Background

The communication network system has a large scale, and the base stations are deployed in the network with high density, so that the power consumption of the base stations is large, and therefore, the cost of energy consumption is high.

In R16, a wake-up signal (WUS) is introduced to dynamically wake up the UE for the next on time. The configuration of C-DRX has a tradeoff between network energy saving and UE performance (such as scheduling delay), for example, a large C-DRX cycle is preferred to improve the energy saving effect, but the UE scheduling delay is increased; the C-DRX based on RRC signaling configuration is used for network energy saving and has the problem of large signaling overhead, so that the network side needs to research an energy saving mechanism.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a method for discontinuously transmitting and receiving a network, which realizes network energy saving in a wireless communication system, wherein the wireless communication system comprises network equipment and terminal equipment.

If the network is introduced for discontinuous transmission, the network side needs to judge the opening and closing according to the real-time network load condition, so that auxiliary information of some terminals is needed. In addition, when the network side is in the off state, on one hand, the terminal is in a non-connected state under network coverage, so that when the terminal enters a network coverage range, the network side needs to periodically wake up to transmit a necessary synchronization signal, and on the other hand, the network cannot receive the auxiliary information of the terminal in the off state, so that the network side needs to consider receiving the auxiliary information of the terminal in the periodic wake up state for network on transmission.

If the network is introduced to receive discontinuously, the network side also introduces auxiliary information from the terminal for the network side to be in a sleep period or an activation period, and in consideration of the configuration of multiple sets of authorization-free scheduling introduced into the uplink authorization-free scheduling scheme, in order to save energy consumption, the network device needs to monitor necessary uplink authorization-free scheduling resources according to the indication of the terminal device, and does not need to monitor all uplink resources which are not indicated and are scheduled without authorization, which is beneficial to saving energy consumption.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The application provides a method for discontinuous network transmission and reception, which is used for network equipment and/or terminal equipment in a wireless communication system and comprises the following states: a first state in which a signal is normally transmitted; a second state, no signal is transmitted; further comprising at least one of the following states: a third state, transmitting the set signal; and a fourth state, in which the signal is transmitted discontinuously.

The method also includes switching between the above at least 2 states. For example, the following steps are included: switching from the first state to the second state in response to a condition of a connectionless terminal. When the method is used for the network equipment and the network equipment is in the first state, if the terminal equipment without the connection state is detected, the terminal equipment is directly switched to the second state.

The present application also includes the following examples 1 to 3.

Example 1: as a method for saving energy of a wireless network, a network device includes a first state, a second state and a third state, the first state is a non-energy-saving state (normal state) of the network, the second state is a complete energy-saving state, a base station does not send any signal, the third state is a partial energy-saving state, and the base station only sends and receives a set signal.

FIG. 1 is a schematic diagram of an embodiment of the method of the present application including first, second, and third states.

The network device periodically works in the third state, the period is T, and the transmission duration is D. In the third state, the set signal includes a first downlink signal, and the first downlink signal is used for synchronization or broadcast information between the network device and the terminal device.

Fig. 2 shows an example of a first downlink signal format. And the network equipment sends a first downlink signal when in the third state, wherein the first downlink signal is used for synchronization of the network equipment and the terminal or sending of broadcast information.

For example, the first downlink signal may be a primary synchronization signal (PSS signal), the PSS signal is a pseudo-random sequence with a length of 127, a frequency domain BPSK M sequence is adopted, and 3 cycles are positions of 0/43/86. The PSS is mapped to continuous 127 subcarriers in the middle of 12 PRBs, 144 subcarriers are occupied, 8/9 subcarriers are respectively used as guard bands on two sides, and the guard bands are transmitted at zero power and are used for downlink synchronization of network equipment and terminal equipment.

For example, the first downlink signal may be a long-period SSB signal, such as a transmission period of 80ms, used for downlink synchronization of the network device and the terminal device, and reception of broadcast signaling. The PSS/SSS (primary and secondary synchronization signal) and PBCH (broadcast channel) blocks are always bound in one physical resource, called SSB block. In an SSB block, symbols 0 to 3 are occupied in the time domain, and a total of 4 symbols are distributed in the frequency domain over 240 consecutive subcarriers (20 RBs). Within the SSB block, a fixed distribution pattern is employed.

For example, the first downlink signal may also be a modified SSB signal, such as a transmission period of 160ms, for downlink synchronization of the network device and the terminal device and reception of broadcast signaling, where 80ms only transmits the PSS signal and does not transmit the SIB broadcast signaling (PBCH).

Further, the signal set in the third state further includes a first uplink signal; switching from the third state to the first state or the second state in response to the first upstream signal.

For example, the network device receives a first uplink signal from the terminal device in the third state, and determines to switch to the second state or the first state after the third state according to the first uplink signal.

For example, the first uplink signal may be a Zadoff-Chu sequence, and the ZC sequence may generate a plurality of sequences by cyclic shift according to the root index sequence, and has characteristics of good autocorrelation and cross-correlation, constant amplitude, low peak-to-average ratio, and the like. According to a ZC sequence of length L =839 or L =139, x (i) = e (-j × pi u × i (i + 1)/L). The position of the frequency domain is the fixed bandwidth of the middle frequency. The time domain position is a fixed time, such as 1ms or 3.5ms. This is applicable to the case where the first downlink signal is the PSS signal.

For example, the first uplink signal may also be a Zadoff-Chu sequence, and the position of the frequency domain and the position of the time domain are indicated by the broadcast signaling, which is suitable for the case where the first downlink signal is a long-period SSB signal or an improved SSB signal.

For example, the transmit beam direction of the first uplink signal is selected according to the receive beam direction of the first downlink signal.

Further, in the third state, a set first duration is satisfied between the network device sending the first downlink signal and receiving the first uplink signal. Or the terminal device sends the first uplink signal after the first duration after detecting the first downlink signal. The first duration is a parameter associated with the processing capability of the terminal device or a parameter indicated through signaling.

For example, when the first downlink signal is the PSS signal, the terminal device transmits the first uplink signal for a first duration, where the first duration is determined by the capability of the terminal device.

For example, when the first downlink signal is an SSB signal or an improved SSB signal, the terminal device may obtain the system information, and send the first uplink signal after a first duration indicated by the system information.

Further, the network device monitors the first uplink signal in a specified time period and duration, if the first uplink signal is not monitored, the network device continues to be in the second state (a complete energy saving state), and if the first uplink signal is monitored, the network device switches to the first state (a normal state).

The method of the present application is applied to a network device, and includes the following steps:

step 101, the network device periodically transmits the first downlink signal in the period and the transmission timing of the third state (partial energy saving state).

Step 102, the network device monitors the first uplink signal at a first time after the first downlink signal in the third state is sent.

Step 103, after the network device detects the first uplink signal, it switches to the first state (normal state) (within a set time).

step 111, the network device detects that there is no RRC connected terminal in the first state, and the network device enters the second state (power saving state).

step 121: the network device periodically transmits the first downlink signal in a cycle and a transmission timing of the third state (partial power saving state).

Step 122: the network device switches to the second state (power saving state) without detecting the first uplink signal.

Example 2: the method of the application, as a method for saving energy of a wireless network, comprises a second state, a third state and a fourth state. The second state is a complete energy-saving state, the base station does not send any signal, the third state is a partial energy-saving state, the base station only sends and receives a set signal, and the fourth state is a discontinuous reception state and comprises an active time interval and a sleep time interval which are alternated. The network equipment in the active period receives an uplink signal, and the network equipment in the sleep period does not receive the uplink signal.

FIG. 3 is a schematic diagram of an embodiment of the method of the present application including first, second, third, and fourth states. For example, for the network device, the fourth state periodically includes an active period and a sleep period, the active period is that the network device receives an uplink signal from the terminal device, and the sleep period is that the network device does not receive any uplink signal from the terminal device.

Further, the network device detects a second uplink signal when in the sleep period of the fourth state, so as to indicate whether the network device is awakened in a subsequent discontinuous reception cycle.

When the network device detects the second uplink signal, in a fourth state of discontinuous reception, the network device activates reception of the uplink signal, i.e., an activation period, otherwise, the network device continues to sleep in a subsequent discontinuous reception cycle, thereby saving energy consumption. The method is suitable for the situation that when an uplink delay sensitive or high-priority service is initiated, the terminal can switch the base station to a normal receiving state through the second uplink signal, the terminal is prevented from waiting for a long time to send a Scheduling Request (SR) or uplink data (CG PUSCH), and the network equipment detects the second uplink signal in the energy-saving state to judge whether to switch to the normal state to receive other uplink transmission data.

Further, the second uplink signal is indicated by 1 bit, and "1" indicates that the base station is in an active period after being awakened; a "0" indicates that the base station continues to be in the sleep period without activating reception.

Further, the terminal sends a second uplink signal in a second time length (Soffset) before the base station activates and receives. The base station listens for a second uplink signal for a second duration before being ready to activate. The second duration may be predefined or indicated in the second uplink signal.

If the base station monitors that the second uplink signal is '1', the base station starts the activated period in the next discontinuous receiving period, otherwise, the base station continues to be in the sleep period.

Further, the second uplink signal is configured to be transmitted on a PUCCH format 0 or PUCCH format1 channel. And the high-level signaling configures the resource ID, the offset and the uplink control channel resource of the second uplink signal.

step 201, when the network device is in the fourth state, waking up a second duration before the receiving function, and monitoring a second uplink signal sent from the terminal device.

