Description

A communication method and device

technical field

The present application relates to the technical field of wireless communication, and in particular to a communication method and device.

Background technique

Narrowband Internet of Things (NB-IoT) is a network oriented to machine type communication (MTC), and it is an important network in the future communication field. Currently, research is under way to add uplink scheduling-free transmission technology to NB-IoT, where uplink scheduling-free transmission can also be called grant-free transmission or Uplink transmission in preconfigured resources or transmission inpreconfigured UL resources, etc. In the uplink scheduling-free transmission technology, the base station can pre-configure uplink resources for the terminal equipment. When the terminal device needs to transmit uplink data, the terminal device can directly perform uplink data transmission on preconfigured uplink resources (preconfigured uplink resources, PUR). For the uplink scheduling-free transmission technology, the terminal equipment does not need to apply for uplink transmission resources from the base station, and does not need to wait for the base station to issue uplink transmission scheduling information, which reduces the signaling process and has the advantages of reducing power consumption delay and signaling overhead.

In the uplink scheduling-free transmission technology, the PUR scheduled by the base station to the terminal equipment is periodic. In a PUR cycle, when the terminal device has data to send, it can wake up from the sleep state and send data in the PUR cycle of the PUR cycle; when the terminal device has no data to send, it can skip (skip) the PUR cycle PUR, that is, the terminal device can continue to sleep, which in turn can reduce the power consumption of the terminal device.

Due to various reasons, the PUR configured by the base station for the terminal device may need to be released or reconfigured. For example, the current network resources are tight and resources need to be released for other terminal devices; or when the terminal device skips the PUR multiple times, the resources can be released. to avoid wasting resources. If the base station releases the PUR through a paging process, it needs to wake up all terminal devices by sending paging messages on all paging occasions (POs), and indicate to all terminal devices the PUR that needs to be released or reconfigured. This method may wake up the terminal device that should not be woken up, thereby increasing the power consumption of the terminal device. Therefore, how to reduce the power consumption of the terminal equipment when releasing or reconfiguring the PUR is an urgent problem to be solved.

In combination with the foregoing description, as shown in FIG. 2 , it is a schematic flowchart of a communication method provided by an embodiment of the present application. Referring to Figure 2, the method includes:

Step 201: The terminal device determines the first resource that the terminal device can use for uplink data transmission according to the configuration information of the PUR.

The first resource includes at least one PUR, the PUR is a periodic resource, one PUR corresponds to one PUR period, and each PUR period includes one PUR. For example, at least one PUR included in the first resource may be as shown in FIG. 3 .

Step 202: After determining the first resource, the terminal device monitors a PDCCH search space every time a first time period elapses, and detects first indication information from a network device in the PDCCH search space.

Wherein, the first indication information is used to indicate one or more of the following: indicating whether to release the PUR of the terminal device; indicating whether the PUR of the terminal device is valid; indicating reconfiguration of the PUR of the terminal device; indicating the terminal The device initiates random access.

In a possible implementation manner, the first indication information is used to indicate whether to release all PURs or M PURs of the terminal device, where M is an integer greater than 0.

For example, the terminal device and the network device may agree in advance that when the value of the first indication information is the first value, it means that all PURs or M PURs of the terminal device are released; when the value of the first indication information is When it is the second value, it means that all PURs or M PURs of the terminal device are not released, that is, it means that all PURs or M PURs of the terminal device are valid.

For example, when the first instruction information is used to indicate the release of M PURs of the terminal device, it means releasing the M PURs after the moment when the terminal device receives the first instruction information. At this time, the terminal device receives the first After the indication information, the M PURs after the first indication information are no longer used.

In a possible implementation manner, the first indication information is used to indicate whether all PURs or M PURs of the terminal device are valid. For example, the terminal device and the network device may agree in advance that when the value of the first indication information is the third value, it means that all PURs or M PURs of the terminal device are valid; when the value of the first indication information is When it is the second value, it means that all PURs or M PURs of the terminal device are invalid, that is, it means that all PURs or M PURs of the terminal device are released.

For example, when the first indication information is used to indicate that the M PURs of the terminal device are valid, it means that the M PURs after the terminal device receives the first indication information are valid. At this time, the terminal device receives the first After the instruction information, the M PURs after the first instruction information can be used, but the terminal device cannot use the PURs starting from the M+1th PUR.

