channel. Currently, the mapping procedure of the logical channel is as follows: firstly, judging whether a token accumulation variable Bj corresponding to each logic channel is greater than zero; if the token accumulation variable Bj of a certain logical channel is less than zero, the logical channel is not mapped to the transmission channel; if the token accumulation variable Bj of the logical channel is greater than zero, comparing the priority of the logical channel with Bj greater than zero, and preferentially mapping the logical channel with high priority to the transmission channel.

Next, how to set the size of each logical channel Bj is described: the terminal maintains a token accumulation variable Bj for each logical channel j, and the initial value of the token accumulation variable Bj is 0. And Bj of each logical channel will increase at a PBR × TTI rate, i.e. Bj will increase the PBR × TTI size in each TTI, for example, PBR of a logical channel is 8Bps, TTI is 1ms, then Bj will increase the size of 8 × 1 in each 1 ms. Where the TTI is a time interval for the terminal to transmit data, for example, the TTI is 1ms, the terminal will transmit data every 1ms, and the size of the logical token accumulation variable Bj will increase by PBR (for example, 8) every 1 ms. The PBR is a Prioritized Bit Rate (Prioritized Bit Rate), and the PBR is set according to the priority of the logical channel, and the priority of the logical channel is different, and the PBRs corresponding to the logical channel are also different.

Because the TTI of each logical channel is less than 1ms in the STTI scenario, how to maintain Bj of each logical channel and how to multiplex the logical channels at this time, currently, there is no solution.

Based on the above, a channel multiplexing method is provided, which is mainly used for how to determine the token accumulation variable Bj of each logical channel and how to perform logical channel multiplexing in an STTI scenario.

Some scenarios in the embodiment of the present application are described by taking a scenario of a 4G network in a wireless communication network as an example, it should be noted that the scheme in the embodiment of the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.

It should be noted that the method or apparatus in the embodiments of the present application may be applied between a wireless network device and a user equipment, may also be applied between a wireless network device and a wireless network device (such as a macro base station and a micro base station), and may also be applied between a user equipment and a user equipment (such as a D2D scenario).

Fig. 2 is a flow of a channel multiplexing method provided in an embodiment of the present application, and as shown in fig. 2, the method includes:

s21: the terminal device obtains a first configuration. .

S22: the terminal equipment acquires a first TTI parameter according to the first configuration;

in an example, the network device may determine a first configuration, send the first configuration to the terminal device, the first configuration including a first TTI parameter, and the terminal device receives the first configuration, in which the first TTI parameter is obtained.

More specifically, the first TTI parameter in the first configuration is used to configure a TTI of a logical channel of a terminal device, and the following example manner may be adopted:

in an example manner, the network device may configure { DL, UL } for each logical channel, where DL refers to the downlink TTI length allowed to be used by the logical channel, such as the number of symbols, and UL refers to the uplink TTI length allowed to be used by the logical channel, such as the number of symbols.

The { DL, UL } may be transmitted in an index manner, for example, as shown in table 1, 0 represents {2, 2}, which indicates that the DL TTI length allowed to be used by the logical channel is 2 symbols, the UL TTI length is 2 symbols, 1 represents {2, 7}, which indicates that the DL TTI length allowed to be used by the logical channel is 2 symbols, and the UL TTI length is 7 symbols, etc.

TABLE 1

In another example approach, the network device may be configured separately for the uplink TTI and/or the downlink TTI of each logical channel; for example, when configuring the logical channel 1, the DL TTI length allowed to be used by the logical channel 1 is 2 symbols, and the UL TTI length is 7 symbols; for example, the predetermined mapping method can be as shown in table 2.

Configuring parameters	2	7	14
				Index	0	1	2

TABLE 2

In yet another example method, the network device may collectively configure the TTI lengths of the logical channels, such as configuring a minimum TTI length and a maximum TTI length allowed for use by the entire UE; the terminal device may then determine the specific TTI length for each logical channel within the above scale.

In yet another example approach, the network device may perform TTI length configuration for each logical channel (without distinguishing DL and UL), such as configuring logical channel 1 for 2 symbols and 1ms, logical channel 2 for 7 symbols, etc.;

the TTI parameters allowed to be used by each logical channel may be configured through higher layer signaling, such as RRC signaling.

