Abstract

Methods and systems for techniques for coverage enhancement in wireless networks are disclosed. In one example aspect, the method includes determining, by a network device, one or more time domain windows associated with time domain resources based on capability information of a wireless device, indicating, by the network device, the one or more time domain windows, and receiving, by the network device, from the wireless device, a message according to the one or more indicated time domain windows.

First claim

What is claimed is:

1 . A method for wireless communication, comprising:
determining, by a network device, one or more time domain windows associated with time domain resources based on capability information of a wireless device; indicating, by the network device, the one or more time domain windows; and receiving, by the network device, from the wireless device, a message according to the one or more indicated time domain windows.

2 . The method of claim 1 , wherein the one or more time domain windows include at least one of a time domain window size or a starting point of a time domain window.

3 . The method of claim 2 , wherein the time domain window size includes at least one of a nominal time domain window size, an actual time domain window size, or a bundle size.

4 . The method of claim 1 , wherein the capability information includes a maximum time domain window size supported by the wireless device.

5 . The method of claim 2 , wherein the time domain window size is determined based on at least one of a number of repetitions, a number of slots, or a number of symbols.

6 . The method of claim 2 , wherein the time domain window size includes at least one nominal time domain window size, at least one actual time domain window size, and at least one bundle size.

7 . The method of claim 2 , wherein the time domain window size includes at least one nominal time domain window size and at least one bundle size.

8 . The method of claim 2 , wherein the time domain window size includes at least one nominal time domain window size, and wherein the at least one nominal time domain window size is used as a bundle for frequency hopping.

9 . A method for wireless communication, comprising:
configuring, by a network device, a time domain window of a time domain resource for joint channel estimation for a wireless device; configuring, by the network device, a starting point of the time domain window; and receiving, by the network device, from the wireless device, a message according to the starting point of the time domain window.

10 . The method of claim 9 , wherein the time domain resource includes consecutive physical resources or non-consecutive physical resources.

11 . The method of claim 9 , wherein the starting point of the time domain window is a last symbol of an uplink grant for physical uplink shared channel (PUSCH) transmission.

12 . The method of claim 9 , wherein the starting point of the time domain window is a first symbol within a period for each PUSCH or physical uplink control channel (PUCCH).

13 . The method of claim 9 , wherein the starting point of the time domain window is a starting point of each wireless frame.

14 . The method of claim 9 , wherein an offset value is configured for the wireless device to allow a time domain window sliding.

15 . The method of claim 9 , wherein the time domain window includes at least one of an actual time domain window or a nominal time domain window.

16 . The method of claim 9 , wherein the time domain window is restarted upon occurrence of a predetermined event including at least one of: consecutive PUSCH transmission; non-consecutive PUSCH transmission; a frequency domain resource block occupied by PUSCH changes; changes in PUSCH phase continuity; changes in PUSCH power control parameters; changes in PUSCH timing advance; changes in a PUSCH transmission precoding; dynamic switching by carrier aggregation (CA) uplink switching; dynamic switching of bandwidth part (BWP); dynamic switching between a normal uplink (NUL) and a supplementary uplink (SUL); or non-consecutive time domain length is greater than a predetermined number of symbols, slots or repetitions.

17 . A method for wireless communication, comprising:
transmitting, by a wireless device, to a network device, capability information for determining time domain windows associated with time domain resources; receiving, by the wireless device, from the network device, an indication of one or more time domain windows; and transmitting, by the wireless device, a message according to the one or more time domain windows.

18 . The method of claim 17 , wherein the capability information includes a maximum time domain window size supported by the wireless device, and wherein the capability information is used to determine at least one of a time domain window size or a starting point of a time domain window associated with the one or more time domain windows.

19 . The method of claim 17 , wherein a time domain window size of the one or more time domain windows includes at least one of a nominal time domain window size, an actual time domain window size, or a bundle size.

20 . The method of claim 17 , wherein a time domain window size of the one or more time domain windows is determined based on at least one of a number of repetitions, a number of slots, or a number of symbols.