In a possible implementation manner, the first indication information is used to reconfigure all PURs or M PURs of the terminal device. How to specifically reconfigure all PURs or M PURs of the terminal device is not limited here. When the first indication information is used to reconfigure M PURs of the terminal device, the M PURs may refer to M PURs of the terminal device after the moment when the first indication information is received.

In a possible implementation manner, the first indication information is used to instruct the terminal device to initiate random access. For example, when the first indication information is used to instruct the terminal device to initiate random access, the first indication information may be a PDCCH order (order).

When the first indication information is used to instruct the terminal device to initiate random access, if the terminal device detects the first indication information in the PDCCH search space, the terminal device may The first indication information initiates random access.

In the first implementation manner, the terminal device may receive second indication information from the network device during the random access process; wherein the second indication information is used to indicate whether to release the terminal device The PUR of the terminal device, or the second indication information is used to indicate whether the PUR of the terminal device is valid, or the second indication information is used to reconfigure the PUR of the terminal device.

In a second implementation manner, the terminal device may receive second indication information from the network device after establishing a connection with the network device through the random access procedure.

Step 203: The network device determines a first resource for the terminal device.

The first resource includes at least one preconfigured uplink resource PUR, and the PUR is a periodic resource.

Step 204: After the network device determines the first resource, the network device determines first indication information every time a first time period elapses, and sends the first indication information in a PDCCH search space.

In step 201, the PUR configuration information may be sent by the network device through a radio resource control (radio resource control, RRC) message, or may be notified to the terminal device in other ways, which is not limited in this embodiment of the present application.

The configuration information of the PUR may indicate the number of resources included in the first resource, the occupied bandwidth, etc. The embodiment of the present application does not limit the specific content of the configuration information of the PUR, which will not be repeated here.

In step 202, the first duration may be a duration corresponding to N PUR periods, each PUR period includes one PUR, and N is an integer greater than 0. N may be a value configured by the network device, or may be a value agreed between the network device and the terminal device, which is not limited in this embodiment of the present application.

As mentioned above, since the first duration may be the duration corresponding to N PUR periods, in this embodiment of the application, the terminal device may start a counter and set The initial value of the counter is 1; every time a PUR period passes, the count value of the counter is increased by 1, and when the count value of the counter is N, regardless of whether the terminal device sends uplink data on the second resource, the The terminal device monitors the PDCCH search space. Wherein, the second resource is the last PUR in the first duration. The third indication information is used to configure at least one PUR for the terminal device. In a possible implementation manner, the third indication information may be configuration information of the PUR in step 201 .

Exemplarily, in a possible implementation manner, during the counting process of the counter, when the terminal device determines that the first preset condition is satisfied, the counter may be reset to 1. Through this method, the frequency at which the terminal equipment monitors the PDCCH search space can be reduced, thereby further reducing the power consumption of the terminal equipment.

In a possible implementation manner, the first preset condition is any one of the following, or a combination of at least one:

Condition 1, the count value of the counter is N; when the count value of the counter is N, it means that the terminal device has skipped at least N PURs and has not transmitted data. At this time, the terminal device can monitor the PDCCH search space, thereby determining that the network device is Whether the uplink resource pre-configured by the terminal device is still valid.

Condition 2: The terminal device sends uplink data; Exemplarily, the terminal device sends uplink data through PUR in the first resource. According to the prior art, after the terminal device sends the uplink data, it needs to monitor the PDCCH search space, so as to detect in the PDCCH search space whether the network device sends the acknowledgment (acknowledge) message of the uplink data, so after the terminal device sends the uplink data, The counter can be reset to an initial value of 1, thereby reducing the frequency at which the terminal equipment monitors the PDCCH search space, and reducing the power consumption of the terminal equipment.

Condition three, the terminal device receives fourth indication information from the network device, where the fourth indication information is used to indicate that all PURs or K PURs of the terminal device are valid, where K is an integer greater than 0. For example, after the terminal device sends uplink data in one PUR, the network device may feed back the fourth indication information when receiving the uplink data. The terminal device can determine according to the fourth indication information that all PURs or K PURs of the terminal device are still valid, so there is no need to monitor the PDCCH search space in the current counting period of the counter, so that the counter can be reset to the initial value 1, reducing The terminal equipment monitors the frequency of the PDCCH search space to reduce the power consumption of the terminal equipment.

Of course, the above are only examples, and the first preset condition may also include other conditions, which will not be described here one by one.