S23: the terminal equipment determines at least one token accumulation variable Bj according to the first TTI parameter, wherein each token accumulation variable is maintained by a logic channel or UE;

s24: and the terminal equipment multiplexes the logical channels according to at least one token accumulation variable Bj.

In the embodiment of the present application, a plurality of logical channels are multiplexed into one transport channel, and the process is as follows: firstly, judging whether a token accumulation variable Bj corresponding to each logic channel is greater than zero; if the token accumulation variable Bj of a certain logical channel is less than zero, the logical channel is not mapped to the transmission channel; if the token accumulation variable Bj of the logical channel is greater than zero, comparing the priority of the logical channel with Bj greater than zero, and preferentially mapping the logical channel with high priority to the transmission channel.

As can be seen from the above, in the embodiment of the present application, first, the terminal device obtains a first TTI parameter, then obtains a second TTI parameter according to the first TTI parameter, and determines at least one Bj according to the second TTI parameter; and finally, multiplexing the logical channels according to at least one Bj. Since the TTI parameter in the application is configurable, different STTI parameters can be configured for the logic channel according to the STTI scene, thereby solving the problem of logic channel multiplexing under the STTI scene.

In another possible embodiment of the present application, the terminal device may configure at least one TTI parameter for each logical channel of the terminal specifically according to a first TTI parameter, where the first TTI parameter may specifically be at least one of an uplink TTI parameter and a downlink TTI parameter; the uplink TTI parameter may also be one or more, and the downlink TTI parameter may also be one or more.

The terminal device may specifically obtain a first TTI parameter from the TTI parameters allowed to be used by the multiple logical channels, where the process specifically includes:

the terminal device may specifically obtain a first TTI parameter from uplink TTI parameters allowed to be used by multiple logical channels;

the first TTI parameter may specifically be a maximum TTI parameter, a minimum TTI parameter, or any TTI parameter of all uplink TTI parameters allowed to be used by the plurality of logical channels.

Or, the terminal device may specifically obtain a first TTI parameter from downlink TTI parameters allowed to be used by multiple logical channels;

the first TTI parameter may specifically be a maximum TTI parameter, a minimum TTI parameter, or any TTI parameter of all downlink TTI parameters allowed to be used by the plurality of logical channels.

Or, the terminal device may specifically obtain the first TTI parameter from the uplink TTI parameter and the downlink TTI parameter allowed to be used by the multiple logical channels;

or, the terminal device specifically acquires a first TTI parameter from a plurality of TTI parameters allowed to be used by a logical channel;

the terminal device may specifically obtain a maximum TTI parameter, a minimum TTI parameter, or any TTI parameter from all uplink TTI parameters and downlink TTI parameters allowed to be used by the plurality of logical channels.

In this embodiment, after obtaining the first TTI parameter, the terminal device may specifically set the token accumulation variables Bj of the multiple logical channels according to the first TTI parameter.

In the application, in order to facilitate the multiplexing of the logical channels, each logical channel maintains a token accumulation variable Bj, the initial value of Bj is zero, but each logical channel is accumulated according to the following formula;

bj + ═ TTI × PBR; formula (1)

The PBR is a Prioritized Bit Rate (Prioritized Bit Rate), and the PBR is set according to the priority of the logical channel, and the priorities of the logical channels are different, and the PBRs corresponding to the logical channels are also different.

In this application, the TTIs in equation (1) of the above-mentioned multiple logical channels may all be set as the first TTI parameter.

For example, the plurality of logical channels are specifically a logical channel 1 and a logical channel 2, the TTI of the logical channel 1 is 0.5ms and 0.7ms, and the TTI of the logical channel 2 is 1ms and 0.2 ms; the smallest TTI is selected among all TTIs of logical channel 1 and logical channel 2 as the first TTI parameter, which is, for example, 0.2 ms.

It should be understood that in the present application, both logical channel 1 and logical channel 2 maintain one Bj for logical multiplexing. Let Bj of logical channel a be Bj1, Bj1+ (TTI (1) × PBR (1), Bj of logical channel 2 be Bj2, Bj2+ (TTI (2) × PBR (2); in the present application, TTI (1) in Bj1 and TTI (2) in Bj2 may each be set to 0.2 ms.

