Description

Carrier wave sending method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a carrier transmission method and apparatus.

Background

As one of the Control channels in the Global System for Mobile communications (GSM), a GSM Broadcast Control Channel (BCCH) carrier may be used to send Broadcast messages and as a common pilot for a cell. Wherein full power transmission must be sustained in order for all users in the cell to be able to receive both system messages and paging messages. This causes the GSM BCCH carrier to occupy higher power resources when idle and causes greater interference within the network.

As the mobile communication technology is evolving to a higher-level version, for example, to the fifth generation mobile communication technology (5th generation, 5G), the GSM network load is lower and lower, and how to reduce the power consumption of the GSM BCCH carrier and the intra-network interference becomes a concern of the operator.

In order to reduce the power consumption of the GSM BCCH carrier, in the prior art, power reduction processing is performed on the non-0 time slot of the BCCH carrier to reduce the power consumption of the BCCH carrier and interference in the network, but the amplitude of adjusting the transmission power is limited, so that the energy saving and interference reduction effects are limited.

Compared with the prior art, the GSM BCCH carrier still occupies higher power resources when being idle, and causes larger interference in the network.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second" and the like in the description and drawings of the present application are used for distinguishing different objects or for distinguishing different processes for the same object, and are not used for describing a specific order of the objects.

Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.

First, technical terms related to embodiments of the present application are described:

GSM frequency point: according to the GSM standard, frequency points are divided according to 200K, and each 200K frequency is a frequency point.

BCCH frequency points: usually, each frequency point can be configured with 8 time slots, and since GSM is time division, each time slot can complete the whole function of one channel. Therefore, each frequency point can correspond to 8 channels. Each channel may define a different channel type. Generally, only one BCCH channel can be defined in a cell, which is defined as the frequency point where the BCCH channel is located, and can be regarded as the BCCH frequency point. For example, referring to fig. 3, a time slot 0 of the BCCH frequency point is configured as a BCCH channel, and time slots 1-7 of the BCCH frequency point can be respectively configured as different types of channels, for example, time slot 1 is configured as a Traffic Channel (TCH).

Continuous full power transmission: according to the GSM standard, in order for a mobile station to detect paging access and handover signals, the base station must continuously transmit radio frequency signals in all time slots (e.g., 8 time slots) of its BCCH frequency point. In one possible implementation, the transmission is always done at the maximum transmission power of the cell (so-called full power) on each time slot of the BCCH frequency point. And idle burst sequences (dummy bursts) are transmitted at full power on the BCCH frequency point even when there are no messages to be transmitted on the BCCH frequency point. Therefore, when the data to be transmitted does not exist on the BCCH frequency point, the transmitting power of the BCCH frequency point is still high, and the transmitting power consumption of the base station is increased. For example, referring to the left bar chart in fig. 3, the base station continues to transmit with full power in time slots 0-7 of a certain BCCH frequency point.

BCCH energy-saving mode transmission: in order to solve the problem of high power consumption caused by full power transmission of the base station on the BCCH frequency point, the industry proposes BCCH energy-saving mode transmission. Specifically, for example, as shown in the right bar chart in fig. 3, the base station carries the downlink synchronization channel in the 0 timeslot on a certain BCCH frequency point, and continuously transmits at full power in the timeslot. The time slots 1 to 7 are traffic-related channels, for example, time slot 1 is occupied by a TCH, time slot 2 is occupied by a Packet Data Channel (PDCH), and these channels may use a BCCH energy-saving mode to transmit data, that is, they are not continuously transmitted with full power. For example, when a certain time slot of 1-7 time slots is occupied by a service, power control with a certain amplitude can be performed, for example, the transmission power of a BCCH frequency point in the time slot is reduced by 2dB, when no service occupies the certain time slot, power control with a fixed step length is performed on dummy burst on an idle channel (for example, TCH idle of timeslot 1 of the BCCH frequency point) corresponding to the time slot of the BCCH carrier frequency, that is, on the idle channel, the transmission power of dummy burst can be dynamically adjusted. Therefore, the transmitting power of the BCCH frequency point is reduced compared with the full power, and the energy-saving performance of the base station is improved.

The network architecture according to the embodiment of the present application is given below, and referring to fig. 1, the architecture of a communication system to which the embodiment of the present application is applied is shown.

An embodiment of the present application provides a carrier transmission method, taking an access network device as a base station as an example, as shown in fig. 4, the method may include S101 to S102:

s101, in a first period, when data to be transmitted does not exist, the access network equipment sends dummy on a BCCH carrier.

In the embodiment of the present application, when referring to the BCCH carrier, it is the same as the BCCH frequency point. Therefore, the BCCH carrier and BCCH frequency points are not distinguished from each other as described later.

The first time period, which may also be referred to as a transmission time period, is when the base station turns on the function of transmitting dummy. When the base station starts the dummy burst transmission function, the base station transmits data according to a service requirement on a non-idle channel, that is, a channel occupied by a service, for example, channels corresponding to

time slots

4 and 6 in fig. 3, where the data may be transmitted at full power (that is, the maximum transmission power of a cell) or may be transmitted at a power reduced by a certain amount, which is not specifically limited in this embodiment of the present application. In an idle channel, for example, channels corresponding to

time slots

1, 2, 3, 5, and 7 in fig. 3, the base station sends dummy information, where the dummy information may be sent with full power (i.e., maximum cell transmit power), or sent with a power controlled according to a fixed step size. The channel may include, but is not limited to, one or more of the following: BCCH, Paging Channel (PCH), Traffic Channel (TCH) occupied by users, stand-Alone dedicated control channel (SDCCH) occupied by users, PDCH occupied by users, and the like.

And S102, in the second time period, when the data to be transmitted does not exist, the access network equipment does not send dummy on the BCCH carrier.

The second period may be referred to as an off period, and in the second period, the base station turns off the function of transmitting dummy. This means that data is transmitted according to the service requirement on a non-idle channel in the off period, i.e., a channel where data to be transmitted exists, and dummy information is not transmitted on an idle channel, i.e., a channel where data to be transmitted does not exist.

The sending time interval and the turn-off time interval can be divided according to different time granularities, and specifically, the following three conditions exist in the embodiment of the present application:

case 1: the method comprises the steps of dividing a sending time period and a turn-off time period by taking the time length of a SACCH frame as time granularity, specifically, the first time period is integral multiple of the time length of the SACCH frame, the second time period is integral multiple of the time length of the SACCH frame, and the time lengths of the first time period and the second time period are the same or different. At present, the SACCH frame time length is 480ms, and as the protocol evolves, the SACCH frame time length may also change, and here, the specific duration of the SACCH frame time length is not limited.

Exemplarily, as shown in fig. 5, fig. 5 exemplarily shows 2 transmission periods and 1 off period, where the black part in fig. 5 is a first period (transmission period) containing two SACCH frames, and the blank part is a second period (i.e. off period) containing 3 SACCH frames. In one possible implementation, the first time period and the second time period are cyclically cycled, i.e., each transmission period includes 2 SACCH frames, and each off period includes 3 SACCH frames. Of course, each first time period and each second time period may also be configured independently, for example, within a time period consecutive in the time domain, the first transmission period includes 2 SACCH frames, the first off period includes 3 SACCH frames, the second transmission period includes 4 SACCH frames, and the second off period includes 2 SACCH frames.

Still referring to fig. 5, the off period includes 3 SACCH frames, each SACCH frame includes a plurality of Time Division Multiple Access (TDMA) frames, fig. 5 only exemplarily shows that the third SACCH frame from left to right includes 5 TDMA frames, the SACCH may also include other TDMA frames, which are not fully shown in fig. 5. The TDMA frame includes a plurality of time slots, for example, 8 time slots such as 0 to 7 shown in fig. 5, and since the 8 time slots are included in the SACCH frame in the second time period, the time slots all belong to the off time period, that is, when there is data to be transmitted in the time slots, the data is transmitted according to the service requirement, and when there is no data to be transmitted, dummy information is not transmitted. Similarly, if one or more time slots belong to the sending time interval, the data is sent according to the service requirement when the data to be transmitted exists on the time slots, and dummy information is sent when the data to be transmitted does not exist.

Case 2: the sending time interval and the turn-off time interval are divided by taking the time length of the GSM time slot as time granularity, specifically, the first time interval is integral multiple of the time length of the GSM time slot, the second time interval is integral multiple of the time length of the GSM time slot, and the time lengths of the first time interval and the second time interval are the same or different.

Illustratively, referring to fig. 6, each TMDA frame is composed of 8 time slots, and 26 (0-25) TDMA frames are composed of a multiframe, each TDMA frame (each column) includes a certain number of transmission periods (time slots in which dummy information is transmitted) and a certain number of off periods (time slots in which dummy information is not transmitted), wherein the black portion in fig. 6 is a first period (transmission period) and the blank portion is a second period (i.e., off period). In a possible implementation, the timeslot 0 is used to carry BCCH, and since the timeslot 0 controls the whole GSM system, the transmission reliability requirement on the timeslot 0 is high, and based on this, the timeslot 0 is set as the first period. Thus, when the time slot 0 has no data to be transmitted, the dummy information is also transmitted, so that the probability of low transmission reliability caused by missing transmission of the dummy information can be reduced. Time slots 1-7 carry other traffic and, as shown in fig. 6, for TDMA frame 0, time slot 1 is set to the first period, time slots 2-4 are set to the second period, time slot 5 is set to the first period, and time slots 6-7 are set to the second period. In this case, each first period includes the same number of time slots, i.e., the first periods each include 1 time slot, the first second period includes 3 time slots, and the second period includes 2 time slots. Of course, the number of time slots included in each first period may also be independently configured, i.e., each first period may include a different number of time slots, and/or the number of time slots included in each second period may be independently configured. For example, for a TDMA frame, only the number of time slots included in the first time period is configured independently, specifically, the first time period includes 1 time slot, the first and second time periods each include 2 time slots, and the second first time period includes 2 time slots. Alternatively, only the number of slots included in the second period is independently configured. The number of time slots included in the first period and the number of time slots included in the second period may be configured independently, specifically, the first period includes 1 time slot, the first second period includes 1 time slot, the second first period includes 2 time slots, the second period includes 2 time slots, and the third first period includes 1 time slot.

It should be noted that, for a certain TDMA frame, the number of the first time periods and the number of the second time periods may be the same or different. For example, one TDMA frame may include 3 first periods and 2 second periods, and may also include 2 first periods and 2 second periods.

Of course, there are other combination ways to divide the sending period and the off period by using the time length of the GSM time slot as the time granularity, for example, changing the number of time slots included in the first period and/or changing the number of time slots included in the second period, which is not specifically limited in the embodiment of the present application.

In the scheme shown in fig. 6, when a certain timeslot is a timeslot in the first period, dummy information is still sent when there is no data to be transmitted in the timeslot. And when a certain time slot is the time slot in the second period, when the data to be transmitted does not exist on the time slot, the dummy information is not sent.

Case 3: the sending period and the off period are divided by using the GSM symbol time length as time granularity, specifically, the length of each time slot is 0.577ms, the amount of data carried is 156.25 symbols, and the time length of each GSM symbol is 3.6928 us. The first time interval is integral multiple of the time length of the GSM symbol, the second time interval is integral multiple of the time length of the GSM symbol, and the time lengths of the first time interval and the second time interval are the same or different.

Illustratively, referring to fig. 7, one slot may be divided into 8 shares on average, each share corresponding to 19.5 symbols, i.e., the transmission period and the off period are divided with a time length of 19.5 symbols as a unit time granularity. Fig. 7 exemplarily shows 2 slots, where slot 1 includes 5 transmission periods (i.e., black-filled symbols) and 3 off periods (i.e., white-filled symbols), and slot 2 includes 4 transmission periods and 4 off periods. In fig. 7, the black portion is a first period (transmission period), and the blank portion is a second period (i.e., off period), and the distribution of the first period and the second period may be configured according to a preset rule. The first time period and the second time period may be configured in a combination manner (with 19.5 symbols as a group) as shown in fig. 7, or the first time period and the second time period may be configured in a GSM symbol time length by applying other combination manners, which is not specifically limited in this embodiment of the application.

Of course, the first period and the second period may also be divided with other N (N is a positive number) symbols as unit time granularity. For example, 39 symbols as a unit time granularity.

As shown in fig. 7, if the current symbol is a symbol in the first time period, the dummy information still needs to be sent on the symbol when there is no data to be transmitted on the symbol. And if the current symbol is the symbol in the second time interval, when the symbol does not have data to be transmitted, the dummy information is not sent on the symbol.

As described above, in the three cases of dividing the transmission period and the off period, different first periods and second periods may be configured in different frequency bands, for example, in the frequency band 1 (e.g., 890.1MHZ-890.3MHZ), the transmission period and the off period are divided by using the time length of the SACCH frame as time granularity, and in the frequency band 2 (e.g., 890.3MHZ-890.5MHZ), the transmission period and the off period are divided by using the time length of the GSM time slot as time granularity, or divided by using other time granularities, for example, in the frequency band 1, each first period includes 3 SACCH frames, each second period includes 2 SACCH frames, and in the frequency band 2, the first period includes 2 SACCH frames, and each second period includes 2 SACCH frames, which is not specifically limited in this embodiment of the present application.