Step 202, if the network device detects the second uplink signal, the network device wakes up the receiving function, and if the second uplink signal is not detected, the network device continues to be in the sleep period.

Steps 201 to 202 are executed periodically.

Example 3: the method is used as a wireless network energy-saving method, and network equipment comprises a second state, a third state and a fourth state, wherein the second state is a complete energy-saving state, a base station does not send any signal, the third state is a partial energy-saving state, the base station only sends and receives a set signal, and the fourth state is a discontinuous receiving state. The fourth state periodically comprises an active period and a sleep period, wherein the active period is that the network equipment receives the uplink signal from the terminal equipment, and the sleep period is that the network equipment does not receive any uplink signal from the terminal equipment.

When the network device is in the active period of the fourth state, the third uplink signal is detected, so as to assist the network device to receive multiple sets of uplink grant-free transmission data, that is, the network device only monitors the uplink resource of the uplink grant-free scheduling indicated by the third uplink signal.

Considering that the network device does not need to monitor the uplink resource of the non-indicated uplink authorization-free scheduling, the energy consumption is saved. The method is suitable for monitoring necessary uplink authorization-free scheduling resources according to the indication of the terminal equipment by the network equipment when a plurality of sets of uplink authorization-free scheduling resources are configured, and energy consumption is saved.

In order to implement the scheme, the terminal equipment periodically transmits the third uplink signal, and the transmission period and the transmission opportunity are configured by signaling.

For example, when the period of the multiple sets of unlicensed scheduling configurations is at a symbol level, a third uplink signal is sent once in a period of 1ms, indicating the uplink grant transmission that the network needs to monitor in the next time slot. And when the period configured by the multiple sets of the authorization-free scheduling is in a time slot level, the maximum time slot of the configured authorization-free transmission is used as the period to send a third uplink signal for one time, and the uplink authorization transmission which needs to be monitored by the next time slot network is indicated.

Preferably, the third uplink signal configuration is sent on PUCCH format 2, PUCCH format3, or PUCCH format 4, and is used to assist the network device to receive uplink data on N sets of uplink grant-free transmissions.

For example, the number of bits sent is log2 (N) bits, which is used to indicate one of N sets of unlicensed scheduled uplink grant transmissions. For example, when N =12, a 4-bit indication is required.

Preferably, the network device configures N common time-frequency resources of the terminal device for transmitting the third uplink signal, where the nth (N is greater than 1 and less than or equal to N) time-frequency resource indicates that there is the nth set of uplink grant-free data to be transmitted. For example, the transmitted third uplink signal is n ZC sequences, and the nth sequence is transmitted on the nth time-frequency resource. For example, terminal 1 has traffic to send in the first set of uplink transmissions for unlicensed scheduling, and sends the first ZC sequence on the first time-frequency resource, terminal 2 has traffic to send in the second set of uplink transmissions for unlicensed scheduling, and sends the second ZC sequence on the second time-frequency resource, and terminal 3 has traffic to send in the first set of uplink transmissions for unlicensed scheduling, and also sends the first ZC sequence on the first time-frequency resource. The base station can simultaneously acquire the sending time of the 1 st set and the 2 nd set of unlicensed scheduling uplink transmission needing to be monitored during detection. Meanwhile, the terminal 1 and the terminal 3 realize a multi-user diversity function, which is beneficial for the network equipment to detect the third uplink signal more reliably.

The method is used for network equipment and comprises the following steps

Step 301, the network device periodically detects the third uplink signal within the periodic wake-up receiving time of the fourth state.

Step 302, the network device detects that the third uplink signal includes data to be sent in the 1 st and 2 nd sets of unlicensed scheduled uplink transmissions, and the network device only needs to periodically detect the 1 st and 2 nd sets of unlicensed scheduled uplink resources in the awake receiving state.

Fig. 4 is a schematic diagram illustrating the sleep period and the active period switching in the fourth state. Further preferably, the method further comprises the following steps: and in the sleep period, responding to a second uplink signal, and switching to the active period or keeping the sleep period. Further, a set second duration is satisfied between the second uplink signal and the activation period. Further, the second uplink signal is configured to be PUCCH format 0 or PUCCH format 1.

Fig. 5 is a third uplink signal structure embodiment.

Or, further preferably, further comprising the steps of: and in the activation period, responding to a third uplink signal, and determining the uplink resource free from the authorized scheduling. Further, the third uplink signal is configured to be PUCCH format 2, PUCCH format3, or PUCCH format 4. Further preferably, the index of the time-frequency resource of the third uplink signal is used to indicate an index of uplink grant-free scheduling data.