In another possible embodiment of the present application, for convenience of description, a logical channel of the terminal device is set as the target logical channel. It should be understood that the target logical channel may be any logical channel of the terminal device, and the target logical channel has no limitation to the logical channel, and is only for convenience of description.

In this application, the terminal device may specifically determine the first TTI parameter from the uplink TTI parameters allowed to be used by the target logic information.

It should be noted that the uplink TTI parameter of the target logical channel may be embodied as one or more. When the uplink TTI parameter of the target logical channel is one, the TTI parameter may be directly used as the first TTI parameter. When the uplink TTI parameter of the target logical channel is multiple, a maximum TTI parameter, a minimum TTI parameter, or any one TTI parameter may be selected as the first TTI parameter from among the multiple uplink TTI parameters.

Or, the terminal device may determine the first TTI parameter from the downlink TTI parameters allowed to be used by the target logic information.

It should be noted that the downlink TTI parameter of the target logical channel may be embodied as one or more. When the downlink TTI parameter of the target logical channel is one, the TTI parameter is directly used as the first TTI parameter. When the number of the downlink TTI parameters of the target logical channel is multiple, a maximum TTI parameter, a minimum TTI parameter, or any one TTI parameter may be selected as the first TTI parameter from the multiple downlink TTI parameters.

Or, the terminal device may determine the first TTI parameter from the uplink TTI parameter and the downlink TTI parameter allowed to be used by the target logical channel.

It should be noted that the terminal device may select a maximum TTI parameter, a minimum TTI parameter, or any one TTI parameter from the uplink TTI parameter and the downlink TTI parameter allowed to be used by the target logical channel as the first TTI parameter.

Alternatively, the terminal device may determine the first TTI parameter from the TTI parameters allowed to be used by the target logical information.

It should be noted that the TTI parameter of the target logical channel may be embodied as one or more. When the TTI parameter of the target logical channel is one, the TTI parameter may be directly used as the first TTI parameter. When the target logical channel has a plurality of TTI parameters, a maximum TTI parameter, a minimum TTI parameter, or any one of the TTI parameters may be selected as the first TTI parameter.

And finally, the first TTI parameter is used for determining a token accumulation variable of the target logical channel.

Note that, assuming that the target logical information is logical channel 3, Bj3+ ═ TTI (3) × PBR (3). In this embodiment, only the first TTI parameter obtained from the TTI parameter of the target logical channel is taken as TTI (3) in Bj3 +.

For example, assuming that the terminal device has logical channels 1 to 10, 10 logical channels, each logical channel can be used as the target logic, and the corresponding tti (n) in Bjn + ═ tti (n) × pbr (n) is set according to the above method.

It should be noted that the embodiments of the present application mainly differ from the above embodiments in that: in the above embodiment, a reference is determined from TTI parameters of a plurality of logical channels, and then sizes of TTIs in Bj + ═ TTI × PBR of the plurality of logical channels are set to be consistent. In the embodiment of the present invention, each logical channel independently sets a TTI in the corresponding Bj + ═ TTI × PBR, and the TTI in each logical channel Bj + ═ TTI × PBR may be different.

In another possible embodiment of the present application, a method for receiving a random access response is also provided, and the method is mainly applied to random access in an STTI scenario.

S32: the network device receives a preamble.

S33: the network device sends an RAR (Random Access Response) to the terminal device.

S34: the terminal equipment calculates a random access radio Network Temporary Identity (RA-RNTI) according to the number or the Identity of the TTI of the preamble.

Two ways of calculating RA-RNTI are provided by way of example, and should not be construed as limiting the present application.

One is as follows: calculating RA-RNTI according to the number of TTI of preamble, and conforming to the following formula:

RA-RNTI＝M1+N1*subframe_id+K1*f_id+F1*sT_id；

wherein, the RA-RNTI represents a radio network temporary identifier, and the subframe _ id represents the number of the subframe where the preamble is sent; the f _ id is an index of the preamble on a frequency domain, and the sT _ id is a serial number of a TTI of a time domain where the preamble is sent; for example, as shown in fig. 4, 1 radio subframe is 1ms, and includes a first STTI and a second STTI, and both the first STTI and the second STTI are 0.5 ms. In this application, if the first STTI is used to send the preamble, the value of the sT _ id may be 0, and if the second STTI is used to send the preamble, the value of the sT _ id may be 1. M1, N2, K1 and F1 are integers, and exemplary M1 and N1 may be 1, K1 may be 10, and F1 may be 60

One is as follows: calculating RA _ RNTI according to the identifier of the preamble, and according to the following formula:

RA-RNTI＝M2+N2*subframe_id+K2*f_id+F2×Prach_id；

wherein, the RA-RNTI represents a radio network temporary identifier, and the subframe _ id represents the number of the subframe where the preamble is sent; the f _ id is an index of the preamble on the frequency domain, the Prach _ id represents the number of the preamble, for example, 128 preambles, and currently, in the random access process, the 60 th preamble is used, and the Prach _ id represents the identifier corresponding to 60. M2, N2, K2 and F2 are integers, and exemplary M2 and N2 may be 1, K2 may be 10 and F2 may be 60.

S35: and the terminal equipment receives the RAR of the network equipment according to the RA-RNTI.

Optionally, the terminal device calculates a time window for receiving the RAR according to the TTI of the preamble;

illustratively, according to the TTI parameter of preamble, the time window of RAR is calculated, which conforms to the following procedures:

the effective time of the start of the RAR time window is +3 × TTI of the subframe sending the preamble.

Wherein, the TTI refers to TTI length adopted for sending preamble; and if the Preamble is transmitted across a plurality of subframes in the time domain, the "subframe transmitting the Preamble" in the above formula refers to the number of the last subframe transmitting the Preamble.

The effective execution time of the RAR time window is N TTI;

wherein, N is an integer, and the TTI refers to a TTI length used for sending the Preamble, for example, the TTI may be 0.5ms, 1ms, or the like.

And the terminal equipment receives the RAR of the network equipment in the time window of the RAR according to the RA-RNTI.

It should be understood that within the time window of RAR, the network device may send RAR to multiple terminal devices; in this application, according to the calculated RNTI, the terminal device may determine, from the plurality of RARs, an RAR that the network device sends to itself.

Note that in the prior art, the terminal calculates RA-RNTI in units of subframes (1 subframe, 1 ms); in an STTI scene, TTI for sending the preambles may be less than 1ms, a mode in the prior art is adopted, if a plurality of preambles are sent in one subframe, RA-RNTIs of all the preambles in one subframe are the same by adopting the prior mode, and then corresponding RARs cannot be received according to the RA-RNTIs; the method of the application adopts the STTI for sending the preamble or the coding of the preamble as the reference, so that RA-RNTIs of a plurality of preambles sent in one subframe are different, thereby being convenient for distinguishing RARs of different preambles.

In yet another possible embodiment of the present application, a triggering method is disclosed, as shown in fig. 5, including:

s51: the terminal equipment determines that a logical channel of service data to be transmitted has data transmission;

wherein, the transmission time interval allowed by the logical channel is less than 1 ms;

s52: the terminal device triggers a first type of Buffer Status Report (BSR),

wherein the first BSR indicates that the BSR is transmitted on a second logical channel, and the TTI length allowed to be used by the second logical channel is greater than or equal to the transmission time interval allowed to be used by the logical channel;

optionally, when there is no uplink grant for the TTI allowed to be used by the logical channel, the terminal device triggers a Scheduling Request (SR); the SR indicates that there is transmission uplink data on the second logical channel.

Illustratively, the allowed TTI length of the third logical channel is 2 symbols, and the allowed TTI length of the fourth logical channel is 7 symbols, then when there is a need to transmit data in the third logical channel, a first type BSR is triggered, which may indicate that both the third and fourth logical channels have BSRs to transmit because the allowed TTI lengths (2 symbols and 7 symbols) of the third and fourth channels are greater than or equal to the allowed TTI length (2 symbols) of the third logical channel. .

For example, when the terminal device does not receive the uplink grant for the 2 symbols of the logical channel, the terminal device may trigger an SR, where the SR may indicate that the allowed TTI length of the logical channel for transmitting uplink data needs to be greater than or equal to 2 symbols, for example, there may be a logical channel for transmitting uplink data whose length may be 5 characters, or 7 characters, etc.