In the embodiment of the present application, every time the first time period passes, the terminal device starts to monitor the PDCCH search space at the end of the first time period. When the terminal device determines the first duration through the counter, the terminal device starts to monitor the PDCCH search space when the value of the counter is N, and the duration of monitoring the PDCCH search space may be a configured duration of the network device or a pre-agreed duration. In a possible implementation manner, when the terminal device sends uplink data in the second resource, the terminal device may monitor the PDCCH search space within a second duration after the second resource. For example, the terminal device starts a timer after sending the uplink data in the second resource, and monitors the PDCCH search space before the timer expires (expires) or stops (stops). Wherein, the timing duration of the timer is a second duration, and the second duration is a duration configured by the network device or a pre-agreed duration.

In a possible implementation manner, when the terminal device does not send uplink data in the second resource, the terminal device monitors the PDCCH search space within a third time period after the second resource. For example, the terminal device starts a timer at the end of the second resource, and monitors the PDCCH search space before the timer times out or stops. Wherein, the timing duration of the timer is a third duration, and the third duration is also a duration configured by the network device or a pre-agreed duration, and the second duration may be greater than or equal to the third duration.

In the above method, when the terminal device does not send uplink data in the second resource, the network device does not need to process the uplink data of the terminal device. Send the first indication information. Therefore, when the terminal device does not send uplink data in the second resource, it can reduce the duration of monitoring the PDCCH search space and reduce the power consumption of the terminal device.

In a possible implementation manner, when the terminal device detects the first indication information in the PDCCH search space, the terminal device may send an acknowledgment message to the network device, and the acknowledgment message is used to indicate that the The first indication information is successfully received. Through this method, the network device can determine whether the terminal device successfully receives the first indication information.

In a possible implementation manner, when the terminal device does not detect the first indication information in the PDCCH search space, the terminal device determines that all PURs of the terminal device continue to be valid. Or, in another possible implementation manner, when the terminal device does not detect the first indication information in the PDCCH search space, the terminal device determines that all PURs of the terminal device are released.

In step 203, how the network device specifically determines the first resource for the terminal device is not limited in this embodiment of the present application, and will not be repeated here.

In step 204, after the network device determines the first resource, it may send third indication information to the terminal device, and the network device starts a counter when sending the third indication information, and sets the initial value of the counter to 1;

Every time a PUR period passes, the count value of the counter is increased by 1, and when the count value of the counter is N, the network device sends the first indication information in the PDCCH search space.

For specific content of the first indication information, reference may be made to the description in step 201, which will not be repeated here. It should be noted that, when the first indication information is a PDCCH order, if the terminal device initiates random access according to the first indication information, in the first implementation manner, the network device may 4 carries second indication information, the second indication information is used to indicate whether to release the PUR of the terminal device, or the second indication information is used to indicate whether the PUR of the terminal device is valid, or the second The indication information is used to reconfigure the PUR of the terminal device. In the second implementation manner, after the network device establishes a connection with the terminal device through random access, it may send the second indication information to the terminal device. At this time, the second indication information may be carried by a radio resource control (radio resource control, RRC) message .

Exemplarily, in a possible implementation manner, when the first indication information is a PDCCH order, the network device may use downlink control information (downlink control information, DCI) to carry the first indication information. The format of the DCI may be DCI format N1.

In another possible implementation manner, when the first indication information is used to indicate whether to release the PUR of the terminal device, or to indicate whether the PUR of the terminal device is valid, or to indicate to reconfigure the PUR of the terminal device During the PUR, the format of the DCI carrying the first indication information may be a format other than the DCI format N0 and DCIformat N1 in the prior art, that is, a redesigned format. Optionally, in order not to increase the complexity of detecting the first indication information by the terminal device, the bit width of the redesigned DCI is the same as that of the DCI format N1, which is 23 bits. When the terminal device detects the first indication information carried by the DCI in the PDCCH search space, the terminal device may send an acknowledgment message to the network device. When the terminal device does not detect the first indication information carried by the DCI in the PDCCH search space, the terminal device may determine that all PURs of the terminal device are still valid or released.

Exemplarily, in a possible implementation manner, when the network device determines that the second preset condition is satisfied during the counting process of the counter, the value of the counter is reset to 1. Through this method, the frequency of sending the first indication information can be reduced, thereby improving resource utilization.

In a possible implementation manner, the second preset condition is any one of the following, or a combination of at least one:
